传动轴凸缘叉加工工艺与夹具设计摘要传动轴是汽车传动系统中的重要部件，凸缘叉又是连接变速器和驱动桥的主要零件也是承受高速传动的零件。其结构和加工工艺直接影响零件的性能，进而影响整车动力传递的效果，其结构相对简单，但是加工工艺复杂。本文通过搜集资料了解传动轴凸缘叉结构特点，并对凸缘叉进行了参数分析以与加工的技术要求分析，并通过其在传动系统中的作用选取适当的材料并确定其工艺流程。 绘制工艺卡片，并查找资料分析相对应的加工机床以与所需要的刀具，明确每一步的加工余量，完成工序的编制过程。在确定工艺过程的前提下，根据传动轴凸缘叉的结构特点进行对应夹具的设计，根据零件图与加工端面设计其夹紧机构和定位元件、一起其他辅助零件与联合整体的零件，确定夹具机构方案，并明确如何拆装加工工件可以提高总体的效率问题。选取加工粗糙度，设计钻孔和铣端面的夹具装置以与钻孔夹具夹紧力的计算和夹具精度的的校核。 希望制造出精度更高的凸缘叉，使传动轴更好的运行，提高功率，减少资源浪费，改善工人的劳动条件，降低生产成本以与扩大机床的工艺围。关键词 凸缘叉；工艺流程；加工工艺；夹具设计Processing Technology and Design of the Jig of the Flange Yoke for ShaftAbstractDrive shaft is an important part in automobile transmission system, the flange yoke is connected to the transmission and drive axle of the main parts and it is under high speed driving . The structure and the processing technology impact on the performance of parts directly, in turn, influencing the effect of the vehicle power transmission, its structure is relatively simple, but complicated processing technology. Based on the collected data to understand the shaft flange fork structure characteristics, and the flange fork parameter analysis and processing technical requirements analysis, and through its role in the transmission system to select the appropriate materials and its technological process were determined. Card drawing process, and find the corresponding machine tool to analyze the data and tools needed t...
