Design of Measuring System for Conical Shell Gluing Platform and Analysis of Factors Influencing Measurement

Abstract:

As a cover to prevent the inside system from being destroyed, conical shell is widely used in national defense and meteorological fields. Radial runouts at specific cross sections of conical shell need to be measured before and after gluing for coaxiality requirement between conical shell and connecting ring. So a measuring system of vertical gluing platform was designed. Noncontact laser displacement sensor was adopted in the measuring system for advantages of quick data acquisition, high measuring accuracy and no surface scratch. Compared with traditional measuring method by a dial indicator, laser displacement sensor is more appropriate to carry out the measurement on the surface of conical shell. An open CNC system was developed for the measurement. It was based on industry personal computer (IPC) which and took motion control board and data acquisition board as its core. Experiments were conducted on the designed measuring system to find out the factors which influence measuring results. Measuring data showed that measuring results appeared to be a parabolic distribution in the working range of the sensor and the symmetry axis of the parabola was at the middle position. The variation of incident angle has no obvious influence on measuring results.
