Description

Technical Field

[0001] This utility model relates to the field of laser guidance seeker testing technology, and in particular to a device for testing the tracking performance of a laser guidance seeker. Background Technology

[0002] Laser-guided seekers are a core component of precision-guided weapons, achieving target acquisition and tracking by receiving coded laser signals reflected from the target. The tracking performance of a laser-guided seeker is its core performance indicator, directly determining the weapon system's guidance accuracy and dynamic target engagement capability. Therefore, its tracking performance needs to be tested before use.

[0003] The laser-guided seeker consists of a hemispherical head and a cylindrical body, housing an optical lens, detector, signal processing unit, and control unit. The optical lens, including lenses and filters, focuses the reflected laser light and filters background light. The detector converts the optical signal into an electrical signal. The signal processing unit processes the electrical signal and extracts target position information. The control unit generates control commands for the guided weapon. The optical lens of the laser-guided seeker is mounted at the center of the hemispherical head.

[0004] In existing technologies, the tracking performance of laser seekers is generally tested manually. The tester holds a laser emitter and swings it within a certain angle range, ensuring the laser emitted by the emitter remains continuously aligned with the center of the seeker's head. A receiving device then receives control commands generated by the control unit. If the receiving device continuously receives control commands during the laser emitter's swing, the laser-guided seeker is considered to have acceptable tracking performance. If the receiving unit cannot receive or cannot continuously receive control commands, the laser-guided seeker is considered to have unacceptable tracking performance.

[0005] However, during manual testing, testers need to maintain a fixed swinging posture for a long time while being irradiated by laser, which can easily lead to beam deviation due to muscle fatigue. Furthermore, manual visual alignment is difficult to achieve millimeter-level positioning accuracy, which directly affects the accuracy of the seeker tracking performance test. Utility Model Content

Detailed Implementation

[0041] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0042] It should be noted that in the description of this utility model, "upper," "lower," "top," "bottom," and orientation or positional relationship are based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to 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.

[0043] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the apparatus for detecting the tracking performance of a laser-guided seeker in this embodiment includes:

[0044] Horizontal mounting plate 110.

[0045] The laser emitting swing assembly 200 includes a laser 210 for emitting a horizontal laser beam, a mounting base 220, an arc-shaped guide rail 230, a swing arm 240, and a slide table 250 that can slide along the arc-shaped guide rail 230.

[0046] The arc-shaped guide rail 230 is fixedly connected to the top of the horizontal mounting plate 110, and the slide table 250 is slidably mounted on the top of the arc-shaped guide rail 230; the swing rod 240 is horizontally set inside the arc-shaped guide rail 230 and one end is fixedly connected to the top of the slide table 250; the mounting base 220 is located above the end of the swing rod 240 that is fixedly connected to the top of the slide table 250, and the mounting base 220 is fixedly connected to the swing rod 240; the laser 210 is fixedly mounted on the top of the mounting base 220, and the emitting head of the laser 210 faces the center of the circle containing the arc-shaped guide rail 230.

[0047] Specifically, in this embodiment, the swing arm 240 is a strip plate.

[0048] The driving component 300 is used to drive the laser emitting swing component 200 to emit a detection laser beam towards the laser guidance seeker 700 under test. The detection laser beam is a laser beam that can be received by the optical lens of the laser guidance seeker 700 under test within a certain angle range, with the center of the head sphere of the laser guidance seeker 700 under test as the origin.

[0049] The drive assembly 300 is equipped with a drive motor 310, which is fixedly connected to the horizontal mounting plate 110. The other end of the swing arm 240 is located at the center of the circle of the arc-shaped guide rail 230 and is fixedly connected to the output shaft of the drive motor 310.

[0050] One end of the swing arm 240 is fixed perpendicularly to the output shaft of the drive motor 310. When the drive motor 310 is started, the swing arm 240 can swing around the output shaft of the drive motor 310. During the swinging process of the swing arm 240 around the output shaft of the drive motor 310, it can drive the slide table 250 to slide relative to the arc-shaped guide rail 230, thereby realizing the movement of the mounting base 220 along the arc of the arc-shaped guide rail 230.

[0051] The guide head fixing component 400 is used to fix the laser guidance guide head 700 under test.

[0052] Specifically, after the guide head fixing component 400 fixes the laser guidance head 700 under test, the axis of the laser guidance head 700 under test is aligned with the horizontal perpendicular line connecting the two ends of the arc-shaped guide rail 230, and the center of the head of the laser guidance head 700 under test is located on the output shaft axis of the drive motor 310, and the distance between it and the horizontal mounting plate 110 is equal to the distance from the center of the laser 210's emitting head to the horizontal mounting plate 110.

