摘要
機械加工行業作為一個傳統而富有活力的行業，近十幾年取得了突飛猛進的發展，在新經濟時代，行業呈現了新的發展趨勢，由此對其它的質量，性能要求有了新的變化。現在機械加工行業發生著結構性變化，工藝工裝的設計與改良已成為企業生存和發展的必要條件，工藝工裝的設計與改良直接影響加工產品的質量與性能。
本文首先介紹了氣門搖臂軸支座的作用和工藝分析，其次確定毛坯尺寸，然後進行了工藝規程設計，最後進行夾具設計。此次設計是對氣門搖臂軸支座的加工工藝和夾具設計，其零件為鑄件，具有體積小，零件結構簡單的特點，由於面比孔易加工，在制定工藝規程時，就先加工面，再以面為基準來加工其它，其中各工序夾具都採用專用夾具，其機構設計簡單，方便且能滿足要求。
關鍵詞：氣門搖臂軸支座，工藝分析 ，工藝規程設計 ，夾具設計
Abstract
Machining industry ,as a traditional and vibrant industry, has been rapidly developed for a few past decades. 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
