油量调节套是VE泵上的一个关键部件。油泵工作时,通过其在柱塞上的轴向位置,调节VE泵的供油量。在加工过程中,能否很好地保证零件端面对基准孔A的跳动要求及尺寸6.5mm的公差要求,是图1保证VE泵性能的关键。油量调节套端面加工的尺寸要求如图1所示。对于平面加工,一般在平面磨床上进行,由于我们采用后续工序在日本进口珩磨机上将两个零件并合一起珩磨中孔,所以对端面质量提出了更高的要求,端面跳动
The fuel regulator is a key component on the VE pump. Pump operation, through its axial position on the plunger, adjust the VE pump fuel supply. In the process of processing, can well ensure that the part of the end face of the reference hole A beating requirements and tolerances of 6.5mm size requirements, Figure 1 is to ensure that the key VE pump performance. Oil regulating sleeve end surface processing size requirements shown in Figure 1. For the plane processing, generally carried out in a surface grinder, as we use the follow-up process in Japan honing machine will be combined with two parts honing the hole, so the quality of the end face put forward higher requirements, face beating
