Description
Technical field
The invention belongs to ray machine integration techno logy fields, are related to a kind of Method of Adjustment of axial zoom mechanism, pass through this method
It can guarantee the concentricity moved between microscope group and fixed microscope group in axial direction zoom mechanism, while reducing processing cost, improve production
The quality of product.
Background technique
Axial zoom mechanism is a kind of optical zoom configuration of classics, by changing microscope group in the relative position of optical axis direction
To change focal length.It is very widely used due to configuration the space occupied small volume.
Axial zoom mechanism is that a kind of common optical zoom configuration, the superiority and inferiority of adjustment quality influence in optic-mechanical design
The performance of entire product.Due to the particularity of its structure, machine plus and assembling process in, it is difficult to ensure that movement microscope group and fixed mirror
The concentricity of group, directly affects the image quality of optical system.
The adjustment difficult point of axial zoom mechanism is how to guarantee that movement microscope group is same with fixed microscope group in movement travel
Axis degree.Fixed microscope group is mounted on the end of pedestal, as benchmark, fixes 4 polished rods, zoom microscope group and compensation microscope group on the base
It is fixed on the base by 2 polished rods respectively, it need to guarantee zoom microscope group and compensation microscope group when moving on polished rod, with fixed microscope group
Coaxially.Since what is guaranteed is concentricity after component assembly together, if improving machine to single part adds precision, cost pole
Height, and can not directly guarantee the precision after assembly；According to the mechanical processing technique method of Combined machining, then to the equipment of processing producer
It is more demanding.
Summary of the invention
Technical problems to be solved
In order to avoid the shortcomings of the prior art, the present invention proposes a kind of Method of Adjustment of axial zoom mechanism, pass through
The mode of replacement different size axle sleeve ensure that the concentricity relationship that microscope group and fixed microscope group are moved in axial zoom mechanism, in turn
It ensure that the quality of product.
Technical solution
A kind of Method of Adjustment of axial direction zoom mechanism, it is characterised in that steps are as follows:
Step 1: debugged product being placed on to the front end of internal focusing telescope 1, using internal focusing telescope 1 and fixed mirror
Group mounting hole 2 establishes 3 d space coordinate system, and the two is coaxial and as measuring basis；
Step 2: being moved forward and backward zoom microscope group 3, the spatial position of zoom microscope group 3 is measured by internal focusing telescope, is obtained
The coaxiality error of zoom microscope group 3 and measuring basis；
Step 3: replacing the axle sleeve 5 of different size, and held out against with axle sleeve fastening screw；Axle sleeve is held out against in axle sleeve mounting hole
Side drive zoom microscope group to generate displacement to change the position of polished rod 7；
If the needs of error display zoom microscope group 3 move up, 5 outer radial of lower part axle sleeve of supporting movement microscope group is reduced into specification
Direction change, will support zoom microscope group upper shaft sleeve outer radial increase specification direction change so that polished rod installation after generate to
On displacement；
If the needs of zoom microscope group 3 moves down, the lower part axle sleeve outer radial for supporting zoom microscope group is increased into specification direction and is changed,
The upper shaft sleeve outer radial for supporting zoom microscope group is reduced specification direction to change, then will generate downward displacement after polished rod installation；
Step 4: the deviation of zoom microscope group and fixed microscope group after replacement axle sleeve is measured using internal focusing telescope, if concentricity
It is unsatisfactory for requiring, then continues to replace axle sleeve, until meeting required precision；
Step 5: the screw of fixed hub being subjected to dispensing and is fixed, adjustment is completed.
Beneficial effect
A kind of Method of Adjustment of axial zoom mechanism proposed by the present invention, by the fixation microscope group mounting hole of debugged product with
Internal focusing telescope establishes 3 d space coordinate system, and the two is coaxial and as measuring basis；It is measured by internal focusing telescope
The spatial position of zoom microscope group obtains the coaxiality error of zoom microscope group and measuring basis；The axle sleeve of various outer diameter specification is matched,
So that the polished rod of axle sleeve support generates displacement, microdisplacement will be generated by the zoom microscope group that polished rod supports, passes through different axle sleeves
Concentricity between zoom microscope group and fixed microscope group is adjusted in place by combination.Can guarantee move microscope group be axially moved when with
The Method of Adjustment of fixed microscope group concentricity, the machine for reducing part add difficulty, reduce production cost, improve adjustment precision.
The advantages of the present invention are:, can by using a kind of Method of Adjustment of axial zoom mechanism of the present invention
With the concentricity relationship during adjustment of axial zoom mechanism, being greatly improved between movement microscope group and fixed microscope group, reduce
Processing cost.

Specific embodiment
Now in conjunction with embodiment, attached drawing, the invention will be further described:
Step 1: debugged product being placed on to the front end of internal focusing telescope 1, using internal focusing telescope 1 and fixed mirror
Group mounting hole 2 establishes 3 d space coordinate system, and the two is coaxial and as measuring basis；
Step 2: being moved forward and backward zoom microscope group 3, the spatial position of zoom microscope group 3 is measured by internal focusing telescope, is obtained
The coaxiality error of zoom microscope group 3 and measuring basis；
Step 3: replacing the axle sleeve 5 of different size, and held out against with axle sleeve fastening screw；Axle sleeve is held out against in axle sleeve mounting hole
Side drive zoom microscope group to generate displacement to change the position of polished rod 7；
If the needs of error display zoom microscope group 3 move up, it is smaller that the lower part axle sleeve for supporting zoom microscope group is changed to outer diameter
Specification, will support zoom microscope group upper shaft sleeve be changed to the biggish specification of outer diameter so that polished rod installation after generate it is micro to
On displacement；
If the needs of zoom microscope group 3 move down, the lower part axle sleeve of zoom microscope group will be supported to be changed to the biggish specification of outer diameter, it will
The upper shaft sleeve of support zoom microscope group is changed to the lesser specification of outer diameter, then will generate micro downward displacement after polished rod installation；
Step 4: the deviation of zoom microscope group and fixed microscope group after replacement axle sleeve is measured using internal focusing telescope, if concentricity
It is unsatisfactory for requiring, then continues to replace axle sleeve, until meeting required precision；
Step 5: the screw of fixed hub being subjected to dispensing and is fixed, adjustment is completed.
