摘要： 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.

摘要： A rotary loader for feeding bars to lathes comprises a stepped rotary drum (11) and supporting guides (13) for sliding of the bars. A flange (16) coaxial and integral with the drum supports peripherally braking surfaces (17) such as pins arranged with a pitch equal to the drum braking pitch. An opposing surface (20) is pushed elastically towards the drum rotation axis to meet the braking surfaces in sequence and supply drum braking and stopping action against its inertial movement.

摘要： A bar feeding device for multi-spindle machine tools includes a rotating drum provided with a plurality of guides for the bars, which longitudinally extend in different angular positions on the outer surface of the drum. Bar pushing members slidingly movable along the guides are connected to a control system comprising a set of peripheral gears circumferentially arranged at one end, and supported to rotate with the drum, coplanarly around a central pinion gear connected to a drive motor. The pinion gear is tangentially arranged in an offset angular position to selectively engage each peripheral gear over a predetermined arch shaped path by rotation of the drum.
