A rectangular through groove is opened inside the mounting shaft 4.

[0018] A first drive motor 7 is installed at the center position of the turntable 5 corresponding to the inside of the workbench 1. The output end of the first drive motor 7 is connected to the rotating shaft 2. The upper end of the rotating shaft 2 is fixedly connected with a positioning plate 3 that is adapted to the through groove inside the mounting shaft 4. The mounting shaft 4 is mounted on the positioning plate 3. The first drive motor 7 serves as a first drive unit to drive the rotating shaft 2 to rotate.

[0019] A baffle plate 6 is fixedly connected to the lower portion of the positioning plate 3 , and the baffle plate 6 is used to limit the position of the mounting shaft 4 .

[0020] A fixing groove 8 is opened on the upper part of the positioning plate 3, and a first screw rod 9 is arranged inside the fixing groove 8 along the width direction of the positioning plate 3, and the two ends of the first screw rod 9 are respectively rotatably connected with the positioning plate 3; the first screw rod 9 is a left and right bidirectional screw, and L-shaped fixing plates 10 are respectively threadedly connected on the threads at both ends of the first screw rod 9; the positioning plate 3 is respectively provided with slots corresponding to the horizontal sections of the fixing plate 10, and the horizontal sections of the fixing plate 10 can slide along the slots.

[0021] The inner wall of the installation shaft 4 is provided with a matching slot 11 corresponding to the horizontal section of each fixing plate 10 , and the upper end of the positioning plate 3 is connected to the installation shaft 4 through the fixing plate 10 .

[0022] In this embodiment, in order to facilitate the rotation of the first screw rod 9, hexagonal adjustment grooves 12 are respectively opened on the end surfaces at both ends of the first screw rod 9, and the first screw rod 9 is rotated by a hexagonal wrench.

[0023] When disassembling the turntable 5, rotate the first screw rod 9 to make the two fixing plates 10 move 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 on the positioning plate 3. When the lower end of the mounting shaft 4 contacts the baffle 6, use a hexagonal wrench to rotate the first screw rod 9 to make the two fixing plates 10 move in the opposite direction 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, thereby improving the replacement efficiency.

[0024] The turntable 5 is evenly provided with a plurality of through holes around its central axis, and a positioning mold 13 is rotatably connected in each through hole. The positioning mold 13 is composed of a positioning head 1301 and an intermediate rod 1302. The positioning head 1301 is fixedly connected to the upper end of the intermediate rod 1302. The centers of the positioning head 1301 and the intermediate rod 1302 are provided with continuous limiting holes 1303. The top of the positioning head 1301 is provided with a plurality of fixing blocks 14 spaced along the outer edge thereof. The fixing blocks 14 are used to position the water stop plate.

[0025] A gear ring 15 is mounted on the lower end of the middle rod 1302; a second drive motor 16 is arranged inside the workbench 1, and a connecting plate 17 is installed above the second drive motor 16 inside the workbench 1, and a connecting shaft 18 is rotatably connected to the connecting plate 17, and the lower end of the connecting shaft 18 is connected to the output end of the second drive motor 16, and a gear 19 is installed on the upper end of the connecting shaft 18, and the gear 19 is placed above the connecting plate 17, and the gear 19 is meshed with the gear ring 15. The second drive motor 16 drives the connecting shaft 18 to rotate as a second drive unit, and the rotation of the connecting shaft 18 drives the gear 19 to rotate, and the gear 19 meshes with the gear ring 15 to rotate the middle rod 1302, thereby realizing that the second drive motor 16 drives the bolts and water stop plates on the positioning mold 13 to rotate accordingly.

[0026] like Figures 5 to 8 As shown, the welding mechanism consists of a mounting seat 20, a guide rail 21 and a mounting plate 22. The mounting seat 20 is fixed on the workbench 1. A slide groove adapted to the guide rail 21 is provided on the mounting seat 20. When the guide rail 21 cooperates with the mounting seat 20, the guide rail 21 passes through the slide groove and is slidably connected to the mounting seat 20 through the slide groove; the mounting plate 22 is fixedly installed above the mounting seat 20, and a mounting hole 23 is provided on the upper part of the mounting plate 22, and the welding gun is installed in the mounting hole 23.

[0027] In this embodiment, an adjustment hole 24 connected to the mounting hole 23 is provided on one side of the mounting plate 22. The adjustment hole 24 is a threaded hole. The central axis of the adjustment hole 24 is perpendicular to the central axis of the mounting hole 23. The internal thread of the adjustment hole 24 is connected to a second screw rod 25. The end of the second screw rod away from the mounting plate 22 is fixedly connected to a handle 26. The position of the welding gun can be adjusted along the axial direction of the mounting hole 23 by turning the handle 26 to screw out the second screw rod 25. After the position of the welding gun is adjusted, the handle 26 is turned to screw in the second screw rod 25 so that the second screw rod 25 is pressed against the welding gun.

