DIY Hair Clipper Repair

click fraud protection

Most of the clippers are not much different from the old Soviet-era razors, resembling modern grid models. The vibrator stands inside a pendulum, the blade performs not strictly horizontal translational movements, describing a large arc. One position: the edges of the movable and fixed knives coincide, they will be parallel, on the opposite side there is a slight angle. Normally, there is no indication of a malfunction. Repair hair clippers with their own hands tied on small AC motors, mechanical parts. Adjust the cutting edge clearance.

Device for hair clippers

. We hope to teach those who want to fix the hair clipper. The question is not trivial, as it seems at first glance deceived by the apparent simplicity of the design. Surprisingly, the only book describing the repair of hair clippers, owned by Lepaeva, dates back to 1970.Falling interest, simplicity of design? There are few professionals, there is no time to write manuscripts, urgent matters are bothering. Regardless of the principle of operation of the hair clipper inside, there are:

  1. Transformer, the primary winding of which is often designed to work with voltages 127, 220 V *.
  2. Stator coils. Two by the number of supply voltages.
  3. Steel core.
  4. Gates, pendulums, another similar mechanism that begins to vibrate when an alternating field appears.
  5. Knife block, formed by mobile and fixed parts.
  • Switching power supplies are gradually replaced by bulk transformers with laminated cores. The small size of digital technology attracted the designers of clippers.

Whether the pendulum( Moser), drawstring is worth inside the hair clipper, both are held together by two return edge springs. The stator does not touch the rotor, otherwise, working, gave a grinding sound. Regulatory purposes will serve a special screw mechanism. The pendulum is often mounted on a bearing. Fails - noise will be heard. The movable part is made as light as possible, the knife can sit on a plastic part( the specific density of the polymer is several times smaller than steel).The pendulum may crack in the bearing area. Previously, you had to put the clamp, change the part, today's adhesives firmly take. Try Titan.

Coils

Hair clippers delight coils. Ordinary chokes, coils schoolchild. Find out the brand of wire, buy a segment of the desired length on the market, covered with varnish insulation, make a device for rewinding, start repairing a hair clipper with your own hands. The old coil is called. It will help to make sure: the fault is hidden here, not the mechanical part. Burnt transformer( not pulse), rewinding is not difficult. The second step begins laying coils. Use a device made up of two pairs of racks located opposite each other at different edges of a long plank. The axes of one support the old coil, the other - takes the wire. Having noticed the breakage of the beginning or the end, wait a little to buy a new wire on the market, wind back the existing wire, subtracting the torn part. It is important to maintain the correct number of turns, the location of the findings.

Winding of new coils is carried out by the described device. The coils lie tightly, the glue is superfluous, the wire adheres by hand. Tension helps to lay the coil with wire even layers. The coils are laid down by the shuttle method, from one edge to the other. After the procedure, you need to ring the coil, to ensure the integrity of the wire. If a single voltage is used at home, a wire longer from one unnecessary choke is applied to restore the burned one. Enough length - the market will wait.

Lubricant

Hair clipper device is unsophisticated. Engine, chain of transmission of the moment of movement. The anchor of the hair clipper rarely breaks, except for the case with a crack. Lubricate and clean the appliance. Prepare regularly. Use VNII MP - 260, a soft brush. The anchor stroke is sometimes adjusted by a screw, see that in all positions the teeth of the moving part do not extend beyond the frame.

In many instances there is a trimmer, taking energy from the same motor through a transmission mechanism.

Inspection procedure for a hair clipper

At first the cord is inspected, the first step eliminates a significant part of the breakdowns. The inside is often screwed into the case of the block, you can check the presence of the supply voltage tester. In the second turn the switch, the switch of a voltage ring. If necessary, the problem is eliminated( in the absence of parts, short-circuit the contacts).Particular attention is paid to soldering.

When the hair clipper doesn’t work satisfactorily, the case is explained by an incorrect head setting, it’s time to inspect and lubricate the product. Return springs wear out. By the way, the tensioning mechanism is also regulated, if the amplitude of the knife movement is incomplete, pay attention to this detail. There are specific moments. The casing of the knife block should be centered relative to the body of the hair clipper. If this is not the case, the parts are adjusted to each other by filing. Pay due attention to adjusting the relative position of the knives. In Moser, for example, on the side you will find a screw for a slotted screwdriver that adjusts the correct clearance. The machine may not work at all or cut perfectly depending on how correctly the regulator is turned. Samples are conducted on a material resembling wool.

The knives are set so that the edges of the moving and stationary go flush. In pendulum models, a position is selected for adjustment when the teeth are parallel. When tilting, one side will be lower than the other. To adjust the relative position of the Moser two screws that support the fixed part. The assembly is hanging on the holder. The bolts are relaxed with a screwdriver, after which the exhibition takes place as desired. Then the fastener is tightened. In the case of a slotted screwdriver, use the widest possible tip, the iron is not hot, it will be damaged when twisting.

Knives are often blunt. Sharpening involved special machines. They are a kind of potter's wheel, aluminum disc. To begin with, the surface of the table is carefully cleaned and dried. After the abrasive is poured on top, it is leveled with a flat plate on the area. The knife is located on the disk strictly along the radial line. The laser pointer is built in the machine tool-grinding. The knife is clamped with a special clamp, the circle starts. The master gently presses from above, the sparks must fly in the direction of the teeth. At the end of the procedure, the knives are washed in a solution, lubricated. Inspection is carried out on a piece of wool or other material resembling hair.

The nuances of the design cause small differences that characterize the self-repair of their own clippers. In Moser, Torx screws are often used in the knife block, and the return spring is one - two-sided.

The steel helix is ​​hooked onto the movable knife, which is threaded into the anchor during installation. The slice level control presses on the same spring, adjusting the position of the knife. In the same models there are no coils at all. Inside there is an engine equipped with an eccentric shaft. The rod moves the knife to and fro. Accordingly, there are no magnets inside, the knife is extremely light, due to which the efficiency of the device increases( the inertia of the moving unit is minimal).The power board supplies the( externally collector) motor with voltage. Check the operation of the motor is easy - ring the windings, the resistance should be a few tens of ohms.

The board is assembled on chips and is powered, including the battery. To replace the source, you will have to get hold of a Torx screwdriver on the seven, after removing the case, all the necessary operations are performed. The battery itself resembles a finger-type batteries, assembled in a bundle of three pieces, but in fact it is easy to charge from the AC network through the adapter. Clearly, inside the switching power supply, on this issue you can run through our website, there are a lot of articles posted on how to proceed.

In brief, inside there is a row of input filters through which voltage is applied to a key element( transistor, thyristor, less often a relay).The control signal generates a high frequency generator. Due to this approach, it is possible to reduce the weight and size of the transformer. Actually, the technology is used today in power supplies. This applies to cell phones, laptops and other household appliances. In this sense, repairing a dog grooming machine is no different from high technology. What could break here?

  • Diode Bridge.
  • Capacitors and filter resistors.
  • Transformer.
  • Key( transistor, thyristor).
  • Generator.

The output also includes Schottky diodes. Selected for low voltage drop on open junction. Thus, repairing hair clippers with their own hands requires basic knowledge in the field of electronics. That's it for today! We sincerely hope that we help readers overcome the fear of household appliances.
