The invention relates to an automatic punching clearing workstation for casting burr of an engine cast iron cylinder cover. The workstation comprises a conveying line used for conveying a casting, a punching machine used for punching the casting burr, a jig arranged on the punching machine and used for positioning a casting, a placement frame I used for allowing the jig to be placed, a transfer table used for bearing the jig and driving the jig to move, a clamp used for clamping the casting and driving the casting to move, a placement frame II used for allowing the transfer table and the clampto be placed, and a robot used for being connected with the transfer table or the clamp and controlling the transfer table or the clamp to move; and the conveying line, the punching machine, the placing frame I and the placing frame II are distributed around the robot by taking the robot as the center, and an industrial vision system is arranged between the conveying line and the punching machine. According to the automatic punching clearing workstation for the casting burr of the engine cast iron cylinder cover, manual participation is not needed, and the whole process automation is realized, so that the labor cost is reduced, and the machining efficiency is improved.
