    • A turret of a lathe has a power transmission that is used for moving a tool Disk secured on a shaft to a secured position where the disk is engaged with a clutch. The transmission includes a piston, and a force multiplier unit, which includes a ring, a sleeve secured to the piston, and steel beads. The ring has first sloping trenches. The sleeve has sloping trenches that are less steep and opposing the first trenches, and has recesses connected to the trenches. The steel beads are held in respective ones of the spaces defined by the sloping trenches and the recesses, and are positioned next to a gear secured on the shaft such that when the piston is actuated for moving the tool disk towards the secured position, the steel beads will push the gear with multiplied force output while being rolled along the sloping trenches.
    • 车床的转塔具有用于将固定在轴上的工具盘移动到盘与离合器接合的固定位置的动力传动装置。 变速器包括活塞和力乘数单元,其包括环,固定到活塞的套筒和钢珠。 戒指有第一个倾斜的沟槽。 套筒具有较小的斜坡并且与第一沟槽相对的倾斜沟槽,并且具有连接到沟槽的凹陷。 钢珠保持在由倾斜沟槽和凹部限定的空间中的相应一个空间中,并且紧邻固定在轴上的齿轮,使得当活塞被致动以将工具盘移动到固定位置时,钢 当沿着倾斜的沟槽滚动时,珠子将以倍增的力输出推动齿轮。

    • An indexing system for the rotary work changer of a machining center for supporting and interchanging work-holder pallets between the machining zone and the load/unload zone of the machining center. The indexing system comprises a hydraulically powered rotary actuator attached to the work changer and having first and second ports, a hydraulic fluid pressure line and a hydraulic fluid return line, a directional valve for connecting the hydraulic fluid pressure line to either one of the first and second ports of the actuator depending on the desired direction of rotation of the work changer, and for connecting the other of the actuator first and second ports to the hydraulic fluid return line, a control valve connected between the actuator first and second ports and the directional valve to regulate the flow of return fluid from the actuator so as to cause the work changer to accelerate, reach a maximum speed and then decelerate to a slow speed just before reaching the desired one of its first and second positions.
    • 一种用于在加工区域和加工中心的加载/卸载区之间支撑和交换工件托盘的加工中心的旋转工作转换器的分度系统。 分度系统包括一个液压动力旋转致动器,其连接到工作变换器上并具有第一和第二端口,液压流体压力线和液压流体回流管线,用于将液压流体压力管线连接到第一和第二端口 致动器的第二端口根据所需的工作转换器的旋转方向,并且用于将致动器第一和第二端口中的另一个连接到液压流体返回管线,连接在致动器第一和第二端口之间的控制阀和定向 阀,以调节来自致动器的返回流体的流动,从而使换档器加速,达到最大速度,然后在达到其第一和第二位置期望的一个之前减速到慢速。

    • A new and improved indexing table for supporting a workpiece on a machine tool and the like includes a base with a workpiece supporting table carried on a support shaft journaled for rotation to index the workpiece for machine tool operations. A drive system is provided for rotating the table in one direction about a longitudinal axis of the support shaft and an indexing wheel is provided on the shaft having a plurality of index slots spaced angularly around the periphery for securing the table in selected indexing positions. A shot pin is provided for engaging selected slots in the wheel to lock the table in a fixed position and when the shot pin is retracted, the table is then permitted to rotate toward a next indexing position. Removable stops are insertable into the index wheel at selected positions corresponding to index slots therein and the stops in combination with a stop system are effective to arrest rotation of the workpiece and supporting table as the table is rotationally indexed toward and reaches a next selected index position.
    • 用于在机床等上支撑工件的新的和改进的分度台包括具有承载在支撑轴上的工件支撑台的基座,所述支撑轴被轴颈旋转以对工件进行索引以用于机床操作。 提供驱动系统,用于围绕支撑轴的纵向轴线在一个方向上旋转工作台,并且转轴设置在轴上,转位轮具有围绕周边成角度地间隔开的多个分度槽,用于将工作台固定在选定的分度位置。 提供了一个弹簧销,用于接合车轮中的选定的槽,以将工作台锁定在固定位置,并且当弹簧销缩回时,该台允许转向下一个分度位置。 可拆卸的止动件可以在与其中的分度槽相对应的选定位置处被插入到分度轮中,并且与止动系统组合的止动件有效地阻止工件和支撑台的旋转,因为工作台被转动地向下并且到达下一个选定的分度位置 。
