The invention relates to filling equipment, in particular to a filling device for machine oil production. The filling device for machine oil production is accurate in filling and controllable in filling speed. The filling device for machine oil production comprises an installation frame, a placing unit, supporting rods, a frame body, discharging pipes, a valve and the like. the placing unit is arranged at the bottom inside the installation frame, the supporting rods are arranged on the left wall and the right wall inside the installation frame, and the frame body is connected between the supporting rods; and the discharging pipes are bilaterally-symmetrically arranged at the bottom of the frame body and are located above the placing unit and provided with valves. According to the filling device for machine oil production, a button is matched with a horn, so that when machine oil in a machine oil bottle reaches a certain quantity, the machine oil is taken away in time, and filling accuracy is improved; and a baffle is matched with the discharging pipes.
