Method and device for detecting and dressing quality of end face grinding wheel in real time

Abstract

The invention discloses a method and device for detecting and dressing quality of an end face grinding wheel in real time. The device comprises a laser, a receiver, a grinding wheel dresser, the grinding wheel, a grinding wheel seat, a displacement sensor and a three-dimensional driving mechanism. According to the device, a laser beam emitted by the laser is obliquely emitted to the ground surfaceof a workpiece, the receiver continuously receives the reflected laser beam reflected by the ground surface, and the abrasion degree of the grinding wheel is detected in real time by detecting the energy of the reflected laser beam; when the energy of the laser beam reflected by the receiver reaches the corresponding grinding wheel wear limit value, the grinding wheel is triggered to stop grinding, the current grinding position of the grinding wheel is recorded through the displacement sensor, and the grinding wheel is moved to the position of the grinding wheel dresser by a grinding wheel driving mechanism and is dressed in real time; and the dressed grinding wheel returns to the current grinding position, and the grinding stroke of the surface of the workpiece continues. The on-line detection and dressing of the grinding wheel can be quickly and efficiently realized, and the processing quality and the grinding efficiency of end face grinding are improved.

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.
