摘 要
本次畢業(yè)設(shè)計(jì)課題是CJK6032簡易數(shù)控車床。該數(shù)控車床結(jié)夠簡單,緊湊、體積小,功能齊全,是一個(gè)很適用的經(jīng)濟(jì)性數(shù)控車床,能夠達(dá)到非常滿意的工作效率。
CJK6032主要是由傳動(dòng)系統(tǒng),進(jìn)給系統(tǒng)和控制系統(tǒng)三部分組成。對其傳動(dòng)系統(tǒng)設(shè)計(jì)時(shí),先進(jìn)行總體方案的確定,畫出簡易的傳動(dòng)系統(tǒng)圖。再根據(jù)給定的設(shè)計(jì)參數(shù)來確定傳動(dòng)和進(jìn)給系統(tǒng)。滾珠絲杠由步進(jìn)電機(jī)來驅(qū)動(dòng),步進(jìn)電機(jī)由驅(qū)動(dòng)控制系統(tǒng)來驅(qū)動(dòng)。從而實(shí)現(xiàn)進(jìn)給系統(tǒng)的進(jìn)給。通過用途,功能和技術(shù)要求等合理定出系統(tǒng)結(jié)構(gòu),并通過認(rèn)真的計(jì)算得到的參數(shù),然后選擇符合規(guī)定的元件和進(jìn)行系統(tǒng)的結(jié)構(gòu)設(shè)計(jì)。CJK6032是無級調(diào)速的,由電動(dòng)機(jī)加變頻器來實(shí)現(xiàn)。最后通過技術(shù)經(jīng)濟(jì)分析,驗(yàn)證了設(shè)計(jì)生產(chǎn)該產(chǎn)品是經(jīng)濟(jì)合理的。

ABSTRACT
The subject of design is the simple NC CJK6032-lathe. The numerical control lathe simple,compact,small size, fully functional,is a suitable economy of CNC lathes. we can achieve a satisfactory work efficient.
The simple NC CJK6032-lathe is composed of drive system, feed system and controlsystem. When designing drive system, the diagram of simple drive system are specified.Then the drive and feed system are designed according to the given design parameter. Thefeed system is working with the assistance of ball screw. The steped motor drove by deivecontrol system is drove by ball screw. through the use of functional and technical requeirements set reasonable structure,and through careful calculation by the parameters,and then select the required components and systems for the structural design.The simple NC CJK6032-lathe has variable speed which is accomplished by motor and frequency converter. In the end, the analysis on economic prove its reasonable to produce to CJK6032-lathe.
Key words:Lathe;Ball Screw;Stepping motor;Variable Speed;Transmission system
