Description

A method of drilling holes suitable for stack structure in closed-angle area

technical field

The present application relates to the technical field of aircraft assembly, and in particular, to a hole guiding method suitable for closed-angle holes in a single-sided closed area of a laminated structure.

Background technique

In the field of aircraft assembly, it is usually necessary to make holes on the surface of the closed corner area of the T-shaped corner piece because there is no construction space for making holes in the laminated structure of the closed-angle T-shaped corner piece. First use a pencil to mark the edge position of the hole, then use a steel ruler to lead the line of the hole position on the surface of the T-shaped piece to the lower surface, and finally make the hole from the open area of the lower surface. At present, right-angle pneumatic drills and eccentric pneumatic drills are generally used for hole-making tools in the closed-angle area. There are different types due to different use requirements and application occasions to meet different hole-making needs. However, the structure of some areas is complex, and the limitation of space makes the operability of the hole-making environment worse. The hole-making tool cannot meet the hole-making requirements in the closed-angle area, and there is no room for operation and construction, so it is necessary to scribe the hole. To the lower surface, in this process, due to the visual error and the error of the steel ruler, the hole position deviates, so that the hole position on the upper and lower surfaces is not concentric, thus affecting the quality and efficiency of the subsequent hole making, so a The specially made hole guide and hole guide method are used to complete the hole guide work of the laminated structure in the space closed-angle area.

SUMMARY OF THE INVENTION

In order to solve the above problems, the purpose of the present application is to provide a hole guiding method suitable for the stacked structure in the closed-angle area.

A hole guide method suitable for a laminated structure in a closed-angle area, the closed-angle area is the closed-angle area of a corner sheet fixed above the laminated structure, and the method is to use a hole guide to draw the upper and lower surfaces of the laminated structure. The hole position of the hole to be made is drawn, and the reverse hole making is carried out from the bottom of the laminated structure. The hole guide structure includes a guide rod, a fixed measuring block, and a sliding measuring block. The fixed measuring block is fixed at the front end of the guide rod and is perpendicular to the guide rod. It can be slid along the guide rod, and the sliding measuring block is provided with a scale line that is exactly the same as the fixed measuring block.

The drilling steps are as follows:

1. Draw the hole position of the initial hole for the required hole in the closed-angle area of the surface corner sheet on the laminated structure;

2. Stick the lower surface of the fixed measuring block to the closed-angle area of the corner piece, and align the scale line of the fixed measuring block with the drawn hole position;

3. Push the sliding measuring block upward along the guide rod until the upper surface of the sliding measuring block is attached to the bottom of the laminated structure;

4. Read the scale line data on the surface of the fixed measuring block, read the data on the scale of the sliding measuring block according to the data of the fixed measuring block, and draw the hole position under the laminated structure according to the data;

5. According to the marked hole positions, make holes from the bottom of the laminated structure along the normal direction of the laminated structure in the reverse direction.

The hole guiding method is suitable for the laminated structure in the closed-angle area, and the hole-guiding operation of the hole-guiding device has good applicability. Affecting the construction situation, the method is easy to use and easy to operate, thereby improving the accuracy of hole positions in the assembly area and improving the assembly efficiency on the assembly site.

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Detailed ways

In aircraft construction, the closed-angle edge region is the closed-angle region of the corner piece fixed above the laminate structure. As shown in Figure 1, the hole guide includes a guide rod 1, a fixed measuring block 2, a sliding measuring block 3, and a scale line 4 on the measuring block. The fixed measuring block 2 is fixed at the front end of the guide rod 1, and is connected with the guide rod 1 Vertical, there is a scale line 4 on the fixed measuring block 3, the sliding measuring block 3 is vertically penetrated on the guide rod 1 and can slide along the guide rod 1, and the sliding measuring block 3 is provided with a scale line 4 that is completely consistent with the fixed measuring block 2 .

As shown in Figure 2, the method of using the hole guide to guide holes, the operation process is as follows:

1. In the closed-angle area of the corner piece, mark the hole position of the initial hole for the required hole;

2. Stick the lower surface of the fixed measuring block 2 against the closed-angle area of the corner piece, and align the scale line of the fixed measuring block 2 with the drawn hole position;

3. Push the sliding measuring block 3 upward along the guide rod 1 until the upper surface of the sliding measuring block 3 is attached to the bottom of the laminated structure;

4. Read the scale line data on the surface of the fixed measuring block 2, read the data on the scale 4 of the sliding measuring block 3 according to the data of the fixed measuring block 2, and draw a hole position under the laminated structure according to the data ;

5. According to the marked hole positions, make holes in the reverse direction along the normal direction of the laminated structure from below the laminated structure.

The method can solve the problems of inaccurate hole position, hole-making deviation, and poor operability caused by poor area openness in actual operation.
