Abstract
Description
Technical Field
[0001] This utility model relates to imaging equipment, and more particularly to a precision optomechanical component made of titanium alloy. Background Technology
[0002] Optical-mechanical components are mechanical parts used to fix and adjust optical elements when building an optical system, such as: fixed support rods, connecting rods, adjustment frames, mounting plates, base plates, fixing sleeves, mounting seats, displacement adjustment stages, etc.
[0003] Components such as adjustment brackets, mounting plates, and mounting bases are usually complex curved structures, or have bends or chamfered edges, which increases the difficulty of the manufacturing process.
[0004] Building complex optomechanical systems requires numerous precision components, involves long optical paths, and necessitates multi-dimensional spatial construction. The completed system is heavy, and its numerous suspended structures lack sufficient strength and rigidity, impacting the system's stability and beam pointing stability. Optical systems require frequent disassembly, adjustment, and fixation. Existing components, made of stainless steel and aluminum alloy, have low hardness and poor wear resistance. Tightening screws and connecting rods easily scratches the surface, leading to uneven sliding adjustments. Frequent friction and sliding cause wear, affecting positioning and coaxial accuracy. Existing adjustment frames, mounting plates, mounting bases, and displacement adjustment stages are typically made of aluminum alloy, which has low specific strength and low surface hardness. Existing adjustment frames use stainless steel or carbon steel springs, which are prone to failure or plastic deformation after prolonged and frequent adjustments, leading to product malfunction.
