摘 要
數(shù)控車床今后將向中高擋發(fā)展,中檔采用普及型數(shù)控刀架配套,高檔采用動力型刀架,兼有液壓刀架、伺服刀架、立式刀架等品種,預(yù)計近年來對數(shù)控刀架需求量將大大增加。但是數(shù)控回轉(zhuǎn)工作臺更有發(fā)展前途,它是一種可以實現(xiàn)圓周進給和分度運動的工作臺,它常被使用于臥式的鏜床和加工中心上,可提高加工效率,完成更多的工藝,它主要由原動力、齒輪傳動、蝸桿傳動、工作臺等部分組成,并可進行間隙消除和蝸輪加緊,是一種很實用的加工工具。本課題主要介紹了它的原理和機械結(jié)構(gòu)的設(shè)計,并對以上部分運用AUTOCAD做圖,最后是對數(shù)控回轉(zhuǎn)工作臺提出的一點建議。

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.
