[0029] The upper part of the positioning plate 3 is provided with a fixing groove 8. A first lead screw 9 is provided inside the fixing groove 8 along the width direction of the positioning plate 3. The two ends of the first lead screw 9 are rotatably connected to the positioning plate 3. The first lead screw 9 is a left and right bidirectional lead screw. L-shaped fixing plates 10 are threadedly connected to the threads at both ends of the first lead screw 9. The positioning plate 3 is provided with slots corresponding to the horizontal sections of the fixing plates 10. The horizontal sections of the fixing plates 10 can slide along the slots.

[0030] The inner wall of the mounting shaft 4 is provided with a corresponding slot 11 for each horizontal section of the fixing plate 10. The upper end of the positioning plate 3 is engaged with the mounting shaft 4 through the fixing plate 10.

[0031] In this embodiment, in order to facilitate the rotation of the first lead screw 9, an internal hexagonal adjustment groove 12 is provided on the end face of both ends of the first lead screw 9, and the first lead screw 9 is rotated by a hexagonal wrench.

[0032] When disassembling the turntable 5, rotate the first screw 9 to move the two fixing plates 10 toward each other, so that the end of the horizontal section of the fixing plate 10 moves into the slot, and remove the turntable 5 and the mounting shaft 4; then, put the mounting shaft 4 of the replaced turntable 5 onto the positioning plate 3. When the lower end of the mounting shaft 4 contacts the baffle 6, use a hex wrench to rotate the first screw 9 to move the two fixing plates 10 in opposite directions until the horizontal section of the fixing plate 10 is inserted into the slot 11. At this time, the fixing plate 10 connects and fixes the positioning plate 3 and the mounting shaft 4. This operation can replace the positioning mold 13 on the same turntable 5 at the same time without disassembling them one by one, which improves the replacement efficiency.

[0033] The turntable 5 has several through holes evenly distributed around its central axis, and a positioning mold 13 is rotatably connected to each through hole. The positioning mold 13 consists of a positioning head 1301 and an intermediate rod 1302. The upper end of the positioning head 1301 and the intermediate rod 1302 are fixedly connected.

The gear 19 is positioned above the connecting plate 17 and meshes with the gear ring 15. The second drive motor 16, as the second drive unit, drives the connecting shaft 18 to rotate. The rotation of the connecting shaft 18 drives the gear 19 to rotate. The gear 19 meshes with the gear ring 15, causing the intermediate rod 1302 to rotate. Thus, the second drive motor 16 drives the bolts and waterstops on the positioning mold 13 to rotate accordingly.

[0035] like Figures 5 to 8 As shown, the welding mechanism consists of a mounting base 20, a guide rail 21, and a mounting plate 22. The mounting base 20 is fixed on the workbench 1. The mounting base 20 has a groove that matches the guide rail 21. When the guide rail 21 and the mounting base 20 are engaged, the guide rail 21 passes through the groove and is slidably connected to the mounting base 20 through the groove. The mounting plate 22 is fixedly installed above the mounting base 20, and the upper part of the mounting plate 22 has a mounting hole 23. The welding torch is installed in the mounting hole 23.

[0036] In this embodiment, an adjustment hole 24 communicating with the mounting hole 23 is provided on one side of the mounting plate 22. The adjustment hole 24 is a threaded hole, and the central axis of the adjustment hole 24 is perpendicular to the central axis of the mounting hole 23. A second lead screw 25 is threaded into the adjustment hole 24, and a handle 26 is fixedly connected to the end of the second lead screw away from the mounting plate 22. By rotating the handle 26 to screw out the second lead screw 25, the position of the welding gun can be adjusted along the axial direction of the mounting hole 23. After the position of the welding gun is adjusted, the handle 26 is rotated to screw in the second lead screw 25, so that the second lead screw 25 is pressed against the welding gun.

[0037] The bottom of the guide rail 21 is provided with several fixed slots 27 at equal intervals along its length. The inside of the slide groove is provided with a limit groove 28 corresponding to the position of the fixed slot 27. The limit groove 28 is slidably connected to the limit block 29, and the limit block 29 and the limit groove 28 are engaged and inserted.

