一、测量线路的工作原理泰吕朗“73”型圆度仪的电气部分包括电气箱和4型参考计算机。它的工作原理是:通过主轴的旋转带动测量杆围绕工件作径向运动,由电感式传感器变为电讯号。此讯号经电桥和1KC振荡讯号调制后(图1)送入放大器放大,再由滤波器滤去1KC振荡讯号及不需要的高频讯号,检出的电讯号再送入计算机和记录器进行不圆度和不同心度计算、读数和记录曲线。 First, the working principle of the measuring line Tyrolean “73” roundness of the electrical part includes the electrical box and 4 reference computer. Its working principle is: Driven by the spindle rotation of the measuring rod around the workpiece for radial movement, from inductive sensors into electrical signals. This signal is modulated by the bridge and 1KC oscillation signal (Figure 1) into the amplifier, and then filtered by the filter 1KC oscillation signal and unwanted high-frequency signal, the detected signal sent to the computer and the recorder do not Circularity and eccentricity calculations, readings and recording curves.
