Detailed Implementation

[0062] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0063] like Figure 1 As shown, a multi-station machining method for a rudder module is proposed according to a first aspect of the embodiments of this application, comprising:

[0064] Step S110: Align the blank according to the distribution of the servo board allowance.

[0065] It is understandable that, such as Figure 4 and Figure 5 The diagram shows a schematic of the servo housing, which has four servo plates. The servo wing mechanism can be mounted on these servo plates. The servo plates are arranged around the smaller-diameter end of the servo housing. By checking the dimensions of the blank, the allowance distribution at the servo plates can be determined, allowing for blank alignment and ensuring the accuracy of subsequent machining dimensions.

[0066] Step S120: Clamp the aligned blank and use the cutting system 230 to perform rough machining on multiple servo boards simultaneously.

[0067] Understandably, after aligning the blank, it can be clamped in machining center 200, and multiple servo plates can be rough-machined simultaneously using cutting system 230. Specifically, multiple cutting systems 230 are provided to ensure that each servo plate has a corresponding cutting system 230. The angles between the four servo plates in the servo housing and the central axis of the servo housing are equal, so that the four servo plates are evenly arranged around it. Correspondingly, four cutting systems 230 are provided, each corresponding to one of the four servo plates, so that each cutting system 230 can simultaneously rough-machine the nearest servo plate. The rough-machining process can remove a large amount of excess material from the servo plates, leaving a smaller machining allowance for the finishing process, thereby significantly shortening the rough-machining time and improving machining efficiency.

[0068] Step S130: Use the cutting system 230 to simultaneously finish multiple servo boards after rough machining to obtain servo boards that meet the design dimensions.

[0069] Understandably, after rough machining of multiple servo boards on the blank, the cutting system 230 simultaneously performs finish machining on the rough-machined servo boards. This finish machining removes any remaining small allowances from the servo boards, allowing them to be machined to their designed dimensions simultaneously. This significantly shortens the finish machining process time and improves machining efficiency.

[0070] It should be noted that the material used for the control cabin described in this application is chopped fiber molded fiberglass. Chopped fiber molded fiberglass is an excellent thermal protection material with characteristics such as lightweight, high temperature resistance, electrical insulation, and good comprehensive performance, which can meet the application needs of the aviation and aerospace fields.

[0071] In some examples, the steps of aligning the blank according to the servo plate allowance distribution of the blank include: placing the blank on the turntable of the machining center 200, aligning the inner circle end face of the blank with the servo plate to a first preset value to obtain the first alignment position of the blank; aligning the axial runout of the blank to a second preset value to obtain the second alignment position of the blank; and aligning the outer circumferential runout of the blank to a third preset value to obtain the clamping position of the blank.

[0072] Understandably, the runout of the blank's inner end face, outer circumferential runout, and axial runout can be corrected based on the distribution of the servo plate allowance. Specifically, the large end of the blank can be placed on the worktable 220 of the machining center 200, with the end containing the servo plate facing upwards. A dial indicator can be used to detect the runout of the inner end face of the blank on the side containing the servo plate, and adjustments can be made based on the detection results to correct the inner end face runout to a first preset value. This ensures that the distance between the position of each servo plate and its corresponding cutting center is equal. Subsequently, a dial indicator can be used to detect the axial runout of the blank, and adjustments can be made based on the detection results. Specifically, if the axial runout exceeds a second preset value, shims can be placed at the large end of the blank to correct the axial runout to the second preset value. Subsequently, a dial indicator can be used to detect the circumferential runout of the blank, and adjustments can be made based on the detection results. Specifically, when the circumferential runout exceeds the third preset value, the worktable 220 can be rotated to adjust the circumferential position of the blank and correct the runout until it reaches the third preset value. At this point, the machining position of each servo plate on the blank and the distance to its corresponding cutting system 230 are equal. After all the above correction operations, the blank is in the clamping position.

[0073] In some examples, the first preset value is less than or equal to 0.1 mm; the second preset value is less than or equal to 0.1 mm; and the third preset value is greater than 3 mm and less than or equal to 5 mm.

[0074] Understandably, the first preset value can be set to less than or equal to 0.1 mm to ensure that the inner diameter runout of the end face of the blank with the servo plate meets the machining requirements, thus ensuring that the servo plate is machined to the design dimensions. The second preset value can be set to less than or equal to 0.1 mm to ensure that the axial runout of the blank meets the machining requirements, thus ensuring that the servo plate is machined to the design dimensions. The third preset value is greater than 3 mm and less than or equal to 5 mm to ensure that the outer circumferential runout of the blank meets the machining requirements, thus ensuring that the servo plate is machined to the design dimensions.

