Description
Technical Field
[0001] This invention relates to the field of honeycomb component manufacturing technology, and more specifically, to a method for processing thin-walled honeycomb components. Background Technology
[0002] With the development of modern aviation technology, higher requirements have been placed on the stealth performance of aircraft, leading to the introduction of a large number of new high-performance materials. Honeycomb absorbing materials, with their high strength-to-weight ratio and many other advantages, are widely used in next-generation combat aircraft. Due to the inherent characteristics of honeycomb structures, they are often bonded together with other composite materials to form honeycomb-composite structures. Therefore, the assembly relationship between other materials and the honeycomb must be considered when designing honeycomb structures. Consequently, some honeycomb sidewalls may have no more than one cell, and the sidewall depth may exceed the cell width. However, honeycomb sidewalls are prone to loss, deformation, and damage under current processing techniques, leading to product scrap. Summary of the Invention
[0003] The present invention aims to provide a method for thin-wall processing of honeycomb components, which is applied to the thin-wall processing of honeycomb components and can avoid the problems of missing, deformed or damaged thin walls of honeycomb components during processing, thereby reducing the scrap rate of honeycomb components, thereby improving product quality and processing efficiency, increasing yield, and ultimately reducing processing costs.

[0005] In an optional implementation, the side of the positioning area opposite the thin wall is the positioning sidewall. Before processing the outer side of the honeycomb part, the thickness of the honeycomb part corresponding to the thin wall side is ≥δ1; after processing the outer side of the honeycomb part, the thickness of the thin wall is δ2. Among them, δ1 is greater than δ2, and δ1 is greater than the length of one cell of the honeycomb component.
[0006] In an optional implementation, the step of machining the positioning area within the honeycomb element includes: The area to be processed within the honeycomb component is determined based on the positioning area. The area to be processed is roughed by using a tool from the inside out. When the tool moves toward the positioning sidewall, a first processing allowance is left.

[0007] In an optional implementation, the first machining allowance is 0.5mm-2mm; When roughing the area to be machined, the tool linear speed is 150m / s-300m / s and the step distance is 0.5mm-2mm. When finishing milling the inner peripheral wall of the area after rough machining, the tool linear speed is 150m / s-300m / s and the feed per tooth is 0.01-0.03. After finishing milling the inner peripheral wall, the bottom surface is finished milled using the same parameters to form the positioning area.
[0008] In an optional embodiment, the step of processing at least one side of the outer side of the honeycomb member corresponding to the thin wall includes: Use a cutting tool to rough machine the outer side of the honeycomb part corresponding to the thin wall, and leave a second machining allowance during machining; The outer side of the rough-machined honeycomb component is then precision milled using a milling cutter along the tool axis.
[0009] In an optional embodiment, the second machining allowance is 1mm-2mm, and during the roughing process, the tool linear speed is 150m / s-300m / s, and the feed per tooth is 0.01-0.03. When precision milling the outer side of the honeycomb component, the machining speed is 150m / s-300m / s and the step distance is 0.5mm-2mm.
[0010] In an optional embodiment, when the positioning fixture is assembled to the positioning area, the positioning fixture is made to fit against multiple sides of the positioning area, and the inner side of the positioning area that fits against the positioning fixture includes a positioning sidewall.
[0011] In an optional embodiment, the side of the positioning fixture that is in contact with the positioning sidewall is the positioning sidewall. An adhesive layer is disposed on the positioning sidewall, and when the positioning fixture is assembled into the positioning area, the adhesive layer on the positioning sidewall is bonded to the positioning sidewall.
[0012] In an optional implementation, the positioning fixture with an adhesive layer is interference-fitted with the positioning area.
[0013] In an optional implementation, after the positioning fixture is assembled into the positioning area, the maximum gap between the positioning side and the positioning sidewall is 0.05mm-0.1mm smaller than the thickness of the adhesive layer.
