Description

Technical Field

[0001] This invention relates to the field of welding processing technology, and in particular to an auxiliary device for welding pipe fittings. Background Technology

[0002] Existing pipe welding methods require manual fixing during welding and manual operation during the welding process.

[0003] Chinese Patent Publication No. CN118081280B discloses a mechanical pipe welding auxiliary positioning device, relating to the field of auxiliary positioning technology. It includes a worktable with a working frame mounted on its top, the work frame and worktable forming a rectangular structure. A welding mechanism is also included, comprising an electric push rod and a mounting block. The electric push rod is mounted in the middle of the top of the working frame, and the mounting block is mounted on the bottom of the electric push rod. When welding two pipe fittings, the opposite ends of the two pipe fittings are extended into the inner sides of the working frame and fixed by a moving and fixing mechanism. After fixing, the pipe fittings are moved by the moving mechanism. Once the movement is complete, the welding mechanism is activated for welding. The welding mechanism triggers a reinforcement mechanism, increasing the stability of the welding rod during use. Since pipe welding is usually done in batches, workers need to sort the pipe fittings from a pile and place them on the processing table, a time-consuming and labor-intensive method that affects work efficiency.

[0004] In view of this, the present invention proposes an auxiliary device for pipe welding to solve the problems existing in the prior art. Summary of the Invention

[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0025] Reference Figures 1-2An auxiliary device for pipe welding includes a storage box 6 with an outlet 12 at its lower end. The bottom end of the outlet 12 is connected to a material distribution cylinder 5. A material distribution column 17 is rotatably connected inside the material distribution cylinder 5, and a rotating mechanism is provided at one end of the material distribution column 17. A rectangular cavity 11 is provided inside the material distribution column 17, and multiple material distribution slots 15 are evenly spaced on the outer wall of the material distribution column 17. Two rotating cylinders 10 are rotatably connected at the connection between each material distribution slot 15 and the rectangular cavity 11. Each rotating cylinder 10 is equipped with a telescopic mechanism. Each of the rectangular cavities 11 is equipped with an embedded plate 9, one end of which has a triangular cross-section. A driving mechanism is installed on the inner walls of each cavity 11 to drive the corresponding rotating cylinder 10 to rotate. A separating mechanism is installed on the outlet 12. A discharge port is opened at the bottom of the distribution column 17, allowing the pipe fittings to be welded to be placed into the storage box 6. The separating mechanism in the outlet 12 prevents the pipe fittings from falling into the distribution cylinder 5. A gap exists between the pipe fitting in the outlet 12 and the inner wall of the outlet 12, allowing the embedded plate 9 to pass through. The rotation... The mechanism enables the material distribution column 17 in the material distribution cylinder 5 to rotate. When one of the material distribution grooves 15 in the material distribution column 17 is aligned with the outlet 12, the telescopic mechanism on the two rotating cylinders 10 in the material distribution groove 15 is activated, causing the embedded plate 9 to move upward until the embedded plate 9 exceeds the pipe on the separating mechanism. Then, the drive mechanism is activated, causing the rotating cylinder 10 to rotate, thereby embedding the embedded plate 9 between the two pipes, thus separating the pipe below the embedded plate 9 from the pipe above it. Then, the separating mechanism is opened, and the pipe between the separating mechanism and the embedded plate 9 falls into the material distribution groove 15. At the same time, under the action of the telescopic mechanism, the embedded plate 9 moves downward into the material distribution groove 15. Then, the rotating mechanism is activated, so that the next material distribution groove 15 is aligned with the outlet 12. Then, the above operation is repeated. When the material distribution groove 15 with the pipe is aligned with the outlet, the drive mechanism is activated again, so that the embedded plate 9 is reset and parallel to the material distribution groove 15. Thus, the pipe in the material distribution groove 15 can fall out through the outlet, completing the sorting work and facilitating subsequent welding processing.

[0026] Reference Figure 1 As a further embodiment of the present invention, the rotating mechanism includes a first pulley 3, a transmission belt 7, a second pulley 8, and a drive motor 4. The first pulley 3 is fixedly connected to the output shaft end of the drive motor 4, the drive motor 4 is fixedly connected to the outer wall of the distributing cylinder 5, the second pulley 8 is fixedly connected to one end of the distributing column 17, the transmission belt 7 is sleeved on the outer walls of the first pulley 3 and the second pulley 8, and the drive motor 4 can rotate the distributing column 17 through the cooperation of the first pulley 3, the transmission belt 7, and the second pulley 8.

[0027] Reference Figure 6As a further embodiment of the present invention, the telescopic mechanism includes a rectangular plate 28, which is slidably connected to one side of the rotating cylinder 10, and an electromagnet 31 is provided on the inner wall of the other side of the rotating cylinder 10. An embedded plate 9 is fixedly connected to one end of the rectangular plate 28, and a magnetic plate 29 is fixedly connected to the other end of the rectangular plate 28. A connecting spring 30 is fixedly connected between the magnetic plate 29 and the electromagnet 31. When current is input into the electromagnet 31, the magnetic force generated by the electromagnet 31 after being energized repels the magnetic plate 29, thereby increasing the length of the rectangular plate 28 extending out of the rotating cylinder 10 through the magnetic plate 29.

