图示为用于数控机床的端面铣刀切削刃自动更换装置的结构,其特点是铣刀可以在回转中更换切削刃。如图所示,在刀体上装有配着四个刀片的组合刀体(其中三个是备用齿),在铣刀外侧装一个驱动装置。当刀齿用钝,需要更换切削刃时,便对驱动装置发出指令信号,驱动装置在铣刀继续回转的情况下顶住锥销杠杆,使固定组合刀体的锥销脱开,同时,驱动杆使组合刀体回转,瞬间便可完成切削刃更换工作。
The figure shows the structure of an automatic tool changer for a face milling cutter used in a CNC machine tool. The feature is that the milling cutter can change the cutting edge during turning. As shown in the figure, a combination body with four blades (three of which are spare teeth) is mounted on the body and a drive is provided on the outside of the milling cutter. When the cutter with blunt, you need to replace the cutting edge, it will issue a command signal to the drive, the drive continues to rotate in the case of milling cone to withstand the lever pin, the fixed combination of body taper pin off at the same time, the drive Rod combination of body rotation, the moment can be completed cutting edge replacement.
