Description

Technical Field

[0001] This utility model relates to the field of optical component assembly technology, specifically to a lens frame for mounting and adjusting optical lenses. Background Technology

[0002] In the fields of optical component processing, testing, and assembly, precise clamping and positioning of lenses are often required to meet the operational needs of different processes. Currently, existing lens clamping and adjustment devices suffer from several technical challenges: First, the clamping structure design is unreasonable. Some devices use rigid clamping methods, which can easily lead to scratches or breakage of the lens surface due to improper clamping force control. Elastic clamping structures often suffer from insufficient clamping stability, causing the lens to easily shift or even fall off during adjustment. Second, the positioning adjustment mechanism has limited precision. Traditional drive methods struggle to achieve smooth vertical lifting and precise positioning of the lens, and some devices lack effective limiting structures, making it easy for parts to detach during adjustment, affecting operational safety. Third, the overall support structure lacks stability. The connection strength between the base and the bracket is insufficient, easily causing wobbling when clamping heavy lenses or performing high-frequency adjustments, further reducing the device's operational reliability. These problems not only affect the efficiency and accuracy of lens processing and testing but may also cause lens damage and increase production costs.

[0018] 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.

[0019] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Example 1

[0021] Please see Figure 1-3 An embodiment of this utility model includes a base 1 and a hollow bracket 2. The base 1 and the hollow bracket 2 are in a vertical relationship, and the hollow bracket 2 is fixedly installed on the base 1. A clamping component for clamping a lens is slidably provided on the hollow bracket 2. A driving component for driving the clamping component to change position in the vertical direction is fixedly provided on the hollow bracket 2. The driving component is connected to the clamping component in a transmission manner.

[0022] The hollow bracket 2 is a hollow type bracket. The base 1 is vertically fixed to the hollow bracket 2 to provide stable support. In the initial state, the clamping component is in the initial vertical position on the hollow bracket 2 and clamps the lens. When it is necessary to adjust the vertical position of the lens, the drive component fixed on the hollow bracket 2 is activated. Through the transmission connection, the clamping component is driven to slide along the vertical direction of the hollow bracket 2 to realize the raising or lowering of the lens position. After the lens reaches the target position, the drive component stops working, and the clamping component maintains the current position on the hollow bracket 2. Throughout the process, the hollow design of the hollow bracket 2 does not affect the sliding of the clamping component and the clamping operation of the lens.

[0023] The clamping assembly includes a sliding seat 3 that is slidably connected to the hollow bracket 2. The sliding seat 3 has a sliding groove, and a guide rod 702 is fixedly installed in the sliding groove. Sliding clamping blocks 701 are symmetrically slidably installed on the outer periphery of the guide rod 702. Each sliding clamping block 701 has a clamping claw 707 fixedly installed on one end away from the sliding seat 3. Linkage rods 704 are also symmetrically slidably installed on the outer periphery of the guide rod 702. The two linkage rods 704 are located between the two sliding clamping blocks 701, and the opposite ends of the two linkage rods 704 are respectively fixedly connected to the near ends of the two sliding clamping blocks 701.

[0024] A hinged connecting rod 705 is hinged to one end of the linkage rod 704 away from the sliding seat 3. The clamping assembly also includes an arc-shaped clamping piece 706. The ends of the two hinged connecting rods 705 away from the linkage rod 704 are both hinged to one side of the arc-shaped clamping piece 706. Under normal conditions, the arc-shaped clamping piece 706 and the two clamping claws 707 form a circular surround.

[0025] A return spring 703 is also provided between the two sliding clamps 701 and the inner wall of the sliding seat 3. The return spring 703 is sleeved on the outer periphery of the guide rod 702.

[0026] Furthermore, the inner walls of the arc-shaped clamping piece 706 and the two clamping claws 707 are provided with fixing grooves, and the fixing grooves are provided with soft parts, including but not limited to silicone pads.

[0027] Specifically, when the clamping assembly is in its initial state, the return spring 703 (such as a spring) is in a naturally extended state. Its two ends exert outward pushing force on the inner wall of the sliding seat 3 and the two sliding clamps 701, causing the two sliding clamps 701 to slide smoothly along the outer periphery of the guide rod 702 in a direction away from each other. Since the sliding clamps 701 are fixedly connected to the linkage rod 704, the linkage rod 704 moves synchronously to both sides with the sliding clamps 701, thereby driving the hinged connecting rod 705 hinged to the end of the linkage rod 704 to rotate outward, so that the arc-shaped clamp 706 hinged to the other end of the hinged connecting rod 705 is in the outermost position. Finally, the arc-shaped clamp 706 and the two clamping claws 707 together form a circular enclosure with a fixed diameter. At this time, the silicone pads in the fixing grooves on the inner walls of the arc-shaped clamp 706 and the clamping claws 707 remain in a naturally extended state.

