AI Technical Summary
Existing welding fixtures cannot readjust the position when positioning and clamping workpieces, resulting in low operating efficiency.
A welding fixture for aerospace sheet metal parts, comprising a base plate, a rotating carrier plate, and an adjusting frame, is designed. By extending and retracting the adjusting frame and deflecting the rotating carrier plate, the workpiece can be accurately positioned and reliably clamped, allowing for angle adjustment after fixing.
This achieves stability in workpiece welding and simplifies operation, thereby improving welding efficiency.
