[0002] Among the many parts of flight equipment, there are large-sized parts that need to be manufactured in one piece during the processing and manufacturing process, which causes great trouble to the technicians. For example, in the process of processing the skin of flight equipment, the use of aluminum skin with light weight has weak physical properties and occupies a large area, which causes great trouble to on-site processing.

[0003] In order to solve the above technical problems, technicians designed corresponding tooling for each specification of aluminum skin and provided a larger processing site to meet the processing requirements. However, in the actual application process, the technicians found that the existing technology has at least the following technical problems:

[0004] On the one hand, the size of the aluminum skin of flight equipment is much larger than the processing size of conventional parts, and the maximum length can reach more than ten meters. Therefore, if corresponding processing tools are designed for each specification of aluminum skin, it will cause great pressure on the processing site and warehouse occupation.

[0005] Secondly, in the process of fixing the flight equipment skin, although the technicians considered using adsorption to fix it, the designed tooling had fixed specifications and the adsorption holes were also fixed, which could not flexibly meet the skin manufacturing process of various sizes.

[0027] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0028] The term "plurality" in the embodiments of the present invention refers to two or more than two. In view of this, in the embodiments of the present invention, "plurality" can also be understood as "at least two". In addition, it should be understood that in the description of the embodiments of the present invention, the words "first", "second" and the like are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0029] See also Figure 1-Figure 3 In order to solve the technical problems existing in the prior art, an embodiment of the present invention provides a processing tool for aluminum skin of flight equipment, the processing tool comprising: a bottom support structure 10, the support strength of the bottom support structure 10 is configured according to the processing strength of the aluminum skin; a processing platform 20 is fixedly arranged on the top of the bottom support structure 10, the projection of the processing platform 20 completely covers the bottom support structure 10, a plurality of adsorption holes 21 are evenly arranged on the processing platform 20, each adsorption hole 21 is connected to a vacuum pump 40 through an air path (not shown), and the processing platform 20 is evenly divided into a plurality of sub-levels. A processing platform 22, each sub-platform 22 is evenly provided with at least one adsorption hole 21; a plurality of supporting and fixing devices 30 are arranged one by one at the bottom of each sub-platform 22, and the supporting and fixing devices 30 include a T-shaped piece 31, and the T-shaped piece 31 is matched with a T-shaped slot (not shown) on a machine tool; a plurality of grooves 23 are evenly arranged on the top surface of the processing platform 20, and the grooves 23 are matched with a sealing component (not shown), and the sealing component is embedded in the grooves 23 around the periphery of the aluminum skin, and the sealing component is located within the projection range of the aluminum skin, and the height of the sealing component is greater than the depth of the groove.

[0030] In a possible implementation, first, a bottom support structure 10 that can support the processing of the entire aluminum skin is manufactured. The technicians can determine the specific parameter structure of the bottom support structure 10 according to the actual warehouse space requirements and the main requirements of the processing size. For example, in this embodiment, according to the big data analysis of the aluminum skin size data processed and manufactured by the factory, the length and width of the bottom support structure 10 can be configured to 1*2m, which can meet most processing requirements. At the same time, according to the height space available after the processing tool is placed on the machine tool, the height of the bottom support structure 10 is configured. On this basis, the processing strength of the aluminum skin is further obtained to determine the maximum force applied by the machine tool to the processing tool, and the mechanical structure design of the bottom support structure 10 is determined according to the maximum force. Then, a processing platform 20 is fixed on the top of it to complete the main configuration of the processing tool.

[0031] In the actual aluminum skin processing scenario, there are various processing sizes. If corresponding processing tools are customized for each processing size, on the one hand, the space occupied by the warehouse will be greatly increased, resulting in space waste; on the other hand, the size of the processing tools customized for large-size aluminum skins is also relatively large, which puts great pressure on warehouse storage, and even cannot be stored in the warehouse, causing great trouble to management personnel; thirdly, customized chemical tools also cause additional operating costs for enterprises and cannot meet the actual needs of enterprises.

