ABSTRACT:
A workpiece clamping apparatus for clamping various types of workpieces comprises a pair of finger members adapted to be moved toward and away from each other, a first command position setting device for setting a first command position according to the outer configuration of a workpiece to be clamped, a second command position setting device for setting a second command position closer to the position of the workpiece than the first command position and, a driving device for moving the finger members to the second command position past the first command position. A first clamping force setting device sets the workpiece clamping force to be exerted by the finger members to a first clamping force level during movement of the finger members from the first command position to the second command position, and a second clamping force setting device sets the workpiece clamping force to a second clamping force level which is different from the first clamping force level during the movement of the finger members towards the first command position.
