The muffler to be processed is placed in one of the positioning plates 26, and then the first cylinder 23 is started. The output end of the first cylinder 23 drives the connecting block 21 to move, and at the same time, the guide groove 22 plays a role in facilitating the movement of the connecting block 21. The movement of the connecting block 21 drives the movement of the first connecting rod 27, and the movement of the first connecting rod 27 drives the movement of the muffler 21. The first tooth plate 28 moves, and the movement of the first tooth plate 28 drives the gear 201 to rotate. The rotation of the gear 201 drives the second tooth plate 206 to move.

The first vertical rod 32 moves back and forth to drive the moving frame 36 to move up and down. The moving frame 36 moves up and down and cooperates with the lever 37 to make the disc 38 rotate. The rotation of the disc 38 drives the connecting piece 301 to rotate through the round rod 39. At the same time, the slot 302 facilitates the positioning of the connecting piece 301. The rotation of the connecting piece 301 drives the shell 5 to rotate, so that the positioned muffler is turned over to facilitate the welding process of the muffler.

[0021] The two positioning plates 26 are distributed in a mirror image, and both positioning plates 26 are arc-shaped, so that the positioning effect of the two positioning plates 26 is better.

[0022] Two positioning grooves 207 are provided on the inner walls on both sides of the shell 5 for use with the first connecting rod 27 and the second connecting rod 205, and one end of the first connecting rod 27 and both ends of the second connecting rod 205 are respectively slidably connected to the inner walls of one side of the corresponding positioning groove 207.

The movement of the second toothed plate 206 drives the second connecting rod 205 to move toward the direction of the first connecting rod 27. The positioning groove 207 serves to guide the first connecting rod 27 and the second connecting rod 205 when they move. The first connecting rod 27 and the second connecting rod 205 move simultaneously through the long block 204 to drive the two positioning plates 26 to move toward the opposite surface to position the muffler. At the same time, the through groove 25 serves to limit the moving position of the long block 204.

[0028] Then, the second cylinder 33 is started through the flipping mechanism 3, and the output end of the second cylinder 33 drives the first vertical rod 32 to move back and forth. The second guide sleeve 35 serves to guide the movement of the first vertical rod 32. The first vertical rod 32 moves back and forth to drive the movable frame 36 to move up and down. The first guide sleeve 303 cooperates with the second vertical rod 31 to guide the movable frame 36 when it moves. The movable frame 36 moves up and down and cooperates with the lever 37 to rotate the disc 38. The rotation of the disc 38 drives the connecting piece 301 to rotate through the round rod 39. At the same time, the slot 302 facilitates the positioning of the connecting piece 301. The rotation of the connecting piece 301 drives the shell 5 to rotate, so that the positioned muffler is flipped, and then the muffler can be welded by welding tools.
