加工中心的主軸箱設計及橫向進給機構的設計
摘要:本次設計通過對現有加工中心的分析研究,提出一種新的設計方案,其自動化程度更高,結構也相對比較簡單.這一點在論文會得以體現.本方案中,主軸箱采用交流調速電機實現無級變速,在X、Y、Z三個方向上的進給運動均采用滾珠絲杠,而動力則由步進電動機通過調隙齒輪來傳遞,并且采用單片機進行數字控制.
控制系統采用MCS-51系列單片機,通過擴展程序存儲器、數據存儲器和I/O接口實現硬件電路的設計.論文中也對軟件系統的設計做出了相關說明.

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
