    摘要: A centering and self-adjusting chuck for clamping stock includes at least three circumferentially spaced dependent jaws that initially are displaced by being simultaneously radially inwardly driven equal distances under low pressure to center the stock positioned therebetween and further includes at least three other circumferentially spaced independent jaws that are then independently displaced by being radially inwardly driven under low pressure any distance required to have each such independent jaw engage the centered stock, the dependent and independent jaws finally being displaced by being simultaneously radially inwardly driven under higher pressure tightly and uniformly to clamp the stock therebetween for subsequent machining.

    摘要: A drill chuck including a main body part having jaws slidably mounted for converging movement in respective guides. A nut member is rotatably mounted on said main body part and has screwthreaded engagement with the jaws. A cylindrical sleeve is connected at one end to the nut member and at its other end surrounds a portion of a further body part. The further body part, which is provided with mounting means for connecting the chuck to a power tool driving spindle, has an initial degree of co-axial alignment with the main body part but a self-centering action is allowed when drilling.

    摘要: A chuck with key tightening, for a machine such as an electric drilling machine, comprising gripping means for gripping a tool such as jaws, which are guided in a translatory movement in grooves which are inclined with respect to the longitudinal axis of the chuck and which are machined in the chuck body, the chuck being characterized in that it comprises a toothed ring to which a tightening nut is connected, the nut cooperating with the threads of the gripping means, the toothed ring being provided in the region of its teeth with at least one retaining region whose internal diameter is smaller than the external diameter of the tightening nut, at least one component or at least one group of components having the same function, movable with respect to the chuck body, that is to say, the jaws and/or the nut and/or the toothed ring, being of sintered metal. The chuck is particularly advantageous for use on a percussion drilling machine, if desired, because the features of construction prevent its components from becoming disconnected.

    摘要: A collet assembly comprising a spring body member having a cylindrical rear portion and a plurality of spring fingers extending axially therefrom, with an annular bead on the external periphery of the spring fingers near the distal end thereof. Work gripping pads for gripping the exterior of the workpiece are mounted on each of the fingers, and the pads have a groove on the interior thereof for mounting the pads on the beads on the spring fingers. The pads have an exterior surface which forms a frusto-conical cam surface for cooperative engagement with an actuator sleeve, and the pads are free to rock slightly axially on the beads when the collet is opened or closed.Also disclosed are the spring body and the pads for use therewith.
