Turning lens cone assembly based on rolling and pitching platform and assembling and adjusting method thereof

Abstract

The invention discloses a turning lens cone assembly based on a rolling and pitching platform and an assembling and adjusting method thereof. The assembling and adjusting methodcomprises the following steps of firstly, respectively assembling and adjusting a rolling and pitching frame platform part, a secondary lens cone assembly, a first reflector base assembly, a second reflector base assembly and a third reflector base assembly, assembling and adjusting all the assemblies, and then conducting overall joint debugging and convergence. The mechanical assembling and adjusting of the rolling and pitching frame platform part are carried out under the conditions that a rolling frame rotating shaft and a pitching frame rotating shaft can freely and easily rotate, clamping stagnation is avoided, and a frame is gapless, and the assembling and adjusting of the rolling and pitching frame platform part can be realized by assembling and adjusting the coaxiality and the gap of a frame bearing under the condition that the part machining precision meets the design precision; a rolling and pitching frame platform component is assembled and adjusted, and the purpose is to coincide an incident visual axis of a rolling optical system and a rotating shaft of a rolling frame; the center of the optical axis of the first right-angle reflex needs to coincide with the rotating shaft of the pitching frame; through second, third and fourth times of right-angle refraction and reflection, the center of the light is always on the intersecting plane of the pitch axis and the rotating shaft of the rolling frame; and the center of the optical axis is returned to the coincident direction of the rolling and pitching axis through four times of right-angle reflex.

Description

technical field [0001] The invention belongs to the field of precision mechanical design machinery, and specifically relates to a multi-dimensionally adjusted lens barrel assembly. Through mechanical structure adjustment, the multi-dimensional turning optical system achieves high imaging quality and positioning accuracy. Background technique [0002] In a complete optical-mechanical system, the design of the optical system and the design of the mechanical structure complement each other. A good optical system and the realization of the functions of optical components require the support and accuracy of the mechanical structure. Therefore, in the optical system, the mechanical structure Design played a crucial role. For the design of optomechanical systems, there are many factors that affect its final accuracy and performance, such as structural rationality, part accuracy, stiffness and strength, and assembly accuracy between parts. However, blindly using high-precision part...
