In the manufacturing and processing of automotive inspection fixture, to ensure the quality of parts, and improve productivity and accuracy, the fixture testing design scheme must be rigorous and effective, adopt a reasonable inspection fixture structure, select the correct materials and heat treatment methods, and be guaranteed by advanced inspection fixture manufacturing technology. To economically, efficiently, and accurately process automotive fixture testing and meet environmental requirements, ensuring that parts are pollution-free, energy-efficient, and easy to scrap, recycle, and reuse during manufacturing and use. The manufacturing of inspection fixture by inspection fixture manufacturers should meet the following basic requirements.

1. When designing and manufacturing automotive inspection fixture, comprehensive consideration should be given to the actual situation, and more suitable manufacturing methods should be selected to improve accuracy, maximize production efficiency, and reduce fixture testing costs. The dimensional accuracy of products with high manufacturing precision largely relies on the accuracy and surface quality of the checking fixture as the basis for analysis and judgment. Therefore, to produce qualified products, the designed and manufactured inspection fixture must have high precision. Strictly speaking, the precision of the working part of the inspection fixture is usually 1/10 of the product precision. The accuracy of the measuring tool will vary with the precision requirements of the product. The higher the precision of the inspection fixture, the better it can detect products with higher precision requirements.
2. Short manufacturing cycle. The acceleration of new product updates and the increasingly fierce market competition require shorter manufacturing cycles for inspection fixture. The manufacturing cycle of checking fixture is generally determined by the level of automobile inspection tool manufacturing and production management. Manufacturers should try to shorten the fixture manufacturing cycle as much as possible, but also ensure product quality, meet high standard requirements, and improve product competitiveness.
3. Long usage time. For automotive inspection fixture or inspection fixture for thermoformed products that undergo full process inspection, the frequent use of inspection fixture is influenced by the situation and surrounding environment. The wear of automotive inspection fixture parts is significant, and therefore, the length of their service life will directly affect on-site production efficiency and benefits. Most modern inspection fixtures adopt a modular assembly mode for batch production of standard parts, and the design and manufacturing use a large number of standard parts to shorten the manufacturing cycle. Therefore, batch production of standard parts is necessary to improve production efficiency.

Automotive inspection fixture is an essential fixture in the automotive manufacturing industry. The measuring tool is used to check the accuracy of the parts, and it should have sufficient accuracy. Although there are many varieties of them, technicians need to be proficient in the use of different types of inspection fixture, each with different performance. Therefore, operators choose the type of inspection fixture according to the required requirements to improve the quality and efficiency of detection and repair.
