液压系统在组合机床上的应用 摘 要 液压以其独特的优点在机械设计中占有重要地位。它以通用部件为基础，根据工件加工需要，配以少量的专用部件组成一种机床，它具有低成、高效率的优点。以现在的发展趋势来看，液压车床的多工位加工如果加入柔性系统则发展成今天的加工中心。在今天的发展趋势中，一台液压车床如果不能完成全部的工艺过程，这时往往把几台机床布置成流水线，大大缩短了加工时间。而液压系统在组合机床上的应用更使其呈现出了新的春天。液压传动的优点很多：在同等的体积下液压装置能比电气产生更大的动力：液压装置工作比较平稳；液压装置能在大范围内实现无级调速，它还可以在运转中进行调速；液压传动易于对液体压力、流量或流动方向进行调节或控制；液压装置易于实现过载保护；液压元件实现了标准化、系列化和通用化；用液压传动实现直线运动比用机械传动简单。液压； 液压缸，液压油箱The abstract hydraulic pressure occupies important position with its unique merit in machinery design. It takes the component being applied or used universally as basis , basis workpiece treating needs, match it with a little special-purpose component composition one kind of machine tool , its have low Cheng , high efficiency merit. Regarding developing trend now, hydraulic pressure develops the treating centre becoming today if adding flexibility system the lathe multistation treating. In developing trend today, one hydraulic pressure lathe accomplishes all procedure if unable, at this time sometimes have arranged several machine tools to become a production line , curtailing greatly to process time. But, the systematic hydraulic pressure application on combination machine tool has made the person display new spring more. The hydraulic drive merit many: Driving force that the hydraulic pressure device can under equal volume are bigger than electric creation: Hydraulic pressure device job comparison is stable; The hydraulic pressure device can realize stepless speed regulating within big range , it can carry out speed regulation in the travel; Hydraulic drive is prone pressure , rate of flow or mobile direction to carry out adjustment on liquid or control; The hydraulic pressure device is apt to be realized overload protection; The hydraulic pressure component has realized normalizing , be seriated and be applied or used universally-rization; Using hydraulic drive to realize linear motion is simpler than using mechanical drive.
