Floating zoom mechanical structure

Abstract

The invention discloses a floating zoom mechanical structure, belongs to the technical field of floating focusing and solves problems that adjustment of imaging by a traditional structure lens can only depend on naked eye observation for judgment, or simulation is performed through software, and movement precision cannot be realized. The structure is technically characterized in that the structurecomprises a machine body, a gear sleeve, a cam cylinder and a limiting cylinder, wherein the gear sleeve is arranged on a left side of the machine body, the cam cylinder is arranged on a right side of the gear sleeve, the limiting cylinder is arranged on a right side of the cam cylinder, the gear sleeve and the cam cylinder are in buckled connection, the cam cylinder and the limiting cylinder arein buckled connection, and a working cavity is formed among the gear sleeve, the cam cylinder and the limiting cylinder. The structure is advantaged in that the lens is simple, flexible, low in cost,convenient to assemble and disassemble and small in size, has the anti-vibration effect, is suitable for different use environments, has better reliability and stability than a traditional lens structure, and has more advantages.

Description

technical field [0001] The invention relates to the technical field of floating focus, in particular to a floating zoom mechanical structure. Background technique [0002] With the widespread application of lenses in industrial automation, intelligent transportation, machine vision and other fields, the requirements for lens imaging and focusing stability are getting higher and higher. The floating zoom structure cooperates with stepping motors through gears and adopts subdivision technology. The one-step movement distance is accurate to 0.01mm, which can realize the perfect fit of optics and structure, satisfy various use environments, and accurately focus at various working distances. [0003] Generally, the design of the lens has the best aberration correction at the common focusing distance, but it may appear the aberration at the shortest shooting distance. The floating focus system can move a whole group of lenses according to the length of the lens extension. , can i...
