摘要： In a first embodiment thereof, the locking means comprises an axially-translatable bolt slidably disposed within a cylinder. The cylinder has an axially-extended slot formed therein, and a pin fixed in the bolt projects therefrom, through the slot, to engage a camming slot formed in a sleeve which envelops the cylinder. A hollow cap-actuator envelops the camming-slotted sleeve, and a drive rib formed in the cap-actuator engages an axial separation in the sleeve to cause (a) the sleeve to rotate, when the cap-actuator is turned, (b) to cause the pin to travel along the camming slot, and (c) to effect extension and retraction of the bolt.

摘要： In the embodiment shown, the chuck comprises a hub rotatably journalled in a jaw carrier, and the latter rotatably journalled in a body. The carrier pivotably mounts a plurality of jaws having camming surfaces, and drive pins upstanding from the hub and the body slidably engage the camming surfaces to move the jaws outwardly, to engage the inner surface of a workpiece, or inwardly, to engage the outer surface of the workpiece. A screw carried in the jaw carrier is movable into the hub, to lock the hub and jaw carrier together, and movable into the body, to lock the body and the jaw carrier together. In the prior circumstance, the drive pins of the body are operative to move the jaws inwardly or outwardly; in the latter circumstance, the pins of the hub are operative to move the jaws as noted above. The jaws have a first plurality of camming surfaces for operative engagement with the drive pins in the body, and a second plurality of camming surfaces for operative engagement with the drive pins in the hub.
摘要翻译： 在所示的实施例中，卡盘包括可旋转地轴颈安装在颚板载体中的轮毂，后者可旋转地支承在主体中。 托架枢转地安装具有凸轮表面的多个钳口，并且从轮毂直立的驱动销和主体可滑动地接合凸轮表面以向外移动夹爪，以接合工件的内表面或向内接合外表面 的工件。 承载在颚托架中的螺钉可移动到毂中，以将轮毂和颚骨承载器锁定在一起，并且可移动到主体中，以将身体和颚骨承载器锁定在一起。 在先前情况下，主体的驱动销可操作以向内或向外移动夹爪; 在后一种情况下，如上所述，轮毂的销可操作以移动夹爪。 夹爪具有第一多个凸轮表面，用于与主体中的驱动销操作接合，以及第二多个凸轮表面，用于与轮毂中的驱动销有效接合。
