Abstract

An automatic tool-changing device for industrial robots includes a gripper member located at the end of the robot arm and a coupling flange to which a tool is fixed. The gripper member has radially-movable engagement teeth adapted for insertion in projecting appendages carried by the flange, upon automatic clamping of the tool. The movement of the engagement teeth is driven by a pressurized-fluid jack housed in the gripper member.
