[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

A bidirectional threaded rod 4 is rotatably connected between the left and right inner walls of the first rectangular inner groove 2, and the thread directions of the two threaded ends of the bidirectional threaded rod 4 are opposite. The right end of the bidirectional threaded rod 4 passes through the right inner wall of the first rectangular inner groove 2 and is fixedly connected to the output shaft of the first motor 3. The two threaded ends of the bidirectional threaded rod 4 are both threadedly connected with a first connecting block 5, and the two first connecting blocks 5 are slidably connected to the inner wall of the first rectangular inner groove 2;

[0021] Among them, it also includes a rotation limiting mechanism, which is used to limit and rotate the welding plate. The rotation limiting mechanism includes a second motor 6, which is installed on the left side of the first connecting block 5 located on the left side. The opposite sides of the two first connecting blocks 5 are rotatably connected with a rotating shaft 7. The left end of the rotating shaft 7 located on the left side passes through the corresponding first connecting block 5 and is fixedly connected to the output shaft of the second motor 6. The opposite ends of the two rotating shafts 7 are fixedly connected with a second connecting block 8. The opposite sides of the two second connecting blocks 8 are horizontally provided with second rectangular inner grooves 9, and the inner tops of the two second rectangular inner grooves 9 are provided with A clamping plate 10 that can move up and down is provided, and the clamping plate 10 can limit the side reinforcing plate. The upper ends of the two second connecting blocks 8 are provided with threaded grooves, and the two threaded grooves are threadedly connected to limit screws 11. The lower ends of the two limit screws 11 penetrate the corresponding threaded grooves and are rotatably connected to the upper ends of the corresponding clamping plates 10. The rear sides of the two second connecting blocks 8 are fixedly connected with connecting plates 12, and the right end of the connecting plate 12 on the left is fixedly connected with a connecting rod 13, and the right end of the connecting rod 13 penetrates the connecting plate 12 on the right, and the two second connecting blocks 8 can be ensured to rotate synchronously through the connecting rod 13;

[0022] Among them, it also includes a cooling mechanism, which is used to accelerate the cooling rate of the plate welding point. The cooling mechanism includes an air pump 14 installed on the upper end of the base 1, and two telescopic rods 15 are symmetrically installed on the base 1. The two telescopic rods 15 are electric telescopic rods. The telescopic ends of the two telescopic rods 15 are commonly fixedly connected with a third connecting block 16, and a cooling cavity is opened in the third connecting block 16. The inner top of the cooling cavity is opened with a plurality of air outlets 18. The air outlet end of the air pump 14 is connected with a hose 17, and the other end of the hose 17 is connected with the cooling cavity. The left and right sides of the third connecting block 16 are fixedly connected with L-shaped connecting blocks 19. When the telescopic ends of the two telescopic rods 15 are pulled to the maximum height, the upper ends of the two L-shaped connecting blocks 19 are in the same horizontal plane with the inner bottoms of the two second rectangular inner grooves 9. At this time, the side reinforcement plate can be supported.

[0023] In the utility model, when in use, first control the two telescopic rods 15 to drive the third connecting block 16 to move up, drive the two L-shaped connecting blocks 19 to move up to the top, and then place a side reinforcing plate in the second rectangular inner groove 9 on the left side.

During the rotation process, the second connecting block 8 will drive the second connecting block 8 on the right to rotate through the connecting rod 13, thereby driving the two side reinforcing plates to rotate 180° in the same direction at the same time, effectively avoiding damage to the previous welding position during the rotation process, and then the two telescopic rods 15 are controlled again to drive the third connecting block 16 to move upward to the top, and the air pump 14 is started, so that the gas enters the cooling chamber through the hose 17 and finally sprays upward through the multiple air outlets 18, so that the gas can be discharged from the previous welding position, effectively improving the cooling rate of the plate welding position, and at the same time, the upper end portion of the two side reinforcing plates can be welded at this time. After welding is completed, refer to the above operation and then rotate the welding position 180° for cooling. The whole welding process is simple and fast, and the actual welding efficiency is effectively improved by cooling while welding.
