Description

Technical Field

[0001] This invention relates to the field of tea-picking robot technology, and in particular to a magnesium alloy steering control arm for a tea-picking robot. Background Technology

[0002] The magnesium alloy steering control arm is a key component of the tea-picking robot responsible for achieving the steering function. It is made of magnesium alloy material, which has the advantages of being lightweight, having a high elastic modulus, good heat dissipation, and good shock absorption. During the steering process, the steering control arm needs to bear and transmit the torque from the drive system to ensure that the robot can complete the steering action stably and accurately.

[0003] Currently, when the steering control arm of a tea-picking robot is in use, friction occurs in the rotating parts of the steering arm, which easily leads to high temperatures in the rotating parts and reduces the service life of each component. In addition, in order to ensure smooth steering of the steering arm, it is necessary for the staff to manually apply oil to the rotating parts of the steering arm regularly, which is quite troublesome. To address this, we have proposed a magnesium alloy steering control arm for tea-picking robots. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a magnesium alloy steering control arm for a tea-picking robot.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, the lubrication assembly includes an oil reservoir disposed on the outer wall of the follower block and fixedly mounted on the outer wall of one of its steering components. A first lubrication cylinder and a second lubrication cylinder are disposed on the oil reservoir. The first and second lubrication cylinders are located on opposite sides of the follower block. A movable frame is disposed between the first and second lubrication cylinders. An adjusting rod slidably connected to the inner wall of the movable frame is disposed within the movable frame. A first connecting rod slidably connected to the side wall of the first lubrication cylinder near the movable frame is disposed through the first lubrication cylinder. One end of the first connecting rod is fixedly connected to the side wall of the movable frame outside the first lubrication cylinder. A first lubrication plug slidably connected to the inner wall of the first lubrication cylinder is fixedly mounted on the end of the first connecting rod inside the first lubrication cylinder. A first lubrication pipe and a fourth lubrication pipe are disposed on the first lubrication cylinder and communicate with its interior. The ends of the first and fourth lubrication pipes connected to the first lubrication cylinder are both located on the side of the first lubrication plug away from the movable frame. The end of the fourth lubrication pipe away from the first lubrication cylinder is connected to the oil reservoir.

[0008] Preferably, a second connecting rod is slidably connected to the side wall of the second lubrication cylinder near the moving frame. One end of the second connecting rod outside the second lubrication cylinder is fixedly connected to the other side wall of the moving frame. A second lubrication plug is fixedly installed at the end of the second connecting rod inside the second lubrication cylinder, which is slidably connected to the inner wall of the second lubrication cylinder. The second lubrication cylinder is provided with a second lubrication pipe and a third lubrication pipe that communicate with its interior. The ends of the second lubrication pipe and the third lubrication pipe that communicate with the second lubrication cylinder are both located on the side of the second lubrication plug away from the moving frame. The end of the second lubrication pipe away from the second lubrication cylinder is connected to an oil storage box. The end of the first lubrication pipe away from the first lubrication cylinder is connected to the third lubrication pipe. The third lubrication pipe is provided with two oiling pipes that communicate with its interior.

[0009] Preferably, the adjustment assembly includes a threaded rod rotatably connected to the inner walls of both ends of the mounting groove, a block threaded onto the outer wall of the threaded rod, the block being fixedly connected to the adjustment rod, and one end of the threaded rod penetrating the inner wall of one end of the mounting groove and having a knob fixedly installed outside the mounting groove.

[0010] Preferably, the cooling assembly includes an air storage box disposed on the outside of the cam and fixedly connected to another steering component. A cooling cylinder is disposed on the air storage box. A third connecting rod is slidably connected to the end of the cooling cylinder near the cam. A protrusion is fixedly installed on the end of the third connecting rod outside the cooling cylinder. The protrusion abuts against the outer surface of the cam. A spring is fixedly connected between the protrusion and the cooling cylinder. A cooling plug is fixedly installed on the end of the third connecting rod inside the cooling cylinder and slidably connected to the inner wall of the cooling cylinder. A first cooling pipe and a second cooling pipe are disposed on the cooling cylinder and communicate with its inner wall. The ends of the first cooling pipe and the second cooling pipe that communicate with the cooling cylinder are both located on the side of the cooling plug away from the cam.

[0013] Preferably, the first lubrication pipe, the second lubrication pipe, the third lubrication pipe, the fourth lubrication pipe, the first cooling pipe, and the second cooling pipe are all equipped with one-way valves.

[0014] The beneficial effects of this invention are:

[0015] By setting up a lubrication component, lubricating oil can be automatically sprayed onto the rotating parts of the steering wall during the rotation of the steering arm, thereby reducing friction and wear. This is of great significance for extending the service life of the robot steering system, improving the durability of mechanical components, reducing heat and noise generated by friction, maintaining the smooth operation of mechanical components, avoiding performance degradation or failure due to excessive wear, and playing a positive role in preventing damage to components such as the control arm due to overheating.

[0016] By setting the adjustment component, the vertical distance between the adjustment rod axis and the steering shaft axis can be adjusted, thereby adjusting the amount of lubricating oil sprayed when the steering arm rotates at a certain angle. This makes it more convenient to use, easier to operate the oiling function to turn on and off, and more practical.