[0014] The beneficial effects of the thin-walled honeycomb component processing method provided in this embodiment of the invention include: This method for processing thin-walled honeycomb components includes: determining the location of the thin-walled portion to be processed in the honeycomb component, and the shape of the positioning area within the honeycomb component; processing the positioning area within the honeycomb component; fabricating a positioning fixture based on the positioning area, and assembling the positioning fixture to the positioning area; processing at least one side of the outer surface of the honeycomb component corresponding to the thin-walled portion; removing the positioning fixture, and inspecting the dimensions of the honeycomb component. This method for processing thin-walled honeycomb components can avoid problems such as missing, deformed, or damaged thin walls during processing, thereby reducing the scrap rate of honeycomb components. This improves product quality and processing efficiency while increasing the yield rate, ultimately reducing processing costs. Attached Figure Description

[0024] Please refer to Figures 1-9 ,in Figure 1 The steps of the processing method for the thin-walled 101 of the honeycomb component 100 are shown. Figure 2 The structure of the honeycomb component 100 is shown. Figure 2 and Figure 3 The assembly method of the honeycomb component 100 and the positioning fixture 200 is shown. Figures 4-9 The detailed steps of the processing method for the thin-walled 101 of the honeycomb component 100 are shown; it should be noted that, in Figures 5-9 In order to facilitate the illustration of the outline of the tool 300 and the positioning area 110, the outline shape of the honeycomb part 100 is set as a cuboid for easy illustration. This embodiment provides a method for processing a thin-walled honeycomb component 100 101, including: Determine the position of the thin wall 101 to be processed in the honeycomb part 100, and the shape of the positioning area 110 in the honeycomb part 100; The positioning area 110 is machined within the honeycomb component 100; Make a positioning fixture 200 according to the positioning area 110, and assemble the positioning fixture 200 into the positioning area 110; At least one side of the outer side of the honeycomb component 100 corresponding to the thin wall 101 is processed; Remove the positioning fixture 200 and check the dimensions of the honeycomb component 100.
[0025] The working principle of the honeycomb component 100 thin-walled 101 processing method is as follows: In the process of processing the honeycomb part 100 using the honeycomb part 100 thin wall 101 processing method, the position of the thin wall 101 to be processed in the honeycomb part 100 is determined according to the structural shape of the honeycomb part 100 and the processing requirements. Moreover, depending on the structural shape of the honeycomb part 100, the thin wall 101 can be a plane or an arc surface. In this embodiment, the thin wall 101 is a plane as an example for explanation. It should be noted that the thin wall 101 being a plane or an arc surface means that the side surface of the thin wall 101 is in the same plane or has a certain curvature. Once the thin wall 101 to be processed on the honeycomb part 100 is determined, the side positions on the honeycomb part 100 that need to be processed can be determined based on the position of the thin wall 101. On this basis, in order to improve the success rate of processing the thin wall 101 feature and avoid problems such as missing, deformed or damaged features during processing, the shape and position of the positioning area 110 within the honeycomb part 100 are determined based on the position of the thin wall 101 and the structural shape of the honeycomb part 100. Thus, the positioning area 110 for installing the positioning fixture 200 can be processed within the honeycomb part 100. During the processing of the thin wall 101, the positioning fixture 200 plays a role in auxiliary positioning and structural support for the honeycomb part 100. This can effectively avoid problems such as missing, deformed or damaged features of the thin wall 101 due to high positioning difficulty and changes in structural strength during processing. Furthermore, after the positioning area 110 for mounting the positioning fixture 200 is machined on the honeycomb part 100, the side of the outer side of the honeycomb part 100 corresponding to the thin wall 101 can be machined according to the relative position of the thin wall 101 feature of the target on the honeycomb part 100. Therefore, based on the processing of the above-mentioned positioning area 110, the internal processing of the honeycomb part 100 can be realized. On this basis, after installing the positioning fixture 200, the honeycomb part 100 with the thin wall 101 can be obtained by processing the outer side of the honeycomb part 100. Moreover, during this process, the forming process of the positioning area 110 can not only meet the requirements of the installation positioning fixture 200, but also simultaneously complete the processing of the inner side of the thin-walled 101 feature, so as to cooperate with the processing on the outer side of the honeycomb part 100, thereby completing the processing of the thin-walled 101 feature of the honeycomb part 100. In summary, the method for processing the thin-walled 101 of the honeycomb component 100 is applied to the processing of the thin-walled 101 of the honeycomb component 100. During the processing, the positioning area 110 is processed to process the inner side of the thin-walled 101 feature. The positioning fixture 200 is also installed, which provides auxiliary positioning and structural support. This avoids the problem of missing, deformed or damaged thin-walled 101 of the honeycomb component 100 during processing, thereby reducing the scrap rate of the honeycomb component 100. This improves product quality and processing efficiency, increases the yield rate, and ultimately reduces processing costs.
