.Ccy220 { display:none; } 数控回转工作平台的设计(含 CAD 零件图和装配图)(选题审批表,任务书,开题报告,中期检查表,论文说明书10900字, CAD 图8张) 摘 要：数控车床今后将向中高挡发展，中档采用普及型数控刀架配套，高档采用动力型刀架，兼有液压刀架、伺服刀架、立式刀架等品种，预计近年来对数控刀架需求量将大大增加
但是数控回转工作台更有发展前途,它是一种可以实现圆周进给和分度运动的工作台，它常被使用于卧式的镗床和加工中心上，可提高加工效率，完成更多的工艺，它主要由原动力、齿轮传动、蜗杆传动、工作台等部分组成，并可进行间隙消除和蜗轮加紧，是一种很实用的加工工具
本课题主要介绍了它的原理和机械结构的设计，并对以上部分运用AUTOCAD做图,最后是对数控回转工作台提出的一点建议
关键词：数控回转工作台：齿轮传动：蜗杆传动：间隙消除：蜗轮加紧 Numerical Control Rotary Table Abstract：Numerical control there is in the future lathe to in will develop, the middle-grade to adopt popular numerical control knife rest form a complete set, adopt the motive force type knife rest top-grandly, have such varieties as knife rest of hydraulic pressure, servo knife rest, vertical knife rest, etc. concurrently, it is estimated that it will increase to numerical control knife rest demand greatly in recent years. The development trend of the Numerical control rotary table is: With the development of numerical control lathe, numerical control knife rest begin to change one hundred sheets , electric liquid is it urge and urge direction develop while being servo to make up fast. Some originally design and is it continue electricity to use to four worker location vertical electronic machinery of knife rest mainly- exposed to control system control some designs. And use AUTOCAD to pursue to the above part, have a more ocular knowledge of electronic knife rest. The last proposition has put forward the suggestion and measure to Numerical control rotary table. 〖资料来源：56DOC.COM 毕业设计(论文)网〗 Key words： Numerical control rotary table；Gear drive；Worm drive；Gap elimination； The worm gear steps up. 数控回转工作台的原理与应用 数控机床的圆周进给由回转工作台完成，称为数控机床的第四轴：回转工作台可以与X、Y、Z三个坐标轴联动，从而加工出各种球、圆弧曲线等
回转工作台可以实现精确的自动分度，扩大了数控机床加工范围
[2] 数控回转工作台 数控回转工作台主要用于数控镗床和铣床，其外形和通用工作台几乎一样，但它的驱动是伺服系统的驱动方式
它可以与其他伺服进给轴联动
