    • The machine tool collet (10) has a plurality of gripping jaws (12) held in a longitudinal and angularly spaced relation about a longitudinal centerline axis (14) through the collet (10). The gripping jaws (12) have an inner face (16) parallel to the centerline axis (14) and the plurality of jaws (12) define an inner diameter opening (18) through the collet (10) for receiving a tool shank (20). Resilient material (28) is disposed between the gripping jaws (12) for holding the plurality of jaws (12) in the desired spaced relation. The radially inward directed stop (30) is defined within the opening (18) of the collet (10). The stop (30) is disposed so as to contact the rear face (22) of a tool shank (20) inserted into the collet (10) thereby preventing rearward axial movement of the tool shank (20) within the collet (10).
    • 机床夹头(10)具有多个夹持爪(12),该夹持爪围绕穿过夹头(10)的纵向中心线轴线(14)以纵向和角度间隔关系保持。 夹爪(12)具有平行于中心轴线(14)的内表面(16),并且多个夹爪(12)限定穿过夹头(10)的内径开口(18),用于接收工具柄(20 )。 弹性材料(28)设置在夹爪(12)之间,用于将多个夹爪(12)保持在期望的间隔关系中。 径向向内指向的止动件(30)被限定在夹头(10)的开口(18)内。 止动件30布置成接触插入夹头10中的工具柄20的后表面22,从而防止工具柄20在夹头10内向后轴向移动。
