Abstract: A quick setting and release actuator (10) for cooperating with an axially movable chuck for holding a tubular workpiece (24) in fixed position includes an anchor member (12) that is fixed relative to a housing of a machine tool (20) and a thrust member (42) carried by a pivotally mounted carrier member (38) that pivots towards and away from the anchor member (12) to drive the thrust member (42) into engagement with the end wall (44) of a multi-segment collet (26) to cause the collet (26) to ride along its segment bearing surfaces (30) to engage the periphery of the workpiece (24) to be retained in the machine tool (20). Thrust member (42) may be pivotally mounted by a pivot connection (48) on the carrier (38) so that the thrust member (42) will align itself with the end wall (44) of the collet (26) even when the carrier (38) is not precisely parallel with the collet end wall (44).

Abstract translation: 用于与用于将管状工件（24）保持在固定位置的可轴向移动的卡盘配合的快速设置和释放致动器（10）包括相对于机床（20）的壳体固定的锚定构件（12） 推力构件（42）由可枢转地安装的承载构件（38）承载，所述承载构件（38）朝向和远离所述锚固构件（12）枢转以驱动所述推动构件（42）与多段夹头的端壁（44）接合 （26）以使所述夹头（26）沿其段支承表面（30）骑行以接合所述工件（24）的周边以保持在所述机床（20）中。 推力构件（42）可以通过支架（38）上的枢转连接（48）枢转地安装，使得推力构件（42）将自己对准夹头（26）的端壁（44），即使当载体 （38）不是精确地平行于夹头端壁（44）。
