Description
Technical field
[1] the present invention relates to a kind of clamping means and apparatus for fastening that is used to clamp the aircraft connecting elements.
Background technology
[2] in present commercial aircraft, the connection between aircraft fuselage and the aircraft wing must be in the extreme accurately with firm.In addition, be very important being connected at the interface wing being regulated very accurately of fuselage, because the length of wing, several millimeters closed tolerance can cause at place, wing end several centimetres high tolerance.For example, if the aligning between starboard wing and the fuselage is different with the aligning between port wing and the fuselage, then can cause adverse influence to the flight characteristics of aircraft.
[3] therefore, the connecting elements that wing is connected to aircraft must very accurately and exactly be made.Connecting elements can for example be the angle counterpart, and one face is connected to aircraft fuselage and another face is connected to aircraft wing.Because the size of aircraft wing is very big, the impossible accurate and single wing of manufacturing dimension, thus each wing has different tolerances.Must come these tolerances are regulated and compensated by connecting elements, obtain same aligning and adjusting, to guarantee best flight characteristics with the wing of guaranteeing aircraft.Therefore, connecting counterpart must be adaptive respectively with each wing by the milling joint face, so that the alignment error between the aircraft wing minimizes.
[4] each connection counterpart must be made individually to regulate wing with respect to fuselage.Therefore, the counterpart face that is connected with wing or fuselage in angle is by specification and the tolerance of milling (mill) to expectation.Normally, connecting elements is clamped on the apparatus for fastening like this, wherein, each face, is that each machined surface of connecting elements all mechanically is clamped on the seating surface of described apparatus for fastening.Therefore, each machined surface all must be clamped on the apparatus for fastening by for example several screw clamps, with clamping engagement part accurately and stably.
[5] by mechanically clamping all fixed component machined surfaces, clamping is an overdetermination.When the Milling Process face, for example temperature and other physical parameter have been changed, and make the material of fixed component expand.Because the formed overdetermination of mechanical grip has produced tension force---it causes injustice, the distortion in the machined surface and curls.This has caused for wing being connected to the flagrant tolerance of fuselage.Therefore, must carry out several milling steps to guarantee the expectation precision and the closed tolerance of machined surface.
Summary of the invention
[6] an object of the present invention is to provide a kind of clamping means that alleviate stress for the angle counterpart.
[7] this can realize by a kind of clamping means and apparatus for fastening that is used to clamp the aircraft connecting elements.
