Description

The invention relates to mechanical engineering, in particular to faceplates for fastening grinding and polishing wheels on spindles of grinding machines, and can be used in the machining of parts such as rotary bodies and flat surfaces with oscillations;

The purpose of the invention is to expand technological capabilities by smoothly adjusting the angle of inclination and amplitude of oscillations of a circle with

The drawing shows the device, the cross section

The device contains a flange 1 and a clamping flange.2, the steel between which ends through a cardboard pad 3 is placed a cipher circle 4 o Flange 1 is filled with an internal spherical base surface, with which it interacts with the possibility of rotating the circle in any plane with a spherical head cantilever mandrel 5, which is fixed to the machine spindle (not shown) along the Morse taper, on the outer cylindrical surface of the cantilever mandrel 5 the mounting disk b is fixedly fixed with the bevel at an angle equal to the field the maximum angle of inclination of the circle 4, butt, interacting with the flange face, which is angled at the same angle, 1 o

In the inner bore of the clamping flange 2 there is a lock ring 7 made of steel for fixing the angle of rotation of the circle 4 with screws 8. A friction coating, for example, of asbestos friction plastic, is applied to the working surface of the lock ring and the spherical head of the cantilever mandrel 5.

The device works as follows.

For a half-turn of the spindle grinding wheel 4 point and

on its percferia, moves to position a, for the second half-turn of the circle it returns to its original position. Consequently, for a complete revolution of a circle, all its peripheral points will move along the axis of rotation, equal to the magnitude of the oscillation amplitude

BUT. .

The angle of inclination of the grinding wheel is set when the latter is stopped by turning the flange 1 relative to the spherical cantilever mandrel 5o. Before this, release the screws 8 and loosen the clamping of the locking ring 7 to the spherical mandrel. ,

The installation disk 6 and the hub of the transition flange 1 have beveled ends at an angle equal to half the maximum angle of the circle 4 This is done to add or subtract these angles when turning the flange 1 relative to the spherical cantilever mandrel 5 when the latter is stationary.

In order to set the zero angle of the circle 4, it is necessary to turn the transition flange 1 by 180 ° around the horizontal axis with the fixed mandrel 5, i.e., point a 1 arc Must be in the lower position

To set the maximum angle of inclination of the circle 4, it is necessary to turn the transition flange 1 relative to the fixed mandrel 5 by 180 about the horizontal axis, i.e. point a will take the upper position. After setting the angle of rotation, screws 8 are tightened and the abrasive tool is edited

Thus, the proposed device, providing oscillation, intensifies the process of processing due to the increase in the contact length of the circle and., Details, the presence of an angle