[0032] In order to solve the above technical problems, the bottom support structure 10 is designed to occupy an area smaller than the processing platform 20, that is, the projection of the processing platform 20 completely covers the bottom support structure 10. When a single processing tool cannot meet the processing needs of larger aluminum skins, multiple processing tools can be directly seamlessly spliced ​​to meet the processing needs of larger sizes. Such a design can effectively reduce the volume occupied by a single processing tool and greatly reduce its space occupancy. At the same time, technicians can configure processing tools of various sizes according to actual needs to take into account space occupancy and processing requirements, thereby reducing the space requirements of the processing scene during the processing process.

[0033] For example, in the second embodiment, an aluminum skin with a length of 10m and a width of 2m needs to be processed, and a single processing tool cannot meet the requirement of this size. Therefore, the number of processing tools required is determined according to the size, and the corresponding number of processing tools are seamlessly spliced. Then, all the processing tools are fixed on the machine tool through the corresponding supporting and fixing device 30 to meet the personalized processing needs of different sizes.

[0034] In an embodiment of the present invention, in order to further meet the processing requirements of small-sized aluminum skins, reduce the requirements for adsorption capacity during the processing process, and reduce the complexity of adsorption control of the aluminum skin during the processing process, the processing platform 20 can be further evenly divided into multiple sub-platforms 22. For example, in an embodiment of the present invention, the processing platform 20 is divided into four sub-platforms 22: upper left, lower left, upper right, and lower right. When only a smaller area of ​​aluminum skin needs to be processed, it only needs to be laid on a sub-platform 22 and adsorbed without using the entire processing platform 20.

[0035] After configuring the bottom support structure 10 and the processing platform 20, the processing tooling needs to be fixed on the machine tool. In traditional factories, the processing tooling is often fixed on the machine tool by bolts. However, in the field of aluminum skins for flight equipment, the processing tooling is relatively large. On the one hand, when the processing tooling is placed on the machine tool, there is little or no remaining space around it, so it cannot be bolted from all sides. On the other hand, due to the limitation of the machine tool processing space, the bottom space of the bottom support structure 10 is also very small, and technicians cannot crawl to the bottom of the bottom support structure 10 to perform fixing operations, which causes great trouble to the technicians.

[0036] In order to solve the above technical problems, a plurality of supporting and fixing devices 30 are designed at the bottom of the bottom supporting structure 10, and each bottom supporting and fixing device 30 is arranged one by one at the bottom of the sub-platform 22. Through the supporting and fixing device 30, it can cooperate with the T-slot on the machine tool to stably fix the processing tooling on the machine tool.

[0037] See also Figure 4 In an embodiment of the present invention, the supporting and fixing device 30 includes a fixed sliding rod 32, an automatic telescopic device 33 and the T-shaped piece 31. The fixed sliding rod 32 is fixedly arranged at the bottom of the corresponding sub-platform 22 and is arranged along the diagonal of the corresponding sub-platform 22. The automatic telescopic device 33 is sleeved on the fixed sliding rod 32; the automatic telescopic device 33 includes a horizontal rotating device (not shown) arranged at the bottom, and the automatic telescopic device 33 controls the horizontal rotating device to move in the vertical direction; the T-shaped piece 31 is detachably connected to the horizontal rotating device, and the horizontal rotating device controls the T-shaped piece 31 to rotate in the horizontal direction.

[0038] In one possible implementation, a fixed slide bar 32 is provided at the bottom of each sub-platform 22. The fixed slide bar 32 is provided along the diagonal of the sub-platform 22. On the one hand, it can effectively improve the structural strength of the sub-platform 22, ensure that the sub-platform 22 can maintain sufficient flatness during the processing, and improve the processing flatness of the aluminum skin; on the other hand, it can ensure that the stroke of the automatic telescopic device 33 can fully cover the sub-platform 22, and meet the support requirements of aluminum skins of various sizes during the processing. The automatic telescopic device 33 is sleeved on the fixed slide bar 32. After the processing tool is installed on the machine tool, the technician determines the support center point of the supporting fixture 30 according to the laying position of the aluminum skin on the processing platform 20, and then searches for the T-slot located on the stroke of the fixed slide bar 32 and closest to the support center point. Then, the automatic telescopic device 33 is manually moved along the fixed slide bar 32 to the T-slot, and then the T-shaped piece 31 at the bottom of the automatic telescopic device 33 is controlled to rotate to be parallel to the T-slot on the machine tool, and then the T-shaped piece 31 is controlled to telescope downward to embed into the T-slot. For example, the automatic telescopic device 33 includes a cylinder (not shown), and then the T-shaped piece 31 at the bottom of the automatic telescopic device 33 is controlled to rotate, such as a horizontal rotating motor (not shown) is configured at the bottom of the automatic telescopic device 33 to engage the T-shaped piece 31 and realize the fixation of the processing tool on the machine tool.

