Description

Technical Field

[0001] This utility model relates to the field of concave lens processing technology, specifically a positioning mechanism for processing the surface of a concave lens. Background Technology

[0002] Concave lenses diverge light rays; parallel light rays passing through a concave lens are diverged, and the backward extensions of these diverging rays intersect at the lens's virtual focal point. The image formed by a concave lens is always an upright, reduced virtual image; it cannot form a real image. Concave lenses have wide applications in daily life, such as correcting myopia, and are also used in cat's eye design and in telescopes to correct image distortion and blur.

[0003] During the production process, concave lenses require surface processing, such as trimming the edges with scissors to make them rounded. Traditional positioning mechanisms have poor positioning effects and limited applicability, making it difficult to effectively position concave lenses and reducing the processing quality of concave lenses. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a positioning mechanism for processing concave lens surfaces. This mechanism has the advantages of effectively positioning concave lenses of different diameters and thicknesses, convenient adjustment, and high efficiency. It solves the problems of poor positioning effect, limited applicability, and difficulty in effectively positioning concave lenses in traditional positioning mechanisms.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism for processing the surface of a concave lens, comprising a base plate, threaded holes at each of the four corners of the base plate, a column fixedly connected to the top of the base plate, a concave lens disposed above the column, a frame fixedly connected to the surface of the column, a clamping mechanism disposed on one side of the concave lens, and an adjustment mechanism disposed below the clamping mechanism. The clamping mechanism is used to fix the concave lens above the column; The adjustment mechanism is used to adjust the height of the clamping mechanism, so that the clamping mechanism can adapt to concave lenses of different thicknesses.

Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth. Example

[0021] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a base plate 1, with threaded holes 2 at each of the four corners of the base plate 1. A column 3 is fixedly connected to the top of the base plate 1, a concave lens 4 is disposed above the column 3, a frame 5 is fixedly connected to the surface of the column 3, a clamping mechanism 6 is disposed on one side of the concave lens 4, and an adjustment mechanism 7 is disposed below the clamping mechanism 6. The clamping mechanism 6 is used to fix the concave lens 4 above the column 3; The adjustment mechanism 7 is used to adjust the height of the clamping mechanism 6, so that the clamping mechanism 6 can adapt to concave lenses 4 of different thicknesses.

[0022] Specifically, it achieves the effect of effectively positioning concave lenses 4 with different diameters and thicknesses, and is convenient and efficient to adjust.

[0023] Furthermore, the rotation of the bidirectional lead screw 601 drives the connecting rod 602 to move relative to or towards each other, causing the elastic clamp 603 to move closer to or further away from the concave lens 4, thus achieving clamping and releasing, adapting to concave lenses 4 of different diameters. In the adjustment mechanism 7, the rotation of the screw 704 drives the stop block 703 to fix or release the sliding block 702, and the sliding block 702 can slide along the column 3 to adjust the height of the clamping mechanism 6.

[0024] The top of the column 3 has a groove 8. The groove 8 provides a space for the concave lens 4, allowing the bottom of the concave lens 4 to be embedded in it, forming a preliminary positioning constraint. This enhances the stability of the concave lens 4.

[0025] A protective pad 9 is fixedly connected to the inner wall of the groove 8, and the protective pad 9 contacts the spherical surface of the concave lens 4. The protective pad 9 is soft and can conform to the surface of the concave lens 4 when in contact with it, preventing the concave lens 4 from making hard contact with the groove 8. The protective pad 9 can prevent the spherical surface of the concave lens 4 from being scratched. Example

[0026] The second embodiment of this utility model provides a clamping mechanism 6 including a bidirectional lead screw 601, a connecting rod 602 being connected to the surface of the bidirectional lead screw 601, and an elastic clamp 603 being fixedly connected to one side of the connecting rod 602.

[0027] Specifically, the elastic clip 603 can adapt to the surface size of the concave lens 4 and can also prevent hard contact from damaging the concave lens 4 to a certain extent. The clamping mechanism 6 can also adapt to concave lenses 4 of different diameters.

