Design and Application of Non-Contact Measuring System for Cylindricity Error of Large Rotary Parts
[Purposes]In order to solve the problems such as difficult measurement and inconvenient sam-pling of form and position error of large rotary parts,a suitable non-contact measurement system is de-signed for cylindricity error of large rotary parts.[Methods]Using STM32 single chip microcomputer as the main controller,the positioning clamping device and laser displacement sensor are designed to real-ize non-contact measurement.The distance information collected is processed and analyzed by Lab-VIEW software platform.Meanwhile,the cylindricity error display interface is designed so that users can visually view the measurement results.[Findings]The measuring device can measure the cylindricity er-ror of large rotary parts,and the display interface can display the contour state of the measuring section in real time,and automatically display the calculated cylindricity error value.As you input the cylindric-ity tolerance value of the part in the panel,the corresponding indicator will light up when the measured error value exceeds its tolerance value.[Conclusions]The system solves the demand of non-contact measurement of large rotary parts well,and has good application value and application prospect.
