0525-JCS-018立式加工中心主軸箱及進(jìn)給系統(tǒng)設(shè)計(jì),jcs,立式,加工,中心,主軸,進(jìn)給,系統(tǒng),設(shè)計(jì) 摘要:本次設(shè)計(jì)通過(guò)對(duì)現(xiàn)有加工中心的分析研究,提出一種新的設(shè)計(jì)方案,其自動(dòng)化程度更高,結(jié)構(gòu)也相對(duì)比較簡(jiǎn)單.這一點(diǎn)在論文會(huì)得以體現(xiàn).本方案中,主軸箱采用交流調(diào)速電機(jī)實(shí)現(xiàn)無(wú)級(jí)變速,在X、Y、Z三個(gè)方向上的進(jìn)給運(yùn)動(dòng)均采用滾珠絲杠,而動(dòng)力則由步進(jìn)電動(dòng)機(jī)通過(guò)調(diào)隙齒輪來(lái)傳遞,并且采用單片機(jī)進(jìn)行數(shù)字控制. 控制系統(tǒng)采用MCS-51系列單片機(jī),通過(guò)擴(kuò)展程序存儲(chǔ)器、數(shù)據(jù)存儲(chǔ)器和I/O接口實(shí)現(xiàn)硬件電路的設(shè)計(jì).論文中也對(duì)軟件系統(tǒng)的設(shè)計(jì)做出了相關(guān)說(shuō)明. 關(guān)鍵詞:交流調(diào)速電機(jī) 滾珠絲杠 步進(jìn)電機(jī) 單片機(jī)系統(tǒng)擴(kuò)展 Abstract: This design tries a new method after the analyze and research of the exited machining center with the higher automatization degrees and the simpler configuration,which will be explained in the paper. In the method, AC adjustable-speed motor is used for the realization of the level shift in variable speed,and in the motion of, we all adopt ball bearing thread haulm for the X、Y、Z direction,The power of which is step by step electromotor transferred by gear that used for adjusting gaps.And more,we used singlechip for numerical control. The control system introduces MCS-51 series singlechip,and the realization of hardware circuit was accomplished by enlarging program memorizer、data memorizer and I/O meet meatus.Also,the paper explained the design for software system. Keywords: AC adjustable-speed motor、ball bearing thread haulm、the step by step electromotor、the enlarge for SCM system 目錄 前言······················································1 1、機(jī)床總體方案設(shè)計(jì)·······································1 1.1 機(jī)床總體尺寸參數(shù)的選定·····························1 1.2 機(jī)床主要部件及運(yùn)動(dòng)方式的選定·······················2 1.3 機(jī)床總體布局的確定·································3 2、主傳動(dòng)的設(shè)計(jì)計(jì)算·······································8 2.1 電機(jī)的選擇·········································8 2.2 齒輪傳動(dòng)的設(shè)計(jì)計(jì)算·································9 2.3 軸的設(shè)計(jì)計(jì)算······································13 2.4 離合器的選用······································21 3、進(jìn)給系統(tǒng)的設(shè)計(jì)計(jì)算···································22 3.1 概述··············································22 3.2 設(shè)計(jì)計(jì)算··········································22 3.3 工作臺(tái)部件的裝配圖設(shè)計(jì)····························29 3.4 滾珠絲杠螺母副的承載能力的校驗(yàn)····················30 3.5 計(jì)算機(jī)械傳動(dòng)系統(tǒng)的剛度····························31 3.6 驅(qū)動(dòng)電動(dòng)機(jī)的選型與計(jì)算····························33 3.7 機(jī)械傳動(dòng)系統(tǒng)的動(dòng)態(tài)分析····························36 3.8 機(jī)械傳動(dòng)系統(tǒng)的誤差計(jì)算與分析·····················37 3.9 確定滾珠絲杠螺母副的精度等級(jí)和規(guī)格型號(hào)············38 3.10 滾珠絲桿副的預(yù)緊方式·····························38 3.11 齒輪傳動(dòng)消隙····································39 4、控制系統(tǒng)的設(shè)計(jì)········································39 4.1 控制系統(tǒng)總體方案的擬訂····························39 4.2 總控制系統(tǒng)硬件電路設(shè)計(jì)····························39 參考文獻(xiàn)·················································56 謝 辭················································57 科技譯文·················································58 vi
