The cartridge of an electric screwdriver squeezed the bat and is not unclenched. Description, general information

The cartridge of an electric screwdriver does not clamp the bat

Each active user of the tool faced a situation when he jammed the clamping mechanism of the cartridge of the Interskol, Makita or any other brand electrical screwdriver. This constructively simple but functionally significant node is subjected to serious dynamic, vibration and shock loads. Dust, metal shavings and other small mechanical fractions also penetrate it. all these factors lead, if not to fatal breakdowns, then to periodic failures in the operation of the mechanism.

Typical cases in which Metabo, Dewalt, etc.:

  • When trying to use a drill of maximum permissible size, the fists are diluted to the maximum, after which it is not possible to reduce them with the application of standard efforts;
  • It is not possible to extract a drill or bat clain in a cartridge. the fists are not divorced. Often they are clamped unevenly, which worsens the fixation of the drill.

Less often, jamming of the sponges occurs during their free move during compression or unclenching. usually particles of garbage, scale, chips, etc.P., falling under the figure of one of the cams.

Methods of repair

Experts recommend, regardless of what reason the electric screwdriver jammed-what to do in the first place: into the inner cavity of the cartridge, including the surface of the cams, introduce a universal lubricant like WD-40. After 10-15 minutes, a rubber hammer (or ordinary, through the gasket) with moderate effort to fasten the cartridge and fists.

If the bat in the cartridge of the electric screwdriver Bosch, Texas, practice, etc., then (after lubrication) effectively solves the problem using two divorce keys. One clamp the base of the cartridge, the second neatly rotate its upper part. In order to avoid damage to the surface and the node itself, you should use soft, but dense gaskets of the skin type.

If your efforts have not led to anything, with minimal financial costs and extremely quickly the functionality of the tool will be able to restore the specialists of the workshops of the Successful Technique Service.

Drilling cartridge. malfunctions, breakdowns and methods of resolving them

Clime drilling cartridges for household drifts are produced in three modifications:

The body of the key cam cartridge is made in the form of a hollow hardened cylindrical sleeve (tsangi), on the outer surface of which a rotating adjustment clip is installed. On one side, the cylinder is attached to the drive shaft of the drill, and on the other hand there are fists (petals) for attaching the cutting tool (core, taps, deposits, etc.). When the adjustment of the adjusting clip, steel fists with a special thread move along the guides. If they come closer to each other, the drill is clamped. If they diverge from each other, the tool is released. The convergence and removal of the fists depends on the direction of rotation of the clip. Reliable fixation of the drill is ensured by tightening the clip of the cartridge with great effort. For this, a special key or fast.sounding is used. on quick.and.sound cartridges. a coupling.

The key helps to clamp the drill and easily unscrew the adjustment clip. In cam clamping cartridges, cords of various diameters have a cylindrical shank are fixed. Most often, the cartridges of domestic electric drills are designed for a core with a diameter of 0.8 to 10 mm or from 1.5 to 13 mm.

Why and when to change?

The clamping device should ensure the drilling of holes with acceptable accuracy. But over time, seating on the shaft and fists wear out, the cartridge begins to beat. That is, the working zone of the drill begins to go from side to side when rotated, and the hole is drilled with deviations both in place and in diameter. The wear of the cams does not allow to reliably fix the loser, and they stop at the load. There is only one way out. to change the worn cartridge to a new.

The bat in an electric screwdriver is stuck what to do

Any user of electric screwdriver met with the problem of jamming the cartridge. He is constantly subjected to vibrations, dynamic and shock waves. The chips from the metal, small mechanical particles, dust. which leads to malfunctions in the operation of the mechanism after a certain period of time, gets into the electric screwdriver. The article will talk about how to open the jammed cartridge of a screwdriver.

The cartridge is called fasteners, where the drill is fixed. Usually, standard drills are equipped with its fist.

Cases when the fasteners of the screwdriver jamming:

  • Fists do not move, but it is not possible to extract a grown drill or bit. During this fists are unevenly clenched, which complicates the fastening of the drill.
  • During the use of a drill too large, the fists are unclenched to the maximum, as a result of which it is not possible to reduce them by making great efforts.

