摘要： Tables having nuts are easily assembled and/or replaced on a lead screw from an open side thereof. The lead screw has a large screw near a motor and a small screw remote from the motor. A right-handed screw mating with one of the nuts and a left-handed screw mating with the other of the nuts lie adjacent to each other in the lengthwise direction. A stepped portion of flange coming into an inner ring of a bearing is placed on an end shaft in adjacency to the large screw. The pair of the tables after energization of the motor is controlled to come to a preselected phase in which the tables get closer or nearer each other or come to another preselected phase in which the tables go away from each other.

摘要： An improved chuck for holding an object such as a tool or work piece. The chuck includes circumferentially spaced jaws for grasping an object and a gear mechanism for adjusting the radial position of the jaws to grasp object of varying size. The jaws of the chuck are movable radially outwardly to an open position to permit insertion of an object there between and are adapted to move radially inwardly to an object grasping position. The improvements in the chuck include inclined key threads on the jaws; a rotatable jaw positioning collar around the jaws, including inclined, inwardly extending, circumferentially spaced key threads adapted to cooperatively engage and disengage the key threads on the jaws; a member positioned around the collar for engaging and rotating the collar to engage and disengage the key threads; and, a spring for normally yieldably urging the jaws axially outwardly and radially inwardly when the key threads are disengaged. The jaw positioning collar urges the jaws axially outwardly and radially inwardly to the object grasping position when the collar is rotated to engage the key threads, and permits free axial and radial movement of the jaws to the open position when the collar is rotated to disengage the key threads.

摘要： A drill chuck is disclosed with a pair of jaws and a pair of jaw guiding base plates for centering and holding a drill bit. The chuck comprises a cylindrical housing for the pair of base plates in which the jaws are functionally located. Internal channels and platforms of the above plates guidedly control the movement of the pair of jaws and support a manual adjusting mechanism. The configuration of each of the jaws is such that two rows of triangular spaced apart teeth furnish an adjustable drill receiving opening, or corridor, which is constantly a square for the full range of opening adjustments. Shoulder extensions of the jaws are guidedly located in "V" shaped channels of the base plates. Dowel pins couple an adjusting mechanism to the jaws for guided movement. The adjusting mechanism includes a wedge-shaped body coupled to the dowel pins and a shaft having a left-hand threaded portion threadedly secured to the wedge body and a right-hand threaded portion threadedly retaining a jam nut and an adjusting knob. The nut is frictionally secured within cavities of the base plates. Rotation of the adjusting knob causes the movement of the left and right-hand portions of the shaft through the wedge body and the jam nut for controlling the opening and closing of the jaw opening, or corridor, for centering and holding a drill.

摘要： A high speed hydraulically actuated rotatable chuck for machine tools, permitting the high pressure clamping of elongated work pieces with capacity to be machined simultaneously at opposite ends. Two separate, axially aligned hollow work holding elements are provided, each having capacity to contract diametrically to work clamping condition, and to expand diametrically to work releasing condition. Annular actuators are mounted externally about the work holding elements, with capacity for axial movement relative thereto. A plurality of hydraulically actuated pistons are provided to advance the annular actuators, under a high, uniformly applied working pressure, to contract their work holding elements into work clamping relation. Quick-acting release means retract the actuators, upon deactivation of the pistons, to permit the work holding elements to expand to work releasing condition. The hydraulic system is designed to transmit high pressure fluid from a stationary source to the high speed rotating chuck with a minimum of fluid leakage.
