Abstract
The invention discloses a numerically-controlled machine tool gearbox intelligent oil return system with an auxiliary oil tank and a working method of the numerically-controlled machine tool gearbox intelligent oil return system. The system comprises a gearbox, a main oil tank, the auxiliary oil tank, a filter, an oil pump, an oil scavenger pump, a liquid level sensor, an information receiver, a relay and the like. The auxiliary oil tank is mounted below one side of the gearbox. An oil inlet of the auxiliary oil tank is directly connected with the gearbox. An oil outlet of the auxiliary oil tank is connected to the main oil tank through the oil scavenger pump. The liquid level sensor is mounted in the auxiliary oil tank and controls turn-on and turn-off of the oil scavenger pump by detecting the height of the oil level. If the oil level in the auxiliary oil tank exceeds a set upper limit, the oil scavenger pump is turned on, and cooling oil in the auxiliary oil tank flows back into the main oil tank; when the oil level in the auxiliary oil tank is lower than a set lower limit, the oil scavenger pump stops working. By adopting the numerically-controlled machine tool gearbox intelligent oil return system, a whole oil channel is smooth in oil return, the oil scavenger pump is prevented from working continuously while the cooling effect is guaranteed, energy consumption is reduced, and the intelligent oil return function is achieved.
