[0028] In order to realize the positioning of the pipeline, two pipeline fixing blocks 6 are also arranged on the top of the base 1, and the two pipeline fixing blocks 6 are symmetrically arranged on both sides of the welding gun 2; the pipeline fixing structure on the pipeline fixing block 6 is as follows: a circular through hole 7 is opened on the surface of each pipeline fixing block 6, and the top and bottom of the circular through hole 7 are penetrated and slidably connected with a straight rod 8, and each straight rod 8 is located at one end of the circular through hole 7 and is fixedly connected with a clamping plate 9, and the two clamping plates 9 are close to each other to realize the clamping of the pipeline; two first cavities 10 are arranged inside the pipeline fixing block 6, and the two first cavities 10 are symmetrically arranged at the top and bottom of the circular through hole 7; one end of the straight rod 8 located in the first cavity 10 is fixedly connected to a No. 1 plate 11, and the No. 1 plate 11 is slidably connected in the first cavity 10; a double-headed screw 12 is penetrated and rotatably arranged on one side of the pipeline fixing block 6, and the two No. 1 plates 11 are respectively sleeved on both ends of the double-headed screw 12;

[0029] When fixing the pipeline, one end of the pipeline is passed through the circular through hole 7, and then the double-headed screw 12 is rotated, so that the double-headed screw 12 drives the two No. 1 plates 11 to slide in the first cavity 10. When the two No. 1 plates 11 are close to each other, the two No. 1 plates 11 will drive the clamping plates 9 to move together through the straight rod 8, so that the two clamping plates 9 can clamp the pipeline, thereby fixing the pipeline, avoiding the change of the position of the pipeline during welding, and the inaccurate welding position, which leads to welding failure;

[0031] Furthermore, in order to enable the two fixed pipes to rotate and enable the welding gun 2 to completely weld the two pipe joints, a structure for driving the pipe fixing block 6 to rotate is also provided on the top of the base 1: a support seat 16 is also symmetrically provided on the top of the base 1, and a cylinder 17 is penetrated and rotatably provided on the support seat 16, both ends of the cylinder 17 are in an open state, and the inner diameter of the cylinder 17 is equal to the diameter of the circular through hole 7, one end of the cylinder 17 is fixedly connected to one side of the pipe fixing block 6, and the pipe is inserted from one end of the cylinder 17 and passes through the circular through hole 7; a mounting hole is provided on the side wall of the support seat 16, and the cylinder 17 is rotatably provided in the mounting hole, and a second cavity 18 is provided inside the support seat 16, and the second cavity 18 Located in the middle of the mounting hole; the cylinder 17 is located in a section of the outer wall of the second cavity 18 and is sleeved and fixedly connected with a gear ring 19, a rotating shaft 20 is penetrated and rotatably arranged on one side of the support seat 16, and the rotating shaft 20 is located in a section of the second cavity 18 and is sleeved and fixedly connected with a gear 21, and the gear 21 and the gear ring 19 are meshed with each other; the rotating shaft 20 is driven by a first motor, and the first motor is fixedly mounted on the side wall of the support seat 16; when it is necessary to rotate the pipe fixing block 6, it is only necessary to start the first motor so that the first motor drives the gear 21 to rotate, and through the cooperation of the gear 21 and the gear ring 19, the cylinder 17 will drive the pipe fixing block 6 to rotate, so that the welding gun 2 can completely weld the annular weld at the butt joint of the two pipes.

[0032] Welding slag is generated during the welding process. In order to collect the welding slag, a rectangular frame 22 is fixedly connected to the top of the base 1, and the rectangular frame 22 is located directly below the welding gun 2.

[0033] See also Figure 6 As shown, a battery pipeline includes a ring structure formed by welding multiple pipes, and the battery pipeline is welded by the above-mentioned welding equipment.

[0034] When the present invention is in use, when fixing the pipeline, first rotate the No. 2 rod 14 downward to ensure that the limit plate 15 is in a vertical downward state, then the pipeline is passed through the circular through hole 7, and one end of the pipeline is against the side wall of the limit plate 15, and then the double-headed screw 12 is rotated, so that the double-headed screw 12 drives the two No. 1 plates 11 to slide in the first cavity 10. When the two No. 1 plates 11 are close to each other, the two No. 1 plates 11 will drive the clamping plates 9 to move together through the straight rod 8, so that the two clamping plates 9 can clamp the pipeline, thereby fixing the pipeline. After fixing one pipeline, the No. 2 rod 14 is rotated upward again, so that the No. 2 rod 14 drives the limit plate 15 to rotate upward, ensuring that the positions of the No. 2 rod 14 and the limit plate 15 will not interfere with the downward movement of the welding gun 2, and then the other pipeline is fixed from the other pipeline fixing block 6. The circular through hole 7 of the support frame 3 is passed through, and one end of the support frame 3 is pressed against one end of the previous pipe, so that the butt joint position of the two pipes is just below the welding gun 2, ensuring the accuracy of the welding position; when the pipe fixing block 6 needs to be rotated, it is only necessary to start the first motor so that the first motor drives the gear 21 to rotate, and through the cooperation of the gear 21 and the gear ring 19, the cylinder 17 drives the pipe fixing block 6 to rotate, so that the welding gun 2 can completely weld the annular weld at the butt joint of the two pipes; during welding, the threaded rod 4 is driven to rotate by the second motor, so that the threaded rod 4 drives the moving seat 5 to slide up and down along the side wall of the support frame 3, so that the welding gun 2 is displaced in the vertical direction, so that the bottom end of the welding gun 2 can contact the butt joint position of the two pipes and realize the welding of the cooling pipe.

[0035] Embodiment 2

[0036] During use of the present invention, in order to ensure that there is sufficient negative pressure inside the welding slag receiving shell 23, the first motor can be installed at the end of the cylinder 17 away from the pipe fixing block 6, and the gear 21 connected to the rotating shaft 20 can be replaced by a speed change gear set engaged with the gear ring 19. Therefore, when the first motor directly drives the pipe fixing block 6 to rotate, so as to achieve the purpose of complete welding of the annular weld at the butt joint of the two pipes by the welding gun 2, the rotating shaft 20 and the fan blades 25 can be accelerated through the engagement between the speed change gear set and the gear ring 19, thereby ensuring that there can be a large negative pressure environment inside the welding slag receiving shell 23, and further improving the collection effect of welding slag.
