A part fixturing system for securing a workpiece includes an expanding clamping device and a work holding device. The expanding clamping device includes a clamp base portion, first and second traversing wedge blocks, an actuation screw, and a clamp plate portion. The clamp base portion comprises a longitudinal recess, and the traversing wedge blocks are located inside the longitudinal recess, each block including an inclined contact surface and a threaded aperture. The actuation screw passes through the longitudinal recess of the clamp base portion and the threaded apertures of the traversing wedge blocks. The clamp plate portion comprises first and second declined contact surfaces. The work holding device comprises first and second support columns that define a longitudinal loading envelope. The expanding clamping device is positioned inside the longitudinal loading envelope of the work holding device and couples the workpiece to the first and second support columns.

1. A part fixturing system for securing a workpiece, the part fixturing system comprising an expanding clamping device and a work holding device, wherein: the expanding clamping device comprises a clamp base portion, a first and a second traversing wedge blocks, an actuation screw, and a clamp plate portion;the clamp base portion comprises a longitudinal recess;the first and the second traversing wedge blocks are located inside the longitudinal recess, each comprising an inclined contact surface and a threaded aperture;the actuation screw passes through the longitudinal recess of the clamp base portion and the threaded apertures of the traversing wedge blocks;the clamp plate portion comprises a first declined contact surface and a second declined contact surface;the work holding device comprises a first support column and a second support column that define a longitudinal loading envelope;the expanding clamping device is positioned inside the longitudinal loading envelope of the work holding device; andthe expanding clamping device couples the workpiece to the first support column and the second support column. 2. The part fixturing system of claim 1, wherein the clamp plate portion travels a clamp expansion dimension as the expanding clamping device expands between a collapsed position and a deployed position. 3. The part fixturing system of claim 2, wherein the clamp plate portion further comprises a skirt extending towards the clamp base portion. 4. The part fixturing system of claim 3, wherein the skirt overlaps the clamp base portion when the expanding clamping device is in the deployed position. 5. The part fixturing system of claim 1, wherein the expanding clamping device further comprises a retention mechanism adapted to limit a separation distance between the clamp base portion and the clamp plate portion. 6. The part fixturing system of claim 5, wherein the retention mechanism comprises a tension spring. 7. The part fixturing system of claim 5, wherein the retention mechanism comprises an interlocking interface between the inclined contact surfaces and the declined contact surfaces. 8. The part fixturing system of claim 1, wherein the clamp base portion further comprises a first and a second longitudinal key portion extending from opposite sides of the clamp base portion. 9. The part fixturing system of claim 1, wherein the clamp base portion further comprises a machining datum surface located on a side opposite the clamp plate portion. 10. A part fixturing system for securing a workpiece, the part fixturing system comprising a work holding device and an expanding clamping device, wherein: the work holding device comprises a first support column and a second support column that define a longitudinal loading envelope;the expanding clamping device comprises a clamp base portion and a clamp plate portion that travels away from the clamp base portion;the expanding clamping device further comprises an opening mechanism adapted to control a separation distance between the clamp base portion and the clamp plate portion;the opening mechanism comprises a first and a second traversing wedge block, each comprising an inclined contact surface and a threaded aperture, an actuation screw secured to the clamp base portion and passing through the threaded apertures of the traversing wedge blocks, and first and second declined contact surfaces coupled to the clamp plate portion;the expanding clamping device is positioned inside the longitudinal loading envelope of the work holding device; andthe expanding clamping device couples the workpiece to the first support column and the second support column. 11. The part fixturing system of claim 10, wherein: the work holding device further comprises a plurality of longitudinal channels extending along inside faces of the first and the second support columns; andthe expanding clamping device further comprises a first and a second longitudinal key portions extending from the clamp base portion; andthe first and the second longitudinal key portions are located within the longitudinal channels. 12. The part fixturing system of claim 11, wherein the clamp base portion further comprises a machining datum surface located opposite the clamp plate portion. 13. The part fixturing system of claim 10, wherein the expanding clamping device further comprises a retention mechanism adapted to limit a separation distance between the clamp base portion and the clamp plate portion.
