The welding of metal products is an important link in industrial production and is widely used in machinery, automobiles, ships, aerospace and other fields;

[0003] In the field of metal welding, one of the key factors for welding quality and efficiency is the accurate adjustment of the welding gun and the metal product, so we need an automatic welding device for metal products;

The outer wall of the rod 10 is slidably connected to the inner wall of the moving frame 8, and the outer wall of the sliding rod 10 is wrapped with an extrusion spring 11. One end of the extrusion spring 11 is fixedly connected to the outer wall of the moving block 9, and the end of the extrusion spring 11 away from the moving block 9 is fixedly connected to the inner wall of the moving frame 8. The outer wall of the moving block 9 is fixedly connected to a limit frame 12, and the limit frame 12 is perpendicular to the outer wall of the moving frame 8. The inner wall of the limit frame 12 is rotatably connected to a rotating roller 13. When in use, the metal product is placed on one side of the rotating roller 13. Under the action of the extrusion spring 11, the rotating roller 13 will fit tightly to the outer wall of the metal product, thereby avoiding welding failure due to the irregular outer wall of the metal product during welding.

[0025] Reference Figure 1-3A slide groove 16 is provided on the top of the moving frame 8, and the slide groove 16 is located at the top central axis of the moving frame 8. A second electric telescopic rod 17 is fixedly connected to the top of the moving frame 8, and the second electric telescopic rod 17 is connected to an external power supply. The telescopic end of the second electric telescopic rod 17 is fixedly connected to a movable frame 18. A connecting column 19 is fixedly connected to the top of the moving block 9, and the connecting column 19 is located inside the movable frame 18. Before placing the metal plate, the second electric telescopic rod 17 is started, and the movable frame 18 is driven by the second electric telescopic rod 17 to shrink. As the movable frame 18 shrinks, the inner wall of the movable frame 18 is connected to the connecting column 19. The outer wall of the connecting column 19 conflicts with the outer wall of the connecting column 19. As time goes by, the second electric telescopic rod 17 will drive the movable frame 18 to drag the connecting column 19 toward the direction of the second electric telescopic rod 17, so that there is enough space to place the metal product. After the metal product is placed, the second electric telescopic rod 17 is started to drive the movable frame 18 to move. As time goes by, the inner wall of the movable frame 18 gradually separates from the outer wall of the connecting column 19, and then under the action of the extrusion spring 11, the moving block 9 drives the rotating roller 13 to move toward the metal product until the outer wall of the rotating roller 13 is tightly fitted with the outer wall of the metal product.

[0026] Reference Figure 1-2 A fixed shell 3 is fixedly connected to the top of the fixed frame 2, and the fixed shell 3 is located at the top center of the fixed frame 2. A driving motor 4 is fixedly connected to the inner wall of the fixed shell 3, and the driving motor 4 is connected to an external power supply. A threaded column 5 is fixedly connected to the output end of the driving motor 4, and the outer wall of the threaded column 5 is threadedly connected to the inner wall of the limit block 7. During welding, the driving motor 4 is started, and the threaded column 5 is driven by the driving motor 4 to rotate. When the threaded column 5 rotates, it will drive the limit block 7 to reciprocate along the threaded column 5, thereby welding metal products of different heights and improving the versatility of use of the equipment.

[0027] Reference Figure 1-3 The outer side wall of the moving block 9 is fixedly connected with a first electric telescopic rod 14, which is connected to an external power supply. The telescopic end of the first electric telescopic rod 14 is fixedly connected with a welding gun 15. When welding, the first electric telescopic rod 14 is started, and the welding gun 15 is driven by the first electric telescopic rod 14 to move, so that the position of the welding gun 15 is adjusted according to the distance between the weld of the metal product and the welding gun 15, thereby improving the welding efficiency of the equipment.

[0028] Reference Figure 1A fixing plate 20 is fixedly connected to the top of the bottom plate 1, and a third electric telescopic rod 21 is fixedly connected to the outer wall of the fixing plate 20. The third electric telescopic rod 21 is connected to an external power supply. A clamping plate 22 is fixedly connected to the telescopic end of the third electric telescopic rod 21, and a rubber pad is provided on the outer wall of the clamping plate 22. When the third electric telescopic rod 21 drives the clamping plate 22 to contact the outer wall of the metal product, the rubber pad provided on the outer wall of the clamping plate 22 contacts the outer wall of the metal product, thereby increasing the friction between the clamping plate 22 and the metal product and improving the stability of the metal product during welding.

[0029] Working principle: When welding metal products, start the second electric telescopic rod 17, and the second electric telescopic rod 17 drives the movable frame 18 to move. During the movement of the movable frame 18, pull the connecting column 19 to increase the distance between the two moving blocks 9. At this time, place the metal plate between the two rotating rollers 13, start the third electric telescopic rod 21, and push the clamping plate 22 to fix the two metal products. After the fixation is completed, continue to start the second electric telescopic rod 17, and the second electric telescopic rod 17 pushes the movable frame 18 to gradually move away from the connecting column 19, so that under the action of the elastic force of the extrusion spring 11 itself, the movable block 9 is pushed to drive the rotating roller 13 to move, so that the outer wall of the rotating roller 13 is closely fitted with the outer wall of the metal product, and the first electric telescopic rod 14 is started, and the first The electric telescopic rod 14 drives the welding gun 15 to move. When the welding gun 15 moves to the connection point of the two metal products and stops, one end of the welding gun 15 is aligned with the gap between the metal products. After the preparation work is ready, the welding gun 15 is started, and the two metal products are welded by the welding gun 15. During the welding process, the driving motor 4 is started, and the driving motor 4 drives the threaded column 5 to rotate, thereby driving the limit block 7 and the moving frame 8 to move up and down. During the movement, since the extrusion spring 11 itself has elastic force, the rotating roller 13 will always be tightly attached to the outer wall of the metal product under the action of the extrusion spring 11, thereby avoiding the change of the distance between the welding gun 15 and the metal product due to the irregular outer wall of the metal product during the welding process, thereby avoiding welding failure or defects in the weld.
