Methods and devices for alignment and joining large components
Methods, apparatus, and devices for fixturing and alignment of parts and panels for assembly into aerospace components, are provided. These methods and devices are designed for joining together several large part segments into a larger complete component.
1 . A panel alignment and assembly apparatus comprising:
a fixturing structure comprising a plurality of support towers and at least one alignment tower wherein the at least one alignment tower comprises a constraint system configured to constrain and align a plurality of panels;
a joining device and the at least one alignment tower disposed within a joining area;
a rail disposed on the fixturing structure at a set height and configured to circumscribe the joining area;
a plurality of carts coupled to the rail and configured to translate along the rail;
a plurality of brackets, wherein each bracket is configured to couple to one of the plurality of panels and a cart, and to align the coupled panel relative to the joining device when the coupled panel hangs from the bracket,
wherein the constraint system comprises a plurality of clamps including at least one upper clamp disposed on an upper portion of the alignment tower and at least one lower clamp disposed on a lower portion of the alignment tower and wherein the at least one upper clamp and the at least one lower clamp are configured to align and secure one of the plurality of panels therebetween.
2 . The apparatus of claim 1 , wherein each of the plurality of brackets is configured to selectively couple to one of the plurality of carts.
3 . The apparatus of claim 1 wherein each of the plurality of brackets is further configured with a mounting point configured to couple with a manipulation device, the manipulation device being configured to manipulate both the coupled bracket and the panel coupled thereto.
4 . The apparatus of claim 1 , wherein the cart couples to the rail via a plurality of wheels, at least one of which is an eccentric wheel configured to position and align the cart relative to the rail.
5 . The apparatus of claim 4 , wherein the rail and the plurality of wheels are configured with complementary geometries that secure the cart to the rail.
6 . The apparatus of claim 1 , wherein each of the plurality of brackets comprises at least one through-hole configured to receive a bolt and couple the bracket to at least one of: one of the plurality of carts and one of the plurality of panels.
7 . The apparatus of claim 1 , wherein the at least one lower clamp is at least two lower clamps and each clamp is configured to translate up and down independently tilting the panel to align the panel.
8 . The apparatus of claim 1 , wherein the rail comprises at least one removable section of rail configured to articulate from a first position to a second position.
9 . The apparatus of claim 1 wherein each of the carts is further configured to translate radially relative to the joining area.
10 . The apparatus of claim 6 , further comprising a retention element configured to secure the bolt.
11 . The apparatus of claim 1 , wherein the at least one upper clamp is in connection with at least one upper roller, wherein the at least one upper roller is configured to translate up and down the constraint system.
12 . The apparatus of claim 1 , wherein the at least one lower clamp is in connection with at least one lower roller, wherein the at least one lower roller is configured to translate up and down the constraint system.
