[0035] The purpose of such a design is that, through the welding positioning frame including a cylinder, a fixed positioning mechanism, and a movable positioning mechanism, it is applicable to the welding positioning between two pipes. The movable positioning mechanism is used to adjust the included angle between the two pipes. It solves the problem that the pipes often cannot be accurately assembled. The reason is that during the positioning and combination process, the pipes are displaced, resulting in gaps between the pipes, deviation from the predetermined size, and poor quality after welding.

[0036] In this embodiment, the fixed positioning mechanism includes a tripod 2, a first bottom plate 21, and a first positioning structure;

[0037] One end of the tripod 2 is connected to the first bottom plate 21, and the other end is connected to the cylinder 1;

[0038] The first positioning structure is arranged on the upper surface of the first bottom plate 21 and can place the workpiece to be welded.

[0039] At the same time, a limiting groove is provided on the outer periphery of the cylinder 1. The movable positioning mechanism includes a threaded hole tripod 3, a second bottom plate 31, a limiting bolt 11, and a second positioning structure;

[0040] One end of the threaded hole tripod 3 is connected to the second base plate 31, and the other end is connected to the cylinder 1 through a limit bolt 11 passing through the limit groove.

[0041] The second positioning structure is arranged on the upper surface of the second base plate 31 and can place the workpiece to be welded. Both the tripod 2 and the threaded hole tripod 3 are right-angled tripods, and the connection part with the cylinder 1 is the hypotenuse.

[0042] In actual use, the tripod is connected to the outer periphery of the cylinder by fixed connection methods such as welding. The on-site user adjusts the included angle between the tripod and the threaded hole tripod according to the angle of the welded pipe. The adjustment method is that the threaded hole tripod moves along the limit groove on the outer periphery of the cylinder. After adjusting to the appropriate angle, a detachable fixation is carried out.

[0043] At the same time, in this embodiment, a detachable fixation method is provided. A perforation is arranged on one right-angled side of the threaded hole tripod 3, and the limit bolt 11 can pass through the perforation. The other right-angled side of the threaded hole tripod 3 is connected to the second base plate 31.

[0044] In actual use, after adjusting to the appropriate angle, one end of the limit bolt 11 passes through the limit groove of the cylinder and then inserts through the perforation of the threaded hole tripod to fix the threaded hole tripod.

[0045] In this embodiment, the first positioning structure includes a first threaded top column 22, a first nut 23, and a first positioning hole column 24.

[0046] The first positioning hole column 24 is arranged in the middle of the first base plate 21.

[0048] The first threaded top column 22 passes through the first nut 23 and the first positioning hole column 24. The end of the first threaded top column 22 away from the cylinder 1 is a first internal hexagonal head 25.

[0049] The second positioning structure includes a second threaded top column 32, a second nut 33, and a second positioning hole column 34.

[0050] The second positioning hole column 34 is arranged in the middle of the second base plate 31.

[0052] The second threaded top column 32 passes through the second nut 33 and the second positioning hole column 34. The end of the second threaded top column 32 away from the cylinder 1 is a second internal hexagonal head 35.

[0053] In actual use, the two pipe materials to be welded are respectively placed on the first bottom plate 21 and the second bottom plate 31. Rotate the first hex key wrench 26 to drive the first threaded ejector pin 22 to move forward along the warp line through the first hex head 25, so that the threaded ejector pin 22 cooperates with the cylinder 1 to clamp the first pipe material.

[0054] Rotate the threaded hole tripod 3 to drive the second bottom plate 31, the second threaded ejector pin 32, the second nut 33, the second positioning hole column 34 and the second pipe material to rotate. When the second pipe material is joined with the first pipe material, rotate the second hex key wrench 36 to drive the second threaded ejector pin 32 to move forward along the warp line through the second hex head 35, so that the second threaded ejector pin 32 cooperates with the cylinder 1 to clamp the second pipe material. When the second pipe material and the first pipe material reach the best matching state, fasten again, and then the welding operation can be started.
