    • A rotary indexing machine comprising a housing, a spindle mounted for rotation in the housing, an index plate mounted on the spindle substantially coaxially therewith, means for mounting a workpiece-holding member substantially coaxially with the spindle, a fluid motor for continuously rotating the spindle in one direction about its axis, the motor being located within the housing substantially concentric with the spindle and positioned between the index plate and the means for mounting the workpieceholding means, means for periodically arresting rotation of the spindle for a predetermined interval of time during which the workpiece may be machined, and means for periodically releasing the rotation arresting means. The means for periodically arresting rotation of the spindle for automatic step indexing, may be easily rendered inoperative so that thereafter the spindle will be rotated continuously without step indexing. The preferred embodiment also includes means for moving the spindle axis through an arc relative to a horizontal position and means for adjusting the spindle angularly about its axis and relative to the location plane of the index plate, whereby the location sides of the notches of the index plate may be accurately aligned with premachined notches existing in the workpiece.
    • 一种旋转分度机,包括壳体,安装成用于在壳体中旋转的主轴,与主轴同轴安装的分度板,用于安装与主轴大致同轴的工件保持部件的装置,用于连续旋转主轴的流体马达 沿着其轴线的一个方向,电动机位于壳体内与心轴基本同心并且位于分度板和用于安装工件保持装置的装置之间,用于周期性地阻止心轴的旋转预定间隔时间的装置 在此期间可以加工工件,以及用于周期性地释放旋转止动装置的装置。 用于定期地阻止主轴旋转以进行自动步进分度的装置可能容易地变得不可操作,从而此后主轴将在没有阶跃分度的情况下连续旋转。 优选实施例还包括用于使主轴轴线相对于水平位置移动电弧的装置,以及用于相对于折射板的位置平面相对于其轴线和相对于折射板的位置平面角度地调节主轴的装置,由此指示凹槽的位置侧 板可以精确地对准存在于工件中的预加工凹口。
