ABSTRACT:
A tool changing device on machine tools, particularly on horizontal boring and milling machines having a drilling spindle. The device includes a dual-arm changing arm rotatable about its horizontal axis and provided on both ends with a grasping device. The changing arm is arranged rotatable on a pivotable pivot arm about an axis of the pivot arm parallel to the changing arm axis. The pivot arm is adjustable in the axial direction. The changing arm carries out rotational movements on the pivot arm during pivoting of the pivot arm (superimposed movements). The grasping device at one changing arm end describes a flat compound curve, or follows the connecting line between the starting and end positions. For fully automatic changing of tools from a drilling spindle and a tool magazine, both grasping devices simultaneously describe a flat compound curve between their starting position and the drilling spindle axis, and their starting position and the tool of the magazine to be grasped, or follow the connecting lines between these parts.
