Claim 13:
14. A modular workpiece holding system comprising:
a top portion of a baseplate member disposed on a fixture base and arranged to have a least one wedge pair, each of wedge pairs of the at least one wedge pair arranged to have two or more parallel rows of the at least one wedge pair in each row, each of the wedge pair having an opposingly facing fixed wedge assembly and dynamic wedge assembly;
at least one fixed dynamic wedge assembly that is substantially bilaterally symmetrical with an outwardly facing first wedge face and an oppositely and outwardly facing second wedge face, the wedge faces adapted to each abut a different workpiece member;
each of the dynamic wedge assembly operationally coupled to at least one spring and piston assembly, at least one spring member of each of the spring and piston assembly adapted to draw each of the dynamic wedge assembly axially towards the baseplate member wherein each of the dynamic wedge assembly, when the workpiece holding system is in a resting state, imparts a transverse force onto each of the workpiece member, pressing each of the workpiece member against each of the fixed wedge assembly, securing each of the workpiece to the workpiece holding system;
each of the spring and piston assembly adapted to release each of the dynamic wedge assembly and each of the workpiece member when the workpiece holding system is in an active state, the active state rendered by at least one of a gas and/or hydraulic fluid delivered by way of at least one port within the fixture base, the at least one of a gas and/or hydraulic fluid adapted to at least partly fill a respective spring and piston assembly cavity, pushing, therefore, by way of a piston member of each of the spring and piston assembly, each of the dynamic wedge assembly axially outward from the baseplate; and
the at least one of a gas and/or hydraulic fluid, when discharged from each of the respective spring and piston assembly cavity by way of the at least one port within the fixture base, adapted to reduce outward axial force imparted on each of the dynamic wedge assembly whereupon each of the spring member is adapted to re-impart an inward axial force and, therefore, the traverse force of the resting state of each of the dynamic wedge assembly onto at least one of the same workpiece and a different workpiece; wherein a shape of each of the dynamic wedge assembly is adjustable.
