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、機床總體方案設計·······································1 1.1 機床總體尺寸參數的選定·····························1 1.2 機床主要部件及運動方式的選定·······················2 1.3 機床總體布局的確定·································3 2、主傳動的設計計算·······································8 2.1 電機的選擇·········································8 2.2 齒輪傳動的設計計算·································9 2.3 軸的設計計算······································13 2.4 離合器的選用······································21 3、進給系統(tǒng)的設計計算···································22 3.1 概述··············································22 3.2 設計計算··········································22 3.3 工作臺部件的裝配圖設計····························29 3.4 滾珠絲杠螺母副的承載能力的校驗····················30 3.5 計算機械傳動系統(tǒng)的剛度····························31 3.6 驅動電動機的選型與計算····························33 3.7 機械傳動系統(tǒng)的動態(tài)分析····························36 3.8 機械傳動系統(tǒng)的誤差計算與分析·····················37 3.9 確定滾珠絲杠螺母副的精度等級和規(guī)格型號············38 3.10 滾珠絲桿副的預緊方式·····························38 3.11 齒輪傳動消隙····································39 4、控制系統(tǒng)的設計········································39 4.1 控制系統(tǒng)總體方案的擬訂····························39 4.2 總控制系統(tǒng)硬件電路設計····························39 參考文獻·················································56 謝 辭················································57 科技譯文·················································58 vi
