What is the function of the chuck, what does the chuck mean?

In the modern complex manufacturing environment, most factories have undergone rigorous training and carefully learned the processing and motion principles, architectural characteristics and use skills of some new equipment, which is the only way to facilitate operation. Especially for some high-end technical systems, such as many machine tools will be applied to the chuck, it is elastic, so it is also called elastic chuck, is a kind of fixture used to fix some parts. Its types can also be divided into many categories, such as pneumatic chucks, common spring chucks, clamping chucks, etc.

Although it is very small, it plays a great role in mechanical movement, such as the valve springs inside some machines, and the control springs in the clutch of automobiles, which can control the movement of machinery. In addition, there are buffer springs, which are found in some devices that generate force due to movement, and its function is to absorb the energy of vibrations and impacts. In some of the more delicate mechanical objects, the clock spring can store and convert the output energy into power.

The current era is also a mechanical era, and the processing and manufacturing of various machinery are more and more out of the original limitations, more novel and effective.

Control the movement of machinery, such as valve springs in internal combustion engines, control springs in clutches, etc.

Absorbs vibration and shock energy, such as buffer springs under automobiles, train cars, vibration-absorbing springs in couplings, etc.

Stores and outputs energy as power, such as clock springs, springs in firearms, etc.

Used as a force measuring element, such as a force tester, a spring in a spring scale, etc. The ratio of the load to the deformation of the spring is called the spring stiffness, and the greater the stiffness, the stiffer the spring.
