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 bee 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 ponents 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 更多論文 第 3 頁 共 51 頁 目錄 中文摘要 英文摘要 1 緒論 ..........................................................................................................................1 本設(shè)計的內(nèi)容及意義 ……………………………………………….….. 5 課題背景知識 ………………………………………………….…………1 零件的作用 …………………………………………………………… 錯誤 !未定義書簽。 柴油機相關(guān)知識介紹 2 機械制造工藝技術(shù)相關(guān)知識 ................................................................3 機床夾具設(shè)計基礎(chǔ)知識 ........................................................................4 2 氣門搖臂軸支座的機械制造工藝規(guī)程設(shè)計 9 零件的工藝分析及生產(chǎn)類型的確定 9 零件的作用 9 零件的工藝分析 9 確定零件的生產(chǎn)類型 11 選擇毛坯，繪制毛坯圖 11 選擇毛坯種類 11 確定毛坯尺寸及機械加工總余量 12 設(shè)計毛坯圖 13 繪制毛坯圖 ...........................................................................................14 選擇加工方法，制定工藝路線 14 定位基準(zhǔn)的選擇 1
