Description

[0029] See also Figure 1-3, an embodiment of the present invention provides a processing device for a high-precision front beam component on a flight device, the high-precision front beam component includes X groups of ear plate structures 100, each group of ear plate structures 100 includes Y pieces of ears to be drilled 110, Z processing holes 111 are processed on each ear to be drilled, all the ears to be drilled 110 are arranged in parallel to form corresponding Z rows of coaxial processing holes 111, X is a positive integer, Y and Z are both positive integers greater than 1, adjacent ear plate structures 100 are spaced a first distance apart, adjacent ears to be drilled 110 are spaced a second distance apart, the ratio between the length of the high-precision front beam component and the diameter of the processing hole 111 is greater than 10, the processing device includes: a base 10, the high-precision front beam component is fixedly arranged in the middle of the base 10; positioning and fixing structures 20 are arranged on both sides of the high-precision front beam component for positioning and fixing the high-precision front beam component, The position deviation of the high-precision front beam component on the base 10 is less than 0.02mm; the side support structure 30 is arranged on the side of the positioning and fixing structure 20 away from the high-precision front beam component; the top support structure 40 is arranged on the top of the side support structure 30, the top support structure 40 is staggered with the top of the high-precision front beam component, and a wear-resistant support through hole 41 is coaxially arranged on the top support structure 40 corresponding to the processing hole 111; a large length-to-diameter ratio tool 50 is fixedly arranged on a rotating device on a machine tool, the large length-to-diameter ratio tool 50 passes through the wear-resistant support through hole 41 to form a corresponding processing hole 111 on each ear 110 to be drilled, and the length of the large length-to-diameter ratio tool 50 is greater than or equal to the length of the base 10; the high-precision front beam component, the side support structure 30 and the large length-to-diameter ratio tool 50 are arranged parallel to each other.

[0030] In a possible implementation, after the technicians perform integrated processing on the raw materials, an integrated preliminary front beam component is formed, on which there are a basic frame and multiple groups of ear structures 100. For example, in this embodiment, there are 5 groups of ear structures 100, and each group of ear structures 100 is provided with 2 ears 110 to be drilled. At this time, it is necessary to drill 2 high-precision processing holes 111 on each ear 110 to be drilled to make a high-precision front beam component. In the embodiment of the present application, each ear 110 to be drilled is arranged in parallel, so that the processing holes 111 processed thereon form 2 rows of coaxial processing holes 111. Since the machining accuracy requirements for the above-mentioned two rows of coaxial machining holes 111 in flight equipment are very high, specifically, the coaxiality accuracy of each row of coaxial machining holes is required to be less than 0.02mm, and the diameter deviation of each machining hole 111 is required to be less than 0.02mm. When the diameter of the machining hole 111 is only 10-20mm, the length of the high-precision front beam component exceeds 500mm, that is, the length-to-diameter ratio of the tool required for machining is far more than 10 times, so the use of traditional machining tools and machining methods will not guarantee sufficient machining accuracy and machining stability.

[0031] Based on this, on the one hand, a processing device is designed for the high-precision front beam component to meet its high-precision and large length-to-diameter ratio processing requirements. On the other hand, a new tool is designed and matched with the processing device to achieve high-precision hole processing in the large length-to-diameter ratio scenario.

[0032] Specifically, the processing device includes a base 10, and a high-precision front beam component is fixedly arranged in the middle of the base 10, and is fixed by a positioning and fixing structure 20. Specifically, the positioning and fixing structure 20 has the function of high-precision positioning of the high-precision front beam component to ensure that in the subsequent processing process, the position of the processing hole 111 is in an accurate position, and the processing accuracy thereof can be guaranteed.

[0033] See also Figure 4 In an embodiment of the present invention, the positioning and fixing structure 20 includes a pressing component 21 and a positioning component 22. The pressing component 21 is arranged at the top of the edge of the high-precision front beam component, and is used to fix and press the high-precision front beam component on the base 10; the positioning component 22 is arranged at the top of the pressing component 21, and a plurality of groups of first positioning holes 23 are correspondingly arranged on the base 10, the positioning component 22 and the pressing component 21. Each group of first positioning holes 23 is coaxial in the vertical direction and the processing deviation of the aperture is less than or equal to 0.02mm, the processing deviation of the distance between adjacent groups of first positioning holes 23 is less than or equal to 0.02mm, and the straightness deviation of the first positioning hole 23 in the extension direction of the large length-to-diameter ratio tool 50 is less than or equal to 0.1mm.

