US Patent:

7503733, Mar 17, 2009

Filed:

Aug 17, 2006

Appl. No.:

11/505565

Inventors:

William L. Jenkins - Burleson TX, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

B23B 49/02

US Classification:

408 97, 408110

Abstract:

A system, method, and apparatus for the rigid alignment of drill bits with ergonomic drill motors is disclosed. An adjustable nosepiece adapter is mounted to the ergonomic drill motor adjacent the drill bit chuck. The adapter has a split clamp portion on its distal end for receiving a pressure foot. A guide bushing fits in the proximal end of the pressure foot. A coil spring is located in the pressure foot and allows the guide bushing to telescope within the pressure foot. The drill bit extends through the guide bushing, pressure foot, and adapter and is secured to the chuck. The distal end of the guide bushing fits closely within a hole in a template that is secured to the workpiece to provide holes that are more accurately formed in the workpiece.

Abstract:

A system for removing failed fasteners from structures removes the head of the fastener in a controlled manner with precise support and alignment for the cutting tool. A drill guide, drill bushings and the cutting tool mount virtually anywhere on an underlying structure using existing fasteners and receptacles formed in the structure. This design permits the drill guide to be rigidly attached to the structure so that the cutting tool can be positioned and supported directly over the failed fastener. After the drill guide is mounted, a drill bit is extended through the drill bushing to drill a pilot hole in the failed fastener. The cutting tool is used through the drill bushing to cut off the head of the failed fastener without contacting the surrounding structure. All operations required to remove the failed fastener are accomplished through the drill bushings contained in the mounted drill guide.
