摘要
傳動軸是汽車傳動系統(tǒng)中的重要部件,凸緣叉又是連接變速器和驅(qū)動橋的主要零件也是承受高速傳動的零件。其結(jié)構(gòu)和加工工藝直接影響零件的性能,進(jìn)而影響整車動力傳遞的效果,其結(jié)構(gòu)相對簡單,但是加工工藝復(fù)雜。
本文通過搜集資料了解傳動軸凸緣叉結(jié)構(gòu)特點(diǎn),并對凸緣叉進(jìn)行了參數(shù)分析以及加工的技術(shù)要求分析,并通過其在傳動系統(tǒng)中的作用選取適當(dāng)?shù)牟牧喜⒋_定其工藝流程。 繪制工藝卡片,并查找資料分析相對應(yīng)的加工機(jī)床以及所需要的刀具,明確每一步的加工余量,完成工序的編制過程。在確定工藝過程的前提下,根據(jù)傳動軸凸緣叉的結(jié)構(gòu)特點(diǎn)進(jìn)行對應(yīng)夾具的設(shè)計,根據(jù)零件圖及加工端面設(shè)計其夾緊機(jī)構(gòu)和定位元件、一起其他輔助零件及聯(lián)合整體的零件,確定夾具機(jī)構(gòu)方案,并明確如何拆裝加工工件可以提高總體的效率問題。選取加工粗糙度,設(shè)計鉆孔和銑端面的夾具裝置以及鉆孔夾具夾緊力的計算和夾具精度的的校核。
希望制造出精度更高的凸緣叉,使傳動軸更好的運(yùn)行,提高功率,減少資源浪費(fèi),改善工人的勞動條件,降低生產(chǎn)成本以及擴(kuò)大機(jī)床的工藝范圍。

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.
