    摘要： The drive mechanism is for use with a rotary tube cutter having an elongate cutter body (44) which is insertable into a tube to be cut, and which has disposed therein a cutting-element carrier (54) and an elongate member (48) which is movable to advance the cutting-element carrier in a cutting direction. The drive mechanism includes a housing (70) having means (76) for rotatably supporting the cutter body (44) at a rear portion thereof, drive means (72) for rotating the cutter body, and cutter-element feed means (74) cooperable with the elongate member (48) and effec­tive, during rotation of the cutter body, to intermittently move the elongate member so as to advance the cutting-element carrier (54) incrementally in said cutting direction at a rate proportional to the rotational speed of the cutter body. The cutter-element feed means (74) also is manually operable (106) to advance the cutting-element carrier (54) to, or to retract it from, its cutting position.

    摘要： Un outil portatif d'usinage d'extrémités de tubes comprend un moteur d'entraînement disposé à angle droit (44) servant à faire tourner la tête du couteau (16) et un arbre d'entraînement d'écrou d'avance du couteau disposé à angle droit (78). Aussi bien le moteur que l'arbre d'entraînement d'écrou d'avance peuvent être positionnés dans le même plan général pour obtenir un profil étroit et court de l'outil permettant d'utiliser celui-ci dans des zones très limitées. Le moteur d'entraînement et le système d'entraînement de l'écrou d'avance sont montés dans des sous-assemblages séparés afin de permettre un contrôle et un entretien aisés de l'outil sans qu'il soit nécessaire de démonter complètement l'outil, et afin de permettre à l'entraînement d'écrou d'avance de tourner dans différentes positions radiales.

    摘要： A tool feeding head ist provided, which is adapted for rapid attachment to and detachment form a machine spindlehead. The head includes a shaft which is joinable to a machine spindle of the spindlehead for coupling rotary driving motion from the spindle to either a cross-feed or feed-out cutting tool, the shaft being provided with a bore. An actuating rod is mounted in the bore for engaging the tool, the actuating rod feeding the tool when the actuating rod is reciprocated within the bore by a rod reciprocating mechanism. A system or device for controllably driving the rod reciprocating mechanism is immovably fixed to the machine spindlehead, the driving system operating the rod reciprocating mechanism to cause the actuating rod to feed the selected tool at a prespecified rate. Structure supporting the shaft and the reciprocating mechanism enables an automatic tool changer to selectively join the shaft to the spindle, and place the rod reciprocating mechanism in operative relationship with the driving system.