[0026] Further, please refer to Figures 1-9 In this embodiment, the positioning area 110 is positioned on the side opposite the thin wall 101 as a positioning sidewall 102. Before processing the outer side of the honeycomb part 100, the thickness of the honeycomb part 100 on the side corresponding to the thin wall 101 is ≥ δ1. After processing the outer side of the honeycomb part 100, the thickness of the thin wall 101 is δ2. Wherein, δ1 is greater than δ2, and δ1 is greater than the length of one honeycomb cell of the honeycomb part 100.
[0027] That is, taking the thickness of the thin wall 101 on the honeycomb part 100 as δ1 after the positioning area 110 is processed and before the outer side of the honeycomb part 100 is processed as an example, the processing steps before this are all processing of the positioning area 110, and do not involve processing of the outer side of the honeycomb part 100. Therefore, by making δ1 greater than the length of a honeycomb cell of the honeycomb part 100, and by making δ2 less than the length of a honeycomb cell of the honeycomb part 100, sufficient processing allowance can be left on the basis of completing the processing of the inner side of the thin wall 101 of the honeycomb part 100. The purpose is that during the processing of the positioning area 110, the processing allowance left can ensure the structural strength of the honeycomb part 100, and avoid the reduction of its own structural strength during the processing of the positioning area 110, which would lead to structural deformation or damage to the honeycomb part 100. Moreover, after the outer side of the honeycomb part 100, the thickness of its thin wall 101 is δ2, which is less than the thickness before processing, that is, δ1 is greater than δ2.
[0028] Further, please refer to Figures 1-9 In this embodiment, as can be seen from the above, the purpose of processing the positioning area 110 is to form the position of the assembly positioning fixture 200 within the honeycomb component 100 and to complete the processing of the inner side of the thin wall 101. Therefore, when processing the positioning area 110, it is necessary not only to ensure that the structural shape of the positioning area 110 can be adapted to the positioning fixture 200, but also to meet the shape and position requirements of the target thin wall 101. Therefore, the step of processing the positioning area 110 within the honeycomb component 100 includes: The area to be processed within the honeycomb component 100 is determined according to the positioning area 110. The area to be processed is rough processed by the tool 300 from the inside to the outside. When the tool 300 moves toward the positioning sidewall 102, a first processing allowance is left. The inner peripheral wall of the area after rough machining is finished by milling with a milling cutter along the 300 axis of the tool to form the positioning area 110.
[0029] Through the above processing steps, the area to be processed can be planned on the honeycomb part 100 according to the position of the thin wall 101 and the structural shape of the preset positioning fixture 200. Then, the tool 300 can be used to perform rough processing on the area to be processed from the inside out. After the rough processing is completed, the inner peripheral wall of the rough processed area is precision milled. Moreover, in order to improve the processing accuracy during the rough processing, the purpose is to simultaneously complete the processing of the inner side of the thin wall 101 when processing the positioning area 110. Therefore, a first processing allowance needs to be left during the rough processing to facilitate the precision milling.
[0030] Furthermore, during the roughing process, the first machining allowance is 0.5mm-2mm; and when roughing the area to be machined, the linear speed of the tool 300 is 150m / s-300m / s, and the step distance is 0.5mm-2mm; while when finishing milling the inner peripheral wall of the area after roughing, the linear speed of the tool 300 is 150m / s-300m / s, and the feed per tooth is 0.01-0.03; after finishing milling the inner peripheral wall, the bottom surface is finished milled using the same parameters to form the positioning area 110.
