Description

Technical Field

[0001] The present application relates to the technical field of wing coating, and in particular to a wing coating tool. Background Art

[0002] The wing of an aircraft is a wing-shaped object installed on the side of the aircraft, which is used to provide lift for the aircraft body. After the wing is formed (rough part) or when it is returned to the factory for maintenance after a period of use, there will be some defects in the wing, such as small burrs or cracks.

[0003] As one of the steps in repairing wing defects, the application of putty is generally carried out by manually applying putty on the wing surface with a handheld scraper to repair the wing defects. In this process, the strength of the force applied to the wing surface cannot be guaranteed, which may result in some burrs not being eliminated, and the range of the force applied to the wing surface cannot be guaranteed, which may result in some cracks not being filled. For certain aircraft models, if these defects are not eliminated or reduced to a safe range, there will be serious safety hazards. Utility Model Content

[0004] The present application aims to at least solve the technical problem in the prior art that the strength and range of the force applied to the wing surface cannot be guaranteed, resulting in the inability to eliminate or reduce wing defects within a safe range. To this end, the present application proposes a wing coating tool.

[0005] The present application provides a wing coating tool, comprising:

[0006] A base, wherein a guide rail is provided on the base;

[0007] A clamping member, the clamping member is mounted on the base and is used to clamp and fix the wing;

[0008] A coating component is slidably connected to the guide rail, and has a receiving hole for cooperating with the wing. A grinding sheet is provided in the receiving hole, and the grinding sheet is used to be clamped between the hole wall of the receiving hole and the wing.

[0009] By adopting the above technical solution, the wing can be first placed in the accommodating hole, and the outer wall of the wing can be in contact with the polishing sheet. The wing is then clamped and fixed by the clamping member, and finally the coating member is made to slide along the guide rail. In the process of the coating member sliding along the guide rail, the polishing sheet applies force evenly to the surface of the wing. On the one hand, the putty pre-coated on the wing can be dispersed to the entire surface of the wing to fill the crack defects on the surface of the wing. On the other hand, it can also achieve the effect of polishing the surface of the wing and eliminate the burrs on the surface of the wing, thereby achieving the purpose of eliminating these defects or reducing them to a safe range.

[0010] According to one embodiment of the present application, the coating member includes a moving seat and a first scraper;

[0011] The movable seat is slidably connected to the guide rail, and the movable seat is detachably connected to the first scraper via a connecting column, and the accommodating hole is formed between the movable seat and the first scraper.

[0012] By adopting the above technical solution, the coating component is connected to the first scraper separately through the movable seat. Compared with the integrally formed coating component, it is easier to install the wing in the accommodating hole and it is also easier to clamp the grinding sheet between the hole wall of the accommodating hole and the wing.

[0013] According to one embodiment of the present application, a cushion block is crimped between the first scraper and the movable seat.

[0014] By adopting the above technical solution, the first scraper is directly pressed onto the pad without increasing or reducing the squeezing force on the wing, thereby avoiding damage to the contact area between the wing and the first scraper. In addition, the accommodating hole formed between the first scraper and the second scraper is enlarged, thereby improving the adaptability to accommodating the wing.

[0015] According to an embodiment of the present application, a nut is threadedly connected to one end of the connecting column away from the movable seat, and a compressed first elastic sheet is provided between the nut and the first scraper.

[0016] By adopting the above technical solution, such a design can roughly judge the extrusion pressure of the first scraper on the wing by the deformation degree of the first elastic sheet, so as to avoid excessive extrusion pressure of the first scraper on the wing, causing damage to the contact area between the wing and the first scraper.

[0017] According to one embodiment of the present application, the movable seat comprises a seat body and a second scraper;

[0018] The seat body is slidably connected to the guide rail, and the seat body is connected to the connecting column. The connecting column is sleeved with the second scraper, a compressed second elastic sheet is provided between the second scraper and the seat body, and the accommodating hole is formed between the second scraper and the first scraper.

[0019] By adopting the above technical solution, such a design can roughly judge the extrusion force of the first scraper on the wing by the deformation degree of the first elastic sheet and the second elastic sheet, so as to further avoid excessive extrusion force of the first scraper on the wing.

[0020] According to an embodiment of the present application, the guide rails are disposed on both sides of the accommodating hole, and a gap is provided between the seat body and the base.

[0021] By adopting the above technical solution, it is possible to avoid friction between the seat body and the base, thereby preventing the seat body from moving.

[0022] According to one embodiment of the present application, a handrail is installed on the coating component.

[0023] By adopting the above technical solution, it is convenient to manually apply a force to the seat body along the track direction.

