Embodiment Construction

[0066] The present invention is given further description below:

[0067] (1) See figure 1As shown, the present invention is an aircraft component attitude adjustment assembly system based on a six-degree-of-freedom parallel mechanism, which includes: an aircraft component attitude adjustment mechanism and a laser tracking system. The positional relationship between them is that the latter is arranged around the former. Wherein the aircraft component attitude adjustment mechanism is composed of an aircraft component 1, four branch chains (PSS branch chain 1, PSS branch chain 2, PPRS branch chain 1, PPRS branch chain 2), and a static platform 24. The aircraft part 1 is connected with four branch chains through four spherical joints 2, 7, 12, 18, and the guide rails 6, 11 and the lower guide rails 17, 23 are fixed on the static platform 24. The laser tracking system consists of a laser tracker 26, a target mirror 25 and a laser reflective ball 27. The model of the laser tracke...

Abstract

The invention discloses an aircraft component attitude adjusting assembly system based on a parallel mechanism with six degrees of freedom, comprising an aircraft part attitude adjusting structure and a laser tracking system, wherein the position relationship therebetween is that the laser tracking system is arranged around the aircraft part attitude adjusting structure. The aircraft component attitude adjusting mechanism comprises an aircraft part the attitude of which to be adjusted, two PSS branch chains, two PRRS branch chains, a quiet platform for fixing the guide rails at the lowest ends of the four branch chains, the position relationship is as follows: two ends of the two PSS branch chains are connected with an aircraft part and a spherical hinge auxiliary sliding block through a spherical hinge, the guide rails are fixed on the quiet platform; one end of the two PRRS branch chains is connected with the aircraft part through the spherical hinge, the other end is connected witha revolute pair sliding block through a revolute pair, the revolute pair sliding block and an upper guide rail from a sliding pair, the upper guide rail and a lower guide rail form a sliding pair, and the lower guide rail is fixed on the quiet platform. The laser tracking system comprises a laser tracker and enclosures thereof. The system adjusting method comprises seven steps. The invention realizes arbitrary adjustment of space of parts to be assembled, employs laser detection, and ensures assembling accuracy.

Description

(1) Technical field [0001] The invention relates to an aircraft component attitude adjustment assembly system and a debugging method based on a six-degree-of-freedom parallel mechanism, and belongs to the technical field of aircraft component assembly. (2) Technical background [0002] At present, my country's aircraft assembly still uses the assembly technology of the former Soviet Union in the 1960s and 1970s. This working method has a long manufacturing cycle, many assembly coordination links, and the coordination process technology is complicated. In particular, when large parts are docked and assembled, the two parts are placed on the bracket or trailer platform respectively. There is usually a circle of connecting holes and connecting pins on the docking ring surface. Push one part slowly close to the other part, and observe the adjustment of the connecting hole. Insert after aligning with the pin. This method makes the matching accuracy of the hole pins on the butt j...
