Technical Field

The invention relates to the technical field of airplane structural member positioning, in particular to a symmetrical positioning tool and a symmetrical positioning method for an airplane composite material structural member.

Background

The C919 large-scale passenger plane vertical tail wing box section force bearing front and rear beams are integrally formed by adopting a composite material, the section is I-shaped, the outer edge strips on two sides are designed with an opening angle and a closing angle, the size is as long as 7 meters, the composite material is easy to deform after part characteristics are cured, particularly the outer edge strips have an irregular angle springback phenomenon after part forming, the positioning is inaccurate, so that after assembly, the wall plates cannot be perfectly attached, errors are accumulated to the appearance, the overall aerodynamic appearance is ultra-poor, wing surface type parts are used as an airplane control surface structure, the requirement on the symmetry of the appearance is stricter than that of a plane body and the like, in order to enable high-quality products to be assembled, the selection of a positioning method is particularly important, the influence caused by deformation is difficult to compensate for some traditional positioning modes, and therefore, a new positioning tool and a method are required to control the beam positioning accuracy.

Disclosure of Invention

In order to solve the above problems, in order to achieve the above object, the patent adopts the following technical solutions: the utility model provides a be used for aircraft combined material structure symmetric location frock, the jackscrew dog passes through the supporting shoe to be connected with the inside upper end in frock frame left side, and the inside lower extreme symmetry in frock frame left side is equipped with the jackscrew dog, and frock frame left side, right side respectively are equipped with mated movable guide, and movable guide's slip direction is the horizontal slip, and the inside upper right side of frock frame and right downside are equipped with digital display symmetry indicator respectively, digital display symmetry indicator is fixed with the frock frame through a plurality of location auricles.

The symmetrical positioning tool for the composite material structural part of the airplane is characterized in that at least two pairs of adjustable moving guide rails are arranged.

The symmetrical positioning tool for the composite material structural part of the airplane is characterized in that the adjustable movable guide rail is provided with a clamping device.

The symmetrical positioning tool for the composite material structural part of the airplane is characterized in that universal wheels are arranged between the clamping device and the adjustable moving guide rail.

The symmetrical location frock that is used for aircraft combined material structure spare of foretell, the model of digital display symmetry indicator be: 543 and 782B.

A symmetrical positioning method for an airplane composite structural member is characterized in that a clamping device and a jackscrew stop block on a movable guide rail are adjusted according to the size and the position of a workpiece, the workpiece is clamped by the clamping device and the jackscrew stop block, a digital display symmetrical indicator is started, a telescopic probe on the digital display symmetrical indicator is contacted with the surface of the workpiece, and when the jackscrew stop block and the movable guide rail are finely adjusted to enable absolute values of degrees on the digital display symmetrical indicator to be close to or consistent with each other, positioning is completed.

The invention has the beneficial effects that: the scheme is applied to the vertical tails 10001, 10101 and 10102, completely meets the requirements of engineering and customers, improves the satisfaction of companies in customer eyes, and finally delivers the products qualified for the customers. Meanwhile, the method has wide application range and can be suitable for similar structure cases.