In rare cases, sponges are jammed during their free walking when unclenching or compressing. in most cases it is provoked by particles of garbage, chips, okalina and other, which fell under the figure of one of the cams.

Professionals advise primarily inside the cartridge, which includes the surface of the cams, pour universal grease like WD-40. This is recommended for any reason to jam. After ten to fifteen minutes, to stand it and fists with moderate effort by a regular hammer through the gasket or rubber.

From such vibration, it will loosen the grip and release the tool. If necessary, after the introduction of universal lubrication, the cartridge can be a little warm with a hairdryer. In addition to the lubrication of WD-40, you can use machine oil.

One way or another, it is necessary for the fluid to penetrate deep enough inside, where the point of its contact with the drill is located. This method is suitable for both owners, both standard fasteners and fast.packed.

In the event that the battering is jammed, then after lubrication the problem is quickly solved by using 2 divorces.

With the help of one, the base of the cartridge is compressed, and the other carefully rotates its upper part. In order not to damage the surface and the node itself, it is recommended to use soft and dense gaskets like the skin.

In addition, in order to open the cartridge, it is necessary that it cools. In some cases, this one of this action is enough for the fists to release the drill, and it could be extracted.

The last way is the complete immersion of the drill into machine or vegetable oil for one hour. In the event that it is absent, you can use gasoline. When combining the above methods, it will be much faster to get.

If the problem cannot be solved independently, it is worth resorting to the help of competent specialists of workshops, who in a short time eliminate the malfunction.

What it is?

This part is a cylinder made of metal mounted to the shaft of the tool in question. Its main task is to fix the bit of fasteners. Note that such a part is attached to a screwdriver using an internal thread located on a cartridge, or using a special car necessary for fixing on the shaft.

Quick.ashmous are the most common type. The shank is clamped by turning the instrumental sleeve. We are talking about shanks with a diameter of 0.8 to 25 millimeters. The only serious drawback of this product is a high price than the same key sleeves. There are enough seconds to fix the element in the BZP. In this case, it is not required to use any auxiliary mechanisms. In the case of fast.and.packed solutions, the adjustment sleeve canvas is corrugated, which facilitates the rotation of the cylinder. The pressure on the shank of the product is adjustable using a special locking element.

True, after time, parts of the clamping mechanism become unusable. For this reason, a gradual weakening of the clamp occurs, so the sleeve cannot fix a large.sized round shanks.

Do.it.yourself electrical circuits repair

This is a mobile element of the tool, which consists of many rubbing details. In the process of work, he is worn out as a result of the action of the friction forces, shock forces and other factors. The beating of the cartridge, its excessive backlash can frighten an inexperienced master. In some cases, it is not always possible to allocate time or finances for contacting a repair workshop. Therefore, we will consider how to do on our own when repairing various tools of the tool.

Repair of an electric screwdriver with your own hands with the backlash of the cartridge

A small backlash within 1 mm usually does not create visible problems during operation. With a larger value, attention should be paid to the state of the gearbox. So, the procedure is as follows:

cartridge, electric, screwdriver, unclenched, description
  • Unscrew the bolts of fastening the upper cover of the tool. Take it off.
  • Unscrew the electric motor from the gearbox. We examine the mounts.
  • We disassemble the gearbox. Often the cause of the breakdown is a malfunction of the sleeve inside. It is possible to remove the sleeve using the actions described at the beginning of the article (we look at how to remove the cartridge manually). The sleeve is easily extinguished by hand.
  • We replace the sleeve. Then we collect everything in the following sequence: sleeve, shaft, sleeve bearings, locking ring. Lubricate the rubbing details.
  • After that, we collect a gearbox in the reverse sequence. We fasten it to the electric motor.
  • Collect the housing of an electric screwdriver.

