SU39405A1 - Limiting bracket - Google Patents

Description

Among the measuring tools in the factory technique, the limit brackets are found, in which ball measuring sponges are used, which are set to the required size. According to the invention, in a similar measuring clamp, one of the jaws is provided inside with a adjustable stop, settable from the stop in contact with the ball, for a distance corresponding to the tolerance.

The drawing shows the proposed limiting bracket with a partial size.

The proposed limiting bracket consists of the usual body bent in the form of a bracket /, provided with measuring jaws at the ends. Each sponge consists of a screw-in end of the body 7 of the sleeve 2 screwed into the holes, carrying the ball 3, pressed, under the action of the spring 4, with a guide stop 5; in the same sleeve 2, another mounting stop 6 is screwed in, which presses the spring 4 and is held in position by a screw 9. To prevent the sleeve 2 from moving, a stop screw 7 serves; on the outside, the sleeve 2 is closed by a cap 5 screwed onto it.

Sponge-limit staples can be installed on the passage and impassable dimensions. The balls of the 3 jaws are measured at their extreme points.

In each case, the bracket can be installed on the desired size, close to each other. The jaws are installed using a sleeve 2, the position of which is fixed by means of a cap 6 and a set screw 6.

When measuring, for example, a part size of 35 + 0.05, Ioganns tiles are taken at 34.95 and the jaws of the bracket are set to this size with the aid of sleeve 2, and in this position the spring 4 must be in a compressed state, i.e. The end faces of the mounting 6 and the guide 5 stops will come into contact. In this position, the sleeve 2 is locked by the screw 7. Then the Johansson tiles are taken to 35.05, the mounting stop B is moved away from the guide stop 5 to the position at which these tiles pass between the jaws of the bracket; the spring 4 diverges and the gap a between the end sides of the stops 5, 6 will be equal to 0.1. After this installation, the locking screw 9 is screwed on and the sponge is closed with a cap 8. Thus, the bracket is adjusted to size 35 + 0.05.

When measuring, the bracket is placed on a cylindrical roller with a diameter of 33 + 0.05 without the effort of a hand, only under its own weight; at the same time the bracket should not pass;

it is only when the spring 4 is pressed that the compression and guide stops stop converge and the clamp passes.

The subject matter of the invention.

A limiting bracket with ball measuring jaws adjustable for a certain size, characterized in that one of the jaws is provided inside with a mounting stop b, which is installed from the guide rest 5 with the ball for a distance corresponding to the tolerance.
