It improved labor productivity and shorten the production time, eliminate human error, the improvement of the machining accuracy and consistency of precision. Though conventional ordinary lathe tool change slowly, low accuracy, low productivity. It cannot adapt to the needs of modern production. Therefore, we must be improved the automatic turret in order to increase productivity, improve product quality and improve working.This rotary tool holder for CNC lathe electrical and mechanical systems related content study, study the composition and working principle of CNC lathes turret and improve the tool changerthe of general machine tools, so that the device has an automatic release, transfer, precision positioning and other functions. This time we should completion of the design of automatic turrets the mechanical parts and electrical parts. Mechanical part is composed of various mechanical calculation and selection of parts, electrical parts is preparation of the turret automatically transfer of the control software, automatic indexing turret. Design of more powerful CNC tool changer, tool changer quickly through the automatic positioning tool can improve the efficiency of CNC lathes and shorten the processing time; while its reliability is more stable, the structure is simpler.Keywords: Automatic turret Tool changer Electro-Mechanical Systems Electrical control目 錄1緒 論11.1自動回轉(zhuǎn)刀架的設(shè)計背景11.2自動回轉(zhuǎn)刀架的市場分析21.3設(shè)計自動回轉(zhuǎn)刀架的意義22自動回轉(zhuǎn)刀架總體設(shè)計32.1總體方案的確定32.2減速機傳動機構(gòu)的確定42.3刀體鎖緊與精定位機構(gòu)的確定52.4抬起機構(gòu)的確定53自動回轉(zhuǎn)刀架機械部分設(shè)計63.1自動回轉(zhuǎn)刀架的工作原理63.2蝸輪及蝸桿的設(shè)計及校核83.2.1蝸桿的選型93.2.2蝸桿副的材料103.2.3按齒面接觸疲勞強度進行設(shè)計103.3蝸輪及蝸桿的主要參數(shù)與幾何尺寸123.4螺桿的主要參數(shù)與幾何尺寸143.4.1螺桿的設(shè)計計算143.5蝸桿軸的設(shè)計153.5.1蝸桿軸的材料選擇，確定許用應(yīng)力153.5.2按扭轉(zhuǎn)強度初步估算軸的最小直徑153.5.3確定各軸段的直徑和長度163.5.4蝸桿軸的校核173.6蝸桿軸的軸承選用214自動回轉(zhuǎn)刀架電氣部分設(shè)計224.1硬件電路設(shè)計224.2控制軟件設(shè)計254.2.180C31單片機及其引腳說明264.2.2 靜態(tài)存儲器6264的特性284.2.3 2764只讀存儲器的特性284.2.4 可編程并行I/O接口芯片8255的特性295結(jié) 論336致 謝347參考文獻35附錄：轉(zhuǎn)配圖A0圖紙一張、零件圖A1、A2各五張（上刀體圖、下刀體圖上圓盤圖、下圓盤圖 、刀架電氣圖、蝸輪、蝸桿圖、螺桿圖、空心軸圖、發(fā)信盤圖）
