Description

one

The invention relates to measuring instruments.

A caliper is known that contains a rod and is mounted with two movable jaws. However, using such calipers, it is impossible to precisely set the distance between moving elements, for example, between the wheels of a pair of wheels during formation.

The proposed caliper provides the ability to set the exact distance between moving parts.

This is achieved by the fact that each sponge is spring-loaded and has a guide, a plate located in the latter with an emphasis and a micrometric screw connected to it, and at each end of the rod there is a sleeve that carries a microswitch interacting with the emphasis.

FIG. 1 depicts the described caliper, the & tions, view; FIG. 2 is a view along arrow A of FIG. one; in fig. 3 section bb in fig. 2

The caliper consists of a rod I made in the form of a pipe, with a main scale, at the ends of which there are two measuring sponges 2. To move the sponge, followed by a moving surface is a spring 3, which is tensioned using a nut 4

and counter ayki 5 located on the threaded part of the spring guide 6. The sponge is fixed in the desired position on the tanga by screw 7.

At each end of the rod using the sleeve 8 is installed sensor 9, made in the form of a microswitch, the pusher which interacts with the stop 10 when the sponge 2 reaches a certain size. To set a certain size, the stop 10 is mounted on the plate 11, which can move the guide along the guides 12 located on the measuring sponge 2 using a micromometric screw. 13. For alternately switching the sensors into operation in the middle part of the caliper, a switch 14 is located. The sensors are connected to the external circuit by means of | Plug connector 15.

Working with a caliper when repressing a wheel pair is performed as follows.

Both measuring jaws 2 are set to zero division and one of them is fixed with screw 7. Switch 14 turns on the sensor {mounted on the opposite side of the fixed jaw. Then, install the caliper between the wheels of the wheelset and by turning on the press, shift the wheel from the side of the included sensor. Moving the wheel, the measuring sponge 2 blinks to the required Mc} F5 size, when reached, the stop 10 presses the sensor 9 pusher and turns off the press drive.

Since it takes some time from the moment the sensor responds to stopping the press drive, the shear wheel will stop with some error. In order for ycTpii. To clarify this error, it is necessary to shift the emphasis 10 with the help of a micro-curtain screw 13 by the value obtained

LOSS,

After the wheel has been shifted to a certain size, it is necessary to fix the moving measuring sponge, and release the previously fixed sponge.

Turning on the sensor released sponge

the second wheel is repainted in the same way as the first.

Formula

inventions

A caliper containing a rod and movable jaws installed by it, is distinguished by the fact that it is possible to establish an exact distance between the moving elements, each sponge is spring-loaded and has a guide located in the latter plate with an emphasis and a micrometric screw connected with it, and A bushing is mounted on each end of the rod, carrying a microswitch that interacts with the Stop.
