Description

Technical Field

[0001] This utility model relates to the field of optical glass processing technology, and more specifically, to an optical glass core-fixing and precise positioning device. Background Technology

[0002] Optical glass offers exceptional transparency and superior optical performance, ensuring that devices can accurately sense, transmit, and record light. It is widely used in various optical devices, such as telescopes, microscopes, cameras, and mobile phones.

[0003] After searching, it was found that application number CN202421036019.7, entitled "A Precision Positioning and Drilling Device for Optical Glass," addresses the issue that during the processing of optical glass, some parts require drilling. Typically, the glass is placed on a table, positioned by a clamp, and then drilled using a drilling device. However, due to the lack of a structure for rapid centering and positioning of optical glass, mass production requires multiple loading and unloading operations on the clamping device, leading to inaccurate positioning and difficulty in achieving rapid and precise drilling while loading and unloading. This application addresses the problem by using two mirror-distributed first clamping plates and... The second clamping plate completes the positioning and clamping. However, this application uses two sets of motors to drive the first and second clamping plates to move respectively. The two sets of motors are difficult to work synchronously. Once a delay occurs, it means that one set of clamping plates cannot be in place in time, affecting the accuracy of clamping and positioning. In other words, the first and second clamping plates are difficult to operate synchronously, affecting work efficiency. At the same time, the two sets of motors in this application can only position and clamp one set of optical lenses. When it is necessary to position and clamp multiple sets of optical lenses at the same time, multiple sets of motors are required, resulting in a complex structure, high production costs, and work efficiency that can be further improved.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a precise positioning device for optical glass core fixing, which has the following beneficial effects:

[0019] (1) This utility model adopts a rotating shaft, a top plate, a thin steel cable and a positioning clamp. When accurately positioning the optical glass core, the optical glass can be placed between the positioning clamps. Then, the drive motor is started, which drives the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the rotating shaft and the top plate to rotate. The top plate rotates while winding the thin steel cable. The thin steel cable can simultaneously pull the positioning clamp to close and clamp the optical glass. Since the positioning clamps are distributed at equal angles and equal intervals along the vertical central axis of the rotating shaft and move inward at the same time, the position of the optical glass can be corrected during the clamping process to complete the core positioning. The positioning clamps work synchronously, making the positioning more accurate and reliable and the work efficiency higher. At the same time, the thin steel cable is used to pull the positioning clamp to clamp the optical glass, making the structure simpler and the use more convenient.

The synchronous core positioning of multiple sets of optical glass can be completed by a single drive motor, which significantly improves the working efficiency and further simplifies the structure.

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, an optical glass core-fixing precision positioning device is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, an optical glass core-setting precision positioning device according to an embodiment of the present invention includes a positioning box 1 and a base box 2. The top surface of the positioning box 1 has a top groove 8, and a positioning clamping plate 10 is connected through the top groove 8. The width of the positioning clamping plate 10 is the same as the width of the top groove 8. A guide rod 11 is fixedly connected inside the top groove 8, and the guide rod 11 passes through the positioning clamping plate 10. A rotating shaft 6 is rotatably connected inside the base box 2 via a rotating connecting seat 5. The rotating shaft 6 passes through the bottom surface of the positioning box 1 and extends between the positioning clamping plates 10. A top plate 9 is fixedly installed on the top surface of the rotating shaft 6. The top plate 9 is connected to one side of the bottom surface of the positioning clamping plate 10 via a thin steel cable 13. The thin steel cable 13 is not easily stretched or deformed, ensuring stability. A drive motor 3 is fixedly installed at one end of the base box 2, and a worm gear 4 is installed at the output end of the drive motor 3. A worm wheel 7 is fixedly sleeved on the surface of the rotating shaft 6. The worm gear 7 meshes with the worm 4, which is a common drive structure. When precisely positioning the optical glass for core fixing, the optical glass can be placed between the positioning clamps 10. Then, the drive motor 3 is started, which drives the worm 4 to rotate, which in turn drives the worm gear 7 to rotate, which in turn drives the rotating shaft 6 and the top plate 9 to rotate. As the top plate 9 rotates, the thin steel cable 13 is wound up. The thin steel cable 13 can simultaneously pull the positioning clamps 10 to close and clamp the optical glass. Since the positioning clamps 10 are distributed at equal angles and intervals along the vertical central axis of the rotating shaft 6 and move inward at the same time, the position of the optical glass can be corrected during the clamping process, thus completing the core fixing and positioning. The positioning clamps 10 work synchronously, making the positioning more accurate and reliable, and the work efficiency higher. At the same time, the thin steel cable 13 pulls the positioning clamps 10 to clamp the optical glass, making the structure simpler and more convenient to use.

