A one-sided fastener assembly for use in coupling an assembly stack-up includes a sleeve comprising an outer cylindrical surface and an inner tapered surface oriented at a first angle with respect to the outer surface. The inner tapered defines an opening extending through the sleeve. The fastener assembly also includes a core extending along an axis and configured for insertion into the opening. The core includes an outer tapered surface oriented at a second angle with respect to the axis configured for engagement with the sleeve inner tapered surface such that insertion of the core into the sleeve causes radial expansion of the sleeve creating an interference fit with the assembly stack-up to complete installation of the one-sided fastener assembly.

One-sided fastener assembly and methods and systems for installing the same

A fastener insertion system, for use with an assembly stack-up, includes a fastener and an end effector. The end effector includes a drill bit for drilling a hole through the stack-up, a probe for determining a stack-up parameter, and a fastener feed head for installing the fastener into the hole and applying rotational torque to complete fastener installation. The fastener insertion system also includes a processing device and an angle sensor communicatively coupled to the processing device and to the end effector. The processing device is programmed to measure, with the rotation angle sensor, the angular displacement required to complete fastener installation and to transmit a signal representative of the measured angular displacement from the angle sensor to the processing device. The processing device is also programmed to compare the measurement of angular displacement required to complete fastener installation to a range of angular displacement indicative of correct fastener installation.

Systems for in-process quality control during drill-fill assembly

A method for assembling a structure is described. The method includes locating a position in an assembly stack-up where a one-sided fastener is to be installed, drilling a hole through the assembly stack-up at the position, countersinking the hole to a specified depth, operating a calibrated probe to determine at least parameter associated with one or more of the hole and the stack-up proximate the hole, inserting the one-sided fastener into the hole, applying a rotational torque to the one-sided fastener to complete installation of the one-sided fastener, and comparing a measurement of angular displacement required to complete installation of the one-sided fastener to a range of angular displacement indicative of correct installation of the fastener.

A swage collar and an internal sealing insert form a swage collar assembly used in combination with a structural fastener to prevent leakage through a connection of workpieces fastened together by the structural fastener. The swage collar has a hollow, generally cylindrical main body portion with a main central bore, and a base portion with an internal shoulder formed in the main central bore so as to form a seal receiving guide. The shaft of the fastener typically includes a threaded section and an unthreaded section, and the internal sealing insert interfaces with the threaded section and the unthreaded section of the shaft of the pin. In an alternate embodiment, the internal sealing insert interfaces with the unthreaded section of shaft of the pin. The swage collar assembly is fitted over the fastener, a swaging tool is fitted over the swage collar assembly, and the swaging tool is forced over the swage collar assembly with sufficient force to cause plastic deformation in the swaging collar to force the swaging collar and internal sealing insert into engagement with the shaft of the fastener.

The disclosure provides in one embodiment for an integral seal for a drill template tool for a structure having an outside mold line surface fabricated according to a precise definition using computer aided design (CAD). The integral seal comprises an inner surface in contact with an interior portion of a continuous groove portion formed in a bottom surface of a vacuum housing of the drill template tool. The integral seal further comprises an outer surface in contact with the structure. The integral seal is formed in the groove portion on the bottom surface of the vacuum housing, and the groove portion is formed using one of selective laser sintering, fused deposition modeling, or stereolithography, during fabrication of the drill template tool. The integral seal prevents leakage of fluids and debris generated by a drilling process of the structure.

Drill template tool with integral seal

A method and apparatus for performing an operation on a workpiece. Image information may be received from a camera system at a controller in which the camera system and the controller may be associated with a housing. The workpiece with a number of inconsistencies and a tool system may be moved relative to each other under a control of the controller in which the tool system may be associated with the housing. A number of operations may be performed on the number of inconsistencies on the workpiece holes using the image information under the control of the controller.
