Description

Technical Field

[0001] This utility model relates to the field of optical glass polishing technology, specifically a surface polishing device for irregularly shaped optical elements of zoom lenses. Background Technology

[0002] Optical glass refers to glass that can change the direction of light propagation and alter the relative spectral distribution of ultraviolet, visible, or infrared light. Optical glass can be used to manufacture lenses, prisms, mirrors, and windows in optical instruments. During the production process of optical glass, it is necessary to polish the glass to make it smooth.

[0003] Upon investigation, a Chinese utility model patent discloses an optical component polishing device (publication number: CN214923057U), which includes a base. A first support plate and a second support plate are fixedly connected to the upper side of the base. The first support plate and the second support plate are arranged in parallel. A horizontal plate is fixedly connected to the upper ends of the first support plate and the second support plate. A spray head is fixedly connected to the bottom of the horizontal plate. The first support plate is provided with a clamping device, and the second support plate is provided with a polishing device.

[0004] Although the aforementioned patent uses a first cylinder to push the push ring to move, and the push ring simultaneously squeezes multiple rotating rods to rotate, with the number of rotating rods set according to the edge of the workpiece to be ground, the push ring squeezes the rotating rods to rotate to the corresponding angle, thus facilitating the clamping of edge surfaces with different slopes, this device can only clamp edge surfaces. If it encounters irregularly shaped optical glass, the rotating rods on this device cannot clamp it securely. Therefore, it is particularly important to set up a device that can securely clamp irregularly shaped optical glass.

[0005] Therefore, this utility model provides a surface polishing device for irregularly shaped optical elements of zoom lenses to solve the above-mentioned problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a surface polishing device for irregularly shaped optical elements of zoom lenses, such as... Figures 1-6 As shown, the technical solution includes a base 1 and a grinding device 2. A support rod 3 is fixedly connected to the base 1, and a connecting rod 4 is slidably connected to the support rod 3. A placement platform 6 is fixedly connected to the top of the connecting rod 4. Mounting plates 8 are symmetrically arranged on both sides of the placement platform 6. Each mounting plate 8 is equipped with a shaped clamping mechanism. The shaped clamping mechanism includes multiple positioning posts 9, sliding rods 15, and springs 16. The springs 16 are sleeved on the sliding rods 15. The shaped clamping mechanism clamps the shaped optical glass. The springs 16 in the shaped clamping mechanism push the positioning posts 9 to abut against the side wall of the shaped optical glass, so that the multiple positioning posts 9 clamp the side wall of the shaped optical glass. A sliding groove is opened on the mounting plate 8, and a connecting plate 18 is slidably connected in the sliding groove. Multiple pressing blocks 19 are fixedly connected to the connecting plate 18. The multiple pressing blocks 19 press and limit the multiple sliding rods 15 in the shaped clamping mechanism, thereby limiting and fixing the positioning posts 9 and improving the stability of the shaped clamping mechanism in clamping the shaped optical glass.

[0027] The side wall of the support rod 3 is threaded with a positioning bolt 5. The end of the positioning bolt 5 abuts against the connecting rod 4. When in use, the positioning bolt 5 is rotated to separate the positioning bolt 5 from the connecting rod 4. At this time, the connecting rod 4 can be moved to adjust the height of the placement platform 6. After the height of the placement platform 6 is adjusted, the positioning bolt 5 is rotated again to abut against the connecting rod 4, which can limit the connection rod 4, thereby achieving the effect of adjusting the height of the placement platform 6.

[0028] The base 1 has an installation groove, in which a bidirectional lead screw 12 is rotatably connected. Two sliders 13 are slidably connected in the installation groove, and the sliders 13 are threadedly connected to the bidirectional lead screw 12. A support plate 7 is fixedly connected to the top of the sliders 13, and the top of the support plate 7 is fixedly connected to the installation plate 8. A handle 11 is rotatably connected to the side wall of the base 1, and the handle 11 is coaxially fixed to the bidirectional lead screw 12.

[0029] When in use, rotating the handle 11 drives the bidirectional lead screw 12 to rotate. The rotating bidirectional lead screw 12 drives the two sliders 13 to move in opposite directions. The sliders 13 drive the mounting plate 8 to move through the support plate 7, thereby driving the irregular clamping mechanism set on the mounting plate 8 to move, so that the irregular clamping mechanism clamps and fixes the irregular clamping glass on the placement platform 6.

[0030] The mounting plate 8 has multiple cavities. The positioning post 9 slides through one side of the cavity, and the slide rod 15 slides through the other side of the cavity. A baffle 14 is fixedly connected inside the cavity. The baffle 14 is fixedly connected between the positioning post 9 and the slide rod 15. The two ends of the spring 16 are fixedly connected to the baffle 14 and the inner wall of the cavity, respectively. A screw 10 is rotatably connected to the top of the mounting plate 8. The screw 10 passes through the connecting plate 18 and is threadedly connected to the connecting plate 18. A round rod 17 is fixedly connected to the top of the mounting plate 8, and the round rod 17 slides through the top of the connecting plate 18.

[0031] During use, the mounting plate 8 moves the irregular clamping mechanism toward the irregular optical glass. The side wall of the irregular optical glass presses against the positioning post 9. The positioning post 9 drives the baffle 14 to compress the spring 16. With the reset action of the spring 16, the positioning post 9 is always pressed against the side wall of the irregular optical glass. Then, the screw 10 is rotated to move the connecting plate 18. The connecting plate 18 drives the pressing block 19 to press and limit the slide rod 15, improving the stability of the positioning post 9 and preventing the positioning post 9 from loosening due to insufficient elasticity of the spring 16.

[0032] In summary: During operation, rotating the handle 11 drives the bidirectional lead screw 12 to rotate. The rotating bidirectional lead screw 12 drives the two sliders 13 to move in opposite directions. The sliders 13 drive the mounting plate 8 to move through the support plate 7, thereby driving the irregular clamping mechanism set on the mounting plate 8 to move, so that the irregular clamping mechanism clamps and fixes the irregular clamping glass on the placement table 6.

[0033] During the clamping process, the side wall of the irregularly shaped optical glass presses against the positioning post 9, and the positioning post 9 drives the baffle 14 to compress the spring 16. With the reset action of the spring 16, the positioning post 9 is pushed to always abut against the side wall of the irregularly shaped optical glass. Then, the screw 10 is rotated to drive the connecting plate 18 to move. The connecting plate 18 drives the pressing block 19 to press and limit the slide rod 15, thereby improving the stability of the positioning post 9.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
