PURPOSE:To eliminate the excessive stroke of the robot wrist and to perform the change of a robot hand in a short time by providing a cam plate driven by its rotation as the mechanism extruding a steel ball. CONSTITUTION:The tip of a robot wrist 10 is fitted to the specified part of a hand 30. A polygonal cam plate 20 is then rotated by a driving means 13 and several steel balls abutting to this cam face are moved in the radial direction. The hand 30 is firmly held on the robot wrist 10 by firmly engaging these steel balls 16 with the taper face 32B of the hand 30. The hand 30 can thus be changed by detaching it quickly for the robot wrist 10 tip by the action of the cam plate 20. |
