Description

The brake disc usually needs to be ground during production and processing or after use.

[0003] However, in terms of grinding precision control, traditional grinding devices cannot dynamically adjust according to the actual state of the brake disc during the grinding process. Moreover, since heat is generated due to friction during the grinding of the brake disc, resulting in thermal deformation, and traditional devices cannot timely detect this deformation and adjust the grinding parameters, it is easy to generate processing errors, making the surface precision of the ground brake disc unable to reach the ideal state and affecting the stability of the braking performance.

A movable block 49 is slidably installed at the lower end of the moving block 48. A grinding block 53 is fixed to the lower end of the movable block 49. By means of the dual-axis motor 46, the two threaded rods 47 can be driven to rotate. Since the threaded rods 47 are screwed with the moving blocks 48, the moving blocks 48 can be driven to move, driving the grinding block 53 to adjust its position, and thus the brake disc 7 can be ground from the outside to the inside, realizing the efficient grinding of the brake disc 7. A fourth electric telescopic rod 54 is installed on the inner top wall of the moving block 48. The telescopic end of the fourth electric telescopic rod 54 faces downward and is fixedly connected with a pressure sensor 55.

At the same time, the temperature of the brake disc 7 can be monitored through the infrared temperature sensor 52. Since the brake disc 7 will heat up and expand during the grinding process, the expansion amount caused by friction heating on the surface of the brake disc 7 can be predicted, which is used as a reference for the feed amount of the grinding block 53. A dust suction hood 51 is installed on the side wall of the movable block 49.

[0027] The rotating mechanism includes a second motor 23 installed on the inner bottom wall of the device groove 36. The output shaft of the second motor 23 is fixedly connected to a first gear 22. A first toothed ring 21 is fixedly sleeved on the side wall of the rotating shaft 20. The first toothed ring 21 meshes with the first gear 22. By driving the first gear 22 to rotate through the second motor 23, since the first gear 22 meshes with the first toothed ring 21, the rotating shaft 20 can be driven to rotate, and thus the brake disc 7 can be driven to rotate. When the grinding block 53 contacts the surface of the brake disc 7, the surface of the brake disc 7 can be polished.

[0028] The supporting mechanism includes a support plate 3 fixedly connected to the upper end of the bottom plate 1. A support groove 4 is provided on the side wall of the support plate 3.

A one-way valve is provided inside the connecting channel 26, so that the lubricating grease can only enter the inside of the connecting channel 26 unidirectionally from the sliding plug cavity 27. A one-way valve is provided in the second connecting pipe 39, so that the lubricating grease can only enter the inside of the sliding plug cavity 27 unidirectionally from the storage tank 25. When the brake disc 7 finishes grinding, the rotating brake disc 7 still has residual kinetic energy. At this time, start the second electric telescopic rod 31 to extend, drive the magnetic attraction rotating block 35 to move upward to fit with the rotating shaft 20, and use the magnetic attraction between the magnetic attraction rotating block 35 and the rotating shaft 20 for transmission. The rotating shaft 20 can drive the magnetic attraction rotating block 35 to rotate. Furthermore, by the transmission of the second gear 30 and the second gear ring 32, the second gear 30 can be driven to rotate. The sliding plug plate 28 is driven to reciprocate inside the sliding plug cavity 27 through the connecting rod 29. The pumping action of the movement of the sliding plug plate 28 can be utilized to suck the lubricating grease inside the storage tank 25 into the sliding plug cavity 27, and then pump it into the cloth distribution cavity 45 through the connecting channel 26, the first connecting pipe 24, and the telescopic pipe 42. Through the through holes in the cloth distribution cavity 45, the lubricating grease is evenly infiltrated onto the wiping pad 44. Furthermore, the function of using the residual kinetic energy after the rotating grinding of the brake disc 7 to drive the automatic addition of lubricating grease to the wiping pad 44 is realized, which can save energy.

