The first mounting base surface 10 and the second mounting base surface 11 are relatively arranged on the outer ring of the measuring reference part 3. The mounting surface of the first mounting plate 12 and the mounting surface of the second mounting plate 13 are respectively installed and movably rotated on the first mounting base surface 10 and the second mounting base surface 11. The first mounting plate 12 extends from the first mounting base surface 10 toward the inner ring of the measuring reference part 3.

[0037] The working process of the first mounting plate 12 and the second mounting plate 13 in the assembly inspection fixture of the tail wing fixing plate provided in this embodiment is as follows: the first mounting base 10 and the second mounting base 11 are relatively mounted on the outer ring, and the first mounting plate 12 and the second mounting plate 13 are respectively mounted on the first mounting base 10 and the second mounting base 11, so that the first mounting plate 12 and the second mounting plate 13 are relatively arranged on the outer ring. When inspecting different states of the same part of the product, one of the mounting plates can be positioned on the mounting base, and then the mounting plate extending to the inner ring is tightly fitted to the part of the product to be inspected, and then the measuring piece is inserted into the inspection hole and inspected with the product's inspection hole. At the same time, the other mounting plate can be flexibly flipped open to avoid the part of the product that affects the inspection operation of the product state. When the product is changed to another state, the originally positioned mounting plate can be flipped back to the originally opened mounting plate and positioned on the mounting base for inspection.

[0038] The tail wing mounting plate assembly inspection fixture also includes a flipping mechanism 16, secured to the workbench 1 and attached to the outer ring of the measurement reference member 3. In this embodiment, flipping mechanism 16 is used to flip the positioning rod 7, first mounting plate 12, and second mounting plate 13. This mechanism 16 facilitates the flipping of the positioning rod 7, first mounting plate 12, and second mounting plate 13. This significantly improves operational efficiency during inspection, reduces the time and effort required for manual adjustments, and further enhances operational accuracy and stability.

[0039] Preferably, the workbench 1 is provided with a stand 31, which is used to support the flipping mechanism 16. The height of the stand 31 can be set according to the height of the part to be tested on the product. By installing the stand 31, the vertical position of the flipping mechanism 16 and related detection components can be flexibly adjusted to make it accurately fit the part to be tested on the product, ensuring that the detection operation is carried out within the most suitable height range.

[0040] Preferably, the flipping mechanism 16 may be composed of a toggle clamp 17 , or may be composed of a base 18 , a connecting plate 19 and a fastener 20 .

[0041] Specifically, the flipping mechanism 16 is composed of an elbow-type clamp 17. The positioning end of the elbow-type clamp 17 is positioned on the workbench 1. The positioning end of the elbow-type clamp 17 can also be positioned on the stand 31. The clamping end of the elbow-type clamp 17 is used to install the positioning rod 7, the first mounting plate 12 and the second mounting plate 13. The elbow-type clamp 17 has a good self-locking function. Once clamped, it can effectively prevent the displacement or loosening of components of the product due to factors such as vibration and external interference during the inspection process, thereby ensuring the accuracy and reliability of the inspection data. It is easy to operate and only requires a small operating force to achieve the clamping and loosening actions, which reduces the labor intensity of the operator and improves work efficiency. Moreover, the elbow-type clamp 17 has a compact structure and occupies a small space, which is conducive to the rational layout of the inspection system on the limited workbench 1, making the entire inspection device more simple and efficient.

[0042] Specifically, the flipping mechanism 16 is provided with at least three parts, including a base 18, a connecting plate 19, and a fastener 20. The base 18 is provided on the workbench 1 and can also be positioned on the stand 31. The base 18 is fixed to the outer ring of the measuring reference part 3. The base 18 can provide a stable support and movement base for the positioning rod 7, the first mounting plate 12, and the second mounting plate 13. One end of the connecting plate 19 is movably connected to the top of the base 18. The connecting plate 19 and the base 18 are connected by a rotating shaft 33. The other end of the connecting plate 19 extends from the base 18 to the top of the inner ring of the measuring reference part 3. The fastener 20 is rotatably positioned between the connecting plate 19 and the base 18. The fastener 20 is screwed into the interior of the base 18 from the top of the connecting plate 19. The fastener 20 can be a screw. In this embodiment, the connecting plate 19 can be used to install the positioning rod 7, the first mounting plate 12, and the second mounting plate 13, and achieve the flipping effect of the positioning rod 7, the first mounting plate 12, and the second mounting plate 13.

[0043] In this embodiment, the first mounting plate 12 and the second mounting plate 13 are installed on the lower end surface of the connecting plate 19, and the lower end surface of the connecting plate 19 is a horizontal base surface, and the matching surfaces of the first mounting plate 12 and the second mounting plate 13 can be changed according to product requirements, such as the inclination angle, thereby improving the adaptability of the measurement.