[0031] Furthermore, by means of roughing and finishing milling, the positioning area 110 can be formed on the honeycomb, and the structure and shape of the positioning area 110 are adapted to the positioning fixture 200, and the machining of its positioning sidewall 102 meets the machining requirements of the inner side of the thin wall 101.
[0032] When processing the outer side of the honeycomb member 100, this embodiment processes the side of the honeycomb member 100 corresponding to the thin wall 101. However, in other embodiments of the present invention, other sides of the honeycomb member 100 may also be processed. The step of processing at least the side of the outer side of the honeycomb member 100 corresponding to the thin wall 101 includes: The outer side of the honeycomb part 100 corresponding to the thin wall 101 is rough machined using tool 300, and a second machining allowance is left during machining. The outer side of the rough-machined honeycomb part 100 is precision milled by using a milling cutter to mill along the axial direction of the tool 300.
[0033] Therefore, as can be seen from the above processing method, in order to improve the quality and accuracy of processing, the outer side of the honeycomb part 100 is roughed and finished milled, and a second machining allowance is left for finish milling during the roughing process.
[0034] Specifically, the second machining allowance is 1mm-2mm, and during roughing, the linear speed of the tool 300 is 150m / s-300m / s, and the feed per tooth is 0.01-0.03; when finishing milling the outer side of the honeycomb part 100, the machining linear speed is 150m / s-300m / s, and the step distance is 0.5mm-2mm.
[0035] Further, please refer to Figures 1-9 In this embodiment, as described above, when the positioning fixture 200 is assembled to the positioning area 110, its structural function is to position the honeycomb component 100 in the processing state and to support the honeycomb component 100, thereby improving its structural strength. Therefore, to enhance the supporting effect of the positioning fixture 200 on the honeycomb component 100 when assembling the positioning fixture 200 to the positioning area 110, the positioning fixture 200 is fitted to multiple sides of the positioning area 110, and the inner side of the positioning area 110 fitted to the positioning fixture 200 includes a positioning sidewall 102. In other embodiments of the present invention, since the processed thin wall 101 is located on one side of the honeycomb component 100, the positioning fixture 200 can also be held against the positioning sidewall 102, that is, it can only contact the inner side of the thin wall 101 of the positioning area 110.
[0036] Furthermore, to improve processing stability and prevent displacement of the relative position of the positioning fixture 200 after it is installed in the positioning area 110, the side of the positioning fixture 200 that is used to fit against the positioning sidewall 102 is designated as the positioning side surface 201. An adhesive layer is provided on the positioning side surface 201, and when the positioning fixture 200 is assembled into the positioning area 110, the adhesive layer on the positioning side surface 201 is bonded to the positioning sidewall 102. That is, after the positioning fixture 200 is assembled into the positioning area 110, an adhesive layer can be provided on its positioning side surface 201, so that while the positioning fixture 200 cooperates with the positioning area 110, the adhesive layer ensures that the positioning fixture 200 is installed within the positioning area 110. It should be noted that in this embodiment, the adhesive layer is double-sided tape, while in other embodiments, other types of adhesive materials can be selected, and the adhesive layer can also be used on other sides of the positioning area; and when the positioning fixture 200 is removed from the positioning area 110, the part needs to be soaked in alcohol before removal.
[0037] Furthermore, to improve the stability of the connection, the positioning fixture 200 with the adhesive layer is configured to have an interference fit with the positioning area 110. This arrangement aims to improve the strength of the bond. To ensure the interference fit between the positioning fixture 200 and the positioning area 110, after the positioning fixture 200 is assembled into the positioning area 110, the maximum gap between the positioning side 201 and the positioning sidewall 102 is 0.05mm-0.1mm smaller than the thickness of the adhesive layer. It should be noted that with this arrangement, after the side of the positioning fixture 200 opposite to the positioning side 201 is fitted into the positioning area 110, the distance between the positioning side 201 and the positioning sidewall 102 is the maximum gap. Based on this, the width reserved to accommodate the adhesive layer is maximized. Since the maximum gap is less than the thickness of the adhesive layer, the assembly of the positioning fixture 200 into the positioning area 110 can achieve an interference fit.
