Description

Technical Field

[0001] This utility model relates to the field of optomechanical system assembly technology, and in particular to a stable platform-type optomechanical system balancing and calibration device. Background Technology

[0002] A stabilized platform-type optomechanical system is a key component of an optoelectronic system. It is used to accurately and quickly track targets and to complete the autonomous search, identification, and tracking of targets. The main task of the stabilized platform-type optomechanical system is to isolate overall disturbances and ensure that the optoelectronic detection equipment remains stable relative to the inertial space. At the same time, it receives control commands fed back by the target detector after processing. The control commands drive the platform motor to ensure the stability of the platform and the accurate tracking of the target by the detector. The stabilized platform-type optomechanical system adopts a two-axis, two-frame design. The laser signal receiving and processing equipment is installed in the inner frame to ensure that the optical axis is not affected by external and frame disturbances. The optical system of the stabilized platform-type optomechanical system overcomes the product optical axis jitter caused by overall motion through the stabilized platform, achieving the effect of stable tracking and locking of the target.

[0003] In existing technologies, stabilization platforms can experience shaft eccentricity due to design errors, material defects, and machining and assembly errors, leading to static imbalance. If this imbalance is too large, it can cause disturbances in the optical axis, resulting in unstable output target signals and affecting the accuracy and reliability of a weapon. Therefore, balancing, or equilibrium adjustment, is necessary during production. On-the-fly balancing is a crucial step in the assembly and adjustment process of stabilization platform products.

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a stable platform-type optical-mechanical system balancing and calibration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stabilization platform-type optical-mechanical system random balancing adjustment device includes a base plate and two support plates. The two support plates are respectively fixedly connected to the upper surface of the base plate. The inner walls of the two support plates are rotatably connected to connecting shafts. The corresponding sides of the two connecting shafts are simultaneously fixedly connected to outer frame seats. The inner wall of the outer frame seats is rotatably connected to a connecting cylinder. One end of the connecting cylinder is fixedly connected to a clamping seat. The inner wall of the clamping seat is fixedly connected to a clamping ring. A rotating ring is rotatably provided on the side wall of the clamping seat located outside the clamping ring. A gap is provided between the clamping ring and the rotating ring. The clamping ring has multiple grooves circumferentially formed inside. The inner walls of the multiple grooves are respectively fixedly connected to springs. The ends of the springs are pressed against clamping posts. The clamping ring has notches on the inner walls of the multiple grooves. Clamping blocks are slidably provided on the inner walls of the multiple notches. The ends of the multiple clamping posts extend into the interior of the notches and are fixedly connected to the clamping blocks.

[0006] Preferably, a handwheel is fixedly connected to the end of the connecting cylinder away from the clamping seat.

[0007] Preferably, the connection between the connecting cylinder and the clamping seat is provided with a mounting flange, and the inner wall of the clamping seat is provided with multiple mounting threaded holes.

[0008] Preferably, a plurality of connecting plates are fixedly connected around the side wall of the rotating ring, an annular groove is provided on the side wall of the clamping seat, a guide slider is fixedly connected to the inner wall of the connecting plate, the guide slider is slidably disposed on the inner wall of the annular groove, the guide slider is configured as a trapezoid, and the inner wall of the annular groove matches the guide slider.

[0009] Preferably, the top inner wall of the support plate is threaded with a bolt, and a limiting post is fixedly connected to one end of the bolt relative to the outer frame seat.

[0010] Preferably, a vertical limiting block is fixedly connected to the upper surface of the base plate, and the side wall of the clamping seat is fitted onto the side wall of the vertical limiting block.

[0011] Compared with the prior art, this utility model provides a stable platform-type optomechanical system random balancing adjustment device, which has the following beneficial effects: 1. This stabilizing platform-type optomechanical system adaptive balancing device can adjust the tension of the spring by rotating the rotating ring and adjusting the gap between the clamping ring and the rotating ring, thereby changing the clamping state of the optomechanical system components. The rotating ring pushes the clamping column to compress the spring, which in turn moves the clamping blocks, causing multiple clamping blocks to converge towards the center synchronously and fit tightly against the outer wall of the optomechanical system components, achieving adaptive clamping and fixing, and adapting to optomechanical components of different sizes.

