[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a steel pipe flange assembly positioning device, including a support mechanism 1, a flange body 2 and a steel pipe body 3. The support mechanism 1 includes a lower base plate 11 as a base. A plurality of support columns 12 for support are fixedly connected in a ring array on the upper end face of the lower base plate 11. An upper top plate 13 is rotatably sleeved on the upper end face of the plurality of support columns 12. A positioning mechanism 4 for centering the flange body 2 and the steel pipe body 3 is provided on the lower end face of the upper top plate 13.

[0021] By adopting the above technical solution and through the precise design of the positioning mechanism 4, the coaxial positioning of the flange body 2 and the steel pipe body 3 can be quickly achieved, which greatly improves the assembly efficiency and accuracy, reduces the time cost of manual adjustment and correction, and the rotating sleeve structure between the support column 12 and the upper plate 13 allows the upper plate 13 to be flexibly adjusted in angle, which is convenient to adapt to the combination requirements of flange body 2 and steel pipe body 3 of different specifications and angles, and enhances the versatility and flexibility of the device.

[0022] like Figure 3 and Figure 4As shown, the positioning mechanism 4 includes a cylinder 43 fixedly connected to the lower end face of the upper top plate 13. A rack 42 is fixedly connected to the telescopic end of the cylinder 43. A second slide rail 16 is fixedly connected to the lower end face of the upper top plate 13 above the rack 42, and the rack 42 is slidably sleeved inside the second slide rail 16. A first gear 41 that meshes with the rack 42 is rotatably connected to the center of the lower end face of the upper top plate 13. A fixed shaft 44 is fixedly connected to the center of the upper end face of the first gear 41 through the upper top plate 13.

[0023] Using the above technical solution, the telescopic movement of the cylinder 43 drives the rack 42 to slide smoothly along the second slide rail 16. Through precise meshing with the first gear 41, it realizes the precise angle and position adjustment of the fixed shaft 44 and its lower end connecting parts, ensuring the accuracy and reliability of positioning.

[0024] like Figure 3 and Figure 4 As shown, a disc 45 is fixedly connected to the end of the fixed shaft 44. Several limiting grooves 451 are passed through the arc-shaped array on the upper end face of the disc 45. Several first slide rails 131 are fixedly connected to the upper end face of the top plate 13 in an annular array. A slide frame 46 is slidably sleeved inside the first slide rail 131. A limiting shaft 461 is fixedly connected to the inner top end of the slide frame 46, and the limiting shaft 461 is slidably sleeved inside the limiting groove 451. A side plate 462 for limiting the steel pipe body 3 is fixedly connected to the upper top end of the slide frame 46. Positioning bolts 463 are symmetrically threaded on the outer side wall of the side plate 462. The upper end face of the limiting shaft 461 is flush with the upper end face of the disc 45, and there is a gap between the upper end face of the limiting shaft 461 and the inner top end of the slide frame 46.

[0025] By adopting the above technical solution, the sliding sleeve of the limiting shaft 461 in the limiting groove 451 and the guiding effect of the first slide rail 131 on the slide 46 together constitute a stable limiting system, which effectively prevents the side plate 462 from shifting or shaking during the positioning process of the steel pipe body 3, and enhances the stability and safety of positioning. By sliding the position of the slide 46 on the first slide rail 131 and combining it with the sliding of the limiting shaft 461 in the limiting groove 451, the layout and angle of the side plate 462 can be flexibly adjusted to adapt to steel pipe bodies 3 of different diameters and lengths, thereby improving the adaptability and flexibility of the device. The side plate 462 can achieve a tight fit and firm fixation to the steel pipe body 3 through the fastening action of the positioning bolt 463, preventing movement or damage during subsequent processing or transportation.

[0026] like Figures 1-4As shown, the flange body 2 is placed at the top of the disc 45 and located inside the gap. The steel pipe body 3 is placed at the center of the top of the flange body 2. The outer walls of the two support columns 12 are fixedly connected to the arc plate 15. The lower end face of the arc plate 15 is symmetrically fixedly connected to the reinforcing rod 17. The other end of the reinforcing rod 17 is fixedly connected to the outer wall of the support column 12 connected to the arc plate 15. The outer wall of the upper plate 13 is evenly provided with toothed grooves 14. The upper end face of the arc plate 15 is fixedly connected to the drive motor 5. The output end of the drive motor 5 is fixedly connected to the drive shaft 51. The end of the drive shaft 51 is fixedly connected to the second gear 52 that meshes with the toothed groove 14.

[0027] By adopting the above technical solution, the second gear 52 is driven by the drive motor 5 to mesh with the tooth groove 14, realizing the automatic rotation and positioning adjustment of the upper plate 13 and the flange body 2 and steel pipe body 3 supported below. This greatly improves the automation level and positioning efficiency of the operation, reduces manual intervention, and the design of the reinforcing rod 17 enhances the connection strength between the arc plate 15 and the support column 12, making the entire support mechanism 1 more stable and able to withstand greater loads. This ensures that no deformation or damage will occur during rotation and adjustment, and improves the overall stability and safety of the device.

[0028] Working principle: The flange body 2 is placed on the upper end face of the limiting groove 451. Since the upper end face of the limiting shaft 461 is flush with the upper end face of the disc 45, the inner side wall and the inner top of the slide 46 form a cavity, and the flange body 2 is inside the cavity. The steel pipe body 3 is placed on the upper end face of the flange body 2. Then, the extension end of the cylinder 43 is activated to drive the rack 42 to move linearly under the limitation of the second slide rail 16. Since the rack 42 meshes with the first gear 41, the rotation of the first gear 41 can drive the fixed shaft 44 to rotate, and the fixed shaft 44 drives the disc 45 to move in an arc. When the disc 45 rotates, the limiting groove 451 drives the limiting shaft 461 to pull the slide 46. The synchronous movement of the three sets of slides 46 can limit the flange body 2, and through the side plate 4 The 62 can limit the position of the steel pipe body 3, thereby completing the centering operation of the flange body 2 and the steel pipe body 3. After positioning, the connection can be welded. Then, the drive motor 5 can drive the drive shaft 51 and the second gear 52 to rotate synchronously. At this time, the second gear 52 meshes with the tooth groove 14 on the outer wall of the upper top plate 13, and the upper top plate 13 can rotate. The flange body 2 and the steel pipe body 3 located on the upper end face of the upper top plate 13 will also rotate. After the unobstructed area is welded, the user can release the centering operation of the flange body 2 and the steel pipe body 3, so that the unwelded area can be processed again. This method can not only quickly realize the positioning operation of the flange body 2 and the steel pipe body 3, but also avoid the need for the staff to walk around frequently during the welding work.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
