Spring test device

Abstract

The invention provides a spring test device, and belongs to the technical field of spring test equipment. The spring testing device comprises a test rack, a spring compression fatigue test assembly, aspring tension fatigue test assembly, a spring compression elastic force test assembly, a spring tension elastic force test assembly, and segmented heating sheets, wherein the test rack is divided tofour frames, the spring compression fatigue test assembly, the spring tension fatigue test assembly, the spring compression elastic force test assembly and the spring tension elastic force test assembly are arranged in the four frames of the test rack, respectively, and the segmented heating sheets are arranged between and outside the four frames of the test rack. The spring test device, is not only can quickly complete the elasticity force test and fatigue test of the spring compression and the spring tension, has a short test time and high efficiency, but also can adjust the test temperature, has a reasonable structure, high applicability and good stability.

Description

technical field [0001] The invention relates to the technical field of spring testing equipment, in particular to a spring testing device. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. Generally made of spring steel, the types of springs are complex and diverse. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. According to the nature of the force, the spring can be divided into tension spring, compression spring, torsion spring and bending spring, and can be divided into disc spring, ring spring, plate spring, coil spring, truncated cone scroll spring and torsion bar spring according to the shape. According to the production process, it can be divided into cold coil spring and hot coil spring. Ordinary cylindrical ...

Problems solved by technology

At present, the most common spring testing device on the market is the fatigue testing device, which uses a cylinder to control the pressure plate to move up and down for a long time to test the fatigue strength of the spring. The cylinder stroke of such a fatigue testing device is the spring deformation, because the movement of the cylinder Slow, resulting in a very long fatigue test time, which seriously affects the efficiency of the test

Moreover, many springs are used in special fields such as aerospace and navigation. The working environment of springs is very harsh. To meet the continuous work at high temperature, this requires that the test needs to be tested under the condition of simulating the use environment. The current test equipment does not have this function
