The invention belongs to the technical field of welding manufacturing equipment, and mainly relates to an aluminum formwork robot welding work station which comprises a welding mechanical arm and a welding workbench. The welding mechanical arm is installed on one side of the welding workbench. The welding workbench comprises an aluminum formwork fixing table and two supports. The aluminum formworkfixing table is fixedly installed at the top ends of the supports. Fixed air cylinders are installed at the two ends of the top of the aluminum formwork fixing table. Air cylinder shafts of the fixedair cylinders are both provided with clamping plates. A positioning block is fixedly installed on the rear portion of the top end of the aluminum formwork fixing table. The top end of the support located at the rear end is provided with a connecting frame installation groove. A turning air cylinder is installed between the support located at the rear end and a first tool. A cross beam fixing mechanism is installed on a second tool frame. A cross beam adjusting mechanism is installed in the position, corresponding to a cross beam fixing mechanism, of the side wall of the second tool frame. Thealuminum formwork robot welding work station can automatically correct aluminum formwork cross beams, the speed of assembling and disassembling aluminum formworks is improved, and the welding qualityof the aluminum formworks is guaranteed.
