Technical Field
[0001] This utility model relates to the field of fixture technology, and in particular to a special fixture for polishing high-precision optical lenses. Background Technology
[0002] High-precision optical lens polishing fixtures are precision tooling equipment designed specifically for optical lens polishing processes. They aim to ensure accurate positioning, stable fixation, and efficient polishing of lenses during the polishing process.
[0003] In actual use, existing fixtures often experience wear and tear on the gears outside the fixture over time, leading to insufficient meshing between the gears and the machine. This results in the fixture not rotating precisely along the designated path, which in turn affects the lens polishing effect. Therefore, a special fixture for high-precision optical lens polishing is needed to quickly replace the worn-out gears, thereby reducing the cost of using fixtures and maintaining the polishing effect on the lenses. Utility Model Content
[0004] The purpose of this utility model is to provide a special fixture for high-precision optical lens polishing, in order to solve the problem mentioned in the background art that, in actual use, the gears on the outside of the fixture are prone to insufficient meshing with the machine due to long-term wear, which causes the fixture to not rotate accurately along the predetermined path, thus affecting the lens polishing effect.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a special fixture for high-precision optical lens polishing, comprising:
[0007] A clamping assembly, the clamping assembly including a clamping body and gears that fit against the outer surface of the clamping body;
[0008] The mounting assembly is located inside the clamping assembly. The mounting assembly includes a mounting groove, a fixed plate, a movable plate, and a limiting post. The mounting groove is opened inside the clamping body and the gear. The fixed plate is located inside the mounting groove and is fixed inside the clamping body. The movable plate is slidably connected to the inside of the fixed plate. The limiting post is fixed to the outer surface of the movable plate and is locked inside the gear.
[0009] Furthermore, the fixed plate has a movable groove inside, and the movable plate is located inside the movable groove.
[0010] Furthermore, a guide post is fixed to the upper surface of the movable plate, and a connection hole is opened inside the guide post.
[0011] Furthermore, it also includes a protective component located inside the mounting slot (21). The protective component includes a protective plate, a limiting rod, and a movable slot. The protective plate is inserted into the mounting slot, the limiting rod is fixed to the lower surface of the protective plate, the limiting rod is inserted into the movable slot, and the movable slot is opened inside the protective plate.
[0012] Furthermore, the protective plate has a guide hole inside, and the protective plate and the fixing plate are threadedly connected to a threaded rod inside.
[0013] Furthermore, a connecting plate is fixed to the upper surface of the threaded rod, and a guide groove is formed inside the connecting plate.
[0014] Compared with existing technologies, the advantages of this utility model are:
[0015] I. This utility model, through its installation components, allows for the replacement of over-worn gears when the gears are excessively worn. A tool is inserted into the connecting hole, applying a pushing force to the guide post, causing the movable plate to move within the movable groove. This causes the limiting post to retract into the fixed plate, where a downward pressing force is applied to the gear, removing the worn gear from the outside of the fixture body. A new gear is then fitted onto the outside of the fixture body. Using this method, the limiting post can be inserted into the gear. This solution allows for the rapid replacement of over-worn gears, reducing the cost of using fixtures while maintaining the polishing effect on the lens.
[0016] II. Based on the first beneficial effect, when the protective plate needs to be fixed inside the mounting slot with the cooperation of the protective components, first insert the tool into the guide hole, put the protective plate into the mounting slot, so that the limiting rod is inserted into the movable slot, then insert the threaded rod into the protective plate, place the tweezers inside the guide slot, and apply a rotational force to the connecting plate so that the threaded rod is turned into the protective plate and the fixed plate. This solution can not only stably fix the limiting post in the required position, but also prevent external impurities from entering the mounting slot and affecting the normal use of the parts inside the mounting slot.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0030] Please see Figures 1-5 As shown, this embodiment is a special fixture for high-precision optical lens polishing, comprising:
[0031] The clamping assembly includes a clamping body 11 and a gear 12 that fits against the outer surface of the clamping body 11.
[0032] The fixture body 11 serves as the basic structure of the entire fixture, providing a platform for placing and positioning the lens. The gear 12 is used to connect with the equipment. When the lens needs to be polished, the lens is first placed inside the fixture body 11, and then the fixture body 11 is placed in a vacuum environment for evaporation coating and polishing.
