Filed:

Oct 9, 2001

Appl. No.:

09/973515

Inventors:

Branko Sarh - Huntington Beach CA
Chin Hoi Toh - Orange CA
Chris Erickson - Garden Grove CA
Scott W. Hall - Wentzville MO

Assignee:

The Boeing Company - Seattle WA

International Classification:

B23B 4514

US Classification:

408 1R, 408 97, 408103, 408115 R

Abstract:

A pressure clamp assembly for clamping a plurality of overlapping members together. The pressure clamp includes a pair of compression members attached to a clamp body and driven together by a power source. The power source includes a fluid pressure cylinder that repeatably produces high clamping forces so as to inhibit the production of inter-laminate burrs during drilling. The compression members each include an elongated compression foot that distributes the clamping pressure over a wide area to allow drilling in a relatively wide range of locations. In addition, each compression foot defines a drill bit assembly guide that facilitates accurate hole drilling through multiple overlapping parts.

Assignee:

The Boeing Company - Chicago IL

International Classification:

B23B 45/00

US Classification:

408 97, 408112, 408712

Abstract:

A bushing and associated drill are provided that may be actuated either pneumatically or with a spring in order to be biased into contact with a structure, such as a multi-layer structure, to reduce gaps therewithin. The bushing includes a housing and a nose piece slidably disposed relative to the housing. The bushing also includes a gas inlet in communication with the internal cavity such that the nose piece may be pneumatically urged forwardly relative to the housing and into operable contact with the structure. The bushing may also include a mounting mechanism for releasably attaching the housing to a drill motor. The mounting mechanism permits the housing to be detached from the drill motor to access the internal cavity, thereby permitting a spring to be inserted that will bias the nose piece forwardly relative to the housing. Spring actuation may be an alternative or a supplement to pneumatic actuation.

Assignee:

The Boeing Company - Chicago IL

International Classification:

B23B 35/00
B23B 45/14

US Classification:

408 1R, 408 76, 408 88, 408103, 408235

Abstract:

A burrless, flexible track drilling system employing a counterweight tool balancing subsystem. The counterweight tool balancing subsystem provides essentially a “weightless” feel to a machining subassembly of the system that carries a drill and an electromagnet. This enables an operator to move the machining subassembly vertically with only a very minimal degree of effort being required. The machining subassembly also includes a plurality of lifting subassemblies that aid the user in lifting and lowering the electromagnet away from and toward a pair of panels on which a drilling operation is being performed. This also significantly reduces operator fatigue and contributes to a highly ergonomic system.

Assignee:

The Boeing Company - Chicago IL

International Classification:

G01L 1/10

US Classification:

73862625, 901 34, 901 35

Abstract:

A robotic system comprises an end effector including an electromagnetic clamp, a force sensor attached to the end effector for measuring force exerted by the clamp against a work piece surface, and a plurality of normality sensors. The normality sensors are positioned about the force sensor to determine whether the clamp is normal to the surface before the force sensor makes contact with the surface.

Appl. No.:

13/437532

Inventors:

Chris J. Erickson - Garden Grove CA, US

International Classification:

B23Q 17/00
B23P 21/00

US Classification:

294071, 29705, 901 41

Abstract:

An assembly tool includes a head and an actuator system. The head includes a collar swaging tool that is moveable along a first axis substantially perpendicular to a longitudinal axis of the assembly tool. A sensor system detects a first position of the head within the confined space, and a second position of the collar swaging tool relative to the target object. The actuator system positions the head within the confined space, and the collar swaging tool relative to the target object.

Abstract:

A method of cleaning a surface includes steps of (1) positioning a brush in contact with the surface; (2) rotating the brush relative to a drum about a second axis; and (3) rotating the drum relative to a bracket, supporting the drum, about a first axis, parallel to the second axis, such that the brush orbitally revolves about the first axis.

Abstract:

A method of dispensing a brushable substance onto a surface comprises (1) with a cartridge positioned inside a sleeve between an inner tubular sleeve wall and an outer tubular sleeve wall, circumscribing the inner tubular sleeve wall, and also positioned between a push-lock pressure cap, hermetically coupled with the cartridge, and a valve, communicatively coupled with the cartridge, linearly moving an annular plunger, received between an inner tubular cartridge wall and an outer tubular cartridge wall, circumscribing the inner tubular cartridge wall, toward the valve along a first axis to urge the brushable substance from the cartridge, through the valve, and to a brush that is communicatively coupled to the valve; and (2) controlling flow of the brushable substance from the valve to the brush.
