Description

A novel detachable lens pressing base Technical Field

[0001] This utility model relates to the field of lens pressing technology, and in particular to a novel detachable lens pressing base. Background Technology

[0002] Currently, most lens pressing mounts on the market adopt a one-piece all-metal design, which has several limitations. First, the bottom support surface of this design is mostly concave, making it difficult to control flatness. Adjusting the flatness of the pressing machine requires the use of parallel fixtures, which not only increases the difficulty of adjustment but may also increase flatness tolerances. Second, one-piece pressing mounts are mostly custom-made, only compatible with specific lenses, making it difficult to meet the needs of multiple lenses. Switching between camera models is cumbersome, requiring readjustment of flatness, significantly increasing time costs. Third, for lenses with a square base, the mount is difficult to manufacture, and the surface roughness is hard to control, making it difficult to guarantee manufacturing quality. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to propose a novel detachable lens pressing base, which can solve at least one of the technical problems mentioned in the background art.

[0004] According to one aspect of the present invention, a novel detachable lens pressing base is provided, applied to a pressing machine, the base comprising:

[0005] The base body has a connecting part on one side, and a flat surface on the top of the connecting part, which is parallel to the reference surface of the press machine platform.

[0006] The upper sleeve is fitted onto the top of the connecting part, and the contact surface between the upper sleeve and the connecting part is parallel to the plane; the contact surface is provided with a hollow part, which is used to fix the frame so that the image side of the frame abuts against the plane.

[0007] In the above technical solution, the novel detachable lens pressing base consists of two parts: a base body and an upper sleeve. It aims to overcome the limitations of traditional one-piece all-metal bases in terms of compatibility, flatness control, and processing difficulty. One side of the base body has a connecting part, the top plane of which is parallel to the reference plane of the pressing machine. The upper sleeve is fitted onto the top of the connecting part, with its contact surface parallel to the plane and featuring a cutout for fixing the lens frame and ensuring the image side abuts the plane. This design improves compatibility, simplifies the debugging process, and reduces processing difficulty through a detachable structure. The base body is fixed to the pressing machine, ensuring the top plane of its connecting part is parallel to the machine's reference plane. The upper sleeve is fitted onto the top of the connecting part, aligning the contact surface parallel to the plane. The upper sleeve is fixed using a positioning device (such as screws or clips) to ensure connection stability. The lens frame is placed in the cutout of the upper sleeve and secured using the upper sleeve's fixing structure (such as a clamping device or magnetic attraction). The image side of the lens frame is ensured to be tightly abutted against the top plane of the base body, guaranteeing consistent optical performance. During the model switchover phase, remove the upper cover and replace it with an upper cover module adapted to the new model (if replacement is necessary). Ensure that the contact surface of the new upper cover is parallel to the plane of the base body; there is no need to readjust the flatness of the base body. After installing and securing the new upper cover, repeat the operation during the usage phase.

[0008] This modular design allows for universal base compatibility, requiring only the top sleeve to adapt to different frame sizes, avoiding the difficulties of model switching caused by customization in traditional one-piece bases. The base body's plane is directly parallel and aligned with the machine's reference plane, eliminating the need for parallel fixtures and reducing tolerance overlap. The parallel design of the top sleeve's contact surface with the base body further ensures precise fit between the image side of the frame and the reference plane. The modular design breaks down the complex structure into independent modules; the base body only needs to ensure flatness, while the hollowed-out parts of the top sleeve can be individually optimized for processing. The difficulty of roughness control at the bottom of square frames is significantly reduced. When switching models, there is no need to readjust the flatness of the base body; only the top sleeve needs to be replaced and its fixed position adjusted, saving approximately 60%-70% of the debugging time. The modular design supports quick top sleeve replacement, reducing downtime during model switching; it also facilitates mass production and inventory management, reducing production costs. Top sleeves can be designed separately for special frames (such as oversized or irregularly shaped frames), eliminating the need to redevelop the base body and reducing R&D costs. The split structure reduces quality fluctuations caused by customized processing and improves overall pressing accuracy and product consistency.

[0009] In some embodiments, the base body and the upper sleeve are fixed together by screws.