[0012] 2. The stabilizing platform-type optomechanical system's on-demand balancing device has a connecting cylinder rotatably connected to the inner wall of the outer frame. The connecting cylinder can rotate around its own axis to achieve circumferential angle adjustment of the optomechanical system. The connection between the connecting cylinder and the clamping seat is provided with a mounting flange. The inner wall of the clamping seat has multiple mounting threaded holes. By bolting the mounting flange and the threaded holes, the connection between the connecting cylinder and the clamping seat can be strengthened, ensuring structural stability during the adjustment process.

[0013] 3. The stabilizing platform-type optomechanical system's on-demand balancing device can release the outer frame by loosening the bolts connecting the inner wall of the top of the support plate and removing the fixing to the outer frame. This allows the outer frame to rotate along the connecting shaft. By driving the connecting cylinder with a handwheel, the clamping base and the optomechanical system can rotate circumferentially, thus adjusting the angle of the clamped optomechanical system components within the clamping ring space.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4A stable platform-type optical-mechanical system balancing and calibration device includes a base plate 1 and two support plates 2. The two support plates 2 are fixedly connected to the upper surface of the base plate 1. The inner walls of the two support plates 2 are rotatably connected to connecting shafts 3. The corresponding sides of the two connecting shafts 3 are simultaneously fixedly connected to outer frame seats 4. The inner wall of the outer frame seats 4 is rotatably connected to connecting cylinders 5. One end of the connecting cylinder 5 is fixedly connected to a clamping seat 7. The inner wall of the clamping seat 7 is fixedly connected to a clamping ring 8. A rotating ring 9 is rotatably provided on the side wall of the clamping seat 7 outside the clamping ring 8. There is a gap between the clamping ring 8 and the rotating ring 9. The interior of the clamping ring 8 has multiple grooves. The inner walls of the multiple grooves are fixedly connected to springs 10. The ends of the springs 10 are pressed with clamping posts 11. The inner walls of the multiple grooves of the clamping ring 8 have notches. The inner walls of the multiple notches are slidably provided with clamping blocks 12. The ends of the multiple clamping posts 11 extend into the interior of the notches and are fixedly connected to the clamping blocks 12.

[0018] A handwheel 6 is fixedly connected to the end of the connecting cylinder 5 away from the clamping seat 7. A mounting flange is provided at the connection between the connecting cylinder 5 and the clamping seat 7. Multiple mounting threaded holes are opened around the inner wall of the clamping seat 7.

[0019] The top inner wall of the support plate 2 is threaded with a bolt 15. One end of the bolt 15 is fixedly connected to a limit post 16 relative to the outer frame seat 4. The inner wall of the outer frame seat 4 is provided with multiple limit grooves. The limit post 16 is inserted into the inside of the limit groove. The upper surface of the base plate 1 is fixedly connected with a vertical limit block 17. The side wall of the clamping seat 7 is fitted onto the side wall of the vertical limit block 17.

[0020] The base plate 1 serves as the fundamental load-bearing component of the entire device, providing a stable mounting reference surface for all functional structures. Two support plates 2 are fixedly connected to the upper surface of the base plate 1, and the connecting shaft 3 rotatably connected to its inner wall provides rotational support for the outer frame base 4, enabling the outer frame base 4 to rotate horizontally around the connecting shaft 3, thereby achieving horizontal angle adjustment of the optomechanical system. The vertical limiting block 17 fixedly connected to the upper surface of the base plate 1, through its fit with the side wall of the clamping seat 7, provides a limit for the initial position of the outer frame base 4, preventing the device from shifting before adjustment.

