Description

Technical Field

[0001] This application relates to the field of lens processing technology, and more specifically, to an optical lens surface polishing apparatus. Background Technology

[0002] Optical lenses are made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula. This mixture is melted at high temperature in a platinum crucible and ultrasonically stirred to remove air bubbles. Then, it undergoes a long, slow cooling process to prevent internal stress in the lens block. After cooling, the lens block must be measured with optical instruments to check its purity, transparency, uniformity, refractive index, and dispersion to ensure they meet specifications. Qualified lens blocks are then heated and forged to form optical lens blanks. Lens polishing machines are used in the lens production process.

[0003] A search revealed that the publication (announcement) number CN216138651U discloses "an optical lens polishing device, including a housing, a support plate disposed in the middle position inside the housing, and a support seat disposed in the middle position at the top of the support plate... The beneficial effects are: it can polish optical lenses, and can clamp and fix the lenses on the side during polishing to avoid affecting the polishing operation, and can also filter and recycle the polishing liquid." However, this application requires rotating two adjusting bolts separately to clamp and fix the lens with the two clamping plates when fixing the lens. In actual use, the operation is complicated and troublesome, and it takes a lot of time.

[0004] To address the aforementioned problems, this application provides an optical lens surface polishing apparatus. Utility Model Content

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This application discloses an optical lens surface polishing device, including a worktable 1. A polishing assembly is provided on the top of the worktable 1. A groove 15 is formed on the bottom end face of the worktable 1. Two rotating shafts 16 are symmetrically rotatably connected to the inner top wall of the groove 15. Gears 17 are fixedly connected to the outer side of the rotating shafts 16. A rack plate 11 is slidably connected inside the groove 15. A first electric push rod 2 is fixedly connected to the outer side of the worktable 1. The output end of the first electric push rod 2 extends into the interior of the groove 15 and is fixedly connected to the rack plate 11. Two clamping plates are symmetrically slidably connected to the top of the worktable 1. 9. A limiting groove 22 is provided on the bottom end face of the clamping plate 9. Two incomplete annular holes 19 connected to the groove 15 are symmetrically provided on the top of the worktable 1. A limiting post 18 is fixedly connected to the top of the gear 17. The top end of the limiting post 18 passes through the incomplete annular hole 19 and is inserted into the limiting groove 22. The polishing assembly includes a support rod 4 fixedly connected to the top of the worktable 1. The operation of the first electric push rod 2 is controlled to drive the rack plate 11 to move. The rack plate 11 slides on the outside of the limiting plate 12 through the slide groove. The movement of the rack plate 11 drives the two gears 17 to rotate in opposite directions. When gear 17 rotates, it drives the rotating shaft 16 to rotate. The top of the rotating shaft 16 rotates inside the circular groove through the action of the annular slider and the annular groove. The rotation of gear 17 drives the limiting post 18 to rotate. The rotation of the limiting post 18, in conjunction with the limiting groove 22 opened on the bottom end face of the clamping plate 9 slidably connected to the top of the worktable 1, allows the clamping plate 9 to move. Controlling the first electric push rod 2 to drive the rack plate 11 to move forward can cause the two gears 17 to rotate in opposite directions, thereby causing the two limiting posts 18 to rotate in opposite directions. The rotation of the two limiting posts 18 in opposite directions causes the two gears 17 to rotate in opposite directions. The clamping plate 9 moves relative to the optical lens to clamp and fix it. The top plate 5 is fixedly connected to the top of the support rod 4. The top of the top plate 5 is fixedly connected to the second electric push rod 6. The output end of the second electric push rod 6 passes through the middle of the top plate 5 and is fixedly connected to the motor 8. The output end of the motor 8 is fixedly connected to the polishing plate 7. Controlling the second electric push rod 6 can adjust the height of the polishing plate 7. Controlling the second electric push rod 6 can drive the motor 8 and the polishing plate 7 to move downward, so that the polishing plate 7 contacts the top of the optical lens. Then, controlling the motor 8 can drive the polishing plate 7 to rotate to polish the optical lens.

