摘要： This invention relates to an improved three-point support subassembly for pivoted machine tool turntables that is characterized by a pair of floating pads retained in cavities on the underside of the turntable that slide along the opposed planar surface of a stationary bedplate therebeneath and a ball and socket pivotal connection that allows the turntable to swing on a vertical axis defined by the latter as well as tilt relative thereto. The stem portion of the pin is journalled for rotation about a vertical axis in the bedplate while the spherical portion atop said stem is connected to the turntable for conjoint movement in a horizontal plane due to a loose fitting coupling therebetween. The socket journalling the spherical portion of the pivot pin includes upper and lower segments independently adjustable relative to one another and to the turntable for purposes of leveling the latter. Adjustable abutments also engage the pads and are used to raise or lower the turntable relative thereto.
