A method and device for real-time detection and dressing of end grinding wheel quality

Abstract

The invention discloses a method and device for real-time detection and trimming of the quality of end grinding grinding wheels. The laser beam obliquely shoots to the ground surface of the workpiece, and the receiver continuously receives the reflected laser beam reflected by the grinding surface, and detects the wear degree of the grinding wheel in real time through the energy detection of the reflected laser beam; when the energy of the reflected laser beam of the receiver reaches When the corresponding grinding wheel wear limit value is reached, the grinding wheel is triggered to stop grinding, and the current grinding position of the grinding wheel is recorded by the displacement sensor. The grinding wheel driving mechanism moves the grinding wheel to the position of the grinding wheel dresser and performs real-time dressing; the grinding wheel returns to the The current grinding position continues the grinding stroke of the workpiece surface; the invention can quickly and efficiently realize the on-line detection and dressing of the grinding wheel, and improve the processing quality and grinding efficiency of end face grinding.

Description

Technical field: [0001] The invention relates to a method and a device for real-time detection and trimming of the quality of an end face grinding wheel. Background technique: [0002] In the grinding process, the quality of the grinding surface directly depends on the quality of the grinding wheel, and the grinding wheel is very easy to wear during the grinding process, so the grinding wheel needs to be trimmed in time after working for a period of time to restore the grinding performance of the grinding wheel . [0003] At present, the indirect measurement method is generally used for the wear degree of the end face grinding wheel, that is, the wear degree of the grinding wheel is judged by measuring the surface quality of the processed workpiece. Since the surface quality of the workpiece needs to be measured offline, this dressing method will not only cause workpiece The positioning error also affects the overall processing quality of the workpiece. The most important t...

[0003] At present, the indirect measurement method is generally used for the wear degree of the end face grinding wheel, that is, the wear degree of the grinding wheel is judged by measuring the surface quality of the processed workpiece. Since the surface quality of the workpiece needs to be measured offline, this dressing method will not only cause workpiece The positioning error also affects the overall processing quality of the workpiece. The most important thing is that this dressing method is difficult to accurately determine the time when the grinding wheel needs to be trimmed. The grinding wheel can only be trimmed regularly based on experience, so the grinding quality of the workpiece surface cannot be well controlled.
