Description

Technical Field

[0001] The utility model belongs to the technical field of springs, in particular to a spring tension and compression testing machine. Background Art

[0002] As an important component in industrial systems, springs are used in large quantities and come in many varieties. During the production process of springs, the springs need to be tested for performance in order to check whether the performance of the springs meets the requirements. The spring tension and compression testing machine is a special instrument for testing the deformation and load relationship characteristics of tensile and compression springs. The sensor inputs the tension or pressure value of the spring monitored when it is stretched or compressed to the deformation amount into the computer, and the computer is used to calculate the elastic coefficient of the spring. The tension and compression fixture is used to apply pressure to the spring to deform the spring and generate elastic force, and then the measuring mechanism is used to measure the elastic force of the spring.

[0003] During the test, the spring needs to be hung between hooks. The spring may break when stretched. The broken spring may cause injuries to the staff. Therefore, we provide a spring tension and compression testing machine to solve the above problems. Utility Model Content
