Description

Technical Field

[0001] This invention relates to the technical field of hole making on five-axis machine tools, and more particularly to a clamping device and a laser measurement hole making system for wing hanging hole making operations. Background Technology

[0002] In the assembly and manufacturing of aerospace structural components such as wing hangers, high-precision hole drilling is a crucial step in ensuring connection quality and structural safety. Because components have strict requirements for the positional accuracy, perpendicularity, and depth of holes, traditional manual or semi-automatic hole drilling methods often struggle to simultaneously meet the demands for high efficiency and high precision.

[0003] In existing technologies, clamping equipment is often used in conjunction with multi-axis CNC machine tools for hole making. Since the clamping equipment uses a clamping method that directly fixes the wing hanger and the rotary table with bolts, there will inevitably be dimensional deviations between different wing hangers. This makes it difficult for the bolt connection to stably adapt to all wing hangers, resulting in reduced connection stability of the wing hangers. As a result, the wing hangers are prone to shifting due to stress during the hole making process, reducing the hole making accuracy and quality.

[0004] Furthermore, conventional hole-making processes involve a single feed to complete the drilling, lacking the ability to detect and adaptively correct the actual hole position normal during processing, making it difficult to guarantee hole perpendicularity. Additionally, factors such as material springback, clamping stress release, or equipment thermal deformation can cause deviations between the actual hole depth and the target value. Conventional depth measurement methods often rely on machine tool encoder feedback, making it impossible to perform in-situ measurement and verification of the true hole depth, thus hindering precise depth control.

[0005] Because the wing hanger needs to be indexed and rotated during processing, and holes are drilled in multiple directions, it is also subject to forces in multiple directions, which can easily lead to clamping failure or positioning misalignment, and also reduce the drilling accuracy. Summary of the Invention

[0006] The technical problem to be solved:

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a clamping device and a laser measurement hole-making system for wing suspension hole-making operations. It solves the technical problem that in the conventional clamping method of the prior art, the connection stability of the wing suspension is reduced, so the wing suspension is prone to displacement due to force during the hole-making process, which reduces the hole-making accuracy and hole-making quality.

[0008] Technical solution:

[0009] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0010] In a first aspect, the present invention provides a clamping device for drilling holes in wing hangers, suitable for clamping wing hangers along the length direction of the wing hanger. The small end and large end of the wing hanger each have a plurality of first connecting ears extending forward and backward and a plurality of second connecting ears extending along the length direction of the wing hanger. The clamping device includes a rotary table, a first intermediate assembly, and a second intermediate assembly. There are two rotary tables, which are coaxially arranged relative to each other. The first intermediate assembly and the second intermediate assembly are detachably and fixedly connected to the corresponding first connecting ears and the corresponding second connecting ears to form an assembly. The first intermediate assembly and the second intermediate assembly are detachably and fixedly connected to the corresponding rotary table. The second intermediate assembly has a front-to-back extending end plate, on which two sets of connecting areas are formed with a front-to-back spacing. The clamping device also includes a compensation insert, which can be selectively inserted between the first intermediate assembly and the first connecting ears, and can also be selectively inserted between the connecting areas and the rotary table to compensate for the fluctuation of the corresponding spacing.

[0011] The technical solution of the present invention also includes a mounting frame fixedly connected to two rotary tables. The first intermediate component and the second intermediate component are fixedly connected to the rotary tables through corresponding mounting frames. The mounting frame has a female positioning plate extending along the wing suspension length direction. The first intermediate component and the second intermediate component both have a female positioning plate extending along the wing suspension length direction. The invention also includes two sets of positioning components that correspond one-to-one with the first intermediate component and the second intermediate component. Each positioning component includes a female positioning part and a female positioning part that cooperate with each other. The two parts are fixedly connected to the corresponding female positioning plate and the female positioning plate, and the two parts can cooperate with each other and be locked along the normal direction of the female positioning plate.

[0012] The technical solution of the present invention also includes a clamping assembly, which includes two auxiliary top blocks. The two auxiliary top blocks are detachably and fixedly connected to the two sides of the mother positioning plate along the front and rear directions of the wing suspension. The opposing surfaces of the two auxiliary top blocks form a U-shaped groove with the mother positioning plate. The two auxiliary top blocks can move closer to each other or further away from each other. When the two auxiliary top blocks move closer to each other, they can clamp the corresponding sub-positioning plate.

[0013] When the two auxiliary top blocks move away from each other, the corresponding sub-positioning plates can be released.

[0014] The technical solution of the present invention also includes a connecting device, which includes a bolt assembly. The first intermediate assembly has a first connecting plate extending along the front and rear direction of the wing suspension. The first connecting plate and the first connecting lug, as well as the second intermediate assembly and the second connecting lug, are locked together by corresponding bolt assemblies.

[0015] In the technical solution of the present invention, the connecting device further includes a separation washer, which is located between the bolt assembly and the corresponding first connecting ear or second connecting ear, so as to separate the first connecting ear and the second connecting ear from the corresponding bolt assembly.

[0016] In the technical solution of the present invention, the connecting device further includes a wrench, which is detachably and fixedly connected to the nut of the bolt assembly and extends radially along the nut, and is suitable for applying a rotational torque to the nut.

[0017] In the technical solution of the present invention, the second intermediate component includes an upper connecting seat and a lower connecting seat. The upper connecting seat has a sub-positioning plate; the lower connecting seat has an end plate, and the end plate is locked to the mounting frame by two sets of connecting devices.

[0018] In the technical solution of the present invention, there are two first connecting ears and three second connecting ears.

[0019] In the technical solution of the present invention, the hole-making device includes a drill bit and a five-axis oscillating head assembly, the five-axis oscillating head assembly being adapted to drive the drill bit to perform a hole-making operation;

[0020] The measuring device, supported by the five-axis oscillating head assembly, is suitable for measuring the position and direction of the normal to the surface to be drilled on the wing, as well as the depth of the drilled holes;

[0021] The hole-making device can make holes multiple times on the surface to be drilled, and the depth of the next hole is greater than the depth of the previous hole. Before the first hole making at a hole position, the measuring device detects the normal of the surface to be drilled. Before and after the remaining hole making at a hole position, the measuring device detects the normal of the surface to be drilled and the drilling depth.

