[0002] The focusing handwheel of a lidar system is a core component used to adjust the focal length of the transmitted and received beams. Its assembly accuracy directly affects the ranging accuracy, point cloud density, and overall performance of the lidar. The special assembly tooling for lidar focusing handwheels is a modular auxiliary assembly device specially designed for the special structure and assembly process requirements of lidar focusing handwheels. Through precise positioning, clamping, and calibration functions, this tooling ensures that the focusing handwheel meets the stringent standards of lidar for optical focusing accuracy, transmission smoothness, and environmental adaptability during the assembly process, while improving the efficiency and consistency of mass production.

[0003] A search revealed Chinese Patent Publication No. CN215373706U, which discloses a focusing handwheel and a sight, belonging to the field of sights. The focusing handwheel includes a handwheel body rotatably mounted on the sight. The sight includes a scope barrel and a positioning mechanism. The positioning mechanism includes a positioning groove, a positioning pin, and an elastic element. The positioning groove is formed on the scope barrel and opens towards the side of the handwheel body. The elastic element is fixed on the side of the handwheel body near the scope barrel. The positioning pin is fixed at the end of the elastic element away from the handwheel body. The end face of the positioning pin away from the elastic element is arc-shaped and can be engaged in the positioning groove. The inner wall of the positioning groove is arc-shaped.

[0038] 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.

[0039] Reference Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model provides a special assembly tool for a focusing handwheel, including a controller 1, which controls the rotation direction of a motor 401 and receives and processes real-time torque signals from a clamping mechanism 4 to perform torque closed-loop control. A connecting column 2 is fixedly connected to the top wall of the controller 1, and an installation groove 3 is provided on the top wall of the connecting column 2. A clamping mechanism 4 is provided at the top of the installation groove 3 for clamping the focusing handwheel. A fixing mechanism 5 is provided at the bottom of the controller 1 for fixing the controller 1.

[0040] The clamping mechanism 4 includes a motor 401, which is fixedly connected to the inner bottom wall of the mounting groove 3. A gear 402 is fixedly connected to the output end of the motor 401, and the motor 401 drives the gear 402 to rotate. A disc 403 is fixedly connected to the top wall of the connecting column 2. Multiple racks 404 are equidistantly meshed around the outer wall of the gear 402. Multiple circular grooves 406 are equidistantly opened on the outer wall of the disc 403. Multiple sliding rods 405 are fixedly connected to the inner wall of the circular grooves 406. The racks 404 are slidably connected to the sliding rods 405. The gear 402 drives the racks 404 to move on the sliding rods 405. The top of the sliding connecting column 2 is provided with a clamping assembly 407. Gear 402 is rotatably connected to the lower part of the inner wall of the disc 403. Slide rods 405 are equidistantly arranged inside the disc 403. The disc 403 provides a stable rotation fulcrum for gear 402, ensuring that gear 402 maintains stable rotation under the drive of motor 401, avoiding wobbling due to suspended rotation, thereby ensuring the smoothness of meshing transmission with rack 404. The equidistantly arranged slide rods 405 provide a radial sliding guide track for rack 404, ensuring the accuracy of radial movement of rack 404 under the drive of gear 402.

[0041] The clamping assembly 407 includes a slider 4071, which is slidably connected to the top wall of the rack 404. The top wall of the disc 403 is provided with multiple grooves 4072 at equal intervals. The grooves 4072 are slidably connected to the slider 4071. The top wall of the slider 4071 is equipped with a claw 4073. The rack 404 drives the slider 4071 and the claw 4073 to move synchronously towards the center in the grooves 4072, clamping the wheel 6 smoothly, firmly and without damage. The claw 4073 is made of soft rubber, which has elasticity and cushioning. When clamping the wheel 6 of the wind-measuring lidar, it can effectively prevent scratches, indentations or deformations that may be caused by hard materials, especially protecting the plating or precision threads on the surface of the wheel 6.

[0042] Specifically, the clamping mechanism 4 is used to clamp the focusing handwheel, and the fixing mechanism 5 is used to fix the controller 1. After starting the motor 401, the motor 401 drives the gear 402 to rotate, which in turn drives the rack 404 to slide along the slide bar 405. The movement of the rack 404 causes the slider 4071 and the jaw 4073 to move synchronously towards the center within the slide groove 4072. The jaw 4073 is made of soft rubber, which has elasticity and cushioning properties and higher friction parameters, ensuring that the wheel 6 is firmly fixed within the jaw 4073 during the rotation installation process, thus guaranteeing... The reliable assembly of the wind-measuring radar focusing mechanism ensures that the wheel 6 is clamped smoothly, firmly, and without damage. This process ensures that the final torque of each wheel 6 is precisely controlled within the preset range. Once the torque reaches the set value, the system will immediately send a signal to the controller 1 to stop the motor 401, thereby eliminating the inconsistency of manual operation. This not only guarantees the stability and reliability of the assembly quality of all radar units, but also adapts to the requirements of different models of wheel 6 or different production cycles, significantly improving the assembly efficiency and quality consistency of the crosswind radar production line.

