Description

one

The invention relates to the finishing of parts, in particular, to the finishing of parts by the method of vibrating rolling.

There are known devices comprising a holder of a deforming element in which an electromagnet is used as a drive. The amplitude of oscillation of the deforming element is changed by adjusting the gap between the core and the electromagnet core.

These devices are not. They have the possibility of smooth adjustment of 6 wide ranges: the number of OSCILLATIONS (double moves) of the deforming element, the amplitudes of oscillations and the amplitude of vibration vibration.

Also known are devices containing a tool head for finishing, an oscillation drive, made in the form of an electromagnet, between which the poles are located. The amplitude control is made by moving stops limiting the swinging range 1.

Such devices do not provide high stability of oscillation amplitude.

due to insufficient rigidity of the mechanical limiters, there is no possibility of adjusting the torque of the core.

The purpose of the invention is to increase the quality of the device by changing the amplitude of oscillation.

This is achieved in that the device is provided with tips mounted on poles with the possibility of relative movement.

The drawing shows the scheme of the proposed device for vibro-rolling.

The device consists of an instrumental HEAD 1 and an electromagnetic actuator 2 containing movable measles 3, tips 4 and 5 located at poles 6 and 7. Movable measles 3 can oscillate around a fixed axis 8. The tips 4 and 5 use a flywheel 9 to move relative to each other friend in opposite directions. The movable measles 3 with the tool head 1 is connected by means of a pole 10 and guides I. To control the frequency of oscillations of the movable core 3, there is a winding W, and on the cores 6 and 7 windings

Wo and Wo are used to create a reference magnetic flux.

The device works as follows.

The constant current passes Jo through the windings Wo and Wo create equal constant reference magnetic fluxes, which through the movable measles 3 and the air gaps close into their conduits, i.e., the magnetic field lines created by winding Wo from pole 6 are closed through air gap 5, rolling cdr 3, air gap b {at tips 4, and magnetic power lines, and created by winding Wo from pole 7 through air gap 8g of movable core 3, air gap bz closes with tip 5.

Because Jo Wo and JoWj are equal to each other and. d (5g, measles in the absence of a control current will occupy a neutral position.

If the control current iynp varies sinusoidally, the value of the control magnetic flux will change and alternately amplify the reference magnetic flux. Anchor 3 in one case will occupy the right position, in the second one. The oscillation frequency of core 3 will depend on the frequency of the control current,. Le and the flux of the reference magnetic flux, it is possible to vary the torque within a wide range and achieve high stability of the oscillation amplitude, which is smoothly adjusted by the flywheel 9.

Due to the fact that the vibro-rolling device has the ability to smoothly regulate the number of double-lane strokes and the amplitude of oscillation with their high stability, the proposed device allows processing the surfaces of parts with any optimal microrelief.
