Abstract

The invention discloses a device and method to machine root fitting holes in the sidewall of an inner chamber of a composite part. The device is a six-DOF (degree of freedom) cantilever machining device, comprising an X-directional linear moving part, a Y-directional linear moving part, a Z-directional linear adjusting part, an X'-axis cantilever hole-making unit, a Y'-axis rotary adjusting part and a Z-axis rotary adjusting part. A pneumatic motor is used as a rotary spindle power source, so that the device has small size and high speed and is suitable for machining boreholes in composites innarrow spaces. A grinding hole-making mode herein can provide reduced X'-axis force, thereby reducing deformation of cantilever structure and improving drilling precision. The six-DOF cantilever machining device and a fitting hole machining method provided herein provide integral machining for fitting holes in a deep cavity of semi-enclosed structure by single tool adjusting on a single station,and coaxiality and dimensional precision can be ensured for fitting holes of different diameters in a multi-wall plate.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle assembly, and relates to a method for processing an assembly hole at the root of an inner cavity side wall of a connecting section of a wing and a fuselage of a carbon fiber composite unmanned aerial vehicle. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and its own program control device. Compared with manned aircraft, UAV has the advantages of small size, low cost, and convenient use, and is often more suitable for use in harsh environments. It can be used for military reconnaissance, aerial photography, disaster rescue, surveying and mapping and many other purposes. Since unmanned aerial vehicles are of great significance to future air combat, all major military countries in the world are stepping up the research and development of unmanned aerial vehicles. [0003] The application of composite materials on drones greatly r...