[0022] Beneficial effects:

[0023] The beneficial effects of the present invention are as follows: The clamping device and laser measurement hole-making system for wing mounting hole making of the present invention have two coaxially arranged rotary tables that can ensure that the angle can be switched around a unified rotation center during the indexing hole making process, thereby ensuring the positional accuracy and repeatability of the hole position in the circumferential direction, and also providing a basis for omnidirectional hole making for wing mounting in conjunction with a five-axis machining head.

[0024] The small end of the wing pylon has multiple first connecting lugs extending along the fore-and-aft direction of the wing pylon, while the large end has multiple second connecting lugs extending along the length of the wing pylon. These first and second connecting lugs are not additional structures for clamping, but rather connection structures for the wing pylon to be assembled onto the aircraft. Using this connection structure for clamping eliminates the need to alter the overall structure of the wing pylon, ensuring its structural stability.

[0025] Because the extension directions of the first connecting lug and the end plate selected on the wing sling intersect each other, after clamping and locking, the wing sling can reliably bear the force along the length of the wing sling and the force along the front-to-back direction of the wing sling, thus ensuring the clamping stability of the wing sling.

[0026] The assembly can be completed in advance at other stations far away from the drilling station, which improves the clamping efficiency between the wing hanger and the turntable, thereby improving the drilling efficiency.

[0027] This clamping device for drilling holes in wing hangers cleverly utilizes existing structural features on the wing hanger body to achieve efficient and stable clamping and positioning. This not only avoids additional machining or structural modifications to the part itself but also significantly improves the overall accuracy and efficiency of the drilling operation. The small end of the wing hanger has multiple first connecting lugs extending along its fore-and-aft direction, while the large end is equipped with multiple second connecting lugs extending forward along its length. These are the standard interfaces used to connect the wing hanger to the fuselage or other structures during the overall assembly process. The clamping device is designed based on the existing connection structure, using connecting devices to detachably and securely connect the first intermediate component to the first connecting lug, and the second intermediate component to the second connecting lug, thereby constructing a rigid and accurately positioned assembly.

[0028] During the indexing and drilling process, the assembly can precisely switch angles around the coaxial center to ensure consistent and repeatable positioning accuracy of each hole in the circumferential direction. It can work in conjunction with the multi-degree-of-freedom motion capabilities of five-axis machining equipment to achieve high-precision drilling of multi-angle holes for wing mounting, effectively avoiding cumulative errors caused by datum offset or repeated clamping.

[0029] In actual manufacturing, the connecting lugs of wing slings from different batches or individual units may have slight spatial deviations, especially in the spacing differences along the length and longitudinal direction. By selectively inserting compensating inserts of different thicknesses between the first intermediate component and the first connecting lug, or between the connecting area and the turntable, these spacing fluctuations can be flexibly adjusted and eliminated, ensuring a tight fit between the clamping contact surfaces. This significantly improves the overall system's positioning robustness and process tolerance without sacrificing clamping efficiency. In particular, the end plate has two sets of connecting areas spaced apart, which not only enhances the overall structural rigidity but also provides the possibility of multi-point constraints during clamping, effectively suppressing deformation caused by the sling's own weight or processing reaction forces.

[0030] In addition, this clamping solution allows the assembly assembly to be pre-assembled at an auxiliary station far from the main drilling area, which greatly shortens the non-machining waiting time of the main equipment, optimizes the production cycle, and improves the utilization rate of high-end CNC equipment.

[0031] In summary, this clamping device achieves high-precision, high-efficiency, and high-stability indexing and hole-making clamping for wing mounting through multiple technical means such as structural reuse, unified rotation reference, spacing compensation mechanism, and assembly process optimization, thereby improving hole-making efficiency and accuracy.

[0060] To better explain and facilitate understanding of this invention, the following description is provided in conjunction with the appendix. Figures 1-13 The present invention will be described in detail through specific embodiments. In this document, directional terms such as "upper" and "lower" are used interchangeably with other directional terms. Figure 3 The orientation is used as a reference.

[0061] Example 1:

[0062] Reference Figures 1-9An embodiment of the present invention provides a clamping device 1 for indexing and drilling operations on a wing hanger 100, suitable for clamping the wing hanger 100 along its length. The small end and large end of the wing hanger 100 respectively have multiple first connecting ears 200 extending forward and backward and multiple second connecting ears 300 extending along the length of the wing hanger 100. The clamping device 1 includes a rotary table 101, a first intermediate component 103 and a second intermediate component 104. There are two rotary tables 101, which are coaxially arranged relative to each other. The first intermediate component 103 and the second intermediate component 104 are connected to the corresponding first connecting ears. The ear 200 and the second connecting ear 300 are detachably and fixedly connected to form an assembly. The first intermediate component 103 and the second intermediate component 104 are detachably and fixedly connected to the corresponding rotary table 101. The second intermediate component 104 has a front-to-back extending end plate 1041, on which two sets of connecting areas are formed at a front-to-back interval. The clamping device 1 also includes a compensation insert 105, which can be selectively inserted between the first intermediate component 103 and the first connecting ear 200, and can also be selectively inserted between the connecting area and the rotary table 101 to compensate for the fluctuation of the corresponding spacing.

[0063] In this embodiment, the two coaxially arranged rotary tables 101 can ensure that the angle can be switched around a unified rotation center during the indexing and hole making process, thereby ensuring the positional accuracy and repeatability of the hole in the circumferential direction, and also providing a basis for omnidirectional hole making of the wing hanger 100 in conjunction with the five-axis machining head.

[0064] The wing pylon 100 has multiple first connecting ears 200 extending along the fore-and-aft direction at its small end, and multiple second connecting ears 300 extending along the length direction at its large end. The first connecting ears 200 and second connecting ears 300 are not additional structures for clamping, but rather connection structures for assembling the wing pylon 100 onto the aircraft. Using this connection structure for clamping eliminates the need to alter the overall structure of the wing pylon 100, ensuring its structural stability.

[0065] Since the extension directions of the first connecting lug 200 and the end plate 1041 selected on the wing sling 100 intersect each other, after clamping and locking, the wing sling 100 can reliably bear the force along the length of the wing sling 100 and the force along the front-rear direction of the wing sling 100, thereby ensuring the clamping stability of the wing sling 100.