[0028] Furthermore, when the bidirectional lead screw 601 is rotated by the knob 12, it drives the connecting rod 602 of the surface transmission connection to move relative to or towards each other, thereby causing the elastic clamp 603 on one side of the connecting rod 602 to move closer to or further away from the concave lens 4, thus achieving the clamping and releasing of the concave lens 4. Example

[0029] The third embodiment of this utility model provides an adjustment mechanism 7 including a fixed block 701 rotatably connected to the surface of a bidirectional lead screw 601 via a bearing. A sliding block 702 is fixedly connected to the bottom of the fixed block 701. The sliding block 702 is slidably sleeved on the surface of the column 3. A stop block 703 is provided on the front side of the sliding block 702. The stop block 703 abuts against the sliding block 702. A screw 704 is rotatably connected to the front side of the stop block 703 via a bearing. A square block 705 is drively connected to the surface of the screw 704. The square block 705 is slidably connected to the inner wall of the frame 5 via a slider and a groove.

[0030] Specifically, the height is adjusted by rotating the screw 704, which is convenient to operate and allows the clamping mechanism 6 to work stably at different height positions, meeting the processing and positioning requirements of concave lenses 4 of different thicknesses.

[0031] Furthermore, by rotating the screw 704 via the knob 12, since the screw 704 is connected to the block 705 and the block 705 is slidably connected to the inner wall of the frame 5 via the slider and the groove, the rotation of the screw 704 will cause the abutment 703 to move toward the sliding block 702 with the cooperation of the block 705, thereby fixing the sliding block 702 on the column 3 by the abutment 703. When the knob 12 is reversed to release the sliding block 702 by the abutment 703, the sliding block 702 can slide up and down along the surface of the column 3 to adjust the height of the clamping mechanism 6.

[0032] A long plate 10 is fixedly connected to the right side of the fixing block 701. A square groove 11 is formed on the surface of the long plate 10. The right end of the connecting rod 602 extends to the right side of the long plate through the square groove 11, and the surface of the connecting rod 602 is slidably connected to the inner wall of the square groove 11. The connecting rod 602 slides in the square groove 11. The arrangement of the long plate 10 and the square groove 11 prevents the connecting rod 602 from shifting during movement, thereby improving the stability of the clamping mechanism 6.

[0033] As a preferred embodiment of this utility model, an additional force application point is provided for rotating the bidirectional lead screw 601 and the screw 704, making it convenient for operators to rotate the bidirectional lead screw 601 and the screw 704. The setting of the knob 12 makes the operation more labor-saving and convenient.

[0034] The base plate 1 is fixed to the working area through the threaded hole 2. Then, the concave lens 4 is placed on the protective pad 9 in the groove 8. Subsequently, the screw 704 is rotated by the knob 12. Since the screw 704 is connected to the block 705 and the block 705 is slidably connected to the inner wall of the frame 5 through the slider and the slide groove, the rotation of the screw 704 will drive the abutment 703 to move towards the sliding block 702 with the cooperation of the block 705. This will cause the abutment 703 to fix the sliding block 702 on the column 3. When the knob 12 is reversed to release the sliding block 702, the sliding block 702 can slide up and down along the surface of the column 3 to adjust the height of the clamping mechanism 6. The height adjustment is achieved by rotating the screw 704. The operation is convenient and the clamping mechanism 6 can work stably at different height positions to meet the processing and positioning needs of concave lenses 4 of different thicknesses. The mechanism 6 utilizes the knob 12 to rotate the bidirectional lead screw 601, causing the connecting rod 602, which is connected to the surface drive, to move relative to or towards each other. This allows the elastic clamp 603 on one side of the connecting rod 602 to move closer to or further away from the concave lens 4, thus clamping and releasing the concave lens 4. The elastic clamp 603 can adapt to the surface size of the concave lens 4 and can also prevent damage to the concave lens 4 from hard contact to a certain extent. The clamping mechanism 6 can also adapt to concave lenses 4 of different diameters. The connecting rod 602 slides in the square groove 11. The long plate 10 and the square groove 11 prevent the connecting rod 602 from shifting during movement, thus improving the working stability of the clamping mechanism 6. The knob 12 provides an additional force point for rotating the bidirectional lead screw 601 and the screw 704, making it convenient for the operator to rotate the bidirectional lead screw 601 and the screw 704.

[0035] In summary, the combination of the clamping mechanism and the adjustment mechanism enables effective positioning of concave lenses of different diameters and thicknesses, and provides convenient and efficient adjustment.
