I畢業(yè)設計(論文)題 目： 自動攻絲機設計 摘 要本文主要進行的是自動攻絲機設計，該自動攻絲機在普通的小臺式鉆床機床上進行設計，設計機床得主傳動變速系統(tǒng)時首先利用傳動系統(tǒng)設計方法求出理想解和多個合理解。根據(jù)數(shù)控機床主傳動系統(tǒng)及主軸功率與轉矩特性要求，分析了機電關聯(lián)分級調(diào)速主傳動系統(tǒng)的設計原理和方法。從主傳動系統(tǒng)結構網(wǎng)入手，確定最佳機床主軸功率與轉矩特性匹配方案，計算和校核相關運動參數(shù)和動力參數(shù)。本說明書著重研究機床主傳動系統(tǒng)的設計步驟和設計方法，根據(jù)已確定的運動參數(shù)以變速箱展開圖的總中心距最小為目標，擬定變速系統(tǒng)的變速方案，以獲得最優(yōu)方案以及較高的設計效率。在機床主傳動系統(tǒng)中，為減少齒輪數(shù)目，簡化結構，縮短軸向尺寸，用齒輪齒數(shù)的設計方法是試算，湊算法，計算麻煩且不易找出合理的設計方案。本文通過對主傳動系統(tǒng)中三聯(lián)滑移齒輪傳動特點的分析與研究，繪制零件工作圖與主軸箱展開圖及剖視圖。關鍵詞：分級變速;傳動系統(tǒng)設計;傳動副;結構網(wǎng);結構式;齒輪模數(shù); 傳動比IIIAbstractFirst, in order to obtain the ideal and more understanding of the design method of transmission system design of machine tool transmission system when the winner. According to the requirements of the main drive system of CNC machine tool and spindle power and torque characteristics, analysis of the design principle and method of mechanical and electrical connection and speed of main transmission system. Starting from the main drive system structure network, determine the optimum matching scheme of machine tool spindle power and torque characteristics, the calculation and verification of relevant motion parameters and dynamic parameters. Design steps and design method of this specification focuses on the main drive system of machine tool, according to the motion parameters have been determined by transmission center distance of expansion graph of the minimum as the goal, formulate transmission scheme transmission system, in order to obtain the optimal scheme and high design efficiency. In the main drive system of machine tool, in order to reduce the number of gears, simplify the structure, reduce the axial size, design method of the number of gear teeth is trial, join algorithm, design calculation of trouble and is not easy to find a reasonable. Through the research and analysis of the main drive system of triple slide gear characteristics, draw the part drawing and the spindle box expansion plan and section view.Key Words: classification of transmission; the transmission system; design; transmission; network structure; structure type; the module of gear; transmission ratio4目 錄摘 要 IIAbstract.III1 緒論.11.1 鉆床簡介 11.2 鉆床的發(fā)展及趨勢 11.3 自動攻絲機介紹 21.4 本課題設計內(nèi)容及要求 32 自動攻絲機總體方案設計.42.1 自動攻絲機的動力選擇 42.2 自動攻絲機的驅(qū)動方式 42.3 自動攻絲機的動力性能比較 52.4 自動攻絲機動力的計算與選擇 63 自動攻絲機設計.83.1 運動參數(shù)及轉速圖的確定 83.1.1 轉速范圍 .83.1.2 轉速數(shù)列 .83.1.3 確定結構式 .93.1.4 確定結構網(wǎng) .93.1.5 繪制轉速圖和傳動系統(tǒng)圖 .103.2 確定各變速組此論傳動副齒數(shù) 104 自動攻絲機動力計算.124.1 帶傳動設計 124.2 計算轉速的計算 134.3 齒輪模數(shù)計算及驗算 144.4 常用材料及熱處理 1454.5 傳動軸最小軸徑的初定 194.6 主軸合理跨距的計算 205 主要零部件的選擇.225.1 軸承的選擇 225.2 鍵的規(guī)格 225.3 變速操縱機構的選擇 226 校核.236.1 剛度校核 236.2 軸承壽命校核 247 結構設計及說明.267.1 結構設計的內(nèi)容、技術要求和方案 267.2 展開圖及其布置 26結 論.27參考文獻.28致 謝.29
