According to the process of the oiling operation, the four-stage oiling machine is divided into four stages according to the sequence:

(1) the piston push rod 31 is in a contraction state, and the oil box body 41 is not attached to the surface of the guide rail in the pipeline. When the oiling operation is performed on the guide rail inside the pipeline, the oiling device is arranged inside the pipeline, the piston push rod 31 of the oiling device is in a contraction state at the moment, the piston push rod 31 is located at the lowest position of the stroke, the piston cylinder body 43 connected with the piston part 311 of the piston push rod 31 is also located at the lowest position, and the oil box body 41 connected with the piston cylinder body 43 is also located at the lowest position of the stroke. Because the compression spring 45 is positioned between the piston push rod 31 and the oil box body 41, the oil box body 41 moves upwards relative to the piston push rod 31 under the action of the compression spring 45 until the limiting body 44 mounted on the piston cylinder body 43 connected with the oil box body 41 contacts with the end surface of the limiting groove of the piston part 311 of the piston push rod 31 to realize limiting, the oil box body 41 cannot move upwards under the constraint of the limiting body 44, and the distance between the oil coating surface of the oil coating pad 42 on the oil box body 41 and the surface of the guide rail is 20 mm.

(2) The piston push rod 31 is in an extending state, and the oil box body 41 is attached to the surface of the guide rail in the pipeline. The piston push rod 31 in the pipeline moves upwards under the action of the lead screw nut pair 32, and the compression spring 45 props the oil box body 41 to move upwards. When the oil box body 41 moves 20mm, the oil box body 41 reaches the working position, the oil coating pad 42 on the oil box body 41 is in contact with the surface of the guide rail, and the oil coating device moves longitudinally along the guide rail to perform oil coating operation.

(3) The piston push rod 31 is in an extended state, and further oil supplement operation is carried out on the oiling pad 42. During the process of oiling the inner guide rail of the pipeline, when the grease stored in the oiling pad 42 is used up, the oiling operation needs to be carried out on the grease. The piston push rod 31 in the lifting mechanism 3 continues to move upwards under the driving of the motor 1, the lead screw 321 and the lead screw nut 322, the piston push rod 31 moves along the direction close to the oil box body 41, and the oil coating pad 42 adhered on the oil box body 41 is contacted with the surface of the guide rail and cannot move upwards. The piston rod 31 continues to move upward against the action force of the compression spring 45, and the stopper 44 moves downward away from the upper end surface of the stopper chute of the piston part 311 of the piston rod 31, with a movement distance of 10 mm. In the process, the volume of the grease filled in the inner cavity of the oil box body 41 is reduced, and the grease stored in the oil box body 41 is extruded out from the oil outlet hole on the surface of the oil box body 41 and enters the gap of the oil coating pad 42, so that the oil supplementing operation is realized. After the oil supplementing operation is finished, the guide rail oiling device moves longitudinally along the guide rail to continue oiling operation.

(4) The piston push rod 31 is in a contraction state, the oil box body 41 is separated from the surface of the track, and the oiling device withdraws from the pipeline to finish the oiling operation. The piston push rod 31 in the lifting mechanism 3 is driven by the motor 1, the lead screw 321 and the lead screw nut 322 to move downwards in a reverse direction, the oil box body 41 of the oiling component 4 also moves downwards in a reverse direction under the action of the piston cylinder 43, the limiting body 44 moves upwards to the upper end face of the limiting groove along the limiting groove on the side face of the piston part 311 of the piston push rod 31 to achieve limiting, the moving distance is 10mm, the oil box body 41 is continuously contacted with the surface of the guide rail under the action force of the compression spring 45, then the piston push rod 31 in the lifting mechanism 3 continues to move downwards under the drive of the motor 1, the lead screw 321 and the lead screw nut 322, and the oil box body 41 of the oiling component 4 also continues to move downwards under the action of the piston cylinder 43. At this time, the piston rod 31 of the lifting mechanism 3 drives the piston cylinder 43 through the limiting body 44, and then drives the oil box body 41 to continue moving downwards at the same time, the oil coating pad 42 moves downwards at the same time and is separated from the surface of the guide rail, when the downward movement distance is 20mm, the oil coating device returns to the contraction state, and at this time, the oil coating operation is completed.

The oiling device of the invention utilizes the lifting mechanism 3 which automatically adjusts the lifting and the oiling component 4 connected with the lifting mechanism 3 to facilitate the entering and exiting of the oiling device in the narrow pipeline, an oil outlet is arranged on the oil box body 41, and an oiling pad 42 and a sliding groove are further arranged to improve the oiling effect on the surface of the guide rail. Still further, through the cooperation of piston push rod 31 and piston cylinder 43, realize automatic oil supplementing operation to can realize the automation of whole fat liquoring operation. Its simple structure can reduce oiler's work load effectively, improves the work efficiency and the effect of fat liquoring simultaneously.