[0031] In one embodiment, multiple sets of positioning clamps 10 are arranged at equal angles and intervals along the vertical central axis of the rotation shaft 6, and the surface of the positioning clamps 10 is roughened. When the drive motor 3 drives the worm 4 to rotate, it drives multiple worm wheels 7 and the rotation shaft 6 to rotate, thereby driving multiple sets of positioning clamps 10 to work synchronously. The synchronous core positioning of multiple sets of optical glass can be completed by a single drive motor 3, which significantly improves the working efficiency and further simplifies the structure.

[0032] In one embodiment, the guide rod 11 is slidably connected to the positioning clamping plate 10, and a spring 12 is sleeved on the outer side of the guide rod 11 at one end of the positioning clamping plate 10 and the top groove 8. The two ends of the spring 12 are fixedly connected to the surface of the positioning clamping plate 10 and the inner wall of the top groove 8, respectively. When the positioning clamping plate 10 closes and clamps, the spring 12 is compressed, which facilitates the drive motor 3 to drive the worm gear 4 to rotate in the opposite direction and push the positioning clamping plate 10 to reset.

[0033] In one embodiment, the two ends of the thin steel cable 13 are fixedly connected to the positioning clamp 10 and the top plate 9, respectively, and the thin steel cable 13 has the same length to avoid deviation in the distribution of the positioning clamp 10 due to the different lengths of the thin steel cable 13.

[0034] In one embodiment, the worm gear 4 passes through both ends of the base box 2 and is rotatably connected to both ends of the base box 2 via bearings, thereby stabilizing the rotation of the worm gear 4.

[0035] In one embodiment, the rotating shaft 6 is rotatably connected to the positioning box 1 via a bearing to stabilize the rotation of the rotating shaft 6.

[0036] In one embodiment, the rotating shaft 6, top plate 9, worm gear 7, and rotating connecting seat 5 are arranged coaxially to improve rotational stability.

[0037] Working principle:

[0038] When precisely positioning the optical glass for core fixing, the optical glass can be placed between the positioning clamps 10. Then, the drive motor 3 is started, which drives the worm gear 4 to rotate, which in turn drives the worm wheel 7 to rotate, which in turn drives the rotating shaft 6 and the top plate 9 to rotate. As the top plate 9 rotates, it simultaneously winds up the thin steel cable 13, which in turn pulls the positioning clamps 10 to close and clamp the optical glass. Since the positioning clamps 10 are evenly distributed at equal angles and intervals along the vertical central axis of the rotating shaft 6, and simultaneously move inward, the position of the optical glass can be corrected during the clamping process, thus completing the core fixing. Positioning clamps 10 work synchronously, making positioning more accurate and reliable, and improving work efficiency. At the same time, the positioning clamps 10 are pulled by thin steel cables 13 to clamp the optical glass, making the structure simpler and easier to use. In addition, multiple sets of positioning clamps 10 are arranged. When the drive motor 3 drives the worm gear 4 to rotate, it drives multiple worm wheels 7 and rotating shaft 6 to rotate, which can drive multiple sets of positioning clamps 10 to work synchronously. The synchronous core positioning of multiple sets of optical glass can be completed by a single drive motor 3, which significantly improves work efficiency and further simplifies the structure.
