对于机床、柴油机,拖拉机的箱体类零件,常常会碰到两孔不同轴度误差的测量问题。当没有专用量具时,测量可在平台上用通用工量具进行,其中等高打表法用的较多,现简介如下: 一、对基准轴心线不同轴度误差的测量如图1所示,零件用可调支承(千斤顶)支承在平板上,基准孔(左孔)和被测孔(右孔)插入合适的心轴,然后打表测量。测量时,首先调整基准孔两端点与平板等高
For machine tools, diesel engines, tractor box parts, often encounter two holes of different axis error measurement problems. When there is no special gage, the measurement can be carried out on the platform with universal measuring tools, including the use of contour table more, are as follows: First, the reference axis of the axis of measurement of different axial errors shown in Figure 1 The part is supported on a flat plate with an adjustable support (jack). The reference hole (left hole) and the hole to be measured (right hole) are inserted into the appropriate spindle, and then the watch is measured. Measurement, the first adjustment of both ends of the reference hole and the plate contour