[0034] In a possible implementation, after the high-precision front beam component is initially placed on the base 10, it is first pre-tightened by the pressing component 21 to prevent it from shifting, and then the positioning component 22 is fixedly set on the pressing component 21, and multiple groups of first positioning holes 23 are correspondingly set on the pressing component 21, the positioning component 22 and the base 10. For example, in this embodiment, in order to ensure the straightness of the positioning and fixing structure 20 in the axial direction of the high-precision front beam component, two groups of first positioning holes 23 are set on the positioning and fixing structure 20 on one side of the high-precision front beam component. Of course, more than two groups of first positioning holes 23 can also be set on the positioning and fixing structure 20 around the high-precision front beam component to ensure the overall straightness of the positioning and fixing structure 20.

[0035] In the specific configuration process, on the one hand, each group of first positioning holes 23 is coaxial in the vertical direction and the processing deviation of the aperture is less than or equal to 0.02mm. In the positioning process, by inserting positioning pins, preferably expansion positioning pins, into a group of first positioning holes 23, the base 10, the pressing component 21 and the positioning component 22 are accurately positioned on the basis of the above-mentioned high-precision processing deviation; on the other hand, the processing deviation of the distance between adjacent groups of first positioning holes 23 is less than or equal to 0.02mm, and the straightness deviation of the first positioning hole 23 in the extension direction of the large length-to-diameter ratio tool 50 is less than or equal to 0.1mm. Through the above configuration, when the high-precision front beam component is fixedly set on the base by the positioning component 22, it can effectively ensure that the position accuracy and straightness of the high-precision front beam component meet the processing requirements, and can effectively ensure the processing accuracy in the subsequent processing process.

[0036] The processing device provided by the embodiment of the present invention can ensure that the position deviation and straightness deviation of the high-precision front beam component during the processing process meet the requirements of high-precision processing, which is crucial for ensuring the accuracy and coaxiality of the hole. Through the precise positioning and fixing structure and support system, the error caused by the small displacement during the processing is effectively avoided.

[0037] After the high-precision front beam component is accurately fixed on the base 10, a large length-to-diameter ratio tool 50 is prepared to perform hole processing on it. However, in actual application, since the length-to-diameter ratio of the hole is much greater than 10, if the large length-to-diameter ratio tool 50 is directly inserted into the high-precision front beam component for processing, on the one hand, the existing tool manufacturing process cannot guarantee that the straightness of the tool meets the actual high-precision processing requirements; on the other hand, the force during the processing may also cause the tool to produce a slight deformation, resulting in a significant reduction in processing accuracy, thereby failing to meet actual requirements.

[0038] In order to solve the above technical problems, a side support structure 30 is arranged on the side of the positioning and fixing structure 20 away from the high-precision front beam component, and a top support structure 40 is arranged on the top of the side support structure 30. The top support structure 40 and the top of the high-precision front beam component are staggered, and a wear-resistant support through hole 41 is coaxially arranged on the top support structure 40 corresponding to the processing hole 111.

[0039] For detailed configuration, see Figure 5 A second positioning hole (not shown) is provided on the top of the side support structure 30, and a positioning through hole 42 is provided on the top support structure 40 corresponding to the second positioning hole. The top support structure 40 is fixedly arranged on the top of the side support structure 30 through the positioning through hole 42 and the second positioning hole.

[0040] In the actual processing process, the tool 50 with a large length-to-diameter ratio directly passes through the above-mentioned wear-resistant support through hole 41 to process the processing holes 111 on each group of ear structures 100, thereby allowing the wear-resistant support through hole 41 to provide physical support for the tool 50 with a large length-to-diameter ratio, effectively reducing the deformation of the tool 50 with a large length-to-diameter ratio and ensuring processing accuracy; on the other hand, the tool 50 with a large length-to-diameter ratio can be limited by the wear-resistant support hole 41, thereby further ensuring the coaxiality of the processing.

[0041] However, in actual application, since the large length-to-diameter ratio tool 50 will cause friction to the wear-resistant support through hole 41 during the processing, when the usage time reaches a certain length, it will inevitably cause deformation or damage to the inner surface of the wear-resistant support through hole 41, and further lead to the failure of the limiting effect of the large length-to-diameter ratio tool 50 and damage to the surface of the large length-to-diameter ratio tool 50.

[0042] In order to solve the above technical problems, in an embodiment of the present invention, the large length-to-diameter ratio tool 50 includes multiple diameter specification tools, and each large length-to-diameter ratio tool 50 is provided with a corresponding detachable bushing 60, the inner diameter of the bushing 60 is matched with the outer diameter of the corresponding large length-to-diameter ratio tool 50, and the bushing 60 is embedded in the wear-resistant support through hole 41.

