Abstract

The invention relates to an angle adjusting mechanism for a wing outer end feeler lever. The angle adjusting mechanism is composed of a feeler lever joint (1), a knuckle bearing (2), a bearing support (3), a nut (4), a feeler lever end (5), tile covers (6), bolts I (7), bolts II (8), brackets (9), a feeler lever middle portion (10), toothed pads (11) and toothed boards (12). When the feeler lever middle portion (10) is adjusted to the proper position, the bolts II (8) are locked, sawteeth of the toothed pads (11) and sawteeth of the toothed boards (12) are engaged, the feeler lever middle portion (10) is limited, and the feeler lever is fixed after the angle of the feeler lever is adjusted. By the adoption of the angle adjusting mechanism, the requirement for adjusting the angle of the feeler lever can be met, and the feeler lever can also be completely fixed when the adjusted position is proper.

Description

A kind of angle adjusting mechanism of wing outer end feeler lever

Technical field

The present invention relates to a kind of fixed wing airplane structural design, be particularly well-suited to the design of wing outer end feeler lever.

Background technology

At present on fixed wing airplane wing, increase equipment carries out reequiping varied, technology relative maturity, installing overhanging feeler lever additional in wing outer end is also one of common approach in repacking, general version is to connect hold-down support on suitable two ribs of wing outer end span, coordinate the fixing feeler lever of the FE Tiler being spirally connected, use bolt to be completely fixed. This kind of version Stability Analysis of Structures, it is easy to implement, easy to assembly, but equipment can not do the adjustment of any angle. When feeler lever is installed the precision equipments such as some exploration, tests, require over the error changing feeler lever angle to compensate fit on accumulation, or when needing to regulate the relative position of detecting devices and change test data, the hold-down support version of prior art cannot meet instructions for use, it is necessary to formulates a set of new scheme.

Summary of the invention

$\mathrm{\α}=2\×\arcsin \frac{L}{2R}$

�� degree of regulation unit is degree

L dentiform gasket and tooth plate tooth pitch unit are millimeter

R center of rotation is millimeter to stay bolt axial line distance unit

When in the middle part of feeler lever, 10 adjustment are to correct position, clamping screw II 8, the sawtooth of dentiform gasket 11 and tooth plate 12 is meshed, and carries out spacing in the middle part of feeler lever 10, completes fixing after feeler lever angular adjustment.

Beneficial effects of the present invention:

It is stable that this invention has overall structure, structure takes up room little, it is to avoid the advantage such as complex parts and closed assembly appearance, has effectively used the engaging structure of sawtooth, has had feature easy to adjust, accurate positioning. Function aspects can make feeler lever in place on be completely fixed, as required the angle of feeler lever can be carried out again quick and easy convenient adjustment, the effective position changing equipment, compensate the error of accumulation in each link, and degree of regulation can be provided by simple calculating, offer help for structural design from now on, provide strong technical support and help for the monitoring of later aeronautical meteorology, geological prospecting or other precision measurements etc.
