ABSTRACT:
A mechanical interface for joining a gripper to a robot wrist of the type having a shaft projecting outwardly as the distal member of a robot arm. The interface includes a sleeve having an internal nut or flange for properly locating the sleeve with respect to the shaft. At this location, a bevel gear at the end of the shaft engages a similar gear within the sleeve so that the sleeve is locked to the shaft. The bevel gear within the sleeve is supported by a spring so that outward force from the sleeve allows separation of the gears and disconnection of the coupler from the shaft. Internal fluid passageways within the sleeve allow transmission of fluid pressure from the shaft to a connected gripper for transmitting power, control signals or sensing signals between the robot arm and the gripper.
