A spring testing system and method

Abstract

The invention relates to a spring testing system and method and belongs to the technical field of spring testing. The system comprises a conveying device, wherein end positioning devices, direction recognizing devices, testing devices, a color code printing device and an outlet control device are sequentially arranged on the conveying device in the conveying direction, the conveying device, the end positioning devices, the direction recognizing devices, the testing devices, the color code printing device and the outlet control device are all electrically connected with the control device. The system and the method have the advantages that continuous automation of spring production and testing can be realized, the positioning and direction recognizing are accurate, the test result is accurate, and springs can be automatically sorted and marked according to the testing result.

Description

technical field [0001] The invention relates to a spring testing system and method, which belongs to the technical field of spring testing, and is especially suitable for carrying out load testing on springs. Background technique [0002] Spring is a kind of elastic element widely used in mechanical and electronic industries. The spring can produce large elastic deformation when it is loaded, and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to its original shape. Deformation energy is converted into mechanical work or kinetic energy. Since the spring is in a working environment with changing loads for a long time, the manufacturer needs to conduct strict factory tests on the spring. At present, in spring manufacturers, spring production equipment and testing equipment are usually separated independently, that is, when performing performance tests on springs, the spring can only be ma...

AI Technical Summary

Problems solved by technology

At present, in spring manufacturers, spring production equipment and testing equipment are usually separated independently, that is, when performing performance tests on springs, the spring can only be manually moved from the production equipment to the testing equipment. The existing problems are: 1. Manually transport the spring back and forth between the production equipment and the testing equipment, the production efficiency is low and the amount of manual operation is large; 2. After manually placing the spring on the testing equipment, the spring needs to be repositioned, which increases the working time At the same time, it is also prone to the problem of inaccurate test results caused by inaccurate manual positioning; 3. After the spring test is completed, the operator will place the qualified or unqualified springs separately according to the test results, and rely on manual classification management, which leads to low work efficiency. and prone to placement errors
