The locking buckle 12 can lock and unlock the input interface 210 and the connecting channel 110. The gun changing station 3 can accommodate multiple welding guns 200 of different models to meet the operation requirements. When the welding gun 200 needs to be replaced, the robot 300 moves the welding gun 200 to the gun changing position, so that the welding gun 200 extends into the limiting hole 310, and the positioning plate 22 is pressed on the bearing plate 31. The input interface 210 is unlocked in the connecting channel 110. The robot 300 moves the gun changing seat 11 to another gun changing position, and makes the gun changing seat 11 sleeved on the outer circumferential side of the input interface 210. The input interface 210 is locked in the connecting channel 110, so that the replacement of the welding gun 200 can be completed.
