Automatic Drill Riveter Cell

The Electroimpact Automatic Drill Riveter (ADR) combines a number of Electroimpact’s core competencies to provide an elegant and flexible design solution. The offering consists of a stationary Electro-squeeze C-frame riveter, coupled with a robot part positioner to present the component to the process head tool point.

The C-frame can install a wide range of aerospace rivets and perform specialist functions including backside countersinking operations, giving potential for double flush fastening. The geometric limitations and high implementation costs of large cartesian based positioning barges or fixed jig tooling and moving gantry riveters are avoided when exchanged for a robot part positioner. To achieve the high levels of accuracy and repeatability required within the industry the robot part positioner is a KUKA KR1000L750 upgraded with EI proprietary Accurate Robot Technology delivering +/- 0.25 mm large volume global accuracy.

Critical to the success of the system is high speed and seamless communication between the robot and C-frame, this is achieved by deploying a Siemens 840D CNC as the singular central controller handling the robot motion control, riveting process and cell safety features. With twenty-seven individual servo driven axis’ working in harmony to perform the core manufacturing functions the single 840D
controller allows for a more efficient and simplistic control architecture.

This automation is suited to manufacture small and medium sized aerospace assemblies such as flaps, doors and spoilers
