Abstract

The invention provides a nanoscale micromotion mechanism and a measuring instrument, and belongs to the field of transmission structures. The nanoscale micromotion mechanism comprises a screw rod anda flexible metal frame, wherein the flexible metal frame comprises a first end block, a second end block and two flexible pieces; the two ends of the flexible pieces are separately connected with thefirst end block and the second end block; the two flexible pieces are arranged at intervals; the two flexible pieces are in threaded connection with the screw rod; and when the screw rod is rotated, the two flexible pieces are away from or close to each other. According to the nanoscale micromotion mechanism provided by the invention, the two flexible pieces are close to or away from each other through rotation of the screw rod, the two flexible pieces are deformed when being close to or away from each other, the first end block and the second end block are driven to move, and the first end block and the second block are close to or away from each other; and the structure is extremely simple, when the nanoscale micromotion mechanism is vibrated, the first end block and the second block canbe stably driven to be close to or away from each other through rotation of the screw rod, and the micromotion mechanism is high in precision, reliability and stability.

Description

technical field [0001] The invention relates to the field of transmission structures, in particular to a nanoscale micro-motion mechanism and a measuring instrument. Background technique [0002] The existing technology basically installs a micro-gear motor axially in the measurement direction to drive the screw to drive the movable measuring piece through the guide rail to generate horizontal displacement. The minimum adjustable displacement is not small enough. The "crawling" of the mechanical guide rail and the mechanical movement gap are due to physical principles. However, it is difficult to eliminate, it is prone to vibration, and the structure is complex. Due to the large mass of the fretting structure, the frequency response cannot be improved during observation and is easily disturbed by background vibration. The assembly stress between more parts will interfere with the strain to be measured. Contents of the invention [0003] The purpose of the present inventio...
