(54) SEMI-AUTOMATIC FOR CONTROL OF INSIDE DIAMETER OF COMPRESSION SPRINGS

t

The invention relates to mechanical engineering and can be used to control the internal diameter or non-cylindrical nature of compression springs.

The closest to the technical essence of the invention is a semi-automatic machine for controlling the internal diameter of the compression springs, comprising a housing, a sleeve vertically fixed on it with an upper base end, placed in the sleeve with axial displacement, a gauge spring-loaded along the axis of the sleeve, an interacting cam mechanism with it and coaxially with the caliber installed linear displacement sensor 1.

In the known semi-automatic device, the linear displacement sensor acts on the controlled spring when the caliber is moved and causes the springs to be forced on the caliber, which reduces the control accuracy.

The purpose of the invention is to improve the accuracy of control.

This goal is achieved by the fact that the semiautomatic device for controlling the internal diameter of the compression springs is equipped with an adjustable stop mounted on the body parallel to the caliber.

hinged on the body perpendicular to the caliber two-arm with a bracket on one shoulder, which interacts with an adjustable stop and is spring-loaded relative to

it, and the end of the other lever arm is located between the sensor and the caliber, and the one installed between the two-arm lever and the base hub of the hub on

10 bracket with the ability to move perpendicular to the axis of the gauge rod.

The drawing shows a semi-automatic circuit for controlling the internal diameter of the compression springs.

The semiautomatic device includes a housing 1, a sleeve 2 mounted vertically on it with an upper base end, placed in sleeve 2 caliber 3, spring-loaded with the help of spring 4, cam mechanism 5 with electric drive b, 7 sensor, linear displacement, adjustable stop 8, hinged

25 on the housing 1 of the double-arm lever 9 with the bracket 10, the spring 11 mounted on the bracket 10 with the possibility of axial movement of the rod 12 and the controlled spring 13.

thirty

Semiautomatic works as follows.

In the initial state, the cam mechanism 5 holds the caliber 3 in the lowermost position, and the controlled spring 13 is installed on the base end of the sleeve 2, the double-arm lever 9 is fixed by the support 11 by means of the spring 8 so that between the rod 12 and the caliber 3 and between the bar 7 linear displacements and the corresponding shoulder of the two shoulders lever 9 form normalized clearances. When measuring, the cam mechanism 5 moves the caliber 3 inside the hub 2. In this case, the spring 13, diameter of which is larger than the diameter gauge 3, is controlled ennogo weight slides on. caliber 3 and maintains contact with the base end of sleeve 2. As it moves, gauge 3 rests on the lever arm 9 and rotates it until rod 12 rests on controlled spring 13. This further movement of gauge 3 stops and the spring compresses 4. The sensor 7 linear displacements is not operative, thaws and the controlled spring will be referred to the appropriate group, shelf life. If the inner diameter of the controlled spring 13 is smaller than the caliber 3 diggmeter, then when the latter moves, the spring 13 will hang in the upper part of the caliber 3 and lift 51 above the base of the sleeve 2. The rod 12 will move further to the caliber 3, and the linear displacement sensor 7 will trigger and spring 13 will be assigned to another shelf life group.

The proposed semiautomatic device has a simple design, increases the reliability and accuracy of control.
