Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spring durability detection, in particular to a multi-station spring durability testing device. Background Art
[0002] A spring is a mechanical component that primarily utilizes the elasticity of its material to function. When loaded, it deforms elastically and converts mechanical work or kinetic energy into deformation energy. After unloading, the spring returns to its original shape and converts deformation energy into mechanical work or kinetic energy. After spring production is complete, samples from each batch of products are randomly inspected for durability testing. Currently, durability testing involves repeatedly compressing the spring several times and then checking for cracks or breaks to determine whether the spring meets quality requirements.
[0003] When conducting durability testing on existing springs, the spring is placed on a limit post and a reciprocating compression device is used to allow the spring to continuously expand and contract on the limit post, thereby testing its durability. However, when testing the spring, only one type of spring can be tested at a time. When testing springs of other types, both the limit post and the reciprocating compression device need to be replaced, which greatly affects the test efficiency. Therefore, it is necessary to improve it. Utility Model Content
