    摘要： The invention relates to a clamping chuck. The clamping parts of the jaws are connected to support pieces sliding radially inside the body by means of bolts sliding axially inside these support pieces and provided with teeth.An axially sliding operating ring causes the jaws to clamp by acting on the support pieces by means of levers for example. The bolts are operated by actuating members.To avoid undesired clamping when the clamping parts are disassembled or adjusted, means lock the operating ring when an actuating member is in the position corresponding to retraction of the bolt, preferably before this retraction can be performed.

    摘要翻译： 本发明涉及夹紧卡盘。 夹爪的夹紧部分通过在这些支撑件内轴向滑动并具有齿的螺栓连接到在主体内径向滑动的支撑件。 轴向滑动的操作环通过例如通过杠杆作用在支撑件上而使钳口夹紧。 螺栓由致动构件操作。 为了避免夹紧部件被拆卸或调节时的不期望的夹紧，当操作构件处于与螺栓的缩回相对应的位置时，优选地在该退回可以执行之前，意味着锁定操作环。

    摘要： A chuck having bell crank driven cylindrical master jaws paired with associated workpiece clamping jaws. Each clamping jaw is securely and safely locked to its master jaw and released therefrom by a clamping plate which is disposed in a radial, Tshaped slot in the clamping jaw. The plate has legs extending rearwardly into a radial passage in the master jaw engaging therein a radially disposed camming pin which is actuable to draw the clamping jaw into locked or released position with the master jaw. The clamping jaw, in its released position, is movable radially with respect to the master jaw, for adjustment or removal by sliding movement on the clamping plate. A locking pin is provided to lock each master jaw against radial movement to machine or bore the clamping jaws. A cylindrical sleeve seals the chuck against contaminating particles.

    摘要翻译： 具有曲柄驱动的圆柱形主爪的卡盘与相关联的工件夹紧爪配对。 每个夹爪均牢固而安全地锁定在其主钳上，并通过夹紧板将其夹紧，该夹板设置在夹钳中的径向T形槽中。 该板具有向后延伸到主钳中的径向通道中的腿部，其中啮合有径向设置的凸轮销，该凸轮销可致动以将夹钳牵引到主夹爪的锁定或释放位置。 夹紧钳位于其释放位置，可相对于主钳口径向移动，以通过夹紧板上的滑动运动进行调节或移除。 提供锁定销以锁定每个主夹爪以防止径向运动以加工或夹持夹爪。 圆柱形套筒将卡盘与污染颗粒密封。

    摘要： A chuck comprises radially slidable work-gripping jaws with racks, radially movable sliders with racks engageable with the racks of the jaws, and an axially movable slider-actuating means for radially moving the sliders in unison. Spring means are provided which urge the racks of both the sliders and jaws out of engagement, and a locking or restraining device is provided to force the racks of the sliders and jaws into engagement against the force of the spring means to make the connection between the sliders and jaws. When the locking or restraining device is unlocked, the connection is broken to allow the jaws to be radially moved independently of the sliders for radial adjustment.
