Description

Technical Field

[0001] This utility model relates to the field of pipe welding technology, specifically to a multi-angle welding displacement device for pipe welding. Background Technology

[0002] Pipe fittings are a general term for components in a piping system that serve functions such as connection, control, direction change, flow distribution, sealing, and support. Steel pipe fittings are all pressure-bearing fittings. Based on different manufacturing processes, they are divided into four main categories: welded pipe fittings (both with and without welds), socket weld and threaded pipe fittings, and flanged pipe fittings. There are many types of commonly used pipe fittings. Welded pipe fittings refer to pipe fittings that connect pipelines through welding, mainly including elbows, tees, crosses, reducers, etc., and are usually circular or elliptical in shape. Welded pipe fittings can be further classified according to the connection method into different types such as butt welded, threaded connections, and flanged connections.

[0003] When welding pipe fittings, a clamping mechanism is used to fix the pipe fittings. The original clamping device cannot be adjusted according to the welding angle requirements after fixing the pipe fittings, which means that the overall angle of the device needs to be adjusted manually afterward. The clamping device is heavy, and after a long time of adjustment, it increases the labor force and makes workers tired. When clamping pipe fittings, it is not possible to fix pipe fittings of different diameters, which requires manual adjustment of the fixing range afterward, affecting welding efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a multi-angle welding displacement device for pipe welding. It solves the problem that the original clamping device cannot be adjusted according to the welding angle requirements after fixing the pipe, which leads to the need for manual adjustment of the overall angle of the device. The clamping device is heavy, which increases the labor force and fatigues workers after a long time of adjustment. It is also unable to fix pipes of different diameters when clamping the pipe, which requires manual adjustment of the fixing range and affects the welding efficiency.

[0027] like Figures 1-3 As shown, a multi-angle welding displacement device for pipe welding according to an embodiment of the present invention is illustrated, comprising: a processing table 1, with an installation hole 2 at the front of the upper end of the processing table 1, a sliding groove 3 inside the processing table 1, and a telescopic rod 4 fixedly installed inside the sliding groove 3; a sliding frame 5, fixedly installed at the rear end of the telescopic rod 4, with a first fixing plate 6 fixedly installed at the top of the sliding frame 5, and a moving groove 7 inside the first fixing plate 6, with a first rotator 8 fixedly connected to the rear end of the first fixing plate 6, and a first support plate 9 fixedly installed at the lower end of the first rotator 8, with an electric push rod 10 fixedly connected inside the moving groove 7, and a connecting block 11 fixedly installed at the lower end of the electric push rod 10, and a clamping plate 12 fixedly installed at the lower end of the connecting block 11.

[0028] For example, such as Figure 3 As shown, a rotating gear 13 is fixedly installed inside the mounting hole 2, and a gear ring 14 is meshed inside the rotating gear 13. A rotating plate 15 is fixedly installed on the upper end of the gear ring 14, and a second fixed plate 16 is fixedly connected to the upper end of the rotating plate 15. A second rotator 17 is fixedly installed at the front end of the second fixed plate 16, and a rotating shaft 18 is rotatably connected inside the second rotator 17. A mounting plate 19 is fixedly installed at the front end of the rotating shaft 18, and a second support plate 20 is fixedly installed on the bottom surface of the lower end of the mounting plate 19.

[0029] For example, such as Figure 2 As shown, the sliding groove 3 is symmetrically installed on the left and right sides of the processing table 1 with the interior of the processing table 1 as the center reference. The number of telescopic rods 4 corresponds to the number of sliding grooves 3. The sliding frame 5 is composed of sliding blocks and mounting brackets.

[0030] For example, such as Figure 2 As shown, the lower end of the sliding frame 5 is T-shaped, and the bottom two sides of the sliding frame 5 are connected to the sliding groove 3. The moving groove 7 is symmetrically installed on the upper and lower sides of the first fixed plate 6 with the first fixed plate 6 as the center reference.

[0031] For example, such as Figure 2As shown, the movable groove 7 is symmetrically installed on the left and right sides of the first fixed plate 6 with the first fixed plate 6 as the center reference. The clamping plate 12 is arc-shaped, the upper end of the connecting block 11 is cross-shaped, and the first support plate 9 is L-shaped.

[0032] For example, such as Figure 3 As shown, the second fixing plate 16 has the same structure as the first fixing plate 6, the second rotator 17 has the same structure as the first rotator 8, and the installation height of the second fixing plate 16 and the first fixing plate 6 are on the same straight line.

[0033] In some examples, sliding grooves 3 are opened on both sides of the interior of the processing table 1. The sliding frame 5 is fixed by the telescopic rod 4 inside the sliding groove 3. The first fixed plate 6 follows the sliding frame 5 and slides along the trajectory of the sliding groove 3, moving towards the second fixed plate 16, thereby reducing the distance between the two to accommodate the installation of pipe fittings of different lengths. The opening of the pipe fitting is inserted into the upper end of the arc-shaped clamping plate 12. The clamping plate 12 is connected to the connecting block 11. The connecting block 11 is slidably connected inside the moving groove 7. The connecting block 11 is moved by the electric push rod 10. The electric push rod 10 is started by the PLC controller to drive the connecting block 11 to slide in the moving groove 7. When the clamping plate 12 slides outward along the moving groove 7, the diameter of the pipe fitting clamping increases. When it slides inward, the diameter decreases, thereby adjusting the fixed position according to the diameter of the pipe fitting. After fixing, the pipe fitting is welded. When it is necessary to rotate the pipe fitting, the second rotator 17 is started, and the second fixed plate 16 is rotated through the rotating shaft 18. The fixed plate rotates through the annular mounting bracket at the upper end of the sliding frame 5, thereby driving the pipe fitting to rotate and realizing multi-angle welding.

[0034] For example, such as Figure 4 As shown, it illustrates a multi-angle welding displacement device for pipe welding in another embodiment of the present invention, including a processing table 1 with a housing 21 fixedly connected to the lower end, and brackets 22 fixedly installed on both sides of the housing 21. A gear ring 23 is fixedly installed inside the housing 21, and a coupling gear 24 is meshed inside the gear ring 23. A bonding plate 25 is fixedly installed at the lower end of the coupling gear 24, and a base plate 26 is fixedly installed at the lower end of the bonding plate 25.

[0035] For example, such as Figure 4 As shown, the bracket 22 is symmetrically installed on the front and rear sides of the outer shell 21 with the outer shell 21 as the center reference. The top surface of the bracket 22 is in contact with the bottom surface of the processing table 1. The lower end of the outer shell 21 has an insertion port. The bracket 22 is rotatably connected to the gear ring 23 through the coupling gear 24.

[0036] In some examples, brackets 22 are installed on the front and rear sides of the bottom of the processing table 1. The brackets 22 are connected through the outer shell 21. The outer shell 21 has a second gear ring 23 inside, which meshes with the coupling gear 24. When the processing table 1 is manually rotated, it is supported by the brackets 22 and rotates smoothly by means of the meshing of the second gear ring 23 and the coupling gear 24. When processing small pipes, a rotating plate 15 is fixed at the lower end of the second fixed plate 16. The rotating plate 15 is connected to the first gear ring 14. Through the meshing of the first gear ring 14 and the rotating gear 13, the rotating plate 15 drives the second fixed plate 16 to rotate. The first gear ring 14 is installed inside the mounting hole 2, so that the second fixed plate 16 rotates through the center of the mounting hole 2. The rotation angle range is 90° to 180° to adapt to the multi-angle processing requirements of small pipes.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
