ABSTRACT:
A tool change mechanism for horizontal drilling-milling machines comprising a magazine, a tool spindle, the tools being arranged substantially horizontally and at right-angles to the tool spindle in the magazine. A gripper rocker having a gripper rocker shaft disposed substantially parallel to the work spindle is mounted in a gripper carriage, said gripper carriage being displaceable in the direction of the work tool spindle for the introduction and the removal of the tools, said gripper carriage possessing a double pivotal gripper vane rotatable through an angle of approximately 180.degree.. Guide tracks are arranged at the magazine, said gripper carriage being displaceable at the guide tracks by means of two coupled drives into at least four positions, one drive being attached at the gripper carriage and one drive being stationarily supported in the direction of the guide tracks. A gripper arm carrying the gripper vane is pivotably mounted at the gripper rocker such that its gripper arm shaft is directly and non-displaceably mounted in the gripper rocker and the gripper arm shaft and its extension intersects in spaced relation and at substantially right-angles the gripper rocker shaft. The gripper rocker and the gripper arm are pivotable such that the symmetry axes of the gripper tongs of the gripper vane in a magazine position of the gripper vane are directed substantially parallel to the tool spindle and in a tool spindle position of the gripper vane the symmetry axes of the gripper tongs located at the tool spindle are disposed at right-angles to the tool spindle as well as at right-angles to a connection line between the gripper rocker shaft and the tool spindle shaft at the center point of the tool spindle shaft.
