Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, one end of the heating wire to be laid is pre-positioned on the laid composite material, and the wire laying head is fixed on the mechanical arm through the flange 1 . The mechanical arm drives the wire laying head to lay the wire according to the predetermined wire laying track. The heating wire is wound on the wire roller 19, and the wire feeding direction is changed through the No. 1 guide roller 4 and the No. 2 guide roller 6, and enters the glue pool through the No. 3 guide roller 7 14. Under the auxiliary transmission of No. 4 guide roller 2 and No. 5 guide roller 13, the heating wire is pre-impregnated with glue through the glue pool 14, and finally adjusts the position through the guide wire ball 16 fixed on the ball bracket 15 to lay the wire.

[0026] Such as figure 2 As shown, the wire roller 19 is assembled with the elec...

Abstract

A fiber placement head used for helicopter rotor wing anti-icing / de-icing component heating wire fiber placement positioning belongs to the composite material molding technology field. The fiber placement head is installed on a mechanical arm through a flange plate. The fiber placement head comprises a silk roller, a guide roller, an electromagnetic device, a conductive slip ring, a fan and an electric heating coil used for heating a presoak filament so as to accelerate solidification. The electromagnetic device is formed through connecting a stator magnet and a rotor coil to fan blades. In the invention, the mechanical arm is used to drive the electromagnetic device to rotate and then electric energy is generated so as to provide power for the fan and the electric heating coil so that the presoak filament can be rapidly solidified under effects of hot air and a heating coil and laying and positioning are accurate. The fiber placement head possesses characteristics that energy consumption is low; the device is simple and flexible; and an application field is wide and so on. Requirements of heating wire distance changing in a helicopter rotor wing anti-icing / de-icing component and complex structure laying can be satisfied.

Description

technical field [0001] The invention relates to a wire laying head for positioning electric heating wires of a helicopter rotor anti-icing / deicing component, and belongs to the technical field of rotor anti-icing and deicing. Background technique [0002] Helicopter rotor anti-icing / de-icing components are composed of iron-coated surface, insulating heat transfer layer, heating wire and insulating heat insulating layer, which is a kind of composite material. Among them, the heating wire in the anti-icing / de-icing component mostly adopts nickel-chromium alloy thin wire, the diameter is about 0.2 mm, and the elastic strength is high and it is difficult to form. The heating wire is easily deformed and dislocated during the wire laying process, and it is difficult to accurately locate the shape of the wire laying. [0003] The laying head is the most critical functional part of the related laying machine. A typical machine tool laying head is generally composed of a guide whee...
