在工业现场,传统的测量方式不能快速准确地测量微小尺寸.基于工业上小尺寸测量的需要,设计了一种可用于测量间隙的光电检测装置.用线阵CCD(Charge Coupled Device)作光电接收传感装置,单片机作主控处理器,对齿轮和高频淬火感应器之间的间隙进行在线非接触测量,取得了较好的测量效果.该方案适用于成本低但测量精度相对要求较高的场合.

At the industrial in-site conditions, the small size can't be quickly and accurately measured by the traditional measurement way. Based on the need for small size measurement in industry, a kind of photoelectric measuring apparatus to clearance is designed in this paper. We use the linear array CCD (Charge Coupled Device) as a photoelectric sensor and singlechip computer as a main control unit to do the non-contact and on-line measurement of clearance between the gear and high-frequency quenching inductor, and get a good measurement result. Therefor, the apparatus can monitor the production status and improve the working efficiency. This project is suitable for the application of low cost and high precision measurement.
