2-8, and further comprises the electrical connection of the electromagnetic control valves 2-8 and a sensor for monitoring the moving direction of the linear guide rail.
The working principle is as follows:
the deoiling slide block component 2 slides on the self-lubricating track 1 according to the actual required condition, in the sliding process, a sensor sends a signal to enable the electromagnet 2-2 to be electrified, the electrified electromagnet 2-2 can be matched with the magnetic ring 1-8-3, then the magnetic ring 1-8-3 is pushed to be far away from the electromagnet 2-2, when the deoiling slide block component 2 moves to a position, the electrified electromagnet 2-2 pushes the magnetic ring 1-8-3 to move towards the inside of the mounting groove 1-6, the magnetic ring 1-8-3 drives the discharge cylinder 1-8-1 to move, the oil discharge hole 1-8-2 on the discharge cylinder 1-8-1 is communicated with the oil discharge groove 1-5, and the oil discharge hole 1-8-2 cannot be vertically connected with the oil discharge groove 1-5 in the moving process of the discharge cylinder 1-8-1 Through the connecting rod 1-8-4, the simultaneously moving discharge cylinder 1-8-1 drives the push plate 1-8-5 to move, and simultaneously compresses the push spring 1-8-7, but the lubricating oil in the oil storage hole 1-3 cannot be discharged in time because the oil discharge hole 1-8-2 is not communicated with the oil discharge groove 1-5, so that the position of the lubricating oil push plate 1-8-10 in the oil storage hole 1-3 cannot be changed, but the push spring 1-8-8 is compressed due to the movement of the fixed sleeve 1-8-6, and then after the oil discharge hole 1-8-2 is communicated with the oil discharge groove 1-5, the compressed push spring 2-8-8 pushes the lubricating oil push plate 1-8-10 in the oil storage hole 1-8- And 3, sliding, pushing redundant lubricating oil into the discharge cylinder 1-8-1 from the oil storage hole 1-3, the oil discharge groove 1-5 and the oil discharge hole 1-8-2, then discharging the lubricating oil between the fixed rail body 1-1 and the sliding sleeve body 2-1 to form an oil film for lubrication, and when the lubricating oil is discharged, blocking the joint of the oil discharge groove 1-5 and the oil storage hole 1-3 by the lubricating oil pushing plate 1-8-10 so that the lubricating oil is not discharged outwards after a certain amount of lubricating oil is discharged each time.
Then when the oil removing slide block component 2 leaves the current position, because the electromagnet 2-2 does not limit the magnetic ring 1-8-3, the compressed pushing spring 1-8-7 pushes the plate 1-8-5 to push the discharge cylinder 1-8-1 to return to the original position, so that the oil discharge hole 1-8-2 is separated from the oil discharge groove 1-5, at the same time, the discharge cylinder 1-8-1 blocks the oil discharge groove 1-5, at the same time, the movable pushing plate 1-8-5 drives the fixed sleeve 1-8-6 to move, the fixed sleeve 1-8-6 drives the lubricating oil pushing plate two 1-8-10 to move back to the original position, then because the lubricating oil in the oil storage cavity 1-4 is reduced, the oil storage cavity 1-4 can form a cavity with a certain volume, then under the action of air pressure and a pushing spring 1-7-4, a sliding tooth column 1-7-3 moves upwards, the moving sliding tooth column 1-7-3 drives a lubricating oil pushing plate 1-7-5 to slide in an oil storage cavity 1-4, so that a cavity is removed, meanwhile, the matching of a limiting toothed plate 1-7-9 and the sliding tooth column 1-7-3 ensures that the lubricating oil pushing plate 1-7-5 cannot move downwards under the non-special condition, then when the oil storage cavity 1-4 is used for a certain time, the oil storage cavity 1-4 needs to be supplemented, the supplementing process is added into the oil storage cavity 1-4 through an oil feeding one-way valve 1-2, and the oil feeding one-way valve 1-2 sends a signal to a retractor to drag a pulling rod 1-7-6 to move outwards due to the work of the oil feeding one-way valve 1-2, then the pulling rod 1-7-6 drives the limiting toothed plate 1-7-9 to move outwards and separate from the sliding toothed column 1-7-3 through the pushing bolt 1-7-8, and then the lubricating oil pushing plate 1-7-5 moves downwards in the oil storage cavity 1-4 under the pressure of adding lubricating oil.
When the oil removal slide block assembly 2 leaves the fixed rail body 1-1, a sensor for monitoring the motion direction of the linear guide rail sends a signal to the electromagnetic control valve 2-8, so that the electromagnetic control valve 2-8 which is opposite to the motion direction is found to be open, then a suction pump connected to the discharge hole 2-7 acts on the collecting cylinder 2-5, and then the oil removal sleeve 2-3 of the slide sleeve body 2-1 which is far away from the motion direction sucks lubricating oil on the fixed rail body 1-1 through the oil through hole 2-4, so that the lubricating oil of the fixed rail body 1-1 is reduced, the adhesion of dust on the fixed rail body 1-1 can be effectively reduced, and the recovered lubricating oil can be filtered and reused.
