摘要： 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.

摘要： Each of the two, pivotal, roll supporting arms of a thread rolling attachment has therethrough adjacent the end thereof remote from its pivotal axis a bore in which one end of a cylindrical pattern roll supporting shaft is adjustably secured. The axis of the bore, and hence the axis of the shaft and the pattern roll mounted thereon, are inclined slightly to the pivotal axis of the roll supporting arm, so that the axis or rotation of the pattern roll will be inclined slightly to the axis of rotation of the stock which is to be engaged by the roll. The pattern roll is releasably attached to one end of the support shaft, and is drivingly connected to one end of an internal pin, which is mounted intermediate its ends for rotation in an axial bore which is formed through the support shaft. At its opposite end the pin is releasably connected to a roll gear to which rotation is imparted by the pin upon rotation of the pattern roll. Means are provided for securing the supporting shaft against rotation in its supporting arm, and for adjusting slightly the axis of inclination of the support shaft relative to the axis of the rotating stock.

摘要： The present invention provides an improvement (20) in a Davenport® automatic screw machine having a stationary spindle. The improvement broadly includes a quick-change mechanism (26) associated with the stationary spindle (22). The mechanism includes mating frusto-conical first and second surfaces (28, 31) on the spindle and tool holder, and a multi-lead threaded connection (32) between the tool holder and stationary spindle such that the tool holder may be quickly locked into mating engagement with the stationary spindle by relative rotation therebetween through a short angular distance. The invention may also include an adjustment mechanism (33) that allows the axis (x2-x2) of the tool to be aligned with the axis (x1-x1) of a spaced rotatable spindle. This adjustment mechanism includes a base member (34), an adjustment member (35), and a locking mechanism (37) for selectively holding the adjustment member in the desired position relative to the base member.
