    • A chuck assembly which can chuck thin and brittle workpieces that differ widely in size with high accuracy and reliability without warping them. The chuck assembly includes a tubular chuck body having three first cylinders and a plurality of second cylinders arranged along a circumference in a plane perpendicular to the axis of the chuck body at equal angular intervals. The cylinders have pistons adapted to protrude under oil pressure. The three first cylinders are also arranged at equal angular intervals. The chuck assembly further includes a pressure-biasing means for applying, independently of the oil pressure, pressure to the pistons of the first cylinders against a workpiece, so that the piston are less likely to be retracted by the reaction force from the workpiece. That is, this chuck assembly has a self-centering function.
    • 卡盘组件可以夹紧薄而脆的工件,这些工件尺寸大小不一,精度高,可靠性好,不会翘曲。 卡盘组件包括具有三个第一圆柱体和多个第二圆柱体的管状卡盘体,所述第一圆柱体和多个第二圆柱体以垂直于卡盘体的轴线的平面中的圆周以相等的角度间隔设置。 气缸具有适于在油压下突出的活塞。 三个第一气缸也以相等的角度间隔布置。 卡盘组件还包括一个压力偏置装置,用于独立于油压向第一气缸的活塞施加压力抵靠工件,使得活塞不太可能被来自工件的反作用力缩回。 也就是说,该卡盘组件具有自定心功能。 <图像>

    • PURPOSE: A coupling device is provided to accurately determine the circumferential and axial positions of two members parallel to each other in an axial direction. CONSTITUTION: A coupling device(1) comprises a first member(21) and a second member(22). The first and second members are relatively moved in an axial direction and are connected and separated from each other. Saw teeth rows(31,32) are respectively installed on the surfaces of the first and second members and determine the circumferential positions of the members. When the first and second members are connected, the first and second members are in contact with contact surfaces(33a,34a) of contact parts(33,34) and determine the axial positions of the members.
    • 目的:提供耦合装置以精确地确定在轴向方向上彼此平行的两个构件的周向和轴向位置。 构成:耦合装置(1)包括第一构件(21)和第二构件(22)。 第一和第二构件在轴向方向上相对移动并且彼此连接和分离。 锯齿排(31,32)分别安装在第一和第二构件的表面上,并确定构件的圆周位置。 当第一和第二构件连接时,第一和第二构件与接触部分(33,34)的接触表面(33a,34a)接触并确定构件的轴向位置。
