It includes cutting tools / fixtures / molds / measuring tools / inspection tools / auxiliary tools / fitter tools / workstation utensils, etc. Tooling is its general abbreviation. A fixture is also called a jig. Broadly speaking, in any process of the process, a device used to quickly, conveniently, and safely install a workpiece can be called a fixture. For example, welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common and are often simply referred to as fixtures.

[0003] Automobile parts are the various units that make up the overall automotive parts processing and the products serving automotive parts processing. When manufacturing automobile parts, they need to be welded, and when welding automobile parts, fixtures are required to fix the automobile parts, and then welding processing can be carried out.
