The working principle of the basic scheme is as follows: the oil discharging connector is connected to an oil duct of the robot, and the motor is started, so that the motor drives the central shaft to rotate in a fixed direction, and the central shaft drives the first sliding plate and the second sliding plate to move towards one side far away from the cleaning cavity when rotating. In the process, the pressure in the oil cavity and the air cavity is increased, the one-way oil discharge valve is automatically opened, lubricating oil in the oil cavity is discharged through the first pipeline, gas in the air cavity is discharged through the third pipeline, the gas and the lubricating oil are converged in the oil delivery pipeline and then discharged through the oil discharge joint, and the discharged gas and lubricating oil enter an oil duct of the robot. At the same time, the pressure in the cleaning cavity is gradually reduced. When the valve is opened, the lubricating oil in the robot oil duct is sucked into the cleaning cavity together with dust and fragments through the oil discharging joint and the second pipeline. Starting the motor again, wherein the rotation direction of the motor is the same as that of the last time, continuously extruding the oil cavity by the first sliding plate, and introducing clean lubricating oil into the robot oil duct. After a certain amount of lubricating oil is introduced, the motor is reversed, and the central shaft rotates to drive the first sliding plate and the second sliding plate to move towards one side of the cleaning cavity. In this process, the first and second sliding plates gradually return to the original positions due to the change of the rotation direction of the central shaft. In the process that the first slide plate and the second slide plate move to one side of the cleaning cavity, the pressure in the cleaning cavity is gradually increased, the piston overcomes the acting force of the spring and moves downwards along the concave cavity, when the piston moves to the lower part of the oil drain port, waste lubricating oil in the cleaning cavity and chips can be sequentially discharged through the oil inlet, the concave cavity and the oil drain port, and waste in the cleaning cavity is cleaned timely.
