This design is prehensively applied the knowledge of correlated curriculum such as engineering graphic, mechanical design, mechanical manufacturing, engineering and mechanical geometry precision design. This graduation design detailed analysis process of rocker shaft pedestal. Process what is in keeping with technical requirements is selection through paring and analyzing process scheme, to obtain the machinery process card and mechanical processes card. This design designed boring fixture of rocker shaft pedestal, expounds about the positioning scheme selection, determine the clamping schemes. Boring mould design and fixture pedestal design. Use AutoCAD pleted the assembly of this special fixture and part drawing of fixture base. In addition, the 3D modeling designs of the part of the rocker shaft pedestal. 【 Key Words】 Parts processing， Process flow， Internal boring， Dedicated fixture， CAD , 浙江大學(xué)城市學(xué)院畢業(yè)論文 目錄 III 目錄 第 1 章 緒論 ............................................................................................................................1 制工藝與夾具設(shè)計的發(fā)展概況 ................................................................................1 機(jī)制工藝與夾具設(shè)計相關(guān)技術(shù)的國內(nèi)外現(xiàn)狀 ........................................................1 選題意義和關(guān)鍵 問題 ................................................................................................2 選題的背景 ....................................................................................................2 選題意義 .........................................................................................................2 關(guān)鍵問題 .........................................................................................................3 第 2 章 機(jī)械加工工藝與夾具設(shè)計概述 ................................................................................4 機(jī)械加工工藝過程中的基本概念 ...........................................................................4 機(jī)械加工工藝規(guī)程設(shè)計的基本準(zhǔn)則 ........................................................................4 機(jī)床夾具概述 ............................................................................................................6 工件在夾具中的定位 .............................................................................................7 工件在夾具中的夾緊 ................................................................................................7 第 3 章 搖桿軸支座機(jī)械加工工藝規(guī)程設(shè)計 ........................................................................9 零件的圖紙與工藝分析 ............................................................................................9 零件的作用 .....................................................................................................9 零件的工藝分析 .............................................................................................9 工藝規(guī)程定性設(shè)計 ..................................................................................................10 生產(chǎn)類型與毛坯制造方法的確定 ...............................................................10 定位基準(zhǔn)的選擇 ...........................................................................................10 工藝路線的擬定 ........................................................................................... 11 工藝規(guī)程定量設(shè)計 ..................................................................................................13 機(jī)械加 工余量、工藝尺寸及毛坯尺寸的確定 ...........................................13 切削余量及基本工時的確定 .......................................................................14 搖桿軸支座機(jī)械加工工藝過程 ...........................................................................18 搖桿軸支座機(jī)械加工工藝過程卡 ...............................................................19 搖桿軸支座機(jī)械加工工序卡 .......................................................................20 第 4 章 搖桿軸支座專用鏜孔夾具設(shè)計 ............................................................................31 鏜夾具的結(jié)構(gòu)形式與設(shè)計要點。 ..........................................................................31 鏜床夾具的典型結(jié)構(gòu)形式 ...........................................................................31 鏜床夾具的設(shè)計要點 ...................................................................................31 浙江大學(xué)城市學(xué)院畢業(yè)論文 目錄 IV 搖桿軸支座專用鏜孔夾具總體結(jié)構(gòu)方案 ..............................................................32 定位元件與夾緊裝置的設(shè)計 ..................................................................................33 定位元件 ......................................................................................................33 夾緊裝置的設(shè)計 ...........................................................................................33 鏜模與夾具體的設(shè)計 ..............................................................................................34 夾具工作能力的計算 ..............................................................................................36 使用操作說明 ..........................................................................................................38 第 5 章