[0039] After the processing is completed, the operation of each component on the reverse control support and fixing device 30 can be removed from the machine tool. No further details will be given here, thereby effectively ensuring the stability and fixing strength of a single or multiple processing tools on the machine tool, and ensuring the processing reliability of the aluminum skin.

[0040] As can be seen from the accompanying drawings, when in use, the bottom of the T-shaped piece 31 protrudes from the bottom of the bottom supporting structure 10. Therefore, after the processing tooling is removed from the machine tool, the T-shaped piece 31 needs to be immediately removed from the horizontal rotating device and properly preserved so that the processing tooling can be placed flat in the warehouse for storage to avoid damage to the supporting and fixing device 30.

[0041] In an embodiment of the present invention, through a detailed analysis of the actual problems faced by the aluminum skin of flight equipment in the processing and manufacturing process, the existing processing tooling is improved and designed for each pain point, and the vacuum adsorption + bottom automatic fixation method is adopted to effectively reduce the space occupied when installing and fixing the processing tooling. It is no longer necessary for technicians to crawl to the bottom of the processing tooling to perform fixing operations, which greatly reduces the difficulty of operation. At the same time, it effectively ensures the processing stability and flatness of the aluminum skin on the processing platform 20, meeting the high-precision processing requirements.

[0042] In actual application, the position of the automatic telescopic device 33 on the fixed slide bar 32 needs to be manually adjusted, either by adjusting it to the set position in advance before installing the processing tooling, or by having a technician crawl to the bottom to manually adjust it after installation. However, in the application process, the automatic telescopic device 33 that is adjusted in advance may not fit the T-shaped piece 31 into the T-shaped groove due to a slight position deviation, and the technician still needs to crawl to the bottom of the processing tooling to manually adjust it, and the bottom space is very narrow, which causes great trouble to the technician.

[0043] In order to solve the above technical problem, in an embodiment of the present invention, the supporting and fixing device 30 includes a horizontal driving device (not shown), and the horizontal driving device is used to drive the automatic telescopic device 33 to move along the extension direction of the fixed sliding rod 32.

[0044] In one possible implementation, the horizontal drive device is, for example, a linear motor. In a second embodiment, the fixed slide rod 32 and the horizontal drive device are a set of screw devices designed to match each other. The linear motor or the screw device can drive the entire supporting and fixing device 30 to move along the fixed slide rod 32, and technicians are no longer required to manually move the automatic telescopic device 33, thereby further reducing the difficulty of configuring the processing tooling and improving the user experience.

[0045] After the processing tooling is fixedly installed on the machine tool, the incoming parts of the aluminum skin are prepared for processing. A plurality of adsorption holes 21 are arranged on the processing platform 20, and each adsorption hole 21 is connected to the vacuum pump 40 through an air path. In the embodiment of the present invention, each sub-platform 22 is evenly configured with at least one adsorption hole 21, and a negative pressure is formed on the ground of the incoming material through the adsorption hole 21, so that the incoming material is adsorbed and fixed on the surface of the processing platform 20, thereby stably processing and forming the aluminum skin. At the same time, a plurality of grooves are evenly arranged on the top surface of the processing platform, and the arrangement density of the grooves can be set by the technicians according to actual needs. The grooves are matched with the sealing components (not shown). Preferably, a plurality of grooves 23 are connected horizontally and vertically to form a mesh groove, and the grooves 23 are not connected to the adsorption holes 21.

[0046] In an embodiment of the present invention, the sealing component is preferably a sealing strip, which is matched with the groove 23, and the height of the sealing strip is greater than the depth of the groove 23, that is, after the sealing strip is embedded in the groove 23, part of the sealing strip is still exposed on the surface of the processing platform, and the exposed sealing strip fits with the laid incoming material to form a sealing effect on the bottom of the incoming material.

