It was proposed to adopt multi-nozzle pneumatic linear measuring needle in a buoy pneumaticmeasuring instrument to measure internal bore straightness. The measurement principle and method of themulti-nozzle pneumatic linear measuring needle were investigated and analyzed. A multi-nozzle pneumaticlinear measuring needle and its calibration ring were designed and manufactured. The method of measuringinternal bore straightness with multi-nozzle pneumatic linear measuring needle was verified by means ofthe example. Instances show that the measurement of inner bore straightness by pneumatic linear measuringneedle on the buoy pneumatic measurement instrument with multiple nozzles is efficient and accurate. Thedesign of pneumatic linear measuring needle is practical and reliable, completely satisfying the require.ments of customers, to fill in the technology gap of industry.
