Description

Technical Field

[0001] This disclosure relates to the technical field of aircraft wing processing, and in particular to a positioning fixture for wing skin and a wing positioning processing device. Background Technology

[0002] To enable aircraft wings to withstand aerodynamic and inertial loads during flight, wing skin structures, such as those disclosed in Chinese patent document CN222663752U, are typically installed on the wing frame. However, since the skin structure needs to be riveted and fixed after being installed on the wing frame, and the surface of the skin structure is usually relatively smooth due to wind resistance design requirements, it is difficult to fix the position of the skin structure during the riveting process. If the skin structure is displaced relative to the wing frame, the fit between the skin structure and the wing frame will decrease, thereby reducing the support provided by the wing frame to the skin structure and ultimately leading to a decrease in the wing's load-bearing capacity. Utility Model Content

[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and to provide a positioning fixture and wing positioning processing device for wing skin that can reduce the displacement of the skin structure during the riveting process.

[0004] The purpose of this disclosure is achieved through the following technical solution:

[0005] A positioning fixture for wing skin, comprising:

[0006] A support base on which the wing frame is placed;

[0007] The positioning fixture for the wing skin also includes a positioning detection mechanism and at least three wing positioning mechanisms.

[0008] The positioning detection mechanism is installed on the support base and is used to detect the position of the skin structure; at least three wing positioning mechanisms are arranged sequentially along the length of the wing frame and are respectively fixedly connected to the support base; at least one wing positioning mechanism is used to press the first part of the skin structure onto the wing tip position of the wing frame, at least another wing positioning mechanism is used to press the second part of the skin structure onto the wing middle position of the wing frame, and at least one other wing positioning mechanism is used to press the third part of the skin structure onto the wing tail position of the wing frame, so that the skin structure fits onto the wing frame.

[0009] In some embodiments, each of the wing positioning mechanisms includes two wing-side pushing components, each of which is fixedly mounted on the support base; a wing clamping position is formed between the two corresponding wing-side pushing components, the wing clamping position being used to place the wing frame; the two corresponding wing-side pushing components are positioned opposite each other to jointly press the corresponding part of the skin structure against the corresponding position of the wing frame.

[0010] In some embodiments, the wing-side push assembly includes a fixed bracket, a push-pull driver, and a push rod; the fixed bracket is locked to the support base, the push-pull driver is fixedly disposed at the top of the fixed bracket, the first end of the push rod is connected to the power output end of the push-pull driver body, and the second end of the push rod faces the wing clamping position.

[0011] In some embodiments, the push-pull driver is a cylinder, and the first end of the push rod is fixedly connected to the piston rod of the cylinder.

[0012] In some embodiments, the wing-side push assembly further includes a guide assembly; the guide assembly is located on the moving path of the push rod and is fixedly connected to the support base; the guide assembly has a guide hole, and the second end of the push rod slides through the guide hole.

[0013] In some embodiments, the end face of the second end of the push rod is arc-shaped.

[0014] In some embodiments, the positioning detection mechanism includes two camera detection components, each of which is fixedly mounted on the support base; one of the camera detection components is respectively arranged on each side of the wing clamping position, and the lens of the camera detection component is used to face the wing frame.

[0015] In some embodiments, there are multiple positioning detection mechanisms, which are arranged sequentially along the length of the wing frame.

[0016] In some embodiments, the positioning detection mechanism further includes a lifting support disposed on the wing clamping position; the lifting support's extension rod is used to support and lift the wing frame.

[0017] A wing positioning and processing apparatus includes a wing skin positioning fixture according to any of the above embodiments.

[0018] Compared with the prior art, this disclosure has at least the following advantages:

[0019] The aforementioned positioning fixture for wing skin, with its positioning detection mechanism mounted on a support base, allows the positioning detection mechanism to determine the correct position of the skin structure when it is draped over the outer surface of the wing frame placed on the support base. Then, at least one wing positioning mechanism presses the first part of the skin structure onto the wingtip of the wing frame, and at least another wing positioning mechanism presses the skin structure onto the wing mid-section of the wing frame. Furthermore, at least one other wing positioning mechanism presses the third part of the skin structure onto the wingtip of the wing frame. Thus, at least three wing positioning mechanisms respectively fix the corresponding parts of the skin structure to their corresponding positions on the wing frame, ensuring the skin structure remains in close contact with the wing frame during riveting. The positioning detection mechanism also monitors in real-time whether the skin structure shifts during riveting, reducing the cumulative displacement between the skin structure and the wing frame and improving the overall quality of the wing.

