遼寧工程技術(shù)大學(xué)課程設(shè)計(jì)題目：偏心套的機(jī)械加工工藝規(guī)程及工藝裝備設(shè)計(jì)班級(jí)：機(jī)械05-2姓名：王赫指導(dǎo)教師：安亞君完成日期：2008.07.011摘要現(xiàn)今的世界國(guó)家間的競(jìng)爭(zhēng)已經(jīng)全面轉(zhuǎn)入科學(xué)技術(shù)的競(jìng)爭(zhēng)，而機(jī)械工業(yè)直接反應(yīng)一個(gè)國(guó)家的整體技術(shù)水平。無(wú)論是核工業(yè)還是農(nóng)具，機(jī)械制造業(yè)是國(guó)家獲取其他幾乎一切行業(yè)設(shè)施和工具的來(lái)源。可以說(shuō)人類文明史就是機(jī)械制造的歷史。我國(guó)的工業(yè)化建設(shè)情況，國(guó)際上眾說(shuō)紛紜，雖然在很多高技術(shù)項(xiàng)目上頗有建樹(shù)，但在這次汶川地震中表現(xiàn)出中眾多缺陷。包括規(guī)模較小，工藝粗糙，關(guān)鍵技術(shù)仍依賴國(guó)外等等。充分說(shuō)明在向高技術(shù)領(lǐng)域進(jìn)軍的同時(shí)，低端產(chǎn)業(yè)也應(yīng)該加強(qiáng)建設(shè)。本說(shuō)明書(shū)是為加工機(jī)械零件偏心套的加工過(guò)程而編寫。偏心套以其偏心結(jié)構(gòu)實(shí)現(xiàn)內(nèi)孔直徑可調(diào)，加上緊定螺絲，以達(dá)到內(nèi)圈周向、軸向固定的目的。但因?yàn)閮?nèi)圈內(nèi)孔是間隙配合，一般只用于輕載、無(wú)沖擊的場(chǎng)合。是一種較為常見(jiàn)的機(jī)械零件。關(guān)鍵詞：偏心套零件加工過(guò)程2ABSTRACTNowadays,thecompetitionofworldcountrieshasshifttothecompetitionofnewscienceandtechnologycompletely,Inthisage,levelofdevelopmentforthemachineindustryhasbecomethemostimportantcriteriainthejudgementinacountryslevelofdevelopment.FromNuclearindustrytodeadstock,ALLtheestablishmentandfacilities,hatourcountryneedandconsume,dependonourmachineindustry.ThehistroyofmankindisthehistroyofthemachinebuildingConsiderchineseindustryconstruction,Manyargumentationshasbeenbringforwardintheglobalityorganization.Weenjoyourachievementinsomenewtechnologes.ButintheseseriousearthquakeinWENCHUAN,wediscoveredourweakness:dimensions,asperoustechnics,coretechnologydependonothercountries.Sonotwithstandingtheseistheageofadvancedkrowlage,wemustimproveourwell-roundedtechnologies.Theseinstructionbookisformachinehardwareeccentricbushingsprocessingcycle.Theeccentricbushingwiththeirproprietarycompositionaccommodate3insidediameter,usethescrewtorealizetheaccommodateofinnerringslock-up.Bytbacausetheirclearancefitcomposition,theyapplytonon-orlight-load.Theyareatypeoffrequently-usedmachinehardware.Keyword:eccentricbushing,machinehardware,processingcycle4目錄1零件工藝性分析-51.1用途-51.2技術(shù)要求-51.3工藝性-61.4生產(chǎn)類型-62機(jī)械加工工藝規(guī)程設(shè)計(jì)-62.1確定毛坯，繪制毛坯簡(jiǎn)圖-62.2定位基準(zhǔn)-72.3加工方法-72.4加工階段與工序-82.5102，2R5側(cè)槽與側(cè)孔的加工余量，尺寸公差-83銑削加工夾具設(shè)計(jì)-103.1
