Abstract

The invention discloses an online dismounting and fast positioning and locking mechanism of a large-diameter lens, relates to a lens positioning and locking mechanism, and aims to solve the problem that the large-diameter wedged lens is quickly changed online to avoid use of large mechanical device for integrally detaching a large-diameter optical focusing and frequency converting system to lead to low efficiency. A top plate, a bottom plate and a side plate of a lens mobile frame body encircle the lens mobile frame body; an embedding piece of the lens mobile frame body is connected to the side plate of the lens mobile frame body; the top and bottom plates of the lens mobile frame body are provided with focusing lens guiding plates; a lens orientation angle is arranged at the edge of the wedged lens positioning frame; the large-diameter lens is fixedly arranged in the wedged lens positioning frame through a lens locking seat plate on a lens locking seat; lens assembly dismounting guiding bearing groups are arranged on the upper and lower side faces of the wedged lens positioning frame; the lens assembly dismounting guiding bearing groups are contacted with the mobile frame assembly; and the lens assembly is inserted into the mobile frame body assembly with the focusing lens guiding plate as a guide. The mechanism disclosed by the invention is used for online dismounting and fast positioning and locking of the large-diameter lens.

Description

technical field [0001] The invention relates to a large-diameter lens positioning and locking mechanism, in particular to a large-diameter lens fast positioning and locking mechanism for online disassembly and assembly. Background technique [0002] The large-aperture lens module (430mm×430mm) is the core component of the vacuum controllable high-throughput large-aperture optical focusing and frequency conversion system. The rapid online on-site replacement of the lens module makes the optical axis of the lens module point according to the requirements of the reference, ensuring the docking with the online reference and the consistency of the lens module after replacement. Due to the dense arrangement of optical components in the large-aperture optical focusing and frequency conversion system, the space for disassembly and maintenance is greatly limited, and the requirements for vacuum and cleanliness are high. The conversion system uses large-scale mechanical equipment to ...
