Embodiment
The utility model will be further described with reference to the accompanying drawings and examples.As depicted in figs. 1 and 2, this practicality
New be directed in micro objective installation process, because object lens or the requirement of Nosepiece installation accuracy are high, therefore is caused
Professional and technical personnel is needed repeatedly to be adjusted during installation, the problem of can just meeting use requirement and the technological improvement proposed.
Mainly by using integrally formed high-accuracy cast technique, coordinate special structure design, make above-mentioned object lens or thing
Mirror conversion seat can realize high accuracy positioning automatically, simplify a kind of new reference for installation seat of installation and debugging process.Such as Fig. 1 institutes
Show, a kind of micro objective reference for installation seat with self-locating function, by the positioning datum seat 2 being arranged in mounting bracket 1
Constitute, as shown in figure 3, major technique of the present utility model is improved to：Positioning datum seat 2 is to be arranged on microscope stand 1
The locating ring 3 of one opening U-shaped, its inner side is provided with standard circular arc, and the outer circular section of the circular arc and build-up member matches
Close, build-up member here is exactly object lens 8 or object lens conversion seat.Threaded locating hole 4 is provided with described locating ring 3, its
In be provided with fixing screws, build-up member can be held out against and be fixed on locating ring 3 by the fixing screws.Described department of assembly
On part at least with locating ring fixed part be cylinder gabarit, here usual object lens 8 or object lens conversion seat be all cylinder, therefore
As long as the outward appearance of this cylinder is engaged with the circular shape of locating ring 3.But if cut using square or polygon
The object lens 8 or Nosepiece in face, it is also desirable to ensure that at least part of is that section is circular, and this part circular is with positioning
The Inner arc part of ring is engaged, and is fixed in build-up member insertion locating ring 3 by positioning screw.And match with locating ring 3
The build-up member of conjunction is object lens 8 or object lens conversion seat, and its top is provided with the spacing ring 9 that circular fin is constituted, and this is spacing
The lower surface of ring 9 is adjacent to the upper surface of locating ring 3.In manufacturing process, the upper surface of locating ring 3 is level, and the following table of spacing ring 9
Face is equally level, after being adjacent to therebetween, just defines it is that the axis of object lens 8 or Nosepiece is environmentally friendly with positioning
Hold vertical.
As shown in Figure 3 and Figure 4, the circular arc on described locating ring 3 is 180 degree semi arch, here optimal selection semi arch
Primarily to circular arc stationkeeping ability is improved to greatest extent, because its bigger stationkeeping ability of arc angle is stronger, but more than 180
Degree can not then be installed, and in the beginning and end position of semi arch, at least one is provided with fixing screwed hole in addition, be provided with solid
Determine screw.Fixing screws are preferably provided on this position, the balance of fixed force can be ensured as far as possible, make the He of locating ring 3
That is fixed between build-up member is most stable.
As shown in Figure 3 and Figure 4, due to microscope in installation process, it is necessary to ensure optical axis with one heart, therefore for convenience into
As the installation of lens, while setting imaging len reference for installation seat 6 and lens barrel reference for installation seat 2.Set in mounting bracket 1
At least two positioning datums seat, one of them is lens barrel lens reference for installation seat or Nosepiece reference for installation seat 2,
Another is parallel to each other for imaging len reference for installation seat 6, and the positioning surface of above-mentioned two reference seat, and above-mentioned two are fixed
The center of circle of locating ring 3 in the reference seat of position is on the same line.It can be made first from microscope stand using this result
When, it is ensured that there is relatively accurate position between each part of microscope.Need exist for supplement in addition is in imaging len
Build-up member in reference for installation seat is the imaging len 7 of cylinder.Main design thought of the present utility model is using high-precision
The integrally casting processing of degree, for example：The modes such as cast aluminium, powder metallurgy, the precision of microscope stand is ensure that by being integrally formed,
Naturally the precision between each reference for installation seat is also ensure that, therefore two described reference seats are structure as a whole with support.And this
Reference for installation seat in utility model is to cooperate to protect by the external arc in the Inner arc and build-up member on locating ring 3
Installation accuracy is demonstrate,proved, therefore must possess the cylindrical structural that at least a portion is engaged with the circular arc of locating ring 3 on build-up member.
Consider that the positioning screw main function in positioning hole 4 is to hold out against build-up member in the Inner arc of locating ring, from
And reach pinpoint purpose.Therefore described positioning hole 4 is located at the non-arc position at the two ends of locating ring 3.So just can be with
Ensure that positioning screw can be produced and preferably hold out against effect.
Installation process of the present utility model is here by taking most common cylindrical object lens as an example.It is fixed that objective tube is placed into first
In the ring 3 of position, the spacing ring on objective tube top is located at the top of locating ring 3, under gravity on spacing ring lower surface and locating ring 3
Surface is adjacent to, and at this moment the positioning screw in the upper Positioning holes 4 of screwed in place ring 3 then holds out against objective tube in the Inner arc of locating ring 3,
Because the Inner arc of locating ring 3 and objective tube outer rim cooperate, therefore during holding out against, not only two arc surfaces are mutually pasted
Tightly, while two the circular also certain of circular arc overlap, this completes being accurately positioned therebetween, fixed spiral shell is now tightened
Nail can, it is necessary to explanation is due to that the positions of fixing screws is preferably disposed in the beginning and end of the upper half circular arc of locating ring 3,
Because this position fixing screws during holding out against, the component to any direction will not be produced, it is possible to prevente effectively from finally
Cause the problem of objective tube is offset in fixation procedure.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to the utility model
Limitation.In technological thought category of the present utility model, various modifications and modification, the ordinary skill of all this areas can occur
Retouching, modification or equivalent substitution that personnel are made as described above, belong to the scope that the utility model is protected.
