Specific implementation mode
A kind of airplane horizontal survey system of high-efficiency high-accuracy as shown in Figs. 1-3, including：
Device for dotting 1 is mounted on assembly jig 4, to 5 part of past body after 5 part of airframe is installed in place
On stamp mark, the device for dotting 1 include be fixedly mounted on installation foot 1a, the installation foot 1a on assembly jig 4 it is solid
Surely have to be provided on pedestal 1b, the pedestal 1b on the pointer 1c, the pedestal 1b that can be moved forward and backward and offer for before pointer 1c
The groove moved afterwards；
Laser tracker 2, to determine the space coordinate of mark；2 instrument reflection target of laser tracker is placed on marked position,
The laser that follower head is sent out is mapped in instrument reflection target returns to follower head again, so that it is determined that the space coordinate of each level point, swashs
Data L, α angle that optical tracker system 2 is measured by measurement point, the angles β determine the space spherical coordinates of measurement point；
Datum mark 3, to coordinate laser tracker 2 to complete the determination of marked position space coordinate, the measuring basis
There are four 3 settings of point, is arranged in the fuselage left and right sides and wing front and rear sides.
The utility model is described further with reference to specific embodiment.
Horizontal survey point is special by being arranged on assembly jig 4 generally in airplane design just given quantity and position
Door is used for the device for dotting 1 of horizontal point location, and making for level point is completed during component assembling.As shown in Figure 1.
The position of each level point is all distributed in leading portion, stage casing, vertical fin, empennage and the wing equipotential of fuselage under normal circumstances
It sets, this example is for measuring the measurement of wing degree of skewness.As can be known from Fig. 4, wing degree of skewness is by left two surveys in the left sides P1 and P2
Measure the difference on the left sides spacing L1 and the right sides P1 and the right right sides spacing L1 P2 of point, it is therefore desirable to know the correlation of 4 each point, it is specific to survey
Steps are as follows for amount：
1) aircraft is adjusted to horizontality and fixation according to aircaft configuration feature；
Level, supporting point when fixed are fixed and adjusted to aircraft by the indoor spaces that horizontal measurement need to select place open
Select aircraft at stile, it is ensured that undercarriage wheel is liftoff；
2）Suitable position is selected to fix four horizontal reference coordinate points on ground according to aircraft level point characteristic distributions；Root
According to the structure of aircaft configuration and supporting tool, selects the point of four distributions farther out to place and fix, coordinate is established with this four points
System；Measurement point light straight line is reachable in laser tracker 2 measurement request, one erect-position, and centre cannot have barrier；On aircraft
The big left and right of horizontal survey point is distributed, and since centre is blocked by fuselage, undercarriage etc., needs to turn station in measurement process, every time
Turn standing-meeting and form a coordinate system, turns station every time and carry out link conversion by four horizontal reference coordinate points, form a unification
Coordinate system；
3) laser locating apparatus is placed according to aircraft level point characteristic distributions, it is primary as possible to survey more level points, such as scheme
It shown in 4, reads the coordinate of four horizontal reference coordinate points respectively in erect-position 1, establishes coordinate system, then measure the seat on the left sides P1 and the left sides P2
Mark；
4) measuring device is placed on erect-position 2, reads the coordinate of four horizontal reference coordinate points respectively, establishes coordinate system,
Coordinate system of the system automatically with erect-position 1 is converted, and the coordinate on the right sides P1 and the right sides P2 is measured in erect-position 2；
5) the horizontal measurement point data measured by can be all recorded in computer, according to the requirement of numerical value, in computer
The left sides P1 and the left sides spacing L1, the right sides P1 and the right spacing L1 of P2 of right two measurement points of P2 are right respectively；
6）Determine whether wing degree of skewness meets the requirements according to the difference on the right sides a L1 left side-L1.
The measurement of wing degree of skewness can be completed by above step, it is primary similar, measure remaining various horizontal measurement parameter.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this
