Before processing the three paddle surfaces, the bottom surface needs to be processed as a reference plane, so that the three paddle surfaces can be processed. At present, the horizontal machining center has the following difficulties in processing the wheel hub: based on the processing characteristics of the machining center, the bottom surface needs to be perpendicular to the worktable, and the bottom surface processing tool must be parallel to the processing. Since the angles between the three blade surfaces and the bottom surface are all 86.5 If the blade surface is directly fixed to the worktable of the horizontal machining center, the bottom surface is not parallel to the processing tool, the bottom surface and the holes on the bottom surface cannot be processed, and only one blade surface can be processed at a time. For the other two blade surfaces, it is necessary to remove the hub of the wind turbine from the fixture, and then process the other two blade surfaces, which brings great inconvenience to the processing. In order to solve the above problems, this application proposes a A fixture for clamping the hub of a wind turbine.

At present, the existing clamps for clamping the hub of the wind power generating set are inconvenient to use and are not conducive to popularization and use.
