The invention provides a vertical mill gearbox output shaft table fixing structure which comprises an output main shaft and an output shaft table plate, the output shaft table plate is fixedly installed on a gearbox, threaded grooves are formed in the top of the output main shaft and the middle of the output shaft table plate, and end covers are connected into the threaded grooves in a threaded fit mode. A second fixing groove is formed in the periphery of the interior of the end cover, the second fixing groove extends to the interior of the output shaft platen, and the end cover and the output shaft platen are connected with the second fixing groove in a matched mode through a plurality of first pins. By adopting the connecting mode of the end cover, the threaded groove and the extrusion plate, the shutdown accident caused by the fact that a bolt is broken due to rotation shearing when the output main shaft rotates is avoided, the deeper the end cover rotates, the firmer the threaded connection between the e
