现有的刃口轮廓测量仪是由带斜棱定位器的铰接双臂杆、标记器和记录纸带组成。为了提高测量精度及能够同时测定犁铧刃口在磨损过程中的角度和线性参数,对该仪器进行了一些改进。在标记器部分增加了固定绘图板用的导向板;在探尺部 The existing edge profiler consists of a hinged double-arm bar with bevel locator, marker and recording tape. In order to improve the measurement accuracy and the simultaneous determination of the angle and linear parameters of plowshare in the process of wear, some improvements have been made to the instrument. In the marker part adds a fixed drawing board with the guide plate; in the probe part
