摘要： A workholding apparatus (20) comprising a chuck body (22), first jaw members (26) and second jaw members (50) wherein the second jaw members are shaped to grip a workpiece (56, 64) of a particular geometry. The jaw members are constructed to enable easy, quick and manual replacement of the second jaw members. Each first jaw member (26) includes an outer fixed gripping member (30) and an opposed inner gripping member (32) shaped like a clasp and movable between an open release and a closed gripping position. Clasp (32) is pivotable about a pin (42).

摘要： Bei einem Spannfutter (1) mit radial verstellbaren Grundbacken (4), in deren stirnseitige Verzahnung (6) auswechselbare Aufsatzbacken (11) eingreifen und die mit diesen mittels eines Nutensteines (15) kuppelbar sind, der durch ein Verstellglied (21) mindestens um die Höhe der ineinandergreifenden Verzahnungen (6, 12) verschiebbar ist, ist das Verstellglied (21) durch einen den Schaft (17) des Nutensteines durchgreifenden Spannbolzen (22) gebildet, der über eine kegelförmige Spannfläche (26) an einer verdrehbar gehaltenen Gewindespindel (31) abgestützt ist, derart, daß der Nutenstein (15) durch die bei Verdrehung der Gewindespindel (31) mit Gegenflächen (28, 33) zusammenwirkenden Spannflächen (24, 26) des Spannbolzens (22) in Achsrichtung seines Schaftes (17) verstellbar ist.
Durch diese Ausgestaltung ist es möglich, Aufsatzspannbacken (11) in sehr kurzer Zeit mit Grundbacken (4) zu koppeln oder diese Verbindung zu lösen, außerdem ist auch eine äußerst hohe Stabilität der Grundbacken-Aufsatzbacken-Einheit gegeben, so daß auch sehr hohe Kräfte übertragen werden können.摘要翻译： 在具有可径向调节的底爪（4）的卡盘（1）中，在其中可更换的辅助夹爪（11）接合并且可通过滑动块（11）联接到这些辅助夹爪（11）的正齿系统（6） （15），其可被调节构件（21）移位至少达到所述接合齿系统（6,12）的高度，所述调节构件（21）由夹紧销（22）形成，所述夹紧销（22）穿过所述柄 （17），并且其经由锥形夹紧表面（26）支撑在可旋转地保持的螺纹心轴（31）上，使得滑动块（15）可以在其柄部的轴向方向上被调节（ 17）通过夹紧销（22）的夹紧表面（24,26），当夹紧表面（24,26）在螺纹心轴（31）旋转时与配合表面（28,33）相互作用。 ...这种设计使得辅助夹爪（11）非常快速地连接到基座爪（4）上，或者使得该连接被释放。 另外，底爪/辅助颚单元也具有极高的稳定性，从而能够传递甚至非常高的力。 ...

摘要： A workholding chuck can use actuating members that pivot within a non-split unitary front bearing. The non-split unitary front bearing can include pockets in its central bore that can allow a spherical section of an actuator arm to be inserted into the bearing. The spherical section can include radially recessed areas to facilitate the insertion into the bearing. The jaws can be retained to the actuator arms through the use of a quick-release assembly. The quick-release assembly allows the jaws to easily and quickly be changed to allow the chuck to grasp different workpieces.

摘要： A chuck-claw coupling mechanism includes a coupling member provided in a master jaw, a first resilient member, and an operation unit. The coupling member is movable between a coupling position at which the coupling member is coupled to the claw, and a separation position at which the coupling member is separated from the claw. The first resilient member urges the coupling member toward the coupling position. The operation unit moves the coupling member to the separation position.
