Zusammenfassung: | The invention discloses a seven-point type high-speed motorized spindle rotation precision measuring system and method. The system comprises a motorized spindle fixing module, an encoder fixing and fine tuning module, a standard inspection rod, a radial laser displacement sensor fixing and fine tuning module and an axial laser displacement sensor fixing and fine tuning module. The motorized spindle is provided with a temperature sensor. The radial laser displacement sensor fixing and fine tuning module and the axial laser displacement sensor fixing and fine tuning module are provided with seven displacement sensors. Data acquisition is started after the temperature sensor judges that the spindle reaches a thermal stable state, the seven laser displacement sensors perform data acquisition on the motorized spindle in a high-speed rotating state under signals of the encoder, and the data are transmitted to the PC through the high-speed acquisition card. And the PC analyzes and calculates the data to obtain a rot |