[0043] Reference Figure 2 and Figure 5 The fixing mechanism 5 includes a base 501, which is located at the bottom of the controller 1. A threaded rod 502 is rotatably connected to the upper middle part of the outer wall of the base 501. A clamping block 503 is threadedly connected to the outer wall of the threaded rod 502. The bottom wall of the clamping block 503 has two sliding grooves 504 on both the front and rear sides. The top wall of the base 501 has two sliders 505 fixedly connected to both the front and rear sides. The sliding grooves 504 and the sliders 505 are slidably connected. The threaded rod 502 drives the sliding grooves 504 at the bottom of the clamping block 503 to slide on the sliders 505 at the top of the base 501. A drive assembly 506 is located at the bottom of the controller 1. The threaded rod 502 passes through the upper middle part of the left side of the outer wall of the base 501. The controller 1 is located on the right side of the outer wall of the clamping block 503. The threaded rod 502 passes through the base 501 to transmit the power of the gear 3 5063 to the threaded rod 502, causing the threaded rod 502 to rotate on the base 501. The controller 1 is located on the right side of the clamping block 503 to clamp the controller 1.

[0044] The drive assembly 506 includes a second motor 5061, which is fixedly connected to the inside left side of the base 501. A second gear 5062 is fixedly connected to the output end of the second motor 5061. The second motor 5061 drives the second gear 5062 to rotate. A third gear 5063 is meshed with the top wall of the second gear 5062. The second gear 5062 drives the third gear 5063 to rotate. The third gear 5063 is fixedly connected to the left end of the outer wall of the threaded rod 502. The third gear 5063 drives the threaded rod 502 to rotate.

[0045] Specifically, motor 2 5061 is started, which drives gear 2 5062 to rotate, thereby transmitting power to gear 3 5063, causing it to rotate. Gear 3 5063 drives threaded rod 502 to rotate, and threaded rod 502 causes the sliding groove 2 504 at the bottom of clamping block 503 to slide on slider 2 505 at the top of base 501. By controlling the forward and reverse rotation of motor 2 5061, clamping or releasing of clamping block 503 onto controller 1 is achieved. This device can flexibly adjust the position of the motor on base 501 according to the size and installation position of the wheel 6 used by the wind-measuring lidar, and ensures that the clamping center is precisely aligned with the installation axis after locking. This adjustability significantly improves the versatility of the tool, enabling it to adapt to the diverse needs of wind-measuring lidar product iteration or assembly of different models.

[0046] Reference Figure 1 and Figure 2 A wheel 6 is provided on the top of the connecting column 2. The wheel 6 is located on the adjacent side of the outer wall of multiple jaws 4073. The wheel 6 is located on the adjacent side of multiple jaws 4073 so that the jaws 4073 can clamp the wheel 6 at the same time to prevent the wheel 6 from shaking or shifting during assembly. A display screen 7 is provided on the left side of the outer wall of the controller 1. The display screen 7 is used to display the set torque. A button 8 is installed on the front side of the top wall of the display screen 7. The button 8 is used to control the motor 401 to start or stop.

[0047] Specifically, the wheel body 6 is located on one side adjacent to multiple jaws 4073 so that the jaws 4073 can clamp the wheel body 6 simultaneously to prevent the wheel body 6 from shaking or shifting during assembly. The display screen 7 is used to display the set torque, and the button 8 is used to control the motor 401 to start or stop.

[0048] Working principle: Start motor 401, which drives gear 402 to rotate. Gear 402 drives rack 404 to slide on slide bar 405. Rack 404 drives slider 4071 and pawl 4073 to move synchronously towards the center in slide groove 4072, clamping wheel 6 smoothly, firmly and without damage. This ensures that the final torque of each wheel 6 is precisely controlled within the preset range. When the torque reaches the set value, a signal is immediately sent to controller 1 to stop motor 401, eliminating inconsistencies in manual operation and ensuring stable and reliable assembly quality of all radar units. It can adapt to different models of wheel 6 or different production cycle requirements, significantly improving the assembly efficiency and quality consistency of the crosswind radar production line.

[0049] Motor 2 5061 is started, which drives gear 2 5062 to rotate. Gear 2 5062 drives gear 3 5063 to rotate, which in turn drives threaded rod 502 to rotate. Threaded rod 502 drives the sliding groove 2 504 at the bottom of clamping block 503 to slide on slider 2 505 at the top of base 501. By controlling the forward and reverse rotation of motor 2 5061, clamping or releasing controller 1 can be achieved. The position of the motor on base 501 can be flexibly adjusted according to the size and installation position of the wheel 6 used by different models of wind-measuring lidar. After locking, it ensures that the clamping center is precisely aligned with the installation axis. This adjustability greatly enhances the versatility of the tool, enabling it to adapt to the diverse needs of wind-measuring lidar product iteration or assembly of different models.
