4. A control method of a screw drive based on automatic lubrication according to any one of claims 1-3, the control method comprising:
s1, when a driving mechanism drives a transmission worm (31) in a transmission box body (3) to rotate, in order to prevent the transmission worm (31) from being blocked during long-time movement, a pushing cylinder (37) in a mounting shell (36) works to push a sliding piston (38) to slowly advance in an oil inlet pipe (33), the working time of the pushing cylinder (37) is set through a control element, so that lubricating grease can be continuously provided for a buffer oil tank (32), and a buffer spring (39) can buffer the movement of the pushing cylinder (37);
s2, when the transmission worm (31) rotates, the meshing worm (4) is driven to rotate, and then the meshing worm (4) extracts lubricating grease in the buffer oil tank (32) and smears the outer surface of the transmission worm (31) in the meshing transmission process, so that lubrication of the transmission worm (31) is realized, the flow in the oil inlet pipe (33) can be detected through the flow meter (34), if the flow is lower than a limiting value, an alarm of the flow meter (34) alarms, the oil inlet pipe (33) is transparent, and the flow of the lubricating grease in the oil inlet pipe (33) can be observed visually at regular intervals from the scale wire groove (35), so that the long-term lack of the lubricating grease in the oil inlet pipe (33) is avoided:
s3, as the transmission worm (31) is meshed with the transmission worm wheel (5), lubricating grease is transferred to the surface of the transmission worm wheel (5), the rotating transmission worm wheel (5) is lubricated, meanwhile, the lubricating grease transferred by the transmission worm (31) can infiltrate into the annular cavity (51) through the adsorption of the capillary hole (55), and then seeps out from the capillary hole (55) at the other side and is supplied to the transmission worm wheel (5);
s4, along with the rotation of the transmission worm wheel (5), the internal meshing rack (52) rotates, so that the meshing gear (6) rotates at a constant speed in the annular cavity (51), lubricating grease in the meshing gear is stirred, the lubricating grease seeps out of the outer surface of the transmission worm wheel (5) through the capillary hole (55), when the lubricating grease is supplemented to the annular cavity (51), the transmission worm (31) is stirred by opening the movable port (21), the transmission worm wheel (5) rotates until infrared light of the infrared level meter (54) is emitted from the movable port (21), the oil filling port (53) is aligned with the movable port (21), and the lubricating grease can be supplemented to the annular cavity (51);
s5, in order to avoid the phenomenon that the angle is deviated and is blocked between the transmission worm wheel (5) and the lifting screw (1) when the transmission worm wheel (5) rotates, the counter-pole magnet (23) is driven to rotate through the transmission worm wheel (5) in the rotating process, so that the transmission worm wheel (5) keeps axially rotating around the axis of the lifting screw (1) under the action of the perpetual motion magnet (7), and the perpetual motion magnet (7) and the counter-pole magnet (23) provide auxiliary power for the rotation of the transmission worm wheel (5).