[0038] In this embodiment, the mounting base 20 is also provided with a pressing groove 31 on one side corresponding to the limiting groove 28. The lower end of the pressing groove 31 is connected to the limiting groove 28 and the two form an L-shaped groove. A sliding plate 30 is provided in the limiting groove 28 and slides up and down along the limiting groove 28. One end of the sliding plate 30 extends to the bottom of the fixing slot 27, and the limiting block 29 is fixed to the extended end of the sliding plate 30. A pressing block 32 is slidably connected inside the pressing groove 31, and the lower end of the pressing block 32 is connected and fixed to the other end of the sliding plate 30. The bottom of the sliding plate 30 is connected to the inner wall of the limiting groove 28 through a spring 33. When adjusting the horizontal position of the welding torch, press down on the pressing block 32. When the pressing block 32 moves downward, it drives the sliding plate 30 to move downward. When the sliding plate 30 moves downward, the spring 33 contracts. At the same time, the sliding plate 30 drives the limiting block to disengage from the fixed slot 27. At this time, the guide rail 21 can be pushed to adjust the position of the welding torch. After the welding torch position is adjusted to the specified position, release the pressing block 32. The sliding plate 30 moves upward under the action of the spring 33. The limiting block 29 engages with the limiting slot 11, fixing the guide rail 21 and the mounting base 20, thereby improving the stability of the welding torch.

[0039] In application, the waterstop plate is first placed on each positioning mold 13 for positioning. Then, the bolt is inserted through the waterstop plate into the positioning mold 13. The first drive motor 7 is then started. The output shaft of the first drive motor 7 rotates, driving the rotating shaft 2 to rotate. When the rotating shaft 2 rotates, it drives the positioning plate 3 to rotate. When the positioning plate 3 rotates, it drives the mounting shaft 4 to rotate. The mounting shaft 4 drives the turntable 5 to rotate. The turntable 5 drives the multiple positioning molds 13 on it to rotate sequentially to the mounting plate 22. Since a welding gun is installed on the mounting plate 22, the waterstop plate and the bolt can be welded by the welding gun. At the same time, the second drive motor 16 is started. When the output end of the second drive motor 16 rotates, it drives the gear 19 to rotate. The gear 19 rotates through meshing with the gear ring 15, causing the intermediate rod 1302 to rotate. The intermediate rod 1302 drives the positioning head 1301 to rotate, which in turn drives the waterstop plate and the bolt to rotate, so as to cooperate with the welding gun to weld the joint between the waterstop plate and the bolt. When the horizontal position of the welding torch needs to be adjusted according to bolts of different diameters, press down the pressing block 32. When the pressing block 32 moves downward, it drives the sliding plate 30 to move downward. When the sliding plate 30 moves downward, the spring 33 contracts. At the same time, the sliding plate 30 drives the limiting block to disengage from the fixing slot 27. At this time, the guide rail 21 can be pushed to adjust the position of the welding torch. After the position of the welding torch is adjusted to the specified position, release the pressing block 32. The sliding plate 30 moves upward under the action of the spring 33. The limiting block engages with the limiting slot 11, fixing the guide rail 21 and the mounting base 20.

[0040] When it is necessary to replace different positioning molds 13, the first lead screw 9 is rotated by connecting a hex wrench to the adjusting groove 12. The two fixing plates 10 on the first lead screw 9 move in opposite directions until the ends of the two fixing plates 10 move into the slots respectively. The fixing plates 10 release the restriction on the mounting shaft 4, and the turntable 5 and mounting shaft 4 are removed. Then, the mounting shaft 4 of the replaced turntable 5 is fitted onto the positioning plate 3. When the lower end of the mounting shaft 4 contacts the baffle 6, the first lead screw 9 is rotated with a hex wrench, causing the two fixing plates 10 to move in opposite directions until the horizontal section of the fixing plate 10 is inserted into the slot 11. At this time, the fixing plate 10 connects and fixes the positioning plate 3 and the mounting shaft 4. This operation can replace the positioning molds 13 on the same turntable 5 at the same time without disassembling them one by one, which improves the replacement efficiency.

[0041] This invention adds a positioning plate to the top of the rotating shaft and sets a detachable mounting shaft on the outside of the positioning plate, which enables the turntable and the positioning molds on it to be quickly replaced. Multiple positioning molds can be disassembled at the same time without having to disassemble and replace each positioning mold one by one, which greatly improves the mold replacement efficiency and shortens the welding cycle.

[0042] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