[0028] Reference Figure 2 and Figure 5 As a further embodiment of the present invention, the driving mechanism includes two racks 26, which are slidably connected to the inner wall of the rectangular cavity 11, and a connecting post 27 is fixedly connected between the two racks 26. A gear 16 is meshed on one side of each rack 26, and the gear 16 is fixedly connected to the outer wall of the corresponding rotating cylinder 10. An electric push rod 25 is provided on one side of the outer wall of one of the racks 26. The electric push rod 25 pushes the rack 26 to move. Because the rack 26 meshes with the gear 16 on the rotating cylinder 10, the embedded plate 9 can be rotated by the rotating cylinder 10.

[0029] Reference Figure 3 As a further embodiment of the present invention, the separating mechanism includes a baffle 20, which is slidably connected to the outlet 12. Two electric push rods 14 are embedded in the outer wall of the outlet 12. The telescopic ends of the electric push rods 14 are directly fixedly connected to the outer wall of the baffle 20 with a connecting plate 21. The baffle 20 can prevent the pipe from falling into the distributing cylinder 5. There is a gap between the baffle 20 and the inner wall of the outlet 12. This gap allows the telescopic mechanism to carry the embedded plate 9 through. The electric push rods 14 can move the baffle 20, thereby allowing the pipe to fall downwards.

[0030] Reference Figure 1 As a further embodiment of the present invention, a vertical plate 1 is fixedly connected to one side of the bottom of the discharge port, and a drop plate 2 is fixedly connected to the outer wall of the vertical plate 1. The pipe fittings falling through the discharge port can fall onto the drop plate 2. Under the action of the drop plate 2, the pipe fittings can fall onto the workbench, thereby facilitating welding.

[0031] Working principle: The pipe fittings to be welded are placed into the storage box 6. The separating mechanism in the outlet 12 prevents the pipe fittings from falling into the distributing cylinder 5. There is a gap between the pipe fittings in the outlet 12 and the inner wall of the outlet 12, which allows the embedding plate 9 to pass through. The distributing column 17 in the distributing cylinder 5 can be rotated by the rotating mechanism. When one of the distributing grooves 15 in the distributing column 17 is aligned with the outlet 12, the telescopic mechanism on the two rotating cylinders 10 in the distributing groove 15 is activated, causing the embedding plate 9 to move upward until the embedding plate 9 passes the pipe fittings on the separating mechanism. Then the drive mechanism is activated, causing the rotating cylinder 10 to rotate, thereby embedding the embedding plate 9. The pipe is separated from the pipe below the embedded plate 9 by the pipe above it. The separating mechanism then opens, allowing the pipe between the separating mechanism and the embedded plate 9 to fall into the sorting trough 15. Simultaneously, the telescopic mechanism moves the embedded plate 9 downward into the sorting trough 15. Then, the rotating mechanism starts, aligning the next sorting trough 15 with the outlet 12. The above operation is repeated. When the sorting trough 15 with the pipe is aligned with the outlet, the drive mechanism starts again, resetting the embedded plate 9 so that it is parallel to the sorting trough 15. Thus, the pipe in the sorting trough 15 can fall out through the outlet, completing the sorting process and facilitating subsequent welding.

[0032] Reference Figure 3 As a further embodiment of the present invention, an inclined plate 19 is hinged to the inner wall above one side of the outlet 12, and a diameter adjustment plate 18 is hinged to the bottom end of the inclined plate 19. Two electric push rods 13 are provided on one side of the diameter adjustment plate 18, and the telescopic ends of the two electric push rods 13 are in contact with the outer wall of the diameter adjustment plate 18. The distance between the diameter adjustment plate 18 and the outlet 12 can be adjusted by the electric push rods 13, so that the distance between the diameter adjustment plate 18 and the outlet 12 is 1.2 to 1.4 times the diameter of the pipe to be processed, ensuring that the telescopic mechanism will not be obstructed when the embedded plate 9 moves upward. Thus, by adjusting the distance between the diameter adjustment plate 18 and the outlet 12, it is possible to adapt to the welding and processing of pipes with different diameters.

[0033] Reference Figure 3 As a further embodiment of the present invention, the diameter adjustment plate 18 is provided with a receiving cavity 24, and a telescopic plate 22 is slidably connected to the bottom of the receiving cavity 24. A connecting spring 23 is fixedly connected between the telescopic plate 22 and the inner wall of the receiving cavity 24. The bottom end of the telescopic plate 22 is semi-circular. Under the action of the connecting spring 23, the bottom end of the telescopic plate 22 can contact the top outer wall of the baffle 20, so that the telescopic plate 22 can seal the gap between the diameter adjustment plate 18 and the baffle 20, preventing the pipe from getting stuck in the gap. Furthermore, if the pipe falls when the baffle 20 moves, the bottom end of the telescopic plate 22 will not detach from the surface of the baffle 20.

[0034] Working principle: The distance between the diameter adjustment plate 18 and the outlet 12 can be adjusted by the electric push rod 13, so that the distance between the diameter adjustment plate 18 and the outlet 12 is 1.2 to 1.4 times the diameter of the pipe to be processed. This ensures that the telescopic mechanism will not be obstructed when the embedded plate 9 moves upward. By adjusting the distance between the diameter adjustment plate 18 and the outlet 12, it can be used to weld pipes of different diameters. Under the action of the connecting spring 23, the bottom end of the telescopic plate 22 can contact the top outer wall of the baffle 20. Thus, the telescopic plate 22 can seal the gap between the diameter adjustment plate 18 and the baffle 20, preventing the pipe from getting stuck in the gap. Furthermore, if the pipe falls when the baffle 20 moves, the bottom end of the telescopic plate 22 will not detach from the surface of the baffle 20.
