AI Technical Summary

Technical Problem

In existing technologies, when performing compression tests on small-diameter, long-length springs, clamping is difficult and stability is poor, which can easily lead to the spring bending or tipping over. Furthermore, existing equipment is expensive and lacks versatility.

Method used

The spring employs a combination structure consisting of a compression fixture body, a guide and limit assembly, and a radial limiter. The guide and limit assembly provides radial support from inside the spring, while the radial limiter restricts spring sway, ensuring the spring's stability during testing.

Benefits of technology

It enables reliable limiting and stability testing of small-diameter, long-length springs, reduces testing costs, improves testing accuracy and efficiency, and is compatible with existing testing equipment without requiring modification of the host equipment.

Abstract

The invention provides a spring compression testing device, and belongs to the technical field of spring testing equipment. The device comprises a compression tool body, a guide limiting assembly and at least one radial limiting piece, the compression tool body is used for being arranged on a lower clamp of test equipment, an axial compression space is formed in the compression tool body, and a limiting structure used for compressing a spring is arranged at the top of the compression space; one end of the limiting assembly is fixedly connected with an upper clamp of the test equipment, and the other end passes through the limiting structure and extends into the compression space for limiting the deformation of the to-be-tested spring in the radial direction; the radial limiting piece is detachably installed on the compression tool body and extends into or penetrates through the compression space, and the part, extending into the compression space, of the radial limiting piece is arranged on one side of the guide limiting assembly and used for limiting shaking of a to-be-tested spring arranged on the guide limiting assembly in the radial direction. The device is mainly used for solving the technical problems that in the prior art, clamping is difficult, stability is poor, and spring bending is easily caused when a compression test is carried out on a small-diameter and long-size spring.
