Detailed implementation mode

[0018] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: an optical crystal surface grinding and processing device, including a grinding table 1, the inner side of the grinding table 1 is rotationally connected with a grinding wheel, a fixed clamp 12 is arranged on one side of the grinding wheel, and further includes an adjusting sleeve 13, a lead screw 16, a magnet 23 and a Hall sensor 24. One end of the adjusting sleeve 13 is fixedly connected to the middle of one side of the fixed clamp 12. A sliding groove 14 is horizontally opened inside the grinding table 1 on the side far from the grinding wheel. A slide block 17 is slidably connected inside the sliding groove 14. One end of the adjusting sleeve 13 placed inside the sliding groove 14 penetrates through the slide block 17 and is fixedly connected to the slide block 17. A connecting groove 15 is opened on one side of the sliding groove 14. One end of the lead screw 16 is rotationally connected to the upper part of the inner wall of one side of the connecting groove 15 through a bearing. The other end of the lead screw 16 is threadedly connected to the adjusting sleeve 13. The lead screw 16 and the adjusting sleeve 13 are matched with the size of the sliding groove 14. One side of the lead screw 16 placed inside the connecting groove 15 penetrates through the middle of the large gear 18 and is fixedly connected to the large gear 18. A second driving motor 3 is fixedly connected inside the other side of the grinding table 1. The shaft end of the second driving motor 3 is fixedly connected to the grinding wheel through the second connecting rod 31. The front and rear sides of the fixed clamp 12 penetrate and are threadedly connected with a screw rod 32. One end of the screw rod 32 placed inside the fixed clamp 12 is fixedly installed with a fixed block 33.

[0019] In this technical solution, by rotating the screw rods 32 on the front and rear sides of the fixed clamp 12, the fixed block 33 can be pushed to clamp the optical crystal inside the fixed clamp 12, so that the grinding surface of the optical crystal faces the grinding surface of the grinding wheel 11. Through the threaded connection between the lead screw 16 and the adjusting sleeve 13, and the sliding connection between the slide block 17 and the sliding groove 14, when the lead screw 16 rotates, the slide block 17 can push the fixed clamp 12 at one end of the adjusting sleeve 13 to move left and right, so as to push the optical crystal to fit with the grinding wheel 11. Then, control the second driving motor 3 to work, and the grinding wheel 11 can be driven to rotate through the second connecting rod 31 for grinding operation.

[0020] In this embodiment, a first driving motor 2 is fixedly connected to the lower part of the inner wall of one side of the connecting groove 15. The shaft end of the first driving motor 2 is fixedly connected to a first connecting rod 21. One end of the first connecting rod 21 is fixedly installed with a small gear 22. The small gear 22 meshes with the large gear 18, and the small gear 22 is matched with the size of the large gear 18.

[0021] In this technical solution, the first driving motor 2 is controlled by a corresponding controller to operate. The first connecting rod 21 can drive the pinion gear 22 to rotate, and the large gear 18 can drive the lead screw 16 to rotate slowly, and further can push the optical crystal inside the fixed clamp 12 to move slowly to the left.

[0022] In this embodiment, the magnetic steel 23 is fixedly connected to the outer side of the first connecting rod 21, and the Hall sensor 24 is fixedly installed on the bottom inner wall of the connecting groove 15. The Hall sensor 24 corresponds to the magnetic steel 23, and the magnetic steel 23 is evenly distributed in a ring shape on the outer side of the first connecting rod 21.

[0023] In this technical solution, during the rotation of the first connecting rod 21, the magnetic steel 23 can be driven to rotate. When the magnetic steel 23 rotates to the bottom end of the first connecting rod 21 and aligns with the Hall sensor 24, the Hall sensor 24 can transmit data to the corresponding controller, and further can detect the number of rotations of the first connecting rod 21, thereby detecting the number of rotations of the lead screw 16 and the displacement of the fixed clamp 12 at one end of the adjusting sleeve 13, so as to solve the problem that the existing optical crystal surface grinding device is inconvenient to control the grinding amount of the optical crystal and affects the grinding accuracy.

[0024] When an optical crystal surface grinding device is in use, rotate the screws 32 on the front and rear sides of the fixed clamp 12, which can push the fixed block 33 to clamp the optical crystal inside the fixed clamp 12, so that the grinding surface of the optical crystal faces the grinding surface of the grinding wheel 11. The first driving motor 2 is controlled by a corresponding controller to operate. The first connecting rod 21 can drive the pinion gear 22 to rotate, and the large gear 18 can drive the lead screw 16 to rotate slowly. Since the lead screw 16 is threadedly connected to the adjusting sleeve 13 and the slider 17 is slidably connected to the sliding groove 14, during the rotation of the lead screw 16, the slider 17 can push the fixed clamp 12 at one end of the adjusting sleeve 13 to move left and right, so as to push the grinding surface of the optical crystal to fit with the grinding wheel 11. Then control the second driving motor 3 to operate, and the second connecting rod 31 can drive the grinding wheel 11 to rotate for grinding operations. During the rotation of the first connecting rod 21, the magnetic steel 23 can be driven to rotate. When the magnetic steel 23 rotates to the bottom end of the first connecting rod 21 and aligns with the Hall sensor 24, the Hall sensor 24 can transmit data to the corresponding controller, and further can detect the number of rotations of the first connecting rod 21, thereby detecting the number of rotations of the lead screw 16 and the displacement of the fixed clamp 12 at one end of the adjusting sleeve 13, so as to solve the problem that the existing optical crystal surface grinding device is inconvenient to control the grinding amount of the optical crystal and affects the grinding accuracy.
