[0030] The limiting mechanism 3 includes a transmission unit and a limiting unit;

[0031] The transmission unit is used to provide thrust for the movement of the limit unit;

[0032] The limiting unit is used to clamp and limit the welding material 2;

[0033] The limiting unit includes a clamping block 301 and a limiting block 302;

[0034] The clamping block 301 is vertically slidably mounted on the inner wall of the rotating base 1 and extends to the outside of the rotating base 1. The clamping block 301 is used to provide support for the inner side of the solder 2.

[0035] The limit block 302 is slidably mounted on the top of the clamping block 301, and the limit block 302 is used to cooperate with the clamping block 301 to further improve the clamping force on the solder 2;

[0036] The transmission unit includes a guide rod 303, a stop block 304, a rotating ring 305, a gear ring 306, and an elastic rod 307;

[0037] The guide rod 303 is slidably mounted on the top of the clamping block 301, and the guide rod 303 is used to drive the stop block 304 to move synchronously;

[0038] The stopper 304 is fixed to an outer wall of one side of the guide rod 303, and the stopper 304 is used to give thrust to the limit block 302 during the movement;

[0039] The rotating ring 305 is rotatably mounted on an outer wall of one side of the rotating seat 1, and the rotating ring 305 is used to drive the guide rod 303 to move synchronously;

[0040] The gear ring 306 is fixed to the outer wall of the rotating ring 305, and the gear ring 306 is used to receive the thrust from the elastic rod 307;

[0041] The elastic rod 307 is installed on a support frame at one side of the rotating seat 1 , and the elastic rod 307 is used to give a thrust to the gear ring 306 during the rotation of the rotating ring 305 .

[0042] In this embodiment: when using this device, by placing the material to be welded 2 on one side of the rotating seat 1, the inner side of the material to be welded 2 surrounds the outer side of the clamping block 301, and the three clamping blocks 301 are pushed by using a cylinder to move and contact the inner side of the material to be welded 2. At this time, the protrusions at the top of the clamping blocks 301 will be on the side of the wall thickness of the clamping blocks 301. At this time, the rotating seat 1 can be driven to rotate as a whole by using a reduction motor connected to the end of the rotating seat 1. The rotating rotating seat 1 will synchronously drive the clamping block 301, the rotating ring 305, and the material to be welded 2 to rotate. The rotating rotating ring 305 will synchronously drive the toothed ring 306 fixed on the outer wall to rotate. The rotating toothed ring 306 and the stationary elastic The ends of the rods 307 are in contact, and the gear ring 306 is forced to transfer the rotational force to the rotating ring 305. The rotating ring 305 is forced to rotate and synchronously drives the guide rod 303 with the inner sliding sleeve to move. The moving guide rod 303 synchronously drives the stop block 304 to move.

The moving limit block 302 will gradually move toward the outer wall of the wall thickness of the material 2 to be welded until it contacts, so that the material 2 to be welded is subjected to the outward expansion force from the clamping block 301 during the welding process, and is also subjected to the clamping force from the limit block 302, thereby further improving the clamping stability of the material 2 to be welded.

[0043] Please refer to Figure 1-Figure 3 The rotation trajectory of the gear ring 306 coincides with the position of the end of the elastic rod 307. The outer wall of the elastic rod 307 is in an arc shape as a whole. The inner cavity of the rotating ring 305 is formed with a sliding groove for the vertical movement of the guide rod 303. The outer wall of the side of the stop block 304 close to the limit block 302 is inclined. The top of the clamping block 301 is formed with a sliding groove for the lateral movement of the limit block 302 and an arc groove for the movement of the guide rod 303. There are three guide rods 303, and the three guide rods 303 are evenly distributed at the top of the clamping block 301.

[0044] In this embodiment: through this structure, when the rotating ring 305 rotates as a whole with the rotating seat 1, the toothed ring 306 will contact the end of the elastic rod 307, thereby driving the rotating ring 305 to rotate so that the stop block 304 is pressed against the outer wall of the limit block 302 until the outer wall of the limit block 302 contacts the wall thickness of the material to be welded 2, and at this time the guide rod 303, the stop block 304 and the rotating ring 305 no longer rotate, the toothed ring 306 will give a thrust to the elastic rod 307 to deform the elastic rod 307, and the elastic rod 307 which is in contact with the toothed ring 306 will continuously give a thrust to the toothed ring 306 to clamp the wall thickness of the material to be welded 2.