[0024] According to one embodiment of the present application, the clamping member includes a first clamping plate, a second clamping plate and a driving seat;

[0025] The first clamping plate and the driving seat are both installed on the base. The driving seat is transmission-connected with the second clamping plate to drive the second clamping plate to approach or move away from the first clamping plate. The second clamping plate and the first clamping plate are used to abut against the wing.

[0026] According to one embodiment of the present application, the first clamping plate has a positioning shaft on the side facing the second clamping plate, and the positioning shaft is used to be inserted into one end of the wing. The second clamping plate has a limiting groove on the side facing the first clamping plate, and the limiting groove is engaged with the other end of the wing.

[0031] 1. The wing can be placed into the receiving hole first, and the outer wall of the wing contacts the polishing sheet. Then the wing is clamped and fixed by the clamping member. Finally, the coating member slides along the guide rail. During the sliding of the coating member along the guide rail, the polishing sheet applies force evenly to the surface of the wing. On the one hand, the putty pre-coated on the wing can be dispersed to the entire surface of the wing to fill the crack defects on the surface of the wing. On the other hand, it can also achieve the effect of polishing the surface of the wing and eliminate the burrs on the surface of the wing, thereby achieving the purpose of eliminating these defects or reducing them within a safe range.

[0046] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0047] Reference below Figure 1-Figure 6A wing coating jig according to an embodiment of the present application is described.

[0048] like Figure 1 and Figure 2 As shown, the wing coating jig includes a base 100 , a clamping member 200 and a coating member 300 .

[0049] A guide rail 110 is disposed on the base 100 . The guide rail 110 may be one or a plurality of guide rails 110 disposed in parallel.

[0050] The clamping member 200 is installed on the base 100 and is used to clamp and fix the wing.

[0051] The coating component 300 is slidably connected to the guide rail 110, and has a receiving hole a for cooperating with the wing. A grinding sheet is provided in the receiving hole a, and the grinding sheet is used to be clamped between the hole wall of the receiving hole a and the wing. The grinding sheet can be selected from 120-mesh sandpaper or 320-mesh sandpaper, etc., and this embodiment is not limited.

[0052] In this embodiment, the wing can be first placed in the accommodating hole a, and the outer wall of the wing is in contact with the polishing sheet, and then the wing is clamped and fixed by the clamping member 200, and finally the coating member 300 is made to slide along the guide rail 110. In the process of the coating member 300 sliding along the guide rail 110, the polishing sheet applies force evenly to the surface of the wing. On the one hand, the putty pre-coated on the wing can be dispersed to the entire surface of the wing to fill the crack defects on the surface of the wing. On the other hand, it can also achieve the effect of polishing the surface of the wing and eliminate the burrs on the surface of the wing, thereby achieving the purpose of eliminating these defects or reducing them within a safe range.

[0053] like Figure 3 As shown, in some embodiments, the coating member 300 includes a moving seat 310 and a first scraper 320 .

[0054] The moving seat 310 is slidably connected to the guide rail 110 . The moving seat 310 is detachably connected to the first scraper 320 via a connecting column 311 . An accommodating hole a is formed between the moving seat 310 and the first scraper 320 .

[0055] The coating component 300 of this embodiment is separately connected via the movable seat 310 and the first scraper 320. Compared with the coating component 300 formed in one piece, it is easier to install the wing in the accommodating hole a and to clamp the grinding sheet between the hole wall of the accommodating hole a and the wing.

[0056] In actual implementation, a notch is provided on the hole wall of the accommodating hole a, and the notch is used to accommodate the adhesive bonding polishing sheet.

[0057] like Figure 3As shown, in some embodiments, a nut 312 is threadedly connected to one end of the connecting column 311 away from the moving seat 310 , and a compressed first elastic sheet 410 is provided between the nut 312 and the first scraper 320 .

[0058] This design can roughly determine the squeezing force of the first scraper 320 on the wing by the deformation degree of the first elastic sheet 410, so as to avoid excessive squeezing force of the first scraper 320 on the wing, thereby preventing damage to the contact area between the wing and the first scraper 320.

[0059] like Figure 4 As shown, in some embodiments, the moving seat 310 includes a seat body 313 and a second scraper 314 .

[0060] The seat body 313 is slidably connected to the guide rail 110 , and the seat body 313 is connected to the connecting column 311 , a second scraper 314 is sleeved on the connecting column 311 , a compressed second elastic sheet 420 is provided between the second scraper 314 and the seat body 313 , and a receiving hole a is formed between the first scraper 320 and the second scraper 314 .

[0061] Such a design can roughly determine the squeezing force of the first scraper 320 on the wing by the deformation degree of the first elastic sheet 410 and the second elastic sheet 420, so as to further avoid excessive squeezing force of the first scraper 320 on the wing.

