[0049] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] With the rapid development of railway transportation, the transportation tasks of locomotives have also increased. In order to ensure the safety of locomotive transportation, regular maintenance is required to ensure the normal operation of locomotives. Among the maintenance tasks, rust removal of the brake discs is an important one. A clean and rust-free brake disc surface is an important condition for ensuring that the locomotive can brake normally.

[0051] Currently, rust removal of brake discs is typically done manually. The dust generated during this process can be harmful to workers, and the work is extremely inefficient. While laser equipment can be used to remove rust from brake disc surfaces, existing laser equipment has a low level of automation and struggles to remove rust from stepped holes in brake discs, resulting in poor rust removal effectiveness. Furthermore, manual adjustment is required when dealing with brake discs of different sizes, further reducing rust removal efficiency. Therefore, this embodiment provides a brake disc rust removal device to solve the above problems.

[0052] refer to Figures 1-6 The brake disc rust removal device provided in this embodiment is used to polish the brake disc 100. The brake disc rust removal device includes a frame 1, a first rust removal mechanism 2, a second rust removal mechanism 3, and a vision inspection mechanism 4. The first rust removal mechanism 2 removes rust from the surface of the brake disc 100, and the vision inspection mechanism 4 controls the second rust removal mechanism 3 to remove rust from the stepped holes of the brake disc 100, thereby reducing the difficulty of rust removal operations on the brake disc 100.

[0053] The brake disc 100 is provided with multiple stepped holes, which are evenly spaced around the axis of the brake disc 100. The first rust removal mechanism 2 includes a laser 21 and an adjustment component 22. The laser 21 is connected to the frame 1 through the adjustment component 22. The adjustment component 22 can adjust the position of the laser 21 so that the laser 21 can be aligned with the sides and periphery of the brake disc 100. The second rust removal mechanism 3 includes a connecting frame 31, a connecting plate 32, and multiple grinding heads 33. The connecting frame 31 is slidably connected to the frame 1. The connecting frame 31 can drive the connecting plate 32 and the grinding heads 33 to move along the axis of the connecting plate 32 so that the grinding heads 33 can be inserted into the stepped holes. The multiple grinding heads 33 are evenly spaced around the circumference of the connecting plate 32. The connecting plate 32 can move the grinding heads 33 radially along the connecting plate 32. The visual inspection mechanism 4 includes a camera 42, which is connected to the frame 1. The camera 42 can detect the relative position of the grinding heads 33 and the stepped holes.

[0054] During rust removal, the first rust removal mechanism 2 adjusts the position of the laser 21 via the adjusting component 22, enabling the laser 21 to be aligned with both sides and the periphery of the brake disc 100, thus removing rust from the periphery and two sides of the brake disc 100. The second rust removal mechanism 3 removes rust from the stepped holes of the brake disc 100 via the grinding head 33. When removing rust from the stepped holes, the position of the grinding head 33 is first adjusted according to the size of the brake disc 100 via the connecting plate 32. Then, the relative position of the grinding head 33 and the stepped hole is determined by the vision inspection mechanism 4 to align the grinding head 33 with the stepped hole. Finally, the grinding head 33 is moved by the connecting bracket 31 to insert into the stepped hole for rust removal. This brake disc rust removal device can remove rust from the surface and periphery of the brake disc 100 and can be adjusted according to different sizes of brake discs 100, thus enhancing both the rust removal effect and efficiency.

[0055] Specifically, refer to Figure 2The adjustment component 22 includes a first drive member 221 and a second drive member 222. The first drive member 221 is connected to the frame 1, and the second drive member 222 is connected to the movable end of the first drive member 221. The laser 21 is connected to the drive rod of the second drive member 222. The first drive member 221 enables the second drive member 222 and the laser 21 to move vertically, allowing the laser 21 to adjust its focus when cleaning the circumferential surface of the brake disc 100, ensuring the laser rust removal effect. The second drive member 222 enables the laser 21 to rotate around the axis of the drive rod. Through these two types of movement, the laser 21 can remove rust from the circumferential surface and both sides of brake discs 100 of different sizes, resulting in comprehensive and rapid rust removal and improving the efficiency of rust removal operations on the brake disc 100.

[0056] Furthermore, the adjustment assembly 22 also includes a connecting rod 223, which is L-shaped. One end of the connecting rod 223 is connected to the drive rod of the second drive member 222, and the other end of the connecting rod 223 is connected to the laser 21. This allows the laser 21 to avoid the brake disc 100 when it moves, thus preventing it from colliding with the brake disc 100. This allows the adjustment assembly 22 to perform comprehensive rust removal on the brake disc 100 using the laser 21 through two different movement methods.

