传动轴凸缘叉加工工艺及夹具设计 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Processing Technology and Design of the Jig of the Flange Yoke for Shaft Abstract Drive 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 to clear every step of the machining allowance, and complete the process of the compilation process. In determining the processes under the premise of according to the structural characteristics of the drive shaft flange fork corresponding fixture design, according to the detail drawing and processing end design of the fastening device and positioning device, other auxiliary parts together and united as a whole parts, jig institutions scheme is determined, and define how to tear open outfit machining can improve the efficiency of the overall problem. Selecting machining roughness, end of the design of drilling and milling fixture device and drilling clamp clamping force calculation and the precision of the check. That hopes to make the precision higher flange fork, make the shaft running better, improve power and reduce waste of resources, improve the working conditions of workers, reduce production costs and expanding process of machine tool.
