Description

Technical Field

[0001] This utility model relates to the technical field of wing joint positioning tools, and in particular to a modular adjustable wing joint positioning inspection device. Background Technology

[0002] In the field of aircraft manufacturing and assembly, the precise docking of key components such as wings, ailerons, and flaps is a core element in ensuring the overall aerodynamic performance and flight safety of an aircraft. The connection of these components relies on high-precision joints, the position of which is considered a critical characteristic. To ensure the positioning accuracy of the joints during assembly, specialized assembly jigs and fixtures are commonly used for fixing and calibration in production. The accuracy of the jigs and fixtures themselves directly determines the final docking quality of the components.

[0003] Currently, the inspection of the position of assembly jigs and wing joints mainly relies on high-precision measuring equipment such as laser trackers. While this technology offers high accuracy, it has significant limitations in practical applications: the high cost of equipment purchase and maintenance limits the number of units available to companies; coordination in actual production environments is difficult; and the testing process is complex and time-consuming, failing to meet the demands for rapid and frequent calibration of jigs in multi-model, fast-paced production environments. Therefore, there is an urgent need for a more cost-effective, easier-to-operate, and universally applicable method for rapid on-site inspection of assembly jigs and wing joints.

[0004] To address the aforementioned problems, this utility model aims to provide an inspection device for wing joint positioning that can quickly and intuitively verify the position of assembly jigs or assembled joints. This significantly reduces equipment dependence and operational complexity while ensuring the uniqueness and accuracy of the inspection benchmark, improves the efficiency of troubleshooting and quality control, and enhances the tool's versatility and practicality. Summary of the Invention

[0005] In view of the problems existing in the above-mentioned wing joint positioning and inspection device, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution, including: a base plate; a positioning module, which is disposed on the base plate and can move along its length; and a replaceable inspection head is installed on the positioning module.

[0008] A positioning hole is provided on the top of the replaceable inspection head.

[0022] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0024] Example 1, referring to Figure 1 The first embodiment of this utility model provides a wing joint positioning inspection device, which includes a base plate 1; a positioning module disposed on the base plate 1 and movable along its length; and a replaceable inspection head 2 installed on the positioning module.

[0025] Positioning hole 3 is provided on the top of the replaceable inspection head 2.

[0026] The system includes a positioning module mounted on the upper surface of the base plate 1. This module can move linearly along the length of the base plate 1 via mechanical means (e.g., guide rails, slides). A replaceable inspection head 2 is mounted on top of the positioning module, typically connected detachably by bolts, quick-connect fittings, or positioning pins. A positioning hole 3 is precisely machined into the top of the replaceable inspection head 2. In use, the entire positioning module is moved to approximate coordinates on the base plate 1 based on the theoretical hole position on the wing joint to be inspected. Then, an inspection pin or measuring tool is inserted into the positioning hole 3 on the top of the inspection head to compare its position with the actual hole on the wing joint, thus verifying its positional accuracy. By replacing the replaceable inspection head 2 with different top structures or positioning hole 3 sizes, it can quickly adapt to the inspection tasks of wing joints of different aircraft models or specifications. This achieves the core function of adapting to different inspection needs by moving and replacing components, freeing it from the constraints of traditional fixed inspection fixtures.

[0027] Furthermore, the positioning module includes a linear guide rail 4 mounted on the base plate 1, and a slider 5 that slides with the linear guide rail 4; a replaceable inspection head 2 is mounted on the slider 5.

[0028] One specific implementation of the positioning module involves fixing one or more high-precision linear guides 4 onto the base plate 1. One or more sliders 5 slide smoothly along the linear guides 4. The replaceable inspection head 2 is directly fixedly mounted on the top surface of the slider 5. Operators can manually or with tools push the slider 5, causing the inspection head to move precisely in a straight line along the linear guides 4 without worrying about path deviation. The linear guides 4 provide high rigidity and low friction for movement guidance, ensuring the linear accuracy and stability of the inspection head's trajectory, laying a solid mechanical foundation for high-precision positioning.

[0029] Furthermore, a scale 6 is provided on the base plate 1, and the extension direction of the scale 6 is parallel to the extension direction of the linear guide rail 4.

