Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a zero-position fixture for a slatted wing. Background Technology

[0002] Aircraft slats require repeated disassembly, assembly, testing, and adjustment of their installation position. Each disassembly or adjustment will disrupt the slat's zero position, necessitating a re-determination of the slat's zero position to match the control system program, thereby enabling the control system to accurately control the slat's movement and obtain correct feedback.

[0003] However, in the existing technology, due to the narrow space and complex structure of the slat, its zero position cannot be directly measured. It is necessary to use a feeler gauge to measure the gap between the existing tooling and the aircraft structure to determine whether the slat is in the zero position. This not only fails to achieve convenient positioning of the slat's zero position, but also cannot guarantee the consistency of the slat's zero position due to the narrow structure of the slat.

[0004] Therefore, there is an urgent need for a slat zero-position fixture to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this invention is to provide a slat zero-position fixture that, while enabling convenient positioning of the slat zero-position, also ensures the consistency of the slat zero-position positioning.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A slat zero-position fixture is provided for positioning the zero position of a slat, wherein the slat is slidably connected to a slide rail, and the slat zero-position fixture includes:

[0008] The base is fixedly connected to the slide rail, and the base has a first reference platform for supporting the slats;

[0009] The positioning component includes a connecting arm and a second reference platform. The connecting arm is slidably connected to the base and the connecting arm is connected to the second reference platform. The connecting arm can slide to allow the second reference platform to switch between a positioning position abutting the slat and a free position away from the slat. The connecting arm is also marked with a scale arranged along its own sliding direction, which can read the scale corresponding to the positioning position of the second reference platform.

[0010] Preferably, the slide rail has a first connecting hole and the base has a second connecting hole, and the base is detachably connected to the slide rail by a locking assembly.

[0011] Preferably, the locking assembly includes a fastener and a nut, the positioning rod of the fastener passes through the first connecting hole and the second connecting hole, the positioning rod is an optical shaft with external threads, and the nut is threadedly connected to the positioning rod, thereby fixing the base to the slide rail.

[0012] Preferably, a bushing is also installed in the second connecting hole, and the positioning rod is clearance-fitted with the bushing.

[0013] Preferably, the base is further provided with a through hole, and the connecting arm is engaged with the through hole shaft.

[0014] Preferably, the second reference platform has an abutting surface for abutting the slat, and when the second reference platform is in the free position, the vertical distance H1 between the abutting surface and the slat is less than the length H2 of the connecting arm extending out of the through hole.

[0015] Preferably, the base also has a first support surface, which supports the second reference platform when the second reference platform is in a free position.

[0016] Preferably, the base is further provided with a receiving groove, and the bottom wall of the receiving groove is the first support surface.

[0017] Preferably, the slat has two rolling bearings, which are coaxially arranged. The first reference platform is used to support the outer ring surface of one of the rolling bearings, and the second reference platform is used to abut against the outer ring surface of the other rolling bearing.

[0018] Preferably, the first reference platform has a second support surface for supporting the rolling bearing, the width D1 of the second support surface being no greater than the outer ring wall thickness of the rolling bearing; and / or the second reference platform has an abutment surface for supporting the rolling bearing, the width D2 of the abutment surface being no greater than the outer ring wall thickness of the rolling bearing.

[0019] The beneficial effects of this utility model are:

[0020] The slat zero-position fixture provided by this utility model obtains a first measurement reference by fixing the base to the slide rail and having the first reference platform support the slat. By marking the scale on the connecting arm arranged along its sliding direction, after the connecting arm slides and the second reference platform switches from a free position away from the slat to a positioning position abutting the slat, the scale corresponding to the second reference platform at the positioning position can be read, thereby locating the zero position of the slat. When the slat is disassembled, installed, or tested and adjusted, after obtaining the first measurement reference, the connecting arm can be slid again to switch the second reference platform from a free position away from the slat to a positioning position abutting the slat, and the scale corresponding to the second reference platform at the positioning position can be read again. The installation position of the slat can be adjusted so that the scale corresponding to the second reference platform when it is in the positioning position for the second time is the same as the scale corresponding to the second reference platform when it is in the positioning position for the first time, so that the zero position of the slat is the same in the two instances. Thus, while achieving convenient positioning of the slat zero position, the sameness of the slat zero position positioning can also be guaranteed. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] Due to the confined space and complex structure of the slat location, its zero-position cannot be directly determined. It is currently necessary to use a feeler gauge to measure the gap between the existing tooling and the aircraft structure to determine if the slat is in the zero-position state. This method not only fails to provide convenient zero-position location but also, due to the confined structure, cannot guarantee the consistency of the slat's zero-position. Therefore, overcoming the limitations of the confined space at the slat location and directly detecting the slat's zero-position is key to solving the aforementioned technical problems. The following section will combine... Figures 1 to 4 This invention provides a detailed description of the slat zero-position fixture.

[0036] Figure 1This diagram shows the structural schematic of the slat zero-position fixture provided in this embodiment. Figure 2 This diagram shows a cross-sectional view of the slat zero-position fixture provided in this embodiment. Figure 3 A schematic diagram of the slat zero-position fixture and guide rail provided in this embodiment is shown. Figures 1 to 3 As shown, the zero-position fixture for the slat 100 provided in this embodiment is used to position the slat 100 at its zero position. The slat 100 is slidably connected to the slide rail 200. The slat zero-position fixture includes a base 1 and a positioning member 2. The base 1 is fixedly connected to the slide rail 200 and has a first reference platform 11 for supporting the slat 100. The positioning member 2 includes a connecting arm 21 and a second reference platform 22. The connecting arm 21 is slidably connected to the base 1 and the connecting arm 21 is connected to the second reference platform 22. The connecting arm 21 can slide to allow the second reference platform 22 to switch between a positioning position abutting the slat 100 and a free position away from the slat 100. The connecting arm 21 is also marked with a scale arranged along its own sliding direction, which can read the scale corresponding to the positioning position of the second reference platform 22. Specifically, the slat 100 has two rolling bearings 101, which are coaxially arranged. The first reference platform 11 is used to support the outer ring surface of one rolling bearing 101, and the second reference platform 22 is used to abut against the outer ring surface of the other rolling bearing 101.

