[0020] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-3 As shown, this embodiment discloses a brake ring rust removal device, including a housing 1, multiple support components 2, and a paper clamping component 3. The housing 1 includes a top plate 11 and a first ring plate 12. The top plate 11 includes a connecting shaft 15, which is fixed to the upper end face of the top plate 11. The connecting shaft 15 is connected to a handheld motor. The handheld motor locks the inserted connecting shaft 15. The housing 1 can be rotated by the drive of the handheld motor, so that the sandpaper can be rotated to remove rust from the inner wall of the brake ring.

[0022] The first ring plate 12 is located on the lower end face of the top plate 11. The support assembly 2 is installed on the first ring plate 12 and is distributed in a ring shape on the first ring plate 12. The support assembly 2 includes a push plate 21, which is located on the outer periphery of the first ring plate 12. The push plate 21 can move closer to or away from the first ring plate 12. The outer surface of the push plate 21 is an arc surface. The outer surfaces of multiple push plates 21 form a circle. The outer surfaces of multiple push plates 21 surround sandpaper 4. The sandpaper 4 can be fitted onto the circle formed by multiple push plates 21. The push plate 21 can be manually compressed to approach the first ring plate 12 so that the push plate 21 can be better inserted into the brake ring. After the force of compressing the push plate 21 is removed, the push plate 21 moves away from the first ring plate 12. The push plate 21 presses the sandpaper 4 against the inner wall of the brake ring. The inner wall of the brake ring is rubbed rust by the drive of a handheld motor.

[0023] The support assembly 2 includes a guide plate 22 and a first limiting plate 23. The guide plate 22 is fixedly connected to the push plate 21. The guide plate 22 is located on the side of the push plate 21 facing the first ring plate 12 and passes through the first ring plate 12. The first limiting plate 23 is located at the end of the guide plate 22 away from the push plate 21 and is located inside the first ring plate 12. The guide plate 22 extends radially along the top plate 11 and is slidably connected to the first ring plate 12, so that the push plate 21 can slide radially along the top plate 11. The first limiting plate 23 forms the limit at the outermost end of the push plate 21. When the first limiting plate 23 abuts against the first ring plate 12, the diameter of the circle formed by all the push plates 21 reaches its maximum.

[0024] The support assembly 2 includes a first guide rod 24 and a first spring 25. The housing 1 is provided with a second ring plate 13, which is located on the lower end face of the top plate 11 and inside the first ring plate 12. One end of the first guide rod 24 is connected to the first limiting plate 23, and the first guide rod 24 passes through the second ring plate 13. The first guide rod 24 and the second ring plate 13 form a radial guide. The first spring 25 is installed on the first guide rod 24 and abuts against the first limiting plate 23 and the second ring plate 13. The first spring 25 can abut against the first limiting plate 23 so that the push plate 21 can be kept at the position furthest from the first ring plate 12. The first spring 25 plays the role of resetting the push plate 21 after compression.

[0025] More preferably, the first guide rod 24 includes a threaded section and a nut. The threaded section is threadedly fixed to the guide plate 22, and the nut is located at the end of the first guide rod 24 away from the guide plate 22. The nut is located inside the second ring plate 13. The first guide rod 24 is fixed by the thread to fix the first limiting plate 23 on the guide plate 22, which is convenient for installation. There are two first guide rods 24, and the two first guide rods 24 are arranged at intervals along the length direction of the guide plate 22. The nut can limit the outward movement of the first guide rod 24.

[0026] The first ring plate 12 has a first opening 121. The paper clamping assembly 3 is installed on the housing 1. The paper clamping assembly 3 is located inside the first ring plate 12. The paper clamping assembly 3 includes a paper clamp 31. The opening of the paper clamp 31 faces the first opening 121. The paper clamp 31 can move closer to or away from the first opening 121. The two ends of the sandpaper 4 pass through the first opening 121 and are fixed to the paper clamp 31. The paper clamp 31 includes two clamping plates that can move closer to or away from each other. The two clamping plates can clamp the two ends of the sandpaper 4 located between them. The paper clamp 31 can move in the radial direction of the top plate 11 so that after the multiple push plates 21 are compressed, the sandpaper 4 can be pulled back by the paper clamp 31, so that the sandpaper 4 is kept taut on the multiple push plates 21, which better adapts to different sizes of brake rings for rust removal.

[0027] The housing 1 is provided with a support plate 14, which extends downward. The paper clamping assembly 3 is installed on the support plate 14. The paper clamping assembly 3 includes a second guide rod 32, a second spring 33, and a second limiting plate 34. One end of the second guide rod 32 is connected to the paper clamp 31, and the second guide rod 32 passes through the support plate 14. The other end of the second guide rod 32 is connected to the second limiting plate 34. The second spring 33 is installed on the second guide rod 32 and abuts against the support plate 14 and the second limiting plate 34. The second spring 33 can provide a thrust to the second limiting plate 34 away from the support plate 14, so that the paper clamp 31 can always keep the sandpaper 4 taut.

[0028] The second ring plate 13 is provided with a second opening 131, which corresponds to the first opening 121. The second opening 131 can avoid the paper clamping assembly 3. The edge of the first opening 121 is rounded to prevent the sandpaper 4 from being scratched by the sharp edge.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
