the base is fixed on the turntable;
and the third rotating motor is used for driving the rotating disc to rotate.
10. A feeder hole polishing method implemented by the feeder hole polishing apparatus according to claim 1, comprising:
placing the antenna oscillator in an oscillator fixture;
the jig driving component drives the oscillator jig to rotate, and the position adjusting component pushes the antenna oscillator through the material pushing belt to enable the oscillator jig to slide, so that a feed line hole of the antenna oscillator is aligned to the polishing rod;
the polishing rod supply assembly drives the polishing rod to penetrate through the feeder hole of the antenna oscillator and is inserted into the rotary positioning groove of the magnet driving block;
the jig driving assembly drives the oscillator jig to rotate through the magnet driving block, so that the antenna oscillator rotates by taking the feeder hole as a rotation center.
