Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1:

[0026] As Figures 1-4 shown: It includes a U-shaped plate 1 and a clutch disc body 2. A chute 11 is opened in the middle of the top surface of the U-shaped plate 1, and a through hole 21 is opened in the middle of the clutch disc body 2. A grinding assembly 5 is arranged inside the chute 11. On the left and right sides above the U-shaped plate 1, a rotating assembly 3 and a limiting assembly 4 are respectively arranged. The rotating assembly 3 includes a first motor 31 fixedly installed on the left side wall of the U-shaped plate 1. The output end of the first motor 31 is fixedly installed in the middle of the side surface of a fixed disc 32. In the middle of the side of the fixed disc 32 away from the first motor 31, a sleeve column 33 with the same size as the through hole 21 is fixedly installed. The sleeve column 33 is movably sleeved inside the through hole 21. The limiting assembly 4 includes a hydraulic rod 41 fixedly installed on the right side wall of the U-shaped plate 1. The output end of the hydraulic rod 41 penetrates through the right side wall of the U-shaped plate 1 and is rotatably connected with a sleeve 42 through a bearing ring. An annular plate 44 is fixedly sleeved on the outer surface of one end of the sleeve 42 away from the hydraulic rod 41. A plug hole 43 with the same size as the sleeve column 33 is opened at one end of the sleeve 42 close to the annular plate 44. The sleeve column 33 is movably sleeved inside the plug hole 43. The diameters of the fixed disc 32 and the annular plate 44 are the same. When the sleeve column 33 passes through the through hole 21 and is inserted into the plug hole 43, both sides of the clutch disc body 2 are in close contact with the side walls of the fixed disc 32 and the annular plate 44 respectively. By sleeving the clutch disc body 2 outside the sleeve column 33, and then pushing the sleeve 42 and the annular plate 44 to move towards the side of the rotating assembly 3 through the hydraulic rod 41, the sleeve column 33 is inserted into the plug hole 43. Subsequently, the fixed disc 32 and the annular plate 44 will contact both sides of the clutch disc body 2, and the clutch disc body 2 can be clamped and fixed. Then, the grinding disc 54 is adjusted to both sides of the clutch disc body 2, and the grinding disc 54 is kept in contact with the side surface of the clutch disc body 2. Subsequently, the first motor 31 drives the fixed disc 32 to rotate, and then drives the clutch disc body 2 to rotate synchronously. Subsequently, both sides of the clutch disc body 2 are polished and ground by the grinding disc 54. This avoids the situation where the clutch disc body 2 moves randomly, can make the grinding effect on both sides of the clutch disc body 2 more average, and is beneficial to improving the grinding effect on the clutch disc body 2;

[0027] Embodiment 2:

[0028] As Figures 1-2As shown in the figure: The grinding assembly 5 includes a second motor 51 fixedly installed on the side wall of the sliding groove 11. One end of a threaded rod 52 is fixedly connected to the output end of the second motor 51, and the other end of the threaded rod 52 is rotatably sleeved on the side wall of the sliding groove 11 through a bearing ring. Two sliders 53 with opposite thread directions are threadedly sleeved on the outer surface of the threaded rod 52. Grinding discs 54 are provided at the tops of the two sliders 53. The tops of the two sliders 53 are fixedly installed on the arc surface of the grinding disc 54. A relief hole 55 with the same size as the fixed disc 32 and the annular plate 44 is opened in the middle of the side surface of the grinding disc 54. The fixed disc 32 and the grinding disc 54 are respectively movably sleeved inside the relief holes 55 at their adjacent positions. By driving the threaded rod 52 to rotate through the second motor 51, the sliders 53 can be driven to move inside the sliding groove 11, and then the grinding discs 54 are moved to both sides of the clutch disc body 2, enabling the grinding discs 54 to contact the side surfaces of the clutch disc body 2, achieving the purpose of allowing the grinding discs 54 to grind clutch disc bodies 2 with different thicknesses, and having a wide range of applications.

[0029] The working principle and usage process of the present utility model: For this double-sided polishing device of the clutch disc, during use, the clutch disc body 2 is sleeved outside the sleeve column 33, and then the hydraulic rod 41 is started to push the sleeve 42 and the annular plate 44 towards the side of the rotating assembly 3. During the movement of the sleeve 42 and the annular plate 44, the sleeve column 33 will be inserted into the insertion hole 43, and then the fixed disc 32 and the annular plate 44 will contact both sides of the clutch disc body 2, thereby clamping and fixing the clutch disc body 2. Then, the second motor 51 is started to drive the threaded rod 52 to rotate, which can drive the sliders 53 to move inside the sliding groove 11, and then move the grinding discs 54 to both sides of the clutch disc body 2, keeping the grinding discs 54 in contact with the side surfaces of the clutch disc body 2. Then, the first motor 31 is started to drive the fixed disc 32 to rotate. Since the sleeve 42 is rotatably connected to the output end of the hydraulic rod 41 through a bearing ring, the fixed disc 32, the sleeve column 33, the clutch disc body 2, the annular plate 44, and the sleeve 42 will rotate around the sleeve column 33, and then the two sides of the clutch disc body 2 are polished and ground through the grinding discs 54.
