Embodiment Construction

[0034] See figure 1 , the wing web type rib is straight at the top and has a The two sides are double-arc-shaped metal plates, and there are four large holes and three small holes on it. The three small holes are positioning reference holes. They are distributed in a right triangle, and the diameter of the holes is selected To ensure the strength requirements of the wing rib. The rib is attached to the wing's stringers and skin, which are assembled after the rib is assembled.

[0035] The concretely implemented group of web-type ribs has 4 rib parts, respectively numbered rib 1#, rib 2#, rib 3# and rib 4#, and the theory of 3 positioning reference holes for each rib The design data are shown in Table 1. After checking the strength of each rib and the overall strength, the diameter of the positioning reference hole of this group of rib parts is selected as 6mm.

Abstract

The invention provides a method for assembling and locating web-type wing ribs on the basis of laser measurement. The method comprises the following steps: 1. mounting a drone base on the three reference holes of the wing rib; 2. fixing the wing rib onto the clamp of an assembling unit; 3. clamping the wing rib to the position of an assembling space by the assembling unit; 4. measuring the coordinates of the circle centers of the three reference holes on the wing rib by a laser; 5. calculating the deviation and compensation of the current spatial position of the wing rib; 6. generating the adjustment command according to the deviation and compensation of the spatial position calculated in step 5; 7. driving the assembling unit to carry out the micro-adjustment of the spatial position according to the adjustment command of the spatial position; 8. repeating the process from step 4 to step 7 until the deviation of the spatial position of the wing rib is allowable; and 9. repeating the process from step 1 to step 8, so as to complete the assembly of other wing ribs of the group. The invention can solve the problems that the existing analog-dependent method for assembling and locating the web-type wing rib in a dedicated assembling tool has the disadvantages of lower precision, lower efficiency and higher cost. Therefore, the invention has good application prospect in aircraft manufacturing.

Description

(1) Technical field: [0001] The invention relates to a method for assembling and positioning a wing web type wing rib based on laser measurement, and belongs to the technical field of assembling aircraft components in aviation manufacturing. (two) background technology: [0002] The rib is the basic component that forms the shape of the wing. The shape of the rib is manufactured according to the designed airfoil. The assembled set of ribs is a part of the skeleton, and its outer surface is the key to determine the aerodynamic shape of the skin. The assembly The accuracy of the airfoil directly affects the airfoil formed by its outer covering skin. Web ribs are the most commonly used rib structures in modern aircraft. [0003] The traditional assembly of the rib is carried out in a special assembly tool (frame) based on the transfer of analog quantities, and the spatial position of the rib parts is determined by the outer surface of the clamp on the frame. This assembly met...
