[0003] In the process of welding titanium alloy tubes, two titanium alloy tubes of the same size need to align the welding ports and make the two independent titanium alloy tubes on the same horizontal line so that the two independent titanium alloy tubes can be welded together more tightly. When welding two independent titanium alloy tubes, it is necessary to maintain the two titanium alloy tubes on the same horizontal axis for a long time. Since the titanium alloy tube is mainly a circular tube structure, it is not convenient to directly determine that the axes of the two independent titanium alloy tubes are on the same horizontal line during the welding process. Therefore, a coaxial positioning welding tool for titanium alloy tubes is proposed to address the above problems. Utility Model Content

[0023] The two ends of the telescopic spring 11 are fixedly connected to the frame 3 and the circular plate 10 respectively. There are two telescopic springs 11 in total, and the telescopic springs 11 are symmetrically arranged on the outside of the frame 3, so as to fix and limit the position of the titanium alloy tube; there are two limit blocks 9 in total, and the side of the limit block 9 close to the center of the support 2 is an arc surface. The limit block 9 slides closely on the outside of the support 2, which can play a relatively stable limiting role on the titanium alloy tube; the pressure block 7 is arranged on the vertical center line of the frame 3, and the side of the pressure block 7 close to the support 2 is an arc surface, which can The two limit blocks 9 on the same vertical plane play a role in three-point positioning of the titanium alloy tube; the belt 13 is in close contact with the clamping ring 15 and the anti-slip rod 16, and the belt 13 is inserted between the "figure eight ring" formed by the clamping ring 15 and the anti-slip rod 16, which can stably restrict the titanium alloy tube on the support block 12; the number of the support block 12 and the frame 3 is the same, and the support block 12 and the frame 3 are both arranged on the same side of the fixed plate 1 with the center of the fixed plate 1 as the symmetrical point, so as to facilitate the determination that the axial centerline positions of the two independent titanium alloy tubes are on the same horizontal straight line.

[0024] Working process: when the positioning welding tool is used to weld the titanium alloy tube, two independent titanium alloy tubes are placed on the support block 12 and the limit block 9 respectively, and then the knob 5 is turned. The knob 5 drives the threaded rod 4 to rotate inside the frame 3, so that the threaded rod 4 can push the pressing block 7 to gradually move closer to the position of the titanium alloy tube until the arc surface of the pressing block 7 fits with the arc surface of the titanium alloy tube, and the knob 5 is continued to be turned. The pressing block 7 exerts pressure on the titanium alloy tube, so that the titanium alloy tube exerts a thrust on the limit block 9, and then the limit block 9 can slide in the direction away from the center of the base 2. At the same time, the limit block 9 pushes the slide rod 8 to slide in the frame 3, and the circular plate 10 fixedly connected to the slide rod 8 can generate a tensile force on the telescopic spring 11 until the titanium alloy tube and the base 2 are tightly together. At this time, the pressing block 7 and the two Under the action of the limit block 9, the position of the titanium alloy tube can be positioned and limited, and then the belt 13 fixedly connected to the outside of the support block 12 is wound around the outside of the titanium alloy tube, so that the belt 13 and the support block 12 completely wrap the titanium alloy tube, and then the belt 13 is inserted into the clamping ring 15, and is staggered and inserted into the outside of the anti-slip rod 16 fixedly connected to the inside of the clamping ring 15. At this time, tightening the belt 13 can stably limit the titanium alloy tube on the support block 12, and finally, the belt 13 is folded and inserted into the limit ring 14, which can effectively prevent the belt 13 from loosening and detaching from the clamping ring 15. Another titanium alloy tube of the same model and size is fixed on the fixed plate 1 in the same way, so that two independent titanium alloy tubes can be placed on the same horizontal axis, so that the user can weld the two titanium alloy tubes together.
