摘要： 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. An axially moveable actuating member bears on an 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 surface.

摘要： An end preparation tool for pipe fittings includes an end preparation tool having a rotary cutting head with shaping bits carried thereon mounted on a base that also carries a universal clamping fixture for pipe fittings having end openings to be machined in preparation for welding. The clamping fixture includes workpiece engaging clamping pads that permit adjustment of the position of the workpiece relative to a pair of opposed clamping plates that normally secure the pipe fitting in place relative to the cutting head of the end preparation tool. The clamping fixture includes adjustment features that enable the fixture to be moved transversely relative to the cutting head, along the rotary axis of the cutting head and about a vertical axis that permits indexing of the clamping fixture relative to the tool cutting head. The workpiece engaging pads are disposed in an array that extends along a square and diagonal pattern of intersecting lines, and along lines perpendicular to the square lines between their intersections. By locating workpiece engaging pads in such a geometric array, virtually all conventional fittings can be accommodated between the clamping pads comprising the clamping fixture using a minimum number of pad elements. Several embodiments of clamping pads are described.

摘要： A tool support and guide assembly for use in repairing boiler tube panels includes a support carriage mountable upon a guide rail that has been previously installed to enable a panel saw tool to be guided along a straight cut line. The support carriage includes a second guide rail conforming in configuration to the first installed guide rail and which extends perpendicularly to the first rail towards the line of cut tube ends. A similar or the same panel saw is mounted on a carriage that is roller guided along the second rail for cutting the membrane between the tubes of the tube panel. A tube end preparation tool is also roller guided along the second guide rail to enable its positioning above each of the cut tube ends so that each tube can be machined (i.e., beveled) in preparation for welding thereto of a replacement tube panel. The perpendicular rails provide a simple guide assembly for accurately locating the saw and the tube end preparation tool. Both rails conform in configuration for receiving identical sets of guide rollers so the panel saw can be interchangeably used with either rail.

摘要： A method for removing a weld crown from a weld joint between first and second work pieces includes steps of positioning a rotary milling tool proximate to the joint and at an offset angle to set a cutting arc relative to the joint. The milling tool is positioned so the cutting arc intersects the weld crown, weld toes, and parent metal on each side of the weld joint. As the milling tool traverses the joint to cut away the weld crown, the milling tool may tilt from side to side to compensate for misalignment between the work pieces along the weld joint. An apparatus for weld crown removal holds a milling tool at an offset angle, and provides a tracking mechanism to permit the milling tool to track misalignment between the work pieces, maintaining the cutting arc in intersection with the weld toes and parent metal along the weld joint.

摘要： A portable single point facing tool (10) includes a drive system (12,18), a rotating base member (14), a feed control mechanism (40) and a tilting cutting head (32) with a cutting tool (30). The tool feed is driven through a gear system (84,86) synchronously with rotation of the base member, a variable throw crank mechanism (82) and a drive rod (83) so that tool feed rate is infinitely variable relative to speed of rotation of the base member. Direction of tool feed can selectively be set at forward, reverse or zero feed by means of a selectively engageable gear train associated with the feed mechanism (40).
