非接触式活塞环梯形角测量系统的设计与验证

Design and Verification of Non-Contact Piston Ring Trapezoidal Angle Measurement System

活塞环梯形角是评价活塞环加工质量的关键参数,随着技术与工艺的进步,传统的接触式梯形角测量方案已不能满足现代的生产需求。分析接触式梯形角测量方案存在的问题,提出了基于光谱共焦位移传感器的非接触梯形角测量方案,并从传感器的选型、组合测量头的设计和夹紧机构的设计3个方面展现了全新的测量系统设计方案。通过对测量系统进行误差分析和可行性验证,证明了新的设计方案具有可行性,为研制新型非接触式活塞环梯形角测量仪提供了全新、有效的思路。

The trapezoidal angle of the piston ring is the key parameter to evaluate the machining quality of the piston ring,and with the advancement of technology and technics,the traditional contact trapezoidal angle measurement scheme cannot meet the modern production needs.The problems existing in the contact trapezoidal angle measurement scheme are analyzed,and a non-contact trapezoidal angle measurement scheme based on spectral confocal displacement sensor is proposed,and a new measurement system design scheme is presented from three aspects:sensor selection,combined measuring head design,and clamping mechanism design.Through the error analysis and feasibility verification of the measurement system,the feasibility of the new design scheme is proved,which provides a new and effective idea for the development of the new non-contact piston ring trapezoidal angle measuring instrument.
