汽车后桥螺旋主动齿轮品种繁多，结构各不相同。图1所示结构，要求以齿的大端面定图1图2铣齿夹具1．夹具体2．弹簧夹头3．锥套位设计铣齿夹具。由于工件定位直径D2与齿轮齿根大端直径D1相同，所以设计夹具的夹具体上必须留铣出刀槽（图2）。出刀槽的长度取决于铣齿刀盘的直径。
Rear axle screw drive gear a wide range of different structures. The structure shown in FIG. 1 requires that the large end face of the tooth should be set as shown in FIG. 1 and FIG. 2. Clamp body 2. Collet 3. Taper set design milling gear fixture. Since the workpiece positioning diameter D2 and the gear root big diameter D1 the same, so the clamp fixture design body must leave a milling groove (Figure 2). The length of the discharge slot depends on the diameter of the milling cutter head.
