Description
Technical Field
[0001] The utility model relates to the technical field of optical equipment, in particular to an automatic lifting platform for optical fine-tuning. Background Art
[0002] Most optical components used to form optical systems or related to optical instruments need to be stably installed before they can be used, such as prisms, acousto-optic modulators, electro-optic modulators and other optical components. During the debugging and experiment of optical devices, a lifting platform is usually required to make slight position adjustments to the optical components.
[0003] Most existing lifting platforms are adjusted manually. During the adjustment process, you need to keep your hands gentle and steady, avoid sudden force or rapid movement, and avoid touching other optical components. The adjustment process is relatively cumbersome. Sometimes the optical lifting platform is installed in a small space, and the operator may be restricted by space. When the hand reaches into the moving parts for adjustment, the line of sight is blocked, which makes it inconvenient to adjust the moving parts. For this reason, we designed an automatic lifting platform for optical fine-tuning to solve the above problems. Utility Model Content
[0004] In order to solve the above technical problems, an automatic lifting platform for optical fine-tuning is provided. This technical solution solves the problem that the existing lifting platforms proposed in the above background technology mostly adopt manual adjustment. During the adjustment process, the hands should be kept gentle and steady, and sudden force or rapid movement should be avoided, and other optical components should be avoided. The adjustment process is relatively cumbersome. Sometimes the optical lifting platform is installed in a small space environment, and the operator may be restricted by space. When the hand reaches into the moving parts for adjustment, the line of sight is blocked, making it inconvenient to adjust the moving parts.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] An automatic lifting platform for optical fine-tuning comprises a base, wherein the left and right sides of the upper end of the base are fixedly connected with brackets, the upper ends of the two brackets are fixedly connected with a top plate, a first bevel gear is rotatably connected at the center of the upper end of the base, a screw rod is fixedly connected to the end of the first bevel gear, the other end of the screw rod is rotatably connected to the lower end of the top plate, a lifting block is threadedly connected to the outer surface of the screw rod, connecting rods are fixedly connected at the four corners of the upper end of the lifting block, the other end of the connecting rod passes through the lower end of the top plate and is fixedly connected to the lifting platform plate, a mounting seat is fixedly connected to the rear part of the upper end of the base, a servo motor is fixedly installed on the upper end of the mounting seat, the output end of the servo motor is fixedly connected to a rotating shaft, and the other end of the rotating shaft is fixedly connected to a second bevel gear.
[0007] Preferably, the second bevel gear is meshed with the first bevel gear.
[0008] Preferably, two guide rods are fixedly connected to the inner sides of the two brackets between the base and the top plate, and guide blocks are slidably connected to the outer surfaces of the guide rods. The two guide blocks are fixedly connected to the left and right sides of the lifting block respectively.
[0009] Preferably, a protective plate is fixedly connected between the two brackets, and the protective plate is located between the second bevel gear and the lifting block.
[0010] Preferably, four evenly distributed mounting screw holes are provided on the upper end of the lifting platform.
[0011] Preferably, a laser rangefinder is fixedly mounted on the left side of the upper end of the lifting platform.
[0012] Preferably, the measuring end of the laser rangefinder is flush with the lower end of the lifting platform.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] This scheme proposes an automatic lifting platform for optical fine-tuning, in which the servo motor drives the rotating shaft and the second bevel gear to rotate, which can drive the first bevel gear and the lead screw to rotate. When the lead screw rotates, under the limiting action of the two guide blocks, the lifting block will slide along the outer surface of the lead screw, thereby driving the lifting platform plate to rise and fall through the connecting rod. Adjustment driven by the servo motor is smoother than manual adjustment, and the adjustment is also more convenient.
