摘要： A jaw assembly for a jaw chuck for holding a workpiece to the spindle of a machine, such as a lathe, includes an intermediate coupling member that engages a master jaw slot formed in a master jaw which is disposed in a radial guide formed in the body of the chuck. A retaining mechanism secures the intermediate coupling member within the master jaw slot. A top jaw is configured to be connectively engaged with the intermediate coupling member by inserting the intermediate coupling member into a top jaw slot. The top jaw is held securely to the intermediate coupling member, and, accordingly, to the master jaw, when the retaining mechanism is tightened. During top jaw change-out the retaining mechanism is released, thereby permitting the top jaw to be disengaged from the intermediate coupling member while still loosely retaining the intermediate coupling member within the master jaw slot. A new top jaw is installed by merely engaging it with the intermediate coupling member and then re-tightening the retaining mechanism.

摘要： A collet chuck assembly includes an annular mount adapted to be attached to a spindle of a turning machine, a tubular collet sleeve disposed internally to the mount including an inner tapered cam surface and adapted to be coupled to an axial moving mechanism of the turning machine, and a tubular collet structure dispose interiorly of the collet sleeve and having a cooperating tapered, outer cam surface. An annular retaining cap has retaining lugs adapted to be engaged with locking flanges of the mount upon engagement of the cap with the mount and rotation of the cap with respect to the mount. The installed cap engages a front end of the collet structure to retain the collet structure within the collet sleeve. A cap anti-rotation mechanism includes an anti-rotation pin carried within the mount for reciprocating axial movement with respect to the mount between extended and retracted positions and a pin actuating mechanism for selectively effecting the reciprocating axial movement. When in the extended position, the anti-rotation pin engages the cap to prevent rotation of the installed cap with respect to the mount. The cap can be rotated with respect to the mount and removed therefrom be moving the anti-rotation pin to the retracted position.

摘要翻译： 夹头卡盘组件包括适于附接到车床的主轴的环形安装座，设置在内部的安装件的管状夹头套筒，其包括内锥形凸轮表面，并适于联接到车床的轴向移动机构， 并且管状夹头结构设置在筒夹套筒的内部并且具有配合的锥形外凸轮表面。 环形保持盖具有固定凸耳，其适于在帽与安装件接合并且相对于安装座旋转盖时与安装件的锁定凸缘接合。 安装的盖接合夹头结构的前端以将夹头结构保持在夹头套筒内。 帽防旋转机构包括承载在安装件内的防旋转销，用于相对于在延伸位置和缩回位置之间的安装件往复运动的轴向运动，以及用于选择性地实现往复轴向运动的销致动机构。 当处于延伸位置时，防旋转销接合盖，以防止安装的盖相对于安装座旋转。 盖可以相对于安装座旋转，并从中移除，从而将防旋转销移动到缩回位置。
