Description

Technical Field

[0001] This utility model relates to, and more particularly to, an integrated modular welding fixture for multi-flange connection pipes in spatial positions. Background Technology

[0002] The connection between centrifugal pumps usually requires multiple pipelines. The two pumps are in a relative spatial position and connected by pipelines. The connecting pipeline between the two pumps is an S-shaped multi-section bend, with welded flanges at both ends and bolted to the pumps. Additionally, a 90-degree bend is connected to each side of the lower centrifugal pump, with a flange at each end. During installation, the rigid connection has high requirements for the interface dimensions. Due to the relatively large component size, the S-shaped multi-section bend consists of a straight pipe in the middle, bends at both ends, and two flanges, with the two flange faces perpendicular at 90 degrees. Furthermore, the axes of the three pipes are not on the same plane, making assembly difficult and prone to deformation after welding. Secondly, the lower connection 90-degree bend consists of one bend and two flanges, with the two flange faces perpendicular at 90 degrees. The horizontal flanges on both sides of the lower connection must be on the same horizontal plane with dimensional limitations. Current assembly is all manual, resulting in low control over installation position and dimensions, easily causing deformation during the assembly of the S-shaped and 90-degree bends, leading to a high scrap rate and low installation efficiency.

[0014] like Figure 1 , 2 The diagram shows an integrated modular welding fixture for multi-flange connecting pipes in a spatial configuration. It comprises a plate connector (19) and a profile frame component (20). The plate connector is used to control the relative dimensions and positions of the components and for fixation.

The flange on Pump 1 (21) is connected to plate connector 19 via a connecting pipe, and the flange on Pump 2 (22) is connected to profile frame component 20 via a connecting pipe. Other flanges on Pump 1 (21) and Pump 2 (22) are connected via pipes.

[0016] like Figure 1 , 2 As shown in the figure, the plate connecting part 19 includes a back plate 9 as a reference. The back plate 9 is T-shaped. The upper horizontal plate is provided with a flange connecting plate 2 for connecting the flange 23 of the pump 21 and a flange connecting plate 1 for connecting the flange 24. In the middle of the back plate 9, there is a support panel 3 for connecting the pump 21. The lower end of the support panel 3 is provided with a support plate 31. At the bottom of the back plate 9, there is a support panel 5 for connecting the pump 22. The support panel 5 is connected above the bottom plate 7 connected to the bottom of the back plate 9. A support plate 6 and a vertical plate 8 are connected between the support panel 6 and the bottom plate 7. The support panel 3 and the support panel 5 are provided with bolt positioning holes 10 for fixing the connection of the pump 21 and the pump 22.

[0017] like Figure 1 , 2 As shown in the figure, the profile skeleton part 20 includes a flange skeleton support part 17, a column 16, a skeleton triangular support part 15, and a skeleton support part 18 formed by welding 100*100 square tubes. After being welded with the plate connecting part, it plays a role in rigid reinforcement. The flange skeleton support part 17 is located at the upper end of the column 16, and the skeleton triangular support part 15 and the skeleton support part 18 are located on the front side of the column 16. It also includes a left staircase 11 and a right staircase 14 set on both sides of the column 16. The left staircase 11 and the right staircase 14 are set to facilitate working at height. The lower end of the skeleton support part 18 is provided with a flange connection seat support plate 12, and flange connection seat one 4 and flange connection seat two 13 are provided at both ends of the flange connection seat support plate 12.

[0018] Flange 3 25 on pump 1 21 is connected to flange 5 27 on pump 2 22 via upper left connecting pipe 32. Flange 4 26 on pump 1 21 is connected to flange 6 28 on pump 2 22 via upper right connecting pipe 33. Flange 7 29 on pump 2 22 is connected to flange connecting seat 1 4 via lower connecting pipe 1 34. Flange 8 30 on pump 2 22 is connected to flange connecting seat 2 13 via lower connecting pipe 2 35.

[0019] The upper left connecting pipe 32 and the upper right connecting pipe 33 are S-shaped multi-section bends.

[0020] The overall structure is not only used for assembling and welding the connecting pipes on pump 1 21 and pump 2 22, but also serves as the assembly tooling for the entire component. This allows for welding without disassembly after assembly, ensuring assembly quality, improving production efficiency, and guaranteeing a first-time inspection pass rate for the product.

[0021] Tooling Fabrication: The tooling consists of a sheet metal connector part 19 and a profile frame part 20. The sheet metal connector part 19 is used to control the relative dimensions and positions of the various parts of the component and to fix them. The connection method is a mortise and tenon structure, which can ensure the dimensional accuracy and structural stability of each part. In order to enable the positioning of each component in three-dimensional space, the reference positioning plate is the back upright plate 9, which can be positioned in the vertical and horizontal directions. The flange direction is positioned by extending the upright plate. Therefore, some mortise holes and screw holes are designed on the surface of the back upright plate 9 for positioning of each component. The following parts are connected to the back upright plate surface by tenons or bolts: flange connecting plate 12 for connecting flange 23 on pump 1 21, flange connecting plate 21 for connecting flange 24, support plate 13 for connecting pump 1 21, support plate 25 for connecting pump 2 22, vertical upright plate 8, base plate 7, and support upright plate 26. In this way, the parts are connected to each other by mortise and tenon to ensure the dimensional accuracy of each part. The profile skeleton is constructed from 100*100 square tubing welded together, and its welding with the plate connector reinforces the profile. Pump 1 21 and Pump 2 22 are placed on and connected to the plate connector 19, and are connected to each other via the upper left connecting pipe 32 and the upper right connecting pipe 33. Pump 1 21 and Pump 2 22 are connected to the profile skeleton 20 via the lower connecting pipe 1 34 and the lower connecting pipe 2 35.

[0022] like Figure 5 As shown, during assembly, first suspend pump 21 on support panel 3, aligning the base bolt holes with the corresponding four bolt positioning holes on support panel 3. Simultaneously, align the two flanges 23 and 24 on the upper end of pump 21 with the holes on the connecting plates 2 and 1 on the upper end of tooling pump A, and tighten them with bolts. Then suspend pump 22 on support panel 5, aligning the base bolt holes with the corresponding four bolt positioning holes on the support panel, and tighten them with bolts. At this point, the two centrifugal pumps are in place. Next, assemble the lower connection part. First, connect and fix the lower connecting pipe 34 to the upper flange 29 of pump 22 with bolts. Then, adjust the position of the 90-degree bend and flange connecting seat 4, adjust the position appropriately, and connect and fix it to the lower flange connecting seat 4 of pump 22 with bolts. Assemble the other lower connection part in the same way. Next, assemble the upper connecting parts. First, install the upper flange of the upper left connecting pipe 32 onto flange 25 of pump 1 21 and flange 27 of pump 2, and tighten the bolts. Then, insert the elbows at both ends into the flange holes as shown in the diagram, and connect them with the middle straight pipe. After appropriate trimming and angle adjustment, connect the three pipes to the flanges as a whole. Assemble the other upper connecting part in the same way. At this point, the assembly of the entire component is complete. Then, weld the connecting parts without disassembling. This ensures assembly quality, improves production efficiency, ensures the first-pass yield of the product, and avoids repetitive disassembly and reassembly.
