ABSTRACT:
An alignment device with a radially expandable tube for temporary alignment of a plurality of apertured workpieces in which the precise alignment of associated apertures is required. The radially expandable tube extends from the housing, and contains a plurality of bearings, each associated with at least one radially expandable ring. Each bearing has a tapered surface that engages and radially expands its associated ring upon relative movement of the bearing into the ring. The expansion of the rings applies a radially outwardly directed force on the interior surface of the tube.
