Technical Field
[0001] This utility model relates to the technical field of stone hammer processing equipment, and in particular to an integrated mechanism for high-precision pressing, positioning and detection of stone hammers. Background Technology
[0002] Car stone impact protection strips are protective strips that can be installed on the bottom of a car. They can effectively prevent the bottom of the car and the lower edges of the doors from being hit by gravel and mud during driving, which can easily scratch the bottom of the car and the lower edges of the doors, thus causing damage to the car itself.
[0003] Existing automotive stone hammer strips require spot welding of multiple stone hammer strips. During spot welding, multiple stone hammer strips need to be fixed and stabilized using clamps so that they fit together before welding. However, when multiple stone hammer strips to be welded are pressed together, the pressing position is not easy to adjust, resulting in a lot of time being spent adjusting the fit position between the multiple stone hammer strips.
[0004] Therefore, there is an urgent need to provide a high-precision pressing, positioning, and detection integrated mechanism for stone impact bars to solve the above problems. Utility Model Content