[0033] The mounting assembly, located inside the clamping assembly, includes a mounting groove 21, a fixed plate 22, a movable plate 24, and a limiting post 25. The mounting groove 21 is formed inside the clamping body 11 and the gear 12. The fixed plate 22 is located inside the mounting groove 21 and is fixed inside the clamping body 11. The movable plate 24 is slidably connected to the inside of the fixed plate 22. The limiting post 25 is fixed to the outer surface of the movable plate 24 and is engaged inside the gear 12.
[0034] The mounting slot 21 is used to receive and install the fixing plate 22. The fixing plate 22 provides a fixed base for the limiting post 25. The movable plate 24 is used to change the position of the limiting post 25. The limiting post 25 is used to lock into the inside of the gear 12, thereby connecting the clamp body 11 and the gear 12 together.
[0035] The fixed plate 22 has a movable groove 23 inside, and the movable plate 24 is located inside the movable groove 23;
[0036] The movable groove 23 provides sliding space for the movable plate 24, ensuring that the movable plate 24 moves smoothly inside the fixed plate 22;
[0037] A guide post 26 is fixed on the upper surface of the movable plate 24, and a connecting hole 27 is provided inside the guide post 26;
[0038] The guide post 26 facilitates the application of a pushing force to the movable plate 24, and the connecting hole 27 allows external tools to be inserted to push the movable plate 24 to move.
[0039] Working principle: When gear 12 is worn excessively, insert the tool into the connecting hole 27 and apply a pushing force to the guide post 26, causing the movable plate 24 to move inside the movable groove 23. After the limiting post 25 retracts into the fixed plate 22, apply a downward pressing force to the gear 12 to remove the worn gear 12 from the outside of the clamp body 11. Then, put the new gear 12 on the outside of the clamp body 11. Using the above method, the limiting post 25 can be inserted into the gear 12.
[0040] This step allows for the quick replacement of over-broken-in gear 12, reducing the cost of using fixtures while maintaining the polishing effect on the lens.
[0041] Please see Figures 1-4 As shown, this embodiment is based on the above embodiment and also includes a protective component. The protective component is located inside the mounting groove 21 and includes a protective plate 31, a limiting rod 32 and a moving groove 33. The protective plate 31 is stuck inside the mounting groove 21, the limiting rod 32 is fixed to the lower surface of the protective plate 31 and inserted into the moving groove 23, and the moving groove 33 is opened inside the protective plate 31.
[0042] The protective plate 31 is inserted into the mounting groove 21, covering and protecting the other components inside the mounting groove 21. The limiting rod 32 is used to limit the movable plate 24 to the desired position, thereby stably fixing the limiting post 25 to the desired position. The movable groove 33 facilitates the insertion of tools into the guide hole 34.
[0043] The protective plate 31 has a guide hole 34 inside, and the protective plate 31 and the fixing plate 22 are threadedly connected to a threaded rod 35.
[0044] The guide hole 34 is used to connect with the tool, so as to facilitate the movement of the protective plate 31 to the desired position, and the threaded rod 35 is used to fix the protective plate 31 inside the mounting groove 21;
[0045] A connecting plate 36 is fixed to the upper surface of the threaded rod 35, and a guide groove 37 is provided inside the connecting plate 36.
[0046] The connecting plate 36 provides an interface for rotating the threaded rod 35, and with the setting of the guide groove 37, it is convenient to apply rotational force to the connecting plate 36. The guide groove 37 is used for tool insertion, thereby facilitating the application of force to the connecting plate 36.
[0047] Working principle: When it is necessary to fix the protective plate 31 inside the mounting slot 21, first insert the tool into the guide hole 34, put the protective plate 31 into the mounting slot 21, so that the limiting rod 32 is inserted into the movable slot 23, then insert the threaded rod 35 into the protective plate 31, place the tweezers inside the guide slot 37, and apply a rotational force to the connecting plate 36 so that the threaded rod 35 rotates into the protective plate 31 and the fixing plate 22.
[0048] This step not only stably fixes the limiting post 25 in the required position, but also prevents external impurities from entering the mounting groove 21 and affecting the normal use of the parts inside the mounting groove 21.
