在普通插床上加工方孔时,一般通过(?)转工作台达到对各面的加工。这种方法比较麻烦,而遇到较长工件上插方孔就无法(?)转。为了解决这些问题,从而提高加工效率,我厂做了一个可利用刀盘定位孔(4个均布孔)定位,直接分度的活动插刀杆(图1)。经使用证明,不但可以插方孔,还可插8毫米以下轮毂键槽,效果良好。使用方法:把刀杆体6装在插床插头上,再将定位销3插入刀盘1的定位孔中,旋紧压紧螺母,插刀装在刀盘1的方孔中并紧固。当需要分度时,只要松开压 In the ordinary slot machine processing square hole, the general by (?) Turn table to reach the processing of all sides. This method is more troublesome, but in the face of longer work piece square hole can not (?) Turn. In order to solve these problems, so as to improve the processing efficiency, I made a cutter positioning hole (4 evenly distributed holes) positioning, direct indexing removable rod (Figure 1). The use of proof, not only can be inserted square hole, but also insert the following key wheel hub 8mm, the effect is good. Usage: Install the cutter bar body 6 on the plug of the slot machine, then insert the positioning pin 3 into the positioning hole of the cutter head 1, tighten the packing nut, insert the cutter into the square hole of the cutter head 1 and fasten it. When the need for indexing, just release the pressure
