Large-outer-diameter thin gear ring segmented machining equipment and process thereof

The invention relates to large-outer-diameter thin gear ring segmented machining equipment and a process thereof. The large-outer-diameter thin gear ring segmented machining equipment comprises a workbench, a stand column is arranged on one side of the workbench, a cutting mechanism used for cutting a tooth groove of a gear ring is arranged on the stand column, and a fixing mechanism used for fixing a part is arranged on the other side of the workbench. The fixing mechanism comprises a moving plate and a rotating plate, the moving plate is slidably arranged on the workbench in the direction close to or away from the cutting mechanism, the rotating plate is parallel to the table top of the workbench, and a driving device used for driving the rotating plate to ascend, descend and rotate is arranged on the moving plate. A plurality of connecting rods are arranged on the edge of the rotating plate, an electromagnet is arranged at the end, away from the rotating plate, of each connecting rod, a fixing groove for p
