Abstract: The Invention is an improved work holding apparatus and method for a Swiss turning machine. A tube selectably bears upon the apron of a collet. A bell crank selectably bears upon the tube and a conical actuator selectably bears upon the bell crank. Movement of the conical actuator along its longitudinal axis is translated by the bell crank into longitudinal motion of the tube causing the collet to engage or disengage the work piece. The improvement of the Invention is to make the engagement between the conical actuator and the bell crank a rolling engagement. The improvement of the Invention is also to provide a wear member for the tube-engaging portion of the bell crank.

Abstract translation: 本发明是用于瑞士车床的改进的工件保持装置和方法。 管子可选地夹在夹头的围裙上。 钟形曲柄可选择地支撑在管上，并且圆锥形致动器可选择地承载在钟形曲柄上。 锥形致动器沿着其纵向轴线的运动由钟形曲柄转换成管的纵向运动，使得夹头接合或脱开工件。 本发明的改进是使圆锥形致动器和钟形曲柄之间的接合成为滚动接合。 本发明的改进还在于提供一种用于钟形曲柄的管接合部分的磨损构件。
