Its lifting movement ensures the flexibility of the cooling water pipe 312 in the overturning process, while ensuring the cooling effect of the welding surface, one end of the rotating shaft A31 away from the inner wall of the welding box 1 is fixedly connected with a mounting plate 39, the outer wall of the mounting plate 39 is fixedly connected with an electric telescopic rod A310, the output end of the electric telescopic rod A310 is fixedly connected with a clamping plate 311, the inner side of the clamping plate 311 is provided with an antiskid rubber pad, which enhances the adaptability to different shaped workpieces, the inside bottom end of the welding box 1 is fixedly connected with a water tank 313, the inside of the water tank 313 is provided with a water pump, the output end of the water pump is fixedly connected with a conveying pipe 314, the other end of the conveying pipe 314 is fixedly connected with the water storage frame 37, the water tank 313 provides a cooling water source, and the water pump is responsible for pumping water from the water tank 313 and conveying it to the water storage frame 37 and the cooling water pipe 312 through the conveying pipe 314. The working of the water pump ensures the flow of cooling water in the system and effectively cools the welding surface, the outer wall of the rotating shaft A31 is assembled with a cooling assembly 5, and the upper end of the welding box 1 is assembled with a moving assembly 4. The inner wall bottom end of the welding box 1 is fixedly connected with a limiting rod 315, the outer wall of the water storage frame 37 is fixedly connected with a connecting plate 316, the connecting plate 316 is slidingly connected to the outer wall of the limiting rod 315, the surface of the limiting rod 315 is chrome plated to reduce friction, and the connecting plate 316 is made of lightweight aluminum alloy material. The outer wall of the welding box 1 is fixedly connected with a motor 38, the output end of the motor 38 is fixedly connected with one side of the rotating shaft A31, a servo motor 38 is used to accurately control the rotating angle of the rotating shaft, and the stability of the overturning action is ensured.

[0036] When in use, first, the welded case accessory is placed between the two clamping plates 311, then the electric telescopic rod A310 is started to drive the clamping plates 311 to move to the middle, and then when the two clamping plates 311 contact the case accessory, the welding work of the case accessory can be carried out through the welding gun 2, when the welding is completed, the motor 38 is started to drive the rotating shaft A31 on one side to rotate, and then the mounting plate 39 at the other end of the rotating shaft A31 is rotated, and then the case accessory fixed by the electric telescopic rod A310 and the clamping plate 311 on the outer wall of the mounting plate 39 can be turned over, when the rotating shaft A31 rotates, the transmission gear A32 on the outer wall of the rotating shaft A31 rotates, then the transmission gear B33 engaged with the transmission gear A32 rotates, thereby driving the rotating shaft B34 to rotate, then the connecting rod A35 at the other end of the rotating shaft B34 rotates around the rotating shaft B34, then the connecting rod B36 rotationally connected with the connecting rod A35 drives the water storage frame 37 to move downward, and the connecting plate 316 on the side of the water storage frame 37 slides on the outer wall of the limiting rod 315, thereby ensuring the stability of the movement of the water storage frame 37, since the gear ratio between the transmission gear A32 and the transmission gear B33 is designed, when the transmission gear A32 rotates 180 degrees, the transmission gear B33 just rotates 360 degrees, that is, after the case accessory is turned over, the water storage frame 37 and the cooling water pipe 312 inside it just return to the initial position, at this time, the water storage frame 37 and the cooling water pipe 312 are located at the lower end of the welded surface of the case accessory, thereby the cooling can be realized, and the water pump can be started to flow the water in the water tank 313 with the cooling water pipe 312 and the water storage frame 37, thereby ensuring the cooling effect, the above design ensures that the water storage frame 37 and the cooling water pipe 312 are lowered to provide a space for the movement of the water storage frame 37 and the cooling water pipe 312 when the case accessory is turned over, and after the turning over is completed, the water storage frame 37 and the cooling water pipe 312 are reset to cool the welding surface, and the other surface of the case accessory can also be welded, thereby improving the work efficiency.

