Description
Technical field
The present invention relates to the instrument that edge strip on a kind of big wing back rest of 737CL types aircraft repairs cutting positioning.This method is also related to
And the method that edge strip repairs cutting positioning on the big wing back rest of 737CL type aircrafts is carried out using the instrument.
Background technology
Boeing-737 CL types aircraft has run for many years as main force's type of aviation transport, and Aging Problem day is increasingly
Play, the increasing type after about 30000 pilot time of flying, the spy of big wing back rest main force support structure (edge strip on the back rest)
Determine fastener hole locations, penetrating crack generally occurs, have a strong impact on aircraft safety.
4.3 meters of edge strip total length on the big wing back rest, is L-type configuration, and spanwise extends, and upper flange side is embedded in big wing fuel tank
Inside, is connected with covering on the big wing, and lower flange edge lap is connected on the outside of fuel tank with fuel tank internal web.Fuel tank internal is assembled
Regional structure is complicated, narrow space.Performed on the big wing back rest in the repairing of edge strip according to Boeing Structure Repair Manual, cutting is changed
The upper edge strip for crackle occur is the key link repaired.Existing cutting method is directly aboard to upper edge strip RSS285
Position carries out line cutting, and then the repairing section bar again to upper edge strip carries out line cutting, stays enough enough surpluses, repeatedly upper to fly
Machine positioning repaiies file, to match the upper edge strip otch on aircraft.The method technique of this cutting is cumbersome, and new and old upper edge strip can be caused to cut
Mouth is inconsistent, and the precision of cutting is low, and risk is big, easily scraps edge strip and repairs section bar.
The content of the invention
First technical problem to be solved by this invention, is just to provide edge strip on a kind of big wing back rest of 737CL types aircraft
Repair position cutting tool.
Second technical problem to be solved by this invention, be just to provide a kind of carry out 737CL types and flies using above-mentioned instrument
The method that edge strip repairs positional dissection on the big wing back rest of machine.
Using tool and method of the invention, the cutting action of edge strip on the big wing back rest of 737CL type aircrafts can be simplified, subtracted
The limitation of few construction environment, it is ensured that edge strip line of cut repairs the consistent of section steel cutting line, greatly drop with edge strip on the big wing on the big wing
Low cutting replaces with the risk of edge strip, improves operating efficiency.
Above-mentioned first technical problem is solved, the technical solution adopted in the present invention is as follows：

The fastener hole of overlapping regions side is repaired corresponding to edge strip on the big wing back rest；
Upper flange pad 3 each one in pad 2 and lower flange, two pads it is unilateral on the hole that is provided with correspond respectively to restore
Hole in the upper and lower flange plate face of angle-piece, corresponding abutting end edge is provided with chamfering, and side corresponds to repairs the upper and lower of line of cut
Part；
One profile template 4, appearance profile is corresponding with the hole opened in plate face to pull down edge strip lower flange profile on the back rest scrapped
And hole, the butted line profile for being shaped as repairing line of cut of correspondence side；
One rectangular connecting sheets 6, are provided with hole thereon, corresponding to by profile template 4 and positioning the spliced connection of angle-piece 5
Hole；
Alignment pin and connector are some.
Described each component materials are aluminum alloy materials.
Described repairing line of cut is：The outer end protrusion of upper flange, the middle protrusion of lower flange.
Above-mentioned second technical problem is solved, the technical solution adopted in the present invention is as follows：
A kind of method that edge strip repairs cutting positioning on big wing back rest of 737CL types aircraft, its feature is comprised the following steps：
S1：Positioning angle-piece is overlapped on the outside of edge strip cutting zone on the big wing back rest, by upper and lower flange gasket correspondence
Be overlapped on inside edge strip, along positioning angle-piece, the line of cut profile upper edge strip of cutting of pad after being fixed with alignment pin；
S2:Positioning angle-piece is removed, positioning angle-piece and the profile on the basis of the fastener locations for restoring angle-piece
Template, then with connection sheet stationary positioned angle-piece and profile template；
S3:Positioning angle-piece and profile template sub-assembly are overlapped on into upper edge strip to repair on section bar, by repairing under section bar
The appearance profile dowelling assembly of flange, gets out fastener hole and (positions angle-style in the repairing section bar part for needing cutting to scrap
Fastener hole on part)；
S4:External form template and connection sheet are split out, stationary positioned angle-piece and upper and lower flange pad on section bar is repaired are cut
Cut to repair file and be made the big wing back rest and repair upper edge strip.
Compared with prior art, the invention has the advantages that：
One, realizes the repairing of offing normal of edge strip cutting on the big wing back rest, has effectively evaded the big wing fuel tank complexity position of aircraft
Limitation；
Two, simplify cutting and repair operation, it is to avoid the otch surplus that edge strip on the amendment back rest repairs section bar is repeated several times, carries
Operating efficiency high；
The three, intact line of cut positioning by edge strip on the big wing back rest has been copied on new repairing section bar, makes making
The big wing back rest repairs upper edge strip and is docked with edge strip otch on the big wing back rest on aircraft more identical, reduces repairing risk.
