Two-dimensional adjusting mechanism of matrix type reflecting mirror group

Abstract

The invention discloses a two-dimensional adjusting mechanism of a matrix type reflecting mirror group. The two-dimensional adjusting mechanism comprises a support for installing and supporting the matrix type reflecting mirror group, a stepping motor I, a stepping motor II and a base; a rotary supporting component and the stepping motor II are fixedly installed on the upper end surface of the base; the upper side of the rotary supporting component is provided with an installation base; the power output shaft of the stepping motor II passes through the rotary supporting component and is connected with the bottom of the installation base; the stepping motor I is installed on the upper side of the installation base; the power output shaft of the stepping motor I is connected with one end of a transmission shaft; the middle portion of the transmission shaft is fixedly connected with the support through a flat key; and a bearing is arranged between the other end of the transmission shaft and the installation base. The two-dimensional adjusting mechanism of the invention has the advantages of reasonable design, simple structure, convenient operation, high reflection accuracy, wide application range, small size, light weight, convenient assembly and disassembly, easy transport and maintenance, low production cost and convenient popularization and utilization.

Description

technical field [0001] The invention relates to an angle adjustment mechanism, in particular to a two-dimensional adjustment mechanism for adjusting the angle of a matrix mirror group. Background technique [0002] In the optical system, it is often necessary to use a mirror to adjust the direction of light irradiation. In order to make the light incident on the mirror exit in the direction required by the system, it is necessary to adjust the normal direction of the mirror. At present, the adjustment mechanism for the normal direction of the mirror in the optical system includes an adjustment seat, two manual adjustment levers, a rigid support block, two elastic supports, and a mirror seat. The adjustment seat and the mirror seat are supported by two elastic supports. , the connection line between one manual adjustment rod and the rigid support block is perpendicular to the connection line between the other manual adjustment rod and the rigid support block. This adjustment...

AI Technical Summary

Problems solved by technology

This adjustment mechanism has the following defects: 1. The design is unreasonable and the structure is complicated; 2. The translation along the normal direction of the mirror surface is realized by the overall movement of the adjustment mechanism. This adjustment method cannot make the mirror strictly along the normal direction. movement, thus low adjustment accuracy
