中文摘要
隨著科學與技術(shù)的發(fā)展,計算機數(shù)字控制技術(shù)的日趨成熟。加工技術(shù)在世界的工業(yè)范圍內(nèi)都有了顯著的提高。我國由于存在大量的金屬切削機床,把它們?nèi)刻蕴环衔覈鴩?,所以對金屬切削機床進行適當?shù)臄?shù)控化改造,提高生產(chǎn)效率是最明智的選擇。本次設(shè)計是對臺式鉆床的工作臺進行數(shù)控化改造。首先,了解臺式鉆床的結(jié)構(gòu),確定改造方案。其次,選擇滾珠絲杠、步進電機和消隙齒輪等零件,來達到提高傳動精度,減小加工誤差的目的。第三,采用芯片控制代替原有的電氣控制形式,達到提高控制精度、減小響應(yīng)時間和減小占地空間等目的,并且可視化的數(shù)控代碼編程和模擬加工過程,可以提前發(fā)現(xiàn)程序的紕漏。最后,利用PLC可編程控制器對液壓回路等進行控制,方便工程技術(shù)人員編寫和使用。本次設(shè)計的結(jié)果可以順利達到設(shè)計任務(wù)的要求,完成X、Y兩方向單獨運行和同時運行,提高了加工效率。普通機床數(shù)控化改造的技術(shù)可以廣泛的應(yīng)用在機械加工行業(yè)中。工程技術(shù)人員也應(yīng)掌握并創(chuàng)新該項技術(shù)為振興我國機械制造業(yè)而努力。

Abstract
Along with the development of science and technology, the computer numeral control to technically is gradually maturing. The processing technology shows a remarkable progress in the industrial in the world. because of existence a great deal of metal machines in our country , eliminating all of them to not match our country, to carry on an appropriate number control to turn a reformation , and raise working is the most wise choice. This design is numeral control transformation for in table model drills .Firstly, understand the structure that the set table model drills, and make sure a reformation project. Secondly, the choice in Ball bearing guide screw and step-by-step electrical engineering and gear of control gap to attain an accuracy rising, and the purpose of reducing process error. The third, it adopts a chip control to replace original electricity control form, raising control accuracy and reduce the reaction to time and reduce covering space etc. And visual number control procedure code and emulation to process which can discover the error of procedure in advance. In the end, making use of the PLC programmable controller to hydro form etc. and it makes convenient for the engineering technical personnel to write with usage. The result of this design can smoothly attain a request of design and complete X, Y two directions circulate alone and circulate in the meantime and raise working efficiency. The common tool machine number controls technique can extensively be the applied in the manufacturing industry.
Engineering technical personnel should also master and enterprise techniques and make great effort for developing for our country in manufacturing industry.
