[0002] Pipe butt welding is a commonly used metal connection technology, widely used in industry and construction. Pipe butt welding is a process of heating the interface of two pipes to a molten state, then fusing them together, and forming a solid connection after cooling. When welding, the pipes need to be aligned. The size of the butt weld varies with the thickness of the pipes. The alignment fixture currently used requires workers to move the pipes themselves to adjust the size of the welds, which is laborious and time-consuming. In addition, the existing fixtures only use bolts to fix the pipes, which can easily damage the paint film on the outside of the pipes and cause damage to the pipes. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0017] like Figure 1 As shown, the pipe butt welding fixing device includes a base 1, a fixing mechanism, a pressure plate 3, a screw 6, and a support 7. There are two fixing mechanisms, which are symmetrically installed on the base 1. The base 1 is provided with a full-length groove with an opening facing upward, and a pressure plate 3 is connected to each of the top sides of the groove by bolts. The bottoms of the two fixing mechanisms are slidably connected in the slideway formed by the two pressure plates 3 and the groove. A support 7 is fixedly connected to each of the two ends of the base 1. One end of the screw 6 is rotatably connected to the support 7, and the other end is screwed to the fixing mechanism. The support 7 is provided with a U-shaped groove with an opening facing upward, and one end of the screw is rotatably clamped in the U-shaped groove, and the other end is screwed to the fixing mechanism. Rotating the screw 6 drives the fixing mechanism to move left and right.
[0018] The first embodiment of the fixing mechanism is as follows Figure 2 As shown, the fixing mechanism includes a slider 2 and two fixing rings 4. The slider 2 is an inverted T-shaped structure. The two fixing rings 4 are fixedly connected to the top of the slider 2 at intervals. The pipe 5 is clamped on the fixing ring 4, and the lead screw 6 is screwed on the slider 2. The fixing ring 4 is a whole circular ring structure. A plurality of connecting blocks 43 are fixedly connected to the circular ring structure along the circumference and radial direction. Each connecting block 43 is provided with a threaded through hole. The bolt 44 passes through and is screwed to the threaded through hole.
