气门摇臂轴支座零件的加工工艺规程设计(论文说明书10900字,工序卡,工艺卡,CAD图纸3张)
摘要
本文设计了气门摇臂轴支座零件的加工工艺规程，该规程可以很好满足生产实践的指导；。文章首先介绍了气门摇臂轴支座的作用和工艺分析，其次确定毛坯尺寸，然后进行了工艺规程设计，最后进行夹具设计。此次设计是对气门摇臂轴支座的加工工艺和夹具设计，其零件为铸件，具有体积小，零件结构简单的特点，由于面比孔易加工，在制定工艺规程时，就先加工面，再以面为基准来加工其它，其中各工序夹具都采用专用夹具，其机构设计简单，方便且能满足要求。

ABSTRACT
This paper introduces the design of valve lock shaft bearing parts processing procedure, this procedure can very well meet the production practice guidance 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: mechanical processing procedure, special jig, positioning error, clamping force
