ABSTRACT:
Two or more plates, each having a matching alignment hole, are precisely aligned and mated together by an aligning and clamping device that includes: (a) a plurality of movable aligning fingers, retraction means for causing the aligning fingers to move into a retracted state where they occupy a first volumetric space sufficiently small to allow the two or more plates to be moved over the retracted fingers so as to have their respective alignment holes surrounding the retracted aligning fingers; (b) expansion means for use after the plates have been moved over the fingers, the expansion means urging the fingers to expand outwardly to occupy a second volumetric space greater than the first volumetric space such that the fingers begin to contact and begin to improve co-alignment between the surrounding alignment holes; and (d) clamping means for use after the alignment holes of the plates have begun to come into improved co-alignment, the clamping means applying a clamping force for clamping the two or more mateable plates together as their respective alignment holes remain in alignment or continue to improve in co-alignment. The aligning and clamping device may further include: (e) fluid removing means for removing at least one of air and other fluids from between the plates as the plates are urged into clamped alignment with one another.
