Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 7 As shown, the present invention provides a stainless steel coil round welding device, comprising a workbench 1, the left and right ends of the workbench 1 are slidably connected with a gantry 2 located at the top of the workbench 1, an electric push rod 3 is fixedly installed at the top of the gantry 2, a moving plate 4 is fixedly installed on the output shaft of the electric push rod 3, and a steel coil body 33 is arranged at the top of the workbench 1;

[0029] A cleaning mechanism is arranged at the front and rear ends of the movable plate 4, and the cleaning mechanism includes a fixed shell 6, which is fixedly connected to the front and rear ends of the movable plate 4, and a welding gun 5 is arranged at the bottom end of the movable plate 4 and is located on the opposite side of the fixed shell 6, and a connecting plate 7 is slidably connected inside the fixed shell 6, and a fixed plate 8 is fixedly installed at the bottom end of the connecting plate 7, and a spring 9 is fixedly installed at the bottom end of the fixed plate 8, and a square shell 10 is fixedly installed at the bottom end of the spring 9, and a frosting plate 11 is arranged inside the square shell 10, and a fixed box 12 is fixedly installed at the top of the movable plate 4, and an inner gear ring 13 located inside the fixed box 12 is slidably connected inside the movable plate 4, and one side of the top of the connecting plate 7 extends to the inside of the fixed box 12 and is fixedly connected to both sides of the inner gear ring 13, and a motor 14 is fixedly installed at the top of the fixed box 12, and the output end of the motor 14 extends to the inside of the fixed box 12 and is fixedly installed with a half gear 15 meshing with the inner gear ring 13.

[0030] The above scheme is adopted: the operator places the steel coil body 33 on the top of the workbench 1, and then drives the extrusion mechanism to extrude the steel coil body 33, and then aligns the welding seam at the top of the steel coil body 33, and then the electric push rod 3 can be driven, and then the output shaft of the electric push rod 3 will push the moving plate 14 to descend, and then the moving plate 14 will drive the welding gun 5 to descend, and then the bottom end of the frosting plate 11 will contact the welding seam at the top of the steel coil body 33, and then the frosting plate 11 and the square shell 10 will move up, and then the frosting plate 11 will squeeze the spring 9, and through the compression of the spring 9, the frosting plate 11 can be tightly attached to the welding seam at the top of the steel coil body 33, and then the bottom end of the welding gun 5 will contact the welding seam, and then the welding gun 5 can be driven to perform round welding on the steel coil body 33, and then the gantry 2 can be driven to move, and then the gantry 2 will drive the welding gun 5 to move, and through the movement of the welding gun 5, the entire surface of the steel coil body 33 is round welded;

[0031] During the welding process, the motor 14 can be driven to rotate the half gear 15, because the half gear 15 is meshed with the inside of the inner gear ring 13, and the half gear 15 is designed as a half gear, and when the half gear 15 rotates, it will drive the inner gear ring 13 to move back and forth, and then the inner gear ring 13 will drive the connecting plate 7 and the fixed plate 8 to move back and forth, and then the fixed plate 8 will drive the square shell 10 and the frosting plate 11 to move. Since the bottom end of the frosting plate 11 is in contact with the welding seam of the steel coil body 33, and the bottom end of the frosting plate 11 is rough in design, the oxide around the welding point can be cleaned, thereby increasing the aesthetics of the welding of the steel coil body 33. When the gantry 2 moves, the cleaning mechanism will move with it, and the surface of the steel coil body 33 can be cleaned while the welding gun 5 is welding.

[0032] like Figure 5 and Figure 6 As shown, it also includes: an extrusion mechanism, which is arranged inside the workbench 1, and the extrusion mechanism includes a motor 22, the motor 22 is fixedly connected to the bottom end inside the workbench 1, and the output end of the motor 22 is fixedly installed with a screw rod 23, and the surface of the screw rod 23 is threadedly connected with a moving plate 24, and the top of the moving plate 24 is provided with an extrusion groove 25, and the inside of the extrusion groove 25 is slidably connected with a moving block 26, and the top of the moving block 26 is fixedly installed with a connecting block 27, and the bottom end of the connecting block 27 is fixedly installed with an extrusion plate 28, and a protective plate 29 is fixedly installed on the opposite side of the extrusion plate 28.

[0033] The above scheme is adopted: through the extrusion mechanism design, after the steel coil body 33 is placed on the top of the workbench 1, the motor 22 can be driven to rotate the screw rod 23. Since the screw rod 23 is threadedly connected to the movable plate 24, when the screw rod 23 rotates, the movable plate 24 will move. During the movement of the movable plate 24, the movable block 26 will move inside the extrusion groove 25. Since the extrusion groove 25 has an inclined design, the movable block 26 will move relatively, and then the movable block 26 will drive the connecting block 27 to move relatively, and then the movable block 26 will drive the extrusion plate 28 and the protective plate 29 to move relative, and then the surface of the protective plate 29 will contact the surface of the steel coil body 33, and then it will squeeze the surface of the steel coil body 33, and then the two ends of the steel coil body 33 will move relatively, and then the two ends of the steel coil body 33 will be aligned, and then the connection can be round welded.

