Abstract: A rear worm drive shaft (60) for a Davenport® multi-spindle automatic screw machine, comprises: a shaft first part (61) having a portion with a first hardness; a shaft second part (62) having a portion with a second hardness, said second hardness being greater than the first hardness; and a coupling (63) adapted to join the shaft first and second parts in an axially-aligned relation and to prevent relative rotation therebetween. The improved shaft may be changed on a Davenport® screw machine is about one-half hour.

Abstract: The spindle supporting head of a multiple spindle screw machine is intermittently rotated to place its spindles into successively different angular positions about the axis of a spindle drive shaft which extends coaxially into the center of the head. When each spindle is rotatably indexed into a particular angular position, a piece of bar stock is fed through the spindle and projects beyond one end thereof. Each of a plurality of tool slides, which are mounted adjacent the end of the head from which the spindle projects, carries a tool which registers with the stock projecting from an adjacent spindle. The slides are connected to servo motors which are operable by an associated computer to move their tools toward and away from the stock projecting from the associated spindles. Normally the head is secured against rotation by a hirth ring which intermittently is moved from its locking position to release the head so that it can be rotatably indexed. Each spindle is surrounded by a chuck operating sleeve which causes the associated collet chuck to be opened when the spindle approaches a position immediately preceding its desired angular position, and to be closed when the spindle reaches such position.

Abstract translation: 多轴螺旋机的主轴支撑头间歇地旋转，以将其主轴绕轴心驱动轴的轴线连续不同的角度位置，该主轴驱动轴同轴地延伸到头部的中心。 当每个主轴可旋转地分度成特定的角度位置时，一条棒料通过主轴进给并突出超过其一端。 靠近主轴突出的头部端部安装的多个工具滑块中的每一个承载与从相邻主轴突出的坯料对准的工具。 滑块连接到伺服电机，伺服电机可由相关联的计算机操作，以使其工具朝向和远离从相关主轴突出的股票移动。 通常头部通过环形环固定，间隔从其锁定位置移动以释放头部，使得其可旋转地分度。 每个主轴由卡盘操作套筒包围，当主轴接近其所需角度位置之前的位置时，该卡盘操作套筒使相关联的夹头卡盘打开，并且当主轴到达该位置时关闭。

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.

Abstract: An automatic screw machine (20) has a body (22), and a head (21) that is rotatably mounted on the body and that is adapted to be selectively rotated relative to the body between any of a plurality of index positions. The body and head have closely-spaced and facing bearing surfaces (25, 28 and 26, 29), have spindles (23) journalled on the head for rotation relative thereto, and have a source of pressurized lubricant. The improvement broadly includes: at least one body passageway (32) communicating the source with the body bearing surface, the intersection of each body passageway with the body bearing surface defining a body port (33); a head passageway (36) communicating the head bearing surface with the spindle, the intersection of said head passageway with said head bearing surface defining at least one head port (42); and the body and head passageways being so configured and arranged such that lubricant may flow from the source to the spindle only when the head is in the vicinity of the index position such that the body and head ports overlap one another.