[0010] In the above technical solution, the novel detachable lens pressing base consists of two parts: a base body and an upper sleeve, with the base body and upper sleeve fixed together by screws. This screw fixing ensures the stability and reliability of the connection during use, preventing accuracy degradation or quality issues caused by loose connections. The screw fixing method also makes disassembly and replacement of the upper sleeve more convenient, facilitating daily maintenance and component replacement, reducing maintenance costs and downtime. When switching camera models, loosen the screws, remove the upper sleeve, and replace it with an upper sleeve module adapted to the new model. Ensure the contact surface of the new upper sleeve is parallel to the plane of the base body; there is no need to readjust the flatness of the base body. After installing and fixing the new upper sleeve, repeat the operation.

[0011] In some embodiments, the base body and the upper sleeve are connected by threads.

[0012] In the above technical solution, as an optional option, the base body and the upper sleeve are connected by a threaded connection. This ensures the stability and reliability of the connection during use, avoiding precision degradation or quality problems caused by loose connections, and guaranteeing the continuity and stability of production. Furthermore, the threaded connection allows for adjustment of the upper sleeve's position as needed, further improving the base's flexibility and adaptability, and better meeting the requirements of different production scenarios and processes. The base body is fixed to the press machine, ensuring that the top plane of its connecting part is parallel to the machine's reference plane. The upper sleeve is then fitted onto the top of the connecting part, and rotated by aligning the threads to ensure a tight connection between the upper sleeve and the base body, ensuring that the contact surface is parallel to the plane.

[0013] In some embodiments, the cutout portion is provided with a plurality of positioning grooves, which are used to position the mirror frame.

[0014] In the above technical solution, the hollowed-out section is provided with several positioning grooves. These grooves are used to precisely position the frame, ensuring that the image side of the frame abuts against the top plane of the base body. This design not only improves compatibility and simplifies the debugging process but also reduces manufacturing difficulty. During use, the frame is placed on the hollowed-out section of the upper sleeve, and the positioning grooves within the hollowed-out section precisely position the frame, effectively reducing positional deviations during frame installation and improving assembly accuracy and product yield.

[0015] In some embodiments, the base is fixed to the press platform by screws.

[0016] In the above technical solution, screws are used to fix the base body to the press table, ensuring that the top plane of its connecting part is parallel to the reference plane of the press table. The base and the press table are fixed with screws to ensure the stability of the base during use, avoiding the decrease in accuracy or quality problems caused by the base loosening, and further improving the stability and reliability of production.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] Example 1

[0024] Please refer to Figure 1. A novel detachable lens pressing base is applied to a pressing machine. The base includes: a base body 1, on one side of which a connecting part 11 is provided. The top of the connecting part 11 is provided with a plane A, which is parallel to the reference plane of the pressing machine (not shown in the figure). Here, the reference plane refers to the precise positioning reference provided on the pressing machine for the workpiece or mold during the pressing process.

[0025] The upper sleeve 2 is fitted onto the top of the connecting part 11, and the contact surface between the upper sleeve 2 and the connecting part 11 is parallel to the plane A; the contact surface is provided with a hollow part 21, which is used to fix the frame (not shown in the figure) so that the image side of the frame abuts against the plane A.

[0026] In this embodiment, the base 1 is rectangular in shape and made of high-strength aluminum alloy. A connecting part 11 extends outward from one side, and this connecting part 11 is a columnar structure. The top of the connecting part 11 is precision-machined to form a smooth and flat plane A. This plane is parallel to the reference plane of the pressing machine, with an error controlled within ±0.02 mm. Calibration is performed using a high-precision level to ensure that the top plane A of the connecting part is precisely aligned with the reference plane of the pressing machine during installation, thus providing a stable reference for subsequent frame fixing. The upper sleeve 2 is a cylindrical structure made of stainless steel, possessing good wear resistance and deformation resistance. The contact surface between the upper sleeve 2 and the connecting part 11 is specially treated to remain parallel to the plane, ensuring a tight fit and ensuring even force distribution during upper sleeve installation, preventing tilting or loosening. A hollow part 21 is provided at the center of the top of the upper sleeve 2, its shape matching the mounting part of the frame, to accommodate and fix the frame. The image side of the mirror frame is tightly abutted against the top plane A of the connecting part 11. Since plane A is parallel to the reference plane of the press machine, the mirror frame is accurately positioned in three-dimensional space, ensuring the accuracy and quality of the mirror frame processing and avoiding processing errors caused by mirror frame offset or instability.

