摘要： An expanding, inner diameter gripping collet assembly for a pick-off spindle. An arbor base is connected to the pick-off spindle and is moveably connected to a moveable arbor. The moveable arbor engages and is driven by the pick-off spindle nose. The moveable arbor has motion-translating cam surfaces on one end that engage corresponding surfaces on one end of an expanding collet. A drawplug having motion-translating cam surfaces that engage corresponding ones on the other end of an expanding collet is inserted through the moveable arbor and secured into the arbor base. The collet assembly also includes an ejector housing, in which an ejector is positioned for sliding movement. A compression spring biases the ejector forwardly.

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.
摘要翻译：用于将工件保持在诸如车床的机器的心轴上的钳口卡盘的钳口组件包括中间联接构件，该中间联接构件与形成在主钳中的主钳口相啮合，主钳口设置在形成于主体中的径向引导件中的卡盘保持机构将中间联接构件固定在主钳口中。顶部颚构造成通过将中间联接构件插入到顶部颚槽中而与中间联接构件连接地接合。顶部钳口牢固地保持在中间联接构件上，并且相应地保持在主钳口上，当保持机构被紧固时。在上颚切换期间，保持机构被释放，从而允许顶颚与中间联接构件分离，同时仍然将中间联接构件保持在主颚槽内。通过仅将其与中间联接构件接合并且然后重新紧固保持机构来安装新的顶部夹爪。

摘要： A collet chuck assembly for an axially fixed collet head. The collet head is fixedly and removably mounted in a threaded bushing to prevent axial motion, and is keyed into place to prevent rotation. A sleeve assembly has cam surfaces adapted to engage the cam surfaces of the collet head to open and close the collet head, and slides between collet head open and collet head closed positions within a spindle adapter body. The sleeve assembly has projections that extend from a rearward portion and pass through appropriately sized passages in the axially-fixed bushing. Motion from a spindle drawbar is transmitted by a drawbar link-up through the projections of the sleeve assembly. Using this arrangement, no physical connection is required between the drawbar link-up and the sleeve assembly. Additionally, no cap assembly is required.
摘要翻译：一种用于轴向固定夹头的夹头卡盘组件。夹头固定地可拆卸地安装在螺纹套管中以防止轴向运动，并被卡入到位以防止旋转。套筒组件具有适于接合夹头的凸轮表面的凸轮表面，以打开和关闭夹头，并且在夹头头部打开和在主轴适配器主体内的夹头之间关闭位置之间滑动。套筒组件具有从后部延伸并穿过轴向固定衬套中适当尺寸的通道的突起。来自主轴牵引杆的运动通过牵引杆连接通过套筒组件的突起传递。使用这种布置，在牵引杆连接和套筒组件之间不需要物理连接。另外，不需要盖组件。
