Problems solved by technology
At present, manufacturers of shaft workpieces usually need to customize special measuring instruments for specific shaft workpieces when testing the coaxiality error of shaft workpieces. Not only the measurement process is cumbersome, but also the measurement tools need to be frequently replaced 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 coaxiality error of the shaft workpiece

The invention discloses a coaxiality error measuring method and measuring system. According to the coaxiality error measuring method, measurement of the positional relation data set of different crosssections of the shaft workpiece can be realized by only using laser measuring equipment when the coaxiality error is measured with no requirement for using the customized measuring instrument or thecontact measuring instrument to measure the shaft workpiece so that the possibility of scraping the shaft workpiece in the measuring process can be avoided, the measuring process is simple and convenient and thus the measuring efficiency of the coaxiality error of the shaft workpiece can be enhanced.
Description
technical field [0001] The present application relates to the technical field of geometric quantity measurement of shaft workpieces, and more specifically, relates to a method and system for measuring coaxiality 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 ...
