Secondary mirror supporting mechanism capable of quick adjusting

Abstract

A secondary mirror supporting mechanism capable of quick adjusting belongs to the field of secondary mirror supporting mechanisms of electro-optic theodolites, and comprises a secondary mirror barrel, a plurality of first bolts, a secondary mirror seat, a plurality of second bolts, a plurality of secondary mirror pressing blocks, a plurality of third bolts, a plurality of sliding wedge blocks, a plurality of adjusting bolt seats, a plurality of fourth bolts, a plurality of adjusting bolts, a plurality of fixed wedge blocks, and a connecting cylinder, wherein the secondary mirror seat comprises a secondary mirror seat body, a secondary mirror seat boss, and a secondary mirror seat counter bore; the secondary mirror barrel comprises a secondary mirror barrel body, a secondary mirror barrel three-flanged flange, a three-flanged flange center hole, a secondary mirror barrel ring-shaped boss, and a secondary mirror barrel flange; each sliding wedge block comprises a sliding wedge block body, a sliding wedge block round hole, and a sliding wedge block slotted hole; each fixed wedge block comprises a fixed wedge block body and a fixed wedge block round hole; the connecting cylinder comprises a connecting cylinder body, a connecting cylinder flange, and a clamping groove. According to the invention, the optical precision adjusting process can be finished without detaching the secondary mirror repeatedly or repairing a secondary mirror adjusting cushion; the adjusting process of the secondary mirror is simple and accurate, and the adjusting efficiency can be adjusted greatly.

Description

technical field [0001] The invention belongs to the field of supporting mechanisms for secondary mirrors of photoelectric theodolites, and in particular relates to a supporting mechanism for secondary mirrors that can be quickly assembled and adjusted. Background technique [0002] As the key component of the main optical system of the photoelectric theodolite, the secondary mirror is mainly used to form a Cassegrain optical system with the primary mirror, reflect the light passing through the primary mirror, and make the light accurately enter the imaging lens group behind the secondary mirror, and finally irradiate On the target surface of the detector to achieve the purpose of imaging. With the rapid development of optical lens processing and inspection technology, the imaging quality of the Cassegrain optical system is constantly improving, and at the same time, the accuracy of the secondary mirror assembly is required to be higher and higher, and the time spent in the a...

Problems solved by technology

[0006] In order to solve the existing photoelectric theodolite secondary mirror support mechanism, the installation and adjustment process can only be completed by repeatedly disassembling the secondary mirror and repairing the secondary mirror adjustment pad. It is not easy to solve the technical problem of precision adjustment of this type of optical system. The present invention provides a secondary mirror support mechanism that can be quickly assembled and adjusted.
