Description

Technical Field

[0001] The utility model belongs to the technical field of aviation manufacturing and assembly, and relates to a fast and accurate lead-in device for a T-shaped structure. Background Art

[0002] The T-shaped structure is a commonly used structural form on aircraft. Aircraft structural beams, columns, T-shaped corner pieces, etc. are all T-shaped structures. For specific forms, please refer to the attached Figure 1 .

[0003] In existing operations, there are two main ways to draw the center line of the profile ribs: before assembly; the operator first uses a steel ruler to measure the width of one side of the T profile, then measures the thickness of the ribs and calculates the size from one side of the T profile to the center line of the ribs, and finally uses a steel ruler to measure the center line of the profile according to one side of the profile edge; after assembly, the operator first uses a steel ruler to measure the size of the rivet hole center on the profile from the T profile ribs, then measures the thickness of the two T profile ribs, then calculates the distance from the rivet hole center to the center line, and finally measures the center line of the T profile through the rivet hole center. The above two measurement methods have complicated steps. As a common structural form, both methods are used to draw the center line, which is inefficient, affects the production cycle, and reduces production capacity. At the same time, the accuracy of the center line position after measurement and calculation is not high, which affects product quality. Utility Model Content