[0043] Before processing, first determine the specifications of the large length-to-diameter ratio tool 50 to be used in the current processing. For example, in an embodiment of the present invention, in order to ensure that the final processed hole 111 has sufficient aperture accuracy, coaxiality and straightness, three specifications of large length-to-diameter ratio tools 50 are used to perform processing operations in sequence. For example, in the first processing, a tool with a diameter of 10 mm is used for processing, followed by a tool with a diameter of 13 mm, and finally a tool with a diameter of 15 mm is used for processing to achieve high-precision processing effects.

[0044] During processing, it is necessary to configure a corresponding bushing 60 for each specification of the tool, and then fix it in the wear-resistant support through hole 41. During processing, the large length-to-diameter ratio tool 50 is gradually extended into the bushing 60 to process the processing hole 111 on the high-precision front beam component. During the processing, on the one hand, the bushing 60 limits and supports the blade part of the large length-to-diameter ratio tool 50 to ensure the precise processing effect of the large length-to-diameter ratio tool 50 on the processing hole 111; on the other hand, the inner surface of the bushing 60 can be coated with lubricating material to effectively reduce the wear of the large length-to-diameter ratio tool 50 on the bushing 60. At the same time, before or during each processing, if it is found that the roughness of the inner surface of the bushing 60 does not meet the high-precision processing requirements, it will be replaced immediately to ensure that the bushing 60 used in each processing meets the high-precision processing requirements, and at the same time effectively avoid the replacement of the top support structure 40, greatly reducing the operating costs of the enterprise.

[0045] Furthermore, in order to avoid the influence of the rotation of the bushing 60 on the tool 50 with a large length-to-diameter ratio during processing, the wear-resistant support through hole 41 is a non-circular through hole, such as but not limited to through holes with circular arc angles, triangular through holes and other regular angular through holes, and special-shaped through holes, and the outer shape of the bushing 60 is matched with the outer shape of the non-circular through hole.

[0046] The above-mentioned angled edge or special-shaped setting can ensure the fixation of the bushing 60, avoid the influence on the tool 50 with a large length-to-diameter ratio during the processing, and ensure the reliability of high-precision processing.

[0047] After completing the above configuration, the high-precision processing of the processing hole 111 of the high-precision front beam component can be started. First, the large length-to-diameter ratio tool 50 is fixedly set on the rotating device on the machine tool, and the rotating device is controlled to rotate at a high speed and move forward, so that the large length-to-diameter ratio tool 50 penetrates the wear-resistant support through hole 41 and the bushing 60, and processes each ear 110 to be drilled under the constraint and support of the bushing 60 to form a processing hole 111. Since the machine tool and the rotating device thereon are large-scale equipment, they will inevitably not be able to run within the processing range of the high-precision front beam component during the processing process, which makes the length of the large length-to-diameter ratio tool 50 necessarily greater than or equal to the length of the base.

[0048] In the embodiments of the present invention, see Figure 6The large length-to-diameter ratio tool 50 includes a tool head 51 and a tool handle 52, the tool head 51 includes a blade 511 and a support portion 512, the length of the blade 511 is greater than the thickness of the ear 110 to be drilled, and is less than the sum of the second distance and the thickness of the ear 110 to be drilled; the total length of the support portion 512 and the tool head 511 is greater than the length of each group of ear structure 100, and is less than Y times the sum of the thickness of the ear 110 to be drilled, the first distance and the second distance; the tool head 51 and the tool handle 52 are welded and fixed.

[0049] In the specific implementation process, a cutter head 51 made of cemented carbide is first used, for example, the cemented carbide is a titanium carbide alloy with a hardness greater than 91HRA, and the cutter head 51 includes a blade 511 and a support portion 512. In the embodiment of the present invention, in order to ensure the straightness of the processing hole 111, the cutter head 51 is preferably a reamer, wherein the blade 511 is an alloy blade to maximize and ensure the cutting strength of the tool, wherein the length configuration of the blade 511 can ensure that it penetrates the processing hole 111 at one time, so that each processing hole 111 is punched with high precision. At the same time, during the processing process, the total length configuration of the support portion 512 and the blade 511 enables the blade 511 to complete the processing operation of the first processing hole 111, and the subsequent support portion 512 can immediately cooperate with the bushing 60 to form a support and limit effect on the blade 511, so as to ensure that the straightness and coaxiality of the blade 511 in the process of processing the second processing hole 111 meet the high-precision processing requirements.

[0050] Finally, since the cutter head 51 is able to ensure high-precision processing of the processing hole 111, there is no high-precision configuration requirement for the handle 52. Therefore, the handle 52 is made of ordinary steel and welded to the cutter head 51. It should be noted that the welded cutter head 51 and handle 52 should have basic straightness, for example, at least a straightness of 0.5-1mm, which will not be elaborated here.