[0038] Based on the above, please refer to Figures 1-9 The implementation steps of the processing method for the thin-walled honeycomb component 100 101 include: Determine the position of the thin wall 101 to be processed in the honeycomb part 100, and the shape of the positioning area 110 in the honeycomb part 100; Machining the positioning area 110 within the honeycomb component 100 includes: determining the area to be machined within the honeycomb component 100 based on the positioning area 110; roughing the area to be machined using a tool 300 from the inside out, with a linear speed of 150m / s-300m / s and a step distance of 0.5mm-2mm; leaving a first machining allowance of 0.5mm-2mm when the tool 300 moves towards the positioning sidewall 102; finishing milling the inner peripheral wall of the rough-machined area using a milling cutter along the axial direction of the tool 300, with a linear speed of 150m / s-300m / s and a feed per tooth of 0.01-0.03; and finishing milling the inner peripheral wall using the same parameters to finish mill the bottom surface, forming the positioning area 110. A positioning fixture 200 is fabricated based on the positioning area 110 and assembled onto the positioning area 110. The positioning fixture 200 is then fitted to multiple sides of the positioning area 110, with the inner side of the positioning area 110 fitted to the positioning fixture 200 including a positioning sidewall 102. The side of the positioning fixture 200 that fits against the positioning sidewall 102 is a positioning side 201. An adhesive layer is disposed on the positioning side 201, and when the positioning fixture 200 is assembled onto the positioning area 110, the adhesive layer of the positioning side 201 is bonded to the positioning sidewall 102. Furthermore, the positioning fixture 200 with the adhesive layer is interference-fitted with the positioning area 110. This arrangement aims to improve the bonding strength; the maximum gap between the positioning side 201 and the positioning sidewall 102 is 0.05mm-0.1mm smaller than the thickness of the adhesive layer. At least the outer side of the honeycomb component 100 corresponding to the thin wall 101 is machined, including: roughing the outer side of the honeycomb component 100 corresponding to the thin wall 101 using a tool 300, and leaving a second machining allowance during machining; the second machining allowance is 1mm-2mm, and during the roughing process, the linear speed of the tool 300 is 150m / s-300m / s, and the feed per tooth is 0.01-0.03; finish milling the outer side of the honeycomb component 100 after roughing, using a milling cutter to mill along the axial direction of the tool 300; when finish milling the outer side of the honeycomb component 100, the linear speed during machining is 150m / s-300m / s, and the step distance is 0.5mm-2mm; Remove the positioning fixture 200 and check the dimensions of the honeycomb part 100; after processing, use specific gauge blocks to check whether the embedded dimensions are qualified, and remove the part after it is qualified; The positioning area 110 is positioned on the side opposite the thin wall 101 as a positioning sidewall 102. Before processing the outer side of the honeycomb part 100, the thickness of the honeycomb part 100 on the side corresponding to the thin wall 101 is ≥ δ1. After processing the outer side of the honeycomb part 100, the thickness of the thin wall 101 is δ2. δ1 is greater than δ2, and δ1 is greater than the length of one honeycomb cell of the honeycomb part 100.
[0039] The processing method for the thin-walled 101 honeycomb component has the following advantages: This method for processing thin-walled sections 101 of the honeycomb component 100 is applied to the processing of thin-walled sections 101 of the honeycomb component 100. It can solve the processing difficulties of sidewalls smaller than single-cell sections, reduce the scrap rate, and, through the processing positioning area 110, can process the inner side of the thin-walled section 101 feature. It can also install the positioning fixture 200, which requires less installation time. The positioning fixture 200 can play a role in auxiliary positioning and structural support, thereby avoiding the problems of missing, deformed or damaged thin-walled sections 101 of the honeycomb component 100 during processing, and reducing the scrap rate of the honeycomb component 100. This can improve product quality and processing efficiency, increase yield, and reduce processing costs.
[0040] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
