AI Technical Summary

Technical Problem

During the welding process of filter press drums, the positioning of angle steel is difficult and posture deviation is prone to occur, resulting in inconsistent welding quality and affecting the dynamic balance performance of the drums.

Method used

A fixed rod and clamping mechanism are used, along with a longitudinal movement component and a centering and pressing mechanism, to ensure that the center extension line of the angle steel wing plate always points to the roller axis. Adaptive clamping is achieved through floating clamps and centering units, and an avoidance component is set to achieve automatic avoidance during the welding process.

Benefits of technology

It improves welding precision and consistency, enhances equipment versatility, increases welding efficiency, and ensures high-quality welding and stable operation of the roller.
