1、XK5040數(shù)控立式銑床及控制系統(tǒng)設計85摘要數(shù)控機床即數(shù)字程序控制機床,是一種自動化機床,數(shù)控技術是數(shù)控機床研究的核心,是制造業(yè)實現(xiàn)自動化、網(wǎng)絡化、柔性化、集成化的基礎。隨著制造技術的發(fā)展,現(xiàn)代數(shù)控機床借助現(xiàn)代設計技術、工序集約化和新的功能部件使機床的加工范圍、動態(tài)性能、加工精度和可靠性有了極大的提高。本文主要對XK5040數(shù)控立式銑床及控制系統(tǒng)進行設計,首先分析立式銑床的加工特點和加工要求確定其主參數(shù),包括運動和動力參數(shù);根據(jù)主參數(shù)和設計要求進行主運動系統(tǒng)、進給系統(tǒng)和控制系統(tǒng)硬件電路設計。主要進行主運動系統(tǒng)和進給系統(tǒng)的機械結構設計及滾珠絲杠和步進電機的選型和校核;對于控制系
2、統(tǒng)由于這里主要針對經(jīng)濟型數(shù)控銑床的設計,這里采用步進電機開環(huán)控制,計算機系統(tǒng)采用高性能價格比的MCS-51系列單片擴展系統(tǒng),主要進行中央處理單元的選擇、存儲器擴展和接口電路設計。由于本文采用8031單片機控制系統(tǒng),因此,設計出的立式銑床性能價格比高,滿足經(jīng)濟性要求??蓪嵱糜诩庸ぞ容^高的場合。關鍵詞數(shù)控技術;立式銑床;設計85ABSTRACTThenumericalcontrolenginebedisthedigitalprocesscontrolenginebed,isonekindofautomatedenginebed,thenumericalcontroltechnol
