ABSTRACT:
A robot hand for gripping workpieces to be forged which are subjected to impact loads is provided. The robot hand 2 includes a grip 3 for gripping a workpiece to be forged and a grip support 2a for supporting the grip 3. A grip guide 12 for supporting the grip 3 so that it is movable in a plane perpendicular to the longitudinal axis of the grip support and slidable in forward and rearward directions and a spherical seat 5 for bearing the grip guide 12 so that it can be inclined are provided within a casing 4 of the grip support 2a. The casing 3 of the grip support 2a is provided with various actuators 9, 10, 11, 7 for changing the supporting state between a state in which the grip 3 can be moved and inclined and a state in which the grip 3 can not be moved and inclined. The grip 3 is brought into the movable and inclinable state for absorbing an impact when the impact load is applied to the gripped workpiece to be forged.