[0066] The assembly can be completed in advance at other stations far away from the drilling station, which improves the clamping efficiency between the wing hanger 100 and the rotary table 101, thereby improving the drilling efficiency.

[0067] The clamping device 1 for indexing and drilling operations on the wing pylon 100 cleverly utilizes the existing structural features of the wing pylon 100 body to achieve efficient and stable clamping and positioning. This not only avoids additional processing or structural modifications to the part body but also significantly improves the overall accuracy and efficiency of the drilling operation. The small end of the wing pylon 100 is provided with multiple first connecting ears 200 extending along its front-rear direction, while the large end is equipped with multiple second connecting ears 300 extending forward along its length direction. These two are originally standard interfaces used by the wing pylon 100 to connect with the fuselage or other structures during the overall assembly process. The clamping device 1 is designed based on the existing connection structure. The first intermediate component 103 is detachably and fixedly connected to the first connecting ears 200, and the second intermediate component 104 is detachably and fixedly connected to the second connecting ears 300 through the connecting device 102, thereby constructing an assembly with good rigidity and accurate positioning.

[0068] During the indexing and drilling process, the assembly can precisely switch angles around the coaxial center to ensure consistent and repeatable positioning accuracy of each hole in the circumferential direction. It can work in conjunction with the multi-degree-of-freedom motion capabilities of five-axis machining equipment to achieve high-precision drilling of over 100 angle holes on wing suspensions, effectively avoiding cumulative errors caused by datum offsets or repeated clamping.

[0069] In actual manufacturing, the connecting ears of different batches or individual wing suspenders 100 may have slight deviations in spatial position, especially in the spacing differences in the length and longitudinal directions. By selectively inserting compensating inserts 105 of different thicknesses between the first intermediate component 103 and the first connecting ear 200, or between the connecting area and the turntable 101, these spacing fluctuations can be flexibly adjusted and eliminated, ensuring a tight fit between the clamping contact surfaces. This significantly improves the positioning robustness and process tolerance of the overall system without sacrificing clamping efficiency. In particular, the end plate 1041 has two sets of connecting areas spaced apart, which not only enhances the overall rigidity of the structure but also provides the possibility of multi-point constraints during clamping, effectively suppressing deformation caused by the suspender's own weight or processing reaction force.

[0070] In addition, this clamping solution allows the assembly assembly to be pre-assembled at an auxiliary station far from the main drilling area, which greatly shortens the non-machining waiting time of the main equipment, optimizes the production cycle, and improves the utilization rate of high-end CNC equipment.

[0071] In summary, the clamping device 1 achieves high-precision, high-efficiency, and high-stability indexing and hole-making clamping of the wing sling 100 through multiple technical means such as structural reuse, unified rotation reference, spacing compensation mechanism, and assembly process optimization, thereby improving hole-making efficiency and accuracy.

[0072] More specifically, the compensation insert 105 is available in various thicknesses such as 0.1 mm, 0.2 mm, and 0.5 mm. Operators can flexibly select the appropriate thickness insert for filling and compensation based on the actual measured spacing deviation. In this way, not only can local spacing caused by manufacturing tolerances or assembly deformation be eliminated, but also the two connection points can achieve a nearly uniform fit and stress level after the connection device 102 is locked.

[0073] More specifically, there are two first connecting ears 200 and three second connecting ears 300. The first connecting ears 200 are spaced apart, and the second connecting ears 300 are arranged in parallel in a triangular layout.

[0074] Two first connecting lugs 200, spaced apart front to back, extend along the width plane and are arranged perpendicular to the main axis of the wing pylon 100, thus forming effective bending and torsional constraints in the length direction. When the first intermediate component 103 is fixed to the two first connecting lugs 200 via the connecting device 102, it not only restricts the translational freedom of the wing pylon 100 in the length direction but also effectively suppresses the rotational tendency around the width and height axes, thereby providing longitudinal rigid support for the overall clamping.

[0075] The three second connecting lugs 300 extend forward in parallel along the length of the wing pylon 100 and are arranged in a triangle, forming a stable three-point positioning reference. These three points define a plane, ensuring that the attitude of the wing pylon 100 is uniquely determined in both the width and height directions, avoiding clamping deformation or positioning drift caused by over- or under-positioning. Simultaneously, the triangular layout also evenly distributes the clamping force, preventing localized stress concentration and improving structural safety during clamping.

[0076] The two first connecting lugs 200 and the three second connecting lugs 300 help to further improve the stability of the wing sling 100 after it is clamped.

[0077] Example 2:

[0078] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0079] The clamping device 1 also includes a mounting bracket 106 fixedly connected to two rotary tables 101. The first intermediate component 103 and the second intermediate component 104 are fixedly connected to the rotary tables 101 through the corresponding mounting bracket 106. The mounting bracket 106 has a female positioning plate 1061 extending along the length direction of the wing sling 100. The first intermediate component 103 and the second intermediate component 104 both have a female positioning plate 1040 extending along the length direction of the wing sling 100. The clamping device 1 also includes two sets of positioning components 107 corresponding one-to-one with the first intermediate component 103 and the second intermediate component 104. Each positioning component 107 includes a female positioning part and a female positioning part that cooperate with each other. The two parts are fixedly connected to the corresponding female positioning plate 1061 and the female positioning plate 1040, and the two parts can cooperate with each other and be locked along the normal direction of the female positioning plate 1061.

[0080] Specifically, the sub-positioning part and the female positioning part can be a cup cone positioner and a cup cone positioner, respectively. The two can provide guidance during the cooperation process, thereby further improving the installation speed between the assembly and the mounting bracket 106. The female positioning plate 1061 and the sub-positioning plate 1040 can be locked together by bolts.

[0081] In this embodiment, the positioning component 107 significantly improves the docking efficiency and spatial positioning accuracy between the first intermediate component 103 and the second intermediate component 104 and the mounting bracket 106.

