Research On The Technology Of Planar Form And Position Error Online Measurement For Scroll Compressor’s Scroll

In the trend of increased energy crisis and environmental protection, research on energy-saving and environmentally friendly oil-free scroll compressor is an important direction of development for scroll compressor. The processing quality of scroll directly affect the working performance and service life of the compressor. Research is important to planar form and position error rapid measurement. In this paper, we study several key technologies about planar form and position error online measurement.1. Indicator, coordinate measuring, contour meter and so on-line detection methods are studied. Combined with the feature of measured workpiece feature and tolerance requirements, a kind of non-contact on-line detection of the overall solution is put forward, this paper expounds the detection principle. Select the non-contact sensor, and introduces the data acquisition and motion control system.2. Introduces the mathematical model of the planar form and position error and the least square evaluation algorithm for flatness and parallelism. Write the algorithm program using Visual c++6.0. Error evaluation experiment is implemented. Compare and analyse evaluation results of this algorithm and Amity-8106-type coordinate measuring machine. Verified correctly and effectiveness of this algorithm which is used to scroll plane detection.3. The impact to the measured error of the plane stationing strategy is researched. And based on this, a plane stationing strategy which can take into account the detection efficiency and precision assessment are introduced.4. Introduces the motion control system of the detection scheme, PID and fuzzy control algorithm are studied, and the a fuzzy controller is designed.5. Based on dSPACE, a semi-physical simulation test platform is build, and designed control interface of human-computer interaction with Control Desk. Control models of PID and fuzzy control algorithm are build. Motion control experiment is put into effect and analysis of the experimental results.In this paper, the research work about the scroll planar online measurement technology is valuable to design and development scroll online detection plane.
