摘要： A finger includes a pair of overhanging portions that project out laterally from a main body portion. Outer peripheral surfaces of the overhanging portions are made up from five surfaces including upper surfaces, side surfaces, lower surfaces, first end surfaces, and second end surfaces. Crowning is applied to the intersections between these surfaces.

摘要： Chuck comprising a cage in which there are mounted, and guided translationally, multiple jaws converging in the forward direction to grip a tool. The cage is made from at least one flat piece of sheet metal that is cut, folded and/or stamped to form inward-facing grooves for guiding the jaws, and that is closed on itself to form a tubular cage serving to house the jaws and other components, notably jaw driving components.

摘要： Disclosed is the shape of a curvature of two or more pathways for a device having moving parts that cause movement of an object along those pathways, such that the device can locate or hold the object. In the embodiment, an apparatus is described that centers and optionally locks an object at a desired location. The applications for such a device are varied and can range from chucking a workpiece of varying diameters in a lathe, to centering a drone on a landing zone, to medical and scientific devices to capture and center objects to study, to moving atomic level objects using an electromagnetic field. The scope of this disclosure is the mathematics that defines the mirrored curvatures of each curved pathway and the positioning of the curvatures relative to each other, and the relative movement of the mirrored curvatures to cause the desired effect.

摘要： A chuck (10) has a chuck body (12), which is provided with three guide devices (24), on each of which is received a radially movable clamping holder (34) for fixing a workpiece to chuck body (12), the guide device (24) being constructed separately from the chuck body (12). Guide device (24) is integrally joined by a polymer concrete filling (46) to the chuck body (12) for a force transfer between guide device (24) and chuck body (12). There is no need for a particularly precise manufacture of the outer contour of guide device (24) and the recess (20) in chuck body (12), because the polymer concrete (46) is able to compensate tolerances.

摘要： A chuck-claw guide structure includes a guide-space delimiting part that delimits a guide space in communication with an attachment groove, and a regulation part provided on the guide-space delimiting part. The guide-space delimiting part has a contact surface configured to regulate the claw in contact therewith at a position along the attachment groove in a first direction. The regulation part is configured to regulate the claw at a position along the attachment groove in a second direction different from the first direction.

摘要： A chuck for mounting workpiece is disclosed. A chuck for mounting workpiece includes a chuck body; and a base jaw mounted on the chuck body. The chuck body includes an aluminum alloy. The chuck body includes an aluminum alloy having specific gravity smaller than that of alloy steel for machining structural use or carbon steel for machine structure use. Thus, the chuck can be light weight.