[0082] Specifically, the mounting bracket 106 has a female positioning plate 1061 extending along the length of the wing sling 100, while the first intermediate component 103 and the second intermediate component 104 are respectively provided with sub-positioning plates 1040 extending in the same direction. The two are in a face-to-face fit-in relationship during assembly. When the first intermediate component 103 and the second intermediate component 104 approach the mounting bracket 106, the sub-positioning part and the female positioning part interlock along the normal direction of the female positioning plate 1061. This not only restricts the degrees of freedom of the first intermediate component 103 and the second intermediate component 104 in the length and longitudinal directions of the wing sling 100, but also effectively eliminates assembly errors caused by manual alignment deviations.

[0083] Furthermore, the sub-positioning part and the mother positioning part preferably adopt a cup-cone positioner and cup-cone positioning seat cooperation form. This structure has the characteristics of self-centering, high repeatability, and good guidance in the field of mechanical assembly. During the installation process, the conical structure first contacts and guides the two parts to align along the ideal path, and then the cup-shaped structure completes the final fitting, which greatly reduces the operator's reliance on assembly skills, shortens the clamping preparation time, and avoids the risk of damage or connection failure caused by misalignment during traditional bolt pre-tightening.

[0084] This positioning structure effectively suppresses errors caused by clamping deviations, improving the hole-making qualification rate and structural assembly matching degree. At the same time, since the positioning component 107 is reusable and has low wear, it also extends the service life of the clamping device 1, reduces maintenance costs, and demonstrates good engineering practicality and economy.

[0085] Example 3:

[0086] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0087] It also includes a clamping assembly 108, which includes two auxiliary top blocks 1081. The two auxiliary top blocks 1081 are detachably and fixedly connected to the two sides of the mother positioning plate 1061 along the front and rear directions of the wing sling 100. The opposing surfaces of the two auxiliary top blocks 1081 form a U-shaped groove with the mother positioning plate 1061. The two auxiliary top blocks 1081 can move closer to each other or further away from each other to selectively clamp the corresponding sub-positioning plate 1040.

[0088] Since the wing sling 100 is subjected to forces in multiple directions during the hole-making process, the clamping assembly 108 can further restrict the degrees of freedom of the wing sling 100 in the front-back direction, making it less prone to displacement when subjected to forces in the width direction, thereby improving the hole-making accuracy.

[0089] The auxiliary top block 1081 and the mounting bracket 106 can be connected by bolts. By tightening or loosening the bolts, the two auxiliary top blocks 1081 can move closer or further apart along the front and rear direction of the wing sling 100, thereby switching between a "clamped state" and a "released state". In the clamped state, the two sides of the U-shaped groove apply a uniform and symmetrical clamping force to the sub-positioning plates 1040 of the first intermediate component 103 and the second intermediate component 104 to achieve rigid locking. In the release state, sufficient space is provided for the quick loading and unloading of the sub-positioning plates 1040 of the first intermediate component 103 and the second intermediate component 104.

[0090] Drilling and countersinking operations not only generate feed forces along the tool axis, but also introduce significant lateral forces in the front-to-back direction due to cutting vibrations, material springback, or tool runout. If the clamping system lacks effective constraints, the first intermediate component 103, the second intermediate component 104, and even the entire suspension structure may experience minor slippage, elastic deformation, or even chatter, leading to hole position misalignment, out-of-tolerance hole spacing, or decreased hole wall quality. However, the clamping component 108 effectively restricts the degrees of freedom of the first intermediate component 103 and the second intermediate component 104, significantly improving the system's ability to resist lateral disturbances.

[0091] The clamping assembly 108 works in synergy with the aforementioned cup cone positioning structure: the cup cone positioner and the positioning seat first complete the high-precision initial positioning of the first intermediate assembly 103 and the second intermediate assembly 104 in the length and front-back directions, and provide a guiding function to ensure rapid alignment; subsequently, the clamping assembly 108 applies a lateral locking force, and the bolts used to lock the mother positioning plate 1061 and the daughter positioning plate 1040 provide a normal locking force, which enables a stable and reliable connection between the first intermediate assembly 103 and the second intermediate assembly 104 and the mounting bracket 106.

[0092] The auxiliary top block 1081 adopts a detachable connection method, which makes it easy to replace the top block of different sizes or shapes according to the hanging model, thus enhancing the versatility and flexible adaptability of the device.

[0093] Example 4:

[0094] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0095] It also includes a connecting device 102, which further includes a bolt assembly 1022; the first intermediate assembly 103 has a first connecting plate extending in the front-rear direction along the wing sling 100, and the first connecting plate and the first connecting lug 200, as well as the second intermediate assembly 104 and the second connecting lug 300, are all locked together by corresponding bolt assemblies 1022.

[0096] The connecting device 102 also includes a separation washer 1023, which is located between the bolt assembly 1022 and the corresponding first connecting lug 200 or second connecting lug 300, so as to separate the first connecting lug 200 and the second connecting lug 300 from the corresponding bolt assembly 1022.

[0097] In this embodiment, the release washer 1023 is used to physically isolate the bolt head or nut from direct pressing contact with the first connecting lug 200 and the second connecting lug 300, preventing the bolt from causing indentations, scratches, or localized plastic deformation on the surface of the first connecting lug 200 during the tightening process, thus effectively protecting the integrity of the structural surface. Furthermore, the release washer 1023 can evenly distribute the bolt preload, reduce localized stress concentration, and improve the fatigue life of the connection pair.

[0098] Furthermore, since the first connecting lug 200 is arranged along the front-to-back direction of the wing sling and the second connecting lug 300 is arranged along the length of the wing sling 100, the bolt assembly 1022 can withstand the shear force during lateral vibration or lateral loads during the drilling process. Combined with the aforementioned positioning and clamping system, this connection method ensures the positional stability and reliability of the wing sling 100 within the assembly.

[0099] Example 5:

[0100] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0101] The second intermediate component 104 includes an upper connecting seat 1042 and a lower connecting seat 1043. The upper connecting seat 1042 has a sub-positioning plate 1040. The lower connecting seat 1043 has an end plate 1041. The end plate 1041 is locked to the mounting bracket 106 by two sets of connecting devices 102.

[0102] In this embodiment, the second intermediate component 104 is further subdivided into two functional units: the upper connector 1042 and the lower connector 1043, forming a hierarchical and partitioned connection architecture.

[0103] The upper connecting seat 1042 undertakes the positioning and guiding functions. It is provided with a sub-positioning plate 1040 extending along the length of the wing suspension 100, which is used to cooperate with the aforementioned positioning component 107, such as a cup cone positioner, to ensure the initial position accuracy of the entire assembly on the rotary table 101.

