System and method for drilling holes and installing fasteners in vehicle structures
A system and method for drilling a hole in a vehicle structure and installing a fastener in the hole. A drill plate having openings and associated machine-readable elements is positioned on the structure. A drill gun is positioned in a particular opening and reads hole information from the associated element, and a computer determines whether the drill gun is properly set-up to drill the hole. A fastener insertion gun is positioned in the particular opening and reads fastener information from the element, and the computer determines whether the hole has been drilled and, if so, whether the fastener insertion gun is properly set-up to insert the fastener. A fastener delivery subsystem stores, tracks, and delivers fasteners to the fastener insertion gun. A system computer monitors the drilling of every hole, the insertion of every fastener, and the overall operation of the fastener delivery subsystem.
1. A device for installing a plurality of fasteners in a plurality of holes to secure together first and second components of a vehicle structure, the device comprising:
a body comprising a shape which matches a contour of a surface of the vehicle structure;
one or more vacuum connections associated with the body and configured to connect to a vacuum source to create a pressure differential between the body and the surface of the vehicle structure to secure the body to the surface of the vehicle structure;
a backing plate associated with the body and positioned proximate to the plurality of holes in the vehicle structure when the device is in use, and configured to provide a mass against which the plurality of fasteners are struck from an opposite side of the vehicle structure to deform and thereby secure the plurality of fasteners in the plurality of holes; and
a plurality of springs positioned behind the backing plate and configured to bias the backing plate toward the surface of the vehicle structure proximate to the plurality of holes, and further configured to absorb at least a portion of an impact of striking the plurality of fasteners and to maintain the backing plate seated against the plurality of fasteners during repeated strikes by a tool located on the opposite side of the vehicle structure;
wherein the backing plate and the plurality of springs are incorporated into a central element associated with the body, and the central element is removable and replaceable with respect to the body to introduce a different backing plate having a different shape and a different plurality of springs having a different arrangement.
2. The device of claim 1 , wherein the body is a carbon fiber reinforced resin three-dimensionally printed plate.
3. The device of claim 1 , the backing plate further comprising a protective material configured to space the backing plate away from the surface of the vehicle structure.
4. The device of claim 1 , wherein there are at least two rows of springs positioned behind the backing plate.
5. The device of claim 1 , further comprising one or more handles associated with the body and configured to facilitate moving and positioning the device on the vehicle structure.
6. The device of claim 1 , the body further comprising one or more vacuum channels provided on a side of the body which is proximate to the surface of the vehicle structure during use, the one or more vacuum channels being connected to the one or more vacuum connections and configured to facilitate creating the pressure differential to secure the body onto the surface of the vehicle structure.
7. The device of claim 6 , the body further comprising a gasket material positioned and configured to seal the one or more vacuum channels to the surface of the vehicle structure to maintain the pressure differential.
8. A method of using the device of claim 1 , the method comprising:
positioning the body on the surface of the vehicle structure;
connecting the one or more vacuum connections to the vacuum source to create the pressure differential;
positioning the backing plate proximate to the plurality of holes in the vehicle structure; and
repeatedly striking the plurality of fasteners with a tool from the opposite side of the vehicle structure to deform and thereby secure the plurality of fasteners in the plurality of holes.
9. The method of claim 8 , further comprising absorbing impact from said striking by deforming the plurality of springs.
10. The method of claim 8 , further comprising using one or more handles associated with the body to move and position the rivet bucking tool on the surface of the vehicle structure.
11. The method of claim 8 , wherein the vehicle structure is first and second overlapping components of an aircraft body.
12. The method of claim 8 , wherein the plurality of fasteners are rivets.
13. The method of claim 8 , wherein the surface of the vehicle body is an interior surface of an aircraft body.
14. The method of claim 8 , further comprising creating the pressure differential by drawing a vacuum via the vacuum connections through one or more vacuum channels in the body that open through a surface in contact with the vehicle structure.
15. The method of claim 14 , further comprising compressing one or more gaskets to seal the one or more vacuum channels and thereby maintain the pressure differential.
16. A rivet bucking tool for installing a plurality of rivets in a plurality of holes to secure together first and second overlapping components of an aircraft body, the rivet bucking tool comprising:
a body comprising—
a carbon fiber reinforced resin three-dimensionally printed plate comprising a shape which matches a concave contour of an interior surface of the aircraft body, and
one or more vacuum channels and a gasket material positioned and configured to seal the one or more vacuum channels to the aircraft body;
one or more handles attached to the body and configured to facilitate moving and positioning the rivet bucking tool on the aircraft body;
one or more manual vacuum connections attached to the body and configured to connect to a vacuum source to create a pressure differential within the one or more vacuum channels between the body and the interior surface of the aircraft body to secure the body to the surface of the aircraft body;
a backing plate associated with the body and positioned proximate to the plurality of holes in the aircraft body when the rivet bucking tool is in use, and configured to provide a mass against which the plurality of rivets are struck from an opposite side of the vehicle structure so as to deform and thereby secure the plurality of rivets in the plurality of holes; and
a plurality of springs positioned behind the backing plate and configured to bias the backing plate toward the interior surface of the aircraft body proximate to the plurality of holes, and further configured to absorb at least a portion of an impact of striking the plurality of rivets and to maintain the backing plate seated against the plurality of rivets during repeated strikes by a tool located on the opposite side of the aircraft body.
17. The rivet bucking tool of claim 16 , wherein the backing plate and the plurality of springs are physically adapted to fit into a channel formed by a stringer component of the aircraft body in order to install the plurality of fasteners in the plurality of holes within the channel, wherein there is a single row of springs positioned behind the backing plate.
18. A method of using the device of claim 16 , the method comprising:
positioning the body on the interior surface of the aircraft body;
connecting the one or more manual vacuum connections to the vacuum source to create the pressure differential;
positioning the backing plate proximate to the plurality of holes in the aircraft body; and
repeatedly striking the plurality of rivets with a tool from the opposite side of the aircraft body to deform and thereby secure the plurality of rivets in the plurality of holes.
