我们在加工1000吨/日压榨机大齿轮键槽(m=28,内孔φ365,键槽宽80,键槽对称度公差0.08毫米),装夹时如图1所示。为了减少刨削中的让刀现象,我们采用了加强刀杆(图2),刀杆长度不宜过长,刀杆本体用厚壁钢管制作,以减轻自重。刀杆根部焊上两块加强筋板4。底板5直接固定在横刀架滑板上,刚度较好。采用双刃精插刀,它有两个刀刃,两刃的距离就是键槽的宽度,用于键槽精加工。加工时两刃对称并同时工作,其垂直于加工表面(键
We are processing the 1000t / day press gear wheel keyway (m = 28, bore φ365, keyway width 80, the keyway symmetry tolerance of 0.08 mm), when clamping as shown in Figure 1. In order to reduce shaving in the knife phenomenon, we use to strengthen the arbor (Figure 2), arbor length should not be too long, arbor body with thick-walled pipe to reduce weight. Arbor root welding two stiffener plate 4. Bottom plate 5 is fixed directly on the transverse carriage skateboard, the rigidity is better. Using double-edged precision knife, it has two blades, the distance between the two blades is the width of the keyway for keyway finishing. The two edges are symmetrical and work simultaneously at the time of machining, perpendicular to the machined surface (key
