A method and apparatus are used to visually recognize and install fasteners on a structure. An electronic image of the fastener is recorded, and is processed by a computer operated image recognition program to identify the fastener. The computer provides installation instructions and an installation tool based on the identity of the fastener.

Intelligent fastener system

A method and apparatus for processing a fastener system. A fastener installation tool may be placed on a surface of an object. An elongate structure may be attached to the fastener installation tool and may have a length. A camera may be associated with the fastener installation tool in which the camera may be configured with a focal length corresponding to the length of the elongate structure. The camera also may be configured to capture an image at least a portion of the fastener system when the elongate structure is placed against the surface of the object on which the fastener system is located. The image of the at least a portion of fastener system may be captured.

Method and apparatus for establishing a camera focal length for installing fasteners

A temporary fastener includes a grip length indicator. By machining a flattened area into a body of the temporary fastener, by engraving an scale into the flattened area, and by attaching an indicator dot visible in the groove to a moving part of an internal assembly of the temporary fastener, the grip length of the installed temporary fastener may be read directly on the scale while the temporary fastener applies a clamp-up force to a structure. By using the temporary fastener of the present invention, it is possible to determine a fastener hole length while a temporary fastener is installed. Using the method for determining a fastener grip length of the present invention enables the effective determination of the correct fastener grip length for each particular fastener hole of a large structure, such as an aircraft airframe.

Clamping fastener grip length indicator

A fastener grip length selector includes a housing having a first section and a second section, and a gauge fitted with the second section of the housing and including a spindle that reaches into the first section of the housing. The fastener grip length selector enables the precise determination of a grip length of a fastener to be installed in a particular fastener hole while a temporary fastener is installed in that particular fastener hole. The fastener grip length selector is suitable for, but not limited to, applications in the aerospace industry. The fastener grip length selector may be used, for example, during the installation process of an aircraft airframe assembly. Using the method for precisely measuring a thickness of an assembly in clamped-up condition enables the determination of the length of a blind fastener hole with high accuracy while a temporary fastener is installed.
