摘要： A chuck of the type having a body with a plunger that moves axially and is operably connected with wedges that move the jaws radially in response to movement of the plunger. The body is formed with guide surfaces, which maintain contact with the plunger at all times, and also with bearing surfaces which support peripheral surfaces of the wedges.

摘要： Three gripping jaws are slidably engaged in respective radial guide grooves in the front face of an annular jaw carrier for holding work to be machined. Each gripping jaw has a wedge integrally projecting rearwardly therefrom. The wedge is of T-shaped cross section, including a web extending radially of the jaw carrier and a flange at the inner end of the web. Slidably mounted in the jaw carrier for axial movement therein, a plunger has undercut wedge grooves for slidably receiving the flanges and parts of the webs of the respective wedges, causing the radial motion of the gripping jaws by a wedging action upon axial motion of the plunger. A pair of opposed overhanging portions formed by each undercut wedge groove in the plunger are caught between the jaw carrier and the flange of one of the wedges. Thus, in spite of the unavoidable centrifugal displacement of the gripping jaws during the high-speed rotation of the chuck, the overhanging portions of the plunger are subject to no significant bending stresses, being held against the jaw carrier, and so are protected from rupture or strain.
摘要翻译：三个夹爪可滑动地接合在环形夹爪载体的前表面的相应的径向引导槽中，用于保持待加工的工件。每个夹爪具有从其向后一体地突出的楔形物。该楔形件为T形横截面，包括沿着颚式承载件径向延伸的腹板和位于腹板内端的凸缘。柱塞具有底切楔形槽，用于可滑动地接收相应楔形件的凸缘和腹板的部分，从而通过在柱塞的轴向运动时的楔形作用使夹紧爪的径向运动。由柱塞中的每个底切楔形槽形成的一对相对的悬垂部分夹在楔形载体和其中一个楔形物的凸缘之间。因此，尽管在卡盘的高速旋转期间夹持爪不可避免地离心排出，但是柱塞的伸出部分没有受到明显的弯曲应力的影响，并被保持抵靠在卡爪载体上，并且因此被保护以免破裂或应变。

摘要： A chuck body is made up of axially movable plungers and jaws, in which the jaw has a master jaw body obliquely arranged with respect to an axis of the chuck body, the jaw also has a front face of the master jaw body and a rear end face of a master jaw head for restricting a position of the jaw with respect to the chuck body, a plunger receives a bushing which acts as a wedge means cooperating with the master jaw body, a driver at a rear end of the master jaw body being restricted in a backward movement within a range of a gap δ, and a wedge having a structure of canceling a moment applied to the jaw as a result of clamping, the driver providing a reactant force to the master jaw body for canceling a drawing force applied to a plunger.

摘要： A power cylinder for operating a chuck for a machine tool has a rotary cylinder casing, a pair of check valves for confining a pressure fluid in an operating chamber, accumulators for absorbing impacts of the pressure fluid, and detecting means for detecting the fluid pressure in the operating chamber. The power cylinder can be rotated in a state wherein the feeding and discharging of the pressure fluid is stopped.
