图1所示的接头零件,在进行φ16mm孔、φ19mm外圆加工时,需组合夹具满足42.4°与12.8°的角度要求。按普通理解,图2所示夹具块的角度组合应能满足要求。为此用SolidWorks进行实体模拟,按图2角度放置零件后,测量显示φ16mm孔中心线与夹具底面不垂直,说明夹具角度不正确。但因实测角度值为89.28°,接近要求的90°,因此在实际 Figure 1 shows the joint parts, in the φ16mm hole, φ19mm cylindrical machining, the combination of fixture required to meet the 42.4 ° and 12.8 ° angle requirements. As is commonly understood, the angle combination of the clamp blocks shown in FIG. 2 should satisfy the requirements. To do this solid modeling with SolidWorks, according to the angle of Figure 2 parts, the measurement shows φ16mm hole centerline and the bottom of the fixture is not vertical, indicating the fixture angle is not correct. However, due to the measured angle value of 89.28 °, close to the required 90 °, so in practice
