在机床夹具设计中,对于工件的端面或圆柱表面的加工,通常以圆柱孔及其垂直平面作定位基准,在轴孔中定心的是圆柱定位销,其高度过去主要是凭经验确定。这样有时会出现定位销卡往、破裂或使工件内孔擦伤等现象。
In the design of machine tool fixtures, the machining of the end surface or the cylindrical surface of the workpiece usually takes the cylindrical hole and its vertical plane as the positioning datum. The centering of the shaft hole is a cylindrical locating pin whose height has mainly been empirically determined in the past. This will sometimes appear to locate the pin to crack, or make the workpiece within the hole scratches and so on.