[0104] The lower connecting seat 1043 is also clamped together with the corresponding mounting bracket 106 via the connecting device 102. Specifically, the mounting bracket 106 and the end plate 1041 of the lower connecting seat 1043 are spatially parallel and opposite each other. The bolt assembly 1022 passes through the end plate 1041 and the mounting bracket 106 from the front and rear sides respectively, and applies a preload to securely lock the lower connecting seat 1043 onto the mounting bracket 106. This front and rear dual-point clamping layout not only enhances the bending stiffness of the connection interface, but also effectively resists the overturning moment generated by the tool action during the drilling process, preventing the lower connecting seat 1043 from slightly tilting or slipping during processing.

[0105] Two sets of compensating inserts 105 can be selectively inserted into the gaps between the front and rear end plates 1041 and the mounting bracket 106, respectively. Operators can independently select inserts of different thicknesses for targeted compensation based on the measured gap values. This is to compensate for the accumulated tolerances during the manufacturing and assembly process of the wing pylon 100 and its mounting structure. In particular, when there may be slight differences in the actual gaps between the front and rear connection areas, if a connection interface of uniform thickness is forcibly used for locking, it is very easy to cause insufficient local preload or overload, which will affect the overall rigidity or even cause the connection to loosen. This problem can be solved by introducing compensating inserts 105.

[0106] This technical solution avoids bolt loosening or stress concentration at the edge of the connecting plate caused by excessive spacing on one side. It also prevents structural deformation caused by forced clamping, ensuring that the lower connecting seat 1043 maintains a stable posture under dynamic machining loads. Furthermore, this compensation mechanism eliminates the need for repairs or rework of the main structure; adaptation can be quickly achieved simply by replacing standardized inserts, significantly improving the process flexibility and on-site response efficiency of the clamping system.

[0107] Example 6:

[0108] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0109] The connecting device 102 also includes a wrench 1024, which is detachably fixed to the nut of the bolt assembly 1022 and extends radially along the nut, and is adapted to apply a torque to the nut.

[0110] In this embodiment, to improve assembly and disassembly efficiency while ensuring reliable operation of the bolt assembly 1022 in confined spaces, the connecting device 102 further integrates a wrench 1024 structure. This wrench 1024 is detachably fixed to the nut of the bolt assembly 1022 and extends radially along the nut, forming an operating arm that facilitates the application of force. This design is particularly suitable for applications where the wing sling 100 has a compact structure and limited operating space at its large end.

[0111] In actual clamping, since the second connecting lug 300 and the end plate 1041 are usually located inside the hanging structure or close to the machine body, traditional wrenches 1024 or power tools often cannot directly align with the nut to apply effective force, easily resulting in incomplete tightening or difficulty in disassembly. However, by pre-installing or temporarily mounting the dedicated wrench 1024 on the nut, the operator can apply torque in the radial direction, significantly improving ergonomics, reducing assembly labor intensity, and improving the consistency of preload. In addition, the wrench 1024 adopts a detachable connection method such as a snap-fit, pin, or quick-change interface, which can be removed as needed after tightening, avoiding interference with subsequent rotational movements or drilling paths, thus balancing functionality and space compatibility.

[0112] The radially extended layout of the 1024 wrench not only provides an excellent torque transmission path but also serves as a visual or tactile marker, helping operators quickly identify nut positions and reducing the risk of misoperation. In high-frequency assembly and disassembly production cycles, this integrated tool design effectively shortens auxiliary time and improves overall operational smoothness.

[0113] Example 7:

[0114] Figures 1-13In addition to providing a laser measurement hole-making system, the embodiments of the present invention include the clamping device 1 for 100-division hole-making operations on wing suspension as described in any of the above embodiments, and further include:

[0115] The hole-making device 2 includes a drill bit 22 and a five-axis swivel head assembly 21, the five-axis swivel head assembly 21 being adapted to drive the drill bit 22 to perform a hole-making operation;

[0116] The measuring device 3, supported on the five-axis oscillating head assembly 21, is suitable for measuring the position and direction of the normal line of the surface to be drilled on the wing suspension 100, as well as the depth of the drilled hole;

[0117] The hole-making device 2 can make holes multiple times on the hole position of the surface to be drilled, and the hole depth of the next hole is greater than the hole depth of the previous hole. Before the first hole making at a hole position, the measuring device 3 detects the normal of the surface to be drilled. Before and after the remaining hole making at a hole position, the measuring device 3 detects the normal of the surface to be drilled and the drilling depth.

[0118] In this embodiment, the laser measurement hole-making system is designed specifically for achieving high-precision and high-efficiency hole-making operations on the wing suspension 100 structure. The overall structure integrates the clamping device 1, the hole-making device 2, and the measuring device 3. The three work together to significantly improve the automation level and processing accuracy of the hole-making process.

[0119] The clamping device 1 is used to securely fix the two ends of the wing hanger 100 along its length and has the ability to rotate indexed along the hanger axis, so that continuous hole making operations can be carried out at different circumferential positions of the hanger without re-clamping, effectively reducing clamping errors and improving work efficiency.

[0120] The drilling device 2 includes a drill bit 22 and a five-axis swivel head assembly 21. The five-axis swivel head assembly 21 has multi-degree-of-freedom spatial motion capabilities, which can flexibly adjust the attitude and position of the drill bit 22 to ensure that the drill bit 22 is always perpendicular to the surface to be drilled, thereby achieving precise drilling. The system adopts a layered progressive drilling strategy: at the same hole position, the system performs multiple drilling operations with progressively deeper layers. The drilling depth increases gradually with each operation, thereby effectively reducing the single cutting load, reducing material thermal deformation and tool wear, and improving hole wall quality and dimensional consistency.

