The invention discloses a 
numerical control lathe mechanical hand suitable for production of disc type parts. The 
numerical control lathe mechanical hand comprises a base, a 
servo motor, two paw cylinders, a clamping mechanism, a rotating arm, a speed 
reducer, clamping paws, clamping arms and a cylinder, wherein a housing is mounted on the base, the 
servo motor and the speed 
reducer are sequentially mounted in the housing from bottom to top, and a main shaft of the speed 
reducer is connected with the rotating arm; one end of the rotating arm is sheathed on the main shaft of the speed reducer,and the two paw cylinders and the clamping mechanism are outwards sequentially mounted at the other end of the rotating arm from the main shaft of the speed reducer; and the two pairs of the clampingpaws in the clamping mechanism are respectively mounted at one end of the each of the respective clamping arms, and the other end of each clamping arm is connected with the respective paw cylinder. The 
numerical control lathe mechanical hand firstly realizes full-automatic transportation operation of feeding and discharging when a numerical control lathe is used for 
processing the disc type parts, has the advantages of simple structure, reliability in control, precise positioning and the like, and can further replace two workers for performing clamping and transportation work on the disc-shaped parts during feeding and discharging, greatly reduce the cost and improve the efficiency and the safety.
