Description
Technical field
The invention belongs to blade deflection metrology technologies, are related to a kind of measurement method of composite material blade amount of deflection.
Background technology
After the completion of helicopter blade assembles, before delivering installation, the amount of deflection for detecting every blade is needed (to use under normal circumstances
In the rigidity and flexibility of verification blade).Currently, the model of helicopter is on the increase, and since helicopter tonnage is of different sizes, paddle
The length of leaf is significantly different, therefore the deflection metrology tooling needed is increased significantly also with increasing for model, and such case causes
The increase of aircraft manufacturing cost and the period for newly grinding type are elongated, while the usable floor area for also resulting in factory is increasingly tight
.
Invention content
The purpose of the present invention is：The object of the present invention is to provide a kind of simple and practical composite material blade amounts of deflection
Measurement method and a kind of general deflection metrology tooling reduce the difficulty that composite material blade measures, and improve composite material blade and scratch
The accuracy measured is spent, the versatility of composite material blade deflection metrology method is improved, reduction increases new because newly grinding model
Tooling reduces production cost, shortens development and production cycle, saves the usable floor area of workshop, realizes energy-saving.
The technical scheme is that：
True amount of deflection of this measurement method analog composite material blade under installation state, passes through a kind of general composite wood
Expect that blade deflection metrology tooling realizes the purpose measured.
Composite material blade deflection measuring apparatus：Including base unit, quick-replaceable clamping unit, combined track unit with
And measuring unit；Base unit is the cuboid type frame structure being welded to form by rectangular steel pipe, upper surface have installation positioning jack,
Base unit is installed on facility floor by three coordinate settings (ensureing levelness), and the base unit is for installing quick-replaceable folder
Hold unit；Quick-replaceable clamping unit includes U-shaped clamping head and positioning pin, for blade ontology to be clamped；Combined track unit packet
Include two square steel parallel orbits and multiple fixing screws；Measuring unit is made of a long graduated scale and a sliding bottom；
Sliding bottom includes holding screw, bearing, oilless bearing, nut, locating rod and cuboid framework, the bottom peace of measuring unit
The pulley of dress and combined track unit matching.
Composite material blade deflection metrology step：
One, the quick-replaceable clamping unit of corresponding model is installed on base unit.
Two, composite material blade is mounted in quick-replaceable clamping unit.Passed through using two sets of screws and nut compound
The root of composite material blade is horizontally fixed in quick-replaceable clamping unit by the bush hole of material blade.
Three, so that composite material blade naturally droops and reaches stable, measuring unit is moved by combined track unit
Close to the tip of composite material blade.
Four, long graduated scale is finely tuned, makes long graduated scale and composite material blade tip close to and gentle touchdown.
Five, reading L of the reading blade tip in long graduated scale.
It is an advantage of the invention that：The present invention is versatile, can only be needed more according to the needs of different model helicopter blade
It changes ' fast changeable clamping unit ' and traverse measurement unit can be achieved with Multiple Type blade (including different length) amount of deflection
It measures.So that when helicopter newly grinds model without remanufacturing new tooling, only needing special one, ' Ke Kuaisugenghuan clamping is single
Member ', be on the increase to solve the deflection metrology tooling quantity in helicopter development process, develops manufacture experimently the production cycle it is long,
The problem of manufacturing cost height, workshop usable floor area growing tension.
