    • An assembly (10) for holding a cylindrical workpiece (12) for grinding. A support frame (11) includes a support arm (17) to initially hold the workpiece, a tailstock (20) mounted on the support frame to engage the proximal end (13) of the workpiece, and a collet assembly (30) configured to receive the distal end (14) of the workpiece. The collet assembly includes a housing (31) having an open proximal end (33), an open distal end (34), and an internal channel (32). The internal channel extends from the open proximal end to the open distal end to receive spindle (40). The collet is resiliently biased to open when advanced in the proximal direction, and so the housing urges the collet closed when the collet is retracted. A spring (35) between the housing and the spindle resiliently urges the spindle in the distal direction.
    • 一种用于保持用于研磨的圆柱形工件(12)的组件(10)。 支撑框架(11)包括支撑臂(17),以初始地保持工件,安装在支撑框架上以与工件的近端(13)接合的尾座(20)和夹头组件(30) 接收工件的远端(14)。 夹头组件包括具有敞开的近端(33),敞开的远端(34)和内部通道(32)的壳体(31)。 内部通道从开放的近端延伸到开放的远端以接收主轴(40)。 当在近端方向前进时,夹头被弹性地偏压打开,因此当夹头缩回时壳体促使夹头关闭。 外壳和主轴之间的弹簧(35)沿远端方向弹性地推动主轴。

    • PROBLEM TO BE SOLVED: To further facilitate operation for gripping and tightening, and improve sureness and reliability of gripping and tightening in a clamp head driven by a tightening release piston (5) by being placed in a piston chamber (3) in a chuck trunk body (2) and formed of a tightening driving head (4) for opening and closing a collet chuck (9) and a tightening spring (7) disposed in a spring receiving recess part (6). SOLUTION: A spring (15) is provided between a closing stop cover head (17) and the tightening driving head (4) or a constituent member connected to the head. The closing stop cover head (17) retains a plurality of collet jaws (10) such that they retain the opened position and opened posture radially spaced apart from one another at a distal end position when a split type collet chuck (9) is in the position and posture where tightening is released.

    • 要解决的问题:为了进一步促进夹紧和紧固的操作,并且通过将活塞室(3)放置在活塞室(3)中来提高由紧固释放活塞(5)驱动的夹头中的夹紧和紧固的可靠性和可靠性 卡盘主体(2),其由用于打开和关闭夹头卡盘(9)的紧固驱动头(4)和设置在弹簧容纳凹部(6)中的紧固弹簧(7)形成。 解决方案:弹簧(15)设置在闭合止挡盖头部(17)和紧固驱动头部(4)之间或连接到头部的构件上。 闭合止挡盖头部(17)保持多个夹爪(10),使得当分体式夹头卡盘(9)处于所述夹头夹头(9)中时,它们保持打开位置和开口姿态在远端位置处彼此径向间隔开 释放紧固的位置和姿势。 版权所有(C)2010,JPO&INPIT