Repair of an electric screwdriver with your own hands when beating a cartridge

The main culprit of this problem is the electric screwdriver gearbox. To make sure of this, you need to remove it, dismantling it in the above way. Specifically, this breakdown may indicate several problems in the gearbox, which we will indicate below. The reason may be:

  • violation of the geometry of the gear shaft;
  • development of gears;
  • malfunction of the supporting bearing of the shaft;
  • wear of the pins fixing the satellites of the planetary gear.

The above details are produced only in factories, so you will not be able to make them yourself. You just have to purchase them and replace failed.

Types of fastening

The mount occurs using:

The first mount is named after. BUT. Morze in the XIX century. The connection occurs due to the clutch of the surfaces of the shaft and cone with the hole due to identical cones. The mount is widely used due to simplicity and reliability.

In the second form of the connection on the shaft and cartridge, the thread is cut. Combination occurs by winding the cartridge on the shaft.

The third type is a modification of threaded mount. for reliability, the connection is fixed using a screw. He mainly has a head for a cross screwdriver and left.handed cutting. You can see the screw only by fully opening the fists.

Determination of fastening

The mounting of the cartridge is determined by its visual inspection. Morse cone is marked as follows. 1-6 B22. The first numbers are the diameter of the shank of the nozzle used, and B22 is the actual cone actually.

The threaded connection is also indicated by numbers and letters, for example: 1.0. 11 m12 × 1.25. The first part of the marking again means the diameter of the shank of the nozzle used, the second is the metric value of the thread. In imported electrical screwdrivers, the value is indicated in inches.

Moments of the appearance of the defect

Often this situation arises when trying to use the drill of the maximum possible diameter. Fists are spread out until it stops, after which they cannot be reduced. At the same time, the electric screwdriver itself is working, but it is impossible to use it.

And it happens that it is impossible to extract a already fixed drill. it is impossible to dilute fists.

Sometimes jamming can occur during the installation or removal of the drill from the cartridge. Most often, the cause of this is garbage or chips that got inside the mechanism.

Debugg

Regardless of the reasons that led to jamming, it is recommended to spray a little spray WD-40 inside the cartridge and wait 10 minutes. Then you should stand its body and fists with a rubber or wooden hammer. In the absence of a WD-40, kerosene can replace it.

If this does not help, then you can try to increase the force using two divorce (gas) key. One is clamped by the upper part of the cartridge, the other is rotated by the lower. In the case of only one key, instead of the second, you can use a vice. In order not to damage the surface of the part, the clamp is made through soft, but dense gaskets. for example, leather.

How to open a screwdriver cartridge

Professionals advise primarily inside the cartridge, which includes the surface of the cams, pour universal grease like WD-40. This is recommended for any reason to jam. After ten to fifteen minutes, to stand it and fists with moderate effort by a regular hammer through the gasket or rubber.

From such vibration, it will loosen the grip and release the tool. If necessary, after the introduction of universal lubrication, the cartridge can be a little warm with a hairdryer. In addition to the lubrication of WD-40, you can use machine oil.

One way or another, it is necessary for the fluid to penetrate deep enough inside, where the point of its contact with the drill is located. This method is suitable for both owners, both standard fasteners and fast.packed.

In the event that the battering is jammed, then after lubrication the problem is quickly solved by using 2 divorces.

With the help of one, the base of the cartridge is compressed, and the other carefully rotates its upper part. In order not to damage the surface and the node itself, it is recommended to use soft and dense gaskets like the skin.

In addition, in order to open the cartridge, it is necessary that it cools. In some cases, this one of this action is enough for the fists to release the drill, and it could be extracted.

If the problem cannot be solved independently, it is worth resorting to the help of competent specialists of workshops, who in a short time eliminate the malfunction.

And what methods to cure a jammed cartridge from an electric screwdriver do you know?

The role of the cartridge in the reliable fastening of the drill

Clime drilling cartridges for household drifts are produced in three modifications:

In the design of the cam clamp cartridge, you can understand with proper patience

The body of the key cam cartridge is made in the form of a hollow hardened cylindrical sleeve (tsangi), on the outer surface of which a rotating adjustment clip is installed. On one side, the cylinder is attached to the drive shaft of the drill, and on the other hand there are fists (petals) for attaching the cutting tool (core, taps, deposits, etc.). When the adjustment of the adjusting clip, steel fists with a special thread move along the guides. If they come closer to each other, the drill is clamped. If they diverge from each other, the tool is released. The convergence and removal of the fists depends on the direction of rotation of the clip. Reliable fixation of the drill is ensured by tightening the clip of the cartridge with great effort. For this, a special key or fast.sounding is used. on quick.and.sound cartridges. a coupling.

