Description

Technical Field

[0001] The utility model belongs to the technical field of aircraft assembly, and in particular relates to a marking and hole making tool used for drilling hanging holes on a wall plate of an aircraft wing. Background Art

[0002] At the aircraft assembly site, the design was changed. Starting from a certain type of aircraft, the mooring joints were installed at the hanging holes on the leading edges of the middle and outer wings. When installing the mooring joints, it was found that the hole spacing of the hanging holes and the hole spacing of the mooring joints were quite different, and it could not be installed. At the same time, it was difficult to accurately make holes through wires on site, causing this problem to occur on more than a dozen aircraft in a row. It seriously affected the installation of the mooring joints and the delivery of aircraft.

[0003] After investigation, it was found that the actual hanging hole was a U-shaped hole. The precision requirement for the hole during installation was not high, and the hole spacing requirement was not very precise. At the same time, the hanging hole drilling process required manual wire drawing and line drawing. There was a certain amount of error accumulation during the drilling process, which was unavoidable, resulting in the inability to accurately guarantee the hole spacing. Therefore, the mooring joint with high precision requirements could not be installed. This problem has been plaguing on-site assembly. Utility Model Content

[0004] Purpose of the utility model: To solve the problems existing in the prior art, a marking and hole-making tool is provided for drilling hanging holes on the wall panels of aircraft wings.

[0005] Technical solution:

[0006] A marking and hole-making tool is used for drilling hanging holes in the upper wall panel of an aircraft wing, comprising a drilling template, a drill sleeve and a marking tool, wherein the marking tool comprises a Z-shaped clamping portion and an I-shaped marking portion arranged on the upper surface of the Z-shaped clamping portion, a gap is arranged between the Z-shaped clamping portion and the I-shaped marking portion, the front edge of the upper wall panel of the wing is clamped in the gap, and the corner box edge of the lower part of the upper wall panel of the wing is clamped on the inner side of the Z-shaped clamping portion, and the drilling template and the drill sleeve are arranged on the upper surface of the I-shaped marking portion.

[0007] Furthermore, a drill sleeve hole is arranged on the drilling template, and the drill sleeve is arranged in the drill sleeve hole.

[0008] Furthermore, the Z-shaped clamping portion is riveted to the I-shaped marking portion.

[0009] Furthermore, the Z-shaped clamping part includes a main body and protruding parts at both ends, and the protruding parts at both ends are respectively located on both sides of the main body. The inner side surface of the protruding part is used to clamp with the edge of the lower corner box of the wing upper wall panel to achieve equivalent conversion.

[0010] Furthermore, the I-shaped marking portion is provided with marking grooves on both sides, the bottom angle of the marking groove is consistent with the posture of the aircraft wing, and the two outer sides of the marking groove are parallel to the inner sides of the extension portion located on the same side of the Z-shaped clamping portion.

[0011] Furthermore, the distance between the two side edges of the scribe groove is the distance between two hanging holes to be precisely drilled.

[0012] Beneficial effects:

[0013] Compared with the prior art, the beneficial effects (advantages) of the utility model are:

[0014] 1. When marking and drilling the hanging holes, the I-shaped marking part and the edge of the upper wall plate can be fit and clamped by using the tool, and the Z-shaped clamping part can be used to clamp the edge of the corner box to achieve equivalent conversion. By using equivalent substitution, the position of the corner box below the upper wall plate is converted to the plane of the upper wall plate. The tool is directly used to replace the lead-in process that causes the error. The marking tool is used to directly mark the center line position of the hanging hole on the upper wall plate surface, and then accurate drilling is performed by combining with a drilling jig, which directly avoids the error and achieves the process of precise hole making. Compared with the previous operation method, the lead-in process is subtracted, and the drawing process is reduced once, so that the error is controlled during the drawing process and the purpose of precise hole making is achieved.

[0015] 2. By combining the tool of the utility model with the drilling jig, the work efficiency is effectively improved in the process of drilling the hanging holes, replacing the repeated marking process with multiple errors, and realizing efficient hole making. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model overcomes the existing problems of large line drawing and hole making errors, large line lead-in method errors, and difficulty in ensuring hole spacing, and converts the indirect line lead-in process between two planes into a direct line drawing process in the same plane by an equivalent conversion method. At the same time, with the help of this tool, multiple line drawing processes are reduced to one, further reducing line drawing errors, improving hole making efficiency, and providing a strong guarantee for subsequent line drawing and hole making and installation of mooring joints.

