Abstract
The present invention relates to a kind of contactless radome fairing centering debugging device and Method of Adjustment, including turntable, main frame, adjustment mechanism and photoelectric sensor；Fairing section is fixed on main frame, opening photoelectric sensor switchs and by sensor zero setting, under sensor instruction, by adjusting the amount of movement of rubber jackscrew at adjustment mechanism different location, so that the rectification centre of sphere is overlapped with the radome fairing pedestal centre of sphere.Originally the amesdial used is replaced with photoelectric sensor by the present invention, and the equipment adjustment precision is made to improve an order of magnitude, both can generate scratch using non-contacting method to avoid cowling surface.The precision of radome fairing centering both can be improved using the equipment, scratch can also have been generated to avoid cowling surface.The equipment has relatively broad application value in ray machine adjustment profession.
Description
Technical field
The invention belongs to ray machine integration techno logy field, it is related to a kind of contactless radome fairing centering debugging device and adjustment side
Method
Background technique
Generally there is fairing section on aerospace industry photoelectric detection equipment, with the continuous development of photoelectric technology,
The distance of required object observing is more and more remoter, and system whole resolution is higher and higher, and this requires to each point of optical system
The concentricity of component has higher requirement, while proposing very high required precision to the concentricity of fairing section.
Radome fairing centering resetting equipment working principle diagram is as shown in Figure 2.O in figure2For the radome fairing centre of gyration, O1For turntable
The centre of gyration, A are test point, and B, C are to pass through O1O2Diameter and circumference intersection point.With O1Make O for the centre of gyration1B returns back to O1B'
It sets, because the sum of triangle both sides are greater than third side then O1The position B' is to move up maximum position i.e. Δ l1, then have
l1-l0=Δ l1
Similarly O1C' is to move down maximum position i.e. Δ l2
l2-l0=Δ l2
Then have
l1-l2=Δ l1+Δl2
Work as O1O2It is overlapped or less than defined threshold i.e. it is believed that adjustment of feeling relieved is met the requirements, then has
Δl1With Δ l2Value can be asked by displacement sensor, need the adjustment amount to be
Radome fairing centering adjustment generally uses contact centering adjustment, measures radome fairing outer circle by using amesdial
Jerk value, then adjusting radome fairing is overlapped the radome fairing centre of sphere with the optical window pedestal centre of sphere with the relative position of optical window pedestal.
The amesdial that the prior art uses, measurement adjustment mode is contact, since dome material is relatively soft, is used
The method of contact is easy to generate scratch in cowling surface.
Summary of the invention
Technical problems to be solved
In order to avoid the shortcomings of the prior art, the present invention propose a kind of contactless radome fairing centering debugging device and
Method of Adjustment solves the problems, such as that radome fairing centering precision is low and cowling surface is easily caused to scratch.
Technical solution
A kind of contactless radome fairing centering debugging device, it is characterised in that including turntable 1, main frame 2, adjustment mechanism 3
With photoelectric sensor 4；Main frame 2 is plate structure, and the middle part of turntable 1 is stood on along turntable axis；Adjustment mechanism 3 is semicircle knot
Structure frame is connect with main frame 2, and multiple adjustment jackscrews 6 are uniformly provided on semicircular structure frame；Photoelectric sensor 4 is placed in tune
3 semicircular structure frame side of complete machine structure, induction end alignment are adjusted stream cover.
The multiple adjustment jackscrew 6 is three adjustment jackscrews, and three adjustment jackscrews are in 90 degree of angles, passes through three different positions
The jackscrew at the place of setting adjusts to complete the adjustment of components to be felt relieved.
A kind of Method of Adjustment using the contactless radome fairing centering debugging device, it is characterised in that steps are as follows:
Step 1: fairing section is fixed on main frame；
Step 2: opening photoelectric sensor switch and by sensor zero setting；
Step 3: when turntable, fairing section is rotated with it, and observes the numerical value of photoelectric sensor, when the number of sensor measurement
Word becomes larger, and jackscrew is tightened；When the number of sensor measurement becomes smaller, jackscrew is loosened；
Step 3 is repeated, until the variable quantity of photoelectric sensor is less than design requirement when turning around, adjustment is qualified.
Beneficial effect
A kind of contactless radome fairing centering debugging device and Method of Adjustment proposed by the present invention, including turntable, main frame,
Adjustment mechanism and photoelectric sensor；Fairing section is fixed on main frame, opens photoelectric sensor switch and by sensor
Zero setting, under sensor instruction, by adjusting the amount of movement of rubber jackscrew at adjustment mechanism different location so that the rectification centre of sphere with
The radome fairing pedestal centre of sphere is overlapped.Originally the amesdial used is replaced with photoelectric sensor by the present invention, makes the equipment adjustment precision
An order of magnitude is improved, both can generate scratch using non-contacting method to avoid cowling surface.Both may be used using the equipment
To improve the precision of radome fairing centering, scratch can also be generated to avoid cowling surface.The equipment has in ray machine adjustment profession
Relatively broad application value.
