Abstract

A method of on-line measurement which is based on a loser displacement sensor to measure external profile of non-circular piston is proposed. Measurement coordinate system is established on the basis of the reference cylinder. Measurement data is processed through least square method to achieve the actual value of piston-section. Compared the actual value with the designed value can determine whether the cross section of piston is qualified. Fitting spatial line which is consisted of a plurality of cross-sectional center forms the axis of the elliptic cylinder. Then we can obtain straightness of the piston neutral line. The method of on-line measurement is validated through making specific experiment. This method is available to evaluate processing quality of external contour. At the same time, it is also helpful to make on-line processing correction for piston.
