汽车转向节夹具方案新鲜出炉
汽车的羊角又叫“转向节”或“转向节臂”,就是车前工字梁两端承担转向功能的轴头。因为外观像羊的角,所以俗称“羊角”。//www.szfco.com/data/attachment/forum/201801/11/172728gs6xw5n589bw5hs5.jpg图1//www.szfco.com/data/attachment/forum/201801/11/172729el2e2e2zex79df6e.jpg图2 羊角三视图OP10:此款羊角有3角度,10、20、0都在一条轴线上,采用四轴,一次装夹做好整体。OP20:侧面加工两孔//www.szfco.com/data/attachment/forum/201801/11/172729rew2wxmju0kj4jng.jpg图3 羊角装夹效果JEEP大切诺基羊角(LR),回转轴回转直径为700mm。//www.szfco.com/data/attachment/forum/201801/11/172730mhmnwp0y6yonnyhh.jpg图4 反面加工设计//www.szfco.com/data/attachment/forum/201801/11/172730ttzg5vcs30pjyjoi.jpg图5 装夹零部件介绍//www.szfco.com/data/attachment/forum/201801/11/172730ruulyx8xluzl22yh.png图6 羊角加工细则//www.szfco.com/data/attachment/forum/201801/11/172730efx8slt4sfy3mn8h.png图7//www.szfco.com/data/attachment/forum/201801/11/172731w7q6yj5pk9yfibpn.jpg图8 锥孔加工编程锥孔加工顺序:1. Φ13钻头钻出小端直径。2. Φ12铣刀粗铣锥孔(粗铣为了减少精加工余量,保证尺寸稳定)。3. 锥度铰刀精加工。//www.szfco.com/data/attachment/forum/201801/11/172731t4j324bsjnjj3e23.jpg图9 侧面孔加工编程侧面孔加工顺序:1. T型刀反铣面,加工至Φ65。2. 孔口反倒角3x20。//www.szfco.com/data/attachment/forum/201801/11/172732d03shilmhd3edihd.jpg图10 T型刀//www.szfco.com/data/attachment/forum/201801/11/172732a3pvnxs1kqxeptse.png图11 装夹效果图//www.szfco.com/data/attachment/forum/201801/11/172733qw2d29q2wzqzhtun.png图12 安装细则安装细则:1. 内孔定位,芯做成菱形不但减少了接触面积而且减少过定位。2. 左右通用一副工装,取掉其中一个定位销即可。//www.szfco.com/data/attachment/forum/201801/11/172733xpbfzbzvsbhvxupu.jpg//www.szfco.com/data/attachment/forum/201801/11/172734x9d9752p8r86m8fd.jpg图13羊角//www.szfco.com/data/attachment/forum/201801/11/172734i834323w4u2omamm.jpg图14 羊角加工夹具目前因为减少工艺,工序集中后液压缸无法让位,故设计成手动装夹。牛掰{:3_59:} 看看 赞
