Abstract:
An apparatus for radially adjusting a position of a plurality of tool cartridges of a machine tool having rotatable, concentric, elongate, inner and outer drive spindles with a plurality of pockets formed in the outer drive spindle exposing a portion of the inner drive spindle, the apparatus comprising:a wedge disposed in each pocket for movement relative to the longitudinal axis of the elongate inner drive spindle in response to relative rotation of the inner drive spindle with respect to the outer drive spindle when the inner drive spindle is in a predetermined selectable position with respect to each pocket;a rotatable member disposed in each pocket operably connected to the wedge and being selectively operably engageable with a portion of the inner drive spindle to cause rotation of the rotable member in response to rotation of the inner drive spindle with respect to the outer drive spindle when the inner drive spindle is in the predetermined selectable position with respect to each pocket, the rotatable member having a threaded external surface operably engagable to move the rotatable member longitudinally in response to rotation of the rotatable member; anda tool cartridge operably engaged within each pocket of the outer drive spindle for radial movement relative to the longitudinal axis of the outer drive spindle in response to relative movement of the corresponding wedge.
