6、系實(shí)際的訓(xùn)練,因此,它在我們四年的大學(xué)生活中占有重要的地位就我個(gè)人而言，我希望能通過(guò)這次課程設(shè)計(jì)對(duì)自己未來(lái)將從事的工作進(jìn)行一次適應(yīng)性訓(xùn)練，從中鍛煉自己分析問(wèn)題、解決問(wèn)題的能力，為今后參加祖國(guó)的“四化”建設(shè)打下一個(gè)良好的基礎(chǔ)。由于能力所限，設(shè)計(jì)尚有許多不足之處，懇請(qǐng)各位老師給予指導(dǎo)1攀枝花學(xué)院本科機(jī)械制造工藝學(xué)課程設(shè)計(jì)（論文）零件分析(二)零件的分析1)零件的結(jié)構(gòu)分析由零件結(jié)構(gòu)可以看出，該零件為薄壁圓套類零件。從表面粗糙度和形狀位置精度可以知道，薄壁內(nèi)孔和法蘭面為主要配合面，即為主要加工面。其他面粗加工即可達(dá)到使用要求。為使內(nèi)孔滿足形狀和粗糙度要求必須進(jìn)行半精鏜。法蘭面與內(nèi)孔軸線有
7、垂直度要求，因此在加工時(shí)可以用內(nèi)孔定位加工法蘭面，保證垂直度要求2)零件的工藝分析由該零件需加工的面以及其間有一形狀和定位置要求。分述如下1.以φ240為基準(zhǔn)面加工表面，車孔?20h07車外圓?400h7至?402車止口?340h6至?342以及粗車右端面2.以?240為基準(zhǔn)，車止口?340h7及階面，車外圓?400h73．鉆，對(duì)正畫(huà)線，鉆孔4??16，2?M14?6H底孔以及倒角攻螺紋2攀枝花學(xué)院本科機(jī)械制造工藝學(xué)課程設(shè)計(jì)（論文）工藝規(guī)程設(shè)計(jì)4．銑，口2?20?20?0.025
