Description

one

The invention is intended for the finishing treatment of conical surfaces and can be used in shipbuilding, as well as in other branches of engineering where it is necessary to process deep holes or external surfaces with high accuracy in terms of geometrical parameters.

A caliper turning support for tapering surfaces, which is installed at an angle along a reference bar, contains a slider housed in a housing on rolling and sliding bearings.

The proposed caliper differs from the well-known in that one group of supports is rigidly fixed in the housing, the other is movably on adjustable spring-loaded rods, and the housing itself is equipped with a platform with which it contacts, when adjusted, with an optical gauge probe, movable relative to the reference ruler.

The rolling bearings are mounted in the housing and the lid, three in-line on each guide face of the slide, two of which are located at the bottom and one third at the top of the body.

This embodiment of the device improves the accuracy of processing.

Pa figs. 1 shows the support of a turning-and-boring lathe with the cover removed; in fig. 2 is a section along L - A in FIG. one; in fig. 3-

principle of the device for accurate reading of the angle of rotation of the caliper; in fig. 4 is a diagram of the installation of a device for reading pa; pas figs. 5 is a diagram for calculating a probe movement amount.

The caliper consists of a case Y, a cover 2, a slide 3 and a mechanism 4 for its movement (Fig. 2). In case 1, a group of supports 5 for sliding and supports 6 for rolling on adjacent faces of slider 3 is rigidly strengthened. Another group of supports for rolling 7 on adjacent edges of slide 3 opposite to group of supports 5 vt 6 is hinged in case 1 and cover i2.

The rolling supports 7 are mounted on track 8, through a spherical conductor, they are clamped by a damper 9 (for example, with cup springs) through the stem 10 by means of a nut 11 and a cup 12.

The rolling bearings 5 and 7 are mounted in the housing / and the lid 2 (Fig. 2), three in-line on each of the guiding faces of the slide 3 (Fig. 1). Two of these supports are located at the bottom, and a third - at the upper ends of the caliper housing.

To tune to a given angle, the caliper is equipped with a device for accurately counting the angle of the copus. The opo consists of a fixed base 13 (Fig. 3) with a precise ruler 14. With respect to the exact ruler 14, the housing 16 with the optical reading device 17 and the probe 18 move along the guide rolling pins 15 and the probe 16 is pressed with the probe IS all the time.

The device for reference is mounted on a San x 20 (Fig. 4) caliper so that the probe 18 rests on a specially prepared stop ./ on the caliper. The surface of the anvil 21 lies in a plane passing through the axis of rotation of the caliper.

To adjust the caliper to a predetermined turning angle, the caliper is rotated so that the movement of the probe 18 (Fig. 3), counted using the optical reading device / 7, is equal to the predetermined value T, which corresponds to the preset angle a of rotation (Fig. 5).

In this case: t H ig a,

where H is the distance from the initial point of contact between the probe and the caliper;

and - the specified angle of rotation of the caliper.

After turning, the caliper is secured. During turning, the slider 3 moves from the mechanism 4 along the slide guides 5 and the rolling 6 H 7 (Fig.

1) to the required depth of processing.
