The polishing station refers to the positions of the adjusting mechanism 200 and the polishing mechanism relative to the mounting body 100 when the adjusting mechanism 200 drives the polishing mechanism to move to a position for polishing the electrode cap of the welding gun. The initial station is the position of the adjusting mechanism 200 and the grinding mechanism relative to the mounting body 100 when the adjusting mechanism 200 drives the grinding mechanism to move to a position separated from the welding gun and does not affect the normal welding operation of the welding gun.
