Description
Technical field
The present invention relates to a kind of instrument being glued to metal hemming edge on composite material blade.
Background technology
In recent years, composite material is continued to develop with its high specific strength with aeronautical technology, specific stiffness and good anti-
Fatigability and corrosion resistance are widely applied aboard, are also made extensively using the helicopter of composite material blade
With.It is very big by foreign object impact power because composite material blade blade tip has very high linear velocity, so blade tip part generally requires to glue
The impact resistance of metal hemming edge enhancing blade is connect, and existing instrument metal hemming edge being bonded on blade is that metal hemming edge is recessed
Mould.The metal hemming edge for scribbling glue and blade are placed in metal hemming edge cavity plate and carry out rigid pressurized, existing metal hemming edge cavity plate with
The position of metal hemming edge contact is metal, using very stiff and demanding crimping, so since metal hemming edge cavity plate and metal hemming edge be not all for
Regular shape, it is easy to since the position that error causes to have cannot contact or contact unreal, cause to crimp not in place, metal hemming edge
It is unreal with blade bonding, there is imaginary point, easily come off, influence performance and the service life of blade.Also heating unit is enclosed in gold
Belong to the outside of bound edge cavity plate, by metal heat transfer to metal hemming edge, its heat-transfer effect is poor, and a part of heat of peripheral heating unit
It is scattered in air, wastes thermal energy.
The content of the invention
The purpose of the present invention is exactly to solve the above-mentioned problems in the prior art, there is provided metal hemming edge is glued to by one kind
Metal hemming edge, is glued on composite material blade, its adhesive effect is good, does not have by the instrument on composite material blade using the instrument
There is imaginary point；Its heat-transfer effect is good, saves energy；And will not damaged blade.
To achieve the above object, technical solution of the invention is：Metal hemming edge is glued to composite material paddle by one kind
Instrument on leaf, it includes bottom plate, front apron, rear baffle, more than two pieces of lower supporting block, paddle shaft support plate and metal hemming edge
Upper cover plate that inner wall shape matches, rubber pad, rubber protection pad, the heating component being wrapped in rubber pad, crimping screw rod and
Nut；Front apron is fixed on the front end of bottom plate, and the one end of upper cover plate away from paddle shaft is supported on its side wall；Rear baffle is fixed on bottom
The rear portion of plate, the upper cover plate other end are supported on its side wall；The rear end of bottom plate is fixed with paddle shaft support plate；In front apron and rear gear
More than two pieces of lower supporting block is fixed between plate, is had in lower supporting block opposite with one end that blade does not have metal hemming edge
The holding tank that position matches is answered, both ends are respectively fixed with screw rod；Accommodate and be fixed with rubber protection pad in groove bottom；Upper cover plate exists
Otic placode is leant out with each lower corresponding position of supporting block, otic placode is being provided with hole with the corresponding position of screw rod, and screw rod is placed in hole,
It is fixed by locking nut；The rubber pad for being enclosed with heating component is fixed with upper cover plate inner wall.
Heating component described above is heating tube or heater strip.
Bottom plate described above is mounted below traveling wheel.
In use, glued blade is placed in the holding tank of lower supporting block, front end and back support front apron and after
In baffle sidewall, paddle shaft is supported in paddle shaft support plate, and metal hemming edge is placed in the upper end of blade, and upper cover plate is by locking nut and spiral shell
Bar is crimped on metal hemming edge.The present invention has installed rubber pad additional in the contact position of upper cover plate and metal hemming edge, in this way, upper cover plate
With metal hemming edge by rubber pad soft contact, it compensate for the gap caused by very stiff and demanding between metal, after it is crimped
There is no gap, its adhesive effect is good, without imaginary point；The heating component of the present invention is located in rubber sheet gasket, it is directly metal bag
Side is heated, and without transmission, heating is direct, and heat transfer effect is good, it be located in upper cover plate, without it is direct it is exposed outside, its to
Outer heat-transfer effect is poor, saves energy.Rubber pad and rubber protection pad protect blade to be damaged during crimping.In short, using
Metal hemming edge is glued on composite material blade by the present invention, its adhesive effect is good, without imaginary point；Its heat-transfer effect is good, saves
Energy；And will not damaged blade.