[0037] Embodiment two, please refer to Figures 1-6The moving assembly 4 comprises an L-shaped plate 41 fixedly connected to the top of the welding box 1, a sliding groove 42 is formed in the top of the L-shaped plate 41, a moving block 43 is slidably connected inside the sliding groove 42, the welding gun 2 is fixedly connected to the bottom of the moving block 43 through the electric telescopic rod B, the top of the L-shaped plate 41 and the outer wall of the welding box 1 are fixedly connected with a mounting seat A 44 and a mounting seat B 45, the mounting seat A 44 and the mounting seat B 45 are rotatably connected with a guide wheel A 46 and a guide wheel B 47 respectively, the outer wall of the moving block 43 is fixedly connected with a connecting rope 48, the other end of the connecting rope 48 is fixedly connected with a side connecting plate 316, a spring 410 is fixedly connected to the inner wall of the sliding groove 42, the other end of the spring 410 is fixedly connected with the moving block 43, the stiffness of the spring 410 matches the weight of the moving block 43 to avoid insufficient rebound or overshoot. The connecting rope 48 is slidably connected with the guide wheel A 46 and the guide wheel B 47, and the sliding groove 42 and the guide wheel A 46 and the guide wheel B 47 together ensure the correct motion trajectory of the connecting rope 48. The outer wall of the welding box 1 is provided with a movable opening 49, and the connecting rope 48 movably penetrates the movable opening 49.

[0038] In use, when the water storage frame 37 is lowered, the side connecting plate 316 drives the moving block 43 to move outward along the inside of the sliding groove 42 through the action of the connecting rope 48. The key to this action is the sliding connection between the connecting rope 48 and the guide wheel A 46 and the guide wheel B 47, which ensures that the movement direction of the connecting rope 48 is accurately controlled. This control ensures that the moving block 43 can move accurately, and the welding gun 2 moves with the moving block 43 to the edge position of the welding box 1. This action of the welding gun 2 is crucial because it needs to avoid interference from other components during operation, especially when turning over large-size case accessories, to prevent the welding gun 2 from colliding with surrounding objects and causing damage. The sliding system of the connecting rope 48, the accurate guidance of the guide wheels and the flexible design of the moving block 43 effectively avoid this potential problem. When the water storage frame 37 and the side connecting plate 316 are reset, the spring 410 restores the moving block 43 to its original position. Through the elastic force of the spring 410, the moving block 43 can quickly reset, and the welding gun 2 will also return to the welding position. The pre-tightening force of the spring 410 makes the resetting action quick and stable, ensuring that the welding gun 2 can accurately return to the original working position after each operation. This design not only avoids the risk of collision between the welding gun 2 and the case accessories, but also ensures that the equipment can efficiently and safely complete various welding tasks during long-term use. At the same time, the clever cooperation of the spring 410 resetting system and the sliding guide system improves the stability and safety of the operation, further ensuring the reliability of the equipment.

[0039] Embodiment two, please refer to Figures 1-7The cooling assembly 5 comprises a support column 51 fixedly connected to the inside of the welding box 1, a tooth ring 52 fixedly connected to the top of the support column 51, an L-shaped fixed plate 53 fixedly sleeved on the outer wall of the rotating shaft A31, a rotating rod A 54 and a rotating rod B 55 rotatably connected to the inner side of the L-shaped fixed plate 53, a bevel gear A 56 fixedly connected to the other end of the rotating rod A 54, a bevel gear B 57 fixedly sleeved on the outer wall of the rotating rod B 55, a fan blade 59 fixedly connected to the outer wall of the rotating rod A 54, and a transmission gear C 58 movably penetrating through the L-shaped fixed plate 53 and fixedly connected to one end of the rotating rod A 54.

[0040] The bevel gear A 56 and the bevel gear B 57 are engaged, and the transmission gear C 58 is engaged with the tooth ring 52.

[0041] In use, when the rotating shaft A31 rotates, the L-shaped fixed plate 53 fixedly sleeved on the outer wall of the rotating shaft A31 will rotate at any time, thereby driving the rotating rod A 54 and the rotating rod B 55 on the inner side to rotate as a whole. Since the transmission gear C 58 at one end of the rotating rod A 54 is engaged with the tooth ring 52, and the tooth ring 52 does not rotate, the rotating rod A 54 can rotate when the L-shaped fixed plate 53 rotates. The bevel gear A 56 at the other end of the rotating rod A 54 will also rotate at any time, thereby driving the bevel gear B 57 engaged therewith to rotate. The bevel gear B 57 will drive the rotating rod B 55 to rotate, and the rotating rod B 55 will drive the fan blade 59 on the outer wall to rotate, thereby cooling the welding surface. This design can realize synchronous rotation of the fan blade 59 and the welding surface around the rotating shaft A31, so as to ensure that the fan blade 59 is always located above the welding surface and continuously cools the welding surface during the turning process.

[0042] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
