Description

Technical Field

[0001] This invention relates to the technical field of pipeline construction, and in particular to a tooling for aligning and machining the flanges of a bellows compensator. Background Technology

[0002] Bellows compensators are a type of compensating element. They utilize the effective expansion and contraction deformation of their main working body, the bellows, to absorb dimensional changes in pipelines caused by thermal expansion and contraction, or to compensate for axial displacement of pipelines, ducts, containers, etc. They are widely used in pipeline construction.

[0003] Currently, there is one type of bellows compensator available on the market, as shown in the instruction manual. Figure 6 It includes a screw, a bellows body, and flanges located on the upper and lower sides of the bellows body, both of which have holes. Since the bellows compensator is mainly installed at the connection point of two pipes, and during pipeline construction, to ensure the smoothness of the pipeline and the stability of the medium transport within it, the two pipes to be connected must be coaxial. The bellows compensator connects to the two pipes through its two flanges, so during the production of the bellows compensator, the flanges on both sides must be coaxially aligned.

[0004] Currently, during the processing and connection of the aforementioned bellows compensators, as per the instruction manual... Figure 7 First, place the bellows on the lower flange. Then, weld the lower part of the bellows to the lower flange. Next, insert multiple bolts into the holes of the lower flange. Then, use nuts to fix the bolts to the lower flange. Next, place the upper flange on the upper end of the bellows, and pass the upper parts of the bolts through the holes of the upper flange. Then, use nuts to fix the upper parts of the bolts to the upper flange. Finally, weld the upper flange to the upper part of the bellows.

[0005] During the processing and installation of the aforementioned bellows compensator, it was found that the coaxiality of the upper and lower flanges was only ensured by inserting multiple screws into the holes of the two flanges. However, the diameter of the holes is larger than the diameter of the screws, so there will be a certain amount of play between the screws and the holes. Therefore, relying on the insertion of screws into the holes on both sides to ensure the coaxiality of the upper and lower flanges is unreliable. The coaxiality of the upper and lower flanges is low, and the installation accuracy is poor. Therefore, a tooling is needed that can align and coaxially align the upper and lower flanges during the installation of the bellows compensator. Summary of the Invention
