In the new economic area,the industry presented a new development trend,and the trends also changes the quality and the performance of the production in some new abstracts. Machining industry is now taking place in structural changes, process design and improvement of equipment has become the necessary conditions of the enterprise survival and development, process equipment design and improved products directly affect the quality and performance. This article introduces the role and process analysis of the valve rocker arm bearing support,followed by determining blank size, and then proceed to order the design process, the final fixture design. What will be disgned is The machining process and fixture design of the Valve Rocker Arm Bearing support,which has the chatacteristics of three abstrcat.its components for castings, with a small size, simple structure and the characteristics of parts,because the surface is easier than the easy processing, point of order in the development process, the surface on the first processing , and then to surface as a benchmark to other processing, including the processes used special fixture, and its design is simple, convenient and can meet the requirements.KEYWORDS: Valve rocker arm bearing support, process analysis, Process design, fixture design Signature of Supervisor:目錄1緒論.11.1 本設(shè)計的內(nèi)容及意義.11.2 課題背景知識.21.2.1 零件的作用.21.2.2柴油機相關(guān)知識介紹21.2.3 機械制造工藝技術(shù)相關(guān)知識.31.2.4 機床夾具設(shè)計基礎(chǔ)知識.42 氣門搖臂軸支座的機械制造工藝規(guī)程設(shè)計72.1 零件的工藝分析及生產(chǎn)類型的確定72.1.1零件的作用72.1.2零件的工藝分析82.1.3確定零件的生產(chǎn)類型92.2 選擇毛坯，繪制毛坯圖102.2.1選擇毛坯種類102.2.2確定毛坯尺寸及機械加工總余量102.2.3設(shè)計毛坯圖122.2.4繪制毛坯圖.122.3 選擇加工方法，制定工藝路線122.3.1定位基準的選擇122.3.2零件表面加工方法的選擇132.3.3加工階段的劃分142.3.4工序的集中與分散142.3.5工序順序的安排152.3.6確定工藝路線162.3.7加工設(shè)備及工藝裝備的選擇.172.3.8工序間余量的確定.182.3.9切削余量及基本時間定額的確定203 氣門搖臂軸支座專用夾具的設(shè)計.303.1確定夾具的結(jié)構(gòu)方案303.1.1確定定位方案，選擇定位元件.303.1.2 確定導(dǎo)向裝置.323.1.3確定夾緊機構(gòu).323.1.4確定輔助定位裝置.333.2設(shè)計夾具體333.3 夾具裝配圖上標(biāo)注尺寸、配合及技術(shù)要求33總結(jié)36參考文獻37致謝38
