[0032] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0033] To illustrate the concept and purpose of the present invention, the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 13 As shown, an automatic welding machine for welding welding teeth on the end face of a tubular structure comprises:

[0035] The clamping assembly 10 for clamping a tubular structure includes a first rotating disk 11, a first fixed plate 12, and a fixed frame 13. The first rotating disk 11 is rotatably connected to the fixed frame 13, and the first fixed plate 12 is fixedly connected to the first rotating disk 11. The fixed frame 13 is provided with a third guide rail 131, and a slider 132 is slidably provided on the third guide rail 131. A first limit block 133 is fixed to one end of the third guide rail 131, and a second limit block 134 is fixed to the other end. The edge of the first fixed plate 12 is provided with a push block 121 for pushing the slider 132 to slide along the third guide rail 131. The first fixed plate 12 is provided with a first clamping mechanism 14 for clamping parts and a first motor 15 for controlling the clamping or release of the first clamping mechanism 14. The first motor 15 is used to control the first clamping mechanism 14 to clamp or release the tubular structure 71.

[0036] like Figures 1 to 13As shown, the first rotating disk 11 can rotate along the fixing frame 13, and the first clamping mechanism 14 clamps a tubular structure 71. When the fixing frame 13 rotates in one direction, the pushing block 121 rotates together with the first rotating disk 11, and the pushing block 121 contacts one side of the slider 132. The pushing block 121 pushes the slider 132 to slide in one direction along the third guide rail 131; when the slider 132 is pushed to contact the first limit block 133, the first limit block 133 restricts the slider 132 from continuing to slide. At this time, the first limit block 133 prevents the first rotating disk 11 from rotating.

[0037] like Figures 1 to 13 As shown, when the fixed frame 13 rotates in the other direction, the push block 121 rotates along with the first rotating disk 11, disengaging the push block 121 from the slider 132. The first rotating disk 11 continues to rotate, and the push block 121 contacts the other side of the slider 132. The push block 121 pushes the slider 132 to slide along the third guide rail 131 in the other direction. When the slider 132 contacts the second limit block 134, the second limit block 134 prevents the first rotating disk 11 from rotating. Therefore, the first rotating disk 11 can only rotate within a 360-degree range. This facilitates processing of the four sides of the end surface of the tubular structure 71.

[0038] like Figures 1 to 13 As shown, the welding head 20 moves along the X-axis, Y-axis and Z-axis directions to weld the welding teeth 72 to the end surface of the tubular structure 71.

[0039] like Figures 1 to 13As shown, the welding tooth picking mechanism 30 includes a conveying structure 31 for conveying the welding tooth 72, a base 32, a first support frame 33 provided on the upper surface of the base 32, a slide 34 sliding up and down along the first support frame 33, a first cylinder 35, an upper chuck 36, a lower chuck 37, an L-shaped connecting folding plate 38 and a second cylinder 39; the second cylinder 39 is connected to the slide 34, the conveying structure 31 is horizontally arranged and located below the slide 34, the conveying structure 31 is provided with a conveying groove 311 for conveying the welding tooth 72 along the length direction, the lower chuck 37 is fixed to the first cylinder 35 The upper clamp 36 is fixedly connected to the lifting shaft of the first cylinder 35. A clamping space is formed between the lower clamp 37 and the upper clamp 36. The width of the upper clamp 36 and the lower clamp 37 is smaller than the width of the conveying slot 311. The first cylinder 35 controls the up and down movement of the upper clamp 36 and is used to loosen or clamp the welding teeth 72 in the conveying slot 311. The second cylinder 39 is fixedly connected to the slide 34. One end of the connecting folding plate 38 is fixedly connected to the telescopic shaft of the second cylinder 39. The second cylinder 39 is used to control the horizontal movement of the connecting folding plate 38. The other end of the connecting folding plate 38 is fixedly connected to the first cylinder 35. The feed end of the conveying slot 311 is connected to a vibrating plate 60. When the vibrating plate 60 vibrates, it vibrates the welding teeth 72 into the conveying slot 311, and the welding teeth 72 move along the conveying slot 311.

[0040] like Figures 1 to 13 As shown, the welding tooth 72 slides along the conveying slot 311, and baffles 312 are provided on both sides of the front end surface of the conveying slot 311. The baffles 312 are used to prevent the welding tooth 72 from disengaging from the conveying slot 311. When the welding tooth 72 slides along the conveying slot 311, the welding tooth 72 is blocked by the baffles 312. At this time, the second cylinder 39 controls the connecting folding plate 38 to move toward the front end of the conveying slot 311, and then the slide 34 moves downward. When the lower clamp 37 and the upper clamp 36 are aligned with the conveying slot 311, the second cylinder 39 controls the connecting folding plate 38 to move close to the conveying slot 311, and the lower clamp 37 and the upper clamp 36 clamp the welding tooth 72, and the slide 34 drives the lower clamp 37 and the upper clamp 36 to move upward.