The key helps to clamp the drill and easily unscrew the adjustment clip. In cam clamping cartridges, cords of various diameters have a cylindrical shank are fixed. Most often, the cartridges of domestic electric drills are designed for a core with a diameter of 0.8 to 10 mm or from 1.5 to 13 mm.

Why and when to change?

The clamping device should ensure the drilling of holes with acceptable accuracy.

But over time, seating on the shaft and fists wear out, the cartridge begins to beat. That is, the working zone of the drill begins to go from side to side when rotated, and the hole is drilled with deviations both in place and in diameter. The wear of the cams does not allow to reliably fix the loser, and they stop at the load.There is only one way out. to change the worn cartridge to a new.

Drill device. what you need to know about the tool?

The convenience of not the simplicity of implementation provided the Popularity with the camer. But it is not without flaws. One there is difficulties in work with malehan drill. Kutsey the product can simply fall inside. You can still fix it by putting the drill in a horizontal position, but you can’t press on its surface very well. If another drill was inserted into the drill, it is an option to extract it by checking the adjusting ring in the corresponding direction. Manually this occasionally goes to do, for this purpose there is no special key that acts like a lever, increasing the effort. When, it is also not recommended to tighten the drill without a key. the more not just the dialect of the drill, the more reliable you need to make the mount.

When buying fasteners, make sure that it is rubberized. so you will injure your hands less when fixing the tool.

The work of fast.and.packed fasteners. the second most popular. is possible without a key. It is enough to insert a drill and crank the lever, often this can be done

With one hand. Fixation of the drill, which is provided by this type of cartridge, is quite enough for most works, however, compared with the classic fastening version, it is inferior in reliability, and it is more expensive. The main advantage of fast.fastened fastening is the speed of replacing the drill and the security of the process, since such a cartridge is deprived of teeth that can injure hands. The absence of a specialized key is also a significant advantage! Experienced builders know how easy it is to be lost, so very often you can see the key with wrap with tape or island to the wire.

True, this does not add convenience, but at least some confidence appears that the key will not have to be sought throughout the construction site. How to change a drill in an electric screwdriver? The scheme is absolutely identical. the cartridges of most drills are similar to fasteners in screwdrivers. Of course, the last tool cannot be a full.fledged replacement of a high.quality drill, if only because the fasteners are not provided for drills with a large diameter, and the turnover of an electric screwdriver, as a rule, is less.

Recommendations and tips

How to unscrew the jammed cartridge on an electric screwdriver? To do this, you need to pour lubrication into it, for example, WD-40. About five minutes should be wait to penetrate all the holes and grooves. For this to happen faster, you can use the hairdryer. Warm them a cartridge and then slightly hit the fists with a hammer from all sides.

It is important to know that the cartridge is unscrewed only after cooling the device. From the heated tool to remove the element will be great difficulties, because the elements are firmly fixed in the nest.

electric screwdriver and its design features

You should start repairing an electric screwdriver with your own hands with familiarization with its design. The main element of the electrical screwdriver is an electric motor. Screwdrivers are both network and battery type. The use of network electric screwdriver resorts less often, due to such a drawback as the need to connect the tool to the 220V network. The battery.type tools are more popular, as they allow not only the repair work of the house, but also beyond its borders.

The main nodes of the battery electrical screwdriver are:

  • Frame. Usually all screwdrivers are made of durable plastic.
  • Start button. It is arranged so that the number of revolutions of the cartridge depends on it.
  • Electric motor. In the battery tools, single.phase collector.type and direct current engines are used. The engine is a rotor, a stator in the form of magnets, as well as a brush unit.
  • Gearbox.
  • Effort regulator.
  • Reversion switch.
  • Battery. It is usually removable and often equipped with a product in a double copy.
  • Cartridge. As a rule, fast.and.packed cartridges are used.