[0034] like Figure 7 As shown, a magnet 2 17 is installed at the top of the square shell 10, a magnet 16 is fixedly installed at the top of the frosting plate 11, and a slide groove 18 is opened at both ends of the fixed shell 6. A slider 19 is slidably connected inside the slide groove 18, and the opposite sides of the slider 19 are in contact with the two ends of the connecting plate 7.

[0035] The above scheme is adopted: through the design of magnet one 16 and magnet two 17, when the frosting plate 11 is placed inside the square shell 10, magnet one 16 and magnet two 17 will contact each other, and then the frosting plate 11 can be fixed inside the square shell 10 through the principle of opposites attracting each other; through the design of magnet two 17 and slide groove 18, when the connecting plate 7 moves, the connecting plate 7 will drive the slider 19 to move inside the slide groove 18, and since the surface of the slider 19 contacts the inside of the slide groove 18, the slider 19 will support the connecting plate 7.

[0036] like Figure 4 and Figure 5 As shown, a fixing groove 20 is provided at the top of the movable plate 4, and the interior of the fixing groove 20 is slidably connected to a limiting block 21, and the top of the limiting block 21 is fixedly connected to the bottom end of the inner gear ring 13; a limiting rod 30 is fixedly installed inside the workbench 1, and the surface of the limiting rod 30 is slidably connected to a limiting block 2 31, and the top of the limiting block 2 31 is fixedly connected to the bottom end of the extrusion plate 28, and the surface of the limiting rod 30 is designed to be smooth.

[0037] The above scheme is adopted: through the design of the fixed groove 20 and the limit block 1 21, when the inner gear ring 13 moves back and forth, the limit block 1 21 will move inside the fixed groove 20, and then the limit block 1 21 can limit the movement trajectory of the inner gear ring 13; through the design of the limit rod 30 and the limit block 2 31, when the extrusion plate 28 moves, the limit block 2 31 will move on the surface of the limit rod 30, and then the limit block 2 31 will limit the extrusion plate 28, thereby ensuring the smooth movement of the extrusion plate 28.

[0038] like Figure 2 As shown, a positioning groove is provided in the middle of the top of the workbench 1, and the positioning groove is arc-shaped, the surface of the steel coil body 33 is fitted with the inner wall of the positioning groove, the extrusion plate 28 and the protective plate 29 are symmetrically designed about the center of the workbench 1, and the protective plate 29 is made of rubber material and fits with the surface of the steel coil body 33.

[0039] The above scheme is adopted: through the design of the workbench 1, the steel coil body 33 can be placed inside the positioning groove. Since the positioning groove is designed to be arc-shaped, the steel coil body 33 can be positioned, thereby increasing the welding effect of the device; through the design of the extrusion plate 28 and the protective plate 29, when the protective plate 29 squeezes the steel coil body 33, since the protective plate 29 is made of rubber material, the protective plate 29 will be deformed during the extrusion process, thereby protecting the steel coil body 33 and preventing the steel coil body 33 from being deformed during the extrusion process.

[0040] like Figure 1 As shown, a support leg 32 is fixedly installed at the bottom end of the workbench 1. There are four support legs 32, which are evenly distributed at the bottom end of the workbench 1. Square holes are opened at the front and rear ends of the fixed box 12, and the connecting plate 7 can move inside the square holes.

[0041] The above scheme is adopted: through the design of the support legs 32, when the device is working, the support legs 32 can support the device, thereby increasing the stability of the device; through the design of the fixed box 12, when the connecting plate 7 moves, it will move inside the square hole, and thus the fixed box 12 will not interfere with the reciprocating movement of the connecting plate 7.

[0042] The working principle and use process of the present invention:

[0043] First, the operator can place the steel coil body 33 inside the positioning groove in the middle of the workbench 1, and then drive the motor 22 to rotate the screw rod 23, and then the moving plate 24 will move on the surface of the screw rod 23, and then the extrusion groove 25 will move, and then the extrusion groove 25 will squeeze the moving block 26, and then the moving block 26 will move relatively inside the extrusion groove 25, and then the moving block 26 will drive the connecting block 27 to move relatively, and then the connecting block 27 will drive the extrusion plate 28 and the protective plate 29 to move relatively, and then the surface of the protective plate 29 will contact the surface of the steel coil body 33, and then it will squeeze the steel coil body 33, and then the two ends of the steel coil body 33 will contact and align;

[0044] After the contact alignment, the electric push rod 3 can be driven to lower the moving plate 4, and then the frosting plate 11 will contact the steel coil body 33, and the square shell 10 will squeeze the spring 9, and then the bottom end of the welding gun 5 will contact the connection of the steel coil body 33, and then the welding gun 5 can be driven to weld the steel coil body 33. During the welding process, the gantry 2 can be driven to move the welding gun 5 and the frosting plate 11. When the welding gun 5 moves, the motor 14 can be driven to rotate the half gear 15, and then the half gear 15 will drive the inner gear ring 13 to reciprocate, and then the inner gear ring 13 will drive the connecting plate 7 and the fixed plate 8 to reciprocate, and then the fixed plate 8 will drive the spring 9, the square shell 10 and the frosting plate 11 to reciprocate. During the movement of the frosting plate 11, the oxide on the surface of the steel coil body 33 is cleaned, and finally the operation process is completed.
