摘要： A machine tool turret head, more particularly a power operated turret head, is provided with fluid power actuated toggle means for axially clamping the turret head to the machine tool ram or saddle. When a wedge member is withdrawn from a position between the toggle members, the turret head is released from a clamped work position and allowed to slide axially for a limited distance along a turret head stem. Logic circuitry and a resolver are employed to cause a motor and drive train to rotate the turret head and to locate the head via the most expeditious route within the predetermined initial angular tolerance limits of a new work position. The wedge member is then reinserted between the toggle means to move the turret axially back along the stem, and reclamp the turret in its new work position. A lost motion coupler is included in the drive train to allow the turret head to rotate slightly as it moves into its clamped position without damage to the associated drive train or other parts.

摘要翻译： 机床转塔头，更具体地说是一个动力操作的转塔头，设置有用于将转台头轴向夹紧到机床压头或鞍座的流体动力驱动的肘节装置。 当楔形构件从肘节构件之间的位置撤回时，转台头部从夹紧的工作位置释放并允许沿着转台头杆轴向滑动一段有限的距离。 采用逻辑电路和旋转变压器来使电动机和传动系转动转台头部，并通过在新的工作位置的预定初始角度公差极限内的最快捷的路线定位头部。 然后将楔形构件重新插入在肘节装置之间以沿着杆轴向向后移动转台，并将转塔重新放置在其新的工作位置。 传动系中包括一个失速联动器，以便当转塔移动到其夹紧位置时，转塔头稍稍旋转，而不损坏相关联的传动系或其他部件。
