A protrusion 21 is fixedly installed at one end of the third connecting rod 23 located outside the cooling cylinder 18. The protrusion 21 abuts against the outer surface of the cam 20.

One end of the first cooling tube 16 and the second cooling tube 17 which are connected to the cooling tube 18 are both located on the side of the cooling plug 33 away from the cam 20.

[0021] When the present invention is used, when the steering arm 2 rotates, the steering shaft 30 will rotate accordingly, thereby enabling the follower block 5 and the cam 20 to rotate synchronously. Before the follower block 5 rotates, the steering arm 20 is rotated by Figure 3 In this state, turning the knob 35 can rotate the threaded rod 34. Since the block 29 is close to the inner wall of the mounting groove 27 and the block 29 is threadedly mounted on the threaded rod 34, the block 29 and the adjusting rod 8 can be moved back and forth in the mounting groove 27. By setting the pointer 28 and the scale line 26, the vertical distance between the axis of the adjusting rod 8 and the axis of the steering shaft 30 can be changed. When the axis of the adjusting rod 8 does not coincide with the axis of the steering shaft 30 and the follower block 5 is in the vicinity, the adjusting rod 8 and the steering shaft 30 are in the vicinity. Figure 3 When the state rotates clockwise, the adjusting rod 8 will slide inside the moving frame 9, thereby causing the moving frame 9 to move toward the direction close to the first lubricating cylinder 6. By setting the first connecting rod 7 and the second connecting rod 11, the first lubricating plug 31 and the second lubricating plug 32 can be moved in the vicinity. Figure 5In this state, they all move to the left, so that the lubricating oil in the first lubricating cylinder 6 can be squeezed into the first lubricating pipe 10 and the third lubricating pipe 14 and finally sprayed to the rotating part of the steering arm 2 through the two oiling pipes 15, thereby reducing friction and wear. This is of great significance for extending the service life of the robot steering system and improving the durability of mechanical parts, reducing the heat and noise generated by friction, maintaining the smooth operation of mechanical parts, and avoiding performance degradation or failure due to excessive wear. It has a certain positive effect on preventing the control arm and other components from being damaged due to overheating. At the same time, the lubricating oil in the oil storage box 4 is sucked into the second lubricating cylinder 12 through the second lubricating pipe 13. When the axis of the adjusting rod 8 does not coincide with the axis of the steering shaft 30 and the follower block 5 is attached Figure 3 When the state rotates counterclockwise, the adjusting rod 8 will slide inside the moving frame 9, thereby causing the moving frame 9 to move toward the direction close to the second lubricating cylinder 12. By setting the first connecting rod 7 and the second connecting rod 11, the first lubricating plug 31 and the second lubricating plug 32 can be moved in the vicinity. Figure 5 In the state, they all move rightward, so that the lubricating oil in the second lubricating cylinder 12 can be squeezed into the third lubricating pipe 14 and sprayed to the rotating part of the steering arm 2 through the two oiling pipes 15, which also reduces the friction and wear of the rotating part, which is helpful for extending the service life of the robot steering system. At the same time, the lubricating oil in the oil storage box 4 is sucked into the first lubricating cylinder 6 through the fourth lubricating pipe 25. The greater the vertical distance between the axis of the adjusting rod 8 and the axis of the steering shaft 30, the greater the moving distance of the moving frame 9, that is, the steering arm 2 rotates a certain angle, and the amount of oil applied is more, so that the staff can make adjustments; When the axis of the adjusting rod 8 coincides with the axis of the steering shaft 30, as the follower block 5 rotates, its block 29 and the adjusting rod 8 will rotate accordingly, but its adjusting rod 8 cannot slide in the moving frame 9 in the up and down direction, that is, its moving frame 9 will not move, and at this time, it is impossible to oil the rotating part of the steering arm 2, which is convenient for the staff to realize the switch of the oiling function, and the practicality is stronger; When the cam 20 rotates, the spring 24 is provided so that the protrusion 21 always contacts the outer surface of the cam 20, thereby enabling the cooling plug 33 to slide in the cooling cylinder 18. Figure 6 When the cooling plug 33 rotates counterclockwise by a certain angle, it moves in the cooling cylinder 18 toward the cam 20, and the cold air in the air storage box 22 is sucked into the cooling cylinder 18 through the second cooling pipe 17. Figure 6 When the state is rotated clockwise by a certain angle, the cooling plug 33 moves in the cooling cylinder 18 in the direction away from the cam 20, and the cold air in the air storage box 22 will be squeezed into the first cooling pipe 16 and finally ejected through the blowing pipe 19, so that the rotating part can be cooled during the rotation of the steering arm 2.
