From so as to light path reflects lens front-back respectively backtracking, and is imaged on a monitor；
Step 3：Lathe rotary shaft is rotated, two crosses are as movement locus on observation monitor and draw circle amount：
When two cross mesh pictures rotate picture Circular test：It is synchronous up and down, when left and right is contrary, represent that optical axis translation error is big, adjust
It is whole to translate microscope base, reduce picture circle amount, until draw Circular test changing；
When two cross mesh pictures rotate picture Circular test：Up and down conversely, when left and right is synchronous, representing that inclined light shaft error is big, adjust
It is whole to incline microscope base, until draw Circular test changing；
Step 4：Repeat step 3, until circle amount is drawn in both sides is reduced to design load.
Further preferred version, the method for quick adjustment lens axis during a kind of centering car, it is characterised in that：Before
Latter two interior focusing light pipe includes cross picture in same monitor simultaneously respectively to the lens front and rear surfaces imaging in microscope base
On, it is easy to contrast.
Beneficial effect
The fast adjustment method of lens axis is applicable to adjust lens light axis with rotation during the centering car that the present invention is provided
The conforming ray machine of rotating shaft is debug, simple efficient, practical, can realize the quick determination of optical axis position, greatly shortens centering
Car step adjustment time, operating efficiency is significantly improved.
The additional aspect and advantage of the present invention will be set forth in part in the description, and partly will become from the following description
Obtain substantially, or recognized by the practice of the present invention.
Description of the drawings
The above-mentioned and/or additional aspect and advantage of the present invention will become from the description with reference to accompanying drawings below to embodiment
It is substantially and easy to understand, wherein：

The cross picture shown on display when lens light axis are different from lathe rotary shaft relative position in Fig. 2 inventive embodiments
Image motion track figure.
The cross picture shown on display when lens light axis are different from lathe rotary shaft relative position in Fig. 3 inventive embodiments
Image motion track figure.
Specific embodiment
Embodiments of the invention are described below in detail, the embodiment is exemplary, it is intended to for explaining the present invention, and
It is not considered as limiting the invention.
The equipment that the fast adjustment method of lens axis is wherein used during the centering car that the present embodiment is provided has：Adjust in two
Burnt parallel light tube and its display device, two adjustment supports, a smooth turning lathes, the microscope base of a car to be felt relieved.Use
The structural representation of device is as shown in figure 1, ten shown on display during lens light axis different from lathe rotary shaft relative position
As image motion track figure as shown in Figures 2 and 3, the fast adjustment method of lens axis is comprised the following steps that word during centering car：
Step 1：Prepare two interior focusing auto-collimation collimators 1 and 2 with cross target source, light pipe 1,2 is put respectively
Put in the adjusting bracket of the rear and front end of lathe 3.As shown in Figure 1.Two light pipe relative positions are adjusted, makes what is fixed in adjusting bracket
Optical axis of the interior focusing auto-collimation collimator 1 with 2 it is parallel and by lathe rotary shaft 4 central through hole alignment.
Step 2：The microscope base 6 through thick centering is fixed by governor motion 5 in lathe rotary shaft 4.Now through thick
Centering, the lens light axis in microscope base 6 are substantially overlapped with microscope base periphery central shaft, according to the curvature half of former and later two minute surfaces of lens
Footpath, adjusts respectively the focusing distance of interior focusing autocollimator 1,2, makes the light difference Jing eyeglasses front-back reflection that light pipe sends
Neng Yuan roads return to light pipe, and while are imaged on the left and right sides on monitor 7.
Step 3：Rotary shaft 4 is rotated, two crosses in left and right are as movement locus on observation monitor 7 and draw circle amount：
If as shown in Fig. 2 two cross pictures rotate picture Circular test being：It is synchronous up and down, when left and right is contrary, i.e. left and right mirror image pair