[0030] On the upper surface of the base plate 1, adjacent to the linear guide rail 4, a clear scale 6 is set by inlay or engraving. The scale 6 has an accuracy of 0.1mm. The length direction of the scale 6 is strictly parallel to the extension direction of the linear guide rail 4, and its zero mark corresponds to a reference position. When moving the slider 5, the operator can observe the reading of the scale 6 aligned with the pointer or mark line on the slider 5, directly and intuitively reading the approximate position coordinates of the inspection head, achieving rapid coarse positioning. Optionally, a fine-tuning bolt is set on the slider 5. The core objective is to achieve precise adjustment of the slider at the 0.001-0.01mm level through the small displacement characteristics of the threaded transmission, compensating for the insufficient accuracy of the coarse adjustment of the scale. Based on the visualized position feedback, rapid adjustment and preliminary positioning are greatly facilitated, reducing the time spent on repeated measurement and comparison, and improving adjustment efficiency.

[0031] Furthermore, the bottom of the base plate 1 is connected to a leveling foot 7.

[0032] A leveling foot 7 is installed at each of the four corners or key support points of the bottom of the base plate 1. This leveling foot typically consists of a threaded support and a lock nut, and its extension length can be changed by rotation. After placing the device on the work platform, a level is placed on the reference surface of the base plate 1. Then, each leveling foot 7 is rotated until the base plate 1 is level, and finally, the lock nut is tightened. This ensures that the mounting reference surface of the entire inspection device is level, eliminating systematic errors caused by uneven platform surfaces, guaranteeing that all positioning and measurements are performed under standard spatial relationships, and improving the accuracy of the inspection results.

[0033] Furthermore, a replaceable sleeve 31 is fitted inside the positioning hole 3.

[0034] A replaceable sleeve 31 is fitted with an interference or clearance fit in the positioning hole 3 at the top of the replaceable inspection head 2. This sleeve is typically made of wear-resistant alloy steel, with a high-precision through-hole inner bore. Inspection pins or standard mandrels are inserted into the inner bore of the replaceable sleeve 31 for operation. When the inner bore of the sleeve wears down due to long-term use or when it needs to be fitted with inspection pins of different diameters, it can be pressed out with a special tool to replace the sleeve, eliminating the need to replace the entire expensive inspection head. Designing the most easily worn positioning part as a replaceable component greatly extends the service life of the inspection head body and reduces maintenance costs. Furthermore, by replacing sleeves with different inner diameters, various specifications of inspection tools can be flexibly matched.

[0035] In practical use, the device is placed on a stable platform via the leveling feet 7 at the bottom of the base plate 1, and adjusted to a horizontal state using a level. The leveling feet are then locked to establish a precise measurement reference plane. Using the replaceable inspection head 2 mounted on the slider 5, the slider 5 is manually pushed along the linear guide rail 4 to move the replaceable inspection head 2 to the theoretical coordinates. The standard inspection pin (or mandrel) is inserted into the replaceable sleeve 31 inside the positioning hole 3 of the inspection head, attempting to pass it through the corresponding actual hole on the wing joint. If it passes through smoothly, the hole position is qualified; if not, the direction and magnitude of the deviation can be determined based on the deviation. For inspection requirements of different diameters, replaceable sleeves 31 with different inner diameters or the entire replaceable inspection head 2.

[0036] Example 2, refer to Figure 1 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the slider 5 is connected to a locking mechanism 51 for locking it to the linear guide rail 4.

[0037] Optionally, a locking mechanism 51 can be installed on one side of the slider 5, or one locking mechanism 51 can be installed on each of the two sides of the slider 5. By operating this mechanism, the pressure block can be driven to generate a clamping force to prevent the slider 5 from moving. When the slider 5 moves to near the target position, the locking mechanism 51 can securely lock the slider 5 onto the linear guide 4 within seconds, preventing it from moving accidentally during the inspection process. This achieves rapid fixing and releasing of the inspection head position. Compared with the traditional bolt tightening method, the operation speed is extremely fast, significantly improving work efficiency and ensuring structural stability during the inspection process.

[0038] Furthermore, the locking mechanism 51 includes a handle 511, a connecting rod 512, and a pair of clamping blocks 513. The connecting rod 512 is disposed inside the slider 5, and its middle part is connected to the end of the handle 511; the handle 511 passes through the first side of the slider 5 and is connected to the connecting rod 512. The two ends of the connecting rod 512 are respectively connected to a clamping block 513.

[0039] The handle 511 passes through a mounting hole on the side of the slider 5, and its end is connected to the middle of the connecting rod 512 via a keyway or thread. The connecting rod 512 is horizontally arranged, and its two ends are connected to a pair of symmetrically arranged clamping blocks 513 via pins. When the handle 511 is pressed or pulled, it moves the connecting rod 512 closer to or away from the linear guide rail 4, changing the position of the connecting rod 512, and thus driving the clamping blocks 513 at both ends to move synchronously closer to or away from the linear guide rail 4 along the grooves on both sides of the slider 5.

