[0002] The brake disc is an important component of a car when braking. The quality of the car's braking performance directly affects the car's driving safety. The brake disc is actually a disc-shaped object with a round shape. When the car is driving, the brake disc rotates with the car's drive shaft. When the car brakes, the brake caliper clamps the two sides of the brake disc through the brake pads to generate braking force, thereby slowing down or stopping the car. At present, brake discs are usually manufactured in the form of casting to obtain an integrated structure.

[0020] The fixture mechanism includes two support rods 19, a cross bar 20, a flipping component and multiple sets of clamp assemblies. The two support rods 19 are symmetrically and vertically fixedly installed at the front end of the base 1, the cross bar 20 is horizontally arranged, and the two ends are respectively fixedly installed on the top of the two support rods 19, the flipping component is arranged on the cross bar 20, and the multiple sets of clamp assemblies are divided into two groups, which are centrally symmetrically arranged on the flipping component.

[0021] The flipping component includes two slides 21, four slide bars 22 and four handles 23. The upper and lower sides of the cross bar 20 are flat, and the front and rear sides are arc surfaces. A sliding opening 24 is opened in the middle of the two slides 21. The middle of the sliding opening 24 is a circular hole. The diameter of the circular hole is the same as the arc diameter of the cross bar 20. The slides 21 are slidably mounted on the cross bar 20 through the sliding opening 24. The four slide bars 22 are divided into two groups and are symmetrically and horizontally fixed on both sides of the two slides 21. The four handles 23 are respectively fixedly mounted on the ends of the two slides 21, and are symmetrically centered. Each group of clamp assemblies is arranged on two slide bars 22 in the same group.

[0022] The clamp assembly includes two support blocks 25, an insert block 26, two push blocks 27, two screw sleeves 28, a second screw 29, a worm 30 and a worm wheel 31. The two support blocks 25 in the middle group of clamp assemblies are respectively fixedly sleeved on the two slide bars 22, and the two support blocks 25 in the remaining clamp assemblies are respectively slidably sleeved on the two slide bars 22. The insert block 26 is fixedly installed on the top of the two support blocks 25, and the two push blocks 27 are symmetrically slidably installed in the insert block 26, and multiple push rods 271 are horizontally fixedly installed on the outer ends. The push rods 271 penetrate The two screw sleeves 28 are fixedly sleeved on the side walls of the insertion block 26, respectively, and are close to each other on the two push blocks 27. The second screw rod 29 is horizontally rotatably sleeved in the middle of the insertion block 26, and the two ends are respectively threadedly sleeved in the two screw sleeves 28. The worm wheel 31 is fixedly sleeved in the middle of the worm 30, and the worm 30 is vertically rotatably sleeved in the middle of the insertion block 26, and the end is meshed with the worm wheel 31. A spring 32 is sleeved between two adjacent support blocks 25 on the same slide rod 22, and the two ends of the spring 32 are respectively fixedly connected to the side of the two support blocks 25 close to each other.

[0023] When using this equipment to perform rough processing and grinding operations on brake discs, first, multiple brake discs are vertically placed on multiple sets of clamp assemblies, so that the bottom of the brake disc is stuck in the insert block 26, and then the worm 30 is rotated. The worm 30 drives the worm wheel 31 to rotate, and the worm wheel 31 drives the second screw 29 to rotate. The second screw 29 makes the two screw sleeves 28 move away from each other, thereby making the two push blocks 27 move away from each other, and multiple push rods 271 respectively clamp the inner wall of the brake disc to fix the brake disc.

[0024] After the brake disc is combined and fixed with the insert block 26, the two slide plates 21 are pulled by the two handles 23 to move, so that the cross bar 20 is combined with the circular hole in the middle of the slide 24, and then flipped upward to make the fixed brake disc flip to the lower side, and then the fixture mechanism is pushed to move multiple brake discs to between the two first grinding discs 2 and the multiple second grinding discs 3. Then the first motor 8 is started, and the driving wheel 11 drives the two driven wheels 10 to rotate through the transmission belt 13. The two first screws 4 rotate under the drive of the driven wheel 10, so that the multiple sliders 5 move, and the slider 5 drives the block 6 to move, and the block 6 drives the first grinding disc 2 and the second grinding disc 3 to move, and converge to the middle, pushing the multiple brake discs to gather to the middle, and compressing the spring 32 at the same time.

