Design of Intelligent Measuring Device for On-line Machining Parts of Lathe

To be higher the production efficiency of mechanical parts, after analyzing the shortcomings of conventional parts dimension measurement technology, a design scheme of automatic device which can realize on-line dimension measurement of parts by lathe is proposed. It integrates the work of lathe processing, dimension measurement and quality appraisal into one process innovatively. This scheme uses projection optical system to replace the traditional scanning scheme. The measuring device can not only complete the real-time and high-precision measurement of 15 parameters, but also ensure easy operation and maintenance. At the same time, the optical system design has a collimated beam expanding path, which makes the measuring device have a larger measurement range. Combining with the working environment of the measuring device, the design of the shock absorption mechanism is introduced in the structural design, so that the high stability of the measuring results can be maintained under the normal operation of the lathe. Finally, by extracting feature parameters and testing the matching interface, it is proved that the designed device fully meets the technical requirements proposed at the beginning of the study.
