专用密封圈及模具检测系统设计

Aiming at the problems of efficient detection of the special sealing ring and the mold cavity parameters，the features of the special sealing ring and the mold, interference factor，error calculation models were researched，the principle and constitution of detection system were summarized，a new detection system based on laser scanning sensor was proposed. The characteristic parameters of the object can be judged by multi section and multi angle scanning the contour of discrete point data and curve fitting. In the detection system，the four-dimensional precision motion platform and high precision three ja'w chuck movement table which form the artifact bearing positioning platform was designed. Then，data acquisition channel was formed by using laser two-dimensional scanning sensor and NI6229 data collection，the establishment and the realization method of the measuring coordinate of the system was analyzed. Finally，the curve fitting and feature extraction algorithm based on the principle of least squares was proposed. The results indicate that the uncertainty of this system can reach 9. 84 μm， and it can effectively solve the problem of the sealing ring and the mold for efficient non-contact detection，so as to improve the quality of sealing ring.