[0041] like Figures 1 to 13As shown, the welding tooth feeding mechanism 40 is located between the welding tooth taking mechanism 30 and the clamping assembly 10. The welding tooth feeding mechanism 40 includes a vertically arranged second support frame 41, a second rotating disk 42, a second motor 43 for driving the second rotating disk 42 to rotate, a second fixed plate 47, and a second clamping mechanism 44 for clamping the welding tooth 72 from between the upper chuck 36 and the lower chuck 37 and clamping the welding tooth 72. The second rotating disk 42 is rotatably connected to the second support frame 41, and the second fixed plate 47 is fixedly connected to the second rotating disk 42. The second clamping mechanism 44 is fixedly connected to the second fixed plate 47; the second motor 43 can control the second rotating disk 42 to rotate 180 degrees. When the second clamping mechanism 44 rotates to dock with the lower clamp 37 and the upper clamp 36, the second clamping mechanism 44 clamps the welding teeth 72 between the lower clamp 37 and the upper clamp 36, and the lower clamp 37 and the upper clamp 36 release the welding teeth 72. The second motor 43 controls the second rotating disk 42 to rotate 180 degrees, and the second clamping mechanism 44 rotates 180 degrees with the second rotating disk 42. At this time, the second clamping mechanism 44 rotates to close to the first rotating disk 11.

[0042] like Figures 1 to 13 As shown, the second clamping mechanism 44 includes a left clamp 441, a right clamp 442, a sixth cylinder 443, a fifth cylinder 444 and a third fixed plate 445; the fifth cylinder 444 is fixedly connected to the second fixed plate 47, the telescopic axis of the fifth cylinder 444 is fixedly connected to the third fixed plate 445, the sixth cylinder 443 is fixedly connected to the third fixed plate 445, and the sixth cylinder 443 is used to control the left clamp 441 and the right clamp 442 to clamp or release each other. When the second clamping mechanism 44 rotates to close to the lower chuck 37 and the upper chuck 36, the left chuck 441 and the right chuck 442 are clamped between the lower chuck 37 and the upper chuck 36, the sixth cylinder 443 controls the left chuck 441 and the right chuck 442 to clamp each other and clamp the welding head, the lower chuck 37 and the upper chuck 36 release the welding teeth 72, the second motor 43 controls the second rotating disk 42 to rotate 180 degrees, and the second clamping mechanism 44 rotates 180 degrees with the second rotating disk 42. At this time, the left chuck 441 and the right chuck 442 rotate to close to the first rotating disk 11.

[0043] like Figures 1 to 13 As shown, after the second clamping mechanism 44 clamps the welding teeth 72 between the upper clamp 36 and the lower clamp 37, the second motor 43 drives the second rotating disk 42 to rotate 180 degrees, the welding teeth 72 are connected to the end face of the tubular structure 71, the first rotating disk 11 drives the tubular structure 71 to rotate, and the welding head 20 welds the welding teeth 72 to the end face of the tubular structure 71.

[0044] like Figures 1 to 13As shown, the automatic welding machine also includes a third clamping mechanism 45 for clamping the welding ring 73. The third clamping mechanism 45 is connected to the second fixed plate 47 via a third cylinder 46. A conveyor belt 48 for conveying the welding ring 73 is located directly below the second fixed plate 47. The third cylinder 46 controls the vertical movement of the third clamping mechanism 45. When the conveyor belt 48 conveys the welding ring 73 below the second fixed plate 47, the third cylinder 46 controls the downward movement of the third clamping mechanism 45, clamping the welding ring 73. Then, the second motor 43 controls the second rotating disk 42 to rotate 90 degrees, and the third clamping mechanism 45 rotates 90 degrees with the second rotating disk 42. At this time, the third clamping mechanism 45 rotates close to the first rotating disk 11. The welding ring 73 clamped by the third clamping mechanism 45 is docked with the tubular structure 71, and the welding head 20 welds the welding ring 73 to the end face of the tubular structure 71.

[0046] like Figures 1 to 13 As shown, the first clamping mechanism 14 includes a first clamping portion 141, a second clamping portion 142, a first screw rod 143, a second screw rod 144 and a coupling 145; the first fixed plate 12 is provided with a first guide rail 122 and a second guide rail 123, the first guide rail 122 and the second guide rail 123 are parallel to each other, the first fixed plate 12 is fixed with a first motor 15, the first motor 15 drives the first screw rod 143 to rotate through a pulley, one end of the first clamping portion 141 is slidably connected to the first guide rail 122, and the other end is slidably connected to the second guide rail 123, the second clamping portion 142 One end of the first clamping portion 141 is slidably connected to the first guide rail 122, and the other end is slidably connected to the second guide rail 123.

The second screw rod 144 is connected to the second clamping portion 142 and is used to push the second clamping portion 142 to slide along the first guide rail 122 and the second guide rail 123. The first screw rod 143 and the second screw rod 144 are connected by a coupling 145. The first motor 15 can control the first clamping portion 141 and the second clamping portion 142 to open and close with each other, so that the first clamping portion 141 and the second clamping portion 142 can clamp the tubular structure 71. When the first motor 15 rotates in one direction, the first clamping portion 141 and the second clamping portion 142 are relatively opened; when the first motor 15 rotates in the other direction, the first clamping portion 141 and the second clamping portion 142 are relatively closed.

[0047] like Figures 1 to 13 As shown, the first clamping portion 141 includes a first clamping plate 1411 and a second clamping plate 1412.