[0017] By installing a cooling component, air can be blown onto the rotating part of the steering arm when it rotates to a certain angle, thereby improving heat dissipation efficiency, helping the steering arm to dissipate the generated heat in a timely manner, keeping its operating temperature within a reasonable range, thus extending its service life and improving its operational stability.

[0018] When the steering arm rotates to a certain angle, this invention can not only automatically spray lubricating oil onto the rotating part of the steering arm, reducing friction and wear, and reducing heat and noise generated by friction, but also blow air onto the rotating part, thereby improving heat dissipation efficiency, helping the steering arm to dissipate the generated heat in time, and keeping its working temperature within a reasonable range. It is easy to use, and the amount of lubricating oil sprayed can be adjusted at will to meet the needs of use under different conditions. Attached Figure Description

A spring 24 is fixedly connected between the protrusion 21 and the cooling cylinder 18. A cooling plug 33 is fixedly installed at one end inside the cooling cylinder 18 and is slidably connected to the inner wall of the cooling cylinder 18. The cooling cylinder 18 is provided with a first cooling pipe 16 and a second cooling pipe 17 that are connected to its inner wall. The ends of the first cooling pipe 16 and the second cooling pipe 17 that are connected to the cooling cylinder 18 are both located on the side of the cooling plug 33 away from the cam 20. The second cooling pipe 17 is provided with two air blowing pipes 19 that are connected to its interior. The first lubrication pipe 10, the second lubrication pipe 13, the third lubrication pipe 14, the fourth lubrication pipe 25, the first cooling pipe 16, and the second cooling pipe 17 are all provided with one-way valves.

[0031] When this invention is used, when the steering arm 2 rotates, its 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, by means of the attached... Figure 3 In this state, rotating knob 35 allows the threaded rod 34 to rotate. Since block 29 is in close contact with the inner wall of mounting groove 27, and block 29 is threaded onto threaded rod 34, block 29 and adjusting rod 8 can move back and forth within mounting groove 27. By setting pointer 28 and scale 26, the vertical distance between the axis of adjusting rod 8 and the axis of steering shaft 30 can be changed. When the axis of adjusting rod 8 does not coincide with the axis of steering shaft 30 and follower block 5 is in the attached position... Figure 3 When the state rotates clockwise, the adjusting rod 8 slides inside the moving frame 9, causing the moving frame 9 to move closer to the first lubrication cylinder 6. By setting the first connecting rod 7 and the second connecting rod 11, the first lubrication plug 31 and the second lubrication plug 32 can be positioned in the adjacent... Figure 5In this state, the system moves to the left, which squeezes the lubricating oil in the first lubrication cylinder 6 into the first lubrication pipe 10 and the third lubrication pipe 14, and finally sprays it out onto the rotating part of the steering arm 2 through the two oiling pipes 15. This reduces friction and wear, which is of great significance for extending the service life of the robot steering system and improving the durability of mechanical components. It also reduces heat and noise generated by friction, maintains the smooth operation of mechanical components, and avoids performance degradation or failure due to excessive wear. It also plays a positive role in preventing damage to components such as the control arm due to overheating. At the same time, the lubricating oil in the oil reservoir 4 is drawn into the second lubrication cylinder 12 through the second lubrication 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 to the side... Figure 3 When the state rotates counterclockwise, the adjusting rod 8 slides inside the moving frame 9, causing the moving frame 9 to move closer to the second lubrication cylinder 12. By setting the first connecting rod 7 and the second connecting rod 11, the first lubrication plug 31 and the second lubrication plug 32 can be positioned in the adjacent... Figure 5 In this state, the system moves to the right, which squeezes the lubricating oil in the second lubrication cylinder 12 into the third lubrication pipe 14 and sprays it onto the rotating part of the steering arm 2 through the two oiling pipes 15. This also reduces the friction and wear of the rotating part, which helps to extend the service life of the robot steering system. At the same time, the lubricating oil in the oil storage box 4 is drawn into the first lubrication cylinder 6 through the fourth lubrication 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, when the steering arm 2 rotates a certain angle, more oil is applied, so that the operator can make adjustments.

[0032] 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. However, the adjusting rod 8 cannot slide in the vertical direction within the moving frame 9, that is, the moving frame 9 will not move. At this time, it is impossible to apply oil to the rotating part of the steering arm 2, which makes it easier for the staff to switch on and off the oiling function, making it more practical.

[0033] When the cam 20 rotates, the spring 24 ensures that the protrusion 21 always abuts against the outer surface of the cam 20, thereby allowing the cooling plug 33 to slide within the cooling cylinder 18. Figure 6 When the state is rotated counterclockwise by a certain angle, the cooling plug 33 moves towards the cam 20 inside the cooling cylinder 18, and the cold air in its air storage box 22 is drawn into the cooling cylinder 18 through the second cooling pipe 17. Meanwhile, when the cam 20 is in the adjacent... Figure 6When the state is rotated clockwise by a certain angle, the cooling plug 33 moves away from the cam 20 in the cooling cylinder 18, and the cold air in its air storage box 22 is squeezed into the first cooling pipe 16 and finally sprayed out through the air blowing pipe 19. In this way, the rotating part can be cooled during the rotation of the steering arm 2.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