[0028] The bottom of the guide rail 21 is provided with a plurality of fixed slots 27 at equal intervals along its length direction. A limiting slot 28 is provided inside the slide slot at a position corresponding to the fixed slot 27. A limiting block 29 is slidably connected inside the limiting slot 28, and the limiting block 29 is plugged into the limiting slot 28.

[0029] In this embodiment, a pressing groove 31 is further provided on one side of the mounting seat 20 corresponding to the limiting groove 28, and the lower end of the pressing groove 31 is connected to the limiting groove 28 and the two form an L-shaped groove; a slide plate 30 is provided in the limiting groove 28, and the slide plate 30 slides up and down along the limiting groove 28; one end of the slide plate 30 extends to the bottom of the fixed slot 27, and the limiting block 29 is fixed to the extended end of the slide plate 30, and 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 slide plate 30; the bottom of the slide plate 30 is connected to the inner wall of the limiting slot 28 through a spring 33. When adjusting the horizontal position of the welding gun, the pressing block 32 is pressed downward. When the pressing block 32 moves downward, it drives the slide plate 30 to move downward. When the slide plate 30 moves downward, the spring 33 contracts. At the same time, the slide plate 30 drives the limit 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 gun; after the welding gun position is adjusted to the specified position, the pressing block 32 is released. The slide plate 30 moves upward under the action of the elastic force of the spring 33, and the limit block 29 is engaged with the limit slot 11 to fix the guide rail 21 and the mounting seat 20, thereby improving the stability of the welding gun.

[0030] When the device is used, the water stop plate is first placed on each positioning mold 13 for positioning, and then the bolt is inserted through the water stop plate into the positioning mold 13, and then the first drive motor 7 is started. The output shaft of the first drive motor 7 rotates to drive the rotating shaft 2 to rotate, and the rotating shaft 2 rotates to drive the positioning plate 3 to rotate, and the positioning plate 3 rotates to drive the mounting shaft 4 to rotate, and the mounting shaft 4 drives the turntable 5 to rotate, and the turntable 5 drives the multiple positioning molds 13 thereon to rotate to the mounting plate 22 in sequence; since a welding gun is installed on the mounting plate 22, the water stop plate and the bolt can be welded by the welding gun; at the same time, the second drive motor 16 is started, and the output end of the second drive motor 16 rotates to drive the gear 19 to rotate, and the gear 19 rotates the intermediate rod 1302 through the meshing transmission with the gear ring 15, and the intermediate rod 1302 drives the positioning head 1301 to rotate, and then drives the water stop plate and the bolt to rotate, so as to cooperate with the welding gun to weld the joint between the water stop plate and the bolt. When it is necessary to adjust the horizontal position of the welding gun according to bolts of different diameters, the pressing block 32 is pressed down. When the pressing block 32 moves downward, it drives the slide plate 30 to move downward. When the slide plate 30 moves downward, the spring 33 contracts, and at the same time, the slide plate 30 drives the limit 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 gun; after the welding gun position is adjusted to the specified position, the pressing block 32 is released, and the slide plate 30 moves upward under the action of the elastic force of the spring 33, and the limit block engages with the limit slot 11 to fix the guide rail 21 and the mounting seat 20.

[0031] When it is necessary to replace a different positioning mold 13, the first screw rod 9 is rotated by plugging the hexagonal wrench into the adjusting slot 12, and the two fixing plates 10 on the first screw rod 9 move in the opposite direction until the ends of the two fixing plates 10 move into the slots respectively, and the fixing plates 10 release the limit on the mounting shaft 4, and the turntable 5 and the mounting shaft 4 are removed; then the mounting shaft 4 of the replaced turntable 5 is sleeved on the positioning plate 3, and when the lower end of the mounting shaft 4 contacts the baffle 6, the first screw rod 9 is rotated with a hexagonal wrench to make the two fixing plates 10 move in the opposite direction until the horizontal section of the fixing plate 10 is inserted into the slot 11, and at this time, the fixing plate 10 connects and fixes the positioning plate 3 and the mounting shaft 4, and this operation can replace the positioning molds 13 on the same turntable 5 at the same time without disassembling them one by one, thereby improving the replacement efficiency.

[0032] The present invention adds a positioning plate on the top of the rotating shaft and arranges a detachable mounting shaft outside the positioning plate, so that the turntable and the positioning mold thereon can be quickly replaced, and multiple positioning molds can be disassembled at the same time without the need to disassemble and replace each positioning mold one by one, thereby greatly improving the mold replacement efficiency and shortening the welding cycle.