Some models are additionally equipped with LED lighting lights, as well as battery charging indicators. Returning to problems with an electric screwdriver, it should be noted that any of the above elements can cause a tool malfunction. What is needed for repair? First of all, it is required to find the cause of the breakdown, and then make the appropriate decision to eliminate it. The tool can be divided into two parts: electrical and mechanical. Initially, it is required to find out what is the problem of the inoperability of the electrical screwdriver: in mechanics or electrician. This will not be difficult to do, so we consider the breakdown in more detail.

Malfunctions of the mechanical part

It is possible to identify mechanical malfunctions of screwdrivers by such a feature as the audibility of the functioning of the electric motor. When you press the start button, signs of the electric motor are heard, but at the same time the tool cartridge does not rotate or the characteristic sounds of a malfunction are heard during rotation.

The device of an electric screwdriver is quite simple, but a significant disadvantage is that all elements are almost 2-3 times smaller than electric drill. The mechanical possible breakdowns of electrical screwdriver include the following malfunctions:

    Bench of the cartridge. Despite the fact that fast.sounding cartridges are more universal and simple in work, their significant drawback can be called a low service life. It is impossible to fix a fast.packed cartridge, so if the tool refuses to hold a drill or bit, then the cartridge should be removed and replaced with a new. This is one of the most frequent malfunctions of the tool, but you will not need to disassemble an electric screwdriver.

It should be noted that the small dimensions of the mechanical part of the tool are somewhat complicated by the process of repairing the tool, so be sure to be careful when carrying out repair work.

Malfunctions of the electric part

Unlike a drill, screwdrivers function mainly from batteries. This means that different electric motors are used in the design of these tools. Determining the malfunction of the electrical part of the electrical screwdriver is not difficult. If the battery is charged, but when the “Start” button is pressed, the sound of the electric motor is not heard, then the reason is the breakdown in the electrician. Consider the main types of malfunctions of the screwdrivers on the electric part.

  • Battery malfunction. Initially, you should pay attention to the battery. As a rule, boat-quality nickel-cadmium batteries are used at screwdrivers. They have a significant drawback, which consists in the need to charge it only when it completely “sits”. Such batteries cannot be recharged, as this reduces their service life. If one day an electric screwdriver refuses to function, then do not rush to disassemble it, make sure that the battery is working and gives out a charge. You can check by connecting the second battery. The battery charge can also be checked using a tester, which should show the corresponding voltage value.
  • Charger malfunction. There is a special charger for charging the battery. If the battery is discharged even after you have charged it, then you should check the integrity of the charger. For these purposes, there are usually light indicators on charging devices. If they are not, then you need to use the multimeter.
  • Failure to include button. It is necessary to check the start button, since often the cause of its inoperability is the oxidation of contacts or dust. The tool should be disassembled, then clean the contacts. Buttons usually in screwdrivers have a function of regulating the speed of rotation of the cartridge, for which the transistor is installed. If the tool works, but the function of regulating the speed number is absent, then you need to replace the transistor.

Now you know the main signs and types of malfunctions of an electric screwdriver. To repair it, you do not need to be a specialist, but enough to stock up on the tool and free time.

DIY repair for an electric screwdriver for an electric screwdriver

To date, many are used by such an instrument as an electric screwdriver, so a high demand for them is not surprising.

#ShortsCordless Electric Screwdriver Kit 

Very often the device is out of order, and the buyer is in a hurry to the repair shop, giving money for repairs.

I don’t always want to do this, of course, therefore in our article we will help you get acquainted with the device of an electric screwdriver in more detail. You can cope with some problems yourself.

We will consider various cases of breakdowns of electrical screwdriver, namely: we will deal with the most frequent breakdowns of such an important detail of the tool as a cartridge.

A cartridge of electrical screwdriver: description, function

The cartridge is a metal cylinder with a cavity inside, equipped with a ring and a regulatory sleeve. It is fixed on the shaft. With its help, a drill or a grinding nozzle is securely fixed in it for further work.

