DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] To further understand the features, technical means, and specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the drawings and specific embodiments.

[0026] As Figures 1 to 5As shown in the figure, the present utility model provides a pipeline welding positioning tool for shipbuilding and ship repair, including a welding seat 1. On both sides of the welding seat 1, there are auxiliary alignment components 3 for aligning pipelines. On the welding seat 1, there is a positioning and rotating component 2. The positioning and rotating component 2 includes a positioning ring 26 that can drive the pipeline to rotate along its axis;

[0027] The inner surface of the welding seat 1 is rotatably connected with a bidirectional lead screw 21. One side of the bidirectional lead screw 21 extends to the outside of the welding seat 1 and is fixedly installed with a motor 22. The outer surface of the bidirectional lead screw 21 is rotatably connected with a moving block 23. The upper end of the moving block 23 is fixedly installed with a positioning plate 25. The inner surface of the positioning plate 25 is rotatably connected with a positioning ring 26. One end of the positioning ring 26 extends to the outside of the positioning plate 25 and is fixedly installed with a gear ring 27. One side of the positioning plate 25 is fixedly installed with a connecting block 28. The inner surface of the connecting block 28 is rotatably connected with a rotating rod 29. One end of the rotating rod 29 is fixedly installed with a gear 210. The other end of the rotating rod 29 is fixedly installed with a turntable 211. The outer surface of the positioning ring 26 is fixedly installed with a cylinder 212. The telescopic end of the cylinder 212 is fixedly installed with a clamping block 213. The inner side of the positioning ring 26 is fixedly installed with a first fixing seat 214. The inner surface of the first fixing seat 214 is slidably connected with a limiting plate 215. One side of the limiting plate 215 is fixedly installed with a first spring 216. The other side of the limiting plate 215 is fixedly installed with a connecting plate 217. One end of the connecting plate 217 is fixedly installed with a fixing block 218.

[0028] When welding pipelines for shipbuilding and ship repair is required, first, start the motor 22. The motor 22 drives the bidirectional lead screw 21 to rotate. Then, the bidirectional lead screw 21 drives the moving block 23 to move. The moving block 23 drives the positioning plate 25 to move to a suitable position. Pass the two pipelines to be welded through the positioning rings 26 in the two positioning plates 25 on both sides so that they fit against the fixing block 218. When the fixing block 218 senses the weight, it drives the limiting plate 215 to slide in the first fixing seat 214 through the connecting plate 217 and compresses the first spring 216 to buffer it, preventing excessive placement force from damaging the fixing block 218. Then, start the cylinder 212. The cylinder 212 drives the clamping block 213 to move until it fits against the pipeline to fix the pipeline, facilitating the welding operation by the staff. When the pipeline angle needs to be rotated, rotate the turntable 211. The turntable 211 drives the rotating rod 29 to rotate. Then, the rotating rod 29 drives the gear 210 to rotate. Then, the gear 210 meshes with the gear ring 27 to drive the gear ring 27 to rotate. Then, the gear ring 27 drives the positioning ring 26 to rotate in the positioning plate 25, thus achieving the adjustment of the welding position of the pipeline, reducing the welding difficulty, and improving the welding efficiency.

[0029] As Figure 5 shown,

[0030] One end of the first spring 216 is fixedly connected to one side of the limit plate 215, and the other end of the first spring 216 is fixedly connected to the inner wall of the first fixed seat 214.

[0031] Through the elastic deformation of the first spring 216, the gravity when the pipeline is placed is buffered to prevent the excessive downward pressure from affecting the first fixed seat 214.

[0032] As Figure 1 and Figure 2 shown,

[0033] A bearing seat 24 is arranged at the center of the inner surface of the welding seat 1, and the bidirectional lead screw 21 is rotatably connected to the bearing seat 24.

[0034] The bearing seat 24 provides a supporting force for the bidirectional lead screw 21 to improve the stability of the rotation of the bidirectional lead screw 21.

[0035] As Figure 4 and Figure 5 shown,

[0036] Buffer layers are attached to the outer sides of the clamping block 213 and the fixed block 218, and the buffer layers are made of rubber material.

[0037] Due to the anti-slip performance of the rubber material, the stability of the pipeline placement is improved.

[0038] As Figure 6 and Figure 7 shown,

[0039] The auxiliary alignment component 3 includes auxiliary plates 31 fixedly installed on both sides above the welding seat 1. An auxiliary ring 32 is rotatably connected to the inner surface of the auxiliary plate 31. A second fixed seat 33 is fixedly installed inside the auxiliary ring 32. A connecting rod 34 penetrates through the upper end of the auxiliary ring 32. One end of the connecting rod 34 is fixedly installed with a pull handle 35. The other end of the connecting rod 34 is fixedly installed with a mounting block 36. A second spring 38 is sleeved on the outer surface of the connecting rod 34. An auxiliary block 37 is fixedly installed at the lower end of the mounting block 36.

[0040] During welding, by pulling the pull handle 35, the connecting rod 34 is driven to move by the pull handle 35. Then the connecting rod 34 drives the mounting block 36 to move. The mounting block 36 drives the auxiliary block 37 to move and compresses the second spring 38 on the outer surface of the connecting rod 34. Then the pipeline is passed through the auxiliary ring 32 inside the auxiliary plate 31 and the pipeline is made to fit the second fixed seat 33. At this time, the pull handle 35 is released, and the second spring 38 restores its elastic deformation to drive the auxiliary block 37 to fit the outer surface of the pipeline, so as to achieve auxiliary fixation on the other side of the pipeline, prevent the pipeline from warping and shifting during welding, and ensure the alignment degree of pipeline welding.

[0041] As Figure 7 shown,

[0042] One end of the second spring 38 is fixedly connected to the mounting block 36, and the other end of the second spring 38 is fixedly connected to the inner side of the auxiliary ring 32. There are two groups of connecting rods 34 arranged symmetrically about the center of the auxiliary block 37, and the shape of the auxiliary block 37 is arc-shaped.

[0043] The elastic deformation of the second spring 38 drives the auxiliary block 37 to fix the pipeline, and by arranging two groups of connecting rods 34, the auxiliary block 37 is in the centering position of the pipeline.

[0044] The above embodiments only represent one or several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
