Detailed Implementation

[0018] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0019] This application discloses a laser ranging-based device for precise repair and positioning of automotive sheet metal dents.

[0020] Reference Figures 1-5 A laser ranging-based precision repair and positioning device for automotive sheet metal dents includes an annular fixed base 101, on which a fixing mechanism is provided. Two connecting brackets 102 are fixedly installed on the top of the annular fixed base 101, and the same annular plate 103 is fixedly installed on the two connecting brackets 102. Multiple arc-shaped plates 301 are rotatably installed on the outer side of the annular plate 103, and a guide mechanism is provided between the arc-shaped plates 301 and the annular plate 103. A horizontal plate 304 is fixedly installed on the bottom of the annular plate 103, and a vertical rod 401 is fixedly installed on the bottom of the horizontal plate 304. A ranging component for positioning the dent position and depth is provided at the bottom of the vertical rod 401. The ranging component includes a U-shaped plate 402, a rotating shaft 403, and a laser rangefinder 404. The U-shaped plate 402 is fixedly installed on the bottom end of the vertical rod 401. Rotating shafts 403 are rotatably installed on the inner walls of both sides of the U-shaped plate 402, and the same laser rangefinder 404 is fixedly installed at the ends of the two rotating shafts 403 that are close to each other.

[0021] In this embodiment, the fixing mechanism includes a threaded hole 201, a threaded rod 202, a handwheel 204, and a fixing suction cup 203. The threaded hole 201 is formed on the annular fixing seat 101. The threaded rod 202 is threadedly installed inside the threaded hole 201. The fixing suction cup 203 is fixedly installed at the bottom end of the threaded rod 202, and the handwheel 204 is fixedly installed at the top end of the threaded rod 202. By rotating the handwheel 204, the threaded rod 202 is driven to rotate. Under the action of the threaded hole 201, the threaded rod 202 rotates and moves, thereby driving the fixing suction cup 203 to move, thus fixing the fixing suction cup 203 to the uneven outer surface of the car, ensuring the stability of the device installation. This structural design allows the device to adapt to car sheet metal with different curvatures and surface conditions, significantly improving the versatility and installation reliability of the device.

[0022] In this embodiment, the guiding mechanism includes an annular guide groove 302 and an arc-shaped guide seat 303. The annular guide groove 302 is formed on the outer side of the annular plate 103, and the arc-shaped guide seat 303 is fixedly installed on one side of the arc-shaped plate 301 and slidably installed in the arc-shaped guide groove. The arc-shaped guide seat 303 slides in the annular guide groove 302, allowing the arc-shaped plate 301 to rotate around the annular plate 103, providing a basis for multi-angle measurement of the laser rangefinder 404. The cooperation structure of the annular guide groove 302 and the arc-shaped guide seat 303 not only ensures the smooth rotation of the arc-shaped plate 301, but also effectively prevents the arc-shaped plate 301 from derailing during rotation by limiting the guide seat through the guide groove.

[0023] In this embodiment, the bottom of the annular fixing plate is provided with multiple fixing grooves 501, and the horizontal plate 304 is provided with an insertion structure adapted to the fixing grooves 501. The insertion mechanism includes a threaded hole 502, a fixing screw 503, and a knob 504. The threaded hole 502 is located on the bottom of the horizontal plate 304, and the fixing screw 503 adapted to the fixing groove 501 is installed in the threaded hole 502. The knob 504 is fixedly installed at the bottom end of the fixing screw 503. This insertion mechanism not only achieves a firm connection between the horizontal plate 304 and the annular fixing plate, but also provides a stable locking force through the threaded engagement, effectively avoiding loosening caused by vibration during the measurement process.

[0024] In this embodiment, a housing 601 is fixedly installed on the front side of the U-shaped plate 402, and the end of the rotating shaft 403 away from the laser rangefinder 404 extends into the housing 601. Rotating shafts 603 are rotatably installed on the top and bottom inner walls of the housing 601, and the top end of the rotating shaft 603 extends above the housing 601 and is fixedly installed with a rotating plate 605. By operating the rotating plate 605, the rotating shaft 603 can be rotated, thereby adjusting the angle of the laser rangefinder 404.

[0025] In this embodiment, a worm gear 604 is fixedly mounted on the rotating shaft 603, and a worm wheel 602 is mounted on the rotating shaft 403, with the worm gear 604 meshing with the corresponding worm wheel 602. The meshing transmission between the worm gear 604 and the worm wheel 602 transmits the rotation of the rotating shaft 603 to the rotating shaft 403, achieving precise adjustment of the angle of the laser rangefinder 404. The worm gear 604 and worm wheel 602 transmission has a self-locking characteristic, automatically locking after the laser rangefinder 404 is adjusted to the target angle, ensuring the stability of the angle during measurement and preventing angle deviation caused by accidental contact from affecting measurement accuracy.

[0026] In this embodiment, a controller is installed on one side of the connecting frame 102. The controller has a display screen, and the laser rangefinder 404 is electrically connected to the controller. The laser rangefinder 404 transmits measurement data to the controller. After processing the data, the controller displays the location and depth information of the sheet metal dent on the display screen. The integrated design of the controller and the display screen enables maintenance personnel to obtain measurement data in real time and quickly analyze the dent through a visual interface, significantly improving the efficiency and accuracy of the repair work.

[0027] The working principle of this invention is as follows: The annular mounting base 101 is fixed to the car surface by the fixed suction cup 203. When the car surface is uneven, the handwheel 204 and the threaded rod 202 are rotated. Under the action of the threaded hole 201, the threaded rod 202 can rotate and move simultaneously. The movement of the threaded rod 202 can move the fixed suction cup 203, allowing for position adjustment. This achieves the purpose of fixing the fixed suction cup 203 to the uneven outer surface of the car. By rotating the rotating plate 605, the rotating plate 605 can rotate the rotating shaft 603 and the worm gear 604. The worm gear 604, through the worm wheel 602, can rotate the rotating shaft 403. The rotating shaft 403 can adjust the position of the laser rangefinder 40 according to the actual situation. The angle of the 4-axis can be adjusted to emit laser beams onto the automotive sheet metal surface from different angles. By rotating the knob 504 and the fixing screw 503, the fixing screw 503 can rotate and move simultaneously under the action of the threaded hole 502. The fixing screw 503 can be inserted into or disengaged from the corresponding fixing slot 501, which can achieve the purpose of fixing and releasing the horizontal plate 304 and the arc plate 301. By rotating the arc plate 301, the arc plate 301 can be rotated to the laser rangefinder 404. Through multiple laser rangefinder sensors measuring from different angles, the distance information of each point on the automotive sheet metal surface can be accurately obtained. After calculation and analysis by the data processing unit, the high-precision positioning of the sheet metal dent location and depth can be achieved, providing reliable data support for accurate repair of sheet metal dents.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
