Design of a Linear Displacement Device for High-precision Measuring Instrument

Aiming at the defects of measuring spindle system of traditional length measuring instrument,such as complex structure,cumbersome assembly and adjustment,heavy and high cost,considering the simplified structure and improved measurement accuracy,a kind of linear displacement device with the air damping control is designed by using air damping principle,which is applied to the JC series high accuracy digital display measuring instrument.The research shows that the linear displacement is smooth and steady in the course of measurement,and the stable and reliable measurement is guaranteed,which fully satisfies the operating requirements for high accuracy digital display measuring instrument.
