ABSTRACT:
A work changing mechanism for machine tools, especially lathes, designed for automatic change of works to be clamped by centers or chucks comprising a shuttle car movable in the direction of the spindle axis of the lathe, a slide vertically movable along the shuttle car and rotatably arranged on the slide and about a horizontal shaft extending transversely to the spindle axis is a gripping mechanism including two pairs of jaws which are horizontally displaceable parallel to the shaft on opposite sides thereof. The first jaw pair is adapted to feed work into the machine tool and the second pair to remove machined work from the machine tool. Loading and removing work pieces may be rapidly achieved because the work changing mechanism is controlled by computer.
