A circular linkage error measuring device with rotation angle feedback function

Abstract

The invention discloses a circular ganged error measuring device with a rotation angle feedback function, and relates to a ganged error measuring device. The circular ganged error measuring device is provided with a base, a fixed end ball journal and a telescopic measuring rod, wherein a reading head support is arranged on a shoulder of the fixed end ball journal; a reading head is arranged on the reading head support; a grating support disk is arranged at one end of the shoulder of the fixed end ball journal, and can rotate around the fixed end ball journal; a circular grating glass coded disc is arranged on the mounting surface of the grating support disk; a shaft sleeve is arranged on the telescopic measuring rod; when a moving end of the telescopic measuring rod does circular arc motion, the shaft sleeve can drive the grating support disk to synchronously rotate, and the circular grating glass coded disc is enabled to rotate; the reading head stationary relative to the base is arranged below the circular grating glass coded disc, and is used for reading rotation angle data. The circular ganged error measuring device has the advantages of simple structure, small space volume, convenience in carrying and mounting and high practicality. By synchronous measurement of a rotation angle, angle errors are greatly reduced, and high-precision processing of a data separation algorithm is effectively guaranteed.

Description

technical field [0001] The invention relates to a linkage error measuring device, in particular to a circular linkage error measuring device with a rotation angle feedback function. Background technique [0002] The high-precision machining of machine tools has become the focus of industry insiders. The accuracy of the machine tool itself is an important factor affecting the machining accuracy. How to quickly and effectively diagnose the main errors of the machine tool and improve the accuracy of the CNC machine tool through compensation is a very important task. As a kind of precision processing equipment, CNC machine tools not only have errors caused by various non-mechanical reasons such as manufacturing errors, assembly errors, and servo system errors. In actual use, many errors cannot be completely eliminated. With the use of the machine tool and the wear of internal parts, the comprehensive error of the machine tool will become larger and larger, which directly affect...
