[0002] In the manufacturing process of new energy battery boxes, multiple parts typically need to be welded, such as L-shaped brackets, Z-shaped brackets, water nozzles, and support blocks. These parts have complex structures and require precise spatial positioning. Traditional welding methods, which often involve manual positioning and spot welding one by one, present the following problems:

[0050] In specific implementation, the operation process of this invention is as follows: The workpiece body is placed on the welding platform and positioned by the positioning component 18 and the side stop component 17 located on the welding platform. The cylinders of the pressing component 13 and the top pressing component 14 are activated to press the workpiece body. The first three-axis guide rod cylinder 311, the second three-axis guide rod cylinder 68, and the third three-axis guide rod cylinder 715 are activated to push out. Small parts such as L-shaped brackets, Z-shaped brackets, water nozzles, and support blocks are placed and positioned by positioning pins. After placement, the cylinders (first cylinder 34, second cylinder 413, third cylinder 514, fourth cylinder 716, etc.) are activated to press. Small parts are welded. After welding is completed, the cylinders are reset and the finished workpiece is taken out.

[0051] Welding positioning of the L-shaped bracket: The first three-axis guide cylinder 311 is activated, driving the first connecting plate 37 and all its components to rise. The L-shaped bracket 17 is placed in the L-shaped bracket placement slot 362 of the positioning block 36. Precise positioning is achieved by inserting the positioning pin on the positioning block 36 into the positioning hole of the L-shaped bracket 17, ensuring precise positioning. The side of the L-shaped bracket 17 contacts the first plunger 315. The first cylinder 34 is activated, pushing the first pressure head 31 downwards, firmly pressing the L-shaped bracket onto the positioning block 36, completing the clamping process, and welding can then begin. The working process of the second L-shaped bracket welding assembly 8, the third L-shaped bracket welding assembly 12, and the fourth L-shaped bracket welding assembly 16 is the same.

[0052] Welding and positioning of the first water nozzle: The water nozzle is fitted onto the first positioning pin 42. The second cylinder 413 is vented. The fourth connecting plate 47 is pushed by manually moving the lever 44, achieving pre-tightening with good flexibility. Activating the second cylinder 413 moves the fourth connecting plate 47 along the first guide rail 414. The stop block 411 abuts against the side of the fourth connecting plate 47, ensuring accurate positioning at the end of the stroke.

[0053] Welding and positioning of the second water nozzle: In the venting state of the third cylinder 514, the water nozzle is pre-pressed by manually operating the connecting rod 57. The third cylinder 514 is activated, driving the fifth connecting plate 55 to move along the second guide rail 515. The limit block 511 limits the movement stroke of the fifth connecting plate 55.

[0054] Welding and positioning of the support block: The first support block welding assembly 6 drives the entire positioning unit to move via the second three-axis guide rod cylinder 68. The support block 20 is placed on the workpiece body and positioned by the third positioning pin 61. The U-shaped third positioning pin seat 62 and its auxiliary positioning protrusion 621 can well wrap and position the support block, ensuring its accurate welding position.

[0055] Welding and positioning of the Z-type bracket: The working process of the first Z-type bracket welding assembly 7 is similar to that of the L-type bracket assembly. The Z-type bracket is placed on the fourth positioning pin seat 74, and the holes on it correspond to the fourth positioning pin 73 and the fifth positioning pin. The upper surface of the fourth positioning pin 73 and the bracket placement platform 743 form a multi-step structure, perfectly fitting the complex shape of the Z-type bracket. The third three-axis guide rod cylinder 715 drives the receiving plate 79 to rise, the fourth cylinder 716 drives the second pressure head 71 to press down, and at the same time, the second plunger 717 provides lateral positioning, thereby firmly pressing the Z-type bracket. The working process of the second Z-type bracket welding assembly 9 is the same.
