K061-杠桿(一)機(jī)械加工工藝規(guī)程及鉆20H7孔夾具設(shè)計(jì),k061,杠桿,機(jī)械,加工,工藝,規(guī)程,20,h7,夾具,設(shè)計(jì) 遼寧工程技術(shù)大學(xué)課程設(shè)計(jì)III遼寧工程技術(shù)大學(xué)課 程 設(shè) 計(jì)題 目：設(shè)計(jì)“杠桿”零件加工工藝規(guī)程及鉆削20H7孔工序?qū)Ｓ脢A具班級(jí)： 機(jī)SX05-1 姓名： 石子銅 指導(dǎo)教師： 張興元 完成日期： 2008-06-29 摘要機(jī)械制造技術(shù)基礎(chǔ)課程設(shè)計(jì)是我們學(xué)完了大學(xué)的全部基礎(chǔ)課、技術(shù)基礎(chǔ)課以及大部分專業(yè)課之后進(jìn)行的.這是我們?cè)谶M(jìn)行畢業(yè)設(shè)計(jì)之前對(duì)所學(xué)各課程的一次深入的綜合性的總復(fù)習(xí),也是一次理論聯(lián)系實(shí)際的訓(xùn)練,得到解決問題和分析問題能力的初步培養(yǎng)，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，我希望能通過這次課程設(shè)計(jì)對(duì)自己未來將從事的工作進(jìn)行一次適應(yīng)性訓(xùn)練，從中鍛煉自己分析問題、解決問題的能力，為今后參加祖國的“四化”建設(shè)打下一個(gè)良好的基礎(chǔ)。 AbstractAfter the machine manufacture technology base curriculum project was we studies universitys complete basic course, the technical basic course as well as the majority of professional courses, carried on. This is we before carrying on the graduation project to studies various curricula a thorough comprehensive total review, is also a apply theory to reality training, is solved the problem and the analysis question ability preliminary raise, therefore, it holds the important status in we four year university life.To my own opinion, I hoped that can the work which own will be engaged in the future carry on an adaptability training through this curriculum project, Exercises itself to analyze the question, to solve the question ability, will participate in the motherland for the present “the Four Modernizations” the construction to build a good foundation.目錄1杠桿的工藝性分析11.1杠桿的用途11.2杠桿的技術(shù)要求11.3確定杠桿的生產(chǎn)類型12、確定毛坯，繪制毛坯簡(jiǎn)圖12.1選擇毛坯12.2確定鑄造杠桿毛坯尺寸公差及機(jī)械加工余量22.2.1公差等級(jí)22.2.2 鑄件重量22.2.3鑄件的材質(zhì)系數(shù)23擬定工藝路線33.1選擇定位基準(zhǔn)33.1.1粗基準(zhǔn)的選擇33.1.2精基準(zhǔn)的選擇33.1.3表面加工方法的確定33.2撥叉零件各表面加工方案及加工余量43.3確定工藝路線43.4確定切削用量，時(shí)間定額53.4.1切削用量的計(jì)算53.4.2時(shí)間定額的計(jì)算64夾具設(shè)計(jì)74.1定位基準(zhǔn)選擇74.2定位元件的選擇74.3夾具設(shè)計(jì)及操作的簡(jiǎn)要說明74.4 定位誤差分析74.5夾具設(shè)計(jì)及操作的簡(jiǎn)要說明85設(shè)計(jì)新得8參考文獻(xiàn)9
