Abstract

The invention relates to a precise on-site measuring device and measuring method for sphericity of a spherical surface, belonging to the technical field of mechanical measurement. The measuring device comprises a main shaft mechanism, a rotation mechanism, a driving mechanism, a sensing mechanism and an encoder mechanism, wherein a workpiece to be measured is arranged on the main shaft mechanism;the center of the rotation mechanism is rotatably connected with the main shaft mechanism; the sensing mechanism is fixedly arranged on the rotation mechanism and is connected with the encoder mechanism; and the driving mechanism is connected with the rotation mechanism. Compared with the traditional off-line manual measuring method or measuring method by a three-coordinate measuring machine, theinvention has the advantages of high detecting speed and high degree of automation on the premise that the precision of measurement is ensured, and realizes automatic on-site measurement of the sphericity error.

Description

technical field [0001] The invention relates to a device in the technical field of mechanical measurement and a measurement method thereof, in particular to an in-situ measurement device and a measurement method for precision spherical sphericity. Background technique [0002] The sphericity error has an important influence on the rotational motion of mechanical parts. Defects such as spherical roughness, spherical waviness, and shape errors will lead to wear and premature failure of parts. Accurate and efficient evaluation of spherical error is very important. The traditional measurement method is to use a micrometer to measure the diameter of the sphere multiple times to roughly estimate the sphericity error. Or evaluate the sphericity error by measuring two or three mutually perpendicular great circularity values ​​on the measured sphere. These methods only reflect the local information of the spherical surface, and cannot accurately evaluate the three-dimensional spher...
