Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of torque detection equipment, in particular to a torque detection mechanism. Background Art
[0002] Torque test is a test method used to test the torsion resistance of an object when subjected to twisting or rotational forces. Torque test is widely used in various industries, such as automobile manufacturing, aerospace, machinery manufacturing and other fields.
[0003] First of all, the standard of torque test is crucial to ensure product quality and safety. In the automobile manufacturing industry, torque test can be used to detect the torsion resistance of automobile parts to ensure that the car will not have safety problems such as steering loss of control during driving. In the aerospace field, torque test can be used to test the torsion performance of aircraft engine parts to ensure that there will be no parts breakage during flight, thereby ensuring flight safety. Therefore, the standard of torque test is of great significance to ensure product quality and safety.
[0004] Currently, torque tests are all performed using separate measuring equipment. When a product needs to be tested for torque, the product needs to be placed separately on a torque testing machine for measurement. However, the entire torque testing machine is expensive and has high operating costs. Therefore, our company has developed a torque detection mechanism that is used in conjunction with a lathe to save costs. Utility Model Content
