AI Technical Summary

Technical Problem

The existing fixed tooling tables in vacuum pump assembly lines are difficult to change, the positioning accuracy depends on the operator's experience, and there is a lack of automation interfaces, resulting in low production efficiency and poor assembly consistency.

Method used

The modular multi-degree-of-freedom positioning fixture plate is adopted. Through the combination design of support blocks, support plates and support columns, the rotation and translation degrees of freedom of the vacuum pump are restricted. Combined with the pin holes on the base plate, it can achieve quick changeover and high-precision positioning.

Benefits of technology

It enabled rapid model changeover, improved production efficiency and assembly quality, reduced labor intensity, and enhanced product stability.