[0027] In this embodiment, the base body 1 and the upper sleeve 2 are fixed together by screws (not shown in the figure). To ensure the stability and reliability of the connection between the upper sleeve and the base body, the base body and the upper sleeve are reinforced by fixing them together with screws. Referring to Figure 2, two threaded holes 12 are symmetrically arranged on both sides of the connecting part 11 of the base body 1, and two through holes 22 are provided at the corresponding positions of the upper sleeve 2. During installation, the screws are screwed into the threaded holes 12 of the base body 1 through the through holes 22 of the upper sleeve 2. By tightening the screws, the upper sleeve 2 and the base body 2 are tightly connected, further enhancing the connection strength between the two, preventing the upper sleeve from loosening due to severe vibration during the pressing of the frame, thereby ensuring the stability of the frame's fixed position and improving the quality and yield of the frame processing.

[0028] In this embodiment, as an optional implementation, the base body and the upper sleeve are connected by a thread. As an optional solution, the base body and the upper sleeve are connected by a thread (no corresponding drawings are provided for this example, but the specific principle is described later). An external thread is machined on the outer wall of the connecting part 11 of the base body 1, with a thread accuracy of 6g tolerance grade, a pitch of 1.5 mm, and a right-hand thread direction. The inner wall of the upper sleeve 2 is machined with a matching internal thread, also with an internal thread accuracy of 6H tolerance grade. During installation, the upper sleeve 2 is aligned with the connecting part 11, and by rotating the upper sleeve 2, the internal and external threads mesh, achieving a tight connection between the upper sleeve 2 and the base body 1. This threaded connection method has advantages such as simple structure, reliable connection, and convenient assembly and disassembly. It can meet the needs of rapid installation and disassembly of the fixing device during the frame manufacturing process. At the same time, through reasonable design of the thread parameters, it ensures that the connection part has sufficient strength and rigidity to withstand various forces generated during the pressing process. In addition, to further improve the stability of the threaded connection, anti-loosening devices, such as spring washers or thread-locking adhesive, can be installed at the threaded connection to prevent the threads from loosening due to vibration or impact, thereby ensuring the long-term stability of the frame's fixed position.

[0029] In this embodiment, referring to Figure 3, the hollowed-out portion 21 is provided with a plurality of positioning grooves 211, which are used to position the frame. A plurality of positioning grooves 211 are evenly distributed around the hollowed-out portion, and these positioning grooves 211 are arc-shaped and match the positioning protrusions on the edge of the frame. When the frame is inserted into the hollowed-out portion 21, the positioning protrusions on the edge of the frame will accurately embed into the positioning grooves 211, thereby achieving precise positioning of the frame in multiple directions. The positioning grooves not only improve the accuracy of frame installation but also enhance the connection stability between the frame and the upper sleeve. Furthermore, to further improve the fixing effect of the frame, anti-slip textures can be added to the bottom of the positioning grooves, increasing the friction between the frame and the positioning grooves, preventing the frame from sliding or rotating after installation, ensuring the stability of the frame during the pressing process, effectively avoiding processing errors caused by frame position deviation, and improving the quality and yield of frame processing.

[0030] In this embodiment, referring to Figure 1, the base 1 is fixed to the pressing machine platform with screws. Four mounting holes 13 are provided at the four corners of the bottom of the base 1 body. These mounting holes 13 are through holes with precision-machined walls to ensure a tight fit with the screws. Correspondingly, the pressing machine platform has four threaded holes, each corresponding to one of the mounting holes on the base body. During installation, the base body is placed on the pressing machine platform, aligning the top plane of the connecting part of the base body with the reference plane of the pressing machine platform. Then, four high-strength screws (made of alloy steel, strength grade 12.9) are passed through the mounting holes of the base body and screwed into the threaded holes of the pressing machine platform. A torque wrench is then used to tighten the screws to the specified torque value (approximately 25 N·m). This screw fixing method ensures a firm and reliable connection between the base and the pressing machine platform, effectively preventing processing errors caused by base loosening during the frame pressing process. It also facilitates quick disassembly and replacement of the base, improving production efficiency. In addition, another connecting part 14 is provided on the other side of the base 1 for adapting to a pressing machine that uses a clamping method. The bottom plane B of the connecting part 14 is parallel to the plane A. A schematic diagram of the frame installation can be seen in Figure 4, where 1 is the base, 2 is the upper sleeve, and 3 is the frame.

[0031] The above description is only a part of the embodiments of this utility model, and does not limit the scope of protection of this utility model. Any equivalent device or equivalent process transformation made based on the content of this utility model specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this utility model.
