Abstract: An improved spindle assembly for a Davenport® multi-axis screw machine is adapted to adequately hold one-inch round bar-stock in a collet against movement relative thereto attributable to machining operations performed on a cantilevered length of bar-stock held in and extending beyond the collet. The spindle assembly may permit the use of the screw machine on materials thought heretofore to be too difficult to machine on a screw machine. Cam surfaces on the inner spindle and collet may be coated with a low-friction material. A stress-relieving connection between the inner spindle and collet is provided.

Abstract: A gripper for use in combination with a pin has a body having an axially open cavity in which the pin is engageable. Jaws in the cavity are radially displaceable between an inner holding position bearing radially inwardly on and gripping the pin and an outer release position in which the pin can be removed axially from the cavity. An actuating element in the body is engageable with the jaws and shiftable between end positions corresponding to the inner and outer positions of the jaws. An actuator connected to the actuating element can move it from one of the end positions into the other of the end positions. An externally accessible connecting or operating member on the chuck body is connected through an emergency release with the jaws for moving the jaws into the outer release position as the result of connection to or operation of the member.

Abstract: A clamping device for clamping different sizes of cylindrical objects includes a body having a path defined centrally therethrough. The body has a polygonal section which has multiple corners at equal intervals. A clamping portion having outer threads is connected to one end of the polygonal section and a locking collar is threadedly connected to the clamping portion. The clamping portion clamps an object. The body has a room defined therein and the room has a tapered inside so as to accommodate a clamping sleeve which has a clamping hole and a tapered outside which is engaged with the tapered inside of the room. The clamping collar controls the size of the clamping hole of the clamping sleeve to proceed vertical or horizontal machining. The clamping sleeve releases the object by loosing the locking collar.

Abstract: A chuck has a chuck body at least generally centered on a body axis and a collet in the hole and having an external screwthread. A ring axially nondisplaceable in the body has an internal screwthread engaging the screwthread of the collet and external gear teeth. The body is formed with a radially outwardly open cavity seat in which some of the teeth of the ring are exposed. A gear fitted in the seat meshes with the ring teeth and can rotate about a drive axis not parallel to the body axis to rotate the ring about the body axis. According to the invention a sleeve on the chuck extends axially across and covers the seat to retain the gear therein and is formed with a through going aperture through which a tool can fit to engage and rotate the gear.

Abstract: A tool chucking apparatus to hold a machining cutter or tool includes a holding member and a fastening member that are coupled together to form a grip space inside to hold a collet. The collet has a plurality of pawl structures with a plurality of elastic slots formed thereon. When the holding member and the fastening member are coupled, the collet has one end tightly held in the holding member and the other end tightly held in the fastening member. Hence the two ends of the collet contract the elastic slots to tightly grip the cutter or tool. As a result, machining precision improves, safety enhances and the life span of the cutter or tool increases.

Abstract translation: 用于保持加工刀具或工具的工具夹持装置包括联接在一起以在夹持夹具内部形成夹紧空间的保持构件和紧固构件。 夹头具有多个棘爪结构，其上形成有多个弹性槽。 当保持构件和紧固构件联接时，夹头的一端紧固地保持在保持构件中，另一端紧紧地保持在紧固构件中。 因此，夹头的两端收缩弹性槽，以紧紧抓住刀具或工具。 结果，加工精度提高，安全性提高，刀具或工具的使用寿命增加。