[0053] By using the guide head fixing component in this embodiment to fix the laser guidance seeker 700, it can be achieved that during the swinging process of the swing arm 240, the laser beam generated by the laser 210 is always aligned with the center position of the head of the laser guidance seeker 700 with qualified tracking performance, that is, aligned with the optical lens of the laser guidance seeker 700, so that the laser guidance seeker 700 continuously generates control commands.

[0054] The control box 500 is used to receive control commands generated by the control unit of the laser guidance seeker 700 and to determine whether the tracking performance of the laser guidance seeker 700 under test is qualified.

[0055] In this embodiment, the control box 500 is fixedly connected to the horizontal mounting plate 110. The control box 500 is electrically connected to the laser 210, the drive motor 310, and the laser guidance head 700 under test. It is used to supply power to the laser 210, the drive motor 310, and the laser guidance head 700 under test, and to realize communication between the laser guidance head 700 and the control box 500.

[0056] Specifically, the control box 500 can control the rotation of the drive motor 310 to control the rotation of the swing arm 240, that is, the rotation angle of the swing arm 240 relative to the output shaft of the drive motor 310 is controlled by the control box 500. In this embodiment, during the testing of the tracking performance of the laser guidance seeker 700, within a certain time range, if the control box 500 can continuously receive control commands sent by the laser guidance seeker 700 under test, then the tracking performance of the laser guidance seeker 700 under test is qualified; if the control box 500 cannot receive control commands sent by the laser guidance seeker 700 under test, or cannot continuously receive them, then the tracking performance of the laser guidance seeker 700 under test is unqualified.

[0057] The device for testing the tracking performance of a laser-guided seeker in this embodiment can achieve automated testing of the laser-guided seeker 700, with accurate and fast testing results.

[0058] In one embodiment, the drive assembly 300 is further provided with a motor mounting plate 320 and a coupling 330. The horizontal mounting plate 110 is provided with a first mounting hole, and the motor mounting plate 320 is provided with a second mounting hole. The axes of the first mounting hole and the second mounting hole coincide.

[0059] The drive motor 310 is located below the horizontal mounting plate 110, and the motor mounting plate 320 is fixedly mounted on the top of the horizontal mounting plate 110. One end of the output shaft of the drive motor 310 passes through the first mounting hole and is fixedly connected to the horizontal mounting plate 110. The coupling 330 is vertically inserted into the second mounting hole. One end of the coupling 330 is fixedly connected to the output shaft of the drive motor 310, and the other end is fixedly connected to the end of the rocker arm 240 located at the center of the circle containing the arc-shaped guide rail 230. The function of the motor mounting plate 320 is to fix the drive motor 310 to the horizontal mounting plate 110, and the function of the coupling 330 is to fix the output shaft of the drive motor 310 and the rocker arm 240.

[0060] In one embodiment, such as Figure 4 As shown, the guide head fixing component 400 is provided with a support block 410 and a fixing block 420. The support block 410 is vertically fixed to the top of the motor mounting plate 320, and the fixing block 420 is fixedly assembled above the support block 410.

[0061] The top of the support block 410 is horizontally provided with a semi-cylindrical cavity 421 for fixing the laser guidance head 700 under test. The axis of the semi-cylindrical cavity 421 is parallel to the horizontal perpendicular line connecting the two ends of the arc-shaped guide rail 230, and the distance between the top of the semi-cylindrical cavity 421 and the horizontal mounting plate 110 is equal to the distance from the center of the laser head to the horizontal mounting plate 110.

[0062] The semi-cylindrical cavity 421 can limit the position of the laser guidance seeker 700 and ensure that the laser guidance seeker 700 will not be displaced in the vertical direction during the detection process.

[0063] At least one limiting block 422 is fixedly connected inside the semi-cylindrical cavity 421 to limit the position of the center of the head of the laser guidance seeker 700 under test. The function of the limiting block 422 is to limit the position of the laser guidance seeker 700 in the axial direction of the semi-cylindrical cavity 421.

[0064] It should be noted that, for example Figure 1 The laser guidance seeker 700 of different shapes and sizes shown in the figure can have its hemispherical cylindrical cavity size adjusted adaptively, as long as the position of the center of the head sphere of the laser guidance seeker 700 conforms to the description in the above embodiments.

[0065] Specifically, in this embodiment, there are two support blocks 410. Another function of the motor mounting plate 320 is to assemble the fixing block 420 using the two support blocks 410.

