In fact, there is no exact definition of clamping fixture. Personally, I think it is an auxiliary device specially made to solve practical problems or realize a certain function.

It is characterized by simple structure, wide application and various types. It can be a piece of iron or a piece of equipment. For example, the stopper for grinding machine can be called a clamping jig. For example, the Hi-pot tester can be called a jig. (Note: The noun comes from Japan and China is called fixture)

Clamping tools have been widely used long before the industrial era, including mechanical tools, woodworking tools, welding tools, jewelry tools, and other fields. Some types of jigs are also called "moulds" or "auxiliary tools", the main purpose of which is to repeat some parts repeatedly and accurately.

For example, an obvious example is that when copying a key, the original key is usually fixed on a jig, so that the machine can copy a new key under the guidance of the appearance of the original key.

Clamping tools are widely used in many industries, such as electronics: basically, it can be affirmed that where there is an electronics factory, there will be clamping tools; Where there is no electronics factory, clamping tools are everywhere.

Application of clamping fixture in electronic industry: roughly classified as press-in fixture, bending fixture, cutting fixture, riveting fixture, welding fixture, testing fixture, fixing fixture, etc. Of course, it can also be divided into ordinary and special categories.

The application of clamping fixture in the production industry: for example, testing fixture, which is specially used to test and test the function, power calibration, service life and performance of products. Because it is mainly used for testing various indexes of products on the production line, it is called a testing jig.
