Problems solved by technology

That is, the entire manufacturing process of the flat tail from forming to complete assembly requires the cooperation of multiple tooling, and each tooling is relatively independent, resulting in high cost, and separate molding and separate assembly of the left and right parts of the flat tail can easily make the left and right parts of the flat tail consistent. Poor, not conducive to ensuring the consistency of the horizontal tail installation angle and dihedral angle, etc.

Embodiment 1

[0044] see Figure 1-Figure 5 As shown, the forming and assembling tool for the horizontal tail of the composite drone provided by the embodiment of the present invention includes a first side forming and assembling part 1 , a second side forming and assembling part 3 , a positioning shaft 4 , and a plurality of pressurized positioning parts 2 .

[0045] see figure 1 with figure 2 As shown, the first side molding assembly part 1 includes a first support frame 11 and a first side skin molding part 12, first positioning installation parts 111 are provided on both sides of the first support frame 11, and the first side skin molding part 12 is installed on the first support frame 11 and is located between the first positioning installation parts 111 on both sides. The upper side of the first side skin molding part 12 is provided with a first side left skin molding cavity and a first side right Skin molding cavity. That is, the first side skin forming part 12 can mold the first...

Embodiment 2

[0063] The second embodiment is a method for manufacturing the flat tail of a composite unmanned aerial vehicle, which can be manufactured using any one of the molding and assembly tooling in the first embodiment, including the following steps:

[0064] S1. Prepare the first left skin, the first right skin, the second left skin and the second right skin:

[0065] Lay prepreg in the first side left skin molding cavity, the first side right skin molding cavity, the second side left skin molding cavity and the second side right skin molding cavity, and perform sealing treatment after the laying is completed Put the first side molding assembly part and the second side molding assembly part into the oven as a whole, vacuumize and heat up to obtain the cured first side left skin, first side right skin, second side left skin and second side skin side right skin;

[0066] S2. Prepare the left skeleton and the right skeleton:

[0067] Lay a single-sided adhesive release cloth on the ...

Abstract

The invention relates to the technical field of unmanned aerial vehicles, in particular to a forming and assembling tool and a manufacturing method for composite unmanned aerial vehicle horizontal tails. The forming and assembling tool comprises a first side forming and assembling part, a second side forming and assembling part, a positioning shaft and a plurality of pressurizing and positioning parts. Through mutual cooperation of the first side forming and assembling part, the second side forming and assembling part, the positioning shaft and the pressurizing and positioning parts, skins ofhorizontal tails on the left side and the right side can be formed and assembled at the same time, The number of used tools is small, operation is easy, the consistency of the horizontal tails on theleft side and the right side is good due to simultaneous forming and assembling, the consistency of parameters such as the airfoil profile, the sweepback angle, the installation angle and the dihedralangle of the horizontal tails can be well guaranteed, and the consistency of the quality of the left and right horizontal tails is guaranteed.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a molding and assembly tooling and a manufacturing method of a flat tail of a composite unmanned aerial vehicle. Background technique [0002] In order to reduce the structural weight of the UAV and improve the flight range, some UAV horizontal tails are all-composite material structures, generally composed of upper and lower skins and criss-cross beam ribs between the upper and lower skins, and the joint angles are made by wet paste by hand. Sheets connect the ribs and the ribs to the skin. [0003] The forming and assembly tooling of the traditional flat tail is independently designed and manufactured. The forming tooling is only used for the forming of a single skin and other parts, and the left and right parts of the flat tail are assembled separately. That is, the entire manufacturing process of the flat tail from forming to complete assembly requires the c...
