[0023] Example 1

[0024] Reference Figures 1 to 4 , an automatic welding device for oil pipelines, comprising a bottom plate 1 with a rectangular opening 18 on the top, a follower block 19 is slidably connected inside the rectangular opening 18, a displacement ring plate 2 is fixedly connected to the top of the follower block 19, an adjusting component for driving the follower block 19 to move is arranged at the bottom of the bottom plate 1, a U-shaped plate 5 is arranged on the outer side of the displacement ring plate 2, a mounting frame 10 is fixedly connected to one side of the U-shaped plate 5, a welding gun 22 is arranged inside the mounting frame 10, a walking component for driving the welding gun 22 to revolve around the displacement ring plate 2 is arranged on one side of the U-shaped plate 5, a stabilizing component is arranged between the inside of the U-shaped plate 5 and the displacement ring plate 2, fixed ring plates 13 are respectively fixedly connected to the two ends of the top of the bottom plate 1, and a positioning component for fixing the oil pipeline is arranged on the inner side of the fixed ring plate 13.

[0025] In the above technical scheme, the positioning assembly is used to fix and clamp the two oil pipelines, so that the oil pipelines with different diameters can be fixed; considering that the position of the connection between the two oil pipelines is not easy to adjust after the two oil pipelines are fixed, the adjustment assembly is used to drive the displacement ring plate 2 to move so that the welding gun 22 is moved to the top of the connection between the two oil pipelines. In this way, moving the position of the welding gun 22 is more convenient and practical than moving the positions of the two oil pipelines; when welding is required, the walking assembly is used to drive the welding gun 22 to revolve around the displacement ring plate 2, and the stabilizing assembly can provide guidance for the U-shaped plate 5 so that it can walk on a predetermined route to prevent deviation, so that the welding work can be automatically completed and the work efficiency can be improved.

[0026] Example 2

[0027] Reference Figure 3 and Figure 4 The travel assembly includes a servo motor 8, which is fixedly mounted on one side of the U-shaped plate 5. The output shaft of the servo motor 8 extends to the inner side of the U-shaped plate 5 and is fixedly connected with a gear 9. A fixed gear ring 4 is provided on one side of the displacement ring plate 2, and the gear 9 meshes with the fixed gear ring 4. By setting the travel assembly, the servo motor 8 is used to drive the gear 9 to rotate, and the gear 9 meshes with the fixed gear ring 4, and the fixed gear ring 4 is fixed, so the gear 9 will rotate while revolving around the displacement ring plate 2, and correspondingly drive the welding gun 22 to revolve.

[0028] Reference Figure 3 The stabilizing component includes an intermediate roller 6, which is rotatably connected between the inner sides of the U-shaped plate 5, and the outer side of the intermediate roller 6 abuts against the inner ring surface of the displacement ring plate 2. The stabilizing component also includes two side circular plates 3, which are respectively fixedly connected to the two sides of the displacement ring plate 2, and the two inner wall surfaces of the U-shaped plate 5 are rotatably connected to two rollers 7, and the outer sides of the rollers 7 abut against the outer ring surfaces of the side circular plates 3. By setting up the stabilizing component, when the walking component drives the U-shaped plate 5 to revolve, the intermediate roller 6 and the inner wall surface of the displacement ring plate 2 have rolling friction, and at the same time, the outer wall of the intermediate roller 6 is concave toward the middle, which will abut against the inner diameter edges on both sides of the displacement ring plate 2, so that the U-shaped plate 5 can be prevented from moving left and right. The roller 7 and the side circular plate 3 also have rolling friction, so that the middle roller 6 and the roller 7 can limit the up and down movement of the U-shaped plate 5. At the same time, two rollers 7 are arranged on the inner wall of one side of the U-shaped plate 5, so that the two rollers 7 and the middle roller 6 form a triangular structure, which enhances the stability of the U-shaped plate 5 during revolution.

[0029] Reference Figure 2The adjustment assembly includes two fixed blocks 20, which are fixedly connected to the two ends of the bottom of the bottom plate 1. A screw rod 21 is rotatably connected between the two fixed blocks 20. The screw rod 21 is threadedly connected to the follower block 19. One end of the screw rod 21 extends to one side of one of the fixed blocks 20 and is provided with a handle. By setting the adjustment assembly, after the oil pipeline is fixed and clamped, the screw rod 21 is rotated to rotate, and the follower block 19 is threadedly connected to the screw rod 21, so the follower block 19 is driven to move, and at the same time, the welding gun 22 is driven to move, so that it moves to the top of the connection between the two oil pipelines.

[0030] Reference Figure 1 and Figure 2 The positioning assembly includes an electric telescopic rod 16, which is fixedly mounted on the outer side of the fixed ring plate 13. One end of the movable rod of the electric telescopic rod 16 extends to the inner side of the fixed ring plate 13 and is fixedly connected to a clamping block 15. Two guide rods 17 are slidably connected to the inner side of the fixed ring plate 13, and one end of the guide rod 17 is fixedly connected to the clamping block 15. The positioning assembly also includes two arc-shaped support plates 14, which are fixedly connected to the inner wall surface of the fixed ring plate 13, and a rubber pad is bonded to one side of the arc-shaped support plates 14. By setting the positioning assembly, the oil pipeline is placed in the middle of the fixed ring plate 13, and the outer wall of the oil pipeline is firstly abutted against the two arc-shaped support plates 14, and then the electric telescopic rod 16 is used to drive the clamping block 15 to move to the side close to the oil pipeline, so that oil pipelines of different diameters can be fixed, and when the clamping block 15 moves, it drives the guide rod 17 to slide inside the fixed ring plate 13, thereby guiding the movement of the clamping block 15 to prevent deviation.

[0031] Reference Figure 4 A threaded rod 11 is threadedly connected to one side of the mounting frame 10, and a squeeze plate 12 is slidably connected inside the mounting frame 10. One side of the squeeze plate 12 abuts against the welding gun 22, and one end of the threaded rod 11 is rotatably connected to the squeeze plate 12. The threaded rod 11 is rotated to drive the squeeze plate 12 to move, so that the squeeze plate 12 is separated from the welding gun 22, so that the extended distance of the welding gun 22 can be adjusted, that is, the distance between the welding gun 22 and the weld of the oil pipeline can be adjusted, so as to be suitable for oil pipelines of different diameters.

[0032] Working principle: When welding the oil pipeline, first place the two oil pipelines in the middle of the fixed ring plate 13, and make the outer wall abut against the two arc-shaped support plates 14, and then use the electric telescopic rod 16 to drive the clamping block 15 to move down, so that the clamping block 15 abuts against the outer wall of the oil pipeline, so as to fix the two oil pipelines; then rotate the rotating plate to drive the screw rod 21 to rotate, thereby driving the follower block 19 to move, and at the same time drive the welding gun 22 to move, and let the welding gun 22 move to the top of the welds of the two oil pipelines; then rotate the threaded rod 11 to drive the extrusion plate 12 to move, so that the extrusion plate 12 is separated from the welding gun 22, and then adjust the distance between the welding gun 22 and the weld. After the adjustment is completed, reverse the threaded rod 11, so as to drive the extrusion plate 12 to abut against the welding gun 22 again, and complete the fixation; finally, use the servo motor 8 to drive the gear 9 to rotate, so that the gear 9 automatically drives the U-shaped plate 5 to revolve around the displacement ring plate 2, so as to drive the welding gun 22 to weld around the connection.

The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
