Abstract

The invention relates to the field of machine tools. The purpose of the invention is the expansion of technological capabilities by targeting in mutually perpendicular directions. The orientation mechanism is made in the form of a sleeve with an eccentric hole. A pin with a parallel key is located in the hole of the sleeve. The keys are placed in the grooves of the machine table. The keys of the two orientation mechanisms are located in one of the slots, and the key of the third mechanism is placed between the keys of the two mechanisms in a groove located perpendicular to the first. 3 il.

Description

The invention relates to: mechanical engineering, in particular, to means for orienting and adjusting on the table of the machine tool during machining relative to the tool or base surfaces, as well as to correct the relative position of the assemblies of mechanisms and machines during installation.

The purpose of the invention is the expansion of technological capabilities by targeting in mutually perpendicular directions.

FIG. Figure 1 shows a key, a slit; in fig. 2 - arrangement of prismatic keys, top view; in fig. 3 shows section A-A in FIG. one.

The device consists of 3 prismatic keys 1, two of which are mounted on the landing movement in one

the keyway of the intermediate plate 2, and the third key in the groove perpendicular to the first (Fig. 3). The cylindrical pins of the prismatic keys 1 are mounted in the openings of the bushings 3 eccentrically relative to the outer diameter of this sleeve, on which it is based in the hole of the plate of the device 4, the cylindrical part of the prismatic keys 1 is provided with a threaded end on which the washer 5 is installed and the nut 6 is screwed when the condition of self-braking of the sleeve 3 is reached, the ratio of its outer diameter to eccentricity e is chosen to be more than fourteen.

The device provides a rigid connection between the fixture plate and the table of the machine and at the same time a stepless adjustment of the fixture in 3 degrees of freedom, namely:

X; moving along In all other turning conditions, the center of rotation will vary, but is located on a line passing through the centers of the prismatic keys I and III. The device provides adjustment of the position of the fixture or part in 3 degrees of freedom: movement along the X axis, movement along the axis, and rotation.

moving along the Y axis; turn.

The maximum amount of movement and rotation is determined by the magnitude of the eccentricity of the sleeves.

The device works as follows.

The movement along the X axis is carried out by rotating the sleeves 3 of the prism-) Y of the tangs I and III in opposite directions by the same number of divisions, limbs.

The displacement along the Y axis is effected by: e1I by rotating the sleeve 3 of the prismatic is from I-key II (see Fig. 2). The rotation is carried out in two ways.

I method (see Fig. 4).

The rotation is made by rotating the sleeve 3 of the parallel key I (or III) relative to key III (W I) as the center of rotation.

II method (see Fig. 5).
