AI Technical Summary
The current welding process for the crossbeams and longitudinal arms of automotive frames relies on manual experience, resulting in low positioning accuracy and efficiency. The overall positioning of the tooling is inaccurate, affecting welding quality and dimensional consistency. Furthermore, the existing tooling lacks versatility and is difficult to adapt to the welding requirements of different vehicle models or specifications.
A flexible welding system with a beam and longitudinal arm is adopted, including a welding robot and a positioning frame. The positioning frame is equipped with limiting components and fixing mechanisms. The beam and longitudinal arm are flexibly supported and limited by the support and fixing mechanisms. The positioning frame is driven to rotate by a motor and a reducer, and multi-angle welding is achieved in conjunction with the guide rail.
It improves welding precision and efficiency, enhances system adaptability, can adapt to welding requirements of different vehicle models and specifications, reduces human error, and improves welding quality and dimensional consistency.
