[0040] During specific implementation, this application mainly realizes the welding clamping and positioning of battery box body accessories (including bushings 12, brackets 13, and sealing plates 14), including bushing welding tooling, bracket welding tooling, and sealing plate welding tooling 6. The battery box body 11 is placed on the installation platform 2 and limited by L-shaped workpiece stop blocks 15 distributed around the support plate assembly 4. An installation seat 111 is provided on the outer side of the battery box body 11, and a number of installation holes are provided on the installation seat 111. The bushings 12 are placed in the installation holes. The bushings 12 are pressed by the pressing heads of the rotary pressing assembly A5, the rotary pressing assembly B10, and the strong pressing assembly 3 above. A first support block 52 is provided below the bushings 12, and the bushings are clamped through the pressing assembly and the support block; the pressing head of the rotary pressing assembly A5 is a straight-arm pressing head, and the pressing head of the rotary pressing assembly B10 is a Z-shaped arm pressing head. A bushing positioning assembly 9 is further provided below the rotary pressing assembly B10 at a corner of the workpiece to position the bushings 12; the bushings 12 at the front and rear symmetric positions on the right side of the workpiece are clamped by the strong pressing assembly 3 and the second support block 33. A spring 355 is provided at the front end of the pressing head assembly 35. Through the combined action of the second pressing cylinder 31 and the spring 355, the pressing force is stable and reliable.

[0041] The welding position of the bracket 13 is on the outer side of the battery box body 11. The bracket welding tooling uses a bracket side pressing mechanism 7 and a bracket tightening mechanism 8 for pressing and positioning. The tightening cylinder 81 acts, driving the L seat 85 thereon to contact the lower surface of the battery box body 11. The bottom edge of the bracket 13 is arranged on the supporting block 86, limited by the protruding part of the supporting block 86 on one side and limited by the first stop block 87 on the other side, as Figure 4 shown. In order to prevent the bracket 13 from being deformed by directly operating the second side pressing cylinder 72, when the second side pressing cylinder 72 is in a state of oil leakage, first manually pull the handle 75. The handle 75 drives the transition plate 76 and a set or two sets of pressing components 77 thereon to move, pushing the pressing block 774 to one side of the bracket 13 for pre-pressing. Then the PLC controls the second side pressing cylinder 72 to act to press the bracket 13. A second spring is sleeved on the pressing block 774. Under the action of the spring force, the bracket 13 can be better pressed without displacement and without damaging the workpiece.

[0042] When welding the sealing plate 14 on the side of the mounting seat 111 of the battery box body 11, first manually place the sealing plate 14 in place. The lower side is limited by the Z-shaped supporting block 614. Similarly, in order to prevent the sealing plate 14 from being deformed by directly operating the side pressing cylinder 61, when the side pressing cylinder 61 is in a state of oil leakage, first manually pull the fork 610. The fork 610 drives the second connecting block 612, the first connecting block 65 and the 7-shaped positioning block 68 thereon to move, making the 7-shaped positioning block 68 approach the sealing plate 14 for pre-pressing. Then the PLC controls the side pressing cylinder 61 to act to press the sealing plate 14.

[0043] The bushing welding tooling, the bracket welding tooling, and the sealing plate welding tooling stably support, position, and clamp the battery box body accessories (bushings, brackets, sealing plates), enhancing the stability and accuracy of the welding connection, ensuring the uniformity and consistency of the welding, improving the overall quality of the welding, and improving the efficiency of the welding process.
