在加工蜗杆及大螺距螺纹时,常采用蜗杆弹簧刀轩来加工,起强力挑扣和抗震作用。但切削过程中,刀片径向前角几经修磨,厚度不断改薄,使刀片强度减弱和排屑不畅。为此,我们设计了前角可调的车刀。一、刀片前角调整该刀杆的车刀夹和刀夹杆的位置是由两件定位销来夹紧的,改变定位销1、2的位置可以改变前角的角度。在实践中,我们在加工模数6的蜗杆时,粗车选用14°径向前角,最大切刀深度在1.8mm左右。此时定位销位置见附图,定位销1插入刀杆的b孔位置,
In the process of worm and large pitch thread, often using worm spring knife Xuan to processing, play a strong buckle buckle and seismic effect. However, the cutting process, the blade radial rake several times by grinding, the thickness of thinning, the blade strength weakened and poor chip removal. To this end, we have designed a front-angle adjustable turning tool. First, the blade rake adjustment The tool holder and the tool holder clamp lever position is clamped by the two positioning pins, and change the location of pin 1, 2 can change the angle of the rake angle. In practice, we are processing the worm 6, the rough car used 14 ° radial rake angle, the maximum depth of about 1.8mm cutter. At this point positioning pin position see the photo, positioning pin 1 into the b-hole position of the arbor,
