Abstract

This invention relates to the watch industry. The purpose of the invention is to increase the productivity of the process of adjusting the wheels of clockwork mechanisms. If the beating amplitude of the wheel 2 is greater than the allowable one, the editing accuracy setting unit 9 gives the command Allowing to edit the trigger 10, which sends the command to the command output unit 13, the purpose of which is to output the impactor 14 with various electrically significant energy in accordance with the signal formed in block 11 to form the impact energy value. The purpose of the invention is achieved by minimizing the number of strokes needed to eliminate planar beats, since reducing the number of strokes leads to a reduction in the dressing time. 1 il.

The invention relates to the field of instrumentation, in particular, to the watch industry and is intended for use in the automation of various technological and assembly processes.

The aim of the invention is to increase the productivity of the dressing process by reducing the number of strokes.

The drawing shows a block diagram of a device enabling the proposed method to be implemented.

The device contains tribe 1 with wheel 2 mounted on it, centers 3 and 4, pulley 5, probe 6, sensor 7, amplifier 8, block 9, specifying the exact alignment, starting device 10, block 11 for forming the magnitude of impact energy, block 12 for determining the moment impact, command issuing unit 13, impact mechanism 14 and hammer 15 rigidly connected to the latter,

At the same time, tribe 1 with wheel 2 is installed at centers 3 and A, center 4 is rigidly connected with pulley 5, and the engine receives rotation (not shown). A probe 6 touching the rim of the wheel 2 transmits oscillations of the movable part of sensor 7, signals from the output of which through amplifier 8 arrive at the inputs of unit 9 to set the accuracy of the edit, unit 11 to form the magnitude of the impact energy and unit 12 to determine the moment of impact. The signals from the output of the starter 10 are fed to the input of the energy generation unit 11 and the input of the command issuing unit 13, the other two inputs of which are connected respectively with the output of the impact energy generating unit 11 and the output of the moment of impact determining unit 12, and the output of the command issuing unit 13 connected to the output of the percussion mechanism 14, the movable part of which is rigidly connected to the hammer 15 o

The Z axis is perpendicular to the X axis that coincides with the axis of the tribe. The Y axis is perpendicular to the XOZ plane and lies in the plane of the wheel 2o. The plane of the wheels 2 is rotated relative to the Y axis and makes an angle cp with the Z axis, which determines the size of the plane beating of the wheel 2

The process of editing the planar beats of rotating bodies is carried out as follows.

The preinstalled in centers 3 and 4 tribe 1 with wheel 2 is continuously transmitted through pulley 5

with rotation from a motor (not shown), in the presence of a plane beating, the wheels 2 jsjyn 6, rigidly connected with the movable part of the sensor 7, oscillates, amplitude

10 of which is equal to the magnitude of the plane beats, which allows the said sensor to produce a signal proportional to the magnitude of the planar beats, which, after amplification in the amplifier

If 8 is fed to the input of the block 9, specifying the accuracy of the edit, the input of the block 11 for forming the magnitude of the impact energy and the input of the block 12 for determining the moment of impact of

20 If the amplitude of the beating of the wheel 2 is more than permissible, the block 9, specifying the editing accuracy, gives the command Permission to Edit the Launcher 10, which will issue the command

25 block 13 issuing commands, the purpose of which is the issuance in percussion mechanism 14 of various largest electric energy in accordance with the signal formed in block 11

30 forming the magnitude of the impact energy.

In the case of a command to allow editing from the starter 10 to the specified block 11, the latter generates a signal proportional to the fixed value of the initial impact energy, which for a given type of wheel is constant

4Q In the event that after the initial strike by hammer 15 on wheel 2 with the specified fixed value of energy E, the beating of the wheel to be fixed continues to exceed the permissible value, then the block I1 of forming the magnitude of impact energy produces a signal proportional to the energy required for delivering the final blow, which

But if after applying a second strike with a hammer 15 on the selected wheel 2, the value of the planar beat of the latter becomes less than permissible, it is sent to a suitable bunker and they start to edit the next wheel.
