[0002] In the existing aluminum alloy forged flange technology, manual alignment of mounting holes is mostly used for installation. However, in this way, the flange plate is prone to misalignment during installation. For example, the Chinese patent discloses "a combined aluminum alloy forged flange with corrosion resistance function", with the application number "CN202121438910.X". It uses a limit sleeve, which is installed directly above the second bolt. When the flange head is aligned and installed, a steel pipe can be inserted into the limit sleeve, so that the mounting holes of the second bolt can be aligned. In this way, the alignment position of the flange head can be restricted during installation, avoiding misalignment of the mounting holes and affecting the accuracy of the second bolt installation. However, it requires external tools and auxiliary personnel for positioning, wasting manpower. Content of the Utility Model
