Abstract

The invention discloses a non-contact engine blade profile detection device which comprises a rack body and an XZ moving platform which is arranged in the rack body and used for controlling a laser detection assembly to move by a distance in the X-axis direction and the Z-axis direction respectively, a linear laser detection assembly supported against the top of the XZ moving platform and used forcarrying out non-contact data acquisition on the to-be-detected blade, a clamp used for clamping and fixing the blade root part of the to-be-detected blade, a clamp positioning assembly arranged at the top of the rack body and used for detecting and adjusting the installation and positioning of the clamp, and an electric control cabinet arranged on the rack body and electrically connected with the XZ moving platform, the line laser detection assembly and the clamp positioning assembly. According to the non-contact type engine blade profile detection device, the line laser detection assembly is used for collecting and is not in substantive contact with the to-be-detected blade profile, influence of the measuring head on the posture of the to-be-detected blade profile in contact type detection is avoided, and more original data are obtained in a line-to-surface data collection mode.

Description

Technical field

[0001] The present invention relates to the field of engine blade blades, in particular, to a non-contact engine blade blade detecting device. Background technique

[0002] The blade is one of the important components of the engine, and the quality of the blade directly affects the performance, life and safety of the engine. Due to the complex blade structure, the processing and manufacturing is difficult, the design indicators are not easy to guarantee. Effectively control the quality of the blade processing, requires a large number of measurements for the blade type, thereby presented a higher requirement for the detection efficiency of the blade surface. Currently, in the air engine blade surface test, the contact type three-coordinate measuring machine is used for measurement. Due to the constraints of the hardware structure and measurement principle of the contact three-coordinate measuring machine, the measurement speed cannot be too fast, and the measuremen...
