Abstract
A tool changing assembly for program controlled milling and drilling machines comprising a vertically movable knee-type unit for the work table, and a vertical milling head. The tool changing assembly includes a power-driven pivotable mounting which is arranged in the form of a bracket for pivoting movement about a vertical axis on a column mounted on the knee-type unit laterally spaced from the work spindle of the milling head. The free end of the bracket has gripping pliers mounted thereon for pivoting movement about a likewise vertical axis, the pivoting movement of the gripping pliers being opposite to the pivoting movement of the bracket and being derived therefrom.
