Abstract

The invention discloses a non-contact engine blade profile detection method and an engine blade. The method comprises the steps that a clamp carries out the partial clamping and fixing of the blade root part of a to-be-detected blade, and is installed and fixed on a clamp positioning assembly of a detection device; a control system controls an XZ mobile platform of the detection device and drivesthe line laser detection assembly to reach the data acquisition position of the to-be-detected blade, data acquisition of the lower half part of the to-be-detected blade and the upper half part of theto-be-detected blade is carried out, the acquired data is fused, a complete blade data point cloud model is obtained, a theoretical reference of the to-be-detected blade is determined according to the blade data point cloud model to complete absolute positioning of the to-be-detected blade, the size of the blade profile of the to-be-detected blade is calculated, and a detection result of the blade profile of the to-be-detected blade is output. According to the non-contact engine blade profile detection method, non-contact detection is achieved, more original data are obtained in a line-to-surface data acquisition mode, and the detection precision is improved.

Description

technical field [0001] The invention relates to the field of engine blade airfoil measurement, in particular to a non-contact engine blade airfoil detection method. Background technique [0002] The blade is one of the important parts of the engine, and the processing quality of the blade directly affects the performance, life and safety of the engine. Due to the complex structure of the blade, it is difficult to process and manufacture, and the design index is not easy to guarantee. To effectively control the processing quality of blades, a large amount of measurement work is required on the blade profile, which puts forward higher requirements for the detection accuracy and efficiency of the blade profile. At present, in the detection of the profile of aero-engine blades, the contact type three-coordinate measuring machine is mainly used for measurement. Due to the limitations of the hardware structure and measurement principle of the contact three-coordinate measuring m...
