Description

Technical Field

[0001] This utility model relates to the field of optical lens processing, specifically a lens positioning fixture for optical instrument manufacturing. Background Technology

[0002] Optical instrument manufacturing requires high precision and technical capabilities, involving multiple disciplines such as optical engineering, mechanical engineering, and electronic engineering. Different optical instruments have different manufacturing requirements. For example, microscopes, telescopes, spectrometers, and lasers all require specific manufacturing processes and professional knowledge to realize their functions and performance. However, when processing lenses on optical instruments, positioning fixtures are needed to position and clamp them in order to improve the accuracy and quality of lens processing.

[0003] Publication No. CN221755879U discloses a lens positioning fixture for optical instrument manufacturing, including a base. Electric telescopic rods are fixedly installed on both sides of the base. The top of the base has two openings with movable slots. A movable block is fixedly connected to the output end of the electric telescopic rod, which passes through the movable slot. The movable block is slidably connected within the movable slot. A fixing plate is fixedly connected to the top of the movable block. The inner side of the fixing plate has a placement slot for lens placement. A protective pad is glued to the inside of the placement slot. By using the placement slot, protective pad, slot, insert, and clamping seat in conjunction, the placement slot provides protection when clamping lenses on optical instruments, reducing frictional damage during lens positioning and fixing. Furthermore, the clamping seat facilitates clamping and fixing of both ends of the lens, thereby improving the accuracy and efficiency of lens processing.

[0004] In the aforementioned prior art, before positioning the lens, it is necessary to determine that the distance between two opposing moving platforms has approached a certain distance before the lens can be stably placed on the platform. Before this, the lens needs to be picked up manually, and the platform needs to be continuously monitored by a person during the movement. There is no time to do anything else during the positioning process. To solve the above problems, we propose a lens positioning fixture for optical instrument manufacturing. Utility Model Content

[0005] The purpose of this invention is to provide a lens positioning fixture for manufacturing optical instruments to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a lens positioning fixture for optical instrument manufacturing includes a base. A motor is fixedly mounted at one end of the base, and a lead screw is fixedly mounted at the output end of the motor. The lead screw is rotatably connected inside the base, and movable platforms are threaded to both ends of the lead screw. Fixed platforms are fixedly connected to the middle of both ends of the upper surface of the base near the edge. Movable supports are slidably connected to both ends of the fixed platforms. Curved plates are fixedly connected to the upper surface of the movable platforms. The movable supports are disposed on the lower side of the curved plates, and protective pads are provided on the upper surface of the movable supports and the inner wall of the curved plates.

[0007] Furthermore: the movable support includes a horizontal plate, and both ends of the horizontal plate are fixedly connected to movable plates in an inverted L shape.

[0008] Furthermore: the upper end of the movable plate is slidably connected to one end of the fixed platform, and the lower end of the movable plate is slidably connected to the upper surface of the base.

[0009] Furthermore, the upper surface of the base is provided with a sliding groove that matches the sliding path of the movable plate, and the connection between the fixed platform and the movable plate, as well as the inner wall of the sliding groove, are provided with an anti-slip layer made of elastic material.

[0010] Furthermore, two openings are provided in the middle of the upper surface of the base, and the positions of the two openings are adapted to the movement path of the movable platform.

[0011] Furthermore, protective plates are fixedly installed on both sides of the upper surface of the base.

[0012] Furthermore, the outer wall of the lead screw is provided with two reverse threads at both ends.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, when placing the lens, the lens is roughly placed in the middle of the movable support. After the motor is started, the rotating screw brings the two movable supports closer to each other. Finally, the lens is clamped in the middle position by the arc plate. During the process, there is no need for continuous manual handling of the lens.

[0015] 2. The movable support can move at both ends of the fixed platform, controlling the distance between the two movable supports to accommodate lenses of different batch sizes. The curvature of the curved plate allows the lens to approach the middle part of the curved plate during movement, making it less likely to fall off the movable support. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-3 The figure shows a preferred embodiment of the present invention, a lens positioning fixture for manufacturing optical instruments, including a base 1, a motor 2 fixedly installed at one end of the base 1, a lead screw 3 fixedly installed at the output end of the motor 2, the lead screw 3 being rotatably connected inside the base 1, and movable platforms 4 being threadedly connected to both ends of the lead screw 3. Fixed platforms 5 are fixedly connected to the middle of both ends of the upper surface of the base 1 near the edge, and movable supports 6 are slidably connected to both ends of the fixed platforms 5. Arc plates 7 are fixedly connected to the upper surface of the movable platforms 4, and the movable supports 6 are disposed on the lower side of the arc plates 7. Pads 8 are provided on the upper surface of the movable supports 6 and the inner wall of the arc plates 7.

[0022] It should be noted that the movable support 6 includes a horizontal plate 9. The upper part of the two horizontal plates 9 can be used to place the lens. In order to stabilize the position of the horizontal plate 9, both ends of the horizontal plate 9 are fixedly connected to a movable plate 10 in the shape of an inverted L.

[0023] The upper end of the movable plate 10 is slidably connected to one end of the fixed platform 5, and the lower end of the movable plate 10 is slidably connected to the upper surface of the base 1.

[0024] Specifically, the upper surface of the base 1 is provided with a groove 11 that matches the sliding path of the movable plate 10. The connection between the fixed platform 5 and the movable plate 10, as well as the inner wall of the groove 11, are provided with an anti-slip layer made of elastic material. The anti-slip layer can be made of silicone or rubber and has a thickness of 1-3mm.

[0025] The base 1 has two openings 12 in the middle of its upper surface for the movable platform 4 to move. The positions of the two openings 12 are adapted to the movement path of the movable platform 4.

[0026] To prevent the lens from falling out of the base 1, protective plates 13 are fixedly installed on both sides of the upper surface of the base 1.

[0027] The lead screw 3 has two reverse threads at both ends of its outer wall, so that when the motor 2 starts, the rotating lead screw 3 causes the two movable platforms 4 to move closer or further apart.

[0028] In this embodiment, before fixing the lens, the movable support 6 needs to be manually pushed to keep the distance between the two horizontal plates 9 within an appropriate range for placing the lens. When placing the lens, the lens is roughly placed in the middle of the movable support 6. After the motor 2 starts, the rotating lead screw 3 brings the two movable platforms 4 closer to each other. Finally, the curved plate 7 clamps the lens in the middle position. It should be noted that the curvature of the curved plate 7 allows the lens to approach the middle part of the curvature of the curved plate 7 during movement, making it less likely to fall off the movable support 6. When clamping, the pressure sensor inside the curved plate 7 stops the motor 2 when the lens is pushed and the pressure reaches the set value, thus maintaining the fixation of the lens.

[0029] Finally, it should be noted that in the description of this utility model, the terms "vertical," "upper," "lower," "horizontal," 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.

[0030] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "install", "connect", and "connection" 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; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
