Abstract

The invention relates to an installing and regulating device of an optical element, system or instrument, in particular to a double-precision optical regulation transmission device. The installing andregulating device comprises a coarse thread screw nut fixed on an optical regulating frame and a coarse thread screw rod connected through screw threads; the coarse thread screw rod is provided witha center hole in the axial direction; a ball head polish rod with a ball head at one end is arranged in the center hole; the center hole forms a cavity through expansion at the other end of the ball head; a press spring arranged outside the ball head polish rod in a penetrating way, a slide block connected with the ball head polish rod and a fine thread screw nut are sequentially arranged in the cavity; the fine thread screw nut is connected with a fine thread screw rod with one ball-shaped end through screw threads; the ball head of the fine thread screw rod is connected with the slide block;the other end is concentric with the regulation handle is fixed on the regulating handle; a position limiting post is fixedly arranged on the end surface of one end, near the regulating handle, of the coarse thread screw rod; a transmission post is fixedly arranged on the end surface, near the coarse thread screw rod, of the regulating handle. The installing and regulating device has the advantages that the coarse regulation and fine regulation double-precision regulation function can be realized; the higher regulation efficiency is improved; the light spot jumping in the regulation process is small; the light beams can be easily aligned.

Description

technical field

[0001] The invention relates to an installation and adjustment device of an optical element, system or instrument, in particular to a double-precision optical adjustment transmission device. Background technique

[0002] At present, the known precision optical adjustment mount (see attached figure 1 ) includes two functions of angle adjustment and translation adjustment, figure 1 Shown is a general-purpose solution for the two-dimensional angle adjustment frame, which mainly includes several parts shown in the figure. The fixed plate is generally fixed on the equipment through the installation hole. When adjusting one dimension rotation, by rotating one of the thread pairs, the thread The auxiliary nut is fixed on the fixed plate. The front end of the threaded auxiliary screw is a hemisphere. When the threaded auxiliary screw is rotated, the threaded auxiliary screw moves forward while rotating, pushing the movable plate to rotate around the supporting steel...
