Abstract: A tube squaring tool includes a housing having forward and rearward end areas and a tubular workpiece clamping device located at the forward end area for securing and retaining a tubular workpiece relative to the housing so that the end of the workpiece can be machined by a rotary cutting head carried by the housing and movable towards and away from the end of the workpiece by manipulation of a feed mechanism. The tubular workpiece clamping device includes a pair of saddle members carried within a saddle mounting ring with one of the saddle members being frictionally secured within the mounting ring using a detent mechanism and the other saddle member being movable relative to the mounting ring and the opposing saddle member by a threaded connector that enables clamping of a tubular workpiece between the saddle members when the moveable saddle member is moved in a clamping direction towards the opposed fixed saddle member.

Abstract: A quick setting and release actuator for cooperating with an axially movable chuck for holding a tubular workpiece in fixed position includes an anchor member (12) that is mounted in fixed relationship 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 to drive the thrust member (42) into engagement with the end wall (44) of a multi-segment collet (26) to cause the collet to ride along its segment bearing surfaces (30) in a radial direction to engage the periphery of a 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 will align itself with the end wall (44) of collet (26) even when the carrier is not precisely parallel with the collet end wall.

Abstract: The present invention relates to a clamping device for clamping a mandrel to an elbow or pipe as well as to a torque-reacting device between a power unit housing and the mandrel. The torque reacting device has a pair of torque reacting keys mounted in a non-rotatable portion of the power unit housing, each of the keys having an end portion with converging opposite sides. The end portions of the torque reacting keys extend into correspondingly shaped, axially extending grooves formed in opposite sides of the mandrel. The opposite sides 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 are provided for each of the torque reacting keys. The clamping device has a plurality of clamping pins, each pin having a generally cylindrical shape with a hemispherical end portion defining a plurality of concentric ridges.
