    • A machining center of the type incorporating a spindle for driving tools wherein the spindle is movable rectilinearly along the axis of the spindle for engaging tool holders to move tool holders, and tools secured thereto, into an operative position wherein the tools contact a work piece. The rotational speed of the spindle, as well as its rectilinear motion, is controlled by a programmed numerical control center which also controls the bed upon which the work piece is mounted; the bed is movable, at predetermined rates, in the X, Y and Z directions. A positioning means, such as turret or carousel, is positioned beneath the spindle and is used to hold several tool holders, each of which supports tools for use in the machining operation. The tool holders are temporarily secured in the positioning means and are removed therefrom through the operation of the lowering spindle; the tool holders are formed in three sections, the first of which contacts and is driven by the rotating spindle. The second section of the tool holder is held against rotation by an anti-rotation device which operates through a coupling secured at one end to a vertically movable ram and at the other end to the second section of the tool holder. The tool holder also includes a third section that incorporates a tool holding spindle; the first section and the third section of the tool holder are interconnected by a drive coupling that permits significant variations from the conventional spindle rotational velocity and rectilinear motion. Selected drive couplings are provided for three dimensional angular displacement of the tool holding spindle relative to the rotational axis of the spindle on the machine center. Further selection of the drive coupling in the machine tool permits the simultaneous use of multiple tools, the utilization of multiple tools rotating about an axis perpendicular to the axis of the spindle, and rotational velocities of tools in excess of the rotational velocity of the driving spindle.

    • A tool clamping device for multiple-operation machines or machining centers. The device has a self-blocking fork for selectively securing a tool on a tool changing device or autooperator, the fork being in the shape of jaws which partially embrace the shank of a tool. In both arms of the fork there are profile grooves in which there are located pivotally mounted blocking pins. Between the blocking pins and the bottom wall of the grooves there are springs for constantly pressing the blocking pins toward their blocking position. The blocking pins are L-shaped, and in their blocking position the end of one arm of each protrudes outwardly in position to be engaged by the face keys of the spindle of the machine in the operation of removing a tool from the spindle of the machine.
    • 用于多操作机床或加工中心的工具夹紧装置。 该装置具有用于选择性地将工具固定在换刀装置或自动操作器上的自锁叉,所述叉子是部分地包围工具的柄部的钳口形状。 在叉的两个臂中都有轮廓槽,其中定位有枢转安装的阻塞销。 在阻塞销和槽的底壁之间有弹簧,用于不断地将阻塞销压向其阻挡位置。 阻塞销是L形的,并且在它们的阻挡位置中,一个臂的端部向外突出到适当位置,以在从机器主轴移除工具的操作中与机器的主轴的面部键接合 。
