[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a brake disc grinding and dressing device: 1. When grinding the edges of the brake disc, the rotation of the first drive motor drives the active disc to rotate. This rotation of the active disc drives the belt, causing the two driven discs at one end of the belt to rotate. This, in turn, drives the two shafts at the top to rotate. As the shafts rotate, they drive the sandpaper grinding cylinders, which are fixed to the outer side, to grind the edges of the brake disc, removing rust and burrs. The sandpaper cylinders need to be replaced after a certain amount of grinding. 2. When grinding the outer side of the car brake disc, the third drive motor rotates the fixed clamping disc and the rotating disc to rotate at a certain angle. Then, the fourth drive motor rotates the fixed shaft to adjust the angle of the mounting plate until the two grinding discs are in contact with the outer side of the brake disc. The fourth drive motor is then turned off, and the pressure applied to the grinding disc and brake disc is dynamically adjusted by a small electric telescopic rod to avoid over-grinding the brake disc. A laser rangefinder scans the surface of the brake disc with a laser beam, and the photoelectric receiving system captures the changes in the light signal in real time. The data processing system processes and analyzes the received signal to obtain the smoothness data of the brake disc.

[0013] 3. Harmful dust is generated during the grinding of the brake disc. The filter shell and dust collection bucket are pushed close to the side of the brake disc by the extension and retraction of the fifth electric telescopic rod. Then, the vacuum cleaner is turned on and the harmful dust generated during grinding is sucked in through the dust collection bucket. The dust is absorbed and filtered by several layers of filter screens inside the filter shell, so that the dust is filtered down and prevented from being inhaled by the operator.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "configuration" should be interpreted broadly. For example, they can refer to a fixed connection or configuration, a detachable connection or configuration, or an integral connection or configuration. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] like Figures 1-12 As shown, the present invention proposes a brake disc grinding and finishing device, including a fixed mounting frame 1. Two slide rails 101 are fixedly mounted on the top of the fixed mounting frame 1. A first sliding seat 102 is slidably connected to one end of the top of the slide rails 101. A grinding mechanism 2 is fixedly connected to one side of the top of the first sliding seat 102. A fixing mechanism 3 is fixedly connected to the other side of the top of the first sliding seat 102. A grinding limiting mechanism 4 is provided on the top of the fixing mechanism 3. A second sliding seat 103 is slidably connected to the top of the other end of the slide rails 101. A dust removal mechanism 5 is provided on the top of the second sliding seat 103. A control mechanism 6 is fixedly connected to one side of the top of the fixed mounting frame 1.

[0021] The grinding mechanism 2 includes a limiting groove 201 that opens and closes to the top of the first sliding seat 102. A first electric telescopic rod 202 is fixedly connected inside the limiting groove 201. One end of the first electric telescopic rod 202 is fixedly connected to a movable seat 203 that slides through the limiting groove 201. A first drive motor 204 is fixedly connected to the bottom end of the movable seat 203. A main turntable 205 is fixedly connected to the transmission end of the first drive motor 204. Two slave turntables 206 are movably connected to the top of the movable seat 203. A rotating shaft 207 is fixedly connected to the top of the slave turntables 206. A top plate 208 is inserted and limited at the top of the rotating shaft 207. A second electric telescopic rod 209 is fixedly connected to the bottom end of the top plate 208. Guide rods 2010 are fixedly connected to both sides of the top plate 208. The bottom end of the guide rod 2010 is inserted and connected to the movable seat 203. A belt drives the main turntable 205 and the two slave turntables 206.

[0022] In practical use, when grinding the sides of the brake disc, in order to replace the sandpaper cylinder during grinding, the extension and retraction of the first electric telescopic rod 202 pushes the movable seat 203 inside the limiting slide groove 201. During the limiting sliding process, the movable seat 203 can move and adjust the sandpaper cylinder close to the side of the brake disc for grinding. The rotation of the first drive motor 204 drives the main turntable 205 to rotate, which in turn drives the belt. The two slave turntables 206 at one end of the belt rotate, which in turn drives the two rotating shafts 207 at the top to rotate. During the rotation of the rotating shafts 207, the sandpaper cylinder fixed on the outside is driven to grind the sides of the brake disc to remove rust or burrs. When grinding reaches a certain point, the sandpaper cylinder needs to be replaced. The extension and retraction of the second electric telescopic rod 209 pushes the top plate 208 to remove the sandpaper cylinder on the rotating shaft 207, thus facilitating the replacement of the new sandpaper cylinder.

[0023] The fixing mechanism 3 includes a circular fixing seat 301 fixedly connected to the top of the first sliding seat 102. A rotating disk 302 is movably connected to the top of the circular fixing seat 301. Several fixing limit posts 303 are fixedly connected to the top of the rotating disk 302. A device frame is fixedly connected to the side of the first sliding seat 102. An arc-shaped shell 304 is fixedly connected to the top of the device frame. A temperature sensor 305 is fixedly installed on one side of the arc-shaped shell 304. A pressure sensor 306 is fixedly connected to the top of the rotating disk 302.

