Description

Technical Field

[0001] This utility model relates to the field of laser rangefinder positioning technology, specifically an automatic positioning device for laser rangefinder calibration. Background Technology

[0002] A laser rangefinder is an instrument that accurately measures the distance to a target by modulating a laser with a specific parameter. A pulsed laser rangefinder emits a short, pulsed laser beam towards the target. A photoelectric element receives the reflected laser beam, and a timer measures the time from emission to reception to calculate the distance from the rangefinder to the target.

[0003] Traditional laser rangefinders require manual adjustment of the zero point during calibration. The rangefinder is also prone to tilting during use. Uneven placement of the rangefinder can lead to excessive measurement errors. This requires users to spend a lot of time and effort to complete the adjustment, increasing the positioning time of the laser rangefinder. The adjustment process involves many steps, is time-consuming, inefficient, and does not guarantee the accuracy of the adjustment.

[0004] Therefore, there is a need to provide an automatic positioning device for laser rangefinder calibration. Utility Model Content

[0005] The purpose of this invention is to provide an automatic positioning device for laser rangefinder calibration, so as to solve the problems of long positioning time, many adjustment steps, low adjustment efficiency and low adjustment accuracy of the traditional adjustment method mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic positioning device for laser rangefinder calibration, comprising a mounting component and a protective frame. A vertical adjustment mechanism is fixedly mounted on the side of the protective frame, and a horizontal adjustment mechanism is provided on the side of the vertical adjustment mechanism. The vertical adjustment mechanism includes a mounting plate, the side of which is fixedly connected to the side of the protective frame. A fixing block is fixedly mounted on the side of the mounting plate, and a first servo motor is fixedly mounted on the side of the fixing block. A first threaded rod is fixedly mounted on the top surface of the transmission rod of the first servo motor. A connecting component is fixedly mounted on the side of the mounting plate. The inner wall of the connecting component is rotatably connected to the side of the first threaded rod through a bearing. A first threaded sleeve is threadedly mounted on the side of the first threaded rod, and a first slider is fixedly mounted on the side of the first threaded sleeve.

[0007] Preferably, the lateral adjustment mechanism includes a fixing member, the side of which is fixedly connected to the side of the first slider, a second servo motor is fixedly mounted on the side of the fixing member, and a second threaded rod is fixedly mounted on the end face of the transmission rod of the second servo motor.

[0008] Preferably, a second threaded sleeve is threadedly installed on the side of the second threaded rod, and a second slider is fixedly installed on the side of the second threaded sleeve.

[0009] Preferably, a connecting block is fixedly installed on the side of the first slider, and a guide rail is fixedly installed on the side of the connecting block.

[0010] Preferably, a through hole is fixedly opened on the side of the second slider, and a sliding sleeve is fixedly installed on the inner wall of the through hole. The inner wall of the sliding sleeve is slidably connected to the side of the guide rail, and a laser emitter is fixedly installed on the side of the second slider.

[0011] Preferably, a bearing sleeve is fixedly installed on the side of the second threaded rod, and a mounting seat is fixedly installed on the side of the bearing sleeve, with the side of the mounting seat being fixedly connected to the end face of the guide rail.

[0012] Preferably, the mounting component has a reinforcing rib fixedly installed on its side, a base plate fixedly installed on its side, a fixing lug fixedly installed on its side, a threaded hole fixedly opened on the side of the fixing lug, a fastening bolt threaded on the inner wall of the threaded hole, the side of the base plate fixedly connected to the side of the protective frame, and a heat dissipation hole fixedly opened on the side of the protective frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This automatic positioning device for laser rangefinder calibration, when the device needs to be zeroed, uses a first servo motor to drive a first threaded rod to rotate, which in turn cooperates with a first threaded sleeve to drive a first slider to slide along the direction of the first threaded rod, thereby driving the laser emitter to adjust its vertical position; further, a second servo motor is activated to drive a second threaded rod to rotate, which in turn cooperates with a second threaded sleeve to drive a second slider to move along the guide rail, driving the laser emitter mounted on the side of the second slider to adjust its horizontal position, thus completing the laser emitter's position adjustment operation. This reduces the steps required for traditional manual adjustment, thereby improving the device's adjustment speed. The motor can more accurately control the adjustment distance, improving the device's adjustment accuracy.

[0015] 2) The automatic positioning device for laser rangefinder calibration, by installing fixing ears and fastening bolts, can effectively improve the stability of the connection between the device and the measuring equipment, thereby improving the measurement accuracy of the device. The first servo motor drives the first threaded rod to rotate, and the second servo motor drives the second threaded rod to rotate. The interaction between the first threaded sleeve and the second threaded sleeve improves the adjustment speed and accuracy of the device, further enhancing the practicality of the device and the precision of laser emitter adjustment.

