The invention discloses a double-lifting device for bevel gears. The double-lifting device comprises a rack, a hydraulic cylinder and two identical lifting mechanisms, wherein each lifting mechanism comprises a lifting rod, a clamping seat, a driving rod, main clamping rods, a compression spring, a tail seat and movable clamping rods; each lifting rod is vertically arranged and fixedly mounted on the rack; each clamping seat movably sleeves the upper part of the corresponding lifting rod; the left end of each driving rod is movably hinged to the corresponding clamping seat, while the right end is movably hinged to a piston rod of the hydraulic cylinder; the rack is in sliding fit connection with a sliding groove in the middle of each driving rod; three main clamping rods are fixedly mounted on the side face of each clamping seat; each compression spring sleeves the corresponding lifting rod; each movable clamping rod is provided with an upper part and a lower part, and the included angle of the upper part and the lower part is an acute angle; three main clamping rods are arranged; and the lower ends of the main clamping rods are movably hinged to the upper parts of the movable clamping rods. Compared with the expensive manipulator and the traditional gear production mode, the double-lifting device for bevel gears has the advantages that labor is saved and the production cost of an enterprise is saved.