[0044] In this embodiment, the positioning rod 7 is also mounted on the lower end surface of the connecting plate 19. Multiple measuring holes 8 can be added to the positioning rod 7 based on product requirements. Specifically, the middle portion of the positioning rod 7 is connected to the connecting plate 19, while the measuring holes 8 are located at both ends of the positioning rod 7. This secure connection between the positioning rod 7 and the connecting plate 19 and the design of multiple measuring holes 8 not only allows the installation position of the positioning rod 7 to be precisely determined based on the specific testing requirements of the product, ensuring stability and reliability during testing, but also expands the scope of testing by providing multiple measuring holes 8.

[0045] Preferably, the positioning rod 7 and the measuring hole 8 can be used separately to measure the product hole position. The positioning rod 7 extends to the upper end of the product to be measured, and the center line of the measuring hole 8 coincides with the center line of the product's hole to be measured. When the connecting plate 19 or the clamp positions the positioning rod 7, the measuring core shaft is inserted into the hole to be measured and the measuring hole 8 to test whether the product is qualified.

[0046] Preferably, the positioning seat 5 and the matching hole 6 can be used separately to measure the hole position of the product. In this embodiment, the positioning seat 5 is positioned at the position of the product to be tested, the top surface of the positioning seat 5 supports the product, and the matching hole 6 cooperates with the hole position to be measured of the product. At this time, the measuring mandrel on the workbench 1 can be inserted into the hole position to be measured and the matching hole 6 to test whether the product is qualified.

[0047] Specifically, a frame plate 32 can be installed on the workbench 1 to position the measuring reference part 3. A gap between the measuring reference part 3 and the product contour is left when the measuring reference part 3 is installed. During measurement, the product is positioned on the positioning rod 7 and pressed tightly. A go / no-go gauge can be used to penetrate the gap and slide in the gap to measure whether the product contour line is qualified.

[0048] The assembly inspection fixture for the tail wing fixing plate also includes a support base 21 and a positioning hole 22, which are arranged on the workbench 1. The positioning hole 22 extends through the support base 21. The support rod 2 is mounted on the support base 21. The support base 21 is used to install and support the support rod 2. The support rod 2 includes a rod body 23 and a spring 24. The middle portion of the rod body 23 is inserted into the positioning hole 22, and both ends of the rod body 23 pass through the positioning hole 22. The spring 24 is mounted on one end of the rod body 23. The diameter of the two ends of the rod body 23 is larger than the diameter of the positioning hole 22. The two ends of the spring 24 respectively abut against one end of the rod body 23 and the side of the mounting positioning hole 22 of the support base 21.

[0049] Preferably, when the support rod 2 is vertically installed on the positioning hole 22, the two ends of the spring 24 are fixedly connected to the bottom end of the support rod 2 and the bottom surface of the support seat 21, respectively. At this time, the spring 24 adopts a compression spring 24. When the product is pressed to the top of the support rod 2, the bottom end of the support rod 2 stretches the spring 24, which can buffer the impact of external force and avoid damage to components. It can also adapt to the position differences of different products and stably support the products.

[0050] Preferably, a shaft sleeve 34 can be installed between the support rod 2 and the positioning hole 22 to improve the smoothness and stability of the movement of the support rod 2 in the positioning hole 22 and reduce the friction and wear between the two, thereby ensuring that the tail wing fixing plate always maintains a stable support state during the detection process and improves the detection accuracy.

[0051] The assembly inspection fixture of the tail wing fixing plate also includes a storage box 25, which is set on the workbench 1. The storage box 25 is used to place the measuring instrument. The storage box 25 includes a box body 26 and a cover body 27. The box body 26 is set on the workbench 1. The interior of the box body 26 is provided with a mounting groove for matching the measuring instrument. The groove surface of the mounting groove matches the shape of the measuring instrument. The cover body 27 is detachably set on the box body 26, and the cover body 27 covers the box body 26. By setting up a special storage box 25 to accommodate the measuring instrument and utilizing the mounting groove in the box body 26 that matches the shape of the measuring instrument, it is possible to provide a precise and stable storage location for the measuring instrument during the inspection process. When the inspection work is paused or completed, the measuring instrument is properly placed in the mounting groove, which can effectively prevent the measuring instrument from being subjected to physical damage such as collisions and scratches due to random placement, ensuring that its measurement accuracy is not affected.

[0052] The tail wing mounting plate assembly inspection fixture also includes a measuring tool 28, mounted on workbench 1. This tool can be a go / no-go gauge, used to measure the product's positioning accuracy. This specialized measuring tool 28 enables precise measurement of the tail wing mounting plate's positioning accuracy, capturing key data for evaluating product quality and machining accuracy, providing an effective basis for subsequent adjustments and improvements.

[0053] The tail wing mounting plate assembly inspection fixture also includes a base frame 29 and pulleys 30. The base frame 29 is mounted on the bottom of the workbench 1, and the pulleys 30 are mounted on the bottom of the base frame 29. The base frame 29 and pulleys 30 are used to slide the workbench 1. During inspection, the position of the workbench 1 can be easily adjusted to better coordinate with other inspection equipment and operating areas, reducing the tedious manual handling and rearrangement, and improving the overall efficiency and smoothness of the inspection process.
