    摘要： A guided member is engaged with a guiding member and the guided member and guiding members are movable relative to each other. A pair of planar, parallel guide surfaces on the guide member are engaged by a pair of bearings mounted on the guided member. One of the bearings is resiliently biased into engagement with the guide surface which is less precisely formed so that irregularities in that guide surface or lack of parallelism between the guide surfaces is accommodated by displacement of the biased bearing. The bearings are mounted on bearing supports which depend from either side of a cross piece. The cross piece is secured to the guided member such that a portion of the cross piece is uncoupled from the guided member and is free to be deflected, thus providing the biasing for the biased bearing without transmitting stress to the guided member. Preferably, the apparatus is employed in a machine tool to guide the movement of a worktable.

    摘要： A multi-station apparatus for drilling closely-spaced holes in a plurality of workpieces while individually supported by a turntable. A frame supports the turntable with their axes of rotation extending vertically such that two of the turntables lie within one of two spaced-apart vertical planes and the two remaining turntables lie within the other vertical plane. Parallel line shafts extend horizontally below the turntables and carry bevel gears that mesh with other bevel gears secured to the turntables. The line shafts are interconnected by a train of spur gears that are, in turn, rotated by a handwheel having a pin extending into an indexing plate for locking the gear drive and thereby holding the turntables in a desired adjusted position. The vertical columns extend above the turntables at horizontallyspaced locations such that the turntables lie between the columns. Each column carries a radial arm with its extended end carrying pairs of drill means, one for each turntable. Piston and cylinder assemblies advance the drill means toward a workpiece while supported on the turntable and stops are provided to limit displacement of the drill means.

    摘要翻译： 一种用于在多个工件中钻出紧密间隔开的孔的多工位装置，同时由转台单独支撑。 框架支撑转盘，其旋转轴垂直延伸，使得两个转盘位于两个间隔开的垂直平面之一中，并且剩下的两个转盘位于另一垂直平面内。 平行线轴水平延伸在转盘的下方，并带有与固定在转台上的其他锥齿轮啮合的锥齿轮。 线轴通过一系列正齿轮相互连接，这些正齿轮通过手轮旋转，手轮具有延伸到分度板中的销，用于锁定齿轮传动，从而将转盘保持在期望的调节位置。 垂直柱在水平间隔的位置上延伸到转台上方，使得转盘位于柱之间。 每列都带有一个径向臂，其延伸端带有一对钻孔装置，一个用于每个转台。 活塞和气缸组件在支撑在转盘上的同时将钻孔装置朝向工件推进，并且设置挡块以限制钻孔装置的位移。