[0075] In some examples, such as Figure 2 As shown, the cutting system 230 includes: a robotic arm 231, which is disposed in the machining center 200 and has at least five degrees of freedom; a cutter shaft 232, which is connected to the robotic arm 231; and a cutting tool 233, which is connected to the cutter shaft 232 and is used to cut the servo plate.

[0076] Understandably, the cutting system 230 may include a robotic arm 231, a tool axis 232, and a cutting tool 233. The robotic arm 231 is located within the machining center 200, the tool axis 232 is connected to the robotic arm 231, and the cutting tool 233 is mounted on the tool axis 232, cutting the servo plate via the cutting tool 233. The robotic arm 231 has at least five degrees of freedom to adjust the distance between the cutting tool 233 and the servo plate in response to the CNC program. This configuration allows the machining process and toolpath for the servo plate to be determined based on the design dimensions of the servo housing, enabling the creation of a CNC program. The robotic arm 231, responding to the CNC program, moves the cutting tool 233 to cut the blank according to the planned toolpath, thus machining the servo plate. Furthermore, the controller 240 can simultaneously drive four robotic arms 231 to machine the corresponding servo plates according to their respective toolpaths, achieving synchronous machining.

[0077] In some examples, the multi-station machining method for the servo housing also includes: detecting the dimensions of the multiple servo plates after finishing.

[0078] Understandably, after the servo board is precision machined, its dimensions can be inspected to determine if it has been machined to the design dimensions. If some areas of the servo board do not meet the design dimensions, additional machining is required to ensure the quality of the parts.

[0079] like Figures 2 to 5As shown, a machining center 200 according to the second aspect of this application is used for a multi-station machining method of rudder compartments applied to any of the above-mentioned technical solutions, comprising: a base 210; a worktable 220 connected to the base 210 for placing the rudder compartment blank; a cutting system 230 disposed on the worktable 220 for cutting the blank; and a controller 240 connected to the cutting system 230 for controlling the operation of the cutting system 230 according to a CNC program; wherein, multiple cutting systems 230 are provided for simultaneously cutting multiple rudder plates of the blank, and the controller 240 can control the multiple cutting systems 230 to operate independently.

[0080] It is understood that the multi-station machining method for the rudder compartment described in any of the above technical solutions can be implemented through the machining center 200. Specifically, the machining center 200 is equipped with a base 210, a worktable 220, a cutting system 230, and a controller 240. The base 210 can house the pipelines of the machining center 200 to protect them, prevent excessive pipeline arrangement, and ensure the cleanliness of the machining site. The worktable 220 is connected to the base 210 and supports the workpiece. The rudder compartment blank can be placed on the worktable 220, and the cutting system 230 is located on the worktable 220. The cutting system 230 processes the blank to machine multiple servo plates on the upper surface of the rudder compartment. The multiple servo plates are arranged in a circular, spaced-apart arrangement on the upper surface. Four servo plates can be provided, corresponding to four cutting systems 230, to simultaneously machine four servo plates, thereby improving machining efficiency and significantly reducing machining time. In addition, four servo plates are machined simultaneously to ensure that the stress release of the servo plates is balanced and to reduce the deformation of the servo housing.

[0081] Understandably, the machining process and tool path for the servo board can be determined based on the design dimensions of the servo housing, and a CNC program can be written and input into the controller 240. The controller 240 controls the tool paths of different cutting systems 230 according to the CNC program, so as to simultaneously machine the servo board corresponding to each cutting system 230. Furthermore, the controller 240 can control multiple cutting systems 230 to operate independently, so as to ensure the machining accuracy of each servo board according to its specific condition.

[0082] In some examples, such as Figure 3 As shown, the cutting system 230 includes: a robotic arm 231 connected to the worktable 220, the robotic arm 231 having at least five degrees of freedom, the robotic arm 231 being connected to the controller 240; a cutter shaft 232 connected to the robotic arm 231; and a cutting tool 233 connected to the cutter shaft 232 for cutting the servo motor plate.

