[0031] Example:

[0032] See also Figure 1-2A vehicle brake disc repair device includes a base 1, a brake disc body 3 and a limit disc 4. A servo motor 2 is fixedly connected to the upper end of the base 1. A fixing component 5 is arranged on the upper side of the servo motor 2. The brake disc body 3 is arranged between the fixing component 5 and the limit disc 4. The fixing component 5 includes a rotating block 501 and a limit column 504. A threaded hole is opened on the limit disc 4, and a thread matching the threaded hole is engraved on the outer end of the limit column 504.

[0033] In the prior art, when repairing a brake disc, the surface of the brake disc is usually polished by a grinding wheel or sandpaper to grind off a thin layer of metal to remove wear or scratches. During the process, the brake disc needs to be fixed. Usually, a central axis is fixedly connected to the center position of the brake disc, and a central hole is opened on the central axis. The central axis and the central hole are used to fix the brake disc on the wheel axle, which usually matches the diameter of the wheel axle to ensure that the connection between the brake disc and the wheel axle is stable. In this solution, the user can fix the central axis position of the brake disc body 3 through the fixing component 5, and fix it through the limit plate 4 Strengthen the fixation, so that the brake pads on the periphery of the fixed brake disc body 3 can be exposed without being blocked, so that the clamping position does not need to be changed during the repair process, which effectively improves the repair speed. After the user fixes the brake disc body 3, the upper and lower surfaces of the brake disc body 3 can be polished by the polishing equipment at the same time. During the polishing process, the servo motor 2 is started to drive the fixing component 5 to rotate slowly and evenly as a whole, so that the polishing device can perform a circumferential polishing on the outer end of the brake disc body 3, which reduces manual operation and improves the accuracy of polishing.

[0034] See also Figure 3-4 The rotating block 501 is fixedly connected to the output end of the servo motor 2, the upper end of the screw 505 is fixedly connected to the mounting block 502, the inner cavity of the mounting block 502 is connected to the inner cavity of the limiting column 504, the inner wall of the limiting column 504 is threadedly connected with the screw 505, the bottom end of the screw 505 extends to the inner cavity of the mounting block 502, and the top of the screw 505 is fixedly connected with a hexagonal head 506, the outer end of the mounting block 502 is provided with a plurality of limiting holes connected to the inner cavity, and the fixing block 503 is slidably connected in the limiting hole, and a plurality of The fixing blocks 503 are arranged with inclined surfaces at one end close to each other, and the bottom end of the screw rod 505 is rotatably connected to the limiting block 507. The limiting block 507 is composed of a plurality of extrusion blocks arranged equidistantly in a ring shape, and the extrusion blocks match the fixing block 503. A plurality of positioning blocks 508 are fixedly connected to the bottom end of the inner wall of the mounting block 502. A limiting groove matching the positioning block 508 is provided at the bottom end of the fixing block 503, and a spring 509 is arranged in the limiting groove. Both ends of the spring 509 are fixedly connected to the inner wall of the limiting groove and the positioning block 508 respectively.

[0035] When fixing the brake disc body 3, the user first inserts the screw 505 and the limiting column 504 into the center hole of the brake disc body 3 in turn, so that the central axis of the brake disc body 3 is sleeved on the outer end of the mounting block 502, and the top of the inner wall of the central axis abuts against the top of the mounting block 502. Then, the user can use a wrench to turn the hexagonal head 506 to rotate the screw 505, so that the screw 505 moves downward along the inner wall of the limiting column 504, and the downward movement of the screw 505 drives the limiting block 507 to move on the mounting block 502. 02, the limiting block 507 squeezes the multiple fixing blocks 503, causing the multiple fixing blocks 503 to slide in the limiting holes and move synchronously to the outside of the mounting block 502 until the multiple fixing blocks 503 abut against the inner wall of the central axis of the brake disc body 3, so that the brake disc body 3 and the mounting block 502 are in the same axial position and the brake disc body 3 is fixed. Then the user sets the limiting plate 4 on the outer end of the limiting column 504 and threads the limiting plate 4 on the outer end of the limiting column 504. , and then rotate the limiting column 504 downward until the limiting column 504 abuts against the brake disc body 3, thereby further improving the fixing effect of the brake disc body 3 and preventing the brake disc body 3 from loosening during the grinding process. The diameters of the central axes of existing brake discs are mostly inconsistent. Through the provision of multiple adjustable fixing blocks 503, the device can be adapted to a variety of different types of brake discs. The fixing block 503 will stretch the spring 509 during the sliding process. When the user needs to release the fixing of the brake disc body 3 by the fixing block 503, it is only necessary to rotate the screw 505 in the opposite direction to reset the limiting block 507 upward, and then the multiple fixing blocks 503 will be reset and separated from the brake disc body 3 under the elastic force of the spring 509. In this solution, the outer ends of the multiple fixing blocks 503, the top of the mounting block 502 and the lower end of the limiting disc 4 are all equipped with rubber pads, which can effectively increase the friction when these surfaces abut against the brake disc body 3, thereby improving the fixing effect of the brake disc body 3 and avoiding wear on the outer surface of the central axis of the brake disc body 3.

[0036] Working principle:

[0037] When in use, the user first inserts the center hole of the brake disc body 3 into the screw rod 505 and the limiting column 504 in turn, so that the central axis of the brake disc body 3 is sleeved on the outer end of the mounting block 502, and the top of the inner wall of the central axis is abutted against the top of the mounting block 502. Then the user twists the hexagonal head 506 with a wrench to rotate the screw rod 505, so that the screw rod 505 moves downward along the inner wall of the limiting column 504. The downward movement of the screw rod 505 drives the limiting block 507 to move downward in the inner cavity of the mounting block 502. The limiting block 507 squeezes the multiple fixing blocks 503, so that the multiple fixing blocks 503 slide synchronously toward the outside of the mounting block 502 in the limiting holes until the multiple fixing blocks 503 are all aligned with the brake disc body. 3, so that the brake disc body 3 and the mounting block 502 are in the same axial position, and the brake disc body 3 is fixed. Then the user sets the limiting plate 4 on the outer end of the limiting column 504, and screws the limiting plate 4 to the outer end of the limiting column 504, and then rotates the limiting column 504 downward until the limiting column 504 abuts against the brake disc body 3, thereby further improving the fixing effect of the brake disc body 3. Then the user can use the grinding equipment to grind and repair the fixed brake disc body 3. During the grinding process, the servo motor 2 is started to drive the fixing assembly 5 to rotate slowly and evenly as a whole, so that the grinding device can perform a circumferential grinding on the outer end of the brake disc body 3.
