Description:

Abstract:

An improved shuttle type automatic tool changer is disclosed in the environment of a multi-purpose horizontal spindle machine tool and is adapted to effect the transfer of a succession of tools between a remote tool storage matrix and the machine spindle. The tool changer operates with simple shuttle motions, carrying the tool through a relatively long rectilinear path parallel to the spindle and a substantially shorter orbital path which intersects the axis of the spindle, and utilizing tool handling elements which maintain precise control of the position and orientation of the tool throughout the transfer movement. The tool changer is mounted on the machine tool as a unitary assembly adapted for operation through the numerical control system of the machine.
