Workpiece holding fixture for machining multiple prismatic parts
A workpiece holding fixture including a base plate having an engagement surface including a travel slot. A first static riser includes a position control member configured to removably couple a workpiece to the first static riser. A second static riser includes a rotation control member and is configured to removably couple the workpiece to the second static riser. A dynamic riser is configured to abut the workpiece by automatic, semi-automatic, or manual movement into secure engagement with the workpiece. The dynamic riser is slidably coupled with the travel slot and is operable between a plurality of positions associated with workpiece variants having different locating features and geometries.
1. A workpiece holding fixture comprising:
a base plate having a travel slot, the travel slot defined by first and second rails;
a first static riser including a position control member configured to removably couple a workpiece to the first static riser;
a second static riser including a rotation control member and configured to removably couple the workpiece to the second static riser; and
a dynamic riser configured to abut the workpiece, the dynamic riser being slidably coupled to the first and second rails and operable between a plurality of positions associated with workpiece variants having different locating features and geometries.
2. The workpiece holding fixture of claim 1 , wherein the dynamic riser is movably coupled to an elevatable stanchion.
3. The workpiece holding fixture of claim 1 , wherein the dynamic riser is movably coupled with a linear motor.
4. The workpiece holding fixture of claim 1 , wherein the dynamic riser is movably coupled with a hydraulic cylinder.
5. The workpiece holding fixture of claim 1 , wherein the dynamic riser is movably coupled with an electromechanical system.
6. The workpiece holding fixture of claim 1 , wherein the dynamic riser is movable along a linear path.
7. The workpiece holding fixture of claim 1 , wherein the dynamic riser is movable along an arcuate path.
8. The workpiece holding fixture of claim 1 , wherein each of the first and second static risers and the dynamic riser include a vertically extendable and rotatable securing clamp.
9. A workpiece holding fixture comprising:
a base plate;
first and second static risers engaged with an engagement surface of the base plate having engagement pins to securely engage a workpiece at predetermined locating positions;
a dynamic riser configured to movably engage the workpiece in a first direction; and
a transition device configured to electronically move the dynamic riser in a second direction along the engagement surface of the base plate.
10. The workpiece holding fixture of claim 9 , wherein the dynamic riser is movably coupled to an elevatable stanchion.
11. The workpiece holding fixture of claim 9 , wherein the dynamic riser is movably coupled with a linear motor.

16. The workpiece holding fixture of claim 15 , wherein each securing clamp is operable between an engaged position and a disengaged position.
17. The workpiece holding fixture of claim 9 , wherein a first powered system moves the dynamic riser in a first direction to engage a workpiece and a second powered system powers the transition device that moves the dynamic riser in a second direction that is substantially perpendicular to the first direction.
18. A method of holding a workpiece for processing comprising:
providing a base plate;
securely engaging first and second static risers to the base plate;
adjusting a dynamic riser into secure engagement with an unprocessed initial workpiece;
engaging the first and second static risers with the unprocessed initial workpiece at predetermined locating positions;
verifying proper engagement of the workpiece; and
processing the unprocessed initial workpiece.
19. The method of claim 18 , further comprising:
translating the dynamic riser over the base plate using one of a hydraulic cylinder and a pneumatic cylinder.
20. The method of claim 19 , further comprising:
disengaging the first and second static risers with the workpiece and the dynamic riser with the workpiece by rotating securing clamps out of engagement with tabs on the workpiece;
engaging the first and second static risers with an unprocessed second workpiece at predetermined locating positions; and
adjusting a dynamic riser into secure engagement with the unprocessed second workpiece.
