The invention discloses an aluminum formwork integrated machining device. The aluminum formwork integrated machining device comprises a rack and lateral blocking rods. A portal frame is fixed to the rack in a welded mode, a hydraulic cylinder is mounted at the top of the portal frame, and a cutting machine body is mounted at the telescopic end of the hydraulic cylinder. A through groove is formedin the rack, the lateral blocking rods are movably arranged at the two ends in the through groove, the bottom ends of the lateral blocking rods are connected to a lead screw through threads, and a movable plate is movably arranged at the tops of the two lateral blocking rods. By driving the lead screw rotationally, the two lateral blocking rods can be driven simultaneously to move towards the middle synchronously; first springs push lateral pushing plates to clamp and fix the side faces of an aluminum formwork, the upper distances of the two lateral blocking rods is gradually shrunk, thus thetops of the lateral blocking rods press sliding plates, under the effect of guiding wheels, and a pressing plate is attached to the lateral blocking rods to downwards drive the movable plate to move downwards; and through guiding rods and second springs, the pressing plate can be pushed to be attached to the upper surface of the aluminum formwork in a compressed mode, thus the aluminum formwork isfixed to the position under the cutting machine body, and fixing is firm.
