Automobile inspection fixtures are equipment or tools used to control the size of auto parts and the vehicle, as well as the matching degree between parts, and are known as "auto referees". Automobile inspection fixtures are equivalent to third-party certification tools for auto parts companies and vehicle manufacturers. After the initial production of auto parts is completed, they are put on special automobile inspection fixtures for inspection, and the parts that pass the inspection can enter the next one. In the production process, otherwise, it is necessary to improve the processing of auto parts until they fully meet the design requirements, so as to ensure the smooth flow of the entire production line. Therefore, auto inspection tools can improve the processing accuracy and production efficiency of auto parts companies and vehicle manufacturers, and effectively solve problems such as the coordination between auto parts and the design fit of the entire vehicle.

　　In the automotive industry, inspection tools can be divided into single-piece inspection tools, assembly inspection tools, opening and closing parts inspection tools, assembly inspection tools, and integrated interior and exterior inspection tools according to their use stages.

　　From the point of view of actual use, the automobile inspection tools currently used by auto parts companies are generally divided into two categories: one is inspection tools with measurement functions; the other is three-coordinate measurement brackets, also known as flexible inspection tools. Among them, flexible automobile inspection fixtures have some special advantages that traditional automobile inspection fixtures do not have, mainly including: a flexible inspection fixture can measure different products with a slight adjustment (one-to-many or adjustable, save storage space, and parts can be reused ), convenient modification and positioning, automatic measurement, automatic data recording, high measurement accuracy, no fear of deformation (low maintenance cost), short development cycle, etc.
