Design and Verification of Non-Contact Piston Ring Trapezoidal Angle Measurement System
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 trapezoid-al 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 de-sign scheme is proved,which provides a new and effective idea for the development of the new non-contact pis-ton ring trapezoidal angle measuring instrument.
