Grinding wheel sharpening finishing image visual monitoring device and method

Abstract

The invention discloses a grinding wheel sharpening finishing image visual monitoring device, and the device comprises an image collection apparatus which is used for taking a picture of three-dimensional shape of a surface micro-abrasive-particle edge of a grinding wheel; an image and machine vision processing system which enables an abrasive particle three-dimensional point cloud shape to be displayed through a three-dimensional reconstruction method; and a CNC integrated control system which is used for observing the condition of the micro-abrasive-particle edge according to the abrasive particle three-dimensional point cloud shape and adaptively adjusting the sharpening finishing technological parameters of the grinding wheel, thereby achieving the online monitoring and intelligent control of the sharpening finishing of the grinding wheel. The invention also provides a grinding wheel sharpening finishing image visual monitoring method. The device employs a high-definition CCD camera and the image and machine vision processing system, extracts the features of the abrasive particle three-dimensional point cloud shape of the surface of the grinding wheel, reconstructs the three-dimensional point cloud shape, restores the condition of the micro-abrasive-particle edge, feeds back the condition to a machine tool CNC control system, adaptively adjusts the sharpening finishing technological parameters, and achieves the online monitoring and intelligent control of the sharpening finishing of the grinding wheel.

Description

technical field [0001] The invention relates to the field of grinding wheel sharpening and dressing for precision grinding manufacturing, in particular to an image visual monitoring device and method for grinding wheel sharpening and dressing. Background technique [0002] The key to precision / ultra-precision machining technology when grinding wheel sharpening and dressing, how to efficiently monitor grinding wheel sharpening and dressing on-site / online has always been the technical bottleneck of industrialization. Under normal circumstances, it is necessary to use scanning electron microscope or white light interferometer and other off-line detection methods to determine whether the abrasive grains on the surface of the grinding wheel are fully edged or not, which makes the grinding wheel sharpening and dressing efficiency low, and it is difficult to grasp the grinding wheel surface sharpening and dressing situation. Therefore, the present invention proposes an image vision...
