Description

Technical Field

[0001] This utility model relates to the field of laser seeker zero-position error measurement and calibration technology, and in particular to a laser seeker zero-position error measurement and calibration device. Background Technology

[0002] A laser seeker is an optoelectronic detection device used in precision-guided weapons. It receives laser-coded signals reflected from the target, calculates the relative positional deviation between the missile and the target in real time, and guides missiles, bombs, or drones to hit the target.

[0003] In existing calibration devices, the product under test is usually placed and then measured and calibrated. This results in insufficient stability and makes the zero-point error measurement and calibration work prone to errors due to environmental influences, leading to calibration problems. In addition, while general measurements are usually performed in normal environments, in actual use, the device is often in a foggy environment, making it impossible to inspect the seeker in the current environment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laser seeker zero-position error measurement and calibration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laser seeker zero-position error measurement and calibration device includes a worktable and a product under test. A support platform is fixedly installed on the worktable, and the product under test is placed on the support platform. A light target substrate is fixedly installed on the worktable, and a laser sensor is fixedly installed on the worktable. Two mutually symmetrical stabilizing blocks are fixedly installed on the worktable, and a bidirectional screw is rotatably installed on each stabilizing block. Two mutually symmetrical clamping blocks are threadedly connected to the bidirectional screw. A rotary motor is fixedly installed on one of the stabilizing blocks, and the motor shaft of the rotary motor is fixedly installed on one end of the bidirectional screw. The two bidirectional screws are connected to each other through a belt drive assembly. A zero-position adjustment assembly is installed on the worktable.

[0007] Preferably, the zero-position adjustment assembly includes a lifting groove on the worktable, a zero-position plate slidably installed in the lifting groove, two mutually symmetrical racks fixedly installed on the zero-position plate, two mutually symmetrical rotating shafts rotatably installed on the worktable, each of the two rotating shafts being fixedly installed with a spur gear, the two spur gears meshing with the two racks respectively, and the two rotating shafts being connected to a bidirectional screw via a transmission assembly.

[0008] Preferably, the transmission assembly includes a second rotating shaft rotatably connected to the workbench. The second rotating shaft is connected to the bidirectional screw via a second belt transmission assembly. Two mutually symmetrical bevel gears are fixedly installed on the second rotating shaft. Two bevel gears are fixedly installed on each of the two rotating shafts. The two bevel gears mesh with the two bevel gears respectively.

[0009] Preferably, two symmetrical nozzles are fixedly installed on the workbench, a high-pressure pump is fixedly installed on the workbench, the two nozzles are connected to the high-pressure pump through two symmetrical connecting pipes, the two rotating shafts are respectively rotatably connected in the two connecting pipes, and a baffle plate is fixedly installed on each of the two rotating shafts.

[0010] Preferably, a protective layer is installed on the side wall of each of the two clamping blocks that are close to each other.

[0011] Preferably, two mutually symmetrical limiting blocks are fixedly installed on the zero-position plate.

[0012] 1. Compared with the prior art, the beneficial effects of this utility model are: by rotating the bidirectional screw through the rotary motor, and with the cooperation of the belt transmission assembly, the clamping block can stably clamp the product to be measured, thereby improving its stability. During the clamping process, the spur gear drives the rack to descend through the transmission assembly, which can lower the zero plate and facilitate subsequent measurement.

[0013] 2. By rotating shaft one, the baffle plate can be opened, thereby allowing water vapor to be sprayed out through the nozzle by the high-pressure pump, creating a mist environment to simulate the guiding environment of the product being tested. This allows staff to perform measurements and calibrations based on the current situation, meeting the staff's usage needs. Attached Figure Description

[0018] Reference Figures 1-3 A laser seeker zero-position error measurement and calibration device includes a worktable 1 and a product under test 2. A support platform 3 is fixedly installed on the worktable 1, and the product under test 2 is placed on the support platform 3. A light target substrate 4 is fixedly installed on the worktable 1. A laser sensor 10 is fixedly installed on the worktable 1. The laser sensor 10 is existing technology and can emit laser light and leave a light spot on the light target substrate 4. Two mutually symmetrical stabilizing blocks 5 are fixedly installed on the worktable 1. A bidirectional screw 6 is rotatably installed on the stabilizing block 5. The bidirectional screw 6 is existing technology and can make two objects connected to it move in different directions. Two mutually symmetrical clamping blocks 7 are threadedly connected to the bidirectional screw 6. A rotary motor 8 is fixedly installed on one of the stabilizing blocks 5. The motor shaft of the rotary motor 8 is fixedly installed on one end of the bidirectional screw 6. The two bidirectional screws 6 are connected by a belt drive assembly - 9, which consists of a belt body and two pulleys. A zero-position adjustment assembly is installed on the worktable 1.

