Detailed implementation manners

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0017] Refer to Figures 1-4, the utility model provides a fence welding device, which includes a bottom plate 1. On both sides of the top surface of the bottom plate 1, two support plates 2 are fixedly connected. The two support plates 2 are symmetrically arranged. A flipping frame 3 is rotatably connected between the two support plates 2. A fence to be welded 4 is arranged on the flipping frame 3. Two limiting components are arranged on the flipping frame 3, and the two limiting components are respectively arranged corresponding to the two sides of the fence to be welded 4. A lifting component for controlling the vertical movement of the flipping frame 3 is installed on the support plate 2; on one side of the bottom plate 1, there is a support seat 5, and a robotic arm 6 is installed on the support seat 5. A welding torch 7 is clamped at the end of the robotic arm 6. By arranging the flipping frame 3 between the two support plates 2 and using the two limiting components on the flipping frame 3 to limit the two sides of the fence to be welded 4 respectively, it is stabilized on the flipping frame 3 and is not likely to shake during the welding process, ensuring the welding effect. At the same time, the flipping frame 3 can be rotated as needed, facilitating the welding torch 7 to fully weld the fence incision, ensuring the welding strength and eliminating the need for manual flipping, improving work efficiency.

[0018] In a specific embodiment, the flipping frame 3 includes two parallel mounting plates 301. The two mounting plates 301 are arranged corresponding to the two support plates 2 one by one. A connecting column 302 is arranged between the corresponding mounting plate 301 and the support plate 2. One end of the connecting column 302 is fixedly connected to the mounting plate 301, and the other end of the connecting column 302 is rotatably connected to the support plate 2. Two parallel connecting plates 303 are fixedly connected between the two mounting plates 301. The two limiting components are respectively located on different connecting plates 303. A flipping motor 8 is arranged on any one of the support plates 2, and the output shaft of the flipping motor 8 is fixedly connected to the connecting column 302. By driving the connecting column 302 to rotate through the flipping motor 8, the mounting plate 301 and the connecting plate 303 are driven to rotate, enabling angle adjustment as needed and facilitating full welding. Since the fence to be welded 4 is directly placed on the connecting plate 303 when placed, by installing the limiting components on the connecting plate 303, the fence to be welded 4 can be clamped and limited, preventing it from shifting during the welding process and ensuring the welding effect.

[0019] In a specific embodiment, each limiting component includes two limiting blocks 9 located on the same connecting plate 303. The cross-section of the limiting block 9 is L-shaped. The limiting blocks 9 are respectively in sliding fit with the top surface and one side surface of the connecting plate 303. A receiving cavity 10 is formed in the connecting plate 303. A bidirectional threaded rod 11 is rotatably connected in the receiving cavity 10. The thread directions on both sides of the bidirectional threaded rod 11 are opposite. Two sliders 12 are slidably connected in the receiving cavity 10. The cross-section of the receiving cavity 10 is square, and the slider 12 is adapted to the receiving cavity 10. The bidirectional threaded rod 11 passes through both sliders 12 and is threadedly connected to the sliders 12. The two sliders 12 are respectively located on the two sides with opposite thread directions of the bidirectional threaded rod 11. The two sliders 12 are arranged in one-to-one correspondence with the two limiting blocks 9. A connecting rod 13 is fixedly connected between the corresponding slider 12 and the limiting block 9. An opening groove 14 for the movement of the connecting rod 13 is formed in the side wall of the receiving cavity 10. The connecting rod 13 is located in the opening groove 14 and is in sliding connection with the inner wall of the opening groove 14; Two driving motors 15 are fixedly connected to any one mounting plate 301 corresponding to the two bidirectional threaded rods 11. The output shaft of the driving motor 15 sequentially passes through the mounting plate 301 and the connecting plate 303 and is fixedly connected to the bidirectional threaded rod 11. By driving the bidirectional threaded rod 11 to rotate through the driving motor 15, since the thread directions on both sides of the bidirectional threaded rod 11 are opposite, the two sliders 12 are driven to move towards each other or away from each other during the rotation of the bidirectional threaded rod 11. Furthermore, the two limiting blocks 9 are driven to move towards each other or away from each other through the connecting rod 13. When moving towards each other, the long crossbars in the to-be-welded fence 4 can be clamped and limited, so that the to-be-welded fence 4 will not shift during the welding process, and it can cooperate with the flipping frame 3, facilitating the welding gun 7 to fully weld the to-be-welded cut, ensuring the welding effect.

[0020] In a specific embodiment, the lifting component includes a strip-shaped groove 16 formed in the support plate 2. A lifting block 17 is slidably connected in the strip-shaped groove 16. The two connecting columns 302 are arranged in correspondence with the two lifting blocks 17. The corresponding connecting column 302 is rotatably connected to the lifting block 17. A cross plate 18 is slidably connected to any one support plate 2. The flipping motor 8 is fixedly installed on the cross plate 18. The output shaft of the flipping motor 8 passes through the lifting block 17 and is fixedly connected to the connecting column 302; A telescopic electric cylinder 19 is fixedly connected to the top of the support plate 2. The telescopic end of the telescopic electric cylinder 19 passes through the top wall of the strip-shaped groove 16 and is located in the strip-shaped groove 16. The telescopic end of the telescopic electric cylinder 19 is fixedly connected to the corresponding lifting block 17. The telescopic electric cylinder 19 drives the lifting block 17 to move up and down, thereby driving the connecting column 302 to move up and down, and then driving the entire flipping frame 3 to move up and down, so as to adjust the horizontal height of the flipping frame 3 as needed.

[0021] In a specific embodiment, the robotic arm 6, the welding gun 7, the flipping motor 8, the driving motor 15, and the telescopic electric cylinder 19 are all controlled by a numerical control unit. This technology is an existing technology and will not be elaborated here.

[0022] Working process of the utility model: During use, the to-be-welded fence 4 that has been simply connected by spot welding is conveyed onto the bottom plate 1. The entire flipping frame 3 is driven downward by the telescopic electric cylinder 19. Then, the driving motor 15 drives the bidirectional threaded rod 11 to rotate, thereby driving the two limiting blocks 9 to clamp and limit the two longer railings of the to-be-welded fence 4 in the horizontal direction. Then, the telescopic electric cylinder 19 drives the flipping frame 3 upward. Then, the flipping motor 8 drives the connecting column 302 to rotate, thereby driving the entire flipping frame 3 to adjust the angle, facilitating the robotic arm 6 to drive the welding torch 7 to perform all-round welding on the to-be-welded cut of the fence and ensuring the welding effect. After welding is completed, the flipping motor 8 will keep the flipping frame 3 horizontal. Then, the telescopic electric cylinder 19 makes the flipping frame 3 move downward. Then, through the adjustment of the driving motor 15, the limiting blocks 9 no longer clamp the to-be-welded fence 4, and the welded fence falls onto the bottom plate 1, facilitating transportation and collection.
