[0002] The control surface refers to the aerodynamic wing surface that uses deflection in the airflow to generate missile balance and control force to control the flight of the missile. It is also called the control surface. The control surface is the control surface of the aircraft, which is generally in three directions. The horizontal direction is called the elevator, which is the horizontal tail, responsible for controlling the rise and fall of the aircraft.

When the molds are closed, the rudder surface skin upper mold 10 and the rudder surface skin lower mold 20 jointly surround and form an assembly cavity 40, and at least two sides of the assembly cavity 40 are formed with avoidance observation ports 41; the positioning mechanism 30 is installed on the rudder surface skin upper mold 10 and / or the rudder surface skin lower mold 20, and is used to position and match with the rudder surface skeleton of the unmanned aerial vehicle rudder surface.

After the assembly of the rudder skeleton is completed, the rudder skin upper mold 10 and the rudder skin lower mold 20 are molded together, so that the rudder surface upper skin, the rudder surface lower skin and the rudder skeleton are assembled. Since the visualization device for the matching mold of the unmanned aerial vehicle rudder assembly can complete the assembly of the rudder skeleton and the molding of the rudder skeleton and the rudder skin, the process flow is simplified and the production efficiency is improved.

[0032] In addition, during the mold closing process, the avoidance observation port 41 allows the user to observe the upper skin of the rudder surface, the lower skin of the rudder surface, the rudder surface frame and the rudder surface, thereby realizing visualization of the mold closing, facilitating the discovery of rudder surface deformation problems during the mold closing process, and facilitating the discovery and removal of excess debris, thereby effectively improving the assembly quality of the rudder surface. After the mold closing is completed, the edge of the rudder surface can also be observed through the avoidance observation port 41 to confirm the mold closing quality.

[0033] In some optional embodiments, avoidance observation ports 41 are provided on the front, left and right sides of the assembly cavity 40. Based on the shape of the rudder surface, the upper skin of the rudder surface and the lower skin of the rudder surface are spaced apart from each other at a large distance on the front, left and right sides of the assembly cavity 40, thereby facilitating the arrangement of the avoidance observation ports 41. Since the interior of the assembly cavity 40 can be observed from multiple sides, the mold quality can be observed conveniently.

[0034] See also Figure 3 and Figure 4 In some optional embodiments, the rudder surface skin upper mold 10 includes an upper mold bracket 11 and an upper module 12 arranged at the bottom of the upper mold bracket 11; the rudder surface skin lower mold 20 includes a lower mold bracket 21 and a lower module 22 arranged at the top of the lower mold bracket 21.

[0039] See also Figure 4 In some optional embodiments, a plurality of positioning supports 23 are provided on the lower mold 20 of the rudder skin, the positioning supports 23 are located at the side of the assembly cavity 40, and the positioning mechanism 30 is provided on the positioning supports 23. In this embodiment, positioning supports 23 are provided on the front side, left side and right side of the lower mold support 21, and a plurality of positioning supports 23 are arranged on the front side of the lower mold support 21, the second mounting seat is correspondingly mounted on the positioning support 23 on the left side or right side of the lower mold support 21, and the third mounting seat and the fourth mounting seat are mounted on the positioning support 23 on the front side of the lower mold support 21.

[0041] In some optional embodiments, the rudder surface skin lower mold 20 and / or the rudder surface skin upper mold 10 are provided with rubber pads for contacting with the skin of the drone rudder surface, the rubber pads are located in the assembly cavity 40, and the rubber pads have a certain elasticity. The rubber pads of the rudder surface skin upper mold 10 can be used to protect the rudder surface skin and improve the appearance quality of the rudder surface skin after mold closing, and the rubber pads of the rudder surface skin lower mold 20 can be used to protect the rudder surface lower skin and improve the appearance quality of the rudder surface lower skin after mold closing. The thickness of the rubber pad can be controlled between 0.05mm-0.2mm, so that the thickness of the rubber pad should not be too thick, because the stress at different positions of the rudder surface is different. If the rubber pad is too thick, it will cause the rubber pad to be excessively deformed at the position where it is subjected to greater force, resulting in unevenness of the rubber pad, affecting the appearance quality of the skin after mold closing.