[0025] Finally, the inner sides of the two first grinding discs 2 and the two side sides of the multiple second grinding discs 3 respectively contact the two side sides of the multiple brake discs, and then the second motor 14 rotates, driving the transmission shaft 15 to rotate through the coupling, the transmission shaft 15 drives the multiple gears 17 to rotate, the gear 17 drives the ring gear 18 to drive the ring body 7 to rotate, and the ring body 7 drives the corresponding first grinding disc 2 and second grinding disc 3 to rotate, thereby realizing the rough processing and grinding operation of the brake disc.

[0026] Through the above method, the two first grinding wheels 2 and the multiple second grinding wheels 3 clamp the multiple brake discs and perform rough machining and grinding operations simultaneously, so that the two sides of the multiple second grinding wheels 3 work at the same time, and the two sides of the multiple brake discs are ground at the same time, thereby improving the efficiency of the rough machining operation.

[0027] After a group of brake discs completes the grinding operation, the first motor 8 starts to rotate in the reverse direction, causing the two first screws 4 to reverse, driving the multiple sliders 5 to disperse to both sides, thereby releasing the clamping force on the grinded brake discs. At the same time, the spring 32 recovers, and the multiple brake discs are separated. Then the flipping component is pulled again, so that the grinded brake discs exchange positions with the brake discs to be grinded, and enter the next grinding cycle.

[0028] With the cooperation of the jig mechanism, while a group of brake discs are being polished, the fixture assembly on the other side can be operated to unload the brake disc that has just completed the polishing operation, and then the brake disc to be polished can be loaded into the fixture assembly again and wait for polishing. In this way, loading and unloading can be carried out while polishing, shortening the operation cycle and further improving the efficiency of rough processing.

[0029] The cleaning mechanism includes a pipeline component, a suction device 33, a pump body device 34 and two solenoid valves 35. The suction device 33 and the pump body device 34 are fixedly installed on the upper side of the base 1, and the two solenoid valves 35 are fixedly installed on the output end of the pump body device 34 and the input end of the suction device 33 respectively.

[0030] The pipeline components include multiple sealing rings 36, multiple hoses 37, a cross pipe 38 and two frames 39. The first grinding disc 2 and the second grinding disc 3 are each provided with a cavity 40. The multiple sealing rings 36 are respectively embedded in the multiple cavities 40 for sealing and rotation. Multiple air holes 41 are respectively provided on the side where the two first grinding discs 2 are close to each other and on both sides of the multiple second grinding discs 3. The multiple air holes 41 are all connected to the cavity 40. The cross pipe 38 is horizontally fixedly installed on the upper side of the base 1 through two frames 39. The two ends of the multiple hoses 37 are respectively fixedly connected and communicated with the multiple sealing rings 36 and the cross pipe 38. The end of the hose 37 close to the sealing ring 36 is fixedly connected to the corresponding block 6 through a connecting frame 42. The output end of the pump body device 34 and the input end of the suction device 33 are respectively fixedly connected and communicated with the two ends of the cross pipe 38.

[0031] During the grinding process, the suction device 33, the pump device 34 and the two solenoid valves 35 operate alternately to clean the metal chips produced by grinding. After the brake disc contacts the first grinding disc 2 and the second grinding disc 3, the pump device 34 operates and the corresponding solenoid valve 35 is turned on, the suction device 33 is closed and the corresponding solenoid valve 35 is cut off, and the pump device 34 delivers the coolant into the multiple hoses 37 through the cross pipe 38. The coolant enters the multiple cavities 40 through the multiple hoses 37 and is finally discharged from the air holes 41 to cool the brake disc and then grind. Then, the pump device 34 stops and the corresponding solenoid valve 35 is cut off, the suction device 33 starts and the corresponding solenoid valve 35 is turned on to perform suction, and the metal chips produced by grinding enter the cavity 40 through the air holes 41, and then enter the hose 37 from the cavity 40, and then enter the cross pipe 38. Finally, the metal chips are sucked and discharged by the suction device 33, thereby achieving timely cleaning of the metal chips to avoid affecting the grinding operation.

[0032] The operation of the pump device 34 can cool the brake disc and dredge the pipeline components to ensure smooth suction operation.

[0033] Each electrical device is powered by an external power supply, and the entire device is controlled by a control terminal. Since the control terminal is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
