The chucks are mainly divided into ER chucks, tire chucks, air chucks, pneumatic chucks, spring chucks, etc. With the continuous rise of the small processing industry, the quality and precision of processing are undoubtedly the biggest competitors at present. The functionalization and quality of the chuck also have different requirements. The main functions of the chuck are reflected in the following points:
1. Control the movement of machinery. Such as valve springs in internal combustion engines, control springs in clutches, etc.
2. Absorb vibration and shock energy. Such as buffer springs under automobiles and train cars, vibration-absorbing springs in couplings, etc.
3. Store and output energy as power. Such as clock springs, springs in firearms, etc.
Fourth, as a force measuring element. Such as dynamometers, springs in spring balances, etc. The ratio of the load to the deformation of the spring is called the spring stiffness, and the higher the stiffness, the stiffer the spring.
