More specifically, when the circular water tank needs to be fixed, first place the circular water tank on the follower base 2, press the start button, and push the driving wheel mechanism 6 to move horizontally through the clamping mechanism 5, so that the driving wheel mechanism 6 moves closer to the idler mechanism 3, so that the surface of the driving wheel mechanism 6 contacts the circular water tank, thereby clamping the circular water tank, and then the end face of the circular water tank is pressed by the spinning and pressing mechanism 7, and the roller part of the driving wheel mechanism 6 is driven to rotate by the driving mechanism 8. The roller part rotates the circular water tank under the action of friction, and the circular water tank is welded by the laser welding gun at the same time. After welding is completed, the driving mechanism 8 stops driving the roller part of the driving wheel mechanism 6 to rotate, and the driving wheel mechanism 6 is driven by the clamping mechanism 5 to move backward to release the circular water tank, so that the circular water tank can be taken out.

[0025] The idler mechanism 3 includes a first side plate 301, which is fixedly mounted on the top surface of the base plate 1. Two sets of first protrusions 302 are fixedly mounted on the end surfaces of the first side plate 301. A first rotating shaft 303 is rotatably mounted within the first protrusions 302 via bearings. A first clamping wheel 304 is fixedly sleeved on the surface of the first rotating shaft 303. More specifically, after the circular water tank is attached to the follower base 2, the surface of the circular water tank is brought into contact with the surface of the first clamping wheel 304. The roller portion of the driving wheel mechanism 6 is brought into contact with the surface of the circular water tank. The driving wheel mechanism 6 is driven by the driving mechanism 8 to rotate the circular water tank, causing the first clamping wheel 304 and the first rotating shaft 303 to rotate.

[0026] The active mechanism base 4 includes a second side frame 401, which is fixedly mounted on the top surface of the base plate 1. L-shaped reinforcement plates 402 are fixedly mounted on the top surface of the base plate 1 and the end surface of the second side frame 401.

A mounting block 703 is fixedly mounted on the output end of the hydraulic rod 702, and a pressure roller 704 is rotatably mounted on the surface of the mounting block 703. More specifically, with the support base 701 positioned at the front and rear sides of the circular water tank, the hydraulic rod 702 drives the mounting block 703 and the pressure roller 704 to move vertically, causing the pressure roller 704 to contact the end surface of the circular water tank. When the pressure roller 704 contacts the top of the circular water tank, the circular water tank is vertically limited.

[0029] The driving mechanism 8 includes a motor mounting plate 801, a motor mounting plate 801 being fixedly mounted on one end surface of the movable plate 602, and a motor 802 being fixedly mounted on the top surface of the motor mounting plate 801.

More specifically, the motor 802 drives the small pulley 803 to rotate, and the rotation of the small pulley 803 causes the belt 805 to drive the two sets of large pulleys 804 and the second rotating shaft 604 to rotate synchronously.

[0030] In summary: when the circular water tank needs to be fixed, first place the circular water tank on the follower base 2, press the start button, and push the driving wheel mechanism 6 to move horizontally through the clamping mechanism 5, so that the driving wheel mechanism 6 moves closer to the idler mechanism 3, so that the surface of the driving wheel mechanism 6 contacts the circular water tank, thereby clamping the circular water tank, and then the end face of the circular water tank is pressed by the spinning and pressing mechanism 7, and the roller part of the driving wheel mechanism 6 is driven to rotate by the driving mechanism 8. The roller part rotates the circular water tank under the action of friction, and the circular water tank is started to be welded by the laser welding gun at the same time. After welding is completed, the driving mechanism 8 stops driving the roller part of the driving wheel mechanism 6 to rotate, and the driving wheel mechanism 6 is driven by the clamping mechanism 5 to move backward to release the circular water tank, so that the circular water tank can be taken out.
