<p>The device for changing tools operated by a robot comprises a coupling head mounted at the end of the arm of the robot and interacting with a coupling member of the tool, connection elements being carried by the coupling head of the robot and the coupling member of the tool to ensure continuity of the lines supplying power to the tool. The coupling head of the robot arm has a central clamping piston (12) fitted into a bore (32, 33) of the tool, this piston being subject to springs intended to clamp the coupling and which are compressed for unclamping and the connection members (40, 50, 60) are arranged around the said gripping piston. <IMAGE></p> |
