DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0020] like Figure 1 As shown, the automobile front right corner mold used for clamping and welding in this embodiment includes a main body, a slave body whose top outer side surface is in contact with the bottom inner side surface of the main body, and a Z-shaped connecting member connecting the main body and the slave body; horizontal folded edge positioning surfaces are provided at both ends of the top of the main body, and positioning holes are provided on each of the positioning surfaces at both ends; the cross-section of the slave body is L-shaped, and the bottom of the slave body is a plane with a circular notch in the middle, and positioning holes are provided at each end of the arc-shaped notch; the upper Z-shaped folded edge of the connecting member is provided with two positioning holes, and the lower folded edge is provided with one positioning hole.

[0021] like Figures 2 to 5 As shown, the assembly welding tool of this embodiment includes a base plate 1, which is provided with a support column 1 2 and a support column 2 3 whose tops abut against the positioning surfaces at both ends of the main body, and a support column 3 4 whose tops abut against the folded edge positioning surfaces on the connecting piece, the top of the support column 1 2 is provided with a positioning pin 1 5, the top of the support column 2 3 is provided with a positioning pin 2 6, and the top of the support column 3 4 is provided with a positioning pin 3 7, the base plate 1 is provided with a positioning pin 4 8 and a positioning pin 5 9 matching the positioning holes on the slave piece, the base plate 1 is provided with a pad 10 following the bottom of the slave piece at the positioning pin 4 8, the base plate 1 is also provided with a support column 4 11 supporting the positioning surface at the right end of the main body, and is provided with a pressure clamp 12 corresponding to the support column 4 11 for pressing the slave piece from above, the base plate 1 is provided with a pressure clamp 2 13 for pressing the slave piece and a pressure clamp 3 14 for pressing the connecting piece.

[0022] During operation, first place the main part, and use the positioning pin 1 5 and the positioning pin 2 6 to insert the positioning holes at both ends for positioning, then place the connecting part, and insert the two positioning holes of the upper folding edge of the connecting part into the positioning pin 2 6 and the positioning pin 3 7 respectively, and insert the positioning hole of the lower folding edge into the positioning pin 5 9. In the third step, place the slave part, and insert the positioning pin 4 8 and the positioning pin 5 9 into the positioning holes at both ends of the slave part respectively. In the fourth step, use three pressing pliers to press the workpiece; finally, spot weld and fix the three stamping parts at the interconnected parts.
