[0024] Please see Figures 1 to 3 This utility model provides a technical solution: an adjustable large pipe welding calibration bracket, including a base 1 and a fixing plate 2. The upper surface of the fixing plate 2 is provided with an installation groove, and a pipe placement rack 3 is fixedly connected to the inner side of the installation groove. The inner side of the base 1 is provided with an adjustment structure for adjusting the height of the pipe placement rack 3.

[0025] like Figure 1 As shown, the adjustment structure includes a dual-output shaft motor 4 fixedly connected to the inner bottom wall of the base 1, transmission rods 5 fixedly connected to the output shafts on the left and right sides of the dual-output shaft motor 4 respectively, a transmission gear 6 fixedly connected to the other end of the transmission rod 5, a driven gear 7 meshing with the bottom of the transmission gear 6, a first threaded rod 8 fixedly connected to the inner side of the center of the driven gear 7, a threaded cylinder 9 threadedly connected to the outer side of the first threaded rod 8, and a connecting plate 10 fixedly connected between the tops of the left and right threaded cylinders 9.

[0026] The upper surface of the connecting plate 10 is provided with auxiliary components for assisting pipe welding.

[0027] It should be noted that the outer wall of the threaded cylinder 9 is square, and the outer side of the threaded cylinder 9 is slidably connected to the limit frame 11, which is fixedly connected to the upper surface of the base 1.

[0028] The left and right sides of the threaded cylinder 9 are fixedly connected with sliders 12, and the inner left and right side walls of the limiting frame 11 are provided with grooves that are compatible with the sliders 12.

[0029] The bottom end of the first threaded rod 8 is rotatably connected to the inner bottom wall of the base 1, and the top end of the first threaded rod 8 moves through the inner top wall of the base 1 and extends to the inner side of the corresponding threaded cylinder 9 and is threadedly connected to the corresponding threaded cylinder 9.

[0030] The auxiliary components include a frame 13 fixedly connected to the upper surface of the connecting plate 10, a drive motor 14 fixedly connected to the front of the frame 13, a second threaded rod 15 fixedly connected to the output shaft of the drive motor 14, a threaded block 16 threadedly connected to the outside of the second threaded rod 15, and a mounting block 17 fixedly connected to the upper surface of the threaded block 16. The fixing plate 2 is fixedly connected to the upper surface of the mounting block 17.

[0031] One end of the second threaded rod 15 passes through the front of the frame 13 and the threaded groove of the threaded block 16 in sequence and is rotatably connected to the inner rear side wall of the frame 13. The upper surface of the frame 13 is provided with a sliding opening that is compatible with the threaded block 16.

[0032] Guide blocks 18 are fixedly connected to the left and right sides of the bottom of the fixed plate 2. Guide rods 19 are slidably connected to the inner side of the guide blocks 18. Both ends of the guide rods 19 are bent downward and fixedly connected to the upper surface of the connecting plate 10. This design provides stable guidance and support for the movement of the fixed plate 2.

[0033] The working principle of the above embodiments is as follows:

[0034] When the height of the pipe placement rack 3 needs to be adjusted, the dual output shaft motor 4 on the inner bottom wall of the base 1 is started. The left and right output shafts of the dual output shaft motor 4 drive the transmission rod 5 to rotate respectively. The other end of the transmission rod 5 is fixedly connected to the transmission gear 6. Therefore, as the transmission rod 5 rotates, the transmission gear 6 also rotates. The bottom of the transmission gear 6 is meshed with the driven gear 7. The rotation of the driven gear 7 will drive the first threaded rod 8 fixedly connected to its inner center to rotate. Since the bottom end of the first threaded rod 8 is rotatably connected to the inner bottom wall of the base 1, and the top end moves through the inner top wall of the base 1 and extends to the inner side of the corresponding threaded cylinder 9, the rotation of the first threaded rod 8 will drive the threaded cylinder 9 to move in the vertical direction.

[0035] The outer wall of the threaded cylinder 9 is square, and a limit frame 11 is slidably connected to the outer side. The limit frame 11 is fixedly connected to the upper surface of the base 1, providing a stable sliding track for the threaded cylinder 9. At the same time, sliders 12 are fixedly connected to both the left and right sides of the threaded cylinder 9. The sliders 12 slide in the grooves opened on the left and right side walls of the limit frame 11, further enhancing the stability of the movement of the threaded cylinder 9.

[0036] Since the connecting plate 10 is fixedly connected between the tops of the threaded cylinders 9 on the left and right sides, as the threaded cylinders 9 move in the vertical direction, the connecting plate 10 and the pipe placement rack 3 on its upper surface will also rise and fall accordingly, thus realizing precise adjustment of the height of the pipe placement rack 3.

[0037] The drive motor 14, which is fixedly connected to the front of the frame 13 on the upper surface of the connecting plate 10, is activated. The output shaft of the drive motor 14 drives the second threaded rod 15 to rotate. The outer side of the second threaded rod 15 is threadedly connected to a threaded block 16. Therefore, as the second threaded rod 15 rotates, the threaded block 16 will move back and forth. The upper surface of the threaded block 16 is fixedly connected to a mounting block 17, and the upper surface of the mounting block 17 is fixedly connected to a fixing plate 2. Therefore, as the threaded block 16 moves back and forth, the fixing plate 2 and the pipe placement bracket 3 on it will also move accordingly, thereby achieving fine adjustment of the pipe position and providing more precise positioning for welding.

The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
