The invention relates to the processing technology of end tooth flange forks, in particular to a processing technology of an end tooth fork, which includes the following steps: the outer end of the vehicle, the milling and sinking holes, the drawing of the flower key, the countersinking plane, the drill ear hole, the boring ear hole and the reed groove, the drill installation hole and the chamfering deburring, and the drilling tool is effectively reduced by the milling and sinking machining. The frequency of damage is caused by the contact with the spline. In the milling hole, a fixturing fixture is used to fix the workpiece. The fixture includes the bottom plate, the vertical plate, the U shaped cover plate, the V block and the oil cylinder. The V block and the U cover plate fasten the blank end tooth forks on the milling machine to facilitate the machining of the milling and sinking holes. The bottom of the V block is made from the bottom of the V block. The oil cylinder can move up and down, and can adapt to the end gear fork clamping of different center. The fixture has the advantages of simple structure, convenient operation and strong generality. The invention effectively reduces the frequency of replacement of drilling tools and the maintenance frequency of the equipment through the improvement of the installation hole processing, and improves the production efficiency.

一种端齿突缘叉的加工工艺
本专利技术涉及端齿突缘叉加工工艺,具体涉及一种端齿突缘叉的加工工艺。
技术介绍
如今由于不同的厂商生产的变速箱、驱动桥输入、输出法兰存在差异,导致汽车的传动轴端齿突缘叉类型存在多样性,通用性较弱,为统一法兰类型,使法兰标准化,端面齿法兰应运而生。现端面齿法兰已成为国际标准,标准号为ISO12667。此标准规定了法兰齿形,统一了法兰类型,增强了通用性,并迎来了广阔的市场。故此,与变速箱、驱动桥输入、输出法兰配合的端齿型传动轴受到广大汽车厂商的青睐。而端面端齿突缘叉是端齿型传动轴的重要组成零件。由于端齿突缘叉法兰面为齿形,导致钻削端齿端齿突缘叉四安装孔时,会产生断续切削,钻头受力不均,会导致钻模套磨损快,加大了加工成本。故此,一种良好的端齿钻四孔加工工艺成为必需。目前一般的端齿突缘叉加工流程为:1、车外圆、端面;2、拉花键;3、锪四平面;4、钻两耳孔;5、镗两耳孔,切卡簧槽;6、钻四安装孔;7、倒角去毛刺。在此工艺流程中,钻四安装孔工艺存在钻模套寿命短、钻头磨损快的严重问题,钻模套更换频率快,使用很短时间就需要磨钻头切削刃,这些缺陷造成端齿突 ...
