一、立柱结构 M 4250 A 珩磨机是用来加工大、中型缸体、缸套及其它精密孔的精加工机床(图1)。机床的立柱(图2)是宽高比较大的方柱形细长结构。立柱顶端与主轴变速箱联接,立柱正面设有镶钢导轨、往复油缸、花键轴等。主轴箱在往复油缸作用下沿镶钢导轨作往复运动,同时主轴箱内
First, the column structure M 4250 A honing machine is used to machine large, medium-sized cylinder, cylinder liner and other precision hole finishing machine (Figure 1). The column of the machine tool (Figure 2) is a square columnar slender structure with a large aspect ratio. The top of the column is connected with the transmission of the main shaft, and the front of the column is provided with steel guide rails, reciprocating cylinders, spline shafts and the like. Headstock reciprocating motion along the steel rail under the action of the reciprocating cylinder, at the same time inside the spindle box
