Description

Technical Field

[0001] This utility model relates to the field of lens assembly technology, and in particular to a lens sheet metal pressing fixture. Background Technology

[0002] Lens sheet metal parts are metal frames or housings mounted on camera or camcorder lenses, primarily used to protect the lens and provide structural support. Placed inside the lens frame, the lens sheet metal provides stable structural support, ensuring the lens remains stable in various environments and reducing the likelihood of frame deformation due to external vibrations or pressure.

[0003] In the existing technology, the assembly of sheet metal parts is generally carried out by manually inserting the snap-fit ​​positions into the grooves for gluing or locking. Since the sheet metal parts are relatively thin, it is easy for them to be not locked in place or for the sheet metal parts to tilt and fall out of the grooves during the locking process. Utility Model Content

[0004] The present invention provides a lens sheet metal pressing fixture for pressing sheet metal parts inside the lens frame, which reduces the probability of sheet metal parts not being properly locked or falling off during the locking process and improves assembly efficiency.

[0005] The above-mentioned technical problems are solved by the following technical solutions:

[0006] A lens sheet metal pressing fixture is used to position two sheet metal parts inside a lens. The lens sheet metal pressing fixture includes pressing blocks and elastic connecting components. Two pressing blocks are provided, and the elastic connecting components are connected between the two pressing blocks.

[0007] The two pressure blocks have a first state and a second state, and the elastic connection component enables the two pressure blocks to switch from the first state to the second state;

[0008] When the two pressing blocks are in the first state, there is a first gap between the two pressing blocks; when the two pressing blocks are in the second state, there is a second gap between the two pressing blocks, and the two pressing blocks respectively press against the two sheet metal parts, and the first gap is smaller than the second gap.

[0009] In one embodiment, the opposing sides of the two pressing blocks are respectively configured as an arc-shaped structural surface and a trapezoidal structural surface.

[0010] In one embodiment, the elastic connection assembly includes an elastic element and a plurality of guide posts, a first end of which is fixedly connected to one of the pressing blocks, and a second end of which is slidably connected to another pressing block, so that the two pressing blocks can switch between a first state and a second state;

[0011] The elastic element is elastically clamped between the two pressing blocks and can switch the two pressing blocks from the first state to the second state.

[0012] In one embodiment, another of the pressing blocks is provided with a guide hole that is slidably connected to the guide post;

[0013] The second end face of the guide post is provided with a first threaded hole;

[0014] The resilient connection assembly also includes a screw corresponding to each of the guide posts, the shank of the screw extending into the guide hole and threaded into the first threaded hole, and the nut of the screw being located on the side of another pressure block opposite to the resilient element.

[0015] In one embodiment, another of the pressing blocks has a countersunk hole communicating with the guide hole on the side opposite to the elastic element, and the screw nut is confined within the countersunk hole.

[0016] In one embodiment, the elastic element is a spring sleeved on the guide post.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

They are only for the convenience of describing this application 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 application.

[0034] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] This utility model provides a lens sheet metal pressing fixture, which is used to position and press the two sheet metal parts 200 during the assembly of the two sheet metal parts 200 inside the lens, so as to prevent the sheet metal parts 200 from being misaligned or falling off, and to facilitate the locking and fixing of the sheet metal parts 200.

[0037] like Figures 1-5 As shown, the lens sheet metal pressing fixture includes pressing blocks 1 and elastic connecting components 2. Two pressing blocks 1 are provided, and the elastic connecting components 2 connect the two pressing blocks 1. The two pressing blocks 1 have a first state and a second state. The elastic connecting components 2 can switch the two pressing blocks 1 from the first state to the second state. In the first state, the two pressing blocks 1 have a first distance between them; in the second state, the two pressing blocks 1 have a second distance between them.

[0038] When using this lens sheet metal pressing fixture, the assembler can press the two pressing blocks 1 and overcome the elastic force of the elastic connecting component 2 to switch the two pressing blocks 1 to a first state. When the two pressing blocks 1 are in the first state, they can be installed inside the lens frame 100. After the two pressing blocks 1 are placed inside the lens frame 100, the assembler releases the pressing blocks 1. Under the elastic force of the elastic connecting component 2, the two pressing blocks 1 move away from each other and press against the two sheet metal parts 200 respectively, so that the two sheet metal parts 200 can be positioned inside the lens frame 100 to facilitate the installation of the sheet metal parts 200. It is understood that the first gap is smaller than the second gap.

