[0020] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: An auxiliary positioning tool for automobile pipeline molding, see Figures 1 to 5 , including a bottom plate 1, both sides of the top of the bottom plate 1 are fixedly connected to the vertical plates 11, a support tube 2 is installed on one side of the vertical plate 11, and rectangular holes 21 are opened on the upper and lower sides of the support tube 2, the inner cavity of the support tube 2 is rotatably connected to the screw rod 22, and a moving block 24 is slidably connected in the support tube 2, and the moving block 24 is threadedly sleeved on the outer side of the screw rod 22. One side of the inner cavity of the two rectangular holes 21 is rotatably connected to the first connecting plate 29 through a rotating shaft, and a first connecting block 25 is installed on both sides of the upper and lower ends of the moving block 24. The two first connecting blocks 25 on the same side are rotatably connected to the second connecting plate 26 through a rotating shaft, and the other ends of the first connecting plate 29 and the second connecting plate 26 on the same side are both rotatably connected by a rotating shaft. The shaft is rotatably connected to a second connecting block 27, and a support plate 28 is fixedly connected between the two second connecting blocks 27 on the same side. The surface of the support plate 28 is set in an arc shape. During operation, the automobile pipeline to be welded and formed is sleeved on the outside of the support tube 2, and then the connection between the two pipelines is aligned with the support plate 28. Then, the screw rod 22 is turned to rotate the adjustment moving block 24 to move in the support tube 2, thereby cooperating with the first connecting plate 29 and the second connecting plate 26 to squeeze the support plate 28 at the connection between the two automobile pipelines, so that the inner side of the pipeline at the welding point can be supported, thereby avoiding the occurrence of depressions at the pipeline welding point during welding, affecting the quality of pipeline welding, and further improving the quality of pipeline welding forming.

[0022] For details, see Figure 1The outer side of the support tube 2 is provided with an external thread 3, and the outer side of the support tube 2 is threadedly sleeved with a first tapered tube 31. The vertical plate 11 at the other end is penetrated by a screw 4, and the screw 4 is threadedly connected to the vertical plate 11. The screw 4 is fixedly connected to the second tapered tube 42 at one end close to the support tube 2. The center of the screw 4 and the support tube 2 are on the same horizontal line. The first tapered tube 31 and the second tapered tube 42 have the same size and are on the same horizontal plane. When the automobile pipeline to be welded is sleeved on the outer side of the support tube 2, the first tapered tube 31 is inserted into one end of one of the welded pipelines by rotating the first tapered tube 31, and then the screw 4 is turned to drive the second tapered tube 42 to be inserted into one end of the other welded pipeline, so that one side of the two welded pipelines can be limited, thereby improving the stability of the two pipelines during welding, and further improving the quality of pipeline welding.

[0023] For further information, see Figure 1 The end of the screw 4 away from the second conical cylinder 42 is fixedly connected to the first hand wheel 41, and the end of the screw rod 22 is fixedly connected to the second hand wheel 23. The first hand wheel 41 and the second hand wheel 23 are convenient for people to hold, and then convenient for people to manually twist the screw 4 and the screw rod 22 to rotate and adjust the position of the second conical cylinder 42 and the first conical cylinder 31.

[0024] It is worth noting that, see Figure 1 and Figure 2 A first protective pad 32 and a second protective pad 43 are respectively installed on the outside of the first conical cylinder 31 and the second conical cylinder 42, which not only prevents the first conical cylinder 31 and the second conical cylinder 42 from directly contacting the pipeline and causing wear, but also increases the friction between the first conical cylinder 31 and the second conical cylinder 42 and the inner wall of the pipeline, thereby improving the stability of the first conical cylinder 31 and the second conical cylinder 42 in fixing the pipeline.

[0025] It is worth noting that see Figure 5 Limiting grooves 5 are provided on both sides of the inner cavity of the support tube 2, and limiting blocks 51 are slidably connected in the two limiting grooves 5. Limiting rods 52 are fixedly connected between the two limiting blocks 51 and both sides of the moving block 24. The limiting blocks 51 are guided to move in the limiting grooves 5, and the limiting rods 52 are used to guide the moving block 24, thereby improving the stability of the movement of the moving block 24.
