    摘要: The invention is directed to a chuck for grasping a tool such as a drill bit or the like and adapted to be tightened with the aid of a chuck key. The chuck includes a hollow body defining a longitudinal axis and having a front end for receiving the tool therein. A plurality of elongated jaws are movably mounted in the hollow body. A sleeve is rotatably mounted on the body and threadably engages the jaws to move the jaws in the body to clamp and release the tool whereby substantial radial forces are transmitted to the body by the jaws when the jaws are tightened on the tool. The sleeve extends in the direction of the longitudinal axis of the hollow body to surround the hollow body at the region of the jaws for supporting the body against the radial forces. A gear is provided for coacting with the chuck key to actuate the sleeve to move the jaws for tightening the jaws on the tool.

    摘要: Core sampling drill head having powered drill chuck with jaws to grip drill rod. Head has thrust member movable by chuck actuating means between jaws retracted and jaws extended position, and precompressed chuck springs cooperating with thrust member and drill chuck so as to be movable with thrust member. Thrust member is located by releasable locking means in desired position, which means also relieve drill bearings of reaction from chuck springs. When thrust member is in jaws retracted position, chuck springs are precompressed by tension means and relatively large diameter tools can pass drill chuck. When thrust member is in jaws extended position, chuck springs cooperate with chuck, are further compressed and extend jaws to grip rod, and tension means are relieved of load from chuck springs. By precompressing and moving springs by themselves, worn drill rods can be accommodated in relatively short drill head without loss of grip. Also, with hydraulically controlled chuck actuating means, when chuck jaws are gripping rod loss of hydraulic fluid pressure does not result in loss of grip on rod as chuck springs are independent of fluid pressure.

    摘要翻译: 核心采样钻头,具有动力钻夹头,夹具夹持钻杆。 头部具有推动构件,其可通过卡爪致动装置在夹爪缩回和延伸位置之间移动,并且预压缩卡盘弹簧与推动构件和钻夹头配合,以便与推动构件一起移动。 推力构件通过可释放的锁定装置位于所需位置,这意味着还释放了卡盘弹簧的钻孔轴承的反作用力。 当推力构件处于夹爪缩回位置时,卡盘弹簧由张力装置预压缩,相对较大直径的工具可以通过钻夹头。 当推力构件处于夹爪延伸位置时,卡盘弹簧与卡盘配合,进一步压缩并延伸夹爪以夹紧杆,拉伸装置从卡盘弹簧释放负载。 通过自己预先压缩和移动弹簧,磨损的钻杆可以容纳在相对较短的钻头中,而不会失去抓地力。 而且,通过液压控制的卡盘驱动装置,当卡盘爪被夹紧时,液压流体压力的损失不会导致卡片弹簧与流体压力无关,因此在杆上不会被夹持。
