AI Technical Summary
Traditional welding positioning fixtures lack sufficient stability for flipping and have no effective locking mechanism, which makes the workpiece prone to displacement under external force or vibration, affecting welding quality and posing safety hazards.
A positioning fixture including a clamping and positioning mechanism and a locking mechanism was designed. The clamping and positioning mechanism provides radial initial positioning, the locking mechanism restricts the rotation of the shaft, and the universal wheels enable stable flipping and angle adjustment of the workpiece.
It improves the stability of workpiece flipping, avoids displacement caused by external force or vibration, ensures welding quality, and reduces safety hazards.