[0032] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0036] Please see Figure 1One embodiment of the wing skin positioning fixture includes a support base 100, a positioning detection mechanism 300, and at least three wing positioning mechanisms 200. The support base 100 is used to place the wing frame. The positioning detection mechanism 300 is installed on the support base 100 and is used to detect the position of the skin structure. The at least three wing positioning mechanisms 200 are arranged sequentially along the length of the wing frame and are fixedly connected to the support base 100 respectively. At least one wing positioning mechanism 200 is used to press a first part of the skin structure at the wingtip position of the wing frame, at least another wing positioning mechanism 200 is used to press a second part of the skin structure at the wing center position of the wing frame, and at least one other wing positioning mechanism 200 is used to press a third part of the skin structure at the wing tail position of the wing frame, so that the skin structure fits onto the wing frame.

[0037] It is understandable that, since the positioning detection mechanism 300 is installed on the support base 100, when the skin structure is draped over the outer surface of the wing frame placed on the support base 100, the positioning detection mechanism 300 can obtain the position of the skin structure to determine whether the skin structure is in position. Then, at least one wing positioning mechanism 200 can press the first part of the skin structure to the wing tip position of the wing frame, and at least another wing positioning mechanism 200 can press the skin structure to the wing middle position of the wing frame. Furthermore, at least another wing positioning mechanism 200 can press the third part of the skin structure to the wing tail position of the wing frame. Thus, at least three wing positioning mechanisms 200 can fix the corresponding parts of the skin structure to the corresponding positions on the wing frame, thereby ensuring that the skin structure remains in close contact with the wing frame during the riveting process. Moreover, the positioning detection mechanism 300 can monitor in real time whether the skin structure is displaced during riveting, thereby reducing the cumulative displacement between the skin structure and the wing frame and improving the overall quality of the wing 10.

[0038] Please see Figure 2 In this embodiment, there are three wing positioning mechanisms 200: a wingtip positioning mechanism 211, a wing mid-section positioning mechanism 212, and a wingtip positioning mechanism 213. The wingtip positioning mechanism 211 is used to press the first part of the skin structure onto the wingtip position of the wing frame; the wing mid-section positioning mechanism 212 is used to press the second part of the skin structure onto the wing mid-section position of the wing frame; and the wingtip positioning mechanism 213 is used to press the third part of the skin structure onto the wingtip position of the wing frame, so that the skin structure fits snugly against the wing frame. It should be noted that the method by which the positioning detection mechanism 300 detects the position of the skin structure and the method by which the positioning detection mechanism 300 monitors in real time whether the skin structure is displaced during riveting are both prior art and not within the scope of this disclosure; therefore, they will not be elaborated here.

[0039] Please see Figure 2 and Figure 3 In some embodiments, each wing positioning mechanism 200 includes two wing-side pushing components 210, each wing-side pushing component 210 being fixedly mounted on the support base 100; a wing clamping position 110 is formed between the corresponding two wing-side pushing components 210, the wing clamping position 110 being used to place the wing frame; the corresponding two wing-side pushing components 210 are positioned opposite each other to jointly press the corresponding part of the skin structure against the corresponding position of the wing frame. It can be understood that after the wing frame placed on the wing clamping position 110 is covered with the skin structure, the wing-side pushing components 210 located on both sides of the wing clamping position 110 can respectively abut against the corresponding part of the skin structure against the corresponding position of the wing frame, so that the two wing-side pushing components 210 in the wing positioning mechanism 200 can jointly clamp and fix the wing frame to the support base 100.

