Description

Technical Field

[0001] This utility model relates to the field of optical equipment technology, and more specifically, to a parallel push-pull positioning mechanism for optical reflectors. Background Technology

[0002] In modern optical systems, the positional accuracy of optical mirrors plays a decisive role in the propagation path of light and the overall performance of the optical system. To meet the needs of different optical applications, it is often necessary to adjust the parallel displacement of optical mirrors to optimize and calibrate the optical path.

[0003] Currently, the common methods for positioning optical reflectors are mainly manual adjustment and electric adjustment. Manual adjustment usually relies on operators using tools such as screwdrivers and wrenches to fine-tune the adjusting screws on the reflector mounting bracket. This method is cumbersome, the adjustment accuracy is greatly affected by the operator's experience and skill level, it is difficult to achieve high-precision parallel displacement adjustment, and the adjustment efficiency is low, which cannot meet the needs of rapid positioning.

[0004] While electric adjustment improves efficiency and accuracy to some extent, existing electric positioning mechanisms typically use lead screw connections for transmission. Although lead screw connections ensure accuracy, the lack of further limiting components after adjustment makes them susceptible to slight movement due to vibration, affecting the accuracy of the adjustment. Therefore, we propose an optical reflector parallel push-pull positioning mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a parallel push-pull positioning mechanism for optical reflectors to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An optical reflector parallel push-pull positioning mechanism includes a base on which two symmetrical guide rails are fixedly mounted. A servo motor is fixedly mounted at the end of each guide rail, and a precision lead screw is fixedly mounted at the end of the output shaft of each servo motor. A slider is threaded onto the precision lead screw, and the slider is slidably connected to the guide rail. A sliding platform is fixedly mounted on the top of the two sliders, and an electric push rod is fixedly mounted at the center of the bottom surface of the sliding platform. An anti-slip pressure plate is detachably mounted at the end of the telescopic shaft of the electric push rod. An anti-slip plate is mounted on the upper surface of the base, and the anti-slip pressure plate presses against the upper surface of the anti-slip plate for limiting operation.

[0007] Preferably, the base is mounted on the corresponding frame of the optical device, and the two guide rails are parallel to each other.

[0008] Preferably, the guide rail is provided with a groove along the length of the guide rail, and the slider is located in the groove and slidably connected to the groove.

[0009] Preferably, the anti-slip plate is arranged along the length direction of the base, and the length of the anti-slip plate is equal to the length of the guide rail.

[0010] Preferably, the end of the slide away from the servo motor is connected to the outside, and the end of the guide rail away from the servo motor is detachably equipped with an end plate, which is used to seal the end of the slide. This feature prevents the slider from slipping off the end of the groove.

[0011] Preferably, a shaft hole is provided at the center of the end plate, and a protrusion is fixedly installed at the end of the precision lead screw away from the servo motor. The protrusion is located in the shaft hole and is rotatably connected to the shaft hole. This feature utilizes end plates to support the protruding post, ensuring greater structural stability of the precision lead screw during rotation.

[0012] Preferably, the sliding platform is provided with multiple bolt holes for fixing and installing the optical reflector support. A rectangular plate is fixedly installed at the end of the telescopic shaft of the electric push rod, and the anti-slip clamping plate is detachably installed on the bottom surface of the rectangular plate by multiple fastening bolts.

[0013] Preferably, the upper surface of the base is provided with a plurality of positioning protrusions, and a center plate is fixedly installed on both the left and right sides of the anti-slip plate. The center plate is provided with a corresponding number of positioning grooves, and the positioning protrusions are inserted into the positioning grooves. The center plate is fixedly installed on the base by a plurality of fastening screws.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves high-precision parallel displacement of the sliding platform by setting up mutually parallel guide rails, a precision lead screw driven by a servo motor, and a slider that cooperates with it. The servo motor precisely controls the rotation of the precision lead screw, driving the slider to slide smoothly in the groove of the guide rail. Compared with the traditional manual adjustment method, it greatly improves the adjustment efficiency and accuracy, can meet the requirements of fast and accurate optical reflector positioning, and effectively avoids the problems of accuracy error and low efficiency caused by manual operation.

