AI Technical Summary
The existing integrated lifting structure of optical platforms is difficult to achieve large-scale and rapid height adjustment and millimeter-level precision fine-tuning in local areas, which cannot meet the high-precision requirements of optical instrument calibration and precision assembly.
By employing a local lifting component combined with cylinder drive and gear transmission chain, the overall lifting and local fine adjustment of the optical platform can be achieved. The lifting block is moved precisely along the axial direction by a worm, turbine and lead screw, and the adjustment process is simplified by the movable sleeve structure.
It enables rapid height adjustment and precise local fine-tuning of the optical platform, reduces human error, and improves production and operation efficiency. It is suitable for optical instrument calibration and precision assembly scenarios.
