Description

Technical Field

[0001] This utility model relates to the field of optical lens polishing technology, and in particular to an adjustable fine polishing device for optical lenses. Background Technology

[0002] In the manufacturing process of optical lenses, fine grinding and polishing is a key step that determines the optical performance and surface quality of the lens. Traditional adjustable fine grinding and polishing devices usually adopt a fixed pressure adjustment structure. The core principle is to apply constant pressure to the lens through elastic elements such as springs. However, this traditional design has revealed significant defects in practical applications.

[0003] When processing optical lenses of different thicknesses, the compression of the spring in the pressure device changes due to the difference in lens thickness. This results in a significant deviation in the actual pressure applied to the lens surface. For thinner lenses, insufficient spring compression may lead to insufficient pressure, which cannot effectively remove surface defects. For thicker lenses, excessive spring compression will generate excessive pressure, causing scratches on the lens surface. This pressure instability directly leads to significant differences in the polishing effect of lenses of different thicknesses within the same processing time.

[0004] Therefore, a device that can adjust the polishing pressure is needed to solve the problem of uniform polishing of lenses of different thicknesses and avoid the problem of unstable pressure affecting product consistency and yield. Utility Model Content

[0005] In view of the above-mentioned need for a device that can adjust the polishing pressure to solve the problem of uniform polishing of lenses of different thicknesses and avoid the problem of unstable pressure affecting product consistency and yield, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to place the optical lens to be polished in the polishing worktable, and use the rotating handle on one side of the plug-in fixing post, wherein the rotating handle is provided with a fixing rod. Moving the rotating handle upwards causes the fixing rod to be released from the constraint and rotate, thereby controlling the raising and lowering of the fixing stud. This ensures that the pressure of the limiting pressing block on the optical lenses to be polished of different thicknesses is similar. Then, the fixing rod is inserted into the nearest positioning constraint groove, so that the pressure of optical lenses of different thicknesses can be adjusted during polishing, thereby ensuring the yield rate of the product and effectively improving the efficiency of the factory.

A limiting stud 3 is provided on one side of the fixed limiting plate 2, and an internal thread 4 is provided on the inner side of the limiting stud 3. The device includes a fixed stud 5 provided on the inner side of the polishing worktable 1, a guide fixing plate 8 provided on the inner side of the fixed stud 5, a limiting connecting rod 11 provided on one side of the guide fixing plate 8, and a limiting pressing block 12 on one side of the limiting connecting rod 11. The fixed stud 5 is sleeved on the inner side of the limiting stud 3 and connected to the internal thread 4 by the thread. A guide constraint groove 6 is provided on the inner side of the fixed stud 5, and a guide constraint post 7 is provided on the inner side of the guide constraint groove 6.

[0032] A guide fixing plate 8 is provided inside the guide constraint groove 6, and a guide sleeve 9 is provided on one side of the guide fixing plate 8. The guide sleeve 9 is sleeved on the outside of the guide constraint post 7. A reset spring 10 is provided inside the guide constraint groove 6, and the reset spring 10 is sleeved on the outside of the guide sleeve 9. A limiting connecting rod 11 is provided on one side of the guide fixing plate 8. One end of the limiting connecting rod 11 passes through the fixing stud 5 and is located inside the polishing worktable 1. A limiting pressing block 12 is provided on one side of the limiting connecting rod 11, and a fixing connecting plate 13 is provided on one side of the fixing stud 5.

[0033] Example 2

[0034] Reference Figure 3-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that it includes a fixed connecting plate 13 on one side of the fixed stud 5, a plug-in limiting post 14 on one side of the fixed connecting plate 13, a plug-in fixing post 17 on the inner side of the plug-in limiting post 14, and a rotating handle 19 on one side of the plug-in fixing post 17. The fixed connecting plate 13 has a plug-in limiting post 14 on one side, and a plug-in limiting groove 15 is opened on the inner side of the plug-in limiting post 14. A rotating connecting groove 21 is opened on the polishing worktable 1, and the plug-in limiting post 14 is located inside the rotating connecting groove 21.

[0035] A hexagonal limiting plate 16 is provided inside the insertion limiting groove 15. An insertion fixing post 17 is provided on one side of the hexagonal limiting plate 16. The insertion fixing post 17 is suspended through the insertion limiting post 14 on one side. A constraint spring 18 is provided on one side of the hexagonal limiting plate 16. The constraint spring 18 is sleeved on the insertion fixing post 17. A rotating handle 19 is provided on one side of the insertion fixing post 17. A fixing rod 20 is provided on one side of the rotating handle 19. Multiple positioning constraint grooves 22 are opened on one side of the polishing worktable 1. One end of the fixing rod 20 is inserted into the inner side of the corresponding positioning constraint groove 22. A polishing wheel 23 is provided inside the polishing worktable 1. An optical lens to be polished is provided between the polishing wheel 23 and the limiting pressing block 12.

[0036] In use, depending on the thickness of the optical lens to be polished, rotate the handle 19 to rotate the fixing stud 5. Since the fixing stud 5 and the limiting stud 3 are connected by threads, when the fixing stud 5 is rotated, it will move along the axial direction of the limiting stud 3, causing the guide fixing plate 8 to move up and down with the movement of the fixing stud 5. The guide fixing plate 8 has a limiting connecting rod 11 on one side and a limiting pressing block 12 on the other side. When the guide fixing plate 8 moves up and down, it will drive the limiting connecting rod 11 and the limiting pressing block 12 to move up and down synchronously.

[0037] After lifting the limiting press block 12 by hand, place the optical lens to be polished in the polishing worktable 1, between the polishing wheel 23 and the limiting press block 12. The reset spring 10 is sleeved on the outside of the guide sleeve 9 to reset the limiting press block 12, so that it continues to apply pressure to the lens. Then, using the rotating handle 19 on one side of the insertion fixing post 17, which has a fixing rod 20 on one side, move the rotating handle 19 upward to make the fixing rod 20 unconstrained and rotate, thereby controlling the rise and fall of the fixing stud 5, so that the pressure of the limiting press block 12 on optical lenses of different thicknesses is similar. Then, insert the fixing rod 20 into the nearest positioning constraint groove 22 to complete the fixing operation.

[0038] After pressure adjustment and locking are completed, the polishing device is started, and the polishing wheel 23 begins to rotate. During the rotation, the polishing wheel 23 contacts the lens surface and performs fine polishing on the lens. The limiting pressing block 12 continuously applies stable pressure to the lens to ensure that the lens can be polished evenly by the polishing wheel 23 throughout the polishing process, thereby improving the polishing effect, avoiding the problem of different polishing effects caused by unstable pressure, and ensuring the polishing quality and consistency of lenses of different thicknesses.

[0039] The remaining structure is the same as that in Example 1.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