[0040] Furthermore, clamping blocks 513 are disposed in the grooves on both sides of the slider 5. By pressing the handle 511, the connecting rod 512 can be driven to move, thereby driving a pair of clamping blocks 513 to move closer to the slider 5. When the clamping blocks 513 press against the linear guide rail 4, the slider 5 is locked on the linear guide rail 4. Pulling the handle 511 in the opposite direction can cause the clamping blocks 513 to retract into the slider 5, releasing the lock on the slider 5.

[0041] In this design, each arm of the U-shaped connecting rod 512 is connected to a clamping block 513, and its middle section is connected to the drive end of the handle 511 via a hinge shaft. When the handle 511 is pressed, the U-shaped connecting rod 512 is displaced, causing the clamping blocks 513 at both ends to move closer to the linear guide rail 4 along the grooves of the slider 5. When it is necessary to clamp the slider 5, the operator presses the handle 511, causing the U-shaped connecting rod 512 to displace, causing the clamping blocks 513 at both ends to move closer to the linear guide rail 4 along the grooves of the slider 5. The clamping blocks 513 press tightly against the side or groove of the linear guide rail 4, generating friction to clamp the slider 5 and prevent it from moving. When the slider 5 needs to move, the handle 511 is pulled away from the slider 5, causing the clamping blocks 513 to disengage from the linear guide rail 4 and retract into the grooves on both sides of the slider 5. The connecting rod 512 then displaces, allowing the slider 5 to slide freely. This structure has the advantages of simple transmission, uniform locking force, and quick operation.

[0042] The remaining structure is the same as that in Example 1.

[0043] During use, place the device on a stable platform using the leveling feet 7 at the bottom of the base plate 1, and adjust it to a horizontal state using a level. Lock the leveling feet to establish a precise measurement reference plane. Using the replaceable inspection head 2 mounted on the slider 5, pull the handle 511 away from the slider 5. The clamping blocks 513 disengage from the linear guide rail 4 and retract into the grooves on both sides of the slider 5. The connecting rod 512 shifts, allowing the slider 5 to slide freely. Manually push the slider 5 along the linear guide rail 4 to move the replaceable inspection head 2 to the theoretical coordinates. The operator presses the handle 511, causing the U-shaped connecting rod 512 to shift, thus bringing the clamping blocks 513 at both ends closer to the linear guide rail 4 along the grooves of the slider 5. The clamping blocks 513 press tightly against the side or groove of the linear guide rail 4, generating friction to clamp the slider 5 and securely lock it. Insert the standard inspection pin (or mandrel) into the replaceable sleeve 31 in the positioning hole 3 of the inspection head and try to pass it through the corresponding actual hole on the wing joint. If the hole can pass through smoothly, it indicates that the hole position is qualified; if it cannot, the direction and magnitude of the deviation can be determined based on the deviation. For inspection requirements of different diameters, a replaceable sleeve 31 with a different inner diameter or the entire replaceable inspection head 2 can be used.

[0044] Example 3, referring to Figure 1 This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that it also includes a multi-inspection head mounting base, which is detachably connected to the base plate 1; and multiple replaceable inspection heads 2 are connected side by side on the multi-inspection head mounting base.

[0045] Furthermore, the multi-inspection head mounting base is rotatably connected to the base plate 1 via a rotating shaft 9.

[0046] In actual workpieces such as aircraft wing joints, the center line of a hole system consisting of multiple positioning holes 3 is often not parallel to the reference edge of the device base plate 1, but rather at a certain spatial angle (e.g., an oblique row of holes at a certain angle to the aircraft fuselage axis). If the inspection device cannot make fine-tuning adjustments, the operator must move or twist the entire heavy base plate 1 to align the hole system, which will disrupt the precise horizontal reference established by the leveling feet 7, leading to inaccurate measurements and cumbersome operation. This device perfectly solves this problem through the independent rotation design of the multi-inspection head mounting base. The operator first uses the leveling feet 7 to precisely adjust and lock the base plate 1 in a horizontal state, establishing a stable and unchanging measurement reference plane. When encountering an oblique hole system, the replaceable inspection heads 2 are installed in the corresponding positions according to the multiple positioning holes 3. After fine-tuning each replaceable inspection head 2, simply loosen the rotating shaft 9 and then gently rotate the multi-inspection head mounting base so that the direction of the line connecting the row of inspection heads on the mounting base is parallel to the axial direction of the hole system to be inspected on the workpiece. Precise readings can be obtained through the angle dial. After the angle is adjusted to the correct position, lock the rotating shaft 9. At this point, the axes of the positioning holes 3 of all inspection heads are aligned with the axes of the workpiece holes, while the horizontal reference of the base plate 1 remains unchanged. Multiple inspection pins can then be inserted for simultaneous inspection. This achieves rapid and accurate adaptation to multi-hole inspection needs at different spatial angles without disturbing the overall measurement reference, greatly enhancing the device's versatility, ease of operation, and measurement reliability.