[0021] The inner wall of the outer frame 4 is rotatably connected to a connecting cylinder 5, which can rotate around its own axis. One end of the connecting cylinder 5 is fixedly connected to a clamping seat 7 for clamping optical and mechanical system components, and the other end is fixedly connected to a handwheel 6 for the operator to manually drive the connecting cylinder 5 to rotate, thereby realizing the circumferential angle adjustment of the optical and mechanical system. A mounting flange is provided at the connection between the connecting cylinder 5 and the clamping seat 7. Multiple mounting threaded holes are opened around the inner wall of the clamping seat 7. By bolting the mounting flange and the threaded holes, the connection between the connecting cylinder 5 and the clamping seat 7 can be strengthened, ensuring structural stability during the adjustment process.

[0022] A clamping ring 8 is fixedly connected to the inner wall of the clamping base 7. A gap is provided between the clamping ring 8 and the rotating ring 9. A spring 10 is fixedly connected in multiple grooves that are opened around the inside of the clamping ring 8. A clamping post 11 is pressed against the end of the spring 10. The end of the clamping post 11 extends into the recess of the clamping ring 8 and is fixedly connected to the clamping pressure block 12. When clamping the optical-mechanical system component, the component is placed inside the clamping ring 8. The rotating ring 9 is rotated. By adjusting the gap between the clamping ring 8 and the rotating ring 9, the tension of the spring 10 can be adjusted, thereby changing the clamping state of the optical-mechanical system component. The rotating ring 9 pushes the clamping post 11 to compress the spring 10 and drive the clamping pressure block 12 to move. This causes multiple clamping pressure blocks 12 to converge towards the center synchronously and fit tightly against the outer wall of the optical-mechanical system component, achieving self-adaptive clamping and fixing, and adapting to optical-mechanical components of different sizes.

[0023] When random balancing is required, loosen the bolt 15 threaded on the inner wall of the top of the support plate 2. The limiting post 16 at one end of the bolt 15 will exit from the limiting groove of the outer frame seat 4, releasing the fixation of the outer frame seat 4. At this time, the outer frame seat 4 can be rotated along the connecting shaft 3. The angle can be adjusted according to the usage requirements. The connecting cylinder 5 is driven by the handwheel 6 to drive the clamping seat 7 and the optical-mechanical system to rotate circumferentially. The angle of the clamping optical-mechanical system components in the clamping ring 8 space can be adjusted. During the adjustment process, the elastic force of the spring 10 keeps the clamping block 12 pressing the optical-mechanical components, ensuring that the components do not loosen or shift during the adjustment process. After the optical-mechanical system is adjusted to the required balance position, rotate the bolt 15 in the opposite direction so that the limiting post 16 is inserted into the corresponding limiting groove of the outer frame seat 4. The outer frame seat 4 is then fixed again, completing the random balancing.

[0024] The entire device achieves all-round angle adjustment of the optomechanical system through the multi-dimensional rotation structure of the connecting shaft 3 and the connecting cylinder 5; the adaptive clamping mechanism composed of spring 10, clamping column 11 and clamping pressure block 12 ensures the stable clamping of the optomechanical components; the limiting structure of bolt 15 and limiting column 16 achieves the fixed position after adjustment. The coordinated cooperation of each structure ensures the accuracy and flexibility of the optomechanical system adjustment, and improves the adaptability and stability of the device, perfectly meeting the usage requirements of the stable platform type optomechanical system for on-the-fly balance adjustment.

[0025] To ensure smooth sliding, such as Figure 1-4 As shown, multiple connecting plates 13 are fixedly connected around the side wall of the rotating ring 9, and an annular groove is provided on the side wall of the clamping seat 7. A guide slider 14 is fixedly connected to the inner wall of the connecting plate 13. The guide slider 14 is slidably disposed on the inner wall of the annular groove. The guide slider 14 is trapezoidal, and the inner wall of the annular groove matches the guide slider 14.

[0026] The rotating ring 9 drives the guide slider 14 to slide along the annular groove of the clamping seat 7 through the connecting plate 13 fixed around the side wall. The guide slider 14 is set in a trapezoidal shape and matches the annular groove to ensure smooth sliding.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
