Embodiment Construction
[0015] Referring to the accompanying drawings, the aircraft assembly positioning method based on three-dimensional laser projection is to input the design digital model of the first assembly part 4 and the second assembly part 5 into the control computer 1 of the projection device 2 to establish a simulated assembly relationship. In the coordinate system of the first assembly part 4, the three-dimensional outline of the second assembly part 5 or the center of the fastener hole is projected on the assembly position of the first assembly part 4 in the form of a laser line, instead of the tooling locator, the drilling The model, instead of the line drawing positioning method, completes part positioning, fastener hole position determination and assembly inspection.
[0016] After collecting the feature points on the entity of the first assembly 4 and correlating with the design digital model of the first assembly 4, the projection device 2 is connected to the aircraft coordinate sy...
