Abstract
The invention relates to a testing method of integral panel parts with double curvatures; the testing method comprises the following steps of: (1) drawing a plurality of parallel lines which are vertical to the axes of the panel parts according to the positions of main force bearing structures of the panel parts and formulating positions put forward by manufactures; (2) collecting a data set of curvatures of each parallel line; (3) manufacturing a group of testing clamping plates, wherein bottom surfaces of the testing clamping plates are on the same horizontal surface, the testing clamping plates are vertical to the horizontal surface, and a curved surface which is consistent with the curvature of the corresponding parallel line is arranged on the upper end surface of each testing clamping plate; (4) fixing the testing clamping plates on the horizontal surface, ensuring gaps to be consistent with the positions of the corresponding parallel lines; (5) placing the integral panel parts with the double curvatures on the group of testing clamping plates, wherein the parallel lines are coincided with the corresponding testing clamping plates; and carrying out the curvature measurement on the parts by using a plug gauge. The testing method is used for testing the double curvature appearance surface of the parts by adopting the testing clamping plates and has the advantages of not only reducing the time required for production, but also increasing the accuracy of testing, being convenient for testing and saving time and labor.
Description
Technical field
The present invention relates to a kind of method of inspection of hyperbolic degree integral wall plate parts, be used for check hyperbolic degree integral panel class part forming.
Background technology
Along with the present generation aircraft performance improves constantly, integral structure component has become the main load workpiece of extensive employing.Adopt one-piece construction can reduce part and number of connecting pieces, simplify rapport, reduce the assembly work amount, assembly deflections is little, reduces cost greatly.Wherein whole high rib hyperbolic degree wallboard class part has characteristics such as smooth surface, strength-weight ratio is high, impermeability is good with its structure and is widely used in fields such as Aeronautics and Astronautics, especially is applied to aircraft outer wing, central wing, vertical fin etc. and has in the vitals of aerodynamic configuration.At present, the process commonly used of this type of part is to adopt the part of the dull and stereotyped state of numerical control machining center milling earlier, utilizes technology such as press-bending, shot-peening to be shaped then.
But whether check hyperbolic degree part forming the qualified difficult point that becomes check; Conventional check system is to adopt the mould tire; The manufacturing data set that the mould tire is provided by loft model designer by the frock designer is designed the mould tire of the theoretical profile of part under the theory state; Give mould tire factory, the part forming workshop is given after producing the mould tire of wooden or steel by mould tire factory, and the checker is put into part on the mould tire and checks.Exist in this process the production cycle long, can't guarantee by node pay part, frock inaccurate coordination, factor such as location is inaccurate, data tracking is untimely, and the mould tire floor area of producing is big, clamping is difficult, is unfavorable for field test.
Summary of the invention
The technical matters that the present invention will solve provides a kind of method of inspection of hyperbolic degree integral wall plate parts; This method adopts the hyperbolic degree external surface of the formal testing part of check clamp, has not only reduced and has produced the needed time, and improved the accuracy of check; Check is convenient, and is time saving and energy saving.
For overcoming the above problems, concrete technical scheme of the present invention is following: a kind of method of inspection of hyperbolic degree integral wall plate parts is characterized in that may further comprise the steps:
1) presses the main load-carrying construction position of wall panel parts and the formulation position that factory proposes, require some the parallel lines of picture perpendicular to axis of workpiece;
2) the curvature data set of every parallel lines of collection;
3) make one group of bottom surface at same surface level, and perpendicular to the check clamp of surface level, each check clamp upper surface is provided with and the consistent curved surface of pairing parallel lines curvature;
4) will check clamp to be fixed on the surface level, and guarantee spacing and set and corresponding parallel lines position consistency;
5) hyperbolic degree integral wall plate parts is placed on this group check clamp, parallel lines overlap with pairing check clamp, and the curvature of using feeler gauge to carry out part is measured.
The method of inspection of this hyperbolic degree integral wall plate parts, as long as provide the data set of tangent plane, factory can make clamp, and then carries out the assembling of fixed position, has saved the production cycle greatly; And what clamp provided is the trend of part edge, theoretical margin, and main axial location and tangent plane make the line white silk become face; Integrade theory with practice; Judge more easily be shaped whether accurate, and the curved surface of clamp more near with the profile of theory state, make check more accurate; Between each check clamp distance is arranged all, the accuracy of feeler gauge check forming parts easy to use judges easily whether part forming is qualified, and check speed is fast, has improved the speed of check greatly.

Embodiment
A kind of method of inspection of hyperbolic degree integral wall plate parts is characterized in that may further comprise the steps:
1) as shown in Figure 1, press the main load-carrying construction position of wall panel parts and the formulation position that factory proposes, require some the parallel lines of picture perpendicular to axis of workpiece; The formulation position that described main load-carrying construction position and factory propose is generally main load-carrying construction position; Comprise wall, rib and long purlin axis etc., the rib heights of this position is exactly the thickness of wallboard usually, during moulding; As benchmark, carry out horizontal or vertical bent into shape with this position;
2) gather the curvature data set of every parallel lines, described data set comprises laterally, size longitudinally, with and curvature;
3) make one group of bottom surface at same surface level, and perpendicular to the check clamp of surface level, as shown in Figure 3, each check clamp upper surface is provided with and the consistent curved surface of the pairing parallel lines curvature of integral wall plate parts;
4) as shown in Figure 2, will check clamp to be fixed on the surface level, guarantee spacing and set and corresponding parallel lines position consistency;
5) hyperbolic degree integral wall plate parts is placed on this group check clamp; Parallel lines overlap with pairing check clamp; The curvature of using feeler gauge to carry out part is measured; When the slit that hyperbolic degree integral wall plate parts and a certain check clamp exist surpasses the size of feeler gauge, can judge that then the curvature of this hyperbolic degree integral wall plate parts is defective.
