AI Technical Summary
Traditional muffler welding fixtures cannot effectively limit the left and right movement of the partition, causing the partition to easily move left and right during the welding process, which affects the welding quality.
A silencer welding fixture including a base and a clamping assembly is designed. The clamping assembly consists of a movable seat, a baffle, a threaded sleeve, a bidirectional screw, and a movable component. By adjusting the position of the movable seat and rotating the bidirectional screw, the baffle clamps the partition, preventing it from moving left or right.
This ensures that the partition does not shake or shift during the welding process, thus guaranteeing the stability and quality of the welding.
