Problems solved by technology
At present, when the shaft workpiece manufacturers detect the cylindricity error of the shaft workpiece, they usually need to customize a special measuring instrument for the specific shaft workpiece. Not only the measurement process is cumbersome, but also the measurement tool needs to be replaced frequently during the measurement process. Especially when using a contact measuring instrument for measurement, there is still the possibility of scratching the shaft workpiece, and the degree of automation is low, which restricts the further improvement of the measurement efficiency of the cylindricity error of the shaft workpiece

The application discloses a cylindricity error measuring method and measuring system. According to the cylindricity error measuring method, there is no need to use a customized measuring instrument and a contact measuring instrument to measure a shaft part after the fitting cylindrical surface of a certain step of the shaft part is obtained. The shaft part is prevented from being scratched duringmeasurement, and the measurement process is simple. Therefore, the measurement efficiency of cylindricity error of shaft parts is improved.
Description
technical field [0001] The present application relates to the technical field of geometric measurement of shaft workpieces, and more specifically, to a method and system for measuring cylindricity errors. Background technique [0002] In the field of precision manufacturing in the machinery industry, the processing and testing of shaft workpieces is always an important and complicated problem. From a certain point of view, the detection accuracy in the manufacturing process of shaft workpieces negatively restricts the machining accuracy. Improving its on-line detection ability and ensuring the processing quality is of great significance to promote the development of shaft workpiece manufacturing level. [0003] According to incomplete statistics, the total annual output of shaft parts in my country is about 1 billion pieces, but the competitiveness in the international market, especially the high-end shaft market, is very limited. The industry as a whole has an urgent need ...
