Description

The invention relates to metal-cutting machines, in particular to measuring and control devices for measuring and setting the position of the cutting head pivotally mounted on the upper support of a screw-cutting lathe. :. .. /. . . - .- ...

The invention can be used in the measurement and installation of the angular position of various geodetic, geophysical instruments, instruments of space technology, etc .., .- ..

The aim of the invention is to increase the accuracy of the installation.

The method is illustrated in FIG. 1-8.

The holder is mounted in the guides 13 of the transverse caliper and secured with M8 bolts. ..

The post 2 is mounted in the holder using an M10 threaded connection.

The MB 3 screw is used to secure the housing to the rack and the indicator to the housing.

The emphasis 4 is installed in the threaded seat located on the upper support. An emphasis is made on the support, which is therefore P, which, therefore, belongs to the front door and / or the upper suip® mouth.

The VK device has a corpus.

In the above drawings, there is a cutter head 6 of the upper support, and an indicator 7 of linear positioner $ w "(and of type GOST 577-66, a stylus 8 of the indicator of displacement, a mark 9 on the cutting head, scale 10, mounted on the transverse support , the handle 11 of the upper caliper, the handle 12 of the transverse caliper, the transverse caliper 13, 14 is the point where the indicator probe is against the vertical support wall P of the cutting head,

- A method of accurately fitting a carriage is as follows.

The upper caliper is set to its original position and the O position of the limb is fixed on the handle for moving the upper caliper. Upper flange risk

ABOUT

9 (FIG. 1) should coincide with the O position of the lower flange divided by degrees. The M8 nuts of the flange mounting bolts must be released.

The handle 12 of the transverse caliper 13 (Fig. 2) brings the device up to the contact of the probe 8. From the stop 14 (Fig. 1), the indicator scale 7 is set to the O position with the arrow,,. ,

Limbs, scale, risk with divisions are in the initial О position, soft contact of probe 8 with emphasis 14 is provided (Fig. 1). The carriage is rotated from the O position on the lower flange until the risks of the upper flange coincide with the first division of the lower flange::.

On the indicator scale, the arrow is shifted from the O position to the required number of divisions. ..;.; ; ;. . ., -:,.; .;

Turning the upper on the indicator scale: part of the caliper by the required number of divisions to obtain 2 tg s And holding the M8 screws of the flanges 9 and 10 (Fig. 1), the cone is made,,

The use of a device and a method of turning the upper part of the caliper to a given / tg a- improves the quality indicators of the production of products. It allows you to quickly install the upper caliper on a given 1 and while reducing the time for monitoring and adjusting the installation of the upper caliper (see table).