[0021] The tool combines a drilling template 4, a drill sleeve 3 and a marking tool to ensure the accuracy of the hole distance and the correctness of the installation position from the two aspects of marking and drilling. First, in order to effectively ensure the hole distance, a special drilling template 4 and a drill sleeve 3 are set. By using the drilling template 4 and the drill sleeve 3, the hole distance and the hole diameter are guaranteed to be qualified; second, starting from the drawing error, through independent innovative design, the lead and drawing process are improved. By designing a new special marking tool, the indirect lead process between two planes is transformed into a direct drawing process in the same plane, which directly avoids the lead error and marking error, thereby achieving accurate hole making.

[0022] The working principle of this new special tool is that during the assembly process, the Z-shaped clamping part 1 of the marking tool is directly clamped at the edge of the corner box below the upper wall panel surface of the aircraft wing (the tool is adaptable), so that the bottom edge of the marking groove of the I-shaped marking part 2 of the marking tool and the edge of the upper wall panel fit and clamp, and the indirect lead marking and hole making process between the two planes of the wall panel surface and the corner box surface is converted into the marking and hole making process in the same plane by equivalent conversion, that is, accurate marking and hole making is performed on the upper wall panel surface, and the two outer side lines of the marking groove in the marking tool are the center line position of the hanging hole, combined with the wall panel edge size requirements, the center position of the hole is accurately found. Then use the drilling template to accurately and precisely drill the hole position, accurately ensure the accuracy, and meet the drawings and actual needs.

[0023] Therefore, the utility model proposes a marking and hole-making tool for drilling hanging holes in the upper wall panel of an aircraft wing, which specifically includes a drilling template 4, a drill sleeve 3 and a marking tool, wherein the marking tool includes a Z-shaped clamping portion 1 and an I-shaped marking portion 2 arranged on the upper surface of the Z-shaped clamping portion 1, a gap is arranged between the Z-shaped clamping portion 1 and the I-shaped marking portion 2, the upper wall panel of the wing is clamped in the gap, and the corner box edge of the lower part of the upper wall panel of the wing is clamped on the inner side of the Z-shaped clamping portion 1, and the drilling template 4 and the drill sleeve 3 are arranged on the upper surface of the I-shaped marking portion 2 of the marking tool.

[0024] In this embodiment, a drill sleeve hole is provided on the drilling template 4, and the drill sleeve 3 is arranged in the drill sleeve hole.

The inner side surface of the protruding portion is used to clamp with the edge of the lower corner box of the wing upper wall panel to achieve equivalent conversion.

[0027] In this embodiment, marking grooves are provided on both sides of the I-shaped marking line 2. The marking grooves are provided along the edges on both sides of the I-shaped marking line 2 to form two approximately "C" shapes in opposite directions, including a bottom edge in the middle and outer edges at both ends of the bottom edge. The angle of the bottom edge of the marking groove is consistent with the posture of the aircraft wing, and the two outer edges of the marking groove are parallel to the inner side edges of the extension portion on the same side of the Z-shaped clamping portion 1.

[0028] In this embodiment, the distance between the two side edges of the scribe groove is the distance between two hanging holes to be precisely drilled.

[0029] Please see attached Figure 3 It is shown that it is the process of drilling hanging holes at the 4 ribs at the front edge of a certain type of machine. At this time, the Z-shaped clamping part 1 of the marking tool is directly clamped at the edge of the corner box below the upper wall panel surface (the tool is adaptable), so that the bottom edge of the marking groove of the I-shaped marking part 2 of the marking tool and the edge of the upper wall panel fit and clamp, and the indirect lead marking and hole making process between the two planes of the wall panel surface and the corner box surface is transformed into the marking and hole making process in the same plane by equivalent conversion, that is, accurate marking and hole making are performed on the upper wall panel surface. The two outer side lines of the marking groove in the marking tool are the center line position of the hanging hole. Combined with the requirements of the wall panel edge size, the center position of the hole is accurately found. Then use the drilling template to accurately and precisely drill the hole position, accurately ensure the accuracy, and construct efficiently at the same time.
