Abstract
The invention discloses a tool for bonding a metal edge protector to composite blades. A front baffle is fixed to the front end of a bottom plate and a rear baffle is fixed to the rear portion of the bottom plate. One end, away from a propeller shaft, of an upper cover plate is supported on the side wall of the front baffle and the other end of the upper cover plate is supported on the side wall of the rear baffle. Two or more lower supporting blocks are fixedly arranged between the front baffle and the rear baffle. A containing groove matched with a corresponding position of one end, with no metal edge protector, of each blade is formed in each lower supporting block. Screw rods are fixed to the two ends of each lower supporting block. A rubber protection mat is fixed to the bottom face of each containing groove. Lug plates protrude from the positions, corresponding to the lower supporting blocks, of the upper cover plate. Holes are formed in the positions, corresponding to the screw rods, of the lug plates. The screw rods are placed in the holes and are pressed and fixed through locking nuts. A rubber mat is fixed to the inner wall of the upper cover plate and a heating component is wrapped by the rubber mat. By means of the tool, the metal edge protector is bonded to the composite blades. The bonding effect is good and no void points exist. The heat transfer effect is good and energy is saved. Besides, blade damage is avoided.
Description
Technical field
The present invention relates to a kind of instrument be glued to by metal hemming edge on composite material blade.
Background technique
In recent years, along with the development composite material of aeronautical technology is with its high specific strength, specific stiffness and good fatigue resistance and corrosion resistance obtain aboard to be applied widely, adopts the helicopter of composite material blade to be also widely used.Because composite material blade blade tip has very high linear velocity, very large by foreign object impact power, so blade tip part often needs bonded metal bound edge to strengthen the impact resistance of blade, the existing instrument be bonded in by metal hemming edge on blade is metal hemming edge die.The metal hemming edge and blade that scribble glue are placed in metal hemming edge die and carry out rigid pressurized, the position that existing metal hemming edge die contacts with metal hemming edge is metal, adopt very stiff and demanding crimping, like this because metal hemming edge die and metal hemming edge are all irregularly shaped, the position be easy to because error causes can not contact or contact unreal, causes crimping not in place, metal hemming edge and blade bonding unreal, there is imaginary point, easily come off, affect usability and the life-span of blade.Also have heating equipment to be enclosed in the outside of metal hemming edge die, by metal heat transfer to metal hemming edge, its heat-transfer effect is poor, and a part of heat of peripheral heating equipment falls apart in air, waste heat energy.
Summary of the invention
Object of the present invention solves the above-mentioned problems in the prior art exactly, and provide a kind of instrument be glued to by metal hemming edge on composite material blade, adopt this instrument to be glued on composite material blade by metal hemming edge, its adhesive effect is good, does not have imaginary point; Its heat-transfer effect is good, saves energy; And can not damaged blade.
For achieving the above object, technical solution of the present invention is: a kind of instrument be glued to by metal hemming edge on composite material blade, it comprise base plate, front screen, backboard, more than two pieces lower support block, oar axle dunnage, the upper cover plate, rubber pad, rubber protection pad, the heating module be wrapped in rubber pad that match with metal hemming edge inner wall shape, crimp screw rod and nut; Front screen is fixed on the front end of base plate, and upper cover plate is supported on its sidewall away from one end of oar axle; Backboard is fixed on the rear portion of base plate, and the upper cover plate the other end is supported on its sidewall; The rear end of base plate is fixed with oar axle dunnage; Between front screen and backboard, be fixed with the lower support block of more than two pieces, lower support block has the receiving groove not having one end opposite position of metal hemming edge to match with blade, two ends are fixed with screw rod respectively; Bottom surface is fixed with rubber protection pad to receiving groove; Upper cover plate leans out otic placode in the position corresponding with each lower support block, and otic placode has hole in the position corresponding with screw rod, and screw rod is placed in hole, is fixed by locking nut; Upper cover plate inwall is fixed with the rubber pad being enclosed with heating module.
Heating module described above is heating pipe or heating wire.
Below base plate described above, road wheel is installed.
During use, be placed in the receiving groove of lower support block by bonding blade, front end and back support are on front screen and backboard sidewall, and oar axle is supported in oar axle dunnage, metal hemming edge is placed in the upper end of blade, and upper cover plate is crimped on metal hemming edge by locking nut and screw rod.The present invention has installed rubber pad additional at the contact position of upper cover plate and metal hemming edge, and like this, upper cover plate and metal hemming edge are by rubber pad soft contact, it compensate for due to very stiff and demanding between metal and gap that is that cause, do not have gap after its crimping, its adhesive effect is good, does not have imaginary point; Heating module of the present invention is positioned at rubber sheet gasket, and it is directly metal hemming edge heating, and without the need to transmitting, directly, heat transfer effect is good, and it is positioned at upper cover plate in heating, and directly outside not exposed, its outside heat-transfer effect is poor, saves energy.Rubber pad and rubber protection pad protect blade impaired in the process of crimping.In a word, adopt the present invention to be glued on composite material blade by metal hemming edge, its adhesive effect is good, does not have imaginary point; Its heat-transfer effect is good, saves energy; And can not damaged blade.