[0040] Please see Figure 3 In some embodiments, the wing-side push assembly 210 includes a fixed bracket 2110, a push-pull actuator 2120, and a push rod 2130. The fixed bracket 2110 is locked to the support base 100, the push-pull actuator 2120 is fixedly disposed at the top of the fixed bracket 2110, the first end of the push rod 2130 is connected to the power output end of the push-pull actuator 2120, and the second end of the push rod 2130 faces the wing clamping position 110. It can be understood that since the push-pull actuator 2120 is fixedly disposed at the top of the fixed bracket 2110 locked to the support base 100, and the first end of the push rod 2130 is connected to the power output end of the push-pull actuator 2120, the push rod 2130 can be driven to extend and retract via the push-pull actuator 2120. Furthermore, since the second end of the push rod 2130 faces the wing clamping position 110, when the push rod 2130 extends or retracts, it can press the corresponding part of the skin structure against the corresponding position on the wing frame through the second end of the push rod 2130. Specifically, the push-pull actuator 2120 is a cylinder, and the first end of the push rod 2130 is fixedly connected to the piston rod of the cylinder. Specifically, the locking fixation can be achieved by tightening with screws or bolts, etc. Please refer to [link to relevant documentation]. Figure 1 and Figure 3 Furthermore, a claw 2141 is also installed on the fixed bracket 2110. The claw 2141 is used to engage with the fixture component 20 that is locked onto the wing frame to limit the position of the wing frame. The fixture component 20 is detachable after use.

[0041] Please see Figure 4In some embodiments, the push-pull actuator 2120 includes a mounting body 2121 and an air pipe 2122. The mounting body 2121 has a telescopic groove 2102, and the first end of the push rod 2130 is slidably disposed within the telescopic groove 2102. The air pipe 2122 is mounted on the mounting body 2121 and communicates with the telescopic groove 2102. The air pipe 2122 is used to introduce or extract gas into the telescopic groove 2102, so that the push rod 2130 extends and retracts within the telescopic groove 2102. It can be understood that when gas is introduced into the telescopic groove 2102 through the air pipe 2122, a high-pressure state is formed within the telescopic groove 2102, and the gas can push a portion of the push rod 2130 to extend out of the telescopic groove 2102. Conversely, when gas is extracted from the telescopic groove 2102 through the air pipe 2122, a negative pressure state is formed within the telescopic groove 2102, pushing a portion of the push rod 2130 to retract back into the telescopic groove 2102.

[0042] Please see Figure 4 Specifically, a receiving space is formed between a portion of the outer peripheral wall of the push rod 2130 and the inner wall of the telescopic slide 2102; a portion of the peripheral wall of the push rod 2130 protrudes into the receiving space, forming a retaining boss 2131; the retaining boss 2131 is slidably disposed within the receiving space and is used to retain a portion of the inner wall of the telescopic slide 2102. It can be understood that the retaining boss 2131 can move synchronously with the push rod 2130 within the receiving space, and can retain a portion of the inner wall of the telescopic slide 2102 to prevent the push rod 2130 from dislodging from the telescopic slide 2102. In this example, the accommodating space is provided with an elastic reset member 2123. The elastic reset member 2123 abuts against the inner wall of the locking boss 2131 and the telescopic slide 2102 respectively. When the push rod 2130 moves, it can act on the locking boss 2131 through the elastic reset member 2123 so that the push rod 2130 can be quickly reset.

[0043] Please see Figure 5 In some embodiments, the wing-side pushing assembly 210 further includes a guide assembly 2140; the guide assembly 2140 is located on the moving path of the pushing rod 2130 and is fixedly connected to the support base 100; the guide assembly 2140 has a guide sliding hole 2101, and the second end of the pushing rod 2130 is slidably disposed through the guide sliding hole 2101. It can be understood that because the guide assembly 2140 is located on the moving path of the pushing rod 2130, and the second end of the pushing rod 2130 is slidably disposed through the guide sliding hole 2101, the second end of the pushing rod 2130 can be stably supported against the skin structure under the guidance of the guide sliding hole 2101.

[0044] Please see Figure 5In some embodiments, the end face of the second end of the push rod 2130 is arc-shaped. It can be understood that the push rod 2130 is a rubber push rod 2130, and the arc-shaped end face of the second end of the push rod 2130 prevents wear on the skin structure when in contact with it. Simultaneously, the rubber push rod 2130 can deform during its contact with the skin structure, thereby generating friction between it and the skin structure.

