Abstract The main contents of the curriculum design, including the processing of aircraft bearings process design and drilling holes Ф30 dedicated fixture design. First of all, through the analysis of aircraft bearings, to understand the role of aircraft bearings. Second, based on rough pieces of aircraft bearings and production requirements of the Program and the parison processing pro gram to develop a practical point of order processing bearing frame line. Reuse of machinery and other manufacturing technologyrelated courses based on knowledge, determine the bearing frame in the processing of the positioning, clamping and the process line and to determine the level of the processing technology of surface size and select the appropriate machine tool and tool to ensure the quality of parts machining . Finally, parts are processed in accordance with the processing requirements of machine tool fixture design reference manual and related to the use of surface fixture design books, the basic principles and methods, fixture design program to develop design efficient, laborsaving, economic rationality and processing to ensure the quality of th e fixture. Throughout the curriculum design process was pleted parts map, blank map of the specific folder and the folder assembly mapping specific parts. 目 錄 1 零件的分析 ................................... 1 軸承架的作用 ............................ 1 軸承架的技術(shù)要求 ........................ 1 審查軸承架的工藝性 ....................... 2 2 軸承架毛坯的確定 .............................. 2 確定軸承架的生產(chǎn)類型 ..................... 2 確定毛坯的類型和制造方法 .................. 3 3 擬定工藝路線 .................................. 3 定位基準(zhǔn)的選擇 ........................... 3 確定各表面的加工方法 ..................... 4 加工階段的劃分 ........................... 4 工藝線路方案 ............................. 4 確定各工序的加工余量 ..................... 5 4 Ф30 Ф35 孔切削用量的計(jì)算 ..................... 7 鉆孔工步切削用量的計(jì)算 ................... 7 擴(kuò)孔工步切削用量的計(jì)算 ................... 8 5 加工 Ф30 孔基本工時(shí)的計(jì)算 ..................... 8 基本時(shí)間的計(jì)算 ........................... 8 輔助時(shí)間的確定 .......................... 8 其他時(shí)間的計(jì)算 ........................... 8 單件時(shí)間定額 djt ........................... 9 編制工序卡片 ............................. 9 6 Ф 30 孔專用夾具設(shè)計(jì) ........................... 9 定位方案的設(shè)計(jì) ........................... 9 定位誤差分析與計(jì)算 ...................... 10 導(dǎo)向元件的設(shè)計(jì) .
