摘要： A self-centering, radially reciprocating jaw chuck for machine tools and the like comprising a chuck body member, a plurality of master jaws secured to the body member, each of the master jaws having a pair of circumferentially spaced fixed portions rigidly secured to the body member and a radially reciprocable portion positioned circumferentially between the fixed portions. Resilient means integral with both the fixed portions and the radially reciprocable portion connect these portions, and a work gripping member is secured to each of the radially reciprocating portions. Axially reciprocable means is provided within the body member for radially reciprocating the radially reciprocable portions, and work gripping members attached thereto, whereby flexure of the resilient means provides a self-centering action of the work gripping members with respect to the longitudinal axis of the chuck and the work.
摘要翻译：一种用于机床等的自定心的径向往复式卡爪，其包括卡盘主体部件，固定到主体部件上的多个主卡爪，每个主卡爪具有刚性地固定到主体上的一对周向间隔开的固定部分构件和位于固定部分之间周向的径向往复运动的部分。弹性装置与两个固定部分成一体，并且可径向往复运动的部分连接这些部分，并且工件夹持件固定到每个径向往复运动部分。轴向往复运动的装置设置在主体构件内用于使径向往复运动的部分径向往复运动，以及附接到其上的工作夹持构件，由此弹性装置的挠曲提供了相对于卡盘的纵向轴线的夹紧构件的自定心作用和工作。
