Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figure 1 shown, a double-sided grinding device includes a workbench 1. A through groove 2 is formed through the upper surface of the workbench 1. A clamping mechanism 3 for clamping a workpiece is arranged inside the through groove 2. Support plates 4 are installed on both the upper and lower surfaces of the workbench 1. A grinding mechanism 5 is arranged on one side of each support plate 4. Support legs 6 are installed at the four corners of the lower surface of the workbench 1.

[0023] As Figure 2 , Figure 3 shown, a first installation groove 101 is formed on the upper surface of the workbench 1. The clamping mechanism 3 includes a first driving motor 301. The first driving motor 301 is installed on one end surface of the workbench 1 and on one side of the first installation groove 101. The output end of the first driving motor 301 is installed with a first bidirectional lead screw 302. One end of the first bidirectional lead screw 302 is rotatably arranged on the inner wall of one end of the first installation groove 101. First lead screw sleeves 303 are movably installed on both side rods of the first bidirectional lead screw 302. A connecting frame 304 is installed on the top of each first lead screw sleeve 303. An arc-shaped clamping plate 305 is installed at one end of each connecting frame 304. The two arc-shaped clamping plates 305 are respectively arranged on both sides inside the through groove 2.

[0024] Through the meshing drive between the first bidirectional lead screw 302 and the first lead screw sleeve 303, driven by the first drive motor 301, the arc-shaped clamping plate 305 can be controlled to move, so as to clamp and fix the lens, facilitating the grinding work.

[0025] As Figure 3 , Figure 4 shown, a second installation groove 401 is formed on one side surface of each support plate 4. The grinding mechanism 5 includes a second drive motor 501. The second drive motor 501 is installed on the top of the upper support plate 4. The output end of the second drive motor 501 is installed with a second bidirectional lead screw 502. One end of the second bidirectional lead screw 502 penetrates through the workbench 1 and is rotatably arranged on the bottom inner wall of the lower second installation groove 401. Second lead screw sleeves 503 are installed on both side rod bodies of the second bidirectional lead screw 502 and inside each second installation groove 401. One end of each second lead screw sleeve 503 is provided with a mounting plate 504. A servo motor 505 is installed on one side surface of each mounting plate 504. The output end of each servo motor 505 is installed with a rotating rod 506. One end of each rotating rod 506 penetrates through the mounting plate 504 and a grinding wheel 507 is installed at the end.

[0026] Through the meshing drive between the second bidirectional lead screw 502 and the second lead screw sleeve 503, driven by the second drive motor 501, the two grinding wheels 507 can be controlled to move simultaneously to adjust their heights, facilitating the grinding work of different lenses and being able to grind the two side surfaces simultaneously, effectively improving the processing efficiency.

[0027] The working principle of this double-sided grinding device:

[0028] During use, the first driving motor 301 drives the first bidirectional lead screw 302 to rotate. Under the meshing action between the first bidirectional lead screw 302 and the first lead screw sleeve 303, the first lead screw sleeve 303 can drive the connecting frame 304 to move, thereby controlling the two arc-shaped clamping plates 305 to move in opposite directions, and clamping and fixing the lens to be polished. The second driving motor 501 drives the second bidirectional lead screw 502 to rotate. Under the meshing action between the second bidirectional lead screw 502 and the second lead screw sleeve 503, the two mounting plates 504 can be controlled to move in opposite directions, thereby adjusting the distance between the two grinding wheels 507. The grinding wheel 507 is moved above the lens. The servo motor 505 drives the rotating rod 506 to rotate, driving the grinding wheel 507 to rotate to polish the lens. The two grinding wheels 507 are symmetrically arranged. By using the meshing action between the second bidirectional lead screw 502 and the second lead screw sleeve 503, they can be controlled to move simultaneously, so that the two sides of the lens can be polished simultaneously. The operation is convenient, the processing time is saved, and the processing efficiency is higher.

[0029] Obviously, the above-mentioned embodiments of the present utility are merely examples for clearly explaining the present utility, rather than limitations on the implementation manners of the present utility. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present utility are still within the protection scope of the present utility.