[0066] In one embodiment, limit posts 231 are fixedly connected to the top of both ends of the arc-shaped guide rail 230. The angle between the line connecting the center of the limit post 231 and the center of the circle containing the arc-shaped guide rail 230 and the horizontal perpendicular line connecting the two ends of the arc-shaped guide rail 230 is 25° to 30°.

[0067] The function of the limit post 231 is to prevent the swing arm 240 from going out of control and the slide table 250 from sliding out of the arc-shaped guide rail 230.

[0068] In one embodiment, the device for detecting the tracking performance of the laser guidance seeker is further provided with an optoelectronic limiting component, which includes a light-blocking plate 610 and two optoelectronic limiting switches 600.

[0069] The light-blocking plate 610 is vertically fixed to the outermost middle of the swing arm 240 away from the guide head fixing part 400. The photoelectric limit switch 600 is fixedly connected to the horizontal mounting plate 110 and electrically connected to the drive motor 310. The two photoelectric limit switches 600 are located on a circle with the center of the circle containing the arc-shaped guide rail 230 as the center and the length from the light-blocking plate 610 to the center of the circle containing the arc-shaped guide rail 230 as the radius. The angle between the line connecting the center of the photoelectric limit switch 600 and the center of the circle containing the arc-shaped guide rail 230 and the horizontal perpendicular line connecting the two ends of the arc-shaped guide rail 230 is 20°.

[0070] The photoelectric limit switch 600 limits the swing range of the swing arm 240. When the swing angle of the swing arm 240, i.e., the angle between the center line of the swing arm 240 and the horizontal perpendicular bisector of the line connecting the two ends of the arc-shaped guide rail 230, is less than 20°, the swing arm 240 continues to swing. When the angle equals 20°, the photoelectric limit switch 600 is activated. At this time, it is considered that the laser emitting swing assembly 200 is in an abnormal state, and the photoelectric limit switch 600 sends a stop signal to the drive motor 310, controlling the drive motor 310 to stop rotating. Both the limit post 231 and the photoelectric limit switch 600 are safety protection structures.

[0071] In one embodiment, such as Figure 5 As shown, the mounting base 220 includes a base plate 225, baffles 221 vertically fixedly connected to the periphery of the base plate 225, a pressure plate 222, a handle 223, and a spring 224; the base plate 225 is fixedly connected to the top of the swing rod 240, and the pressure plate 222 is vertically slidably mounted above the base plate 225; the baffle 221 near the guide head fixing member 400 is provided with a third mounting hole, and the handle 223 passes through the third mounting hole and is fixedly connected to the pressure plate 222; the part of the handle 223 located between the pressure plate 222 and the baffle 221 near the guide head fixing member 400 is fitted with the spring 224; the laser 210 is clamped and fixed to the side of the pressure plate 222 away from the third mounting hole.

[0072] By pulling the handle 223 in conjunction with the spring 224, the position of the pressure plate 222 is controlled, so that the pressure plate 222 presses and fixes the laser 210 on the mounting base 220, thus preventing the laser 210 from shaking during the detection process.

[0073] In one embodiment, the device for testing the tracking performance of a laser-guided seeker further includes a bracket 100 and a junction box 120. A horizontal mounting plate 110 is fixedly mounted on the top of the bracket 100; the junction box 120 is embedded in the horizontal mounting plate 110; a control box 500 is fixedly mounted below the horizontal mounting plate 110; and the laser-guided seeker 700 is electrically connected to the control box 500 via the junction box 120. The junction box 120 facilitates the quick disassembly and connection of different laser-guided seekers 700 and control boxes 500 under test.

[0074] The working process of the device for testing the tracking performance of a laser-guided seeker in this embodiment is as follows: the laser-guided seeker 700 to be tested is assembled onto the seeker fixing component 400; the control box 500 is started to supply power to the laser 210, photoelectric limit switch 600, drive motor 310 and the laser-guided seeker 700 to be tested; the control program set inside the control box 500 controls the drive motor 310 to rotate back and forth within ±20°, thereby driving the swing arm 240 to swing. At this time, the laser 210 continuously emits a laser beam towards the center position of the head of the laser-guided seeker 700 to be tested; the control box 500 is connected to the laser-guided seeker 700 to be tested and continuously receives the control commands of the laser-guided seeker 700 to be tested and judges whether the tracking performance of the laser-guided seeker 700 to be tested is qualified according to the control commands.

[0075] The device used in this embodiment for testing the tracking performance of a laser-guided seeker can perform automated testing on the laser-guided seeker 700 under test. The entire testing process is free from laser beam deviation, and the test results are accurate and fast.

[0076] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