[0121] The measuring device 3, integrated into the drive arm using laser sensing technology, can accurately acquire the normal direction of the surface to be drilled before the first hole drilling, providing initial attitude calibration for the five-axis oscillating head assembly 21 and ensuring that the drill bit 22 enters the hole vertically. Before and after each subsequent layer of deepening drilling, the measuring device 3 collects data on the change in the normal direction at the hole position and the current hole depth, forming a closed-loop feedback mechanism. This not only promptly identifies processing deviations caused by material deformation, loose clamping, or equipment drift, but also allows for real-time compensation and adjustment of the subsequent drilling path, ensuring the spatial accuracy and consistency of the final hole position and depth. Furthermore, by performing dual detection before and after each deepening drilling, the system can effectively determine the hole wall quality, preventing the generation of defective holes due to drill bit 22 deviation or material abnormalities. Overall, this technical solution, through the high integration and intelligent collaboration of the clamping, hole drilling, and measurement modules, achieves high-precision, high-reliability automated hole drilling operations on the complex structure of the wing pylon 100, significantly improving the assembly quality and production efficiency of key connection parts in aerospace manufacturing.

[0122] The laser measurement hole-making system also includes a processor, which is connected to the clamping device 1, the hole-making device 2 and the laser measuring device 3, to analyze and record the normal and hole depth information of the measuring device 3, and to control the hole-making device 2 to make holes according to predetermined parameters.

[0123] In this embodiment, the processor, as the core control unit of the system, establishes a real-time communication connection with the clamping device 1, the drilling device 2, and the laser measuring device 3. It can not only receive and store the normal direction and hole depth data of the surface to be drilled acquired during each measurement process, but also perform rapid analysis and processing of this information. Before the first hole drilling, the processor automatically calculates the attitude parameters that the five-axis swivel head assembly 21 needs to adjust based on the normal information fed back by the laser measuring device 3, ensuring that the initial entry direction of the drill bit 22 is strictly aligned with the surface normal. During subsequent layer-by-layer drilling, the processor continuously compares the changes in normal and hole depth measured before and after each drilling, dynamically judging whether the current processing state deviates from the preset trajectory or has abnormal deformation, and accordingly corrects the motion commands of the five-axis swivel head 212 in real time, achieving adaptive compensation control.

[0124] All measurement data and machining parameters are recorded and archived, facilitating subsequent quality traceability and process optimization. Simultaneously, reduced manual intervention and trial-and-error adjustments improve overall hole-making efficiency, extend tool life, and lower scrap rates, providing solid technical support for the stable mass production of high-reliability connecting holes in aerospace manufacturing.

[0125] The five-axis oscillating head assembly 21 includes a robotic arm 211 and an oscillating head 212. The oscillating head 212 is oscillatingly connected to the front end of the robotic arm 211. The oscillating head 212 has a rotation drive end, and the drill bit 22 is fixedly connected to the rotation drive end. A mounting surface is formed on one side wall of the oscillating head 212 corresponding to the oscillation direction. The measuring device 3 is fixedly connected to the mounting surface so that the measuring device 3 can oscillate synchronously with the oscillating head 212.

[0126] In this embodiment, the oscillating head 212 is oscillatingly connected to the front end of the robotic arm 211 via a high-precision hinge structure, enabling it to rotate flexibly around a specific axis. The drill bit 22 is rigidly fixed to the rotation drive end of the oscillating head 212 and is directly driven to rotate by a built-in drive mechanism, achieving efficient cutting. The laser measuring device 3 is firmly mounted on the mounting surface, forming a rigidly connected integral structure with the oscillating head 212. This arrangement ensures that the measuring device 3 can synchronously adjust its spatial attitude with the oscillating head 212. Regardless of how the oscillating head 212 rotates or tilts, the optical axis of the measuring device 3 always maintains a fixed geometric relationship with the machining axis of the drill bit 22. Since the measuring device 3 and the drill bit 22 share the same motion platform, the normal and hole depth data it collects can be directly mapped to the current coordinate system of the drill bit 22, greatly simplifying the data processing logic and improving the real-time performance and accuracy of feedback control.

[0127] The robotic arm 211 is provided with a clearance opening 20, which can make way for the measuring device 3 when the swing head 212 swings.

[0128] In this embodiment, the position and contour of the clearance opening 20 are precisely calculated and optimized to ensure that when the swing head 212 swings at a large angle around its hinge axis, the measuring device 3 fixed to the mounting surface of the side wall of the swing head 212 can smoothly pass through the space occupied by the robotic arm 211 without structural collision or movement obstruction. This not only ensures the free movement capability of the swing head 212 within the entire working envelope, but also avoids damage to the measuring device 3 or attitude deviation caused by mechanical interference, thereby maintaining the stability and safety of the system's long-term operation.

[0129] Since there is no need to limit the range of motion of the oscillating head 212 to avoid the measuring device 3, the five-axis oscillating head assembly 21 can give full play to its multi-degree-of-freedom advantage. Even when facing highly complex curved surfaces or narrow spaces on the wing sling 100, it can still flexibly adjust to the ideal machining posture, effectively supporting the continuous and stable execution of high-precision and highly adaptable hole-making operations.

[0130] The measuring device 3 includes a telescopic drive 31 and a laser measuring module 32 fixedly connected to the telescopic end of the telescopic drive 31. The fixed end of the telescopic drive 31 is fixedly connected to the mounting surface. The telescopic direction of the telescopic end of the telescopic drive 31 is parallel to the axial direction of the drill bit 22. The laser measuring module 32 is suitable for measuring the normal of the surface to be drilled and the drilling depth.

[0131] In this embodiment, the measuring device 3 in the system adopts a modular and scalable structural design. The fixed end of the telescopic drive 31 is firmly installed on the mounting surface of the side wall of the swing head 212, and its telescopic end moves linearly in a direction strictly parallel to the axis of the drill bit 22. The laser measuring module 32 is rigidly connected to the end of the telescopic end, ensuring that the laser measuring module 32 can accurately approach or move away from the surface to be drilled along the feed direction of the drill bit 22 when working, so as to realize non-contact high-precision measurement of the target area.

[0132] In the actual hole-making process, after the oscillating head 212 is adjusted to the target hole position, the telescopic drive 31 first drives the laser measurement module 32 to extend to the preset measurement distance, identifying the normal direction of the surface to be processed. After the initial hole-making is completed, during subsequent layer-by-layer deepening processes, the telescopic drive 31 drives the laser measurement module 32 to extend again, performing a combined measurement of the normal and hole depth of the current hole bottom and surrounding area after the drill bit 22 exits the hole position. Because the telescopic direction is parallel to the axis of the drill bit 22, the optical axis of the laser measurement module 32 can always be perpendicular to the theoretical hole bottom plane, greatly improving the accuracy of depth measurement and avoiding deviations in normal calculation caused by oblique projection. In addition, during non-measurement phases, the telescopic drive 31 can retract the laser measurement module 32 to a safe position, effectively preventing damage from drill cuttings splashing, coolant corrosion, or accidental collisions, significantly improving the durability and ease of maintenance of the device.

