AI Technical Summary
Existing welding fixtures can only be used for one welding process, resulting in high investment costs and large production space occupation. In particular, in automobile manufacturing, the repair welding of the chassis assembly and the welding of the guardrail and the chassis assembly with welded steel plates require two sets of fixtures, which increases equipment and space costs.
A welding fixture was designed, comprising an X-axis positioning clamping assembly, a Y-axis positioning clamping assembly, a Z-axis support assembly, and a Z-axis clamping assembly. Through the adjustable height support of the anti-deformation positioning block, a single fixture can be used for the repair welding of the underframe assembly and the welding of the guardrail to the underframe assembly, preventing deformation of the underframe assembly.
It reduces equipment costs and production space requirements, enables the continuous completion of multiple processes, and reduces equipment investment and space requirements.
