Description

The invention relates to the cutting of metals and can be used in honing holes.

The purpose of the invention is to improve the accuracy of processing.

Figure 1 shows the proposed device, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - view B in figure 1; figure 4 - section bb In figure 1.

The device includes a honing head comprising a body 1, a body shank 2 and a vibrator made in the form of a glass 3 connected to the body 4 of the spindle head and a sleeve 5, in the windows of which holders 6 honing sticks are placed. Between the housing 1 and its shank 2, an elastic torsion element 7 is installed, the sleeve 5 is telescopically connected to the sleeve 8, which receives oscillations from the vibrator cup 3. At the junction of the sleeves 5 and 8 there is a wedge mechanism consisting of a figured window 9 with two inclined surfaces in the sleeve

8, two spring-loaded wedge cams 10 installed in window 9,

It only works with the cams 10 when the inclined surface of the window 9 reaches the wedge surface, the cam 10, the movement of which is limited by the inclined walls of the shaped groove 12 in the shank 2. The rest of the path of the bushings 5 and 8 passes along due to the pinch of the spike 11 between

10 remote control with the right side of the window 9 and the cam 10. When moving back, this cam 10 does not transmit movement, and the other performs this function after meeting with the corresponding inclined

15 by the surface of window 9. The magnitude of the amplitude transmitted by the wedge fur-1 from the sleeve 8 to the sleeve 5 depends on the width of the groove 12 in the arrangement of the cams 10. And this place is determined by the amount of circumferential displacement of the body 1 relative to the shank 2. Thus, the amplitude the oscillation of the oscillations depends on the moment of the cutting forces and increases with the increase of the latter due to the corresponding shape of the shaped groove 12 in the shank 2 (its axial size increases in the same direction where the body 1 with the sleeves elastically moves

spike 11, fixed inside the sleeve - JQ 5 and 8 with respect to the shank 2).

and

5. On the shank 2 there is a figure wedge groove 12 designed to interact with the cams 10. The torque required for the operation of the vibrator is transmitted from the sleeve 5 to the sleeve 8 by means of a system of balls 13, which ensures free mutual axial movement of the sleeves 5 and 8 A similar ball system (not shown) is installed between the sleeve 5 and the housing 1 for transmitting torque to the sleeve 5. The device operates as follows.

When the machine is turned on, the honing head, mounted on the spindle, is inserted into the hole of the workpiece, begins to rotate and receives the specified radial unclenching of the bars. The torque from the cutting forces, overcoming the resistance of the elastic torsion element 7, causes a circumferential displacement of the body 1 relative to the shank 2. Together with the body 1, the circumferential displacement is obtained by means of ball systems 13 of the sleeve 5 and 8. When the sleeve 8 rotates, axial oscillations are reported from the glass 3.

Consequently, the removal rate in areas with a high allowance will be provided more than places with a minimum allowance, which reduces the time required to obtain surfaces of a given accuracy or increase the target processing accuracy economically.