[0039] This lens sheet metal pressing fixture switches the two pressing blocks 1 from a first state to a second state by using the elastic connecting component 2. After the two pressing blocks are placed inside the lens frame 100, they automatically press against the two sheet metal parts 200 under the elastic force and press and position the two sheet metal parts 200. This ensures that the sheet metal parts 200 can be fixed in place during the locking process, reducing the probability of incomplete locking or the sheet metal parts 200 falling off during the locking process, and improving work quality and efficiency.

[0040] Since one of the two sheet metal parts 200 is arc-shaped and the other is trapezoidal, in order for the two pressing blocks 1 to press the two sheet metal parts 200 respectively, specifically, the opposite sides of the two pressing blocks 1 are respectively set as arc-shaped structural surfaces and trapezoidal structural surfaces. By setting the arc-shaped structural surface that matches the arc-shaped sheet metal part 200 and the trapezoidal structural surface that matches the trapezoidal sheet metal part 200, the two pressing blocks 1 can accurately press the two sheet metal parts 200.

[0041] Furthermore, the opposite ends of the two pressing blocks 1 are both rounded at the corners to avoid scratching the sheet metal part 200.

[0042] Optionally, such as Figures 3-5 As shown, the elastic connection assembly 2 includes an elastic element 22 and multiple guide posts 21. One end of each guide post 21 is fixedly connected to one pressing block 1, and the other end is slidably connected to another pressing block 1, allowing the two pressing blocks 1 to switch between a first state and a second state. The elastic element 22 is elastically clamped between the two pressing blocks 1, enabling the two pressing blocks 1 to switch from the first state to the second state. This structure enables the two pressing blocks 1 to switch between the first and second states, and the elastic element 22 can automatically switch the two pressing blocks 1 from the first state to the second state. The structure is simple and easy to operate.

[0043] Furthermore, another pressing block 1 is provided with a guide hole 11 that is slidably connected to the guide post 21; the end face of the second end of the guide post 21 is provided with a first threaded hole; the elastic connection assembly 2 also includes a screw 23 corresponding to each guide post 21, the screw shank of the screw 23 extends into the guide hole 11 and is screwed into the first threaded hole, and the nut of the screw 23 is limited to the side of the other pressing block 1 away from the elastic element 22, so that the second end of the guide post 21 is slidably connected to the other pressing block 1, and the pressing block 1 is prevented from coming out of the guide post 21.

[0044] To avoid interference between the nut of screw 23 and the corresponding sheet metal part 200, another pressing block 1 is provided with a countersunk hole 12 communicating with the guide hole 11 on the side opposite to the elastic member 22. The nut of screw 23 is confined within the countersunk hole 12, so that the nut of screw 23 does not protrude from the pressing block 1.

[0045] Optionally, the elastic element 22 is configured as a spring sleeved on the guide post 21. The spring has a simple structure, low processing and manufacturing cost, and simple and quick assembly.

[0046] In this embodiment, four guide posts 21 and two springs are provided, with the two springs respectively sleeved on two of the guide posts 21. By providing four guide posts 21, the movement of the two pressing blocks 1 is ensured to be stable, and by sleeved on two of the guide posts 21, the number of parts is reduced while still enabling the two pressing blocks 1 to switch from the first state to the second state.

[0047] Optionally, of the four guide posts 21, two guide posts 21 that are diagonally distributed are used for positioning and guiding, and the other pair of two guide posts 21 that are diagonally distributed are used to mount springs. They can be used for positioning and guiding or not. When only two guide posts 21 are used for positioning and guiding, the other two guide posts 21 that are not used for positioning and guiding can reduce the machining accuracy.

[0048] Optionally, the first end of the guide post 21 is provided with an external thread, and the pressure block 1 fixedly connected to the guide post 21 is provided with a plurality of second threaded holes corresponding to the guide post 21. The second end of the guide post 21 is screwed into the second threaded hole to realize the fixed connection between the guide post 21 and the corresponding pressure block 1.

[0049] To facilitate the operation of the lens sheet metal pressing fixture by the assembly personnel, hand grooves 13 are provided on the opposite sides of the two pressing blocks 1. The assembly personnel can insert their fingers into the hand grooves 13 to press the two pressing blocks 1, making the operation more convenient.

[0050] Optionally, the pressing block 1 is made of plastic to ensure that it will not scratch the sheet metal part 200 when pressing against it. Furthermore, the pressing block 1 can be made of PEEK material (polyetheretherketone), which has excellent mechanical strength and dimensional stability, as well as strong wear resistance and corrosion resistance.

[0051] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0052] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
