DETAILED DESCRIPTION
[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0025] Embodiment 1
[0026] As Figures 1-5 As shown, this utility model provides a grinding device for processing automotive brake pads, including a grinding device body 1. The grinding device body 1 includes a grinding box 2. Support brackets 3 are welded to the top two sides of the grinding box 2. A dust collection box 4 is fixedly installed on the bottom of the grinding box 2. A placement groove 21 is opened on the bottom of the interior of the grinding box 2. A dustproof mechanism is provided above the grinding box 2. Dust suction mechanisms are provided on both sides of the grinding box 2. The dustproof mechanism includes a dust cover 32 movably installed above the grinding box 2. Telescopic connecting rods 31 are fixedly installed on all four sides of the top of the dust cover 32. The other end of the telescopic connecting rods 31 is fixedly installed at the top and bottom of the support brackets 3. A motor 3 is fixedly installed in the middle of the top of the dust cover 32. 3. The output end of motor 1 33 extends into the interior of dust cover 32 and is fixedly connected to grinding disc 34. Limiting vertical rods 35 are fixedly installed in the grooves on both sides of the support bracket 3. Motor 2 36 is fixedly installed at the top of the groove. Threaded rod 37 is fixedly installed on the output end of motor 2 36. Moving block 38 is movably sleeved on the outer surface of threaded rod 37. The inner end of moving block 38 is fixedly installed in the middle position on both sides of dust cover 32. Both sides of moving block 38 are slidably sleeved on the outer surface of limiting vertical rod 35. Sliding grooves 39 are opened on both sides of the left and right side frames of support bracket 3 on both sides of the groove. Sliding slider 310 is slidably connected inside the sliding groove 39. Sliding slider 310 is fixedly installed on the outer surfaces of both sides of dust cover 32.
[0027] Furthermore, the output end of motor 2 36 drives the threaded rod 37 to rotate at a constant speed, causing the moving block 38 on its outer surface to gradually move downward, thereby driving the dust cover 32 to move downward until it touches the top of the grinding box 2. In conjunction with the output end of motor 1 33, the grinding disc 34 rotates at a constant speed to facilitate the grinding of burrs on the outer surface of the brake pad. During grinding, the dust cover 32 can prevent the flying debris and powder from spreading to the surrounding area.
[0028] Example 2
[0029] like Figures 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the dust collection mechanism includes dust collection ports 22 opened on both sides of the grinding box 2. A support frame 23 is fixedly installed on the inner wall of the dust collection port 22. A helical gear 24 is fixedly sleeved on the other end of the threaded rod 37 inside the dust collection port 22. A helical gear 25 is meshed on one side of the teeth of the helical gear 24. The output end of the helical gear 25 passes through the support frame 23 and is fixedly sleeved with a dust collection fan 26. A dust collection hood 27 is fixedly installed on the output end of the dust collection port 22. A dust guide pipe 28 is fixedly installed on the other end of the dust collection hood 27. The other end of the dust guide pipe 28 is fixedly installed inside both sides of the dust collection box 4.
[0030] Furthermore, after grinding, the threaded rod 37 rotates again, causing the dust cover 32 to move upward and reset. When the threaded rod 37 rotates, it drives the first helical gear 24 and the second helical gear 25 to rotate as well. The output end of the second helical gear 25 drives the vacuum fan 26 to rotate as well. The rotation of the vacuum fan 26 generates suction to easily suck up the debris and powder inside. Together with the vacuum cover 27 and the dust guide tube 28, it can collect them uniformly inside the dust collection box 4 for easy unified processing later.
[0031] The working principle of this grinding device for processing automotive brake pads will be explained in detail below.
[0032] like Figures 1-5 As shown, during use, the brake pads to be ground are placed in the placement slot 21 inside the grinding box 2. The output end of motor 2 36 drives the threaded rod 37 to rotate at a constant speed, causing the moving block 38 on its outer surface to gradually move down, which in turn drives the dust cover 32 to move down until it touches the top of the grinding box 2. The output end of motor 1 33 drives the grinding disc 34 to rotate at a constant speed to facilitate the grinding of burrs on the outer surface of the brake pads. During grinding, the dust cover 32 can prevent the flying debris and powder from spreading to the surrounding area. After grinding, the threaded rod 37 rotates again to drive the dust cover 32 to move up and reset. When the threaded rod 37 rotates, it drives the helical gear 1 24 and helical gear 25 to rotate as well. The output end of helical gear 25 drives the dust suction fan 26 to rotate as well. The rotation of the dust suction fan 26 generates suction to facilitate the suction of debris and powder inside. With the help of the dust suction cover 27 and the dust guide pipe 28, the debris and powder can be collected in the dust collection box 4 for easy processing later.
[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
