The rotating motor 103 is used to provide power to change the inclination angle of the inclined platform 102; a first connecting rod 104 is arranged in the middle of the inclined platform 102, and the inclined platform 102 is bolted to the first connecting rod 104. The first connecting rod 104 is used to fix the friction plate fixture 2.

[0023] Please refer to Figure 4, in this embodiment, the friction plate fixture 2 includes a bearing platform 201, a guide groove 202, a cylinder fixture 203, and a processing hole 204; a guide groove 202 is provided above the bearing platform 201, and the bearing platform 201 and the guide groove 202 are integrally formed. The bearing platform 201 is used to place the friction plate to be processed; a cylinder fixture 203 is provided above the bearing platform 201, and the bearing platform 201 and the cylinder fixture 203 are bolted. The cylinder fixture 203 is used to fix the friction plate to be processed; a processing hole 204 is provided in the middle of the bearing platform 201, and the bearing platform 201 and the processing hole 204 are integrally formed. The processing hole 204 can make the grinding of the central through hole of the friction plate more convenient and improve the grinding efficiency at the same time.

[0024] Please refer to Figure 5 , in this embodiment, the cylinder fixture 203 includes a fixing member 2031, a second cylinder 2032, and a clamping member 2033; a second cylinder 2032 is provided above the fixing member 2031, and the fixing member 2031 and the second cylinder 2032 are bolted. The fixing member is used to prevent the second cylinder 2032 from moving and reducing the grinding accuracy. The second cylinder 2032 is used to provide the power required to clamp the friction plate to be processed; a clamping member 2033 is provided inside the second cylinder 2032, and the clamping member 2033 is connected to the power output end of the second cylinder 2032. The clamping member 2033 is used to contact the friction plate to be processed and provide frictional force to prevent the friction plate from moving during the grinding process.

[0025] Please refer to Figure 6 , in this embodiment, the cooling device 3 includes a second connecting rod 301, a first cylinder 302, a cooling nozzle 303, and an input port 304; a first cylinder 302 is provided at the end of the second connecting rod 301, and the second connecting rod 301 and the first cylinder 302 are flange-connected. The second connecting rod 301 is used to fix the first cylinder 302 directly below the processing hole 204. The first cylinder 302 is used to provide the power required to spray the coolant; a cooling nozzle 303 is provided above the first cylinder 302, and the cooling nozzle 303 is connected to the output end of the first cylinder 302. The cooling nozzle 303 is used to adjust the direction of the coolant spray to achieve a better cooling effect for the friction plate to be processed; an input port 304 is provided below the first cylinder 302, and the input port 304 is connected to the input end of the first cylinder 302. The input port 304 is used to provide the coolant required during the grinding process.

[0026] When working, first place the friction plate to be polished on the bearing platform 201 and above the processing hole 204. Then connect the input end of the coolant to the input port 304. Next, the power output end of the second cylinder 2032 drives the clamping member 2033 to converge along the guide groove 202 towards the center of the processing hole 204. When the pressure value received by the cylinder fixture 203 reaches the value capable of firmly fixing the friction plate on the bearing platform 201, the second cylinder 2032 stops outputting and the position of the clamping member 2033 is fixed, preventing the friction plate from generating displacement. During the processing, the coolant passes through the input port 304, is pressurized by the first cylinder 302, and sprays out from the cooling nozzle 303. The coolant contacts the friction plate to be processed through the processing hole 204, reducing the temperature of the friction plate and preventing the friction plate from being damaged due to overheating;

[0027] If it is necessary to adjust the processing angle to facilitate the CNC chamfering and grinding structure to perform chamfering and grinding on the edge of the hole diameter at a matching chamfering angle, then the power output end of the rotating motor 103 drives the inclined platform 102 to rotate. The first connecting rod 104 on the inclined platform 102 drives the friction plate fixture 2 to change the inclination angle so that the friction plate reaches a suitable angle for polishing and processing.

[0028] Through the above steps, the inclination angle of the friction plate fixture is adjusted by the installation frame to solve the problem that the fixture for fine machining of the existing friction plate may not be able to completely remove the burr protrusions on the inner wall of the hole on the friction plate due to the angle during the grinding of the inner wall of the hole on the friction plate, resulting in loosening when the friction plate is fixed by bolts. The problem of overheating and damage of the friction plate during processing is also prevented by the cooling device.

[0029] The above has described the embodiments of the present invention in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
