Abstract

The invention relates to an automatic wing-body docking hole-making system and a method, which belongs to the technical field of operating transport. The method comprises the following steps: mainly utilizing the principle of magnetic positioning to firstly determine the projection position of a blind hole on the outer surface of a wing body and make a mark point; secondly, determining the pose of the mark point in a coordinate system of a hole-making device by image processing technique; and finally, generating corresponding motion control instructions to control a hole making unit to complete the processing of the hole according to the pose of the mark point. The system mainly comprises a hole positioning unit (7000), the hole making unit (1000), a normal vector detection unit (2000), a normal vector pose-adjusting mechanism (3000), a movable vehicle body (4000) and a central control unit (5000). The method and the system can better solve the processing problem of wing-body docking connecting holes.

Description

technical field

[0001] The invention relates to an automatic hole-making system and method for wing-body docking, and belongs to the technical field of operation transportation. Background technique

[0002] Docking hole making is a key link in the assembly of wing and body. The efficiency of hole making directly restricts the aircraft assembly cycle, and the quality of hole making will also directly affect the fatigue resistance of the connected structural parts. Especially with the development of thin-walled, integrated and complex aerospace structural parts, the requirements for long life, high quality and high efficiency of the whole machine structure, and the large increase in the amount of difficult-to-machine materials such as composite materials and titanium alloys, Make assembly holes more demanding and more precise than before.

[0003] Due to the influence of factors such as difficult positioning and clamping of the processing parts, narrow working environment, a...
