SYSTEM FOR DRILLING PANELS DURING FINAL ASSEMBLY OF AIRCRAFT Russian patent published in 2021 - IPC B23B35/00 B23B39/14 

FIELD: aircraft construction.

SUBSTANCE: invention relates to a device made with the possibility of programmed drilling of external panels, such as aircraft skin elements, and their attachment to connecting structures, such as frames, stringers, ribs and/or spars. The working body is made with the possibility of fixing and through drilling a pair of components during final assembly under the action of clamping forces sufficient to avoid separation of these components for deburring after drilling. At the same time, the working body contains an automated drilling head, which includes a drill and a dispenser for sliding clamps, made with the possibility of inserting sliding clamps into various pre-drilled guide holes, extending the sliding clamps and removing them from various pre-drilled guide holes in these components during final drilling of the fastener holes in the specified components. Moreover, the dispensing device for sliding clamps comprises a magazine designed to selectively supply and withdraw multiple sliding clamps during the final drilling. At the same time, the magazine is designed for rotation and step-by-step movement. Moreover, the magazine is designed to successively dispense sliding clamps and rotate one of the pair of recesses located in the rounded side of the magazine to the position on top of the sliding clamp of the device for installation/extraction, and the sliding clamp of the device for installation/extraction is designed to sequentially insert the sliding clip removed from the magazine slot into the pre-drilled guide hole near the original location of the hole for the fastener. Moreover, the dispensing device for sliding clamps provides a tight fastening of the selected part of these components under the action of temporarily applied specified clamping forces during each case of automated drilling of holes for fasteners in these components. The group of inventions also relates to a system for using a variety of electronically programmable working bodies and to a method for ensuring the final assembly of the wing skin of an aircraft with its installation on a variety of structures of the ribs and/or wing spars.

EFFECT: proposed group of inventions makes it possible to easily drill holes for fasteners in the wing panel of an aircraft and the internal structures of the ribs and / or wing spars under the action of clamping forces sufficient to avoid separation of the wing panels for deburring, cleaning and sealing during operation.
