It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1, as Figure 1-5 As shown, this utility model provides a grinding machine for processing brake discs, including a main board 1. A controller 2 is installed on the top of the main board 1. A lifting plate 3 is slidably connected to the top of the main board 1. A rotating plate 8 is rotatably connected inside the lifting plate 3. A pin 9 is fixed to one end of the rotating plate 8. Three second electric telescopic rods 10 are evenly distributed on the outer wall of the pin 9. A clamping plate 11 is fixed to the output end of each of the three second electric telescopic rods 10. A collection groove 14 is opened inside the main board 1. A connecting pipe 15 matching the collection groove 14 is fixed to the bottom of the main board 1.

[0026] The overall effect of Embodiment 1 is as follows: during use, the brake disc to be ground is placed onto the insert 9 through its central hole. The synchronous operation of the three second electric telescopic rods 10 drives the three clamping plates 11 to move, thereby internally clamping the brake disc. This clamping method greatly reduces the area occupied by the brake disc during clamping, allowing for more comprehensive subsequent grinding. After clamping, the operation of the hydraulic push rod 19 drives the first support plate 29 to descend, causing the two grinding discs 27 to move to both sides of the brake disc. The operation of the two third electric telescopic rods 22... The system moves the two grinding discs 27 closer to the brake disc for grinding. The operation of the drive structure 21 can move the two second support plates 20 up and down, thereby enabling the two grinding discs 27 to make more precise height adjustments, making the grinding effect on the brake disc more comprehensive and more practical. During grinding, the operation of the fan 17 can suck up the dust generated during grinding, which enters the connecting pipe 15 through the collection groove 14. Then, the dust is collected centrally through the external collection device connected to the mounting plate 31 at the bottom of the connecting pipe 15.
[0027] Example 2, as Figure 1-5As shown, the drive structure 21 includes a second fixing bracket 2101 fixed on both sides of the top of the first support plate 29. A second motor 2102 is installed on the inner side of the top of the first support plate 29. A screw 2103 is fixed to the output end of the second motor 2102. A movable plate 2105 is threadedly connected to the outer wall of the screw 2103. A limit post 2104 is slidably connected to the end of the movable plate 2105 away from the screw 2103. A first fixing plate 23 is fixed to the opposite end of each of the two third electric telescopic rods 22. A third motor 24 is installed to the opposite end of each of the two first fixing plates 23. A second fixing plate 25 is fixed to the opposite end of each of the two third motors 24. A docking plate 26 is bolted to the opposite end of each of the two second fixing plates 25. Two grinding discs 27 are respectively installed to the opposite ends of the two docking plates 26. A connecting plate 4 is fixed to the opposite ends of the two lifting plates 3 located below the main board 1. A connecting plate 4 is installed at the bottom end of the main board 1. There is a first electric telescopic rod 5, the output end of the first electric telescopic rod 5 is fixed to the connecting plate 4, the two lifting plates 3 are each fixed to the opposite end of the first fixing frame 6, the two first fixing frames 6 are each installed with a first motor 7, the output ends of the two first motors 7 are respectively fixed to the two rotating plates 8, the top end of the screw 2103 is rotatably connected to one of the second fixing frames 2101, the two ends of the limiting column 2104 are respectively fixed to the other second fixing frame 2101 and the first support plate 29, the first fixing plate 23 and the second fixing plate 25 are rotatably connected to the outside of the third motor 24 by a stabilizing plate 28, the side wall of the connecting pipe 15 is installed with a dustproof plate 16 on the side of the fan 17, the bottom outer wall of the connecting pipe 15 is installed with an installation plate 31, the bottom four corners of the main plate 1 are fixed with support legs 30, one end of the clamping plate 11 is fixed with a stop block 12, and the top of the main plate 1 is opened with a slanted opening 13 on the side of the collection tank 14.
[0028] The overall effect of Embodiment 2 is that, by setting up two grinding discs 27, both ends of the brake disc held by the inner support can be ground simultaneously. Compared with traditional single-sided grinding, this greatly reduces grinding time. Furthermore, the operation of the first motor 7 drives the rotating plate 8 to rotate, thereby causing the brake disc supported by the inner support on the outside of the insert post 9 to rotate. Then, the operation of the second motor 2102 drives the screw 2103 to rotate, causing the moving plate 2105 to rise and fall under the limit of the limiting post 2104. This allows for highly precise adjustment of the two grinding discs 27, making the grinding of the brake disc more comprehensive and improving its practicality. The operation of the first electric telescopic rod 5 can drive the lifting plate 3 to rise and fall as a whole, thereby increasing the distance between the insertion post 9 and the main board 1, making it easier to adjust brake discs of different widths and improving practicality. The operation of the two third motors 24 can drive the grinding disc 27 to rotate as a whole for grinding. The setting of the stabilizing plate 28 can provide auxiliary support for the first fixing plate 23 and the second fixing plate 25. The setting of the docking plate 26 can make the grinding disc 27 replaceable at any time. The setting of the inclined opening 13 can facilitate the grinding of the brake disc and guide it to fall into the external collection box.
[0029] Working Principle: When using this device, the brake disc to be ground is placed onto the insert 9 through its central hole. The synchronous operation of the three second electric telescopic rods 10 moves the three clamping plates 11, thus internally clamping the brake disc. This clamping method greatly reduces the area occupied by the brake disc during clamping, allowing for more thorough subsequent grinding. After clamping, the hydraulic push rod 19 drives the first support plate 29 to descend, moving the two grinding discs 27 to both sides of the brake disc. The operation of the two third electric telescopic rods 22 moves the two grinding discs 27 closer to the brake disc for grinding. The operation of the first motor 7 drives the rotating plate 8 to rotate, thereby rotating the brake disc internally supported by the insert 9. Then, through the operation of the second motor 2102, the screw 2103 is driven to rotate, causing the moving plate 2105 to rise and fall under the limit of the limiting column 2104. This enables the two grinding discs 27 to be adjusted with high precision, making the grinding of the brake disc more comprehensive and practical. During grinding, the operation of the fan 17 can suck up the dust generated during grinding, which enters the connecting pipe 15 through the collection groove 14. Then, through the external collection device connected to the mounting plate 31 at the bottom of the connecting pipe 15, the dust is collected in a concentrated manner. The controller 2 of this device can control the operation of the first electric telescopic rod 5, the second electric telescopic rod 10, the third electric telescopic rod 22, the first motor 7, the second motor 2102, the third motor 24, and the hydraulic push rod 19.
[0030] The wiring diagrams of the controller 2, the first electric telescopic rod 5, the second electric telescopic rod 10, the third electric telescopic rod 22, the first motor 7, the second motor 2102, the third motor 24, and the hydraulic push rod 19 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the controller 2, the first electric telescopic rod 5, the second electric telescopic rod 10, the third electric telescopic rod 22, the first motor 7, the second motor 2102, the third motor 24, and the hydraulic push rod 19 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
