Abstract

The invention relates to auxiliary devices for honing machines, intended for machining internal surfaces of rotation and can be used to set the workpiece with respect to the tool for other types of processing, such as deployment, thread cutting, etc. The purpose of the invention is to improve the installation accuracy of the workpiece. The device comprises a housing 1 and a clamping element 2, which is supported on an intermediate insert 4 mounted on the guides 5 with the possibility of displacement along them relative to the axis of symmetry of the housing. The clamping element is kept from turning by the latch 6. The latch 6 is connected by means of a finger 8, which is installed eccentrically relative to the axis of the clamping element with a clamping element with the possibility of angular displacement of the latter relative to the finger 8. 2 Cp f-ly. 3 il.

The invention relates to auxiliary devices for honing machines, intended for treating the inner surfaces of the dowel and can also be used to set the workpiece with respect to the tool for other types of processing, such as deployment, cutting, etc.

The purpose of the invention is to improve the accuracy of installation of the workpiece by reducing the number of structural elements and thus reducing the mass of floating parts of the device.

Figure 1 shows the device, a longitudinal section; figure 2 - section aa in figure 1; Fig. 3 shows an example of the device.

The device consists of a housing 1, in the bore of which is installed with a gap P, an element 2 with a fixed workpiece B. When performed in the form

The bushings are supplied with a clamp nut.

The clamping element rests on the intermediate insert 4, which is mounted directly on the guiding directions 5 in the housing 1 with the possibility of displacement along them relative to the housing. The latch 6, holding 1J from turning the clamping element 2, connects it by means of a hinge 7 to a finger 8 mounted in the hole 1 of the intermediate insert 4 with displacement e relative to the axis of the clamping element 2. The strip 9 is designed to limit the axial movement of the clamping element 2 in clearance limits S.

When the clamping element 2 is in the form of a spring, the pin, the latch and the hinge are integrally formed as an elongated and unbent end coil of the spring f installed freely in the hole I made in the intermediate insert 4 with offset e relative to the axis of the clamping element. The second end of the spring is brought out through the slot C in the housing 1 to the outside to allow the spring to be diluted when the workpiece is installed. In this case, the bar 9 is folding and can be installed outside the device, not

Device work (. T following way.

The tooling B, processed by the tool 1), is inserted into the clamping element 2, fixed by the nut 3 or the bar 9 (as in FIG. 3). When tool D is inserted into the machined hole K, the blank B is self-aligning around the tool, making a number of necessary movements (Fig. 2): turning at an angle c | around the finger 8, installed and the hole of the insert 4, the linear offset by the value of & together with the insert 4 along the guides 5 of the housing 1, the inclination relative to the axis of the tool D in the case of a crossover of its axis and the axis of the hole K (Fig. 1). The amount of movement allowed is determined by the established gap P between the bore hole in the housing and the mating surface of the clamping element. As a rule, the gap P does not exceed 1.0 mm. The axis of the workpiece is tilted to align with the tool axis within the axial gap S due to the rotation of the retainer 6 in the hinge 7 or due to the elastic deformation of the bent end f of the spring 2 (FIG. 3) and in the gap at the interface with the hole 1. The gap S is set in the range of 0.5-1 mm.

.

When the tool P is beating, the workpiece B, together with the clamping element 2, is displaced relative to the finger by an angle C | (Fig. 2) and simultaneously with the insert 4 along the guides 5 in the housing 1 by the value L.
