Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0031] The invention provides an on-line monitoring method for grinding wheel wear, such as figure 1 As shown, the first measuring probe 1, the second measuring probe 2 and the third measuring probe 3 are arranged on the rotation plane of the grinding wheel 4, wherein the first measuring probe 1 is installed horizontally, and the first measuring probe 1 and the second measuring probe 2 The included angle between them is α, and the included angle between the second measuring probe 2 and the third measuring probe 3 is β. Point O is the actual center of rotation of the grinding wheel 4, and the centerlines of the first measuring probe 1, the second measuring probe 2 and the third measuring probe 3 intersect at point O. Using the first measuring probe 1 , the second measuring pr...

Abstract

The invention provides a grinding wheel wear online monitoring method. A differential pressure measurement technology and an error separating technology are utilized comprehensively, through change of pressure between the working surface of a grinding wheel and an end surface of a cooling liquid nozzle, a first measuring probe, a second measuring probe and a third measuring probe are used for measuring, and the roundness error of the grinding wheel is obtained by calculation, a measuring system for measuring wear extent and blunting degree of the grinding wheel in an online manner is established, online detection of wear degree of the grinding wheel is realized well, and the measurement precision is good.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and engineering testing, in particular to an online monitoring method for grinding wheel wear. Background technique [0002] Since the 1960s, people have carried out research on grinding wheel wear, passivation and topography. More than ten kinds of detection methods have been proposed successively, which can be divided into two categories: online dynamic detection and shutdown static detection. Static methods mainly include: stylus method, imprinting method, optical section observation method and electron microscope observation method. Online dynamic detection methods mainly include: temperature measurement and force measurement method, scratch copying method, hydraulic method, air pressure method, laser detection method, photoelectric detection method, computer vision detection method, and acoustic emission method. However, so far, there is no mature online detection method that h...
