Abstract

The invention discloses a torsion spring life testing device comprising a base, wherein a fixed shaft is fixedly arranged on the base, a torsion spring to be tested is sleeved on the fixed shaft, a fixing component is provided on one side of the base to fix a torsion arm of the torsion spring to be tested, and the other torsion arm of the torsion spring to be tested is fixedly disposed on a firstpositioning block; a rotating component is provided on the base and includes a driving source and a turntable, the driving source drives the turntable to rotate, the first positioning block is fixedlydisposed on the turntable and rotates with the turntable, a through hole is opened through the center of the turntable, and the fixed shaft passes through the through hole. The torsion spring life testing device can realize 360-degree torsion test of the torsion spring, and has a wide range of applications.

Description

Technical field [0001] The invention relates to the technical field of torsion spring testing, in particular to a torsion spring life testing device. Background technique [0002] Torsion springs, also called special-shaped springs, are widely used in many fields such as automobiles, chemicals, molds, etc. They are mainly sleeved on the shaft or pin for resetting the shaft or pin. The performance of the torsion spring will directly Affect the service life and quality of the products it uses. Therefore, the life test of the torsion spring must be carried out before the torsion spring is put into use. The service life of a torsion spring is generally expressed as the number of cycles, that is, after a specified number of repeated actions, there will be no surface cracks, breaks, etc. [0003] The common torsion spring life test devices currently on the market have certain restrictions on the rotation angle and the size of the torsion spring, which cannot meet the higher testing req...
