AI Technical Summary

Technical Problem

The existing vehicle assembly welding device does not have an anti-welding structure, which causes the missing welding to be discovered only after the welding is completed. It needs to be reworked for repair welding, which affects product quality. Repair welding after missing welding is time-consuming and labor-intensive, reducing production efficiency.

Method used

A leak-proof welding device for parts for assembly welding of the whole vehicle is designed, including a leak-proof welding mechanism and a positioning mechanism. The anti-missile welding mechanism detects the integrity of the welding point through the inspection pin rod and pressure sensor, and promptly reminds the staff of the missing welding situation; the positioning mechanism achieves efficient, precise positioning and clamping of parts through racks and extruded rotating blocks.

Benefits of technology

Through the detection of the leakage-proof welding mechanism and the precise positioning of the positioning mechanism, it is possible to conduct inspections while welding, and timely discover missing welding problems, reduce rework frequency and maintenance time, improve production efficiency, and ensure welding quality.