[0083] Understandably, the cutting system 230 includes a robotic arm 231, a cutter shaft 232, and a cutting tool 233. The robotic arm 231 is mounted on the worktable 220, the cutter shaft 232 is connected to the robotic arm 231, and the cutting tool 233 is mounted on the cutter shaft 232, cutting the servo plate via the cutting tool 233. The robotic arm 231 has at least five degrees of freedom to adjust the distance between the cutting tool 233 and the servo plate in response to the CNC program. This configuration allows the machining process and toolpath for the servo plate to be determined based on the design dimensions of the servo housing, enabling the creation of the CNC program. The multiple degrees of freedom of the robotic arm 231 can accommodate various toolpaths, driving the cutting tool 233 to move, thus making the toolpath design more flexible. The robotic arm 231 can drive the cutter shaft 232 and the cutting tool 233 to cut the blank according to the planned toolpath, thereby machining the servo plate. Furthermore, the controller 240 can simultaneously drive four robotic arms 231 to machine the corresponding servo plates according to their respective toolpaths, achieving synchronous machining. The tool 233 can be changed according to the needs of roughing and finishing processes to ensure machining accuracy.

[0084] In some examples, such as Figure 3 As shown, the robotic arm 231 includes: a linear guide rail 2311 disposed on the worktable 220; a support rod 2312 slidably connected to the linear guide rail 2311; a first rotating shaft 2313 rotatably connected to the free end of the support rod 2312; a second rotating shaft 2314 rotatably connected to the free end of the first rotating shaft 2313; a telescopic rod 2315 connected to the free end of the second rotating shaft 2314; a third rotating shaft 2316 connected to the telescopic end of the telescopic rod 2315; and a cutter shaft 232 connected to the free end of the third rotating shaft 2316.

[0085] Understandably, the robotic arm 231 may be equipped with a linear guide rail 2311, a support rod 2312, a first rotating shaft 2313, a second rotating shaft 2314, a telescopic rod 2315, and a third rotating shaft 2316. The support rod 2312 is slidably connected to the linear guide rail 2311; the first rotating shaft 2313 can rotate relative to the support rod 2312; the second rotating shaft 2314 can rotate relative to the first rotating shaft 2313; the telescopic rod 2315 is connected to the free end of the second rotating shaft 2314 and can extend out of or retract into the second rotating shaft 2314; the third rotating shaft 2316 can rotate relative to the telescopic end of the telescopic rod 2315; and the cutter shaft 232 is connected to the free end of the third rotating shaft 2316. With this configuration, the robotic arm 231 can respond to the CNC program and adjust the sliding distance of the support rod 2312, the rotation angle of the first rotating shaft 2313, the rotation angle of the second rotating shaft 2314, the length of the telescopic rod 2315, and the rotation angle of the third rotating shaft 2316 according to the tool path of the CNC program, thereby adjusting the distance between the tool 233 and the workpiece so that the tool 233 can cut the workpiece according to the tool path of the CNC program.

[0086] In some examples, such as Figure 2 As shown, the machining center 200 also includes: a dust cover 250, which is installed on the workbench 220 and has a dustproof space inside; and a door panel 260, which is connected to the dust cover 250 and is used to open or cover the dust cover 250.

[0087] It is understood that the machining center 200 is also equipped with a dust cover 250 and a door panel 260. The dust cover 250 covers the worktable 220, forming a dustproof space between the dust cover 250 and the worktable 220. Machining parts within this dustproof space prevents foreign objects from entering the worktable 220 and affecting machining. The rudder compartment described in this application is made of chopped fiber molded fiberglass, which easily generates debris during machining. The dust cover 250 prevents debris from splashing during cutting, protecting the machining environment. The door panel 260 is connected to the side of the dust cover 250. Operating the door panel 260 opens the dust cover 250, allowing the user to place or remove parts from the worktable 220. After removing or placing the parts, the door panel 260 can be operated to cover the dust cover 250, ensuring a sealed dustproof space within the dust cover 250.

[0088] Understandably, the machining center 200 is also equipped with a dust removal device 270, which can collect the dust generated by the cutting tool 233 during the cutting of the blank, preventing the dust from escaping into the dustproof space. The dust removal device 270 can be a vacuum cleaner or other device that can generate suction to suck up and collect the dust.

[0089] In some examples, such as Figure 2 As shown, the machining center 200 further includes: an air source for storing inert gas; a cooling device 280 connected to the air source for reducing the temperature of the inert gas; and a conveying pipeline, one end of which is connected to the cooling device 280 and the other end of which is connected to the dustproof space.

[0090] Understandably, the cooling device 280 can supply inert gas from the air source to the cooling device 280 for cooling, and then supply the low-temperature inert gas to the dustproof space through the delivery pipeline, thereby reducing the temperature of the dustproof space, so as to ensure that the tool 233 is cooled when cutting the blank, and ensure that the tool 233 can continuously and stably cut the blank.
