They are usually made of high-strength, high-corrosion-resistant stainless steel materials. They can effectively improve the reliability and service life of threaded connections. In the automotive industry, automotive sockets are widely used.

[0003] Therefore, the automated installation technology of automotive braces is also very important among the various technologies in the automotive industry. However, in the existing installation methods or equipment, only real-time parameter identification and control are performed during the screw-in installation process of the braces, and it is impossible to analyze the links before and after installation. That is, the existing technology is unable to detect, match and control the entire process of braces installation, which leads to insufficient installation quality and efficiency, and ultimately leads to insufficient safety performance of automotive components.

If so, exclude the positions of the completed holes and the hole position information of the abnormal holes based on the installation hole information of the current component, and use the remaining hole position information as the missing hole positions.
