Description

Technical Field

[0001] The utility model relates to the technical field of brake disc processing, and more specifically to a brake disc processing and grinding device. Background Art

[0002] The brake disc is an important component in the automobile braking system. The brake disc is a round disc-shaped object that rotates with the car. In English, the brake disc is usually called "BRAKE DISC" or "BRAKE ROTORS". The brake disc achieves the braking effect through friction with the brake pad. When the brake pedal is pressed, the brake system makes the brake pad and the brake disc come into close contact, preventing the rotation of the tire through friction and converting energy into heat energy, thereby achieving deceleration or stopping.

If the processing and grinding device cannot be adjusted, then it can only process brake discs of fixed sizes, which will greatly limit the applicability and application scope of the device.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings of the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] A brake disc processing and grinding device comprises a fixed seat 1, a mounting frame 2 is fixedly mounted on the top of the fixed seat 1, a grinding wheel 4 is rotatably connected to the outer surface of the mounting frame 2, a fixing frame 11 is fixedly connected to the outer surface of the mounting frame 2 on the side close to the grinding wheel 4, a supporting frame 6 is arranged on the outer surface of the fixing frame 11, a fixing assembly for fixing brake discs of different sizes is arranged on the outer surface of the supporting frame 6, the fixing assembly comprises a pressure rod 7, a clamping block 8 and a through hole 9, the supporting frame 6 is arranged in an E-shaped structure, a through hole 9 for placing the center of the brake disc is opened at the center of the supporting frame 6, and the outer surfaces of both sides of the supporting frame 6 are rotatably connected to the pressure rod 7, The two pressure rods 7 are arranged in an L-shaped structure, and the other ends of the two pressure rods 7 are rotatably connected with blocks 8. The two blocks 8 are movably connected to the inside of the through hole 9. The interior of the mounting frame 2 is provided with a transmission component for driving the grinding wheel 4 to work. The brake disc is placed in the through hole 9 at the center of the support frame 6 to ensure that the center of the brake disc is aligned with the through hole 9. Subsequently, the two pressure rods 7 are operated to rotate around the outer surface of the support frame 6 until the two pressure rods 7 are located above the brake disc. Then, the two blocks 8 are rotated and moved accordingly until the two blocks 8 are located inside the brake disc and vertically downward, thereby achieving initial fixation of the brake disc.

[0024] Furthermore, two symmetrically distributed placement grooves 13 are provided on the outer surface of the support frame 6, and two symmetrically distributed connecting rods 10 are rotatably connected inside the support frame 6. The other ends of the two connecting rods 10 are movably connected to the corresponding internal placement grooves 13, so that the brake disc can be further fixed by adjusting the connecting rods 10. The two connecting rods 10 are rotated so that one end of them enters the placement groove 13, so that they contact the outer surface of the brake disc, thereby increasing the contact area and strengthening the support for the brake disc.

[0025] Furthermore, a slot 12 is provided on the outer surface of the fixing frame 11, and the interior of the slot 12 is movably connected to the support frame 6. A fastening nut 5 is movably connected to the outer surface of the fixing frame 11, and the fastening nut 5 is threadedly connected to the support frame 6. The position of the support frame 6 is moved in the slot 12 provided in the fixing frame 11. After the grinding position of the brake disc is determined, the fastening nut 5 on the outer surface of the fixing frame 11 is rotated to be threadedly connected to the support frame 6 and generate a fastening force, thereby ensuring the stability of the entire support frame 6.

[0026] Furthermore, a driving motor 3 is fixedly mounted on the outer surface of the mounting frame 2, and a first worm gear 14 is rotatably connected to the inside of the mounting frame 2. The driving motor 3 is fixedly connected to the first worm gear 14, and after the driving motor 3 is started, it drives the first worm gear 14 fixedly connected thereto to rotate.

[0027] Furthermore, the transmission assembly includes a first worm 15, a second worm wheel 16, and a second worm 17. The first worm 15 and the second worm 17 are rotatably connected inside the mounting frame 2. The outer surface of the first worm 15 is fixedly connected to the second worm wheel 16. The first worm 15 is meshingly connected to the first worm wheel 14, the second worm wheel 16 is meshingly connected to the second worm 17, and the second worm 17 is fixedly connected to the grinding wheel 4. The rotation of the first worm wheel 14 will drive the first worm 15 meshing therewith to rotate, thereby driving the second worm wheel 16 to rotate. The second worm wheel 16 is meshing with the second worm 17, so the rotation of the second worm wheel 16 will drive the second worm 17 to rotate synchronously. Since the second worm 17 is fixedly connected to the grinding wheel 4, the rotation of the second worm 17 will directly drive the grinding wheel 4 to work and grind the brake disc.

[0028] Furthermore, the grinding wheel 4 is located at the center of the support frame 6 to avoid dead angles during grinding.

[0029] Working principle: When the staff needs to use the brake disc processing and grinding device, first place the brake disc in the through hole 9 at the center of the support frame 6 to ensure that the center of the brake disc is aligned with the through hole 9. Then, operate the two pressure rods 7 to rotate around the outer surface of the support frame 6 until the two pressure rods 7 are located above the brake disc. Then rotate the two clamping blocks 8 to move accordingly until the two clamping blocks 8 are located inside the brake disc and vertically downward to achieve preliminary fixation of the brake disc. The brake disc can be further fixed by adjusting the connecting rod 10. Rotate the two connecting rods 10 so that one end of them enters the placement groove 13 so that it contacts the outer surface of the brake disc, increasing the contact area and thereby strengthening the support for the brake disc. After the brake disc is fixed on the support frame 6, move the support frame 6 in the slot 12 opened in the fixing frame 11. After the grinding position of the brake disc is determined, the fastening nut 5 on the outer surface of the fixing frame 11 is rotated to make it threadedly connected with the supporting frame 6 and generate a fastening force, so that the distance between the brake disc and the grinding wheel 4 can be adjusted. After the driving motor 3 is started, it drives the first worm gear 14 fixedly connected thereto to rotate. The rotation of the first worm gear 14 will drive the first worm 15 meshing therewith to rotate, and then drive the second worm gear 16 to rotate. The second worm gear 16 is meshed with the second worm 17, so the rotation of the second worm gear 16 will drive the second worm 17 to rotate synchronously. Since the second worm 17 is fixedly connected to the grinding wheel 4, the rotation of the second worm 17 will directly drive the grinding wheel 4 to work and grind the brake disc. After the processing is completed, turn off the driving motor 3, loosen the fixing assembly, and take out the processed brake disc.