[0045] Please see Figure 2 In some embodiments, the positioning detection mechanism 300 includes two camera detection components 310, each fixedly mounted on the support base 100. One camera detection component 310 is respectively disposed on each of the opposite sides of the wing clamping position 110, and the lens of the camera detection component 310 is directed towards the wing frame. It can be understood that the lens of the camera detection component 310 can acquire local image information of the wing frame after the skin structure is applied, thereby determining whether the skin structure is in position. It should be specifically noted that the method by which the camera detection component 310 acquires local image information of the wing frame after the skin structure is applied, and the method by which the positioning detection mechanism 300 monitors in real time whether the skin structure is displaced during riveting, are both prior art and not within the scope of this disclosure; therefore, they will not be elaborated upon here.

[0046] Please see Figure 2 In some embodiments, there are multiple positioning detection mechanisms 300, which are arranged sequentially along the length of the wing frame. It can be understood that because the multiple positioning detection mechanisms 300 are arranged sequentially along the length of the wing frame, multiple local image information of the wing frame after the skin structure is applied can be acquired simultaneously through the positioning detection mechanisms 300, thereby more accurately determining the overall position of the skin structure and more accurately detecting the overall displacement of the skin structure.

[0047] Please see Figure 2 and Figure 3 In some embodiments, the positioning detection mechanism 300 further includes a lifting support 320, which is disposed on the wing clamping position 110. The lifting support 320 has a telescopic rod for supporting and lifting the wing frame. It is understood that since the lifting support 320 is disposed on the wing clamping position 110, the base of the lifting support 320 is fixedly connected to the support base 100, and the telescopic rod of the lifting support 320 is telescopically disposed in the hydraulic groove of the base of the lifting support 320, the vertical height of the wing frame can be slightly adjusted by the support of the telescopic rod of the lifting support 320, so that the camera detection component 310 can acquire image information of the wing frame, including but not limited to photographs. Specifically, the lifting support 320 may be a lifting cylinder structure.

[0048] Please see Figures 1 to 5 This disclosure also provides a wing 10 positioning and processing apparatus, including a wing skin positioning fixture of any of the above embodiments. It is understood that by applying the wing skin positioning fixture of this disclosure to the wing 10 positioning and processing apparatus, since the positioning detection mechanism 300 is mounted on the support base 100, when the skin structure is draped over the outer surface of the wing frame placed on the support base 100, the positioning detection mechanism 300 can obtain the position of the skin structure to determine whether the skin structure is in position. Then, at least one wing positioning mechanism 200 can press the first part of the skin structure to the wingtip position of the wing frame, and at least another wing positioning mechanism 200 can press the skin structure further. At the wing mid-section of the wing frame, and further at the tail section of the wing frame, the third part of the skin structure is pressed by at least one other wing positioning mechanism 200. Thus, the corresponding parts of the skin structure can be fixed to the corresponding positions of the wing frame by at least three wing positioning mechanisms 200, thereby ensuring that the skin structure remains in close contact with the wing frame during the riveting process. Moreover, the positioning detection mechanism 300 can monitor in real time whether the skin structure is displaced during riveting, thereby reducing the cumulative displacement between the skin structure and the wing frame and improving the overall quality of the wing 10.

[0049] Compared with the prior art, this disclosure has at least the following advantages:

[0050] The aforementioned positioning fixture for wing skin, with the positioning detection mechanism 300 mounted on the support base 100, can determine the position of the skin structure when it is draped over the outer surface of the wing frame placed on the support base 100, by obtaining the position of the skin structure. Then, at least one wing positioning mechanism 200 presses the first part of the skin structure onto the wing tip of the wing frame, and at least another wing positioning mechanism 200 presses the skin structure onto the wing mid-wing position. Furthermore, at least another wing positioning mechanism 200 presses the third part of the skin structure onto the wing tail position. Thus, at least three wing positioning mechanisms 200 respectively fix the corresponding parts of the skin structure to the corresponding positions on the wing frame, ensuring the skin structure remains in close contact with the wing frame during riveting. The positioning detection mechanism 300 can also monitor in real time whether the skin structure shifts during riveting, thereby reducing the cumulative displacement between the skin structure and the wing frame and improving the overall quality of the wing 10.

[0051] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
