Optical axis fine tuning device and fine tuning method thereof

Abstract

The invention relates to an optical axis fine tuning device and a fine tuning method thereof, and belongs to precision machinery. The device mainly comprises an overall height adjusting mechanism, a worm wheel and worm horizontal rotating mechanism and a pitch angle adjusting mechanism, wherein the worm wheel and worm horizontal rotating mechanism is arranged on the overall height adjusting mechanism; the overall height adjusting mechanism mainly comprises a base, a cylindrical guide rail, a linear moving rolling supporting piece, a middle support body and a height adjusting lead screw; the worm wheel and worm horizontal rotating mechanism mainly comprises a worm wheel shell, a worm wheel, a worm wheel vertical shaft, a worm and a rotating hand wheel; and the pitch angle adjusting mechanism is arranged on the worm wheel and worm horizontal rotating mechanism, and mainly comprises a worm wheel carrier plate, a carrier plate base, a carrier plate, a horizontal shaft, a pitch lead screw and a pitch lead screw hand wheel. The device has small overall volume and light weight; and the M6*0.25 superfine pitch thread precision lead screws are adopted in a transmission part, so the device has high adjusting and positioning precision and small repeatability errors.

Description

technical field [0001] The invention relates to an illumination angle adjustment device, in particular to an optical axis fine adjustment device applied to a laser illuminator, especially an optical axis fine adjustment device capable of high-precision adjustment of height, level and pitch and a fine adjustment method thereof.
