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
