Airplane component attitude adjusting and butting system based on four numeric control positioners, attitude adjusting platform and mobile bracket and corresponding method

Abstract

The invention discloses an airplane component attitude adjusting and butting system based on four numeric control positioners, attitude adjusting platform and mobile bracket and a corresponding method. The system comprises a mobile bracket, an attitude adjusting platform, numeric control positioners, a numeric control positioner group guide rail, an upper computer, a ball hinge connection mechanism and a laser tracker. The attitude adjusting and butting method includes the following steps: 1) the mobile bracket is fixed onto the attitude adjusting platform and is supported by the numeric control positioner; 2) fuselage is arranged in place; 3) a site assembly coordinate system and a local coordinate system solidified on the fuselage are established; 4) the current attitude of fuselage A is measured and calculated; 5) motion path of the numeric control positioner is planned; 6) the attitude of the fuselage A is adjusted; 7) coordinates of a butt hole are measured and target attitude offuselage B is calculated; 8) the current attitude of fuselage B is calculated; 9) the attitude of the fuselage B is adjusted; 10) fuselage is butted; 11) the system is reset; 12) the mobile bracket is removed. The invention has the advantages that digitalized attitude adjusting and butting of airplane components are realized and adaptability is strong.

Description

technical field [0001] The invention relates to an aircraft component attitude adjustment and docking system and method based on four numerically controlled locators, attitude adjustment docking and moving brackets. Background technique [0002] In aircraft manufacturing, to complete the final assembly of the aircraft, the pose adjustment of the fuselage section must be realized first, and then the docking work can be carried out. The fuselage section is a special operation object, which has the characteristics of large volume and high quality. At the same time, it requires high accuracy in attitude adjustment and positioning, and the stress and deformation of the fuselage section should be small after assembly. At present, my country's aircraft attitude adjustment and docking system with independent intellectual property rights has just entered the application stage. Most of the popular assembly systems based on robot technology in the market are suitable for production lin...