[0019] The rotating motor 8 causes the bidirectional screw 6 to rotate, thereby bringing the two clamping blocks 7 closer together and stably clamping the product 2 being tested. With the cooperation of the belt drive assembly 9, the two bidirectional screws 6 can rotate simultaneously, thus ensuring that the product 2 being tested is clamped at both ends, further improving stability.

[0020] The zero-position adjustment assembly includes a lifting groove on the worktable 1, a zero-position plate 11 slidably installed in the lifting groove, two mutually symmetrical racks 12 fixedly installed on the zero-position plate 11, two mutually symmetrical rotating shafts 13 rotatably installed on the worktable 1, and spur gears 14 fixedly installed on each of the two rotating shafts 13. The two spur gears 14 mesh with the two racks 12 respectively, and the two rotating shafts 13 are connected to the bidirectional screw 6 through a transmission assembly.

[0021] The rotation of the rotating shaft 13 drives the spur gear 14 to rotate, which in turn drives the rack 12 to rise and fall, thereby driving the zero plate 11 to rise and fall. This is to cooperate with the measurement work. With the cooperation of the transmission components, when the zero plate 11 falls, the clamping block 7 clamps the product 2 to be measured. When the clamping block 7 is released, the zero plate 11 rises to prepare for the next round of measurement.

[0022] The transmission assembly includes a rotating shaft 15 rotatably connected to the worktable 1. The rotating shaft 15 is connected to the bidirectional screw 6 via a belt transmission assembly 16. Two mutually symmetrical bevel gears 17 are fixedly installed on the rotating shaft 15. Two bevel gears 18 are fixedly installed on both rotating shafts 13. The two bevel gears 17 mesh with the two bevel gears 18 respectively.

[0023] When a double-acting screw 6 rotates via belt drive assembly 16, it drives shaft 15 to rotate, which in turn causes bevel gear 17 on it to rotate, thereby driving meshing bevel gear 18 to rotate, which in turn drives shaft 13 to rotate.

[0024] Two symmetrical nozzles 19 are fixedly installed on the workbench 1. A high-pressure pump 20 is fixedly installed on the workbench 1. The two nozzles 19 and the high-pressure pump 20 are connected by two symmetrical connecting pipes 21. Two rotating shafts 13 are rotatably connected in the two connecting pipes 21 respectively. A baffle plate 22 is fixedly installed on each of the two rotating shafts 13.

[0025] With the rotation of the rotating shaft 13 and the cooperation of the high-pressure pump 20, the baffle plate 22 changes from closed to open, and water vapor is sprayed out through the nozzle 19 to form mist, providing an environment for measurement;

[0026] Protective layers are installed on the side walls of the two clamping blocks 7 that are close to each other. The protective layers can effectively protect the product 2 being tested and reduce the clamping friction damage it suffers. Two mutually symmetrical limiting blocks 23 are fixedly installed on the zero-position plate 11. The limiting blocks 23 can restrict the zero-position plate 11 and prevent it from falling.

[0027] In this invention, the working principle is as follows: The product to be tested 2 is placed on the support platform 3. The rotary motor 8 rotates the bidirectional screw 6, causing the two clamping blocks 7 to move closer together and stably clamp the product to be tested 2. Through the cooperation of the belt drive assembly 19, the two bidirectional screws 6 can rotate simultaneously, thus ensuring that the product to be tested 2 is clamped at both ends, further improving stability. Through the belt drive assembly 26, when one bidirectional screw 6 rotates, it drives the rotating shaft 25 to rotate, thereby causing the bevel gear 17 on it to rotate, which in turn drives the meshing bevel gear 28 to rotate, thus driving the rotating shaft 13 to rotate. Through the rotation of the rotating shaft 13, and with the cooperation of the high-pressure pump 20... When closed, the barrier plate 22 changes from closed to open, and water vapor is sprayed out through the nozzle 19 to form mist, providing an environment for measurement and driving the spur gear 14 to rotate. This drives the rack 12 to rise and fall, which in turn drives the zero-position plate 11 to rise and fall, thus coordinating with the measurement work. With the cooperation of the transmission components, when the zero-position plate 11 falls, the clamping block 7 clamps the product 2 to be measured. When the clamping block 7 is released, the zero-position plate 11 rises to prepare for the next round of measurement. After the zero-position plate 11 falls, the laser sensor 10 leaves a light spot on the light target substrate 4 to test the product 2. At the same time, the calibration work is adjusted through the existing calibration system.
