Abstract

The invention relates to a precise main shaft rotation accuracy detecting device and method, and belongs to the technical field of measuring precise main shaft rotation errors. The detecting device comprises an atomic force microscope (AFM), a plane sample, a manual two-dimensional adjusting platform, a two-dimensional electric displacement platform and a precise main shaft controller, wherein the AFM is used in cooperation with the plane sample to obtain a scored morphology graph, the plane sample is fixed to the upper portion of the manual two-dimensional adjusting platform, the bottom of the manual two-dimensional adjusting platform is connected with the upper end of a precise main shaft to be detected, and the lower end of the precise main shaft to be detected is connected with the two-dimensional electric displacement platform. The detecting device and method use the advantage of nanometer scoring machining and detecting integration of the AFM, it is unnecessary to adopt a datum part in the detecting process, operation is easy, the measurement accuracy can reach the nanometer order, radial and axial rotation errors of the precise main shaft can be detected at the same time, and the accuracy of the rotation errors of the precise main shaft is improved.

Description

technical field [0001] The invention relates to a precision spindle rotation accuracy detection device and method, belonging to the technical field of precision spindle rotation error measurement. Background technique [0002] With the development of ultra-precision machining technology and nanotechnology and the improvement of product manufacturing accuracy, the requirements for machining accuracy of machine tools are getting higher and higher. The detection of machine tool spindle rotation accuracy is an important link in the design, manufacture, adjustment and maintenance of machine tools. An important measure of machine tool machining accuracy. The spindle rotation error is the displacement of the spindle's instantaneous rotation axis relative to the average axis. The spindle rotation error can be roughly divided into two basic forms: the axial end face runout and the radial rotation error. The spindle rotation accuracy is the position reference and movement of the workp...
