Cutting cutter head for nuclear industry

The utility model discloses a cutting cutterhead for nuclear industry, which is characterized in that two manipulators respectively grasp two knife rest units, the knife rest units can be clamped and fixed through the correspondence of central columns and central holes on the knife rest units and the correspondence of limiting columns and limiting holes, and then the knife rest units and a cutterhead body are rotationally cut through the manipulators. When the cutterhead body needs to be replaced, the two cutter rest units are loosened, the cutterhead body is taken down through other manipulators, and then a new cutterhead body is installed through the manipulators, so that the cutterhead can be rapidly and effectively replaced, and the problem that the cutterhead body is difficult to replace through the manipulators during connection in an existing bolt mode is effectively solved. 本实用新型公开了一种核工业用切割刀盘，两个机械手分别抓住两个刀架单元，通过刀架单元上的中心柱与中心孔相对应，通过限位柱与限位孔相对应，可以夹住并固定，再通过机械手对刀架单元和刀盘本体进行旋转切割，当需要更换刀盘本体时，两个刀架单元松开，通过其他机械手将刀盘本
