  • Patent number: 11826867
    Abstract: The present invention provides certain additional improvements for such mechanical-type multi-axis machine tools. These improvements include: (1) permitting the spindles to be rotated about their respective axes relative to the member independently of one another, (2) providing a low-cost, and yet highly-effective, sensor apparatus for determining the angular position of the member relative to the frame without the use of an expensive encoder or the like, (3) mounting the rotatable member more precisely relative to the frame, and (4) providing a zero-backlash tool slide on the frame for imparting an action to a workpiece.

  • Patent number: 9669466
    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.

  • Patent number: 7930956
    Abstract: An improved Davenport® multi-spindle automatic screw machine has a tool arm (14) mounted on a shaft (41) for rotational movement relative to a revolving head cap (13). A needle bearing (42, 42) is operatively arranged between the shaft and the revolving head cap. The bearing is radially loaded as said bearing is installed and that the individual needles of same remain elastically deformed by the radial load immediately after said bearing has been installed. The shaft has a hardened surface (52) that is engaged by the needles. The diameter of the shaft hardened surface portion is greater than the diameters of the adjacent shaft portions. Annular recesses (51, 53) extend into the shaft at either end of the hardened portion. These recesses have frusto-conical surfaces (55) that act as ramps to guide insertion of the press-fittable needle bearing into the space between the shaft and the head cap.

  • Patent number: 7402927
    Abstract: The present invention provides an improvement for use in a machine tool having a spindle (51) mounted in a body opening (30) for axial and rotative movement relative to a body (31). The improvement includes a bearing assembly (25) that permits spindles (S1, S2, S3, . . . ) to be quickly exchanged while obviating the need to recenter a replacement spindle with respect to the opening after the original spindle has been initially center therein. The improved bearing assembly (25) broadly includes: a ferrous tubular sleeve (29) mounted in the body opening, the sleeve having an outer surface (40) arranged to face toward a portion (31) of the body that surrounds the opening and having an inner surface (36, 39) arranged to face toward a penetrant portion of the spindle; and a tubular bearing (46) arranged within the sleeve, the tubular bearing having an outer surface (51) arranged to face the sleeve inner surface and having an inner surface (50) arranged to face the spindle penetrant portion.

  • Patent number: 6748779
    Abstract: A tangential rolling attachment (20) for a machine tool, broadly includes a body (21); a pair of arms (22L, 22R) having their proximal marginal end portions (23L, 23R) pivotally mounted on the body and having distal marginal end portions (24L, 24R). The arms are biased to move in opposite angular directions such that the distal marginal end portions thereof will be urged to move away from one another. A roll (28L, 28R) is mounted on the distal marginal end portion of each arm for imparting an action to a workpiece when the attachment is moved to tangentially engage the workpiece. A wedge (29) is mounted on the body for movement relative thereto in a direction parallel to the longitudinal axis of the workpiece. An actuator (30) mounted on the body for selectively moving the wedge relative to the body to vary the spacing between the axes of the rolls. The improved rolling head may also incorporate a quick-release mechanism (33L, 33R) for mounting a roll on the arm of the machine tool attachment.