[0020] Please see Figure 2 , Figure 3 and Figure 4Both gears 17 are meshed and connected to the rack plate 11. The inner wall of the groove 15 is symmetrically fixedly connected to the limiting plate 12. The outer side of the rack plate 11 is symmetrically provided with sliding grooves that are adapted to the limiting plate 12. The rack plate 11 is slidably connected to the outer side of the limiting plate 12 through the two sliding grooves. There are four limiting plates 12 in total. The four limiting plates 12, together with the two sliding grooves, limit and slide the rack plate 11 inside the groove 15. When the electric push rod 2 works to drive the rack plate 11 to move, the rack plate 11 slides on the outer side of the limiting plate 12 through the sliding grooves.

[0021] Please see Figure 5 The inner top wall of the groove 15 is provided with a circular groove. The top end of the rotating shaft 16 is rotatably connected to the inside of the circular groove. The inner wall of the circular groove is provided with an annular sliding groove. A matching annular slider is rotatably connected inside the annular sliding groove. The annular slider is fixedly connected to the outer wall of the rotating shaft 16. The rotating shaft 16 is rotatably connected inside the circular groove through the cooperation of the annular slider and the annular sliding groove. When the rotating shaft 16 rotates, the rotating shaft 16 drives the annular slider to rotate inside the annular sliding groove.

[0022] Please see Figure 5 The top of the workbench 1 is symmetrically provided with sliding grooves 20. Sliding blocks 21 are slidably connected inside the sliding grooves 20. The bottom end face of the clamping plate 9 is fixedly connected to the top end face of the sliding block 21. The sliding block 21 is set in a "convex" shape. The sliding grooves 20, together with the sliding blocks 21, guide the clamping plate 9 to slide. When the limiting post 18 rotates and drives the clamping plate 9 to move, the clamping plate 9 slides inside the sliding grooves 20 through the sliding blocks 21, which improves the stability of the clamping plate 9 when sliding.

[0023] Please see Figure 2 and Figure 3 A cover plate 10 is provided on the lower side of the inside of the groove 15. Two positioning blocks 13 are symmetrically fixedly connected to the inner wall of the groove 15. Positioning grooves 14 that are adapted to the positioning blocks 13 are symmetrically opened on the cover plate 10. The cover plate 10 and the positioning blocks 13 are connected by fixing bolts 3. The cover plate 10 has symmetrically opened round holes, and the fixing bolts 3 are inserted into the round holes. The surface of the positioning blocks 13 has threaded grooves, and the fixing bolts 3 are threaded into the threaded grooves. By unscrewing the fixing bolts 3 from the threaded grooves, the fixing of the cover plate 10 is released, and the cover plate 10 can be removed from the inside of the groove 15, which facilitates the maintenance of the internal components of the groove 15.

[0024] The implementation principle of this application embodiment is as follows: the first electric push rod 2 is controlled to drive the rack plate 11 to move. The rack plate 11 slides on the outside of the limiting plate 12 through the slide groove. The movement of the rack plate 11 drives two gears 17 to rotate in opposite directions. When the gears 17 rotate, they drive the rotating shaft 16 to rotate. The top end of the rotating shaft 16 rotates inside the circular groove through the action of the annular slider and the annular slide groove. The rotation of the gears 17 drives the limiting post 18 to rotate inside the incomplete annular hole 19. The rotation of the limiting post 18, in conjunction with the limiting groove 22 opened on the bottom end face of the clamping plate 9 slidably connected to the top of the worktable 1, allows the clamping plate 9 to move linearly. The optical lens is placed at the top center of the worktable 1. The first electric push rod 2 is controlled to drive the rack plate 11 to move forward, which causes the two gears 17 to rotate in opposite directions, thereby causing the two limiting posts 18 to rotate in opposite directions. The rotation of the two limiting posts 18 in opposite directions causes the two clamping plates 9 to move relative to each other and clamp and fix the optical lens. Then, the second electric push rod 6 is controlled to drive the motor 8 and the polishing plate 7 to move downward, so that the polishing plate 7 contacts the top of the optical lens. Then, the motor 8 is controlled to drive the polishing plate 7 to rotate and polish the optical lens.