[0015] A laser rangefinder is provided in this solution. When the height of the lifting platform is adjusted, the laser rangefinder will measure the distance between the lifting platform and the top plate and feed back the measurement data to an external controller. The controller then sends a signal to the servo motor, and the height of the lifting platform is adjusted by the drive of the servo motor. Through layer-by-layer feedback and monitoring by the laser rangefinder, subtle adjustments can be made very accurately. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0021] Reference Figure 1 As shown, an automatic lifting platform for optical fine-tuning includes a base 1, and brackets 2 are fixedly connected to the left and right sides of the upper end of the base 1, and the upper ends of the two brackets 2 are fixedly connected to a top plate 3. A first bevel gear 4 is rotatably connected to the center of the upper end of the base 1, and a screw rod 5 is fixedly connected to the end of the first bevel gear 4. The other end of the screw rod 5 is rotatably connected to the lower end of the top plate 3, and a lifting block 6 is threadedly connected to the outer surface of the screw rod 5. Connecting rods 7 are fixedly connected to the four corners of the upper end of the lifting block 6, and the other end of the connecting rod 7 passes through the lower end of the top plate 3 and is fixedly connected to a lifting platform plate 8. Two guide rods 13 are fixedly connected to the inner side of the two brackets 2 between the base 1 and the top plate 3, and a guide block 14 is slidably connected to the outer surface of the guide rod 13. The two guide blocks 14 are respectively fixedly connected to the left and right sides of the lifting block 6, and the two guide blocks 14 are used to guide and limit the lifting block 6.
[0022] Furthermore, the screw rod 5 can be driven to rotate by rotating the first bevel gear 4. When the screw rod 5 rotates, due to the limiting effect of the two guide blocks 14, the lifting block 6 will slide along the surface of the screw rod 5, thereby driving the lifting platform 8 to rise or fall through the connecting rod 7.
[0023] Furthermore, a protective plate 15 is fixedly connected between the two brackets 2. The protective plate 15 is located between the second bevel gear 12 and the lifting block 6. The protective plate 15 is used to block the lifting block 6 to prevent the lifting block 6 from colliding with the second bevel gear 12 when descending.
[0024] Furthermore, four evenly distributed mounting screw holes 16 are provided at the upper end of the lifting platform 8 , and the optical instrument can be mounted on the upper end of the lifting platform 8 through the mounting screw holes 16 and bolts.
[0025] Reference Figure 1 and Figure 2 As shown, a mounting seat 9 is fixedly connected to the rear upper end of the base 1, a servo motor 10 is fixedly installed on the upper end of the mounting seat 9, a rotating shaft 11 is fixedly connected to the output end of the servo motor 10, a second bevel gear 12 is fixedly connected to the other end of the rotating shaft 11, the second bevel gear 12 is meshed with the first bevel gear 4, and the servo motor 10 can drive the rotating shaft 11 and the second bevel gear 12 to rotate. Since the second bevel gear 12 is meshed with the first bevel gear 4, the second bevel gear 12 will drive the first bevel gear 4 and the screw rod 5 to rotate synchronously when it rotates.
[0026] Furthermore, a laser rangefinder 17 is fixedly installed on the left side of the upper end of the lifting platform 8. The measuring end of the laser rangefinder 17 is flush with the lower end of the lifting platform 8. The laser rangefinder 17 can measure the distance between the lifting platform 8 and the top plate 3. When the height of the lifting platform 8 is adjusted, the laser rangefinder 17 feeds back the measurement data to an external controller, and the controller then sends a signal to the servo motor 10. The height of the lifting platform 8 is adjusted by the drive of the servo motor 10, thereby achieving precise control.
[0027] Working principle: When in use, first install the optical instrument to the upper end of the lifting platform 8 through the installation screw holes 16 and bolts. When the height of the lifting platform 8 needs to be adjusted, the servo motor 10 drives the rotating shaft 11 and the second bevel gear 12 to rotate. Since the second bevel gear 12 is engaged with the first bevel gear 4, the first bevel gear 4 will drive the screw rod 5 to rotate synchronously. Under the limit of the two guide blocks 14 and the drive of the screw rod 5, the lifting block 6 will slide along the surface of the screw rod 5. During the movement, the lifting block 6 will drive the lifting platform 8 to rise or fall through the connecting rod 7.
