AI Technical Summary

Technical Problem

During the precision machining of the helicopter platform, the clamping and positioning may cause datum deviations and component deformation, resulting in assembly errors. This can lead to inaccurate or out-of-tolerance precision machining positions, or even product scrap.

Method used

The helicopter platform area is divided into multiple groups. The coordinate transformation matrix between the theoretical processing coordinate system and the actual processing coordinate system of each group is determined. The coordinates of the actual processing points are calculated using the coordinate transformation matrix and then the processing is performed.

Benefits of technology

High-precision machining of helicopter platforms was achieved, reducing the risk of local deviations in finishing and solving the problems of datum deviation and component deformation.

Abstract

The invention relates to the technical field of aircraft assembly, in particular to a helicopter upper platform machining method, system and equipment and a storage medium. The helicopter upper platform machining method comprises the steps that areas, needing to be machined, of a helicopter upper platform are divided into a plurality of groups according to parts; determining a coordinate transformation matrix between the theoretical machining coordinate system and the actual machining coordinate system of each group; and calculating coordinates of actual processing points of each group according to the coordinate transformation matrix, and processing each group according to the coordinates of the actual processing points. The actual state of the helicopter upper platform can be measured on line and automatically processed, automatic compensation and self-adaptive adjustment of the machining coordinates of the upper platform are achieved, and high-precision machining of the helicopter upper platform is achieved.
