Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, specifically a clamping device for optical lens processing. Background Technology

[0002] Optical lenses, as core components of optical systems, play an irreplaceable role in numerous fields. In the consumer electronics sector, the widespread adoption and continuous upgrading of devices such as smartphones, tablets, and digital cameras have placed higher demands on the performance and quality of optical lenses. As these industries continue to raise their performance requirements for optical lenses, the processing precision and surface quality of optical lenses have become key indicators. In the processing of optical lenses, the clamping device is a crucial link in ensuring processing quality.

[0003] According to Chinese Patent Publication No. CN222589506U, a clamping device for optical lens processing is disclosed. By placing the optical lens inside a positioning ring, the optical lens can be quickly positioned. Then, a motor drives a rotating rod to rotate, causing an incomplete gear to drive a spur gear on one side to rotate. This causes the first internal threaded tube to rotate, which in turn moves the first threaded rod that cannot rotate, causing the pressure block to move down. This, in conjunction with the worktable, clamps the optical lens. Then, the incomplete gear drives the spur gear on the other side to rotate, causing the second internal threaded tube to move the second threaded rod that cannot rotate up. This allows the positioning ring to move up, exposing the edge of the optical lens, which facilitates stable processing of the optical lens.

[0004] However, the current technical solution can only clamp and fix the lens from the top of the lens using a clamping block, which means that only the edge of the lens can be processed. When the surface of the lens needs to be processed, another clamping and fixing device needs to be replaced, which has certain limitations and affects the processing efficiency of the lens. Therefore, we propose a clamping device for optical lens processing. Utility Model Content

[0005] The purpose of this invention is to provide a clamping device for optical lens processing, which solves the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for optical lens processing, comprising a base plate and a movable plate.

[0026] like Figure 1-7As shown, this utility model provides a technical solution: a clamping device for optical lens processing, including a base plate 1 and a movable plate 5. A support plate 2 is fixedly installed at the top of the base plate 1, and a top plate 3 is fixedly installed at the top of the support plate 2. A driving structure is connected to the top of the movable plate 5. A fixing port 6 is opened on the movable plate 5, and a clamping block 7 is connected to the inner wall of the fixing port 6. A connecting frame 19 is connected to the bottom of the movable plate 5, and the connecting frame 19 is slidably connected to the outer wall of the movable plate 5. A pressure block 20 is fixedly installed at the bottom of the connecting frame 19. A support column 21 is fixedly installed at the top of the base plate 1, and a support block 22 is fixedly installed at the top of the support column 21.

Fastening screws 23 are threadedly connected to the threaded holes on the front and back of the connecting frame 19, and the fastening screws 23 are threadedly connected to the threaded holes on the connecting block 24.

[0027] Furthermore, a threaded sleeve 9 is fixedly installed on the outer side of the clamping block 7, and a shrinkage groove 8 is opened on the inner wall of the fixing port 6. The threaded sleeve 9 is inserted into the shrinkage groove 8. A rotating groove 11 is opened on the moving plate 5. A drive screw 10 passes through the inner wall of the rotating groove 11, and the drive screw 10 is rotatably connected to the moving plate 5 through a bearing. The threaded sleeve 9 is located on the outer wall of the drive screw 10. A gear 12 is provided in the rotating groove 11. The gear 12 is fixedly installed at one end of the drive screw 10. A ring plate 27 is rotatably connected to the top of the moving plate 5. A toothed ring 13 is fixedly installed at the bottom of the ring plate 27. The gear 12 meshes with the toothed ring 13.

[0028] By setting the gear ring 13, four gears 12 can be rotated simultaneously through the gear ring 13, thereby ensuring the accuracy of the lens compression and fixing position.

[0029] Furthermore, the top of the movable plate 5 is connected to the rotating groove 11 and has an annular groove 18. The toothed ring 13 extends into the annular groove 18. There are four clamping blocks 7 and four rotating grooves 11. Pressure pads are fixedly installed at the bottom of the pressure block 20 and the top of the support block 22. A support slide plate 25 is fixedly installed on the inner side of the connecting frame 19. A support slide groove 26 is opened on the outer wall of the movable plate 5. The support slide plate 25 and the support slide groove 26 are slidably connected.

[0030] By setting pressure pads, hard contact between the pressure block 20, the support block 22 and the lens can be avoided, reducing wear and providing a certain degree of protection for the lens.

[0031] Furthermore, a limiting ring plate 14 is fixedly installed at the bottom of the ring plate 27, and a limiting ring groove 15 is opened at the top of the movable plate 5. The limiting ring plate 14 and the limiting ring groove 15 are rotatably connected.

[0032] The limiting ring plate 14 and the limiting ring groove 15 can limit the ring plate 27, so that the ring plate 27 can be fixedly rotated on the moving plate 5.

[0033] Furthermore, a limiting slider 16 is fixedly installed on the outer wall of the threaded sleeve 9, and a limiting groove 17 is opened on the inner wall of the shrinkage groove 8, with the limiting slider 16 and the limiting groove 17 slidably connected.

[0034] By setting the limiting slider 16 and the limiting groove 17, the threaded sleeve 9 can be limited to ensure the normal expansion and contraction of the threaded sleeve 9.

[0035] Furthermore, an electric cylinder 4 is fixedly installed at the top of the top plate 3, and the piston rod of the electric cylinder 4 moves through the top plate 3. The movable plate 5 is fixedly installed at the bottom end of the piston rod of the electric cylinder 4.

[0036] Among them, by setting up an electric cylinder 4, the movable plate 5 of the electric cylinder 4 can be moved up or down.

[0037] Specifically, in the above technical solution, the lens to be processed is placed on the support block 22. When the edge of the lens needs to be processed, the electric cylinder 4 can be activated, causing the electric cylinder 4 to move the moving plate 5 downward. The moving plate 5, through the support slide plate 25, moves the connecting frame 19 downward, causing the connecting frame 19 to move the pressure block 20 downward. Finally, the pressure block 20 presses the top of the lens, and the edge of the lens can then be processed. When the surface of the lens needs to be processed, the fastening screw 23 can be rotated to disengage from the connecting block 24, so that the fastening screw 23 no longer limits the connecting frame 19. Then, the connecting frame 19 is pulled to one side, so that the connecting frame 19 and the pressure block 20 are not below the fixing port 6. Then, the electric cylinder 4 can be activated, causing the electric cylinder 4 to move the moving plate 5 downward, so that the fixing port 6 on the moving plate 5 presses against the support block 22. The lens on plate 2 is covered, and then the ring plate 27 can be rotated, causing the ring plate 27 to drive the gear ring 13 to rotate. The gear ring 13 drives the gear 12 to rotate, and the gear 12 drives the drive screw 10 to rotate. The drive screw 10 drives the threaded sleeve 9 to move out of the shrinkage groove 8. The threaded sleeve 9 drives the clamping block 7 to move towards the lens, and finally the four clamping blocks 7 press and fix the edge of the lens. At this time, the lens surface can be processed. Through the above structure, the pressing and fixing position of the lens can be quickly adjusted according to the processing needs, improving the processing efficiency. It solves the problem that the existing technical solution can only press and fix the lens from the top of the lens by pressing blocks, which means that only the edge of the lens can be processed. When the surface of the lens needs to be processed, another pressing and fixing device needs to be replaced, which has certain limitations and affects the processing efficiency of the lens.
