AI Technical Summary

Technical Problem

When processing rollers of different diameters, the existing automatic welding device for rollers requires multiple measurements of the coaxiality of the clamp and cylinder. The operation is complicated and the error is large, resulting in a decrease in production efficiency and product quality.

Method used

An automatic welding device including vertical positioning members and transverse positioning members is designed. Through the rotation and movement functions of the transverse positioning members, the bearing seat can be quickly fixed to the cylinder without repeated measurement of coaxiality. Through the coordination of the pushing component and the jet assembly, the cylinder is accurately positioned at the welding position and the formation of protective gas laminar flow.

Benefits of technology

It is realized that when processing rollers of different diameters, the coaxial state of the cylinder and bearing seat can be quickly achieved, which simplifies operation, reduces errors, and improves welding quality and production efficiency.