[0023] Example 1

[0024] Combination Figures 1-5An automatic positioning device for laser rangefinder calibration includes a mounting component 1 and a protective frame 6.

The vertical adjustment mechanism 7 includes a mounting plate 701, the side of the mounting plate 701 is fixedly connected to the side of the protective frame 6, a fixing block 702 is fixedly mounted on the side of the mounting plate 701, a first servo motor 703 is fixedly mounted on the side of the fixing block 702, a first threaded rod 704 is fixedly mounted on the top surface of the transmission rod of the first servo motor 703, a connecting component 705 is fixedly mounted on the side of the mounting plate 701, the inner wall of the connecting component 705 is rotatably connected to the side of the first threaded rod 704 through a bearing, a first threaded sleeve 706 is threadedly mounted on the side of the first threaded rod 704, and a first slider 707 is fixedly mounted on the side of the first threaded sleeve 706.

[0025] Specifically, during use, the worker places the device at the measurement position for measurement. After the measurement is completed, the position of the laser emitter 810 needs to be zeroed. First, the first servo motor 703 is started. The first servo motor 703 drives the first threaded rod 704, which is fixedly installed on the end face of the transmission rod, to rotate. Then, through the thread, the threaded sleeve 706 drives the first slider 707 to move along the direction of the first threaded rod 704. This drives the horizontal adjustment mechanism 8 installed on the side of the first slider 707 to adjust its vertical position. After the adjustment is completed, the first servo motor 703 is turned off, and the position of the first slider 707 is temporarily fixed to prevent slippage. Moreover, the adjustment through the first servo motor 703 can more accurately improve the adjustment precision, thereby improving the positioning accuracy of the laser rangefinder.

[0026] Example 2

[0027] See Figures 1-5Furthermore, the lateral adjustment mechanism 8 includes a fixing member 801, the side of which is fixedly connected to the side of the first slider 707. A second servo motor 802 is fixedly mounted on the side of the fixing member 801. A second threaded rod 804 is fixedly mounted on the end face of the transmission rod of the second servo motor 802. A second threaded sleeve 808 is threadedly mounted on the side of the second threaded rod 804. A second slider 809 is fixedly mounted on the side of the second threaded sleeve 808. A connecting block 803 is fixedly mounted on the side of the first slider 707. A guide rail 807 is fixedly mounted on the side of the connecting block 803. A through hole is fixedly opened on the side of the second slider 809, and a sliding guide rail is fixedly mounted on the inner wall of the through hole. The inner wall of the sliding sleeve is slidably connected to the side of the guide rail 807. The laser emitter 810 is fixedly installed on the side of the second slider 809. The bearing sleeve 805 is fixedly installed on the side of the second threaded rod 804. The mounting seat 806 is fixedly installed on the side of the bearing sleeve 805. The side of the mounting seat 806 is fixedly connected to the end face of the guide rail 807. The side of the mounting component 1 is fixedly installed with a reinforcing rib 2. The side of the mounting component 1 is fixedly installed with a base plate 5. The side of the base plate 5 is fixedly installed with a fixing ear 3. The side of the fixing ear 3 is fixedly opened with a threaded hole. The inner wall of the threaded hole is threaded with a fastening bolt 4. The side of the base plate 5 is fixedly connected to the side of the protective frame 6. The side of the protective frame 6 is fixedly opened with a heat dissipation hole.

[0028] Specifically, when the laser emitter 810 needs to be adjusted laterally, the second servo motor 802 is activated. The second servo motor 802 drives the second threaded rod 804 to rotate, and cooperates with the second threaded sleeve 808 to drive the second slider 809 to move along the guide rail 807. Furthermore, when the second threaded rod 804 rotates, the mounting base 806 and bearing sleeve 805 adapt to the rotation of the second threaded rod 804, which can improve the stability of the second slider 809 during movement, so that the laser emitter 810 can be positioned more accurately. This drives the laser emitter 810 mounted on the side of the second slider 809 to adjust its lateral position, and cooperates with the vertical adjustment mechanism 7 to complete the adjustment of the laser emitter 810. In use, the reinforcing rib 2 installed on the side of the mounting part 1 improves the structural strength of the device, prevents shaking, improves the positioning accuracy, and the fixing ear 3 and fastening bolt 4 improve the ease of disassembly and assembly of the device.
