Abstract: A portable tool for use in axially cutting and squaring ends of tubes includes a main tool body (5) within which is rotatably mounted a tool shaft (49) having a cutting tool (44) attached at one end thereof, a tube receiving and clamping unit (14) for retaining an end portion of a tube (165) to be worked upon, a mechanism (18) for shifting the tool shaft (49) relative to the main tool body (5) so that the cutting tool (44) can progressively engage the end portion of the tube (165) and a power drive unit (77, 73, 83) for rotating the tool shaft. The tube receiving and clamping unit (14) is provided with a plurality of circumferentially spaced ports which provides viewing access to a cutting zone, enables adjustments to or changing of the cutting tool and permits chips cut from the tube to be readily removed from within the tool. The shifting mechanism (18) includes a camming arrangement (19, 180, 188, 198, 199) that ensures smooth shifting of the tool shaft (49) and which is designed to minimize the ingress of foreign matter into the tool.

Abstract: A quick setting and release actuator (10) for cooperating with an axially movable chuck for holding a tubular workpiece (24) in fixed position includes an anchor member (12) that is fixed relative to a housing of a machine tool (20) and a thrust member (42) carried by a pivotally mounted carrier member (38) that pivots towards and away from the anchor member (12) to drive the thrust member (42) into engagement with the end wall (44) of a multi-segment collet (26) to cause the collet (26) to ride along its segment bearing surfaces (30) to engage the periphery of the workpiece (24) to be retained in the machine tool (20). Thrust member (42) may be pivotally mounted by a pivot connection (48) on the carrier (38) so that the thrust member (42) will align itself with the end wall (44) of the collet (26) even when the carrier (38) is not precisely parallel with the collet end wall (44).

Abstract: The present invention relates to a clamping device for clamping a mandrel (28) to an elbow or pipe (18) as well as to a torque-reacting device between a power unit housing (14) and the mandrel. The torque reacting device has a pair of torque reacting keys (42) mounted in a non-rotatable portion of the power unit housing (14), each of the keys having an end portion with converging opposite sides (42a, 42b). The end portions of the torque reacting keys extend into correspondingly shaped, axially extending grooves (56) formed in opposite sides of the mandrel. The opposite sides (56a, 56b) of the grooves are outwardly diverging and define an included angle approximately equal to the angle between the converging sides of the torque reacting keys. Adjusting screws (48) are provided for each of the torque reacting keys. The clamping device has a plurality of clamping pins (62), each pin having a generally cylindrical shape with a hemispherical end portion defining a plurality of concentric ridges (64). An axially moveable actuating member (72) bears on a second end of the centering pins such that movement of the member along the longitudinal axis of the mandrel urges each of the centering pins into contact with the pipe surfaces.

Abstract: An adjustable roller bearing assembly (48) adapted for use in a machine tool includes an elongated support bolt (102) that rotatably supports a radially extending roller bearing (126), and a bushing (66) adapted to be positioned within a bore (53) of a support member and to which the bolt member can be threadably secured. The bushing (66) includes an outer cylindrical portion (80) adapted to be snugly received within a bore of a support member and a cylindrical through hole through which the bolt extends. The outer cylindrical surface of the bushing (66) is eccentric with respect to a central longitudinal axis of the bushing so that the roller bearing (126) and its associated support bolt (102) can be radially adjusted relative to the support member by rotation of the bushing within the bore. The bushing is a one piece integrated sleeve, flange and threaded connector so that only the support bolt and bushing are needed to both clamp the bearing on the support and radially adjust the bearing position relative to the support.

Abstract: A mandrel assembly (10) for use in a portable lathe apparatus for machining the end face of a hollow workpiece (12). The mandrel supports an orbiting cutting tool (18) which machines the end face (14) and defines a cutting plane. The angle of the longitudinal axis (40) of the mandrel and, consequently the cutting plane which is perpendicular thereto, is angularly adjustable with respect to the central axis of the workpiece. This enables the formation of a miter cut on the end of the workpiece. Complimentary hemispherical surfaces (Fig. 3 (70, 64)) having common centers located at the juncture of the cutting plane and the central axis of the workpiece allow the mandrel to be angularly adjusted in any direction.

Abstract: A portable tube end preparation tool includes a right angle drive motor (44) for rotating the cutter head (16) and a right angle cutter feed nut drive shaft (78), both motor and feed nut drive shaft capable of being positioned in the same general plane to provide a narrow and short tool profile for enabling the tool to be used in very confined areas. The drive motor and feed nut drive system are mounted in separate sub-assemblies for enabling simple repair and inspection of the tool without complete or substantial disassembly of the tool, and to permit the feed nut drive to be rotated to different radial positions.

Abstract: Un outil rotatif d'alésage et d'élargissement comprend un corps central (28), une bride proximale de montage (30) et une extrémité distale (36), des plats longitudinaux (44) et des cannelures longitudinales droites (40) situées entre les plats. Les plats dépassent l'extrémité distale du corps tranchant et sont munis de bords tranchants (64) d'alésage radial tournés en avant (par rapport à la direction de coupe), sur l'extrémité distale des plats, et de bords tranchants radiaux d'élargissement (68), dans des parties radialement décalées des plats. La section transversale des plats est généralement trapézoïdale, et un alésage central (56) s'étend à travers le corps central pour loger un mandrin qui porte l'outil tranchant et sa tête d'avance pendant que l'outil est utilisé pour réaliser une opération d'alésage et d'élargissement.