[0024] In practical use, when grinding automotive brake discs, the brake discs need to be limited in their installation. To facilitate grinding, the brake discs are mounted on a rotating disc 302, and several limiting posts 303 limit the brake discs as they are inserted into the holes in the brake discs. The rotating disc 302, in conjunction with the grinding limiting mechanism 4, is driven to rotate, allowing the brake discs to be ground 360°. During the grinding process, the temperature sensor 305 on the arc-shaped shell 304 monitors the temperature of the brake discs. To prevent the brake discs from deforming due to excessive grinding temperature, a pressure sensor 306 monitors the grinding pressure of the grinding structure during the grinding process, thereby better controlling the dynamic feed adjustment of the grinding structure to grind the outer side of the brake discs.

[0025] An electric hydraulic cylinder 1021 is fixedly connected to one side of the first sliding seat 102.

[0026] In practical use, the electric hydraulic cylinder 1021 drives the first sliding seat 102 to slide on the slide rail 101, thereby removing the brake disc after grinding at the bottom of the grinding limit mechanism 4 for unloading.

[0027] The grinding limiting mechanism 4 includes a fixed frame 401 fixedly connected to the top two sides of the fixed mounting frame 1. A fixed plate 402 is fixedly connected to the top of the fixed frame 401. A third electric telescopic rod 403 is fixedly connected to the top center of the fixed plate 402. A device frame 404 is fixedly connected to the telescopic end of the third electric telescopic rod 403. A third drive motor 405 is fixedly connected inside the device frame 404. A fixed clamping disc 406 is fixedly connected to the transmission end of the third drive motor 405. A limiting hole 408 is opened at the bottom of the fixed clamping disc 406, which is inserted and connected to a plurality of limiting posts 303. A laser rangefinder 409 is fixedly connected to one side of the bottom end of the fixed clamping plate 406; The top two ends of the fixed plate 402 are fixedly connected to the fourth drive motor 4010. The transmission end of each fourth drive motor 4010 is fixedly connected to the fixed shaft column 4011. The bottom end of the fixed shaft column 4011 is fixedly connected to the mounting plate. One end of the mounting plate is fixedly connected to two small electric telescopic rods 4012. The telescopic end of the small electric telescopic rod 4012 is fixedly connected to the device plate. The top of the device plate is fixedly connected to the frequency modulation motor 4013. The transmission end of the frequency modulation motor 4013 is fixedly connected to the grinding disc 407.

[0028] In practical use, during brake disc polishing, to achieve 360° rotation polishing, the third electric telescopic rod 403 extends and pushes the fixed clamping plate 406 under the device frame 404. Several limiting holes 408 on the fixed clamping plate 406 and limiting posts 303 interlock to limit and fix the car brake disc. When polishing the outer side of the car brake disc, the third drive motor 405 rotates, causing the fixed clamping plate 406 and the car brake disc on the rotating disc 302 to rotate 360°. Then, the fourth drive motor 4010 rotates, causing the fixed shaft post 4011 to rotate. The mounting plate is angled until the two grinding discs 407 are in contact with the outer side of the brake disc. The fourth drive motor 4010 is turned off. The small electric telescopic rod 4012 is used to dynamically adjust the pressing pressure between the grinding discs 407 and the brake disc to avoid over-grinding the brake disc. The frequency-modulated motor 4013 drives the grinding discs 407 to grind the brake disc. The brake laser rangefinder 409 scans the surface of the brake disc with a laser beam. The photoelectric receiving system captures the changes in light signal in real time. The data processing system processes and analyzes the received signal to obtain the smoothness data of the brake disc.

[0029] The dust removal mechanism 5 includes a fourth electric telescopic rod 501 fixedly connected to one side of the second sliding seat 103, a vacuum cleaner 502 fixedly connected to the top of the second sliding seat 103, a corrugated hose 503 fixedly connected to the air inlet end of the vacuum cleaner 502, a filter shell 504 fixedly connected to one end of the corrugated hose 503, a closing switch door 505 installed on one side of the filter shell 504, several filter screens 506 engaged inside the filter shell 504, a dust collection hopper 507 provided on one side of the filter shell 504, and a fifth electric telescopic rod fixedly connected to the bottom end of the filter shell 504.

[0030] In practical use, harmful dust is generated during the polishing of the brake disc. The filter housing 504 and the dust collection bucket 507 are pushed close to the side of the brake disc by the extension and retraction of the fifth electric telescopic rod. Then, the vacuum cleaner 502 is turned on and the harmful dust generated during polishing is sucked in through the dust collection bucket 507 by suction. The dust is absorbed and filtered by several layers of filter screens 506 inside the filter housing 504. When it is necessary to replace the filter screens 506, the filter screens 506 are replaced by opening and closing the switch door 505.

[0031] The control mechanism 6 includes a circuit board fixedly connected to the top of the fixed mounting frame 1. A wireless signal transceiver module 601 is fixedly connected to the top of the circuit board. A PLC controller 602 is fixedly connected to one side of the wireless signal transceiver module 601. A signal conversion module 603 is fixedly connected to one side of the PLC controller 602. An LCD touch screen 604 is fixedly connected to one side of the signal conversion module 603.

[0032] In practical use, when grinding the brake disc, it is necessary to collect data on the brake disc temperature, dynamic feed force during grinding, and surface smoothness of the brake disc. The data from the temperature sensor 305, pressure sensor 306, and laser rangefinder 409 are wirelessly transmitted through the wireless signal transceiver module 601. Then, the collected signals are converted by the signal conversion module 603 and displayed on the LCD touch screen 604 for viewing. The PLC controller 602 controls the electrical equipment of the drive structure.