[0037] Preferably, the first reference stage 11 has a second support surface 111 for supporting the rolling bearing 101, the width D1 of the second support surface 111 being no greater than the outer ring wall thickness of the rolling bearing 101; and / or the second reference stage 22 has an abutment surface 221 for supporting the rolling bearing 101, the width D2 of the abutment surface 221 being no greater than the outer ring wall thickness of the rolling bearing 101, thereby preventing the reference stage from contacting other parts of the slide rail 200 and affecting the detection accuracy of the reference stage.

[0038] The zero-position fixture for the seam wing provided in this embodiment obtains a first measurement reference by fixing the base 1 to the slide rail 200 and having the first reference platform 11 support the seam wing 100. By marking a scale on the connecting arm 21 arranged along its sliding direction, the fixture allows the second reference platform 22 to be switched from a free position away from the seam wing 100 to a positioning position abutting the seam wing 100 after the connecting arm 21 slides. The scale corresponding to the positioning position of the second reference platform 22 can then be read, thereby locating the zero position of the seam wing 100. This allows the first measurement reference to be obtained during the disassembly, assembly, testing, or adjustment of the seam wing 100's installation position. Then, the connecting arm 21 is slid again to switch the second reference platform 22 from a free position away from the slat 100 to a positioning position abutting the slat 100. The scale corresponding to the second reference platform 22 in the positioning position is read again, and the installation position of the slat 100 is adjusted so that the scale corresponding to the second reference platform 22 in the positioning position for the second time is the same as the scale corresponding to the second reference platform 22 in the positioning position for the first time. This makes the zero position of the slat 100 the same in the two times. Thus, while realizing convenient positioning of the zero position of the slat 100, the sameness of the zero position positioning of the slat 100 can also be guaranteed.

[0039] Continue as Figures 1 to 3 As shown, the slide rail 200 has a first connecting hole 201, and the base 1 has a second connecting hole 12. The base 1 is detachably connected to the slide rail 200 by the locking assembly 3, thereby realizing the detachable connection between the sew wing zero-position fixture and the slide rail 200. After the sew wing 100 is disassembled or its installation position is adjusted for testing and re-determining the zero position of the sew wing 100, the sew wing zero-position fixture can be removed, thereby improving the ease of use of the sew wing zero-position fixture. Specifically, the locking assembly 3 includes a fastener 31 and a nut 32. The positioning rod 311 of the fastener 31 passes through the first connecting hole 201 and the second connecting hole 12. The positioning rod 311 is a threaded shaft. The nut 32 is threadedly connected to the positioning rod 311, thereby fixing the base 1 to the slide rail 200.

[0040] Preferably, a bushing 4 is also installed in the second connecting hole 12, and the positioning rod 311 is clearance-fitted with the bushing 4, thereby reducing the friction when the positioning rod 311 passes through the second connecting hole 12, preventing the positioning rod 311 from wearing out after long-term use, and extending the service life of the fastener 31.

[0041] Figure 4 It shows Figure 3 A magnified view of a portion of point A, as shown below. Figures 1 to 4As shown, a through hole 13 is also provided on the base 1. The connecting arm 21 is engaged with the through hole 13, thereby using the through hole 13 to constrain the sliding direction of the connecting arm 21, thereby preventing the connecting arm 21 from shifting during the sliding process, which in turn causes the scale value corresponding to the second reference platform 22 at the positioning position to change, thereby improving the positioning accuracy of the zero position of the slat 100 of the slat zero position fixture.

[0042] Continue as Figures 1 to 4 As shown, the second reference platform 22 has an abutting surface 221 for abutting the slat 100. When the second reference platform 22 is in the free position, the vertical distance H1 between the abutting surface 221 and the slat 100 is less than the length H2 of the connecting arm 21 extending out of the through hole 13. This prevents the connecting arm 21 from being fully inserted into the through hole 13 during the sliding process, which would cause the scale marked on the connecting arm 21 to be unable to be read normally, thereby improving the ease of operation of the slat zero-position fixture.

[0043] like Figures 1 to 3 As shown, the base 1 also has a first support surface 14. When the second reference platform 22 is in the free position, the first support surface 14 supports the second reference platform 22. Thus, after the slat zero-position fixture is fixedly connected to the slide rail 200, the second reference platform 22 can be maintained in the free position and can be switched from the free position to the positioning position at any time, thereby simplifying the operation difficulty of the slat zero-position fixture.

[0044] Preferably, the second reference platform 22 frequently needs to abut against the slat 100, and therefore frequently needs to withstand a certain amount of pressure. The second reference platform 22 is prone to deformation, which can affect the positioning accuracy of the slat zero-position fixture. To solve the above technical problem, a receiving groove 15 is also provided on the base 1. The bottom wall of the receiving groove 15 serves as the first support surface 14, allowing the receiving groove 15 to partially accommodate the positioning member 2. This allows for the placement of a larger volume positioning member 2 within a limited space, increasing the volume of the positioning member 2 and thus improving its structural strength, preventing deformation due to prolonged pressure.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
