1、 - 1 - 数控回转工作台设计数控回转工作台设计 - 1 - 摘摘 要要 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

2、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 - 2 - 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 hydraul

3、ic pressure, servo knife rest, vertical knife rest, etc. concurrently, it is estimated that 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

4、 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 Numerica
