Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 4 A welding device for thin-walled aluminum plates, comprising a welding machine 1, an aluminum plate body 8, and a welding gun body 5. The welding gun body 5 is mounted on a lifting plate 4, and the lifting plate 4 is connected to a lifting mechanism 3 for driving it to move up and down. The lifting mechanism 3 is mounted on a moving mechanism 2, and the moving mechanism 2 is used to drive the lifting mechanism 3 to move along the trajectory of the connecting line of the two aluminum plate bodies 8. The moving mechanism 2 is composed of a guide rail, a lead screw, etc., and can drive the lifting mechanism 3 and the welding gun body 5 to move along the straight line of the splicing of the two aluminum plate bodies 8. The welding gun body 5 welds the two aluminum plate bodies 8 spliced ​​together; the thickness of the thin aluminum plate is between 0.2mm-4.0mm, and the strength of the two thin aluminum plates welded on one side is poor. In some use areas with high strength requirements, double-sided welding is required;

[0024] Furthermore, the two aluminum plate bodies 8 are respectively installed in the storage slots in the two flip frames 6, and a gap is set between the two flip frames 6, and the gap can allow the welding wire and the nozzle of the welding gun body 5 to enter, so that after the flip frame 6 is flipped, the welding wire and the nozzle can reach the welding position between the two aluminum plate bodies 8, and the two flip frames 6 are symmetrically distributed about the center line of the connection position of the two aluminum plate bodies 8. The flip frame 6 is connected to a flip motor 7 that can drive the flip frame 6 to flip 180° in a single time. The flip frame 6 is inserted into the flip groove, and the flip frame 6 is rotatably connected to the inner wall of the flip groove. The flip groove is set on the welding machine 1, and the flip motor 7 can drive the flip frame 6 to rotate 180 degrees, so that the connection line originally facing the lower side of the connection between the two aluminum plate bodies 8 is facing the upper side, and this side is welded by the welding gun body 5, so that the welding work of the two sides of the aluminum plate body 8 can be realized;

[0025] Furthermore, a pressing plate 9 is installed on the flip frame 6, and the pressing plate 9 is connected to an opening and closing mechanism. The opening and closing mechanism allows the pressing plate 9 to have at least two states, wherein the two states are a clamping state and an opening state. In the clamping state, the pressing plate 9 is pressed on a side of the aluminum plate body 8 that is not in contact with the inner wall of the storage tank. In the opening state, the pressing plate 9 does not hinder the up and down movement of the aluminum plate body 8. When the aluminum plate loading and unloading device (not shown in the figure) loads and unloads, a straight up and down method is adopted. The opening and closing mechanism connected to the pressing plate 9 allows it to not hinder the loading and unloading of the upper and lower devices, and at the same time completes the clamping work of the aluminum plate body 8.

[0026] Specifically, the opening and closing mechanism includes an opening and closing motor, the opening and closing motor is connected to a rotating shaft, the rotating shaft is fixedly connected to a pressing plate 9 arranged in an L shape, and the rotating shaft is rotatably connected to a flip frame 6;

[0027] In order to remove welding slag and the like generated on the other side of the aluminum plate body 8 after single-sided welding, a grinding frame 10 is hinged on the lifting plate 4, and the grinding frame 10 is connected to the extension and contraction mechanism 12. A grinding mechanism 11 is installed on the grinding frame 10. The grinding frame 10 connected to the extension and contraction mechanism 12 has at least two states, wherein the two states are an extension state and a contraction state. In the extension state, the grinding frame 10 and the grinding mechanism 11 rotate to the lower side of the welding gun body 5. When the lifting mechanism 3 drives the lifting plate 4 to move downward, the grinding mechanism 11 contacts the aluminum plate body 8 first to grind the connection. In the contraction state, the height of the lowest point of the grinding frame 10 is higher than the height of the lowest point of the welding gun body 5. In the contraction state, the welding work of the welding gun body 5 will not be hindered.

[0028] Working principle:

[0029] When the utility model is used, the two aluminum plate bodies 8 are transported to the two turning frames 6 driven by the aluminum plate loading and unloading device (not shown in the figure), the opening and closing mechanism is started to drive the pressing plate 9 to rotate, and the two aluminum plate bodies 8 are pressed tightly, and the lifting mechanism 3 is started to drive the welding gun body 5 to move downward to align with the connection position of the two aluminum plate bodies 8, and the welding gun body 5 is driven to move by the moving mechanism 2 to perform single-sided welding on the entire connection position. After the single-sided welding is completed, the lifting mechanism 3 drives the welding gun body 5 to move upward, and the extension and contraction mechanism 12 drives the grinding frame 10 and the grinding mechanism 11 to rotate, and rotate to the extended state;

[0030] The turning motor 7 drives the turning frame 6 and the aluminum plate body 8 to turn 180 degrees, the lifting mechanism 3 drives the lifting plate 4 and the grinding frame 10 to move downward, the moving mechanism 2 drives the grinding mechanism 11 to move, and grinds the aluminum plate body 8, and the stretching and contracting mechanism 12 drives the grinding frame 10 to rotate to a contracted state;

[0031] The lifting mechanism 3 drives the welding gun body 5 to move downward to weld the other side of the aluminum plate body 8. After the moving mechanism 2 drives the welding gun body 5 to move, the lifting mechanism 3 moves the welding gun body 5 to the initial position, and the flip motor 7 rotates the flip frame 6 and the aluminum plate body 8 one hundred and eighty degrees, and the aluminum plate loading and unloading device takes away the welded aluminum plate body 8.
