Research For Online Automatic Measuring System On Centerless Grinding

To improve the quality of machine work pieces, on-line measuring technology is adopted on grinding machine to form a closed-loop grinding system. Taking the outside-diameter measurement of the spindle, method of how to use the raster transducer to realize the on-line measuring system on the grinding is introduced in this article.This paper has carried on analysis and discussion to various measuring methods,in order to realize requirements of various fields such as high precision,low cost with high efficiency, adopt raster transducer to measure work piece g online.The main research contents of this article are making use of SCM to realize on the center-less grinding machine to measure the work piece online,and form a closed-loop grinding system,in order to control the precision of piece,further, form a nobody, high precision and high efficiency producing mode, mainly included:Choosing the measurement method and transducer. It should guarantee firstly that there is enough high static precision to measured online.This text has carried on the made a deep analysis for the realize high precision raster transducer on its principle, and static behavior to its parameter standard, carry on numerous calibration analysis characteristic of the to the transducer of the existing grating, receive the dynamic characteristic existing transducer.Designing the mechanical equipment. The content mainly explained is that the structural design of the measuring device for the center-less grinding machine,and has made the summary about its whole function and analyzed the choice of the important part; Finally, the work about sketching the three-dimensional entity's model for the measuring equipment is related.Designing the part of automatically software and hardware control. According to the requirement for the center-less grinding machine measuring online, a SCM system is designed which can gather, deal with, reveal the signal outputted from the transducer and the serving circuit, feed back to the grinding machine to realize to control the grinding machine. Errors of the whole on-line measuring system are analyzed at the final part of the article.This subject can realize the destined requirement through debugging the simulating software, prove the scheme of this automatic measuring system is feasible.lt is not only establishes the basic for the grinding machine to realize measuring online, but also offer a kind of route and scheme to the other transformations of different lathes at the same time.
