The simulated star map is used to test the working status of related equipment such as navigation and positioning.
[0003] Static image simulation equipment has an unparalleled advantage in position accuracy, so it is widely used in the testing of high-precision graphic recognition and positioning equipment. Static graphic simulation equipment uses a physical real simulation method, with the image precisely etched on the imaging plate as the target image. The target image is modulated into the image that the device needs to collect through the optical system.
[0004] For static graphics simulation equipment, if the position of the star map needs to be corrected, the equipment needs to have the function of adjusting the position of the star point plate in multiple directions externally. At present, the position accuracy of the target imaging plate on the optical simulator, that is, the star point plate, is usually guaranteed by machining accuracy. According to usage experience, the star point plate that relies on machining accuracy aperture tolerance cannot achieve high precision, and generally requires opening the outer shell of the structure for adjustment, and it is impossible to adjust the position of the star point plate while observing the imaging, which greatly increases the difficulty of adjusting the position of the optical star point plate.
[0005] The position of the high-precision optical star point plate needs to be manually fine-tuned, and it needs to be calibrated after a period of use. Therefore, a structure that can facilitate fine-tuning and calibration, and can adjust the position of the star point plate outside the structure when the device is lit, is needed to meet the needs of optical simulation image position adjustment.

[0028] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. Figure 1-3 , a star point plate adjustment mechanism, comprising a propulsion assembly (10), a star point plate mounting assembly (20), a front mounting cover (30), a rear mounting cover (40), a return spring assembly (50), a rear cover (60), a star point plate (70), a light source assembly (80) and a locking top screw (90);

[0030] One side of the rear end mounting cover (40) is fixedly mounted to the front end mounting cover (30), the light source assembly (80) and the locking top screw (90) are sequentially mounted on the rear end mounting cover (40), and the other side of the rear end mounting cover (40) is fixedly mounted to the rear cover (60).
[0031] The propulsion assembly (10) comprises a propulsion screw (11), a screw locking buckle (12), a first roller mounting seat (13) and a first roller (14);
[0032] The first roller (14) is mounted on a first roller mounting seat (13), the first roller mounting seat (13) is connected to the advancing screw (11), and the screw locking buckle (12) is locked on the front mounting cover.
[0033] The return spring assembly (50) comprises a second roller (51), a second roller mounting seat (52), a spring pushing rod (53), a spring (54) and a spring locking buckle (55);
[0034] The second roller (51) is mounted on a second roller mounting seat (52), and the second roller mounting seat (52) is connected to a spring propulsion rod (53).
[0035] The spring (54) is locked in the front end mounting cover (30) by the spring locking buckle (55) and the spring pushing rod (53).
[0036] The operating actions of the star-point plate adjustment mechanism mainly include two actions: axial propulsion and axial tensioning. The propulsion action is achieved by tightening the propulsion screw assembly to drive the roller to push the star-point plate; the tensioning action is achieved by reversely rotating the propulsion screw to drive the roller to retreat, while the spring propulsion rod at the other end pushes the roller, thereby pushing the star-point plate to move and achieve tensioning.
[0037] In a preferred embodiment of the present invention, the contact structure of the adjusting star point plate is changed from the traditional direct contact with the top rod to contact with a rotatable roller, which has a small contact stress and is not easy to damage the star point plate.
[0038] In a preferred embodiment of the present invention, a roller contact groove is provided on the periphery of the star point plate mounting seat, so that the roller is not easy to slip off the star point plate seat during the process of adjusting the position of the star point plate.
[0039] In a preferred embodiment of the present invention, the spring of the spring push rod can be installed by first installing the spring push rod into the reserved hole of the front end cover, and then installing the spring from the rear, and tightening it with the rear end spring cover to facilitate the installation of the spring.
[0040] In a preferred embodiment of the present invention, a protrusion is provided between the spring push rod and the rear end spring cover, so as to ensure that the spring will not deflect during the compression and relaxation process.
[0041] The star point plate mounting assembly (20) comprises a star point plate mounting seat (21) and a pressing ring (22);
[0042] The star point plate (70) is pressed onto the star point plate mounting seat (21) by the pressing ring (22).
[0043] The locking top screw (90) is mounted and fixed on the rear end mounting cover (40), and the number of the locking top screws (90) is no less than four.
[0044] It is used to lock the position of the star point plate 70 after the position of the star point plate is adjusted.
[0045] The included angle between the X-direction and the Y-direction of the propulsion assembly (10) is 90°.
[0046] In a preferred embodiment of the present invention, the star point plate position adjustment mechanism has two locations on a circle with an included angle of 90°, and can adjust the star point plate in the x and y directions simultaneously without interfering with each other.
[0047] The advancing screw 11 of the advancing assembly 10 is turned, thereby advancing the roller 14 to displace the star point plate assembly 20, and at the same time advancing the spring advancing rod 53 in the reset spring assembly 50, and making its compression spring 54 provide a reverse thrust, and finally making the roller 14 and the roller 51 clamp the star point plate assembly 20, so as to realize the axial advancement of the star point plate by the star point plate adjusting mechanism 100;
[0048] The propulsion screw 11 of the propulsion assembly 10 is turned in the opposite direction, thereby pulling the roller 14 and resetting the spring propulsion rod 53 in the spring assembly 50. Under the action of the spring 54, a thrust is provided to displace the star point plate assembly 20, and the roller 14 and the roller 51 can clamp the star point plate assembly 20, thereby realizing the axial tightening action of the star point plate of the star point plate adjustment mechanism 100.
[0049] When the propulsion assembly 10 in the X and Y directions rotates or rotates in the opposite direction, the star point plate can be pushed or tightened in the X and Y directions. When the hexagonal wrench is used to tighten the top screw, the position of the star point plate can be locked.
[0050] The rear part of the roller mounting seat 13 is provided with a groove. Figure 1It can be seen that the groove is used to connect with the advancing screw 11. When the advancing screw 11 rotates and moves up and down, it will push the roller mounting seat 13 to move up and down linearly, and the roller mounting seat 13 drives the roller 14 to complete the advancing action.
[0051] A groove is provided at the rear of the roller mounting seat 51, and the groove is used to connect with the spring push rod 53. When the spring 54 pushes the spring push rod 53, it will push the roller mounting seat 51 to move up and down linearly, and the roller mounting seat 51 drives the roller 52 to complete the clamping of the star point plate and the reset action.
[0052] The propulsion assembly 10 cooperates with the spring return assembly 50 to complete the position adjustment of the star point plate in a certain axial direction.
[0053] The operation of locking the top screw 90 is completed on the rear end mounting cover 40, and the locking execution action is completed at the other end. This separate design structure enables the star point plate adjustment mechanism 100 to achieve long-distance locking through a longer push screw 11.
