Three Coordinates Measuring Instrument Ultra-precision Machine Mechanism Design
ABSTRACT
 In this paper, three coordinates measuring instrument for precision measurement, the research present situation and the key technology of summing up, the design of measuring instrument lathe bed of the general layout, the design of the selection of materials, guide rail, into to the choice of the ways of doing introduced, choose coattails "type aerostatic guide rail, synchronous cog belt and steel belt transmission, friction lever driven. Slip board of mobile bridge and the simple ANSYS analysis method, the largest mobile bridge when stress deformation and straightness; Choose servo motor as a power source, and analyses the simple power calculation, analyzes the working environment of measuring apparatus to the precision of the influence and its application environment; The positioning of grating open grating feet, comparison of the selection of the feet. Finally, according to the measuring apparatus for precision analysis, find the error sources and precision of the comprehensive analysis.
Keywords: The ultra precision, Gas static pressure, High accuracy, Precision measurement
