组合机床主轴箱孔的位置精度直接决定着工件孔的位置精度,这给主轴箱体的加工带来很大困难。为此,我们采用了镶嵌主轴箱,取得了理想效果。所谓镶嵌主轴箱就是把主轴箱的主轴承孔,做成轴承座,镶嵌在箱体上,这些轴承座在箱体上的位置可以调整,使之达到最理想的精度。主轴箱调整好后,将轴承座紧固死并配钻铰稳销孔,装入稳销。镶嵌主轴箱的结构见附图。为保证 The position accuracy of the combined machine tool spindle box hole directly determines the position accuracy of the workpiece hole, which brings great difficulties to the machining of the spindle box. For this reason, we have adopted the mosaic headstock, and achieved the ideal result. The so-called mosaic spindle box is the main bearing box spindle hole, made of bearing seat, inlaid in the box, the bearing seat on the box position can be adjusted to achieve the best accuracy. After the adjustment of the spindle box, the bearing seat is tightened with dead-end and pin hole steady sales, into the steady sales. Inlaid spindle box structure shown in the drawings. To guarantee