[0047] The remaining structure is the same as that in Example 2.

[0048] In practical use, the device is placed on a stable platform via the leveling feet 7 at the bottom of the base plate 1, and adjusted to a horizontal state using a level. The leveling feet are then locked to establish a precise measurement reference plane. Appropriate inspection components are selected based on the model, number of holes (single or multiple holes), and layout of the wing joint to be inspected. Firstly, for single holes or holes requiring independent inspection, the replaceable inspection head 2 mounted on the slider 5 is used. The handle 511 is pulled away from the slider 5, causing the clamping block 513 to disengage from the linear guide rail 4. The clamping block 513 retracts into the grooves on both sides of the slider 5, causing the connecting rod 512 to shift. The slider 5 can then slide freely. The slider 5 is manually pushed along the linear guide rail 4 to move the replaceable inspection head 2 to the theoretical coordinates. The operator presses handle 511, causing the U-shaped connecting rod 512 to shift, thus bringing the clamping blocks 513 at both ends closer to the linear guide rail 4 along the groove of the slider 5. The clamping blocks 513 press tightly against the side or groove of the linear guide rail 4, generating friction to clamp the slider 5 and securely lock it. A standard inspection pin (or mandrel) is inserted into the replaceable sleeve 31 in the inspection head positioning hole 3, attempting to pass it through the corresponding actual hole on the wing joint. If it passes smoothly, the hole position is acceptable; if not, the direction and magnitude of the deviation can be determined based on the deviation. For inspection requirements of different diameters, replaceable sleeves 31 with different inner diameters or the entire replaceable inspection head 2. Secondly, for joints with multiple parallel holes, install a multi-inspection head mounting base on the base plate 1, and install the corresponding number and spacing of replaceable inspection heads 2 on the mounting base according to the theoretical spacing of the joint holes. If it is necessary to inspect angled hole systems, loosen the rotating shaft 9, adjust the mounting base to the required angle, and then lock it. Install and configure multiple inspection head mounting bases and their associated inspection heads. Move the entire assembly under the connector, ensuring that the positioning holes 3 of all inspection heads are roughly aligned with the corresponding theoretical holes on the connector. Insert the inspection pins sequentially into the positioning holes 3 of each inspection head, attempting to pass them through all corresponding holes on the connector simultaneously or sequentially. If all inspection pins pass through smoothly and without interference, the relative positional accuracy between the multiple holes is deemed acceptable. This method eliminates the need for individual movement and locking of each hole, achieving simultaneous positioning and inspection, significantly improving the inspection efficiency and consistency of multi-hole connector products.

[0049] The adjustable wing joint positioning inspection device provided by this utility model brings significant progress and benefits in multiple dimensions such as technology, efficiency, economy, and applicability. Technically, the device integrates a high-precision linear guide rail 4, a slider 5 with a locking mechanism 51, and a scale 6 to construct a stable and quantifiable adjustable positioning benchmark. This enables rapid coarse adjustment and reliable locking of the inspection head position, overcoming the problems of traditional methods relying on intuition or repeated measurements, fundamentally ensuring the consistency of positioning and the repeatability of inspection. In terms of efficiency improvement, the modular, replaceable inspection head 2 and multi-inspection head mounting design allow for the pre-configuration of multiple inspection units and can quickly adapt to non-parallel hole systems via the rotating shaft 9. This achieves "one-stop" rapid inspection from single-hole to multi-hole and from parallel to angled hole systems, greatly shortening the cycle of tooling calibration or product inspection. In terms of economy and practicality, this device replaces expensive and complex large-scale measuring equipment such as laser trackers with a mechanical structure, significantly reducing purchase and maintenance costs. Its simple and robust structure makes it ideal for frequent use by frontline operators on the production floor, lowering the technical threshold and reducing reliance on professional measuring personnel. Finally, its excellent applicability and scalability are reflected in its ability to flexibly adapt to different aircraft models and connector diameters by changing different specifications of inspection heads or sleeves; and its ability to meet inspection needs in various spatial attitudes by adjusting the horizontal and rotation angles, truly achieving multi-purpose functionality and effectively solving the pain point of poor tooling and inspection fixture versatility in multi-variety, small-batch production in the aerospace manufacturing field. In summary, this device successfully combines low cost, high efficiency, strong versatility, and ease of operation while ensuring high-precision inspection, providing an efficient and reliable on-site solution for quality control of key components such as wing connectors.
