Compared with the existing single-sided welding equipment of the manipulator, it has low cost and high welding efficiency, and can weld the partitions 41 on both sides at the same time. When flipping, it only rolls with the axis of the oil tank 4 as the center. The space required for flipping is small. Compared with the flipping of existing equipment, it can better protect the surface of the oil tank 4.

[0036] like Figure 3 As shown, the flip assembly includes a slewing bearing 32 fixed to the side of the mounting seat 31, and the clamping assembly is installed on the outer ring of the slewing bearing 32, including a symmetrically arranged support plate 33, a slide rail 34 is fixed on the support plate 33, and a sliding plate 35 is slidably connected to the slide rail 34 through a slider, and a push-pull clamp 36 is also fixed on the support plate 33. The push-pull clamp 36 is composed of a handle, a connecting rod and a push rod. The extension length of the push rod is controlled by the swing of the handle so that the push rod is against the sliding plate 35. The push-pull clamp 36 is located on one side of the sliding plate 35, further pushing the sliding plate 35 to slide on the slide rail 34 to control the position of the sliding plate 35. The push-pull clamp 36 is used to resist the sliding plate 35 to control its position. Clamps 37 are also symmetrically installed at both ends of one side of the sliding plate 35, so that the clamps 37 move forward to resist the side of the oil tank 4, and the clamps 37 on both sides are simultaneously attached to the side of the oil tank 4 to clamp the oil tank 4.

The steering plate 310 The rotation causes the first connecting rod 39 and the second connecting rod 311 to move in opposite directions, and the sliding plate 35 moves inward along the sliding rail 34, which will push the connecting plate 38 to move inward, causing the first connecting rod 39 to move inward, further pushing the steering plate 310 to rotate, driving the second connecting rod 311 at the other end of the steering plate 310 to move inward, and further causing the sliding plate 35 on the other side to move inward, pushing the clamping claw 37 on the other side to move inward synchronously, so that the two sides can clamp the oil tank 4 synchronously, and the clamping claws 37 on both sides are linked, thereby improving the convenience of clamping the oil tank 4.

[0038] like Figure 3 and 4 As shown, a servo motor 313 is also fixed on the mounting seat 31, and a gear is fixed on the servo motor 313. The gear is meshed with the outer surface of the slewing bearing 32. The rotation of the servo motor 313 causes the gear to rotate, and further causes the outer ring of the slewing bearing 32 to rotate, thereby realizing the flipping of the clamped oil tank 4, so that the welding gun mechanism 2 can weld a circle of the partition 41, and the support plate 33, the slide rail 34, the sliding plate 35, the push-pull clamp 36, the clamp 37 and the connecting plate 38 also rotate with the outer ring of the slewing bearing 32, so that the clamp 37 always clamps the oil tank 4 when flipping.

[0040] The mounting seat 31 can also be pushed by a cylinder. A cylinder is installed on the base 1, and the telescopic end of the cylinder is connected to the side of the mounting seat 31.

The circular handle 67 controls the distance between the limit seat 66 and the mounting seat 31, that is, the distance between the clamping position of the clamping assembly and the end face of the oil tank 4. The movement of the linear slider 65 will drive the movable plate 63 and the telescopic cylinder 64 to move, thereby controlling the clamping position of the clamping assembly on the oil tank 4. Subsequently, the extension and retraction of the telescopic cylinder 64 will turn the limit seat 66 to avoid interference between the limit seat 66 and the welding gun 27. A guide rod 62 is also fixed to the limit frame 61, and the movable plate 63 is slidably connected to the guide rod 62. The guide rod 62 is used to guide the sliding of the movable plate 63.

The mounting rod 26 is fixed on the slider of the fourth module 25, and the welding gun 27 is fixed on the mounting rod 26. The position of the welding gun 27 on the XYZ three axes is controlled by the cooperation of the first module 22, the fourth module 25, the second module 23 and the third module 24, so that the welding gun 27 can weld oil tanks 4 of different specifications. A laser tracker is installed on the welding gun 27. The laser tracking device is formed by the cooperation of the third module 24, the fourth module 25 and the welding gun 27 to fine-tune the position of the welding gun 27 so that the welding gun 27 is always attached to one circle of the partition 41.

[0043] The sides of the second module 23 and the third module 24 are fixed with load-reducing cylinders 232, and the two groups of load-reducing cylinders 232 are respectively connected to the connecting seat 231 and the fourth module 25, so the welding gun 27 is installed on the mounting rod 26, and the mounting rod 26 is long, so that the fourth module 25 has a large load-bearing capacity and the load-bearing capacity is all located on one side, and the third module 24 and the fourth module 25 are connected to the second module 23 at the same time, and the load on the slider of the second module 23 is also too large, so the telescopic end is connected to the connecting seat 231 and the fourth module 25 through the load-reducing cylinder 232, so that the connecting seat 231 and the fourth module 25 are subjected to an upward pulling force, reducing the load-bearing capacity on the fourth module 25 and the second module 23, so that the linear module runs more smoothly, and at the same time the load-reducing cylinder 232 can also balance the fourth module 25 to prevent it from being deflected by force.

[0044] like Figure 5As shown, an oil tank lifting mechanism 5 is also arranged between the two oil tank clamping and flipping mechanisms 3. The oil tank lifting mechanism 5 is fixed on the base 1.

A fork rod mounting rod 54 is connected to the side of the lifting plate 52. A fork rod 55 is fixed on the fork rod mounting rod 54. The fork rod 55 is used to lift the oil tank 4. The lifting and lowering of the lifting cylinder 53 drives the lifting plate 52 to move up and down, and further controls the fork rod mounting rod 54 and the fork rod 55 to move up and down, so as to control the height of the oil tank 4.

[0045] A screw rod 58 is threadedly connected to the middle of the top wall of the bracket 51, and a limit plate 59 is threadedly connected to the screw rod 58.

[0047] The welding process of the oil tank partition is as follows: the oil tank 4 is first placed on the oil tank lifting mechanism 5, and the bottom plate 57 and the pads 56 on both ends thereof are moved along the X-axis by the extension and contraction of the moving cylinder 514 to drive the oil tank 4 to move, and the center of the oil tank 4 is adjusted so that the central axis of the oil tank 4 and the center of the oil tank clamping and flipping mechanism 3 are on the same plane, and then the fork rod 55 is driven upward by the lifting cylinder 53 to control the height of the oil tank 4 so that the axis of the oil tank 4 and the centers of the oil tank clamping and flipping mechanisms 3 at both ends are on the same straight line, so that the oil tank clamping and flipping mechanisms 3 can move left and right to clamp the oil tank 4;

[0048] Then move the welding gun mechanism 2 so that the welding guns 27 on both sides are located at the junction of the partition 41 and the oil tank 4, and the welding guns 27 are always facing downward, so that only the edge of the lower end of the partition 41 can be welded.
