    摘要： A grinding fixture has a rotatable workpiece-holding spindle which may be indexed at any selected angular division of a circle, utilizing at least two circumferentially spaced indexers radially insertable into and retractable from the interspaces between adjacent teeth spaced at ten degree intervals around the circumferential face of an associated rotatable spindle. The indexed angle is determined by the circumferential spacing of the indexers with respect to the interspaces. Either a collet, scroll chuck or V-block may be used to mount the workpiece on the fixture.

    摘要： A method of testing the concentricity of the stator bore of an electrical machine as the stator lamination layers conjointly defining the bore are stacked is disclosed. Each layer is made up of several lamination sections having respective inside edges at the bore surface. The housing of the machine is centered with respect to the longitudinal axis thereof and is equipped with an end plate and a thrust ring at the excitation side and drive side of the machine respectively. The method includes the steps of arranging markers at equal spacing on a circle described on the end plate so as to be concentric with the longitudinal axis. Markers are also arranged at equal spacing on the thrust ring. The inside edges of the lamination sections are sensed with a sensing and measuring gauge to measure the distance between the inside edge of each lamination section and markers corresponding to the section being sensed. An apparatus for performing the method is also disclosed and includes a sensing and measuring gauge engageable with the markers corresponding to the section sensed to measure the distance between the edge of the section and the markers.

    摘要： Dividing attachments for angular indexing in which the attachment is provided with two coaxial plates, in one of which spherical indentations extend along a circumference, while in the other balls are fixed for entering the indentations of the first plate. The indentations are made by compacting the material of the plate to a depth which is less, than their radius, and the balls are pressed into the plate to a depth which exceeds their radius, and are embedded in the plate. The attachment is intended to be employed mainly in metalworking machines and in jigs used therewith.

    摘要： DRIVING AND DRIVEN SHAFTS ARE SUPPORTED IN BEARINGS WHICH ARE PERMANENTLY SPACED APART AT A DEFINITELY FIXED CENTER DISTANCE. ON THE DRIVEN SHAFT IS A FIRST SUPPORT IN THE FORM OF A FLANGE FOR A CIRCLE OF CAM-FOLLOWER ROLLERS. ON THE DRIVE SHAFT IS A SECOND SUPPORT IN THE FORM OF A FLANGE FOR A CAM MEANS WHICH DRIVE THE FOLLOWER ROLLERS AROUND SAID CIRCLE. EACH ROLLER IS BORNE UPON A STUD WHICH EXTENDS THROUGH A FLANGED BUSHING. EACH BUSHING CLOSELY BUT ROTATABLY AND REMOVABLY FITS INTO A HOLE IN SAID FIRST SUPPORT AND ITSELF HAS AN ECCENTRIC HOLE THERETHROUGH. EACH STUD IS LOCATED IN ONE OF THESE ECCENTRIC HOLES. EACH STUD ALSO HAS A STOP AT ONE END FOR ENGAGEMENT WITH THE FLANGE OF THE BUSHING, AND IS THREADED ON ITS END OPPOSITE TO RECEIVE A DRAW NUT REACTING AGAINST SAID FIRST SUPPORT FOR CLAMPING THE FLANGE OF THE BUSHING THERETO, THEREBY TO HOLD THE BUSHING IN ANY SELECTED ANGULAR POSITION ON THE SUPPORT. BY LOOSENING THE NUT THE BUSHING IS RELEASED FOR ROTARY ADJUSTMENT OF THE POSITION OF THE CENTER LINE OF THE ROLLER WHICH IT SUPPORTS, WHEREBY THE RADII OF THE CENTERS OF ANY OR ALL OF THE ROLLERS MAY BE CHANGED. EACH AND EVERY BUSHING, STUD OR ROLLER, IF DAMAGED, IS REPLACEABLE IN ITS SUPPORT, THE SUPPORT BEING PROTECTED AGAINST DAMAGE SO THAT ITS REPLACEMENT IS NOT NECESSARY IN SUCH AN EVENT.

    摘要： An apparatus and method for rotationally moving and positioning a work piece such as for dividing the workpiece into a predetermined number of equal segments. The movement is accomplished by repeatedly angularly displacing the work piece over a given swing increment of angular movement. The angular swing increment is established by summing angular displacements of each of a plurality of circular plates, each plate divided into a different number of equal segments. By a proper choice of the number of segments into which the plates are divided, and of the number of segments each plate is displaced, the angular increment can be established with extremely high precision. The angular increment may be greater than the distance between adjacent intended segments into which the work piece is divided. This allows distribution of the error of the angular increment established for each movement of the work piece about the entire periphery of the work piece, minimizing the accumulation of error between any particular pair of segments into which the work piece is divided. Additionally, a spanner disc is provided for allowing additional angular movement of the work piece within a secondary angular increment on either side of positions achieved by means of the aforesaid angular increments. This apparatus and method can be employed in any application requiring precision indexed rotational position for any purpose.

    摘要翻译： 一种用于将工件旋转移动和定位的装置和方法，例如用于将工件分成预定数量的相等的段。 该运动通过在给定的角运动增量上重复地角度地移动工件来实现。 通过将多个圆板中的每一个的角位移相加来建立角摆动增量，每个平板分成不同数量的相等的段。 通过适当选择板分割的段数和每个板被移位的段的数量，角度增量可以以非常高的精度建立。 角度增量可以大于工件被划分到的相邻预定段之间的距离。 这允许分配围绕工件的整个周边的工件的每次移动确定的角度增量的误差，从而最小化工件分割成的任何特定的一对段之间的误差累积。 此外，提供了一种扳手盘，用于允许工件在通过上述角度增量实现的位置的任一侧上的次级角度增量内的额外的角度运动。 该装置和方法可用于任何需要精密分度旋转位置的应用中。
