一、产品的特点图1为定位盘产品的示意图,规格有多种,型面回转轴线与定位孔轴线相交角度的余角α有28°、30°、32°、34°、36°、38°等,尺寸φA、型面尺寸和偏离定位孔中心位置尺寸α各异。该工件圆弧复合定位型面的精度及三型面之间的位置等分要求高。如何进行 First, the product features Figure 1 is a schematic view of the positioning plate products, there are a variety of specifications, profile axis of rotation and positioning hole axis angle of intersection of the remaining angle α 28 °, 30 °, 32 °, 34 °, 36 °, 38 ° and so on, the size φA, the size of the profile and the position deviation from the center of the positioning hole size α are different. The accuracy of the arc positioning of the workpiece surface and the location of the three types of surface between the high demand. how to proceed
