Tooth induction quenching one-time machining device for duplicate gear

The utility model discloses a tooth part induction quenching one-time processing device for a duplicate gear, which comprises side plates correspondingly arranged on two sides, a high-frequency induction coil is arranged on the side plate on one side in an extending manner, the high-frequency induction coil extends for a circle to form an upper-layer high-frequency induction coil, and a connecting part extends downwards to form a lower-layer high-frequency induction coil; and a lower-layer high-frequency induction coil is formed after the connecting part also extends for a circle, is correspondingly arranged below the upper-layer high-frequency induction coil, and correspondingly extends to be mounted on the other side plate. According to the device, the distance between the two high-frequency induction coils arranged up and down, the size, the outer diameter and the like of the induction coils correspond to two tooth parts of a duplicate gear, the duplicate gear is placed in the two high-frequency induction
