Tool-changing device for machine tools

摘要

A tool changer exchanging tools between a tool magazine and the tool spindle of a machine, in particular a pencil-wheel changer, is equipped with a changing arm (36) which performs the respective removal, insertion and transfer movements, has a double gripper (41, 42) and is provided with a combined reciprocating/rotary drive means (91, 92) which superimposes the reciprocating movements and rotary movements to be performed and considerably reduces the time required for a change operation by reducing the individual motion steps. <IMAGE>
