ABSTRACT:
An automatic tool changer for a machine tool of the type having an upstanding spindle rotatably mounted to a spindlehead for joint vertical displacement therewith between a lower machining position and an upper retracted position via a tool change position therebetween. The tool changer includes an indexing tool magazine rotatable about a fixed slanting axis and carrying a set of cutting tools at prescribed angular spacings for successively bringing them to a position of axial alignment with the spindle. Also included are a chuck control cam for controlling the chucking and unchucking of the successive cutting tools to and from the spindle, and a gripper control cam for actuating a pair of gripper jaws releasably holding each cutting tool on the tool magazine. The tool magazine, chuck control cam and gripper control cam are all driven mechanically from a common drive motor for quick, reliable tool changing operation.
