Description

Technical Field

[0001] The utility model relates to the technical field of hole drawing, in particular to a hole drawing tool for an aircraft mouth cover. Background Art

[0002] In aircraft manufacturing, there are many types of covers (maintenance covers, equipment) on aircraft, rockets and other aircraft. In the process of repeated disassembly and assembly, it is inevitable that the covers will be damaged and need to be replaced with new spare parts. At this time, if the cover does not have a corresponding drilling template, it is necessary to manually adapt the new cover to the frame and make counter holes.

[0003] Due to the different shapes of the mouth covers, it is necessary to manually draw lines and arrange points for drilling; the traditional reverse hole making method is to draw lines on the machine body near the mouth frame according to the holes on the mouth frame, reverse the hole positions to the mouth frame according to the lines on the machine body, and then make holes on the mouth cover; or use a traditional hole guide to guide holes. The above two methods are inefficient and have poor hole making accuracy, which seriously affects the production cycle and hole making quality of the product.

[0004] With the improvement of manufacturing technology, the requirements for hole making accuracy and positioning are becoming more and more stringent, and the production cycle is constantly shortened. Under this circumstance, we urgently need a tool that can improve the efficiency of reverse hole making and ensure the accuracy of hole making. Utility Model Content

[0006] To this end, the technical solution of the utility model is: a hole-guiding tool for an aircraft cover, which works in conjunction with a support plate nut on a body cover; it includes a scored cone, a sealing tape and a strong magnet, the sealing tape being pasted under the screw hole of the support plate nut; the scored cone is placed in the screw hole with the scored part facing upwards; the scored cone is made of magnetic material, and the strong magnet can drive the scored cone to move upward in the screw hole through magnetic attraction.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the scored cone includes a cylindrical body, and the top of the cylindrical body is a conical scored portion.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the outer diameter of the cylindrical body matches the inner diameter of the screw hole of the support plate nut, and the two are coaxially arranged.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the middle of the engraved part is a sharp point, the sharp point is located on the central axis of the screw hole, and its movement trajectory under the action of the magnetic attraction force is located on the central axis of the screw hole.

[0010] On the basis of the above scheme and as a preferred scheme of the above scheme: the length of the scored cone is less than the depth of the screw hole of the support plate nut, that is, the scored part of the scored cone is lower than the upper opening of the screw hole.

[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the sealing tape seals the bottom end of the screw hole, and the scored cone is located above the sealing tape.

[0012] When using,

[0013] 1) Remove the old cover, and the original support plate nut is still fixed on the body frame;

[0014] 2) Use sealing tape to stick it under the screw hole of the support plate nut, so that the sealing tape can seal the bottom of the screw hole to form a semi-enclosed space for placing the scored cone;

[0015] 3) According to the size of the screw hole, select a scoring cone of appropriate specifications and place the scoring cone in the screw hole with the scoring part of the scoring cone facing the side where the cover is to be installed;

[0016] 4) Place the repaired mouth cover on the mouth frame and adjust the position;

[0017] 5) Place a strong magnet on the mouth frame and shake it. Use the magnetism of the magnet to attract the scored cone through the mouth cover. The scored cone moves vertically upward along the screw hole, and the scored part leaves scratches on the mouth cover.

[0018] 6) Remove the cover and make a hole by scratching.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows: using strong magnets, scored cones, and adhesive tape, hole-drawing operations can be performed on the existing hole frames and the corresponding mouth covers of various aerospace vehicle bodies; to draw holes on the original support plate nuts, it is only necessary to seal with adhesive tape, insert the scored cone, and use the magnet to drive the scored cone to leave a mark, and the operation is very convenient; it is suitable for hole-drawing operations at different positions, has a wide range of adaptability, and can significantly improve production efficiency and reverse hole accuracy.