[0057] Furthermore, the adjustment assembly 22 also includes a connecting plate 224, a first slider 225, and a first guide rail 226. The second drive component 222 is connected to the first drive component 221 through the connecting plate 224. The first guide rail 226 is connected to the frame 1. The first slider 225 is located on the side of the connecting plate 224 near the frame 1. The first slider 225 is slidably connected to the first guide rail 226, so that the laser 21 moves smoothly in the vertical direction, and at the same time, it can remain stable during rust removal to ensure the rust removal effect.

[0058] The specific type of the first driving component 221 is not limited here. In this embodiment, the first driving component 221 is a pneumatic push rod, but in other embodiments it can also be an electric push rod.

[0059] The specific type of the second driving component 222 is not limited here. In this embodiment, the second driving component 222 is a servo motor. The adjustment component 22 also includes a reducer. The second driving component 222 is connected to the connecting rod 223 through the reducer to ensure that the connecting rod 223 drives the laser 21 to rotate smoothly. In other embodiments, the second driving component 222 can also be a stepper motor.

[0060] Specifically, the connecting disc 32 includes a disc body 321, an adjusting disc 322, multiple adjusting rods 323, and a third driving component. The adjusting rods 323 are slidably connected to the disc body 321 and can only move along their own length. One end of the adjusting rod 323 extends out of the disc body 321 and is connected to the grinding head 33. The other end of the adjusting rod 323 is provided with a limit post 3231. The adjusting disc 322 is rotatably connected to the disc body 321 and is provided with multiple limit grooves 3221. The limit post 3231 is slidably connected to the limit grooves 3221. The third driving component can drive the adjusting disc 322 to rotate. When the adjusting disc 322 rotates, the limit grooves 3221 can drive the adjusting rods 323 and the grinding head 33 to move radially along the disc body 321. This allows for grinding of stepped holes in brake discs 100 of different sizes without the need for special device replacement, thus improving work efficiency.

[0061] There is no limitation on the type of the third driving component. In this embodiment, the third driving component is a servo motor, which is connected to the center of the adjustment disk 322 through a reducer. In other embodiments, it can also be a stepper motor.

[0062] Specifically, the distance from one end of the limiting groove 3221 to the center of the adjusting plate 322 is greater than the distance from the other end to the center of the adjusting plate 322. Since the adjusting rod 323 can only move along its own length, when the adjusting plate 322 rotates, the position of the limiting post 3231 in the limiting groove 3221 will change, thereby changing the distance from the limiting post 3231 to the center of the adjusting plate 322, which will drive the adjusting rod 323 and the grinding head 33 to move, thus realizing the change of the position of the grinding head 33, which is simple and quick.

[0063] Furthermore, the connecting plate 32 also includes a second guide rail 325 and a second slider 326. The second guide rail 325 is connected to the plate body 321, and the second slider 326 is connected to the adjusting rod 323. The second guide rail 325 and the second slider 326 are slidably connected. The second guide rail 325 and the second slider 326 can restrict the degree of freedom of the adjusting rod 323, so that the adjusting rod 323 can only move along its own length direction, and make the movement of the adjusting rod 323 smoother.

[0064] There is no limitation on the type of grinding head 33. In this embodiment, the grinding head 33 is a pneumatic grinding head, but in other embodiments it can also be an electric grinding head.

[0065] There is no limitation on the number of grinding heads 33. In this embodiment, there are six grinding heads 33, while the brake disc 100 has a total of 18 stepped holes. By simply rotating the brake disc 100 three times by 20°, all the stepped holes can be ground by the six grinding heads 33. In other embodiments, the number of grinding heads 33 can also be set according to the specific operation requirements.

[0066] Furthermore, the connecting disc 32 also includes a cover, which is connected to the disc body 321. The cover and the disc body 321 are connected to form a receiving cavity. The adjusting disc 322 is set in the receiving cavity. One end of the connecting rod 223 extends out of the receiving cavity, which can prevent dust from entering the receiving cavity during the grinding process, avoid affecting the rotation of the adjusting disc 322, and ensure the precise adjustment of the position of the grinding head 33.

[0067] Furthermore, the second rust removal mechanism 3 also includes a fourth driving member 34, a gear 35, a rack 36, at least two third guide rails 37, and at least two third sliders 38. The third guide rails 37 are connected to the frame 1, the third sliders 38 are connected to the connecting frame 31, and the third guide rails 37 and the third sliders 38 are slidably connected. The fourth driving member 34 is connected to the connecting frame 31, the gear 35 is connected to the driving end of the fourth driving member 34, the rack 36 is connected to the frame 1 and is arranged parallel to the guide rails, the gear 35 meshes with the rack 36, and the fourth driving member 34 can drive the gear 35 to rotate so as to drive the connecting frame 31 to move along the length direction of the rack 36.

