The rotating shaft 111 is driven to rotate by the rotating component 113, thereby driving the eccentric wheel 112 to rotate, so that the abutment plate 108 is lifted and lowered under the action of the eccentric wheel 112 and the spring 110, thereby driving the lifting frame 109 and the grinding wheel 103 to lift and lower, thereby adjusting the polishing pressure. The above-mentioned scheme can be used when adjusting the polishing pressure, and can also be used when tensioning the polishing belt 104.

When the eccentric wheel 112 rotates, its rotation center and geometric center do not coincide, so that the eccentric wheel 112 drives the abutment plate 108 to descend, thereby driving the lifting frame 109, the grinding wheel 103 and the polishing belt 104 to descend. When the polishing pressure needs to be reduced, the rotating component 113 drives the rotating shaft 111 to rotate in the opposite direction. At this time, the abutment plate 108 rises under the action of the spring 110 and presses against the eccentric wheel 112, thereby driving the lifting frame 109 and the grinding wheel 103 to rise, thereby reducing the polishing pressure on the optical element. By controlling the angle of the eccentric wheel 112 through the rotating component 113, the polishing pressure can be accurately adjusted, thereby achieving the purpose of improving the polishing pressure adjustment accuracy.

[0029] Secondly, the connecting rod 114 is fixedly connected to the abutment plate 108 and is located on a side of the abutment plate 108 close to the spring 110; the top plate 115 is fixedly connected to the connecting rod 114 and is located at an end of the connecting rod 114 away from the abutment plate 108; the first pressure sensor 116 is fixedly connected to the top plate 115 and is located on one side of the top plate 115; the first mounting bracket 117 is fixedly connected to the first pressure sensor 116 and is rotatably connected to the grinding wheel 103 and is located on a side of the first pressure sensor 116 away from the top plate 115; the first pressure sensor 116 is fixedly connected to the first pressure sensor 116 and is rotatably connected to the grinding wheel 103 and is located on a side of the first pressure sensor 116 away from the top plate 115; 6 is electrically connected to the rotating component 113.

The pressure applied by the top plate 115 to the first mounting frame 117, the grinding wheel 103 and the polishing belt 104 is detected by the first pressure sensor 116, and then the polishing pressure is monitored in real time, and the operation of the rotating component 113 is controlled to adjust the angles of the rotating shaft 111 and the eccentric wheel 112, so as to control the polishing pressure with high precision.

[0030] At the same time, the worm wheel 118 is fixedly connected to the rotating shaft 111 and is sleeved on the rotating shaft 111; the worm 119 is rotatably connected to the housing 107, meshes with the worm wheel 118, and is located inside the housing 107; the servo motor 120 is connected to the housing 107 and is located on one side of the housing 107, and the output end of the servo motor 120 is connected to the worm 119; the servo motor 120 drives the worm 119 to rotate forward and reverse, and then drives the worm wheel 118 to rotate forward and reverse, and the worm wheel 118 drives the rotating shaft 111 and the eccentric wheel 112 to rotate forward and reverse, thereby driving the rotating shaft 111 to rotate, and at the same time, the self-locking property between the worm wheel 118 and the worm 119 improves the stability of the rotating shaft 111 and the eccentric wheel 112.

When the polishing pressure is too large or too small, the servo motor 120 drives the worm 119 to rotate, and then drives the worm wheel 118 to rotate, so that the worm wheel 118 drives the rotating shaft 111 and the eccentric wheel 112 to rotate, and then the abutment plate 108 is lifted and lowered under the action of the spring 110 and the eccentric wheel 112, thereby driving the lifting frame 109 and the grinding wheel 103 to lift and lower, and adjusting the pressure applied by the grinding wheel 103 to the optical element, so as to achieve the purpose of accurately adjusting the polishing pressure.
