Abstract

The invention relates to an online measuring device and method of roller roundness and roller-shaped error for roller grinding machine with high precision. The roller can be mounted with eccentricity, the machine tool principal axis error and the machine tool guide error are separated by the two point error separating method, thereby greatly improving the measuring precision of the roller. When measuring the roller diameter, this measuring device can realize a plurality of measurements by one calibration. The invention has advantages that: a measuring device with two point error separating is provided, the data calculation measured by the device is simple, the measuring precision and the measuring efficiency of the roller is greatly improved. When an eddy-current test sensor 22(D) is mounted on the device to realize on-line monitoring of the roller surface quality.

Description

technical field [0001] The invention relates to a device for on-line measurement of roll roundness and roll shape on a numerically controlled roll grinder, which can separate roll installation eccentricity, machine tool spindle motion error and machine tool guide rail error by a two-point error separation method, thereby greatly improving Roll measurement accuracy. When measuring the diameter of the roll, the measuring device can realize one calibration and multiple measurements. Background technique [0002] With the rapid development of metallurgy, steel and automobile industries, the precision requirements for metal sheets are getting higher and higher. In order to press high-precision plates, the quality of the rolls is very important. Among them, the roundness of the roll, the accuracy of the roll shape and the surface quality of the roll are the most important factors to determine the accuracy of the plate, and the final quality of the roll is determined by the roll ...
