Aerofoils and vertical Tails horizontal measurement and point print system and method

Abstract

The invention discloses a system and a method for dotting level survey dots of wings and a vertical tail of an airplane. The system adopts an industrial robot to operate a jumper bar dotting device with damping function driven by an air cylinder and dot level survey dots of the wings, and the wings are fixed on a wing posture adjusting and finish machining platform by a posture adjusting three-dimensional positioner, a flexible fixture and a clamping device. The dotting is as follows: firstly, a world coordinate system is constructed by a laser tracker to obtain space coordinates of position, posture and level survey spots of the robot; secondly, a moving path of the robot is planned so that the dotting device is controlled to reach the target position; thirdly, the dotting device is subjected to alignment through the laser tracker; and finally, the dotting motions are carried out by controlling a solenoid valve. While dot punching, blue annular marks are printed at the positions of the survey dots by a coloring head under the action of a spring. The system and the method improve the working efficiency through using the industrial robot, and the operation task has relative flexibility; and the industrial robot has higher repeat precision to ensure the precision of dotting.

Description

technical field [0001] The invention relates to a manufacturing system and method for aircraft wings and vertical tail level measurement points. Background technique [0002] In the finishing stage of aircraft wings and vertical tails, it is necessary to make horizontal measurement points on them, so as to check and evaluate the horizontal posture after the final assembly of the aircraft. In the current manufacturing process, the aircraft wings and vertical tail are first placed horizontally, and workers manually operate a series of spring indenters installed below the measurement points to strike the horizontal measurement points on the skin. Due to the large number of measurement points, each measurement point needs an inker, and the layout design of an inker can only solve the measurement point marking of one type of aircraft wing and vertical tail, which lacks flexibility. In addition, the inker takes up more work space and is inconvenient to operate and maintain. [0...

Problems solved by technology

Due to the large number of measurement points, each measurement point requires an inker, and the layout design of an inker can only solve the measurement points of one type of aircraft wing and vertical tail, which lacks flexibility.

In addition, the inker takes up a lot of work space and is inconvenient to operate and maintain
