One end of the top outer wall of the base plate 1 is connected to a fixed component via a movable component, and the other end of the top outer wall of the base plate 1 is provided with another fixed component. The two fixed components are arranged opposite to each other.

[0028] The movable component includes a movable groove 2 and a threaded rod 3. The top of the movable groove 2 is located at one end of the top outer wall of the base plate 1. The threaded rod 3 is rotatably connected to the inner wall of the movable groove 2. A movable block 4 is slidably fitted on the inner wall of the movable groove 2. The movable block 4 is threadedly fitted with the threaded rod 3. One end of the threaded rod 3 is connected to a worm gear 13. A worm 12 is driven and meshed on one side of the worm gear 13. One end of the worm 12 is connected to a rotating disk 14 through a connecting shaft. The rotating disk 14 is embedded in the side wall of the base plate 1. A handle 15 is damped and rotatably connected to the side wall of the rotating disk 14, and a groove for storing the handle 15 is provided on the side wall of the rotating disk 14.

[0029] The fixing assembly includes a support rod 5 and a fixing ring 6. The support rod 5 is fixedly connected to the top outer wall of the base plate 1 or the threaded rod 3. The fixing ring 6 is fixedly connected to the top of the support rod 5. A rotating ring 7 coaxial with the fixing ring 6 is provided on one side of the fixing ring 6. A connecting ring 16 is fixed to the side wall of the rotating ring 7. The connecting ring 16 is damped and rotatably connected to the fixing ring 6. A clamping block 9 is fixed to the inner wall of the rotating ring 7. The outer wall of the clamping block 9 near the axis of the rotating ring 7 is V-shaped. A support plate 8 is fixedly connected to the side wall of the support rod 5 through a connecting rod. The support plate 8 slides with the outer wall of the rotating ring 7. A threaded rod 11 opposite to the position of the clamping block 9 is threadedly connected to the outer wall of the rotating ring 7. A clamping plate 10 is rotatably connected to one end of the threaded rod 11. A clamping plate 10 is provided on both sides of the threaded rod 11. A guide rod is provided that slides vertically with the rotating ring 7. The bottom end of the guide rod is fixedly connected to the clamping plate 10. A toothed ring 18 is fixedly connected to the outer wall of the connecting ring 16. A housing 17 is provided on the top outer wall of the fixing ring 6. A limit block 20 slides in the inner wall of the housing 17. The limit block 20 is limited in the fit with the toothed ring 18. A pull rod 19 slides in the top of the housing 17. The bottom end of the pull rod 19 is rotatably connected to the limit block 20. A guide protrusion that slides vertically with the housing 17 is fixed on the side wall of the pull rod 19. There is a gap between the bottom end of the guide protrusion and the top of the limit block 20 that is larger than the thickness of the top of the housing 17. A spring is connected to the top outer wall of the limit block 20. The other end of the spring is connected to the inner wall of the housing 17. A ring-shaped handrail is fixedly connected to one side of the rotating ring 7.

[0030] In use, the metal tube is passed through the fixed ring 6 and the rotating ring 7, and the bottom of the metal tube is supported by the clamping block 9. Then, the threaded rod 11 is rotated to move the clamping plate 10 towards the clamping block 9 to fix the metal tube. After both fixing components have fixed the metal tube, the handle 15 is pulled out of the groove so that the handle 15 is perpendicular to the surface of the rotating disk 14. Then, the handle 15 drives the rotating disk 14 to rotate, which drives the worm gear 12 to rotate. Through the transmission of the worm gear 12 and the worm wheel 13, the threaded rod 3 is driven to rotate, causing the fixing component above the moving block 4 to move closer to the other fixing component along the moving groove 2, so that the two metal tubes are connected. The handle 15 is then... Push the groove back into place, then weld. After part of the welding is completed, pull the lever 19 upward, causing the limiting block 20 to move upward. The spring is compressed and deformed, causing the limiting block 20 to disengage from the toothed ring 18. After the guide protrusion on the side wall of the lever 19 completely leaves the housing 17, rotate the lever 19 to misalign the guide protrusion with its moving groove. The lever 19 is limited by the guide protrusion and the housing 17. Then, grasp the ring handle and rotate the rotating ring 7 to rotate the metal tube and change its posture. Then, reverse the lever 19 so that the spring can drive the limiting block 20 to reset. The limiting block 20 is locked in place with the toothed ring 18, restricting the rotation of the toothed ring 18.

[0031] With the addition of a fixing component, the metal pipes can be adjusted in position without removing the fixing device after some of the metal pipes have been welded, making the operation convenient.

[0032] By embedding the rotating disk 14 into the outer wall of one side of the base plate 1, and connecting the handle 15 to the rotating disk 14 with damping rotation, the handle 15 can be stored after the docking is completed. During welding, the handle 15 will not be accidentally touched, causing the worm gear 12 to rotate and the position of the metal tube to change.

[0033] Example 2

[0034] An auxiliary butt welding device for metal pipe welding is provided in this embodiment, which is based on embodiment 1 and makes the following improvements, such as... Figure 1 As shown, a blocking cover 21 is fixed to the top outer wall of the base plate 1, and a collection box 22 is slidably fitted to the bottom outer wall of the blocking cover 21. The top of the collection box 22 has an opening located below the axis of the fixing ring 6.

[0035] Welding generates waste debris. The waste debris generated during the welding process slides into the collection box 22 through the obstruction of the baffle 21. After the welding is completed, the waste debris removed from the weld falls vertically into the collection box 22. The waste debris generated during welding is collected to prevent the waste debris from scattering randomly, polluting the environment, and being inconvenient to clean.

[0036] By setting up a barrier cover 21 and a collection box 22, the welding waste is collected to prevent the waste from being scattered randomly, polluting the environment, and making cleaning inconvenient.

[0037] Working principle: During use, the metal tube is passed through the fixed ring 6 and the rotating ring 7, and the bottom of the metal tube is supported by the clamping block 9. Then, the threaded rod 11 is rotated, causing the clamping plate 10 to move towards the clamping block 9 to fix the metal tube. After both fixing components have fixed the metal tube, the handle 15 is pulled out of the groove, making the handle 15 perpendicular to the surface of the rotating disk 14. Then, the handle 15 drives the rotating disk 14 to rotate, which in turn drives the worm gear 12 to rotate. Through the transmission of the worm gear 12 and the worm wheel 13, the threaded rod 3 rotates, causing the fixing component above the moving block 4 to move along the moving groove 2 towards the other fixing component, allowing the two metal tubes to connect. The handle 15 is then pushed back into the groove for storage, and welding is performed. After part of the welding is completed, the pulling rod 19 is pulled upwards, causing the limit block 20 to move upwards, compressing the spring. Deformation causes the limiting block 20 to disengage from the toothed ring 18. After the guide protrusion on the side wall of the pulling rod 19 completely leaves the housing 17, the pulling rod 19 is rotated to misalign the guide protrusion with its moving groove. The pulling rod 19 is limited by the guide protrusion and the housing 17. Then, the ring handle is grasped and the rotating ring 7 is rotated to drive the metal tube to rotate and change the posture of the metal tube. Then, the pulling rod 19 is reversed so that the spring can drive the limiting block 20 to reset. The limiting block 20 and the toothed ring 18 are locked together to limit the rotation of the toothed ring 18. Waste chips are generated during welding. The waste chips generated during welding fall into the collection box 22 through the obstruction of the blocking cover 21. After welding is completed, the waste chips removed from the weld seam fall vertically into the collection box 22. The waste chips generated during welding are collected to prevent the waste chips from scattering randomly, polluting the environment, and being inconvenient to clean.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
