Description

Detection work platform suitable for telescope disk

Technical field

The utility model is related to telescope finished product detection technical fields, and in particular to be suitable for the detection work of telescope disk Platform.

Background technology

Telescope is used to observe the details of distant objects.Since telescope imaging is more than object itself to eyes subtended angle To the intuitive subtended angle of eyes, thus by look in the distance sem observation when, the object of distant place seems to be moved closer to, and it is clear remote that people can see The details for locating object, expands the ability of the remote object of human eye observation.Telescope is the component part of many optical instruments, Mechanical performance and optical property directly affect the measurement accuracy of instrument.Generally in process of production, to telescope finished product detection Project mainly has：Optical axis partially, as tilt, magnifying power etc..It is mainly detected currently on the market using CZW telescopes comprehensive detector Telescope, the detector include body, perspective monitor station, projection screen, and wherein projection screen is located at the surface of perspective monitor station.This Although kind of instrument can detect the multinomial optical property of a variety of power telescopes, has many advantages, such as to integrate, is sensitive, it is being used There is also certain problems in the process：1, perspective monitor station is easy adhesive dust, influences accuracy of detection due to exposing in air And visual angle, it needs carefully cleaning every time before detection, is more troublesome.2, ambient light interference is big.

Utility model content

Technical problem to be solved in the utility model is to overcome the above technical problem, and it is an object of the present invention to provide suitable for looking in the distance The detection work platform of mirror eyeglass can reduce influence of the ambient light to telescope light transmission accuracy of detection, and excellent with dust-proof anti-gray Point.

The utility model is achieved through the following technical solutions：

Suitable for the detection work platform of telescope disk, including perspective monitor station, projector, the perspective monitor station, which is located at, to be thrown The underface of shadow device is opened there are one step groove in the upper surface of perspective monitor station, is opened on the bottom surface of step groove there are one groove, Bottom is that light path detects glass platform in the groove, further includes elastic black-out cloth, the edge and step groove of the elasticity black-out cloth Surrounding side wall fix, elastic black-out cloth surface also open there are one test place mouth, it is described test place mouth edge wrap Elastic rope simultaneously surrounds contractile annular ring；Eyepiece chopping mechanism there are one being also provided in the lower surface of projector.

For the above technical problem, the utility model is improved existing detection work platform, first in perspective monitor station Groove is opened up, light path in the prior art detection glass platform is mounted on the inner bottom surface of groove, and elastic black-out cloth is set, only A test is reserved on elastic black-out cloth and places mouth, and test placement mouth is rolled into a contractile ring by stretch cord Shape circle.When usually workbench is not used, elastic black-out cloth can be pullled by operating stretch cord so that mouth is placed in entire test Bore constantly reduces, final to collapse, with this so that forming one between groove and elastic black-out cloth with light path detection glass platform A closed cavity can avoid external world's dust pollution light path and detect glass platform, can solve to have an X-rayed monitor station in the prior art due to sudden and violent Dew in air, is easy adhesive dust, influences accuracy of detection and visual angle, needs carefully cleaning every time before detection, is more troublesome The problem of.

Secondly, it is also provided in the lower surface of projector and test is put when testing telescope there are one eyepiece chopping mechanism Mouth opening is set, telescope objective end to be detected is placed on light path detection glass platform, is then tightened stretch cord so that survey Examination places mouth and is just close to lens cone for telescope, prevents external environmental light from placing mouth from test and enters, then pulls down eyepiece shading machine The eyepiece end of telescope is blocked, is prevented in ambient light flat fire to eyepiece, it is saturating to telescope to greatly reduce ambient light in this way by structure The influence of light detection precision is conducive to improve measuring accuracy.

Preferably, the eyepiece chopping mechanism includes cone, is opened on the bottom surface of projector there are one sense channel, Sense channel inner wall is provided with sliding slot, and the cone is mutually matched with sense channel, and sliding block is provided on shading drum outer wall, The sliding block is mutually matched with sliding slot and can detect the axial movement in channel.It is the concrete structure of eyepiece shading mirror, shading above Cylinder can be moved up and down along sense channel.When in use, cone drop-down is covered into telescope ocular.

It is both provided with one layer of extinction film on the madial wall and cone inner wall of the groove.Madial wall in groove and shading One layer of extinction film is respectively set on cylinder inner wall, can effectively reduce the reflectance of its wall surface, further decrease ambient light to looking in the distance The influence of mirror test.

Preferably, the extinction film is black cotton.Black cotton surface is coarse, and photo absorption performance is strong, and reflective function is poor, and Material is easy to get, and inexpensively, is particularly suitable for using as extinction film.

The thickness of the elasticity black-out cloth is 1.5 ~ 3mm.Since elastic black-out cloth needs to stretch, its knitting density after stretching It can reduce, it is advantageous to be arranged the thickness of elastic black-out cloth in 1.5 ~ 3mm, can both maintain certain stretching density, while Laborious problem when can avoid pulling.

The utility model compared with prior art, has the following advantages and advantages：

1, the utility model is suitable for the detection work platform of telescope disk, and the groove and bullet of glass platform will be detected with light path Property black-out cloth between formed a closed cavity, can avoid the external world dust pollution light path detect glass platform, the prior art can be solved Middle perspective monitor station in air, is easy adhesive dust, influences accuracy of detection and visual angle due to exposure, is needed every time before detection Carefully cleaning, the problem of being more troublesome；

2, the utility model is suitable for the detection work platform of telescope disk, using eyepiece chopping mechanism and elastic black-out cloth, Influence of the ambient light to telescope light transmission accuracy of detection can be also reduced, is conducive to improve measuring accuracy.
