1、摘 要 液压传动技术虽然较为年轻，但几十年在中国有了充足的发 展，技术越来越成熟，其市场前景也让人惊叹。 本文主要研究设计节流调速回路设计及钻床动力滑台工作循 环的微机控制。 在参考大量资料之后主要研究了该组合机床系统的 运动循环， 并对该机床的液压系统方案的敲定作出了详细的论述分 析；然后对机床系统的负载分析做了详细的计算和验算；再对该机 床的液压缸、 液压油箱以及各类液压元件及其辅助元件作了充分的 计算、设计以及选取；本设计的主要特色在于所设计组合机床在液 压传动系统的支持下能在工件被夹紧后同时在两面对工件进行钻 孔，使机床的效率较传统同类机床有很大的提升，使之创造出更多 的价值。 立式动

2、力滑台所加工的孔，光洁度和尺寸精度要求较高，换 向精度要求也较高。 而第二次慢速工进是为了满足扩锥孔的进给量 要求。由此可确定滑台动作顺序为：快进工进工进快退 至原位停止。 在我们所学的机床中，节流调速回路主要应用于钻孔专用组 合机床上。钻孔专用组合机床一般用于加工垂直孔和水平孔。 二次节流调速回路应用在钻孔专用机床上， 是用于控制机床的 滑台的动作，从而达到钻孔时两次工进的目的。 关键词：关键词：液压传动；系统控制；液压回路 ABSTRACT ABSTRACT Hydraulic transmission technology, while relatively young, but for

6、chine tool than the traditional kind have greatly improved, so create more value. The processing power sliding table vertical holes, finish and dimensional accuracy are higher, and for the precision is high. The second slow work progress to meet the expanding cone of feed requirements. Slide action can be determined order: fast-forward workers into work quickly retreat into the in situ stop. In our study of machine tools, the cutting speed control circuit is mainly used in dr
