[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0018] As Figures 1 - 10 shown, an automatic argon arc welding machine for improving the welding accuracy of aluminum single plates includes a base 1. The upper surface of the base 1 is rotatably connected to a processing table 2 through a lifting mechanism. On both sides of the upper surface of the base 1, side plates 3 are respectively fixedly connected. A blocking plate 26 is rotatably installed between the two side plates 3 through a driving mechanism. The front surface of the blocking plate 26 is connected to a pressure strip 31 through a vertical elastic mechanism. On the side surfaces of the two side plates 3 close to each other, curve guiding parts are respectively arranged. The two ends of the pressure strip 31 are respectively connected to guide rollers 36 through horizontal elastic mechanisms, and the guide rollers 36 are located inside the curve guiding parts. A limit block 15 is slidably inserted into one side surface of the side plate 3 through a telescopic mechanism, and an argon arc welding mechanism is arranged at the lower end of the limit block 15; As Figure 8 shown, it is an aluminum single plate after sheet metal processing, which has a bottom inclined plate 42. The front and rear edges of the bottom inclined plate 42 are integrally connected to a long plate 43 and a short plate 44 respectively. The two side edges of the bottom inclined plate 42, the long plate 43 and the short plate 44 are respectively vertically folded.

[0019] For the height setting of the blocking plate 26, the following conditions need to be met: when the aluminum single plate slides down obliquely along the surface of the processing table 2, the upper edge of the long plate 43 of the aluminum single plate is blocked by the blocking plate 26, and the short plate 44 of the aluminum single plate passes under the blocking plate 26.

[0020] As Figure 5 、 Figure 6As shown, the curve guiding part includes a major arc plate 21 fixedly connected to the side surface of the side plate 3. The lower rear end of the major arc plate 21 is fixedly connected with a curved guide plate 22. The lower end of the curved guide plate 22 is fixedly connected with a lower guide plate 23. The lower front end of the major arc plate 21 is fixedly connected with an upper guide plate 20. A through hole 19 is formed through the side surface of the side plate 3. The limiting block 15 slides through the inside of the through hole 19. A notch 16 is formed on one side surface of the limiting block 15, and the upper guide plate 20 is located on one side of the notch 16. The notch 16 provides a reserved space. When the limiting block 15 moves horizontally, the notch 16 will relatively sleeve on the outside of the upper guide plate 20.

[0021] As Figure 3 , Figure 4 shown, the telescopic mechanism includes a fixed plate 4 fixedly connected to the lower end of the side plate 3. A telescopic cylinder 5 and a guide cylinder 6 are fixedly penetrated through one side surface of the fixed plate 4. A guide rod 7 is slidably inserted into the port of the guide cylinder 6. One end of the guide rod 7 and the telescopic end of the telescopic cylinder 5 are fixedly connected with a moving plate 8 together. There is an elastic connection between the upper end of one side surface of the moving plate 8 and the limiting block 15. When the telescopic cylinder 5 expands and contracts, the guide rod 7 will slide relatively along the inside of the guide cylinder 6 to ensure the stability of the horizontal movement of the moving plate 8.

[0022] The elastic connection mode between the moving plate 8 and the limiting block 15 is as follows: There are no less than two T-shaped columns 17 fixedly connected to one side surface of the limiting block 15. The T-shaped columns 17 slide through the side surface of the moving plate 8. A compression spring 18 is sleeved on the outer surface of the T-shaped columns 17. The compression spring 18 is located between the moving plate 8 and the limiting block 15. At the initial stage of the horizontal movement of the moving plate 8, under the elastic force of the compression spring 18, the moving plate 8 and the limiting block 15 move horizontally synchronously. When the moving plate 8 continues to move horizontally subsequently, the moving plate 8 will squeeze the compression spring 18.

[0023] As Figure 3 , Figure 4 shown, the argon arc welding mechanism includes a guide frame 9 fixedly connected to the lower end of the moving plate 8. A moving seat 10 is slidably inserted into the inside of the guide frame 9. Clamping openings 11 are respectively formed on the front and rear sides of the moving seat 10. The clamping openings 11 are slidably clamped inside the guide frame 9. A welding torch 14 is fixedly inserted at the lower end of the moving seat 10. One end of a threaded rod 12 is rotatably connected to the upper end of one side surface of the moving seat 10. The threaded rod 12 is threadedly penetrated through the side surface of the moving plate 8, and one end of the threaded rod 12 is fixedly connected with a rotating head 13. By rotating the threaded rod 12, the moving seat 10 moves relatively along the inside of the guide frame 9, changing the initial distance between the welding torch 14 and the moving plate 8, ensuring that the distance from the end of the welding torch 14 to the corner of the aluminum single plate is appropriate after the telescopic cylinder 5 extends.

[0024] As Figure 5As shown in the figure, the vertical elastic mechanism includes several convex grooves 27 formed on the front surface of the blocking plate 26. A number of convex blocks 30 are fixedly connected to the rear surface of the pressure strip 31. The convex blocks 30 are slidably inserted into the inner side of the convex grooves 27. A vertical rod 28 is fixedly connected to the inner side of the convex grooves 27. The vertical rod 28 slidably passes through the convex blocks 30. A vertical spring 29 is sleeved on the outer surface of the vertical rod 28. The vertical spring 29 is located on the upper surface of the convex blocks 30. The vertical spring 29 exerts a downward force on the convex blocks 30 to ensure that the pressure strip 31 can abut against the upper edge of the long plate 43 when it moves downward. The vertical rod 28 improves the stability of the sliding of the convex blocks 30 and limits the vertical spring 29 at the same time to prevent the spring from bending and arching during extrusion.