[0051] However, in the actual processing process, although the cutter head 51 of the tool 50 with a large length-to-diameter ratio is limited and supported by the bushing 60 and the wear-resistant support through hole 41 to ensure sufficient processing accuracy, at the machine tool end, the end of the tool handle 52 is fixedly connected to the rotating device on the machine tool to control the rotational cutting action of the tool 50 with a large length-to-diameter ratio. Since the tool handle 52 is long and has a low processing accuracy, there must be a certain amplitude of vibration at the end of the tool handle 52 where the machine tool is located. The existing connection methods between the tool and the machine tool are all fixed connections. Therefore, the traditional connection methods either cause the machine tool to exert too much force on the tool, resulting in greater wear on the bushing 60, greatly reducing the service life of the bushing 60; or cause the machine tool to exert too much force on the tool handle 52, resulting in excessive deformation strength and frequency, which can cause the risk of fracture or even breakage of the tool 50 with a large length-to-diameter ratio in a short time.

[0052] In order to solve the above technical problems, in an embodiment of the present invention, a universal connector 70 is arranged between the tool 50 with a large length-to-diameter ratio and the rotating device. The universal connector greatly improves the freedom of movement of the tool handle 52, allowing a certain position deviation between the end of the tool handle 52 and the rotating device of the machine tool in any direction during the processing, while maintaining a continuous and stable operating state. On the one hand, this effectively reduces the deflection force exerted on the tool head 51 by the straightness deviation of the tool handle 52, thereby improving the stability of the tool head 51 during the processing. On the other hand, it effectively improves the machine tool's compatibility with the straightness deviation of the tool handle 52, reduces the high-frequency force of the machine tool on the tool handle 52, and improves the service life of the tool handle 52.

[0053] Preferably, the universal connector 70 includes a first connecting sleeve 71, a second connecting sleeve 72 and a spherical connector 73, the first connecting sleeve 71 includes a first groove, a first connecting rod is arranged on the end of the first groove, and the first connecting rod is inserted into the spherical connector 73 from the upper and lower ends of the spherical connector 73 in the vertical direction; the second connecting sleeve 72 includes a second groove, a second connecting rod is arranged on the end of the second groove, and the second connecting rod is inserted into the spherical connector 73 from the front and rear ends of the spherical connector 73 in the horizontal direction; the end of the first connecting sleeve 71 away from the spherical connector 73 is fixedly connected to the end of the tool handle 52 away from the tool head, and the end of the second connecting sleeve 72 away from the spherical connector 73 is fixedly connected to the rotating device on the machine tool.

[0054] In actual application, when the rotating device on the machine tool drives the large length-to-diameter ratio tool 50 to rotate for processing, on the one hand, the bushing 60 and the wear-resistant support through hole 41 constrain and support the tool head 51, thereby ensuring the processing accuracy of the processing hole 111; on the other hand, the above-mentioned universal connector 70 can allow the end of the tool handle 52 to "swing" to a certain extent during the processing, thereby effectively ensuring the stability and reliability of the processing process.

[0055] Based on this, in an embodiment of the present invention, in order to ensure sufficient stability and reliability of the processing, the length of the first connecting sleeve 71 and the second connecting sleeve 72 is determined based on the length and straightness of the tool handle 52. Specifically, in one embodiment, the length of the tool handle 52 is 1m, and its straightness is 5mm, then the maximum swing amplitude of its end can be determined to be 5mm. According to the first connecting sleeve 71 and the second connecting sleeve 72 in the processing process, the first connecting sleeve 71 is regarded as an axial rotation, and the maximum diameter of the second connecting sleeve 72 that can be annularly rotated under the action of the spherical connector 73 should be greater than or equal to 5mm. Based on this, the length of the first connecting sleeve 71 and the second connecting sleeve 72 can be determined. Thereby, the sufficient stability and reliability of the large length-to-diameter ratio tool 50 in the processing process can be fully guaranteed, the processing accuracy of the processing hole 111 can be guaranteed, the wear degree of the large length-to-diameter ratio tool 50 and the bushing 60 can be reduced, and their service life can be increased.

[0056] Through the above design, a universal connector 70 with a simple structure and high freedom of movement is provided, which greatly reduces the procurement cost of the enterprise and meets the actual processing needs of the enterprise.

[0057] At the same time, the configuration of the above-mentioned universal connector 70 greatly reduces the processing accuracy requirements for the tool handle 52, allowing the enterprise to configure a tool handle 52 with conventional straightness accuracy to make the required large length-to-diameter ratio tool 50, avoiding the customization or procurement cost of a high-straightness accuracy tool handle, thereby greatly reducing the enterprise's operating costs and meeting the actual needs of the enterprise.
