Design of the structure of optical lens tubes and its flexible hinge
The design of the optical tube structure and its adjusting mechanism is completed through the analysis of the demand and installation of the receiving optical lens of the opto-mechanical system.The comprehensive charac-teristics of the designed structure are analyzed by theoretical calculation and finite element simulation.The results show that the receiving optical lens can meet the optical quality requirements by turning with self-centering with 6061 frames;Adopting the method of coping spacer to achieve±0.01 mm adjustment along the optical axis direc-tion,and using a flexible hinge made of TC4 material with a straight circular notch to achieve a deviation of±0.8 ° to meet the precision adjustment requirements;The institution has good optical and mechanical adjustment accura-cy and structural stability,meeting design requirements.
