Description
Technical field
The utility model relates to a kind of micro objective center inspection positioning components.
Background technique
Micro objective needs whether objective lens center reaches the precision index requirements of object lens after processing, general
Detection method is: positioning component being mounted in detection platform, then object lens are mounted on positioning component, then starting detection
Device detects object lens.The required precision of positioning component is high, and central shaft consistent with object lens central axis need to just can guarantee inspection
The accuracy of survey.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of accurate positionings conveniently, adjusts easy microscope
It examines and uses positioning component in object lens center.
In order to solve the above technical problems, the technology employed by the present utility model is a kind of micro objective center is examined
It tests and uses positioning component, the pedestal of optical path through-hole is equipped with including middle part, pedestal lower part is equipped with positioning seat, is equipped with inverted cone shape in positioning seat
Location hole, attachment base is equipped in location hole, attachment base top is in the inverted cone shape matched with location hole, and attachment base is pierced by positioning
Annular driving plate is equipped with by thread bush on the lower part of seat, is equipped with optical path through-hole in attachment base, attachment base lower part is embedded with installation
, stepped throughhole is equipped in mounting base, lower part is embedded with object lens interface rings, object lens interface rings in the stepped throughhole of mounting base
The screw being vertically arranged by least three is connected with the step surface in mounting base, and mounting base side is evenly equipped at least three ends
The WidFin screw that portion is in contact with object lens interface rings periphery.
The pedestal is equipped with the pin hole matched with positioning pin on monitor station.
As a preferred solution, the through-hole lower part of the pedestal is equipped with the positioning section that diameter is greater than top, the company
Joint chair top is equipped with the boss matched with positioning section.
The beneficial effects of the utility model are: due to the location hole for being equipped with inverted cone shape in positioning seat, the company of being equipped in location hole
Joint chair, attachment base top are in the inverted cone shape that matches with location hole, can guarantee well attachment base and eyepiece, object lens it is coaxial
Degree；It, can be right since mounting base side is evenly equipped with the WidFin screw that at least three ends are in contact with object lens interface rings periphery
The position of object lens interface rings is finely tuned, with the concentricity of the object lens interface rings and rotary shaft that ensure to install, to guarantee to detect
Required precision.
Since the pedestal is equipped with the pin hole matched with positioning pin on monitor station, the installation of pedestal can be made to position more
It is convenient.
Since the through-hole lower part of the pedestal is equipped with the positioning section that diameter is greater than top, the attachment base top is equipped with and determines
The boss that position section matches, so that the installation of attachment base and pedestal is more convenient.
