High-precision solving device and method for calibrated and fitted circle centers

Abstract

The invention provides a high-precision solving device and method for calibrated and fitted circle centers. The high-precision solving device for the calibrated and fitted circle center is arranged inside a machine tool and is used for performing calibration on a probing head and obtaining a fitted circle figure and the fitted circle center error of a calibrating component used for calibrating the probing head so that the operating staff can judge the error of the machine tool according to the fitted circle center error conveniently. The high-precision solving device for the calibrated and fitted circle centers is characterized by comprising the calibrating component, a data measuring portion, a data fitting portion, an image fitting portion, a circle center gathering portion, a circle center fitting portion, a data calculating portion and a displaying portion. The data measuring portion is used for performing point-by-point detection on the calibrating component and obtaining coordinate data of the probing head; the data fitting portion is used for performing fitting on the coordinate data of the probing head; the image fitting portion is used for fitting out the fitted circle figure and the fitted circle centers; the circle center gathering portion is used for combining the fitted circle centers into a group of dispersed fitted circle centers; the circle center fitting portion is used for performing weighted average and iterative optimization treatment on the dispersed fitted circle centers and obtaining the true circle center coordinate; the data calculating portion is used for calculating the straight-line distance between any two fitted circle centers; and the displaying portion is used for displaying the figure and data.

[0005] However, due to the existence of machine tool errors, the most accurate coordinate values ​​are often not obtained by only one fitting, which directly affects the accuracy evaluation of online gear measurement, and ultimately affects the gear grinding accuracy

In addition, the current existing measurement system can only be transferred to commercial processing software such as Matlab, Mathmatica, Maple, and OriginLab after the measurement data is obtained during the probe calibration process, and most of the domestically produced The machine tool does not include the automatic calculation software of the fitting circle of the calibration probe, which increases the complexity of the probe calibration, not only wastes processing and production time, but also the existing machine tool does not have an instant display function during calibration, and users cannot monitor it online in real time
