在生产ZQ型减速机时,由于其轴承盖之固定槽难于加工(图1),因此,我们设计了一种专用切槽刀(图2)。实践证明,这种刀具效果良好。这种工具可装在立铣上,也可改换刀杆装在钻床上。其工作原理为:刀杆1带动整个部件旋转。当纵向进给直至可换定位套7的肩胛与φ150孔壁吻合时,便达到预定切槽位置,刀杆1再继续向前,弹簧即压缩,于是刀座10就在刀杆1的斜孔中作相对运动,即沿销5作轴向滑移,从而产生刀体9的横(径)向切入。切槽的深度,可从弹簧的压缩量决 In the production of the ZQ gearbox, we designed a special grooving knife (Fig. 2) due to the difficulty of machining the fixing groove of the bearing cap (Fig. 1). Practice has proved that this tool works well. This tool can be mounted on the end mill, but also change the knife installed in the drilling machine. Its working principle is: Arbor 1 to rotate the entire part. When the vertical feed until the indexable sleeve 7 shoulder scapula and φ150 hole wall, it will reach the predetermined slot position, the arbor 1 and then continue forward, the spring that is compressed, so the knife 10 in the arbor 1 of the inclined hole In the relative movement, that is along the pin 5 for axial slip, resulting in the cutter body 9 horizontal (radial) cut. The depth of the groove can be determined by the amount of compression of the spring