[0068] The visual inspection mechanism 4 also includes a light source 41, which is connected to the frame 1. The light source 41 is mainly used to provide supplementary lighting for the camera 42, so that the camera 42 can more accurately detect the relative position of the grinding head 33 and the stepped hole. The specific form of the light source 41 is not limited here. In this embodiment, the light source 41 is in the form of a fence, and a through hole is provided in the middle of the light source 41. The camera 42 is set in the through hole to make the supplementary lighting of the light source 41 uniform and avoid the light from affecting the positioning of the camera 42.

[0069] refer to Figure 7 This embodiment also provides a brake disc cleaning station, including a brake disc clamping device and the above-mentioned brake disc rust removal device. The brake disc clamping device 200 can clamp the brake disc 100. The brake disc clamping device 200 is electrically connected to the vision inspection mechanism 4. The brake disc clamping device 200 can rotate the adjustment plate 322 of the vision inspection mechanism 4 to align the grinding head 33 with the stepped hole.

[0070] The brake disc clamping device 200 is electrically connected to the vision inspection mechanism 4, enabling the brake disc clamping device 200 to rotate the brake disc 100 according to the relative position of the grinding head 33 and the stepped hole, so that the stepped hole can be aligned with the grinding head 33 for grinding. When removing rust from the circumference and two sides of the brake disc 100, the brake disc clamping device 200 can rotate the brake disc 100 to cooperate with the laser 21 for rapid rust removal. This brake disc 100 cleaning line can automatically, comprehensively and efficiently remove rust from brake discs 100 of different sizes through the cooperation of the brake disc rust removal device and the brake disc clamping device 200, reducing the difficulty of rust removal, improving the efficiency of rust removal operations, and enhancing the rust removal effect.

[0071] Specifically, the brake disc clamping device is electrically connected to the vision inspection mechanism 4. The vision inspection mechanism 4 can transmit the relative position of the grinding head 33 and the stepped hole detected by the camera 42 to the brake disc clamping device, so that the brake disc clamping device rotates the brake disc 100 according to the relative position, so that the grinding head 33 and the axis of the stepped hole are collinear, ensuring that the grinding head 33 can be accurately inserted into the stepped hole.

[0072] refer to Figure 8 This embodiment also provides a method for removing rust from brake discs, which is performed using the aforementioned brake disc 100 cleaning line. This method includes:

[0073] S1. According to the size of the brake disc 100, the position of the laser 21 is adjusted by adjusting the component 22 so that the height of the laser 21 can be focused on the circumferential surface of the brake disc 100 to ensure the rust removal effect on the circumferential surface.

[0074] S2. By adjusting the component 22, the laser 21 is aligned with the two sides and the periphery of the brake disc 100 respectively. The laser 21 is started and the brake disc 100 is rotated by the brake disc clamping device. The second drive component 222 causes the laser 21 to rotate, so that the laser 21 is aligned with different surfaces of the brake disc 100. By rotating the brake disc 100, the relative position between the laser 21 and the surface of the brake disc 100 is changed, and the rust removal is completed on the surface of the brake disc 100.

[0075] S3. According to the size of the brake disc 100, the position of the grinding head 33 is adjusted by the connecting disc 32; the third driving component drives the adjusting disc 322 to rotate, so that the limiting groove 3221 drives the limiting post 3231 to change position, and then the connecting rod 223 drives the grinding head 33 to change position, so that the distance between the grinding head 33 and the center of the adjusting disc 322 is equal to the distance from the stepped hole to the center of the brake disc 100.

[0076] S4. Based on the relative position of the grinding head 33 and the stepped hole detected by the visual inspection mechanism 4, the brake disc 100 is rotated through the brake disc clamping device to align the stepped hole with the grinding head 33.

[0077] S5. The connecting frame 31 drives the grinding head 33 to move and insert it into the stepped hole, so that the grinding head 33 grinds the stepped hole. After grinding, the connecting frame 31 drives the grinding head 33 to exit the stepped hole. The fourth driving component 34 is activated, and the gear 35 drives the connecting frame 31 to move along the length direction of the rack 36, so that the grinding head 33 enters the stepped hole. After the grinding head 33 grinds the stepped hole, the fourth driving component 34 reverses and drives the grinding head 33 to exit the stepped hole.

[0078] S6. Rotate the brake disc 100 using the brake disc clamping device to align the grinding head 33 with the un-grinded stepped hole, and repeat S5 until all stepped holes are ground. In this embodiment, there are six grinding heads 33, and the brake disc 100 has a total of 18 stepped holes. By fixing and rotating the brake disc 100 three times at 20°, all stepped holes can be ground by the six grinding heads 33.

[0079] The brake disc rust removal device and brake disc clamping device can remove rust from the surface and stepped holes of the brake disc 100 respectively. They can also adapt to brake discs 100 of different sizes, which greatly reduces the difficulty of rust removal operations, improves the efficiency of rust removal operations, and enhances the rust removal effect.
