Blade grinding and polishing vibration detection system and method based on vision

Abstract

The invention discloses a blade grinding and polishing vibration detection system based on vision. The blade grinding and polishing vibration detection system comprises an illumination system, a CCD camera, an image acquisition system, an imaging system, a computer system and a display device. The lighting system is used for providing light sources for the system; the imaging system is used for imaging spatial structure information of the blade on the CCD camera; the CCD camera and the image acquisition system convert acquired image optical signals into electric signals; the CCD camera converts the analog image signal into a digital image signal and transmits the digital image signal to the computer system; the computer system receives the digital image signal, processes the image throughan image processing algorithm to obtain a blade characteristic parameter, and obtains blade vibration information according to the blade characteristic parameter; and the display equipment displays the blade vibration information. The invention also discloses a corresponding detection method. By means of the scheme, vibration of blade grinding and polishing machining can be effectively detected, and the beneficial effects of being convenient to measure, wide in measuring range, high in precision and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of robot processing detection, and more specifically relates to a vision-based blade grinding and polishing vibration detection system and method. Background technique [0002] In the industrial field, blades play an important role in aero-engines, steam turbines and gas turbines. As the core components, blades directly determine the overall working performance and service life. The surface quality and processing accuracy of the blade after grinding and polishing directly determine the performance of the blade. Improving the surface processing accuracy of the blade is an important issue that needs to be solved urgently in the grinding and polishing of the blade. The curved surface of the blade is a complex curved surface, the degree of blade distortion is large, and the machining accuracy is difficult to guarantee. The traditional manual grinding and polishing process has great differences in quality, poor c...
