The Measuring Instrument of Plumb Coaxial Error for Long-distance Orifices Based on Laser Collimation
Introduce the measuring instrument of plumb coaxial error for long-distance orifices which is according to the measuring requests of Flange Place of experiment fast neutron reactor in nuclear power equipment and designed by combining the laser collimation technique and CCD imaging technique. The measuring instrument constructs the plumb line with utilizing the characteristic of laser and making the CDD as imaging screen, and the line is regarded as the datum line in measurement and used for measuring coaxial error of the large orifices manufacture and assemblage under plumb state. Angle resolving power is:0.3;displacement resolving power is:0.02mm; respective degree of uncertainty of measurement results are: 0.1; 0.01mm. The paper detailed introduces the idiographic design principle and measure method of the measuring instrument, and analyzes the measure error. It is applied to measure the precision of manufacture and the coaxial error of assemblage of the large or heavy pipe casting equipment.
