【正文】 摘要I摘 要 本次設(shè)計是對轉(zhuǎn)向節(jié)的加工工藝規(guī)程及一些工序的專用夾具設(shè)計。轉(zhuǎn)向節(jié)零件的主要加工表面是轉(zhuǎn)向節(jié)軸表面，端面，主銷孔及鍵槽加工。那么一個良好的工藝安排以及專用夾具的設(shè)計必不可少。同時夾具的設(shè)計也要考慮拆卸的方便及安全。所以分析問題是解決問題的關(guān)鍵。來尋求一個最好的方案。關(guān)鍵詞 轉(zhuǎn)向節(jié)，加工工藝，專用夾具 ABSTRACTIIABSTRACTThe design of the steering knuckle of the processing order of the processes and some special fixture design. Steering knuckle parts of the main surface is a knuckle spindle surface, surface, the main pin hole and keyway. By the principle known processing, in order to ensure the accuracy of the parts, at the same time, save cost shorten the processing cycle to improve production efficiency. So a good process arrangement and special fixture design essential. In the process of arrangement is not tight reasonable processing requirements, but also consider the operator and processing machinery safety. At the same time the fixture design also consider removing the convenience and safety. The design of a good tooling arrangement route must to process a detailed analysis and careful consideration can reach. So the analysis of a problem is the key. At the same time, repeated adjustment. To seek a better solution. In order to ensure the machining precision of the workpiece and the production rhythm.Key words ： Steering knuckle ,Process of the craft,special fixture 目 錄1目 錄摘 要 ..........................................................................................................................ⅠABSTRACT.................................................................................................................II目錄 ................................................................................................................................11 緒 論 .........................................................................................................................12 轉(zhuǎn)向節(jié)加工工藝規(guī)程設(shè)計 ......................................................................................3 零件的分析 .............................................................................................................................3 零件的作用 .....................................................................................................................3 零件的工藝分析 .............................................................................................................3 工藝過程設(shè)計所應(yīng)采取的相應(yīng)措施 .....................................................................................4 轉(zhuǎn)向節(jié)加工定位基準(zhǔn)的選擇 ................................................................................................4 確定毛坯的制造形式 ....................................................................................................4 粗基準(zhǔn)的選擇 .................................................................................................................4 精基準(zhǔn)的選擇 .................................................................................................................5 工藝路線的制定 ....................................................................................................................5 工藝方案一 ....................................................................................................................5 工藝方案二 ....................................................................................................................6 工藝方案的比較與分析 ................................................................................................6 機(jī)械加工余量、工序尺寸及毛坯尺寸的確定 .....................................................................6 確定切削用量及基本工時（機(jī)動時間） .............................................................................8 時間定額計算及生產(chǎn)安排 ...................................................................................................23 本章小結(jié) ..............................................................................................................................263 拉削轉(zhuǎn)向節(jié) 216。41 主銷孔夾具設(shè)計 .......................................................................................27 定位方案的分析和定位基準(zhǔn)的選擇 ...................................................................................27 拉削力與夾緊力計算 ...........................................................................................................28 底座設(shè)計 ...............................................................................................................................28 夾具精度分析 .......................................................................................................................28 目 錄2 本章小結(jié) ...............................................................................................................................294 鉆 及 4216。16 夾具設(shè)計 .............................................................................................30 定位方案的分析和定位基準(zhǔn)的選擇 ...................................................................................30 鉆削力與夾緊力計算 ...........................................................................................................31 型塊與本體的設(shè)計 ............................................................................................................31 夾具精度分析 .......................................................................................................................32 本章小結(jié) ...............................................................................................................................32.........................................................................................................................................................5 銑主銷孔外側(cè)面夾具設(shè)計 .......................................................................................33 銑主銷孔外側(cè)面夾具設(shè)計 ...................................................................................................33 定位方案的分析和定位基準(zhǔn)的選擇 ...................................................................................33 銑削力與夾緊力計算 .....................................................