[0133] The drive end of the telescopic drive 31 can extend to bring the measuring device 3 closer to the surface to be drilled, so that the measuring device 3 enters the measuring state, or it can shorten to move the measuring device 3 further away from the surface to be drilled, so that the measuring device 3 enters the drilling clearance state.

[0134] The telescopic drive component 31 can dynamically adjust the extension amount of the laser measurement module 32 according to the actual space conditions, ensuring that it is always within the optimal measurement working distance. Combined with the processor's real-time analysis and feedback of the measurement data, it provides a reliable guarantee for the high-quality and high-consistency manufacturing of key connection holes on high-value aerospace components such as the wing pylon 100.

[0135] Specifically, when entering the measurement state, the drive end extends, precisely moving the laser measurement module 32 forward along the axis of the drill bit 22, bringing it close to the surface to be drilled to the preset optimal measurement distance. This ensures that the laser beam can stably and clearly capture surface topography information and accurately obtain normal direction and hole depth data. When entering the drilling clearance state, the drive end quickly retracts, pulling the laser measurement module 32 away from the processing area to a safe position outside the movement path of the drill bit 22. This effectively avoids interference or collision between the laser measurement module and the drill bit 22 during high-speed rotation, feeding, or retraction. This not only ensures the physical safety of the laser measurement module 32 in harsh processing environments but also significantly improves the continuity and reliability of the system operation. Since the measurement device 32 only extends when necessary and remains in a retracted protective state at other times, the risk of sensor contamination or performance drift caused by chip accumulation, coolant splashing, or vibration impact can be greatly reduced. Meanwhile, the telescopic movement is uniformly scheduled by the processor and is strictly synchronized with the start and stop of the hole-making device 2, the attitude adjustment of the swing head 212, and the indexing rotation of the clamping device 1, forming a smooth and conflict-free automated operation rhythm, which improves the hole-making efficiency.

[0136] Furthermore, a heating module can be installed near the lens of the laser measurement module 32 to heat the lens in real time to remove splashed cutting fluid. Simultaneously, the heating module can work in conjunction with the air outlet and cleaning fluid outlet facing upwards towards the lens to further clean the lens, thereby improving the cleanliness of the lens and enhancing the detection accuracy of the laser measurement module 32.

[0137] Furthermore, a rotary cable chain can be installed on one side of the robotic arm 211, and the relevant wiring harnesses and conduits can be adapted to the swing of the swing head 212 through the rotary cable chain.

[0138] The drill bit 22 includes a front drilling section 221 and a rear countersinking section 222, which are coaxial, so that the hole-making device 2 can countersink during drilling.

[0139] In this embodiment, the drilling part 221 is responsible for forming through holes or blind holes in the processing area of ​​the wing hanger 100, while the countersinking part 222 that follows behind countersinks the material around the hole on the same axis to form a groove required for the installation of countersunk screws or rivets. This eliminates the need to change tools or perform secondary positioning of the countersinking in the traditional process, significantly shortens the single hole processing cycle, and avoids the cumulative error caused by multiple clamping or tool setting.

[0140] The laser measurement hole-making system has two adjacent workstations; the system also includes a two-axis truss 4, on which the hole-making device 2 is supported, so that the hole-making device 2 can switch between the two workstations; the clamping device 1 is set in two sets and is correspondingly installed on the two workstations, so that one workstation becomes a processing workstation and the other workstation becomes a waiting workstation.

[0141] In this embodiment, each workstation is equipped with an independent clamping device 1 for clamping 100 workpieces suspended from the wing. One set of workstations serves as the processing workstation, performing actual measurement, drilling, and countersinking operations, while the other set serves as a waiting workstation for pre-clamping the next workpiece to be processed or unloading completed workpieces. The drilling device 2 is supported by a two-axis truss 4 covering the two workstations and can move freely in the X and Y axes, allowing for a quick and smooth transition to another workstation after completing the processing task at the current workstation.

[0142] The dual-station alternating operation mode enables parallel "processing-loading" operations: when the drilling device 2 is performing high-precision drilling on the current hanger at the processing station, operators or automated loading and unloading equipment can simultaneously perform workpiece replacement, clamping calibration, or quality inspection at the waiting station without stopping the machine. After the processing station completes its work, the two-axis gantry 4 drives the drilling device 2 to move to the waiting station, which then becomes the processing station, while the original processing station returns to a waiting state, forming an efficient cycle. This not only significantly shortens non-processing time and improves equipment utilization but also effectively alleviates the cycle time bottleneck caused by high-precision requirements in aerospace manufacturing.

[0143] Furthermore, since the two clamping devices 1 have the same structure and fixed position, the system can establish a unified global coordinate system through calibration, ensuring that the hole-making device 2 does not need to recalibrate the reference when switching between the two stations, which further improves the hole-making efficiency.

[0144] A safety partition, constructed of high-strength, impact-resistant protective material, physically separates the machining station from the waiting station, effectively preventing the transmission of flying chips, coolant splashes, drill bit fragments, or accidental vibrations that may occur during machining. Especially in machining high-value, high-precision components such as wing-mounted parts, this isolation measure not only protects workpieces already clamped or awaiting clamping at the waiting station from contamination or damage but also significantly reduces the risk of operators being exposed to hazardous areas during workpiece loading and unloading.

[0145] Furthermore, the introduction of the safety partition optimizes the system's working environment zoning. High-speed drilling and countersinking at the machining station often involve significant noise and localized airflow disturbances. The safety partition acts as an acoustic and airflow barrier, providing a relatively clean and stable auxiliary operating space for waiting stations. This facilitates manual or automated equipment for precision clamping, visual inspection, or auxiliary measurements. Simultaneously, the partition can integrate a light curtain sensor. When the drilling device 2 is operating at the machining station, if it detects personnel or foreign objects intruding into the machining station area, the system can automatically pause operation, further enhancing safety.

