The invention relates to the technical field of electronic component assembly, especially to an automatic claw replacing apparatus. The automatic claw replacing apparatus has a claw warehouse for a plurality of insertion heads to dispose, and the installation ends of the insertion heads are exposed out of the claw warehouse. A separating member and a releasing member in cooperation for replacing the insertion heads are arranged on the claw warehouse, a clamp connection head is connected with the insertion heads, and has an insertion port for insertion connection of the installation ends of the insertion heads, and an elastic buckle is arranged on the inside wall of the insertion port of the clamp connection head. The elastic buckle is in clamp connection with clamping slots in the installation end of the insertion heads to realize connection between the clamp connection head and the insertion heads. The clamp connection head is provided with a buckle releasing portion which triggers the elastic buckle to release and cooperates with the separating member on the claw warehouse to trigger the elastic buckle to release, and the releasing member on the claw warehouse releases the insertion heads from the clamp connection head and places the insertion heads on the claw warehouse. The clamp connection head and the claw warehouse cooperate with each other to realize automatic dismounting and replacing an insertion head, the speed is fast, and the efficiency is high. Safety risk due to manually replacing claws can be reduced. The structure is simple, and the investment cost is low.
