Automated Fastening

E7000 Fuselage Riveting Machine

The E7000 is a gantry-style, D-Frame fuselage riveting machine designed to meet the requirements of Turkish Aerospace Industries for a high-speed CNC machine capable of fastening high-curvature panels. Processes include drilling and installation of rivets and interference-fit bolts with sealant, automatic resynching, and automatic flushness measurement.

Unlike traditional part positioners, the E7000 positioner uses two fully servo-driven independent positioner towers. This allows the part to be held in a minimalist support structure for maximum fastening access to areas of high curvature. The E7000 fastens panel edges of 120° fuselage sections, and up to 150° is possible. A conventional part positioner is also available.

An open process head design and a cantilevered fixed platform allow easy maintenance access. A man lift or ladder is not required to reach the head, and all sides of the head may be reached safely and comfortably. This concept provides a significant improvement in maintenance accessibility as compared the standard for gantry or c-frame-style machines. The machine is also equipped with a lowering platform for quick access to the head while in production and away from the fixed platform.

The E7000 utilizes an array of newly designed, patent-pending fastener injectors that are capable of automatically recovering from virtually all fastener jams, including those caused by multiple or backwards-fed fasteners. Integrated length checking and tipped fastener checks are performed. The E7000 also includes automatic tool changing for cutters and upper anvils, and a sealant inserter capable of sealing multiple hole diameters with a single nozzle. These features make it possible to operate with little manual intervention on the upper head. In fact, no access to the upper head is necessary to switch between fastener types and diameters.

The E7000 comes in two configurations. The baseline configuration has a max part positioner width of 3.5 meters and the extra-large configuration has a max part positioner width of 5.5 meters. Both the baseline and extra-large configurations have a length that is built to order to accommodate a wide variety of parts.

E6000 Gantry Wing Panel Riveter

Wing panel fastening machine designed with a focus on speed and reduced weight. The E6000 is a Low-Voltage Electromagnetic Riveting (LVER) machine. The machine installs slug rivets at a rate of 16 per minute in a drill-upset-shave cycle. It is being built for a customer in Xi’an, China where it will fasten wing panels for the ARJ21 regional jet. The machine is built to accommodate slightly larger wing panels, in the size range of A320 and 737. Its configuration can be scaled to other panel sizes.


E5000 Full Barrel Fastening System

An automated machine has been designed with true offset fastening to join shear-tie/frame assemblies to the fuselage of the Boeing 787 Dreamliner. The machine can access fasteners located close to structural components that are very deep. This is accomplished by offsetting the fastening axis from the axis of the head for true offset fastening. The head can be positioned next to the structural component and the offset fastening tooling 'reaches' out to the fastener location.


E4000 Wing Panel Travelling Yoke

The patented E4000 is a vertical yoke rivet/bolt machine for wing panel assembly. In the E4000 the yoke moves in five axes. Due to the use of electromagnetic riveting (EMR) the yoke can install rivets into rigid fixture assemblies. This allows the yoke to run over the panel build and install all of the rivets and lock bolts. Splice fasteners are also installed. Hence all tack fasteners are eliminated.


E3000 Vertical Spar Riveting Machine

The E3000 was developed for Boeing and Electroimpact's line of Automatic Spar Assembly Tools.
