Detailed Embodiment

[0021] It should be noted that the terms "first", "second", etc. in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. For the embodiments of this application described here, based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0022] Refer to Figures 1 - 3, A bellows welding mechanism facilitating loading, comprising a bottom plate 1. The upper surface of the bottom plate 1 is fixedly bolted with a bracket 2. A welding assembly is installed at the top of the bracket 2. Through grooves 8 are opened on both sides of the bracket 2. Arc-shaped grooves 5 communicating with the through grooves 8 are opened around the through grooves 8. A turntable 9 is rotatably connected in the adjacent through groove 8 and arc-shaped groove 5. A threaded rod 6 is threadedly connected inside the turntable 9. One end of the threaded rod 6 passes through the turntable 9 and is installed with a clamping plate 11. The welding surfaces of two bellows to be welded are butted and contacted. Then the threaded rod 6 is rotated to move the clamping plate 11 to clamp and fix the two bellows, thus facilitating the staff to load the bellows. Then the welding assembly moves downward to weld the two clamped bellows. Multiple connecting blocks 18 are fixedly bolted on one side of the turntable 9. Sockets 17 are opened inside the connecting blocks 18. A fixing block 13 is fixedly bolted on the outer wall of one side of the bracket 2. A guide rod 14 is inserted and slid in the fixing block 13. A pin 16 is fixedly bolted at one end of the guide rod 14. The guide rod 14 can guide the pin 16 to move stably, and the pin 16 is inserted in the socket 17. When it is necessary to change the welding position, the guide rod 14 is pulled outward to make the pin 16 move out of the socket 17, and the spring 15 contracts. At this time, the turntable 9 is no longer restricted. The threaded rod 6 is rotated to drive the turntable 9 and its connected components to rotate as a whole, so that the clamped bellows rotate to the position where welding is required. The pull ring 12 is released, and the spring 15 rebounds to make the pin 16 re-insert into the socket 17, thus facilitating the welder 3 to perform circular welding on different positions of the bellows.

[0023] In the present utility model, it should be noted that a spring 15 is sleeved outside the guide rod 14, and both ends of the spring 15 are fixed to the pin 16 and the fixing block 13 respectively. The spring 15 facilitates the automatic reset of the pin 16. The welding assembly includes a hydraulic cylinder 4. The hydraulic cylinder 4 is fixedly bolted on the outer wall of the top of the bracket 2. One end of the hydraulic rod of the hydraulic cylinder 4 passes through the bracket 2 and is installed with a welder 3. The hydraulic cylinder 4 extends to move the welder 3 downward to weld the two bellows. The welder 3 is located above the two clamping plates 11. One end of the guide rod 14 extends out of the fixing block 13 and is welded with a pull ring 12 to facilitate the staff to pull the guide rod 14. One end of the threaded rod 6 is welded with a knob 7 to facilitate the staff to rotate the threaded rod 6 labor-saving. A rubber pad 10 is adhered to one side of the clamping plate 11. The rubber pad 10 can protect the bellows to avoid abrasion caused by the bellows directly contacting the clamping plate 11 for a long time.

[0024] Working principle: When welding the diaphragm box, first dock the welding surfaces of the two half diaphragm boxes to be welded, then rotate the threaded rod 6 to move the clamping plate 11 to clamp and fix the two diaphragm boxes. Then start the hydraulic cylinder 4 and the welder 3. The hydraulic cylinder 4 extends to move the welder 3 downward to weld the two diaphragm boxes. When it is necessary to change the welding position, pull the pull ring 12 outward to make the guide rod 14 move along the fixed block 13, so that the plug pin 16 moves out of the socket 17 and the spring 15 contracts. At this time, the turntable 9 is no longer restricted. Rotate the threaded rod 6 to drive the turntable 9 and its connected components to rotate as a whole, so that the clamped diaphragm box rotates to the position to be welded. Release the pull ring 12, and the spring 15 rebounds to make the plug pin 16 re-insert into the socket 17, which is convenient for the welder 3 to perform circumferential welding at different positions of the diaphragm box.
