A plurality of bellows grooves 19 are formed inside the transplanting block 9. Two support plates 3 are fixed on the upper surface of the bottom plate 6 by bolts. A laser welding assembly 1 is installed between the two support plates 3. The laser welding assembly 1 can weld the bellows. A fixing frame 2 is fixed on one side of the support plate 3 by bolts. A cylinder 5 is fixed on the outer wall of the bottom of the bottom plate 6 by bolts. One end of the piston rod of the cylinder 5 passes through the bottom plate 6 and is fixed to a carrier plate 8 by bolts. Fixing plates 4 are fixed on both ends of the upper surface of the carrier plate 8 by bolts. Grooves 17 are formed inside the fixing plates 4. Slide plates 18 are welded to both ends of the transplanting block 9, and the slide plates 18 are slidably connected to the grooves 17. By the cooperation of the slide plates 18 and the grooves 17, the transplanting block 9 can move stably, and at the same time, it is convenient for the staff to load and unload materials. Chutes 12 and sliding openings 15 are formed on both sides of the carrier plate 8, and the chutes 12 are communicated with the sliding openings 15. The bellows is placed into the bellows groove 19, and then the transplanting block 9 is pushed, so that the slide plate 18 moves inward along the groove 17 until the slide plate 18 completely enters the sliding opening 15 inside the groove 17. A clamping block 16 is slidably connected to the sliding opening 15, and a wedge-shaped block 11 is slidably connected to the chute 12, and the inclined surface of the wedge-shaped block 11 is in contact with the clamping block 16. Then the cylinder 5 is started, and the cylinder 5 extends to move the carrier plate 8 upward, so that the wedge-shaped block 11 moves upward. At this time, the wedge-shaped block 11 is squeezed by the fixing frame 2, so that the wedge-shaped block 11 moves inward along the chute 12. At this time, the wedge-shaped block 11 squeezes the clamping block 16, so that it moves upward along the sliding opening 15, and the tension spring 14 extends. Furthermore, the clamping block 16 blocks and limits the position of the transplanting block 9, and at this time, the bellows is positioned.

[0023] In the present utility model, it should be noted that a baffle 13 is fixed to the bottom of the clamping block 16 by bolts, and the baffle 13 is slidably connected to the carrier plate 8. When the clamping block 16 moves, the baffle 13 moves with it.

A tension spring 14 is welded to the bottom of the clamping block 16, and the tension spring 14 is fixed to the carrier plate 8, which is convenient for the clamping block 16 to reset. A plurality of balls 10 are rotatably connected to the bottom end of the fixing frame 2, and the balls 10 are in contact with the inclined surface of the wedge-shaped block 11.

Then start the cylinder 5, and the cylinder 5 extends to make the carrier plate 8 move upward, so that the wedge-shaped block 11 moves upward. At this time, the wedge-shaped block 11 is squeezed by the fixing frame 2, so that the wedge-shaped block 11 moves inward along the sliding groove 12. At this time, the wedge-shaped block 11 squeezes the clamping block 16, making it move upward along the sliding port 15, and the tension spring 14 extends. Furthermore, the clamping block 16 blocks and restricts the position of the transplanting block 9. At this time, the diaphragm box is positioned, and then the staff starts the laser welding assembly 1 to weld the diaphragm box.
