Problems solved by technology

At present, the posture adjustment and positioning of the main unit body are mainly completed manually with the help of a crane. After the assembly is completed, the inspection personnel mainly inspect the assembly quality through visual inspection. However, the visual inspection method has the disadvantage of being difficult to accurately record and trace the quality status
However, high-performance engines have more precise coupling and fit (clearance, interference) requirements, which makes the current quality inspection methods face greater challenges

Abstract

The invention discloses a high-precision aircraft engine assembly quality detection robot system, and relates to the technical field of aircraft engine assembly quality detection. According to the system, quality data of an engine are acquired by an industrial camera and an optical measuring device on a mechanical arm, a three-dimensional model is built by a computer according to the quality data,a detection result is judged, displayed to a detector and stored, rapidness and accuracy of the detection result of engine quality are powerfully ensured, and the detection result is timely and accurately recorded and traced.

Description

technical field [0001] The invention relates to the technical field of engine assembly quality inspection, in particular to a high-precision assembly quality inspection robot system for aero-engines. Background technique [0002] The assembly of the main engine of the aero-engine, that is, the precise installation between the main units, is the core technical content of the engine assembly process, and it is also the main process difficulty and weakness of the current engine assembly. At present, the attitude adjustment and positioning of the main unit body are mainly completed manually with the help of a crane. After the assembly is completed, the inspection personnel mainly inspect the assembly quality through the visual inspection method. However, the visual inspection method has the disadvantage of being difficult to accurately record and trace the quality status. However, high-performance engines have more precise coupling and fit (clearance, interference) requirements,...
