摘要
本文是关于双头车床液压系统设计过程的阐述。主要包括系统方案的确定、液压集成块与控制系统的设计和总体布局的设计几个方面的内容。双头车床加工时,由于零件较长,拟采用零件固定,***旋转和进给的加工方式,其加工动作循环方式是:快进→工进→快退→停止,同时要求各个车削头能单独调整。显而易见,采用双头车床能使原需多道工序的产品能一次切削完成,使工序简化,生产效益大大提高。且这种设计所产生的产品对成均匀,精度高。对于双头车床的动力执行部分,本设计采用液压伺服机构。液压伺服机构较其他机构有传动平稳、噪音小、驱动力大等优点,同时也存在漏油、爬行、体积大等缺点。
为了尽量避免液压系统的上述缺点,系统设计时用集成块来代替管路,在液压系统采用液压阀集成配置,可以显著减少管路联接和接头,降低系统的复杂性,增强现场添加和更改回路的柔性,具有结构紧凑、安装维护方便、泄漏少、振动小、利于实现典型液压系统的集成化和标准化等优点。

Abstract
This text is a concerning of hydraulic system of the double-head lathe. In this text ,it primarily includes the determination of hydraulic system  program, the design of the hydraulic manifold block and control system, and the design of the total layout of the contents.
When we use the double-head lathe to work ponents, because they are relatively long, we plan adopt the way ponents fixing, cutting tool revolving and aheading. The circulate pattern of working movement is speeding→aheading→withdrawing→halting. Meanwhile, each turning head is required to adjust solely. Tell its own tale, it can made the produce needed several working procedure formerly pletely only once , predigest the working procedure and improve the manufacture benefit enormously. And the produce manufactured by the design may be symmetry ,uniformity and high precision. For the drive perform part of the double-head lathe ,the design adopts hydraulic pressure servo mechanism. pared to other institutions,it has many advances such as driving calmly, small noise, drive power greatcontemporary, it exists several ings such as leaking oil,creeping big vulume.
In order to avoid the above ings as far as possible,during the design of hydraulic system .I use the hydraulic manifold block to replace the oil that it can use less oil tube and tube joint, plexity of the system, increase the flexibility of appending and altering the system on t
