[0041] An automatic welding device for container forklift slots is described in detail below: Step 1: After the previous process is completed, the spot-welded fork slot is transported to the worktable 12. The piston rod of the end positioning cylinder 18 extends, so that one end of the fork slot in the length direction abuts against the piston rod of the end positioning cylinder 18 to achieve positioning, and one side of the fork slot in the width direction abuts against the positioning rod 1101 to achieve lateral positioning. The piston rod of the length adjustment cylinder 19 extends, so that the push plate 191 abuts against the other end of the fork slot in the length direction to achieve positioning. Step 2: Before the work begins, the piston rod of the lifting cylinder 25 pulls the welding gun mechanism, and the transverse linear guide 22 is located above the longitudinal linear guide 24. At this time, the connecting chain 21 pulls the tension spring 26, causing the two welding gun mechanisms to be in a close-to-each-other position. The end of the connecting chain 21 connected to the piston rod of the lifting cylinder 25 is higher than the end connected to the welding gun connecting plate 291. After the fork slots are positioned on the worktable 12, the piston rod of the lifting cylinder 25 extends downward. Under the action of gravity, the transverse linear guide rail 22 drives the welding gun mechanism to move downward along the longitudinal linear guide rail 24 until the fork slot side pressure roller 27 presses against the top surface of the C-shaped plate 02. Then, the piston rod of the lifting cylinder 25 continues to extend downward to loosen the connecting chain 21. Under the action of the tension spring 26, the two welding gun mechanisms move away from each other along the transverse linear guide rail 22, so that the positioning heads 281 in the two fork slots press against the facing sides of the two C-shaped plates 02. During the movement of the automatic welding head 2, under the action of gravity of the transverse linear guide rail 22, the welding gun mechanism and other components, the fork slot side pressure roller 27 always presses against the top surface of the C-shaped plate 02. Under the action of the tension spring 26, the positioning heads 281 in the two fork slots press against the facing sides of the two C-shaped plates 02. At this time, the automatic welding head 2 is in the welding start position, completing the pre-welding preparation. Step 3: Adjust the horizontal and vertical positions of the welding torch 29 through the respective horizontal fine-tuning mechanism 3 and vertical fine-tuning mechanism 4 to adjust the starting point position of the welding torch 29 and ensure that the welding point is located in the optimal position of the weld bead. Step 4: After the preparation work is completed, the welding gun 29 can be jogged to test the welding point and confirm whether the welding point is in the welding position of the weld seam; then the walking motor 14 is started, driving the gear 15 to mesh with the rack 16, and the automatic welding head 2 moves to perform welding. During the welding process, under the gravity of the transverse linear guide rail 22, welding gun mechanism and other components, the fork groove side pressure roller 27 is always pressed on the top surface of the C-shaped plate 02, and the tension spring 26 controls the positioning head 281 in the fork groove to always press against the facing sides of the two C-shaped plates 02. Therefore, it has good adaptability to slight fork groove deformation and can automatically complete the contour welding process of this weld seam. Step 5: After welding is completed, the piston rod of the lifting cylinder 25 retracts, retracting all mechanisms and the welding torch 29. Simultaneously, the travel motor 14 is controlled to move in the opposite direction back to the welding starting point. After the piston rod of the lifting cylinder 25 retracts, the connecting chain 21 moves the transverse linear guide rail 22, welding torch mechanism, and other components upwards along the longitudinal linear guide rail 24 to reset them to their initial state before welding. Then, the piston rods of the end positioning cylinder 18 and length adjustment cylinder 19 reset, and the bottom lifting mechanism lifts the welded fork slot, transporting it to the next station, ready for the next welding operation.

Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the protection scope of the present utility model.
