[0033] A limit plate 66 is fixedly connected to the surface of the limit rod 65, and a pull plate 67 is fixedly connected to the end of the limit rod 65 away from the connecting block 61.

The provision of the pull plate 67 facilitates the installation of the spring 68 and facilitates the restriction of the position of the limit rod 65.

[0034] Reference Figure 1 and Figure 2 as well as Figure 4 and Figure 5 As shown, specifically, the control device 7 includes two movable plates 71, and the two movable plates 71 are fixedly connected to one end of the pressure rod 54 away from the fixed inner cylinder 53, and the inner wall threads of the two movable plates 71 are threaded with a bidirectional screw 76. By providing the movable plates 71, the bidirectional screw 76 and the pressure rod 54 can be connected. By providing the bidirectional screw 76, the movement of the two movable plates 71 can be conveniently controlled synchronously. The sides of the two movable plates 71 that are close to each other are fixedly connected to a slide plate 72, the surface of the slide plate 72 is covered with a sleeve plate 73, and both ends of the bidirectional screw 76 are fixedly connected to a rotating plate 77. The slide plate 72 slidably connected to the inner wall of the sleeve plate 73 can move. By providing the slide plate 72 and the sleeve plate 73, the stability of the movable plate 71 during movement can be improved.

[0035] A fixing block 74 is fixedly connected to the surface of the rotating outer cylinder 52. The fixing block 74 is fixedly connected to the sleeve plate 73. A mounting plate 75 is fixedly connected to the surface of the rotating outer cylinder 52. The mounting plate 75 is rotatably connected to the surface of the bidirectional screw 76. The provision of the fixing block 74 secures the sleeve plate 73 to the rotating outer cylinder 52. The provision of the mounting plate 75 ensures a stable connection between the bidirectional screw 76 and the rotating outer cylinder 52, while also ensuring that the bidirectional screw 76 can rotate.

[0036] Working principle: when using the bellows welding device to weld the bellows, first use the supporting mechanism 4 and the fixing mechanism 5 on the base plate 1 to install the connecting piece and the bellows. First, move the bellows so that it is stuck between the rotating outer cylinder 52 and the fixed inner cylinder 53 on the second rectangular plate 51, fix the bellows through the pressure rod 54, move the connecting piece close to the supporting block 43, install the connecting piece, adjust the position of the supporting block 43 through the electric telescopic rod 42 on the first rectangular plate 41, and then use the welder 3 on the "L"-shaped plate 2 to weld the two. When the support block 43 needs to be replaced, the pull plate 67 is pulled to drive the limit rod 65 to slide on the inner wall of the curved plate 64, so that the limit rod 65 and the limit plate 66 move away from the connecting block 61, releasing the restriction on the position of the support block 43, moving the support block 43 away from the electric telescopic rod 42, moving the support block 43 to be replaced close to the electric telescopic rod 42, pulling the pull plate 67 away from the curved plate 64, moving the abutment plate 62 to fit with the connecting block 61, and completing the positioning work through the positioning plate 63, releasing the pull plate 67, and when the spring 68 rebounds, Under the action of force, the limit rod 65 is stuck in the connecting block 61, completing the replacement of the supporting block 43. By setting up the replacement device 6, the supporting block 43 used to support the connecting piece can be conveniently replaced during the process of using the bellows welding device to weld bellows of different sizes. Therefore, the bellows welding device can be suitable for welding bellows of different sizes, thereby improving the flexibility of the use of the bellows welding device and improving the adaptability of the supporting block 43 to the connecting piece, providing a better supporting effect for the connecting piece.

[0037] After the bellows is stuck in the rotating outer cylinder 52, the rotating plate 77 drives the bidirectional screw 76 to rotate on the inner wall of the mounting plate 75. At this time, driven by the bidirectional screw 76, the two movable plates 71 drive the pressure rod 54 to move closer to each other. At the same time, the movable plate 71 drives the slide plate 72 to slide on the inner wall of the sleeve plate 73, so that the two pressure rods 54 adjust the position of the bellows while fixing the bellows. By setting the fixing block 74, the sleeve plate 73 can be connected to the rotating outer cylinder 52. By setting the control device 7, the pressure rod 54 can be controlled to move synchronously during the process of fixing the bellows to the rotating outer cylinder 52 on the bellows welding device, so that the position of the bellows can be positioned while the bellows is fixed, which is convenient for subsequent welding of the bellows.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
