摘要： A clamping module has a retractable drawbar and pivoting expansion members. The expansion members are pivotable from a first position having an effective diameter which is less than the minimum diameter of the workpiece hole through which the drawbar and expansion members are extended and a second position engaging the workpiece so as to transmit an axial force from the drawbar through the expansion members to the workpiece sufficient to secure the workpiece.

摘要： A flexible hydraulic vise that is actuated hydraulically along the entire length of the jaw travel. The vise includes master jaws disposed in a complementary shaped tracks, connected to pistons by pins. Top jaws with spring loaded ball detents are secured to the master jaws by a dove-tail notch connection. Internal passageways allow pressure to be delivered to either side of pairs of the pistons disposed in the bores, allowing the clamping force to be exerted inwardly or outwardly.

摘要： The present invention is directed to a chucking system. The body of the chucking system preferably houses cam plates which may be driven manually by an independent worm shaft, or hydraulically by a piston/gear rack in lieu of a worm shaft. A face plate preferably houses four master jaws. The jaws may be engaged to the cam plates by pins. The jaws may be moved inward and outward preferably by rotation of the cam plates due to the ascending/descending slope of the slots in the cam plates. Each set of two jaws may be driven independently of the other because of the two separate cam plate mechanisms. The top cam plate is preferably held concentrically to the bottom cam plate by a needle bearing. The entire cam plate may “sandwich” pivot on a center tube which may be anchored in the base of the body and the top face plate.

摘要翻译： 本发明涉及一种夹紧系统。 卡盘系统的主体优选地容纳可以由独立的蜗杆轴手动地驱动的凸轮板，或者通过活塞/齿条代替蜗杆轴进行液压的凸轮板。 面板优选地容纳四个主钳口。 夹爪可以通过销接合到凸轮板。 优选地，由于凸轮板中的槽的上升/下降斜率，夹爪可以优选地通过凸轮板的旋转而向内和向外移动。 由于两个分离的凸轮板机构，每组两个夹爪可以彼此独立地驱动。 顶部凸轮板优选地通过滚针轴承同心地保持在底部凸轮板上。 整个凸轮板可以在可以锚固在主体的基部和顶面板中的中心管上“夹紧”枢轴。
