Description
Technical field
The application is related to the oscillation time-effect method of airplane parts, particularly a kind of straightening method on carrier floor.
Background technology
In Aircraft Production particularly large aircraft production, often a value is then hundreds of up to ten million easily for large parts,
Value of the product is very big, so need especially to treasure, it is lower, it is necessary to as far as possible in the case where ensureing the basic premise of product quality and flight safety
Reduce the process loss of manufacturing process.Meanwhile aircraft manufacture course of products has to structural stress and structure physicochemical characteristics again
It is extremely important, it is necessary to the elimination inside parts stress and erection stress of maximum possible.
The floor of carrier just belongs to large parts, and its length is typically more than ten meters, and section general thickness is only
For 50mm or so, its section belongs to open-ended cavity structure, and section wall thickness is only 5-6mm, and its part pertains generally to thin-wall long and thin type,
Once deformation is difficult processing.According to the needs of aircraft development and later maintenance, it is necessary to be corrected shape to the floor of deformation, elasticity is allowed
The floor of small range deformation reaches assembling requirement.So used for carrier floor in manufacture early stage or later stage
Deformation in journey, which is made, reprocesses, it is necessary to develops a kind of straightening method.
The content of the invention
The purpose of the application is to provide a kind of carrier floor straightening method, and this method is with going for carrier
The correction of deformation of the plate during manufacture early stage or later stage use.
To achieve the above objectives, the application, which adopts the following technical scheme that, is achieved：
A kind of carrier floor straightening method, it is characterised in that including floor, fill-in pad, clamping plate, jacking block, switch block, limit
Position block, puller strap, are mainly comprised the following steps：
1st, floor total length sets gradually jacking block, switch block, limited block, jacking block and switch block, limited block point row floor the right and left,
Jacking block, switch block carry out holding out against setting according to physical location, and limited block is set and the equidistant gap of flooring product theoretical position, between equidistant
Gap value is beyond the 1/3 of deformation range；
2nd, floor middle opening cavity body structure punishment multistage (typically may be configured as 5 sections) is provided with the uniform thickness of required precision
Fill-in pad；
3rd, both sides set clamping plate, clamping plate inner side and floor topographies above and below floor, and splint position is according to fill-in pad position
Put segmentation arrangement；
4th, floor is fixed on middle clamping with upper and lower two clamping plates；
5th, held out against respectively along puller strap opposite direction among floor along puller strap positive direction, switch block in floor one end with jacking block
Floor both sides, limited block are arranged on the other end on floor along puller strap opposite direction and remained at a school or university after graduation as a faculty member in advance shape distance with floor edge；
6th, outwards floor is pulled at limited block always with puller strap, it is fixed；
7th, failure is stood, dither was carried out to floor deformation position top and bottom with dither instrument every 1 hour；
8th, failure 72 hours are stood, complete school shape.
The advantages of the application, which is make use of, is plastically deformed the principles such as spacing control and dither, realizes carrier
Flat, flat, long, cavity type parts are had and are generally applicable by the correction of deformation of the floor during manufacture early stage or later stage use
Property.
The application is described in further detail below in conjunction with drawings and Examples.

Embodiment
Referring to Fig. 1~Fig. 2, a kind of carrier floor straightening method, its structure is mainly by floor 1, fill-in pad 2, clamping plate
3rd, jacking block 4, switch block 5, limited block 6, puller strap 7 etc. form；
First, on floor 1, total length sets gradually jacking block 4, switch block 5, limited block 6, and jacking block 4 divides row with switch block 5, limited block 6
The right and left of floor 1, jacking block 4, switch block 5 carry out holding out against setting according to physical location, and limited block 6 sets theoretical with the product of floor 1
The equidistant gap 8 in position, equidistant gap width 8 are beyond the 1/3 of deformation range；
Secondly, on floor 1, middle opening cavity body structure punishment multistage (typically may be configured as 5 sections) is provided with required precision
Uniform thickness fill-in pad 2；
3rd, clamping plate 3, the inner side of clamping plate 3 and the topographies of floor 1 are set on both sides about 1 on floor, the position of clamping plate 3 according to
The location segment of fill-in pad 2 is arranged.
4th, floor 1 is fixed on middle clamping with upper and lower two clamping plates 3；
5th, with jacking block 4 the one end of floor 1 along the positive direction of puller strap 7, switch block 5 among floor 1 along the negative side of puller strap 7
To holding out against the both sides of floor 1 respectively, limited block 6 is arranged on the other end on floor 1 and pre- with the edge of floor 1 along the opposite direction of puller strap 7
Shape of remaining at a school or university after graduation as a faculty member distance；
6th, outwards floor 1 is pulled at limited block 6 always with puller strap 7, it is fixed；
7th, failure is stood, dither was carried out to the deformation position top and bottom of floor 1 with dither instrument every 1 hour；
Finally, failure 72 hours are stood, complete school shape.
