[0002] Flanges are important components for connecting pipes, valves and other equipment. They are widely used in many fields such as energy, chemical industry, petrochemical industry, metallurgy, construction and shipbuilding. These fields have extremely high requirements on the processing accuracy and assembly efficiency of flanges. Especially under high temperature and high pressure conditions, the sealing and reliability of flange connections are crucial.

[0003] After searching, the invention patent with Chinese patent number CN109483271B discloses a processing tool for flange positioning holes. Compared with the existing technology, the invention patent with Chinese patent number CN109483271B uses a positioning fixture to fix the flange to prevent the flange from shifting. The flange is sleeved on the fixing tube, and then the fixture is clamped on the upper end of the flange by an electric cylinder to prevent the flange from loosening. The coordinated use of the laser head and the fixture improves the accuracy of the flange drilling position.

[0004] However, during the actual use of the above-mentioned device, when the positioning fixture fixes the flange, it only fixes it from one place of the flange, which makes it difficult for the positioning fixture to clamp and fix flanges of different widths. The flange is fixed in position by a fixing tube, which limits the types of flange fixation. Therefore, it is necessary to propose a flange processing and fixing tool. Summary of the invention
