ZHS-UX32自动线用于加工二、四缸两个品种的Ⅰ号泵下体。自动线的总布局见图1。全线按平面方框式布置,共分四段,其中第Ⅰ段与第Ⅲ段是加工工段,每段中均布置了八台加工机床。图2为四缸油泵下体的被加工零件工序图。工件在上线之前必须先加工出上面D、底面H及D面上的2个φ6.7D孔(2个M8的螺纹底孔),H面上的2个φ8D孔,作为上线的工艺基准。图3所示为该线的加工示意图。
ZHS-UX32 automatic line used to process two or four cylinder two varieties of No. I pump body. The overall layout of the automatic line is shown in Figure 1. The whole line is arranged in a square frame and is divided into four sections, of which section Ⅰ and section Ⅲ are processing sections, each of which is equipped with eight processing machine tools. Figure 2 is a four-cylinder pump lower body parts are processed parts process. Workpieces must be machined out of the top D, two φ6.7D holes (two M8 threaded bottom holes) on the bottom H and D sides, and two φ8D holes on the H surface, as a process reference on the line. Figure 3 shows the line processing schematic.
