如附图1及附图2所示，数控车床的主轴10的端面为了装配方便，通常设计成锥端11，如附图1及附图2所示。由于主轴是精密部件，其精度要求高，因此，也需要进行精密的测量。图中锥端11处的大端尺寸Φd1是锥面与平面相交的一个空间尺寸，无法直接测量得到，常用的方式为三坐标测量以及利用环规和塞尺配合测量，并进行相关计算。As shown in the accompanying drawings 1 and 2, the end surface of the spindle 10 of the CNC lathe is usually designed as a tapered end 11 for the convenience of assembly, as shown in the accompanying drawings 1 and 2. Since the spindle is a precision component with high accuracy requirements, it also requires precise measurement. The large-end dimension Φd1 at the cone end 11 in the figure is a spatial dimension where the cone surface intersects with the plane and cannot be directly measured. Commonly used methods are three-coordinate measurement and the use of ring gauges and feeler gauges to measure together and perform related calculations.
但利用环规和塞尺配合测量时，由于塞尺的厚度是定值系列化，经常出现间隙值无合适厚度的塞尺规格来测量，因此，测量的间隙值不够精确，并且尺寸Φd1是通过间隙值计算，测量的间隙值可能需要多个厚度规格塞尺叠加，间隙值需要计算才能得到，不能直接读取，不直观。However, when using a ring gauge and a feeler gauge to measure together, since the thickness of the feeler gauge is a series of fixed values, the gap value often does not have a feeler gauge specification of appropriate thickness to measure. Therefore, the measured gap value is not accurate enough, and the size Φd1 is measured by To calculate the gap value, the measured gap value may require the superposition of multiple thickness specification feeler gauges. The gap value needs to be calculated to obtain, and cannot be read directly, which is not intuitive.
