Problems solved by technology

[0002] In the joint positioning of the existing aircraft assembly, after assembly, the installation position of these joints and the axis position of the joint hole are difficult to detect, and it is difficult to judge the assembly result, so it is difficult to find possible assembly errors, which will increase the matching of the finished product. Difficulty in installation, even resulting in the failure of the finished product to be installed, which increases the risk of aircraft assembly and reduces the reliability of the aircraft

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with specific embodiments.

[0024] See also figure 1 , figure 2 and image 3 ,in, figure 1 It is a schematic diagram of the tool for detecting the axis of the hole position of the joint after assembly. figure 2 yes figure 1 A-A sectional view of, image 3 It is a diagram of the analysis method of the center point of the joint hole and the axis error after assembly. The axis detection tool of the present invention is a shaft 1, and the main precision requirements of the shaft 1 are that the coaxiality relative to the reference A is 0.05 mm, and the symmetry is 0.05 mm (for details, please refer to figure 1 , figure 2 Tolerance mark in ), the lower end of the shaft 1 has a shoulder 6 that fits with the end face of the bush 2, and is precisely matched with the inner hole of the bush 2 of the assembly joint 3. Two symmetrical planes 4 are processed on the upper part of the shaft 1 cen...

Abstract

The invention belongs to the airplane assembly technology, relates to a tool and a method for detecting assembly error of center points of end faces of joint holes and assembly error of joint hole axes during airplane assembly, and particularly relates to a hole axis detection tool and a detection method thereof. The hole axis detection tool is a shaft, the lower end of the shaft is matched with an assembling join hole, the upper portion of the shaft is provided with two planes machined by utilizing the plane of the axis as a symmetry plane, two through holes are manufactured on the two planes vertically, and center lines of the through holes are intersected with the axis of the shaft. The method includes steps of mounting the shaft in a joint bushing hole of an assembled product during use; measuring coordinates of points 1, 2, 3 and 4 respectively; computing coordinates of center points A and B according to the coordinates of points 1,2,3 and 4; drawing the actual axis, running through the center points A and B, of the joint hole; comparing and analyzing the actual axis of the joint hole and the theoretical axis; accurately analyzing assembly error of the center point of the end face of the joint hole and the hole axis after assembling; and finally taking measures to guarantee assembly accuracy of joints so that quality of products is guaranteed.

Description

technical field [0001] The invention belongs to the aircraft assembly technology, and relates to a detection tool for the position of an aircraft assembly joint and the axis of a joint hole and a detection method thereof. Background technique [0002] In the joint positioning of the existing aircraft assembly, after assembly, the installation position of these joints and the axis position of the joint hole are difficult to detect, and it is difficult to judge the assembly result, so it is difficult to find possible assembly errors, which will increase the matching of the finished product. The installation is difficult, and even the finished product cannot be installed, which increases the risk of aircraft assembly and reduces the reliability of the aircraft. Contents of the invention [0003] The object of the present invention is to provide a hole position axis detection tool with simple structure and convenient detection. [0004] In addition, the present invention also...
