立式加工中心主軸箱設(shè)計【含CAD圖紙、說明書】

i摘要:本次設(shè)計通過對現(xiàn)有加工 中心的分析研究,提出一種新的設(shè)計方案,其自動化程度更高,結(jié)構(gòu)也相對比較簡單.這一點(diǎn)在論文會得以體現(xiàn).本方案中,主軸箱采用交流調(diào)速電機(jī)實(shí)現(xiàn)無級變速,在 X、Y、Z 三個方向上的進(jìn)給運(yùn)動均采用滾珠絲杠,而動力則由步進(jìn)電動機(jī)通過調(diào)隙齒輪來傳遞,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),通過擴(kuò)展程序存儲器、數(shù)據(jù)存儲器和I/O 接口實(shí)現(xiàn)硬件電路的設(shè)計.論文中也對軟件系統(tǒng)的設(shè)計做出了相關(guān)說明.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iiAbstract: 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 systemiii目錄前言11、機(jī)床總體方案設(shè)計11.1 機(jī)床總體尺寸參數(shù)的選定11.2 機(jī)床主要部件及運(yùn)動方式的選定21.3 機(jī)床總體布局的確定32、主傳動的設(shè)計計算82.1 電機(jī)的選擇iv82.2 齒輪傳動的設(shè)計計算92.3 軸的設(shè)計計算132.4 離合器的選用213、進(jìn)給系統(tǒng)的設(shè)計計算223.1 概述223.2 設(shè)計計算223.3 工作臺部件的裝配圖設(shè)計29v3.4 滾珠絲杠螺母副的承載能力的校驗(yàn)303.5 計算機(jī)械傳動系統(tǒng)的剛度313.6 驅(qū)動電動機(jī)的選型與計算333.7 機(jī)械傳動系統(tǒng)的動態(tài)分析363.8 機(jī)械傳動系統(tǒng)的誤差計算與分析373.9 確定滾珠絲杠螺母副的精度等級和規(guī)格型號383.10 滾珠絲桿副的預(yù)緊方式383.11 齒輪傳動消隙394、控制系統(tǒng)的設(shè)vi計394.1 控制系統(tǒng)總體方案的擬訂394.2 總控制系統(tǒng)硬件電路設(shè)計39參考文獻(xiàn)56謝 辭57 科技譯文58