[0062] In actual implementation, the first elastic sheet 410 and the second elastic sheet 420 may be springs.

[0063] like Figure 3 and Figure 4 As shown, in some embodiments, a spacer block 330 is pressed between the first scraper 320 and the second scraper 314 .

[0064] In this embodiment, the first scraper 320 is directly pressed onto the pad 330 without increasing or reducing the squeezing force on the wing, thereby avoiding damage to the contact area between the wing and the first scraper 320. In addition, the accommodating hole a formed between the first scraper 320 and the second scraper 314 is enlarged, thereby improving the adaptability to accommodating the wing.

[0065] like Figure 1 As shown, in some embodiments, the guide rails 110 are disposed on both sides of the receiving hole a, and there is a gap between the seat body 313 and the base 100. This can avoid the friction between the seat body 313 and the base 100, which hinders the movement of the seat body 313.

[0066] like Figure 4 As shown, in some embodiments, a handrail 3131 is installed on the seat body 313. This makes it easy to manually apply a force to the seat body 313 along the track direction.

[0067] like Figure 2 and Figure 5 As shown, in some embodiments, the clamping member 200 includes a first clamping plate 210 , a second clamping plate 220 and a driving seat 230 .

[0068] The first clamping plate 210 and the driving seat 230 are both installed on the base 100. The driving seat 230 is transmission-connected with the second clamping plate 220 to drive the second clamping plate 220 to approach or move away from the first clamping plate 210. The second clamping plate 220 and the first clamping plate 210 are used to abut against the wing.

[0069] The driving seat 230 can electrically drive the second clamping plate 220 . For example, the driving seat 230 is an electric push rod, which is power-coupled with the second clamping plate 220 to move it closer to or farther from the first clamping plate 210 .

[0070] The driving seat 230 can also be used to manually drive the second clamping plate 220. For example, the driving seat 230 includes a base, a telescopic rod and a turntable. One end of the telescopic rod is threaded through the base and fixedly connected to the second clamping plate 220. The other end of the telescopic rod is axially installed on the turntable. The rotation of the turntable can drive the telescopic rod to realize the second clamping plate 220 approaching or moving away from the first clamping plate 210.

[0071] like Figure 6 As shown, the first clamping plate 210 has a positioning shaft 211 on one side facing the second clamping plate 220, and the positioning shaft 211 is used to be inserted into one end of the wing.

[0072] like Figure 5 As shown, the second clamping plate 220 has a limiting groove 221 on one side facing the first clamping plate 210 , and the limiting groove 221 is engaged with the other end of the wing.

[0073] This design is used to improve the clamping stability of the first clamping plate 210 and the second clamping plate 220 on the wing.

[0074] It should be noted that in this embodiment, the structure of the driving seat 230 can be simplified, that is, the driving seat 230 includes a base and a telescopic rod, one end of the telescopic rod slides through the base and is fixedly connected to the second clamping plate 220. In this way, only the telescopic rod needs to be pushed to achieve the purpose of moving the second clamping plate 220 toward the first clamping plate 210 and the limiting groove 221 of the second clamping plate 220 is engaged with the other end of the wing.

[0075] In actual implementation, the second clamping plate 220 is a wooden clamping plate, which is used to prevent the second clamping plate 220 from having a hard contact with the wing.

[0076] The following describes the embodiments of the present application in detail from a different implementation perspective.

[0077] The second scraper 314 is sleeved on the connecting column 311 of the base 313 so that the second elastic sheet 420 between the second scraper 314 and the base 313 is compressed.

[0078] Glue 120-grit sandpaper on the opposite sides of the first scraper 320 and the second scraper 314.

[0079] The first scraper 320 is mounted on the connecting column 311 through a nut, so that the first elastic sheet 410 between the nut 312 and the first scraper 320 is compressed, and the first scraper 320 and the second scraper 314 sandwich a wing.

[0080] The second clamping plate 220 is driven by the driving seat 230 to cooperate with the first clamping plate 210 to clamp the left and right ends of the wing.

[0081] Apply force along the track direction, push and pull the handrail 3131 back and forth, so that the putty pre-coated on the wing is dispersed to the entire surface of the wing, and the pushing and pulling process is continued for about 15 times.

[0082] Remove the 120-grit sandpaper glued to the opposite sides of the first scraper 320 and the second scraper 314, and replace it with 320-grit sandpaper, continue to apply force along the track direction, push and pull the handrail 3131 back and forth, and the pushing and pulling process continues for about 20 times.

[0083] It should be noted that 320-grit sandpaper can be used directly in the first push-pull process, which can save the step of changing sandpaper and improve efficiency, but the number of push-pull processes also needs to be adjusted accordingly.

[0084] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
