A method and device for in-situ measurement of radial runout of grinding wheel

Abstract

The invention relates to an in-situ measurement method for radial run-out of a grinding wheel, and an in-situ measurement device for radial run-out of the grinding wheel. According to the in-situ measurement method and device for radial run-out of the grinding wheel, the radial run-out of the grinding wheel and the phase angle of radial run-out on the circumference of the grinding wheel are measured at the same time, and therefore run-out of different positions on the surface of the grinding wheel can be conveniently and accurately analyzed; and furthermore, in-situ measurement is achieved, positioning deviation caused by disassembling and assembling of the grinding wheel is avoided, and precise in-situ measurement of radial run-out of the grinding wheel is efficiently achieved. By means of the lever principle, the radial run-out change of the grinding wheel is converted into rotation displacement of a lever through a contact head and detected by a displacement sensor, the distance between a measurement point of the displacement sensor and the starting end of the lever is larger than the distance between the contact head and the displacement sensor, and therefore radial run-out of the grinding wheel is measured after being amplified, the measurement difficulty is lowered, and precise in-situ detection of trace radial run-out of the precise grinding wheel is achieved.

Description

technical field [0001] The invention relates to the measurement technology of the radial runout of the grinding wheel, more specifically, to an in-situ measurement method for the radial runout of the grinding wheel and an in-situ measurement device for the radial runout of the grinding wheel. Background technique [0002] Grinding is the main processing method for precision forming and high-quality surface of mechanical parts. Among them, using grinding wheels as tools for grinding is the most widely used method of grinding. Grinding wheel grinding is to use the abrasive material on the surface of the working layer of the outer circle of the grinding wheel under high-speed rotation to remove the workpiece material, and the radial runout of the outer circle of the grinding wheel directly determines the quality of the processed surface. If the radial runout is too large, not only the surface quality of the ground workpiece will be poor, but also the vibration will be severe du...

AI Technical Summary

Problems solved by technology

[0008] However, the technical solution of the above-mentioned patent application is directly or indirectly measured in equal proportions, and the radial runout of the grinding wheel is very small. Accurate and effective measurement is required, and high-precision measuring instruments must be used, which is not only costly, difficult to operate, but also impossible. Larger errors to avoid;

[0009] Moreover, the measurement methods in the prior art only measure the outer circular runout of the grinding wheel, and there is no corresponding correlation between the measured radial runout of the grinding wheel and the specific position of the grinding wheel, and the specific details of the high and low points on the grinding wheel are not accurately measured. position, although there is obvious runout on the grinding wheel, it is impossible to measure the specific position of the jumping high and low points on the grinding wheel, and thus it is impossible to control the grinding wheel in a targeted manner

[0010] The above problems seriously restrict the high-efficiency and high-quality processing of grinding wheel grinding.
