The invention discloses a hydraulic shaft pressing machine for guide rail module machining. The hydraulic shaft pressing machine comprises a shaft pressing machine base. The lower end of the shaft pressing machine base is connected with supporting legs. The upper right end of the shaft pressing machine base is connected with an installing frame. A hydraulic shaft pressing machine body is fixed tothe installing frame. A guide rail module is arranged under the hydraulic shaft pressing machine body. An operation table is arranged at the lower end of the guide rail module. The hydraulic shaft pressing machine body comprises a hydraulic oil cavity. A telescopic cylinder is arranged in the hydraulic oil cavity. The lower end of the telescopic cylinder is connected with a piston. The lower end of the piston is connected with a rotor power cabin. A left motor and a right motor which are symmetric are arranged in the rotor power cabin. The upper ends of the motors are connected with a fixing plate. The lower end of each motor is connected with a perforating drill. The problems that a limiting device is not additionally arranged at the upper end of a traditional guide rail module, consequently, a shaft pressing machine cannot adjust fine errors, the hole rotating position is not accurate, and products are not qualified; and a single work head is adopted in an existing guide rail shaft pressing machine for work, the character of two symmetric sides of the guide rail module cannot be sufficiently combined, consequently, the work efficiency is low, and the yield is low.