[0015] 2. This utility model achieves reliable positioning after adjustment by installing an electric push rod at the center of the bottom surface of the sliding platform and setting an anti-slip clamping plate at the end of its telescopic shaft, in conjunction with the anti-slip plate on the base. When the optical reflector is adjusted to the correct position, the electric push rod extends to press the anti-slip clamping plate firmly onto the anti-slip plate. Utilizing the friction and clamping force between the two, it effectively prevents slight movement of the sliding platform due to external forces such as vibration. Compared with existing electric positioning mechanisms that lack further limiting components, this greatly improves the adjustment accuracy and stability, ensuring that the optical reflector always remains in the precise position.

[0016] 3. This utility model achieves the stability and reliability of the entire positioning mechanism structure through the cooperation of the end plate, protrusion, and shaft hole at the end of the guide rail, and the insertion and fixing of the anti-slip plate and the base through the positioning protrusion and positioning groove and the fastening screw. The end plate supports the precision lead screw, ensuring the stability of the lead screw during rotation; the installation method of the anti-slip plate and the base ensures that their positions are fixed and not easily loosened, so that the components of the positioning mechanism work together stably during operation, extending the service life of the mechanism, reducing equipment maintenance costs, and also providing a solid structural guarantee for the high-precision positioning of the optical reflector.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Please see Figures 1-5 This utility model provides a technical solution: a parallel push-pull positioning mechanism for an optical reflector, including a base 1, on which two symmetrical guide rails 11 are fixedly installed. The base 1 is installed on the corresponding frame of the optical device. The two guide rails 11 are parallel to each other, providing a stable guiding foundation for the movement of the sliding platform 23. The two parallel guide rails 11 provide a precise movement track for the slider 22, ensuring that the sliding platform 23 remains parallel during translation. This ensures that the optical reflector installed on the sliding platform 23 can achieve high-precision parallel displacement, avoiding tilting or offset of the reflector during movement and improving the accuracy of optical path adjustment of the optical system.

[0020] In this embodiment, a servo motor 2 is fixedly installed at the end of the guide rail 11, and a precision lead screw 20 is fixedly installed at the end of the output shaft of the servo motor 2. A slider 22 is threaded onto the precision lead screw 20, and the slider 22 is slidably connected to the guide rail 11. A sliding platform 23 is fixedly installed on the top of the two sliders 22, providing a reliable mounting carrier for the optical reflector. The servo motor 2 can precisely control the rotation speed and angle according to the instructions of the control system, and convert the rotational motion into linear motion through the precision lead screw 20, driving the slider 22 to slide on the guide rail 11. Compared with the traditional driving method, this setting greatly improves the displacement accuracy and adjustment efficiency of the sliding platform 23, and can meet the high-precision positioning requirements of the optical reflector.

[0021] Specifically, an electric push rod 24 is fixedly installed at the center of the bottom surface of the sliding platform 23. An anti-slip clamping plate 242 is detachably installed at the end of the telescopic shaft of the electric push rod 24. An anti-slip plate 15 is installed on the upper surface of the base 1. The anti-slip clamping plate 242 presses against the upper surface of the anti-slip plate 15 for limiting operation, achieving reliable locking after the optical reflector is positioned. When the optical reflector is adjusted to the appropriate position, the electric push rod 24 extends, causing the anti-slip clamping plate 242 to press tightly against the anti-slip plate 15. Utilizing the friction and clamping force between the two, displacement of the sliding platform 23 due to vibration or other external forces is effectively prevented. Compared with traditional positioning mechanisms, this greatly improves the stability and accuracy of positioning.

[0022] Specifically, a groove 12 is provided inside the guide rail 11 along its length. The slider 22 is located inside the groove 12 and slidably connected to it, providing precise limiting and guidance for the movement of the slider 22. The groove 12 restricts the movement direction of the slider 22, allowing it to slide only along the length of the guide rail 11, further improving the straightness and parallelism of the sliding platform 23 and ensuring the accuracy of the optical reflector during the positioning process.

[0023] Furthermore, the anti-slip plate 15 is arranged along the length of the base 1, and its length is equal to that of the guide rail 11, ensuring effective limiting and fixing throughout the entire movement range of the sliding platform 23. No matter where the sliding platform 23 moves, after the electric push rod 24 extends, the anti-slip clamping plate 242 can contact the anti-slip plate 15 and generate sufficient friction, ensuring that the optical reflector can be reliably locked in any position, thus improving the applicability and reliability of the positioning mechanism.