[0047] In actual application, the technicians lay the sealing strips in the set area according to the set area for laying the aluminum skin in advance. Specifically, the sealing strips are laid in the groove 23 at the inner edge of the set area to form a closed circle. When the incoming material of the aluminum skin is laid on the set area, the incoming material fits tightly with the sealing strips to form a sealing ring at its bottom. At this time, the technicians can determine the adsorption holes 21 in the sealing ring and control the corresponding adsorption holes 21 to open, so as to adsorb the incoming material to the processing platform 20 for processing to form the aluminum skin.

[0048] However, in actual application, the above operation method requires manual determination of the adsorption holes 21 in the sealing ring and manual control of the corresponding adsorption holes, thus causing additional workload for technicians and reducing work efficiency.

[0049] In order to solve the above technical problems, in the first embodiment, an openable and closable valve (not shown) is provided at the opening of each adsorption hole 21 .

[0050] In the embodiment of the present invention, preferably, the openable and closable valve is a negative pressure valve.

[0051] In actual application, after laying the incoming material on the processing platform 20, the technicians can directly start the vacuum pump. For the adsorption holes 21 exposed to the outside, they will be automatically closed due to the action of the negative pressure valve, and no air leakage will occur; for the adsorption holes 21 sealed in the closed circle, they will be connected under the action of the vacuum pump, and the air at the bottom of the incoming material will be sucked away to form a negative pressure, which will firmly adsorb it on the processing platform 20, avoiding the movement or shaking of the incoming material during the processing, and effectively ensuring the processing stability and reliability of the aluminum skin.

[0052] However, in actual application, due to shaking and various forces during the processing, the bottom of the aluminum skin may leak due to shaking and other reasons. The existing technology is unable to detect the leakage phenomenon, thus there is a potential risk of loosening of the aluminum skin and cannot meet the actual processing requirements.

[0053] In order to solve the above technical problems, after the future material is laid on the processing platform 20, each adsorption hole 21 is automatically controlled to be turned on, and the air pressure of the adsorption hole 21 is detected, and the exposed adsorption holes 21 are automatically detected and closed, and then the remaining adsorption holes 21 are controlled to perform the aluminum skin adsorption operation. During the processing, the air pressure data in each of the remaining adsorption holes 21 is monitored in real time. Once it is detected that the air pressure in a certain adsorption hole 21 is less than the set value, it is determined that a leak has occurred, so the machine tool is controlled to stop processing immediately to avoid damage to the aluminum skin and ensure the yield of parts.

[0054] In actual application, since the surface of the incoming aluminum skin is not a mirror surface but slightly uneven, after it is laid on the processing platform 20, if only the adsorption holes 21 are used to adsorb the incoming material in the nearby area, other concave and convex parts of the incoming material may be isolated from the adsorption holes 21 and retain some air. In the subsequent processing, the air in the above-mentioned concave and convex parts may leak to other parts due to shaking, movement, etc., and further lead to a decrease in the overall adsorption performance of the incoming material, resulting in a potential risk of loosening.

[0055] In order to solve the above technical problems, each adsorption hole 21 is connected to at least one groove 23, and the mesh groove formed by the groove 23 can greatly increase the effective range of each adsorption hole 21, greatly improve the adsorption effect, and at the same time can effectively discharge the air covered by the concave and convex parts far away from the adsorption hole 21 through the adsorption hole 21, thereby ensuring the adsorption stability and adsorption reliability in the subsequent processing process, and improving the processing accuracy and reliability.

[0056] Furthermore, in the embodiment of the present invention, in order to meet the requirements of precise processing of the aluminum skin, an alignment structure may be provided on the processing platform 20. For example, the alignment structure is a scale. The technician may fix the incoming aluminum skin in a set area according to the alignment structure, and perform precise processing on the aluminum skin according to the alignment structure. Furthermore, since different parts may have different surface structures, for example, when processing parts with protruding structures on the surface, it is necessary to support the bottom thereof. Therefore, in the embodiment of the present invention, a detachable boss 24 may be provided on the processing platform 20. The detachable boss 24 is matched with the shape and setting position of the aluminum skin, and is used to lay the aluminum skin on the processing platform 20 according to a preset flatness.
