摘要： 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.

摘要： A rigid tool slide support is disposed to be mounted in a screw machine in either of two different operating positions in each of which a tool slide reciprocates on the upper surface of the support to convey a cutting tool to and from the work that is to be machined. Projecting centrally from the bottom surface of the slide is an elongate, dovetail shaped guide which is slidably mounted in a similarly shaped but slightly wider recess in the support. Secured in the recess of the support adjacent one side thereof, and slidably engaged with a confronting side of the dovetail guide of the slide, is an elongate expansion gib having therein an adjusting screw that is rotatably adjustable to expand or contract the length of the gib, thereby to adjust the running clearance between the support and the slide. Mounted on the slide are two coupling pins, one of which is connected to a pivotal slide operating arm when the support is mounted in one of its two different operating positions, and the other of which pins is adjustable into and out of an operating position in which it projects from one side of the slide and into a reciprocable slide operating arm when the support is mounted in the other of its two operating positions,

A plurality of knurl rolls (26, 26, 26) are mounted on the body first part between the front and center plates. An arbor (28) is axially mounted on the body second part, and is biased to move toward the front plate. The end of a rotating workpiece (W) is adapted to be axially inserted through the front plate and moved toward the body second part between the knurl rolls to roll a knurl pattern on the workpiece. The angular relationship between the knurl rolls is continuously maintained at all times.

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.