[0024] Furthermore, the end of the slide groove 12 furthest from the servo motor 2 is connected to the outside. An end plate 13 is detachably mounted on the end of the guide rail 11 furthest from the servo motor 2. The end plate 13 is used to seal the end of the slide groove 12, preventing the slider 22 from slipping off the end of the slide groove 12 and ensuring the safety of the positioning mechanism. The sealing function of the end plate 13 provides a limit to the movement of the slider 22, preventing it from sliding off the guide rail 11 due to operational errors or other reasons, thereby damaging the positioning mechanism or affecting the positioning accuracy of the optical reflector.

[0025] It is worth noting that a shaft hole 131 is provided at the center of the end plate 13, and a protrusion 21 is fixedly installed at the end of the precision lead screw 20 away from the servo motor 2. The protrusion 21 is located inside the shaft hole 131 and is rotatably connected to the shaft hole 131, providing an additional support point for the precision lead screw 20. This arrangement reduces the shaking and deformation of the precision lead screw 20 during rotation, ensuring the stability and accuracy of the lead screw transmission, thereby improving the displacement accuracy of the sliding platform 23 and making the positioning of the optical reflector more precise and reliable.

[0026] like Figure 4 As shown, the sliding platform 23 is provided with multiple bolt holes 231. The bolt holes 231 are used for the fixed installation of the optical mirror support, which facilitates the fixed installation of the optical mirror support. Optical mirror supports of different specifications and models can be connected to the bolt holes 231 by bolts to achieve quick installation and disassembly, improve the versatility of the positioning mechanism, adapt to the installation requirements of various optical mirrors, and reduce the difficulty of equipment replacement and maintenance.

[0027] like Figure 5As shown, a rectangular plate 241 is fixedly installed at the end of the telescopic shaft of the electric push rod 24. The anti-slip clamping plate 242 is detachably installed on the bottom surface of the rectangular plate 241 by multiple fastening bolts. When the anti-slip clamping plate 242 is worn or needs to be replaced, it can be replaced simply by unscrewing the fastening bolts, which facilitates the maintenance of the equipment and also ensures the clamping effect between the anti-slip clamping plate 242 and the anti-slip plate 15, ensuring the reliability of the optical reflector positioning.

[0028] like Figure 3 As shown, multiple positioning protrusions 10 are provided on the upper surface of the base 1. A center plate 14 is fixedly installed on both the left and right sides of the anti-slip plate 15. The center plate 14 is provided with a corresponding number of positioning grooves 141. The positioning protrusions 10 and the positioning grooves 141 are interlocked and engaged. The center plate 14 is fixedly installed on the base 1 by multiple fastening screws, ensuring the positional accuracy of the anti-slip plate 15 during installation. The anti-slip plate 15 is then fixedly installed on the base 1 by fastening screws, ensuring its stability during the limit operation process and improving the reliability of the entire positioning mechanism.

[0029] Finally, it should be noted that the servo motor 2, electric push rod 24, corresponding control system and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and adapted controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0030] When using the optical reflector parallel push-pull positioning mechanism of this utility model, firstly, the optical reflector is fixedly installed on the sliding platform 23, and then the base 1 is installed on the corresponding frame of the optical device to ensure the stability of the entire mechanism. After the preparation work is completed, according to the optical path adjustment requirements of the optical system, the control system sends a command to the servo motor 2. The servo motor 2 precisely controls the speed and angle according to the command, drives the precision lead screw 20 to rotate, and the slider 22, which is threadedly connected to the precision lead screw 20, slides smoothly in the groove 12 of the guide rail 11, thereby driving the sliding platform 23 to move parallel along the direction of the guide rail 11, realizing the displacement adjustment of the optical reflector. Once the optical reflector moves to the target position, the electric push rod 24 is activated, and its telescopic shaft extends, driving the anti-slip pressure plate 242 to move downward and press firmly against the anti-slip plate 15. The friction and pressure force are used to lock the sliding platform 23 firmly, preventing it from shifting due to vibration or other factors. In routine maintenance, if the anti-slip clamping plate 242 is worn, the fastening bolts can be unscrewed and it can be removed from the rectangular plate 241 for replacement. In addition, the end plate 13 can prevent the slider 22 from slipping off the end of the slide groove 12, ensuring the safe operation of the mechanism. Its support for the precision lead screw 20 also ensures the accuracy and stability of the entire adjustment process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
