[0022] Please refer to Figures 1-4, the present utility model provides a technical solution for an automobile steering gear rack cleaning device, including: a device table 1 and a cleaning frame 2. A placing plate 18 is installed on the device table 1. A strip-shaped groove is provided on the placing plate 18. A resisting block 19 is arranged on the strip-shaped groove. Guide columns 28 are symmetrically installed at the bottom of the resisting block 19. Two springs 27 are installed inside the strip-shaped groove. The top ends of the two springs 27 are fixedly installed with the resisting block 19. The two guide columns 28 are located inside the two springs 27. Fixed plates 3 are symmetrically installed on the device table 1. A cross plate 15 is installed on the two fixed plates 3. A threaded rotating rod 16 is threadedly connected to the cross plate 15. The bottom of the threaded rotating rod 16 passes through the cross plate 15 and is rotatably connected to a resisting plate 17. The resisting plate 17 is located above the resisting block 19. Rotating the threaded rotating rod 16 drives the resisting plate 17 to move downward, adjusting the distance between the resisting plate 17 and the resisting block 19, so that the top end of the tooth drive abuts against the resisting plate 17 when the tooth is driven, and the resisting block 19 is completely pressed down into the placing plate 18.

[0023] As Figure 1 and Figure 2 shown, a cleaning frame 2 is installed on the device table 1, and a conveyor belt 10 is arranged on the device table 1. The conveyor belt 10 is located below the cleaning frame 2 and on one side of the placing plate 18. One end of the placing plate 18 is provided with a groove adapted to the conveyor belt 10. One end of the conveyor belt 10 is located at the groove of the placing plate 18. A cleaning roller 5 is rotatably connected between the two fixed plates 3. A driving motor 6 is installed on one fixed plate 3. A first connecting column 8 is rotatably connected to the other fixed plate 3. The power output end of the driving motor 6 is fixedly connected to one end of the cleaning roller 5. The driving motor 6 drives the cleaning roller 5 to rotate. The cleaning roller 5 drives the pulley 9 to rotate through the first connecting column 8. The pulley 9 drives the second connecting column 11 to rotate. One end of the first connecting column 8 is fixedly connected to the other end of the cleaning roller 5, and a pulley 9 is installed at the other end of the first connecting column 8. Support legs 4 are symmetrically installed at the middle position of the bottom of the device table 1.

[0024] As Figure 4 and Figure 5As shown in the figure, a transmission rod 23 is rotatably connected between two groups of support legs 4. A second connecting column 11 is rotatably connected to one group of support legs 4. The second connecting column 11 is fixedly connected to a pulley 9. A storage plate 7 is installed on the equipment table 1 on the other side of the placement plate 18. A water storage frame 12 is installed at the bottom of the equipment table 1 below the cleaning frame 2. A water pump 13 is installed on one side of the water storage frame 12. A connecting pipe 14 is installed on the water pump 13. The water storage frame 12 is used to store the cleaning liquid. The water pump 13 conveys the cleaning liquid through the connecting pipe 14 to the spray heads in the cleaning frame 2 for spraying. Spray heads are arranged inside the cleaning frame 2. The rack is conveyed on the conveyor belt 10, passes through the cleaning frame 2 where the cleaning liquid is sprayed, and then is conveyed to the placement plate 18. One end of the connecting pipe 14 is communicated with the spray heads. Sleeves 24 are symmetrically installed on the transmission rod 23. First push rods 25 are annularly arranged on the sleeves 24. Arc-shaped grooves adapted to the first push rods 25 are symmetrically arranged at the bottom of the placement plate 18. And strip-shaped grooves adapted to the first push rods 25 are symmetrically arranged on the placement plate 18. The strip-shaped grooves are communicated with the arc-shaped grooves. When the second connecting column 11 rotates, it drives the transmission rod 23 to rotate, thereby driving the first push rods 25 to rotate. The first push rods 25 push the rack to move on the placement plate 18 through the strip-shaped grooves. The rotation direction of the first push rods 25 is opposite to that of the cleaning rollers 5. When the rack moves, it abuts against the abutting blocks 19, squeezing the abutting blocks 19. The abutting blocks 19 move downward on the placement plate 18 to squeeze the springs 27. A telescopic cylinder 20 is installed at the bottom of the storage plate 7. The telescopic end of the telescopic cylinder 20 is installed with an adapter plate 21. A concave rod 22 is installed on the adapter plate 21. Second push rods 26 are symmetrically installed on the concave rod 22. Sliding grooves adapted to the concave rod 22 are arranged on the placement plate 18 on both sides of the strip-shaped grooves.

[0025] The working principle of the present utility model is as follows: Place the toothed steering gear rack to be cleaned with the teeth facing upward on the conveyor belt 10. The conveyor belt 10 drives the rack to move into the interior of the cleaning frame 2. The water pump 13 transports the cleaning liquid in the water storage frame 12 to the nozzles inside the cleaning frame 2 through the connecting pipe 14 for spraying. The cleaning liquid is sprayed on the rack. The conveyor belt 10 transports the rack to the placing plate 18. The driving motor 6 drives the cleaning roller 5 to rotate counterclockwise. The first connecting column 8 drives the second connecting column 11 to rotate clockwise through the pulley 9. The second connecting column 11 drives the transmission rod 23 to rotate together. The first push rod 25 on the transmission rod 23 contacts the rack on the placing plate 18 to push the rack. The rack abuts against the abutting block 19. The abutting block 19 moves downward on the placing plate 18. Rotate the threaded rotating rod 16. The threaded rotating rod 16 moves on the cross plate 15 to drive the abutting plate 17 to move downward, adjusting the distance between the abutting plate 17 and the abutting block 19. The abutting plate 17 blocks the rack, so that when the rack moves, it squeezes the abutting block 19. The abutting block 19 moves downward to squeeze the spring 27. After the rack moves past the abutting block 19, the abutting block 19 moves upward to reset by the elastic force of the spring 27. The rack passes through the abutting block 19 and also passes through the second push rod 26, blocking it on one side of the rack. The cleaning roller 5 rotates counterclockwise to brush the rack. After the rack is brushed, the telescopic cylinder 20 operates to drive the concave rod 22 to move, and through the second push rod 26, the brushed rack is pushed onto the storage plate 7.

[0026] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
