Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3The present invention provides an automatic sheet metal welding device, comprising: a base plate 1 and a support plate 2 installed on one end of the top outer wall of the base plate 1; further comprising: a rotary cylinder 3 rotatably installed on one side outer wall of the support plate 2; a circular plate 4 installed on one end of the rotary cylinder 3; a plurality of equally spaced slots 6 opened on one side outer wall of the circular plate 4; a limit assembly 7 slidably connected to the inner wall of the slots 6; a conductive slip ring 8 and a toothed ring 9 installed on the outer wall of the rotary cylinder 3; an adjustment assembly 5 installed on one side inner wall of the rotary cylinder 3; a first motor 10 installed on one side outer wall of the support plate 2; a gear 11 installed on one end of the output shaft of the first motor 10; an electric slide table 12 installed on the top outer wall of the base plate 1; a mounting frame 13 installed on the top of the sliding part of the electric slide table 12; and welding assembly 14 and grinding assembly 15 respectively installed on the upper and lower inner walls of the mounting frame 13.

[0019] It should be noted that: short sheet metal fittings can be fitted onto the outside of one end of multiple limiting components 7, connecting these sheet metal fittings end to end. At this time, the adjusting component 5 can drive multiple limiting components 7 to expand outward simultaneously, supporting and fixing the sheet metal fittings from the inner wall, and ensuring that the center points of these sheet metal fittings are all on a center line. Fixing and aligning the sheet metal fittings is convenient and quick. The electric slide table 12 can drive the mounting bracket 13 to move, thereby adjusting the position of the welding component 14 and the grinding component 15, and thus adjusting the welding position. After adjusting to the required welding position, the first motor 10 can drive the gear 11 to rotate, thereby driving the gear ring 9 and the rotating cylinder 3 to rotate, and thus driving the sheet metal fitting to rotate, facilitating welding of the arc-shaped outer wall of the sheet metal fitting. Before welding, the outer wall of the sheet metal fitting at the welding point can be ground by the grinding component 15 to remove impurities on the surface of the sheet metal fitting, preventing impurities from causing defects such as porosity and slag inclusions during the welding process, which helps to improve the welding effect. After grinding, the welding component 14 can be used to perform welding.

[0020] In a preferred embodiment, the adjusting component 5 includes a first electric push rod 501, a hexagonal block 502 mounted on one end of the piston rod of the first electric push rod 501, and a plurality of connecting rods 503 rotatably mounted on the outer wall of the hexagonal block 502 and distributed at equal intervals; the limiting component 7 includes a slider 701, a limiting plate 702 mounted on one side of the outer wall of the slider 701, and a limiting block 703 mounted on the outer wall of the limiting plate 702.

[0021] It should be noted that the first electric push rod 501 can push the hexagonal block 502 to move, which in turn pushes the slider 701 to move through the connecting rod 503, thereby driving the limit plate 702 to move.

[0022] In a preferred embodiment, the end of the connecting rod 503 away from the hexagonal block 502 is rotatably connected to the outer wall of one side of the slider 701.

[0023] It should be noted that the hexagonal block 502 can be moved by pushing the slider 701 through the connecting rod 503.

[0024] In a preferred embodiment, the welding assembly 14 includes a second electric push rod 1401 and a welding gun 1402 mounted on the bottom of the piston rod of the second electric push rod 1401.

[0025] It should be noted here that the second electric push rod 1401 can drive the welding gun 1402 to descend and contact the sheet metal fitting for welding.

[0026] In a preferred embodiment, the grinding assembly 15 includes a third electric push rod 1501, a fixed frame 1502 mounted on the top of the piston rod of the third electric push rod 1501, a grinding wheel 1503 rotatably mounted on the inner wall of the fixed frame 1502, and a second motor 1504 mounted on the outer wall of one side of the fixed frame 1502.

[0027] It should be noted here that: the third electric push rod 1501 can drive the grinding wheel 1503 to rise and contact the sheet metal pipe, and the second motor 1504 drives the grinding wheel 1503 to rotate to grind the sheet metal pipe.

[0028] Working principle: Short sheet metal fittings can be fitted over multiple limiting plates 702, connecting the ends of these sheet metal fittings. Then, the first electric push rod 501 can push the hexagonal block 502 to move, and then multiple connecting rods 503 can simultaneously push multiple sliders 701 to move, thereby causing multiple limiting plates 702 to expand outward at the same time, supporting and fixing the sheet metal fittings from the inner wall, and ensuring that the center points of these sheet metal fittings are all on the same center line, making the fixing and alignment of the sheet metal fittings convenient and quick.

[0029] The mounting bracket 13 can be moved by the electric slide table 12, thereby adjusting the position of the welding gun 1402 and the welding position. After adjusting to the required welding position, the gear 11 can be rotated by the first motor 10, which in turn rotates the gear ring 9 and the rotating drum 3, thereby rotating the sheet metal fitting. This facilitates welding of the arc-shaped outer wall of the sheet metal fitting. Before welding, the grinding wheel 1503 can be raised by the third electric push rod 1501 to contact the sheet metal fitting. The grinding wheel 1503 is rotated by the second motor 1504 to grind the sheet metal fitting, removing impurities from the surface of the sheet metal fitting. This prevents impurities from causing defects such as porosity and slag inclusions during welding, which helps to improve the welding effect. After grinding, the grinding wheel 1503 is lowered and reset by the third electric push rod 1501, and the welding gun 1402 is lowered by the second electric push rod 1401 to contact the sheet metal fitting for welding.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
