Problems solved by technology

[0003] The product to be tested includes a product body. There is a cover on the body. There is a torsion spring between the cover and the body. When the cover is closed with the body, the cover is caught by the hook on the side of the body. When the hook is opened, the torsion spring will drive the upper cover to open. It can be seen that the torsion spring is very important for the performance of the product to be tested, so it is very necessary for the service life test of the torsion spring. There is no relevant device to test the service life of the torsion spring

Abstract

The invention discloses a device for testing the service life of a torsional spring. The device for testing the service life of the torsional spring comprises a base, wherein a quick-action cylinder and a slow-action cylinder are arranged at the two ends of the base respectively, the quick-action cylinder is fixedly arranged on the base and is provided with a pivot mechanism which abuts against a clamping hook of a product to be tested, and the slow-action cylinder is fixedly arranged on the base and is provided with a gear mechanism which can overturn an upper cover of the product to be tested. The device can test the service life of the torisional spring fast and conveniently.

Description

technical field [0001] The invention relates to a test device, in particular to a torsion spring service life test device. Background technique [0002] At present, torsion springs are widely used in the fields of automobiles, chemicals, abrasive tools, etc. The performance of torsion springs directly affects the performance and quality of their products. The performance of the torsion spring is mainly determined by the following parameters: the diameter of the torsion spring steel wire, the diameter of the torsion spring, the pitch of the torsion spring, the material of the torsion spring, etc. In the process of use, the torsion spring needs to bear random load force, and finally fails after experiencing several cyclic stress changes. [0003] The product to be tested includes a product body. There is a cover on the body. There is a torsion spring between the cover and the body. When the cover is closed with the body, the cover is caught by the hook on the side of the body...