[0030] A maintenance mechanism is provided on the side wall of the support plate 3. The maintenance mechanism includes a rotary joint seat 40 installed on the side wall of the support plate 3. A first connecting pipe 24 and a telescopic pipe 42 are connected to the rotary joint seat 40. A third electric telescopic rod 41 is installed on the side wall of the rotary joint seat 40. The telescopic end of the third electric telescopic rod 41 is fixedly connected to a wiping box 43. A wiping pad 44 is fixedly embedded at the lower end of the wiping box 43. A cloth cavity 45 is provided inside the wiping box 43. Through holes are evenly distributed on the inner bottom wall of the cloth cavity 45. One end of the telescopic pipe 42 away from the rotary joint seat 40 is communicated with the cloth cavity 45. One end of the first connecting pipe 24 away from the rotary joint seat 40 is communicated with the connecting channel 26. By starting the third electric telescopic rod 41 to extend, the wiping box 43 can be driven to move to the surface of the brake disc 7. Then, by contacting the surface of the brake disc 7 with the wiping pad 44, the lubricating grease can be applied to the surface of the brake disc 7 through the wiping pad 44, so as to maintain the polished brake disc 7 and realize the automatic maintenance function of the brake disc 7 after polishing.

[0031] A first electric telescopic rod 11 is installed on the top of the mounting frame 2. The telescopic end of the first electric telescopic rod 11 penetrates downward through the mounting frame 2 and is fixedly connected to the upper end of the lifting plate 8. Four guide rods 10 are fixed to the upper end of the lifting plate 8. The guide rods 10 penetrate the inner top wall of the mounting frame 2 and are slidably connected to the mounting frame 2. By the telescopic movement of the first electric telescopic rod 11, the lifting plate 8 can be driven to move vertically for lifting.

[0032] When the present invention is used, at the beginning of the working process, the brake disc 7 is first positioned by the positioning column 19 and then sleeved on the four fixing screws 17 on the placing disc 16, and then the fixing nut 18 is tightened to complete the fixation.

[0033] Subsequently, the first electric telescopic rod 11 is started to push the lifting plate 8 to move downward along the guide rod 10. By the downward movement of the lifting plate 8, the grinding block 53 is driven to move downward to contact the brake disc 7. Then, the second motor 23 is started to drive the first gear 22 to rotate. By meshing with the first toothed ring 21, the rotating shaft 20 is driven to rotate, and then the brake disc 7 rotates. By using the relative movement between the grinding block 53 and the brake disc 7, the grinding of the brake disc 7 is realized. At this time, the fourth electric telescopic rod 54 pushes the pressure sensor 55 to make the movable block 49 drive the grinding block 53 to contact the surface of the brake disc 7. At the same time, the laser distance measuring sensor 50 real-time feeds back the distance data, and the infrared temperature measuring sensor 52 monitors the temperature change.

[0034] At the same time, the double-shaft motor 46 is started to drive the two threaded rods 47 to rotate synchronously, driving the moving block 48 to move, driving the grinding block 53 to adjust the position, and then the brake disc 7 can be ground from the outside to the inside, realizing the efficient grinding of the brake disc 7. The dust is continuously sucked through the dust suction hood 51.

[0035] After the single-sided grinding is completed, start the first electric telescopic rod 11 to contract, drive the lifting plate 8 to move upward, so that the grinding block 53 leaves the surface of the brake disc 7. At this time, the brake disc 7 is still rotating. Start the third electric telescopic rod 41 to push the wiping box 43 so that the wiping pad 44 soaked with grease contacts the surface of the brake disc 7. Start the second electric telescopic rod 31 to push the magnetic absorption rotating block 35 upward to adsorb the rotating shaft 20. Utilize the residual kinetic energy of the brake disc 7 to drive the transmission of the second gear ring 32 and the second gear 30, and then drive the sliding plug plate 28 to reciprocate in the sliding plug cavity 27 through the connecting rod 29. Pump the lubricating grease in the storage tank 25 into the sliding plug cavity 27 through the second connecting pipe 39, and then pump it into the cloth cavity 45 through the connecting channel 26, the first connecting pipe 24, and the telescopic pipe 42. Through the through holes in the cloth cavity 45, the lubricating grease is evenly infiltrated onto the wiping pad 44. Thus, the function of using the remaining kinetic energy after the rotary grinding of the brake disc 7 to drive the automatic addition of lubricating grease to the wiping pad 44 is realized, which can save energy.

[0036] After the maintenance of the brake disc 7 is completed, continue to start the first electric telescopic rod 11 to contract, drive the lifting plate 8 to move upward. When the lifting plate 8 triggers the pressure switch 13, start the first motor 6 to drive the rotating column 38 to flip 180 degrees to change the surface of the brake disc 7.

[0037] Then repeat the above grinding process, and continue to perform grinding and maintenance operations on the other side of the brake disc 7. After the two sides of the brake disc 7 are ground, the brake disc 7 can be removed.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