[0146] This invention provides a laser measurement method for hole fabrication, the method comprising:

[0147] S1: Mount the wing sling 100 onto the mounting device 1;

[0148] S2: Control the clamping device 1 to rotate the wing hanger 100 to the predetermined machining angle and fix it;

[0149] S3: Measure the normal of the hole position on the surface to be machined corresponding to the predetermined machining angle using measuring device 3;

[0150] S4: Based on the normal, control the hole-making device 2 to make a hole at the hole position to a predetermined depth;

[0151] S5: The normal and depth of the hole are measured by the measuring device 3, and the hole-making device 2 corrects the normal and depth of the next hole-making operation based on the normal and depth.

[0152] S6: Control the hole-making device 2 to make a hole at the predetermined position to form a final through hole, the depth of the final through hole is greater than the depth of the previous hole;

[0153] S7: Determine whether the normal and depth of the final through hole meet the predetermined requirements;

[0154] Based on the fact that the normal and depth of the final through hole meet the predetermined requirements, execute S8:

[0155] S8: Determine whether the drilling operation of all through holes under the predetermined machining angle has been completed;

[0156] S8.1: Repeat S3-S8 for hole making operations based on the fact that not all through holes under the given machining angle have been completed;

[0157] S8.2: Based on the completion of hole-making operations for all through holes at a predetermined machining angle, execute S9:

[0158] S9: Determine whether the hole-making operation under all indexing angles has been completed;

[0159] S9.1: Based on the hole-making operation under incomplete indexing angle, repeat S2-S9;

[0160] S9.2: End based on the completion of hole-making operations at all indexing angles.

[0161] In this embodiment, the laser measurement and drilling method relies on the aforementioned highly integrated laser measurement and drilling system. Through multi-level closed-loop control and layered progressive processing strategies, it achieves automated and intelligent drilling of high-precision through holes on the complex curved surface of the wing hanger. This ensures that each hole strictly meets the stringent requirements of aerospace assembly in terms of spatial attitude and geometric dimensions.

[0162] The method first securely clamps the wing suspender 100 to the clamping device 1 in step S1, and uses the differentiated connection structure at both ends and the corresponding connection components to achieve high rigidity and repeatable positioning clamping, laying the foundation for reference stability for subsequent processing.

[0163] Subsequently, in S2, the system controls two turntables to precisely rotate the hanger to the preset indexing angle and lock it, ensuring that the current area to be processed is in the optimal working posture of the hole-making device 2.

[0164] S3 uses a laser measuring device 3 mounted on the swivel head 212 to perform a non-contact scan of the surface to be machined at the current hole position, obtaining its local normal direction. This normal data is transmitted to the processor in real time, which is used in S4 to drive the five-axis swivel head assembly 21 to dynamically adjust the attitude of the drill bit 22, ensuring that its axis is strictly aligned with the surface normal, and to perform the first hole drilling to the preset intermediate depth. This stage employs a layered drilling strategy to avoid the risks of tool runout, material tearing, or thermal deformation caused by single deep hole machining.

[0165] Subsequently, in S5, the measuring device 3 extends again to perform dual detection of the normal and hole depth of the previously machined hole. Because the material may experience slight elastic recovery or local deformation during drilling, the actual hole axis may deviate from the theoretical normal, and the hole depth may also deviate due to feed fluctuations. Based on this measurement result, the processor dynamically compensates for the path of the next drilling deepening in S6, not only correcting the entry angle of the drill bit 22 but also fine-tuning the target depth to ensure that the axial direction of the final through hole is consistent with the designed normal height, and the hole depth accurately meets the target.

[0166] S7, as a quality gate, judges the normal deviation and depth error of the final through hole. The system only accepts the hole as qualified if both are within the allowable tolerance range; otherwise, an alarm is triggered or a supplementary machining process is started. If the current hole position is qualified, S8 is entered to determine if there are other holes to be machined at the current indexing angle; if so, S3 to S8 are executed in a loop to achieve closed-loop machining of multiple holes at the same angle.

[0167] Once all holes at a certain angle are completed and verified to be qualified, the system enters S9 to determine whether the hole-making task for all indexing angles has been completed. If not, it returns to S2, drives the turntable to switch to the next processing angle, and repeats the entire hole-making cycle; if yes, it indicates that all specified holes for the entire part have been completed with high precision, and the process ends.

[0168] The beneficial effects of this method are as follows: it transforms traditional open-loop hole making into adaptive intelligent machining, significantly improving the consistency of hole position, perpendicularity, and depth; layered drilling combined with real-time feedback effectively suppresses deformation of thin-walled structures and tool wear; the dual-station and rotary table indexing design ensures continuous and efficient operation at multiple angles and hole positions; and the full-process data recording and judgment logic provides a digital foundation for quality traceability and process optimization. Overall, this method not only meets the precision requirements of high-reliability connection holes in aerospace manufacturing but also significantly improves the automation level and production efficiency of hole making for complex structural components.

[0169] Furthermore, a single hole can be drilled twice: first for roughing, and second for finishing. Specifically, this drilling method requires three laser scans to measure the hole position, taking approximately 15 seconds. The three data processing steps after each scan take about 20 seconds. The first roughing operation takes about 25 seconds, and the second finishing operation takes about 15 seconds, for a total drilling time of approximately 75 seconds per hole. In a single indexing operation, drilling 600 holes can be completed in under 750 minutes, significantly improving drilling efficiency, shortening drilling time, and ensuring drilling accuracy.

[0170] For a single wing pylon 100, the entire drilling operation is typically completed with only one indexing rotation. During the first indexing, drilling operations on the front, rear, and top surfaces can be completed using the five-axis oscillating head 212. During the second indexing, the bottom surface corresponding to the first indexing needs to be rotated to a position suitable for drilling, so that the drilling operation can be completed using the five-axis oscillating head 212.

[0171] Specifically, when correcting the drilling parameters, the system controls the state of the five-axis oscillating head assembly 21 and its position on the two-axis truss based on the parameters measured by the measuring device 3. Then, according to the calculated correct drilling parameters, the drilling angle, depth, position and direction are corrected so that the hole produced meets the requirements.
