Boxtype parts are posed of the box seat, lid, whose structure is relatively plex, usually a number of dimensional accuracy and location of the relatively high precision positioning pin holes, as the relevant parts location or in the process of positioning. Therefore, it is difficult for process workers to design the process and fixture design. This Paper requires that with quality beg development, with benefits seek to live on to store , under the prerequisite of guaranteeing the quality of element processing, have raised productivity and reduced production cost, is one of mainly direction of domestic and international modern machining technology developing. Through knowing and analysis the configuration of the casing part drawing for WH212 gear reducer, so as to analysis the process, make process explanation and analysis the technical requirement and the precision of gear reducer. Then, carry out the design of clamping apparatus and analysis the precision and error for the processing of bearing hole and the base hole of the casing of gear reducer, this technology and the design result of clamping apparatus can apply in production requirement. Key words: gear reduce。 fixed position。 ......................................................................................... 5 毛坯的形狀及尺寸的確定: .......................................................................... 5 毛坯的材料熱處理 .......................................................................................... 6 減速機箱體的主要技術要求 .................................................................................. 6 減速機箱體的機械加工工藝過程 .......................................................................... 7 零件圖分析 .............................................................................................................. 8 減速機加工的 工藝路線 .......................................................................................... 8 加工方法的選擇 .............................................................................................. 8 加工階段的劃分 .............................................................................................. 9 工序的集中與分散 ........................................................................................ 10 加工順序的安排 ............................................................................................ 10 第三章 定位基準的選擇 ................................................................................................ 14 粗基準的選擇 ........................................................................................................ 14 精基準的選擇 ........................................................................................................ 14 第四章 加工余量和工序尺寸的確定 ............................................................................ 16 加工余量的確定 .................................................................................................... 16 尺寸鏈的計算 ........................................................................................................ 16 第五章 夾具設計概述 .................................................................................................... 18 機床夾具的概念 .................................................................................................... 18 目 錄 Ⅱ 機床夾具的分類 .................................................................................................... 18 機床夾具的作用 .................................................................................................... 18 機床夾具設計過程 ................................................................................................ 18 減速機箱體夾具設計 ............................................................................................ 19 第六章 鉆床夾具設計 .................................................................................................... 20 設計任務分析 ........................................................................................................ 20 設計方案論證 ........................................................................................................ 20 切削力及夾緊力的計算 ........................................................................................ 20 設計及操作的簡要說明 ........................................................................................ 21 結構分析 ............................................................................................................