Fixation of the working body of the tool (drill) provides thread. The drill in it is delayed in two ways.

The first method is to tighten it with a special key, in the second method, the drill tightening occurs when the cartridge rotates in the direction opposite to the axis of rotation of the drill.

How to disassemble the cartridge of an electric screwdriver

Despite the fact that today there are many models of screwdrivers on the market, a common approach to the removal of such an element as a cartridge, they have one. Now we will briefly describe it.

In order to promote it, you need to remove the screw that attaches it to the shaft. It is located inside the cartridge, rotation of the screw should be done clockwise. After you unscrewed the screw, you should jerk the cartridge in the opposite direction.

Attention! When trying to unscrew it manually, it is necessary to put the drill on the second speed if it is two.speed. When buying a tool, it is advisable to lubricate the screw with machine oil.

In some cases, when this element does not want to succumb, then you should put the tool at the first speed, clamp it in the palm of your hand, turn on the reverse to the left. The cartridge should easily get off the thread.

How to replace an electric screwdriver cartridge

It will not be easy to replace it with an unprepared user, since without the help of a special tool with your bare hands you will not be able to do this. The ways that can be removed by two, we will consider them in our article further. In order to change it, you should pay attention to the actions that we described in the article above. Dismantling is performed by the following tools:

  • Hexagonal key-usually 10 mm G-shaped metal rod. It should be fixed by its short part in the cartridge, the long one must be rested with anything, for example, on the table. Turn the cartridge, then remove it with the key turning.

We examined the method of dismantling with the key. The way to remove the element is manually described above.

Important! In particularly severe cases of jamming of moving elements, you have to complete the analysis of the tool body with a recess spindle with a gearbox and a cartridge.

To do this, you will need a vice in which you will clamp the tool, and a trumpet key that you will turn off the cartridge. Facilitate the implementation of this sampling task designed to insert a wrench.

But they are not found on all models, so you will have to cope with the above way.

This is a mobile element of the tool, which consists of many rubbing details. In the process of work, he is worn out as a result of the action of the friction forces, shock forces and other factors.

The beating of the cartridge, its excessive backlash can frighten an inexperienced master. In some cases, it is not always possible to allocate time or finances for contacting a repair workshop.

Therefore, we will consider how to do on our own when repairing various tools of the tool.

Repair of an electric screwdriver with your own hands with the backlash of the cartridge

A small backlash within 1 mm usually does not create visible problems during operation. With a larger value, attention should be paid to the state of the gearbox. So, the procedure is as follows:

  • Unscrew the bolts of fastening the upper cover of the tool. Take it off.
  • Unscrew the electric motor from the gearbox. We examine the mounts.
  • We disassemble the gearbox. Often the cause of the breakdown is a malfunction of the sleeve inside. It is possible to remove the sleeve using the actions described at the beginning of the article (we look at how to remove the cartridge manually). The sleeve is easily extinguished by hand.
  • We replace the sleeve. Then we collect everything in the following sequence: sleeve, shaft, sleeve bearings, locking ring. Lubricate the rubbing details.
  • After that, we collect a gearbox in the reverse sequence. We fasten it to the electric motor.
  • Collect the housing of an electric screwdriver.

The above details are produced only in factories, so you will not be able to make them yourself. You just have to purchase them and replace failed.

A cartridge of an electric screwdriver cartridge

Structurally in the tool case, this mobile element is fixed in three ways:

Fastening with the cone Morses is known long ago and consists in the following. The shaft has the shape of a cone that repeats the surface of the surface inside the cartridge. the same cone. Combining them in a certain way, receive a reliable connection.

The sharing of the shaft with the cartridge using a threaded connection is the presence of threads at the end of the shaft, on which a cartridge has freely wound, having the same thread.

The fixing screw is most often used as an additional mount. Its head has notes under the cross screwdriver, as well as the left thread. You can see this screw by promoting the fists that cover it.

To find out what your mounting tool is, you must carefully inspect the tool body. Designation for each type of fastening has its own.
