Abstract

The invention discloses an aero-engine numerical control installation method guided by visual patterns, and belongs to the technical field of installation automation. The aero-engine numerical control installation method is characterized in that a numerical control electric unwheeling is operated to carry out initial alignment on the horizontal axis position and the vertical axis position of an aero-engine according to the relative position information, measured by a pose monitoring platform in an aero-engine numerical control installation system, of the aero-engine and an engine installation cabin, a multi-axis pose adjusting platform is used for accurately aligning the axis position with the axis deviation angle of the aero-engine, automatic whole-course precision installation of the aero-engine is carried out under the real-time monitoring guiding of the pose monitoring platform, and automatic numerical control installation of the aero-engine is achieved. The aero-engine numerical control installation method has the advantages that the advanced image recognizing and measuring technology and the precise numerical control technology are combined to be applied to the installation work of the aero-engine, and the installation efficiency and installation quality are improved.

Description

technical field [0001] The invention belongs to the technical field of installation automation and relates to a visual image-guided numerical control installation method for an aero-engine. Background technique [0002] Due to the size and weight of aero-engines, the narrow installation space, and the complex external structure that does not allow any collisions, it has brought great difficulties and challenges to the high-precision, high-efficiency manufacturing and maintenance of modern aircraft engines. At present, the installation of aero-engines in my country still adopts the traditional manual installation mode, which mainly has the following shortcomings: (1) The detection of the installation process relies on manual experience, and the technical means are backward and prone to repeated misoperations; (2) The accuracy of engine attitude adjustment low, it is difficult to achieve precise adjustment of the position and posture of the engine during installation; (3) the m...
