Description

Covering allowance scriber

Technical Field

The utility model relates to a setting-out instrument field specifically relates to an covering surplus scriber.

Background

When the movable hatch cover of a certain airplane is assembled, the position relation between the movable hatch cover and a front windshield and the position relation between the movable hatch cover and an upper inclined frame need to be coordinated, and the allowance of the hatch cover skin needs to be repaired. The method for repairing the skin allowance comprises the following steps: firstly, determining the allowance of the skin to be repaired according to the position relation between the skin and a front windshield and the upper inclined frame; taking points on the outer surface of the cabin cover skin in a segmented manner by taking the internal cabin cover framework as a reference, and connecting the points into a margin line; and finally, repairing and matching the skin allowance according to the allowance line. The method has the following defects:

a) the line drawing process is complicated, and the efficiency is lower

Because the movable hatch cover is of a semicircular structure, points are taken on the outer surface of the skin in a segmented mode by taking the internal skeleton as a reference, and the points are connected into a margin line. The method has the advantages of more points taken by sections, complex process and lower efficiency.

b) The repairing quality is not high

The sectional connecting points are connected into a broken line instead of a smooth curve, and large errors of point taking and line drawing exist in the sectional connecting line process, so that the edge of the skin after repair is not smooth, and the repair quality is not high. Due to the fact that the repair is not in place, the skin allowance is subjected to reworking for many times in the repair process.
