[0002] When welding special-shaped pipes, in order to ensure welding quality and efficiency, special tooling devices are needed to fix and position the pipes so that welders can easily perform welding operations. Special-shaped pipes refer to pipes with unconventional shapes or curves, which usually require special tooling devices to maintain their shape and position for welding.

[0003] When welding special-shaped pipes, if there is no suitable tooling, it is difficult for welders to fix the pipes in the correct position, and it may cause uneven weld joints or substandard welding quality. Therefore, the use of special tooling can greatly improve welding quality and efficiency, while also ensuring the safety of welders.

[0004] At present, the welding tooling for special-shaped pipes is usually composed of various clamps, brackets, positioners, etc., and is designed and manufactured according to the specific shape and size of the pipe. These tooling devices can help welders quickly and accurately fix and position the pipes, thereby ensuring the smooth progress of welding operations, but they cannot fix various types of special-shaped pipes and require additional customization, which increases costs. In addition, fixing special-shaped pipes requires multiple sets of clamps, but multiple clamps cannot be adjusted at the same time. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 2The utility model provides an embodiment: comprising a workbench 1, the inner wall of the workbench 1 is slidably connected to a base 2, a clamping device is installed on the base 2, which slides along the inner wall of the workbench 1 and can be adjusted and fixed according to the special-shaped tube, the inner wall of the workbench 1 is elastically connected to a frame 19 through a reset spring a18, one end of the reset spring a18 is fixedly connected to the left side wall of the frame 19, and the other end of the reset spring a18 is fixedly connected to the inner wall of the workbench 1, the frame 19 can squeeze the reset spring a18 to slide to the left, and at the same time, the elastic force generated by the deformation of the reset spring a18 gives the frame 19 a reverse thrust to reset it, and the side wall of the frame 19 is connected to the The inner wall of the workbench 1 is slidably connected, and a pull rod 17 is fixedly connected to the left side wall of the frame 19. The outer wall of the pull rod 17 penetrates the inner wall of the workbench 1 and is slidably connected. Pulling the pull rod 17 outward can drive the frame 19 to move to the left. Several rows of limit blocks 20 are arranged on the inner wall of the frame 19, and a slot 3 is opened on the inner wall of the base 2. The outer wall of the limit block 20 is plugged into the inner wall of the slot 3. Under normal circumstances, the limit block 20 is inserted into the slot 3 to fix the position of the base 2. When it needs to be moved, the pull rod 17 must be pulled until the limit block 20 is pulled out of the slot 3. At this time, the position of the base 2 can be adjusted. The adjustment method is simple, and all clamping devices can be released at one time.

[0031] Reference Figure 1 and Figure 3The inner wall of the base 2 is rotatably connected to a rotating rod 4, and the inner wall of the rotating rod 4 is elastically connected to a buckle assembly through a return spring b5. The buckle assembly includes a block 6, one end of the return spring b5 is fixedly connected to the inner end of the block 6, and the other end of the return spring b5 is fixedly connected to the inner wall of the rotating rod 4. Pressing the block 6 inward can squeeze the return spring b5 to move into the groove of the rotating rod 4. At the same time, the elastic force generated by the deformation of the return spring b5 gives the block 6 an outward thrust due to the deformation, prompting it to reset. A plurality of groups of slots 7 are provided on the inner wall of the base 2, and the outer wall of the block 6 is engaged with the inner wall of the slot 7. The block 6 is pressed inward until the engagement with the slot 7 is released. At this time, the rotating rod 4 can be rotated to change the angle of the clamping device. The inner wall of the rotating rod 4 is slidably connected to a skeleton 12, and the inner wall of the rotating rod 4 is rotatably connected to a threaded rod a9, and a knob a8 is fixedly connected to the end of the threaded rod a9. The outer wall of the threaded rod a9 is threadedly connected to two groups of threaded sleeves 10 with reverse threads. The button a8 rotates the threaded rod a9, so that the two groups of threaded sleeves 10 with reverse threads are brought closer to or separated from each other. The outer wall of the threaded sleeve 10 is hinged with a bracket 11, and the end of the bracket 11 is hinged with the bottom end of the skeleton 12. The threaded sleeves 10 are brought closer to or separated from each other, so that the angle of the bracket 11 changes, thereby driving the skeleton 12 to rise or fall along the inner wall of the rotating rod 4, and the overall height of the adjustment device is adjusted, and the adjustment is more precise. The inner wall of the skeleton 12 is fixedly connected with a guide rod 15, and the outer wall of the guide rod 15 is slidably connected with two groups of clamping blocks 16.

The inner walls of the two groups of clamping blocks 16 are threadedly connected with threaded rods b14, and the end of the threaded rod b14 is fixedly connected with a knob b13. The bottom end of the clamping block 16 is slidably connected to the inner wall of the skeleton 12. Turning the knob b13 rotates the threaded rod b14. Reverse threads are set inside the two groups of clamping blocks 16, and they move closer to each other as the threaded rod b14 rotates to fix the special-shaped tube.

[0032] Working principle: adjust the horizontal position of the clamping device according to the shape of the special-shaped tube, pull the pull rod 17 outward until the limit block 20 is disengaged from the slot 3, and then the base 2 can be slid along the inner wall groove of the workbench 1 to adjust the horizontal position of the clamping device. Multiple groups of clamping devices can be fixed at the same time, and then press the block 6 inward to disengage it from the slot 7, and then rotate the rotating rod 4 to adjust the overall angle of the device. After that, turn the knob a8 to make the threaded rod a9 rotate together until the two groups of threaded sleeves 10 are close to or separated from each other, driving the angle of the bracket 11 to change, and adjusting the overall height of the device. Finally, place the special-shaped tube between the adjusted device clamps 16, and turn the knob b13 to make the two groups of clamps 16 close to each other to fix the special-shaped tube.