[0028] When a lens needs to be clamped, the lens is aligned with the surrounding ring and inserted, initially contacting the silicone pad and generating pressure. This pressure forces the curved clamping piece 706 to move closer to the sliding seat 3, while the two clamping claws 707 are squeezed and deflected inwards. This, in turn, causes the sliding clamping block 701, which is fixed to it, to overcome the elastic force of the return spring 703 and slide closer to each other along the outer circumference of the guide rod 702. As the sliding clamping block 701 slides, the linkage rod 704 retracts inwards simultaneously, causing the hinged connecting rod 705 to rotate inwards to accommodate the change in the relative position of the linkage rod 704 and the curved clamping piece 706. During this process, the return spring 703 is gradually compressed and stores elastic potential energy.

[0029] Once the lens is fully inside the enclosure, the insertion process stops, and the elastic potential energy of the return spring 703 begins to release. Its rebound force pushes the sliding clamp 701 to slide away from each other again. The linkage rod 704 and the hinge connecting rod 705 then reset, causing the arc-shaped clamp 706 and the clamping claw 707 to tighten again. At this time, the silicone pad is moderately compressed and deformed due to the presence of the lens, tightly adhering to the lens surface and filling the gap between the fixing groove and the lens. This not only prevents the lens from sliding through the friction of the silicone, achieving a stable clamping, but also uses the cushioning effect of the pad to prevent the lens surface from being scratched by hard parts.

[0030] Furthermore, the drive assembly includes a threaded hole opened on the sliding seat 3, and a drive motor 4 fixedly mounted on the base 1. A threaded rod 5 is fixedly mounted on the drive end of the drive motor 4. The other end of the threaded rod 5 passes through the threaded hole, and a limiting block 6 is fixedly mounted on the other end of the threaded rod 5. The diameter of the limiting block 6 is larger than the diameter of the threaded rod 5.

[0031] Furthermore, symmetrical limit grooves are provided on one side of the sliding seat 3. The limit grooves cooperate with the hollow bracket 2 and rise or fall along the height direction of the hollow bracket 2 during the movement state.

[0032] The threaded hole on the sliding seat 3 is engaged with the outer circumferential thread of the threaded rod 5;

[0033] When the drive assembly is in its initial state, the drive motor 4 is not started, the threaded rod 5 is stationary and its outer circumference is in threaded engagement with the threaded hole on the sliding seat 3, and the limit block 6 is located on the side of the sliding seat 3 away from the drive motor 4 because its diameter is larger than that of the threaded rod 5. The symmetrical limit groove on the sliding seat 3 and the hollow bracket 2 form an interlocking state. At this time, the sliding seat 3 and the clamping assembly connected to it are in the initial vertical position.

[0034] When the clamping assembly needs to be driven to change its vertical position, the drive motor 4 starts and drives the threaded rod 5 to rotate around its own axis. Since the threaded rod 5 and the threaded hole of the sliding seat 3 are threadedly engaged, the rotational motion of the threaded rod 5 is converted into the linear motion of the sliding seat 3 along the axial direction of the threaded rod 5. At the same time, the limiting groove of the sliding seat 3 and the fitting structure of the hollow bracket 2 restrict the sliding seat 3 from rotating synchronously with the threaded rod 5, forcing the sliding seat 3 to only make vertical lifting and lowering movements along the height direction of the hollow bracket 2, and the clamping assembly moves synchronously with the sliding seat 3.

[0035] During the movement of the sliding seat 3, the limiting block 6 always axially limits the sliding seat 3 to prevent it from detaching from the threaded rod 5. When the clamping assembly reaches the target vertical position, the drive motor 4 stops working, the threaded rod 5 stops rotating, and the sliding seat 3 maintains its current position under the self-locking action of the thread and the cooperation of the limiting groove and the hollow bracket 2, thus completing the drive process.

[0036] In summary, the base 1 and the hollow bracket 2 remain vertically fixed, providing stable support for the entire device. The clamping assembly is slidably connected to the hollow bracket 2 via the sliding seat 3. During operation, under normal conditions, the return spring 703 pushes the sliding clamp 701 and the linkage rod 704 to form a circular encircling ring with the arc-shaped clamp 706 and the two clamping claws 707. When a lens is placed, the lens compression causes the sliding clamp 701 and the linkage rod 704 to contract and compress the return spring 703. After placement, the rebound force of the return spring 703 tightens the encircling ring. The soft inner wall component achieves stable clamping and avoids damage to the lens. In the drive assembly, the drive motor 4 is fixed to the base 1, and its threaded rod 5 at the drive end engages with the threaded hole of the sliding seat 3. The limiting block 6 provides axial limiting, and the limiting groove of the sliding seat 3 engages with the hollow bracket 2 to restrict rotation. During operation, the drive motor 4 drives the threaded rod 5 to rotate, and through the threaded engagement and limiting structure, the sliding seat 3 drives the clamping assembly to rise and fall along the height direction of the hollow bracket 2. After reaching the target position, the drive motor 4 stops working, and the sliding seat 3 maintains its position under the self-locking of the thread and the limiting engagement. The overall device, through the coordination of the clamping assembly and the drive assembly, achieves stable clamping, protection, and precise vertical position adjustment of the lens.
