Tool changer for manipulator arm

Abstract

A tool changer for use with the manipulator arm of a robot or the like. A tool changer in which the manipulator arm is engaged with the end effector carrying the tool by a simple linear motion, and disengaged by a linear motion in the opposite direction, without requiring any separate control functions such as switch actuation or the like. A tool changer which also provides for transmitting mechanical, electrical or fluid power and/or control between the manipulator arm and the end effector, and one which can be utilized with any type of tool, sensor, transducer, and the like. A tool changer incorporating a coupling which is closed by an axial compression force and opened by an axial tension force, and an end effector rack for receiving and supporting a plurality of end effectors so that a manipulator arm can position an end effector in the rack with a lateral movement, disengage the arm from the end effector with an axial movement, engage the arm with another end effector by an axial movement in the opposite direction, and remove the new end effector by a lateral movement.
