A differential heavy-duty fine-tuning mechanism

Abstract

The invention discloses a differential heavy-duty fine-tuning mechanism, which belongs to the field of ground integration technology for large-scale space optical remote sensors, and is used to solve the problem that the fine-threaded fine-tuning mechanism in the prior art cannot meet the ground height requirements for large-volume space optical remote sensors. The technical problem of the use requirements of precision and high-resolution adjustment, the present invention is provided with an adjustment stud; one end of the nut shell is threadedly connected with the adjustment stud, and the side wall of the nut shell away from the end of the adjustment stud is provided with a guide groove along the axis direction; The moving column is slidingly connected to the end of the nut shell away from the adjusting screw, and the side wall of the micro-moving column is fixedly connected with a guide pin, which is used to limit the degree of freedom of the micro-moving column in sliding connection with the guide groove around the axis of the nut shell; the micro-moving column is located at The end of the adjusting stud is threadedly connected with the adjusting stud; wherein, the adjusting stud is driven to rotate, and the adjusting stud can push the micro-movement column to displace along the axial direction of the nut shell. The invention has the beneficial effects of compact structure, large bearing capacity and simple operation.

Description

technical field [0001] The invention relates to the technical field of ground integration of large-scale space optical remote sensors, in particular to a differential heavy-duty fine-tuning mechanism. Background technique [0002] At present, with the increasing demand for ground reconnaissance and mapping, the volume and weight of space optical remote sensors have also doubled. For the ground high-precision and high-resolution adjustment of large-volume space optical remote Institutions have been unable to meet usage needs; [0003] Therefore, regarding the above problems, in order to meet the installation and adjustment needs of the above-mentioned large-scale heavy-duty space optical remote sensors, shorten the development cycle of space optical remote sensors, and ensure the integration quality of installation and adjustment, there is an urgent need for a compact structure, large carrying capacity, and simple operation. Dynamic heavy-duty fine-tuning mechanism. Conten...
