摘 要
电磁阀体进出油口孔加工组合机床，它的配置型式具有固定式液压夹紧的单工位组合机床，这类组合机床夹具和工作台都是固定不动的，动力滑台实现进给运动。滑台上的动力箱实现切削运动，根据工件结构特点，以及精确要求，采用结合面为定值基准面。 在基准面对应的另一圆柱面上，用压块压紧，由于结合面的加工精度较高，以它为基面，完全可以达到要求的加工精度。
组合机床总体设计三图一卡①“被加工零件工序图”它是组合机床的设计的主要依据，它是制造使用，检修和调整机床的重要技术条件②绘制加工示意图，它是刀具夹具，多轴箱，液压电器装置设计及通用部件选择主要原始资料，它是调整机床，刀具及试车依据。③绘制联系和运动关系及检验机床各部件相对于位置及联系是否满足加工要求，通用部件的选择是否合适，并为进一步开展主轴箱，夹具等专用部件，零件的设计提供依据。④相对生产率计算卡，它用来反映机床的加工过程，完成这一动作所需要的时间，切削用量，机床生产率及机床负荷率。

ABSTRACT
The solenoid valve body turn over oil buccal cavity processing aggregate machine-tool, its configuration has the simplex position aggregate machine-tool which the stationary hydraulic pressure clamps ,this kind of aggregate machine-tool jig and the work table all are fixed motionless, the power realizes for the movement. On power box realization cutting motion, according to the work piece unique feature, as well as the precise request, uses the junction plane for the definite value reduced plane. In the reduced plane correspondence another round cylinder, contracts with the briquetting, because the junction plane processing precision is higher, take it as the basic plane, definitely may meet the requirements the processing precision.
A geometry engine bed system design —- three charts card (1) “is processed the components working procedure chart” it is the aggregate machine-tool design main basis, it makes the use, overhauls and adjusts the engine bed the important engineering factor (2) plan processing schematic drawing, it is the cutting tool jig, the hydraulic pressure electrical fittings design and the general part choice main firsthand information, it is adjusts the engine bed, the cutting tool and the test run basis. (3) The plan relation and the movement relations and the examination engine bed various parts are opposite to the position and relate whether satisfies the processing request, the general part choice is whether appropriate, and for further develops the headstock, the jig and so on the special-purpose part, the components design provides the basis. (4) The generic efficiency computation card, it uses for to reflect the engine bed the processing process, completes the time which this movement needs, the cutting specifications, the engine bed productivity and the engine bed load factor.
Key words: Aggregate machine-tool, hydraulic system, hydraulic cylinder, automatic circulation, headstock.