[0025] As Figure 5 , Figure 6 shown in the figure, the horizontal elastic mechanism includes a jack 32 formed at the end of the pressure strip 31. A plug post 35 is slidably inserted into the port of the jack 32. One end of the plug post 35 is fixedly connected to the side surface of a guide roller 36. The other end of the plug post 35 is fixedly connected to a sliding disk 34. A horizontal spring 33 is fixedly connected to one side surface of the sliding disk 34. The horizontal spring 33 is located inside the jack 32. The horizontal spring 33 provides elastic force to ensure that the guide roller 36 can be located on the upper surface of the upper guide plate 20 when the guide roller 36 is not horizontally pushed by the limiting block 15.

[0026] As Figure 2 shown in the figure, the lifting mechanism includes an adjusting cylinder 37 arranged between the processing table 2 and the base 1. The rear end of the lower surface of the processing table 2 is rotatably connected to the base 1. The lower end of the adjusting cylinder 37 is fixedly connected to a lower connecting shaft 41. The two ends of the lower connecting shaft 41 are respectively rotatably connected to lower connecting seats 40. The lower connecting seats 40 are fixedly connected to the inside of the base 1. The telescopic end of the adjusting cylinder 37 is fixedly connected to an upper connecting shaft 39. The two ends of the upper connecting shaft 39 are rotatably connected to upper connecting seats 38. The upper ends of the upper connecting seats 38 are fixedly connected to the lower surface of the processing table 2. The adjusting cylinder 37 is a hydraulic cylinder, which provides stable supporting force. Due to the arrangement of the upper connecting shaft 39 and the lower connecting shaft 41, it is ensured that the two ends of the adjusting cylinder 37 will not be stuck when it expands and contracts.

[0027] As Figure 5 shown in the figure, the driving mechanism includes a rotating shaft 24 rotatably installed at the upper ends between two side plates 3. The upper end of the blocking plate 26 is fixedly connected to the lower surface of the rotating shaft 24. A brake motor 25 is fixedly installed on one side surface of a side plate 3. The output shaft of the brake motor 25 is fixed to one end of the rotating shaft 24. The brake motor 25 is a servo motor with a brake mechanism, which can accurately rotate 360 degrees and brake and position each time it operates.

[0028] The user neatly arranges the aluminum single plates on the upper surface of the processing table 2, and then controls the adjusting cylinder 37 to extend, so that the front end of the processing table 2 rotates upward. At this time, asFigure 7 As shown, under the action of gravity, the aluminum single plate slides backward and downward, and the bottom inclined plate 42 slides along the surface of the processing table 2 until the upper end of the long plate 43 is blocked by the blocking plate 26 and then stops. After that, the welding step is carried out. By extending the telescopic cylinder 5, the moving plate 8 is horizontally displaced, and then the lower end of the welding torch 14 approaches the corner of the aluminum single plate. During this process, first, under the elastic force of the compression spring 18, the limit block 15 horizontally displaces synchronously with the moving plate 8. The limit block 15 pushes the guide roller 36, causing the sliding disk 34 to slide along the inner side of the jack 32, squeezing the horizontal spring 33. After the guide roller 36 moves above the upper guide plate 20, under the elastic force of the vertical spring 29, the pressing strip 31 moves downward and stops after pressing on the upper side of the long plate 43. As the telescopic cylinder 5 continues to extend, the welding torch 14 continues to horizontally displace. At this time, the limit block 15 abuts against the end face of the guide roller 36 and stops. At this time, as Figure 9 shown, the moving plate 8 moves relatively closer to the limit block 15, squeezing the compression spring 18, that is, increasing the pressure on the guide roller 36 by the limit block 15 to ensure that the height position of the pressing strip 31 remains fixed. When the end of the welding torch 14 moves close to the corner of the aluminum single plate, welding is carried out.

[0029] After welding is completed, the telescopic cylinder 5 contracts, causing the welding torch 14 to retract, and the limit block 15 also moves away from the pressing strip 31. Then the brake motor 25 rotates, and the guide roller 36 moves along the upper surface of the curved guide plate 22, and then the pressing strip 31 moves away from the upper side of the long plate 43. Under the action of gravity, the welded aluminum single plate continues to slide backward and downward. At this time, as Figure 10 shown, after the blocking plate 26 rotates one circle, the guide roller 36 moves along the inner side of the major arc plate 21 to the upper surface of the upper guide plate 20 to complete the reset. At this time, as Figure 11 shown, when the aluminum single plate continues to move, the upper part of the short plate 44 moves below the blocking plate 26 without interference, while the long plate 43 of the next aluminum single plate will be blocked by the blocking plate 26 to carry out the welding procedure of another aluminum single plate.

[0030] During the above welding process, multiple sheet metal aluminum single plates can be welded in sequence, which is convenient for operation; during the downward movement of the aluminum single plate, the long plate 43 collides with the blocking plate 26, and at the same time, another aluminum single plate in front will push the front surface of the short plate 44 of the aluminum single plate behind. The front and back pushing actions make the cut at the corner of the folded edge of the aluminum single plate closer, improving the tightness after welding; in the automated sequential welding, the welding points of each aluminum single plate can be kept consistent, improving the welding accuracy; through the pressing action of the pressing strip 31, it helps the aluminum single plate to stay stable, preventing the problem that the long plate 43 still continues to oscillate even after being blocked by the blocking plate 26 and suddenly stops, and assisting in stability to improve the welding accuracy.
