Description

Technical Field

[0001] The invention belongs to the technical field of precision rotating component manufacturing, and in particular relates to a thin-walled rotating component correction device and method. Background Art

[0002] Thin-walled rotating components are widely used in the aerospace field and are numerous. With the development trend of precision and lightweight, many cabin products have extremely thin skin walls and poor end frame structural rigidity while meeting the strength requirements. This also causes such weak rigid parts to be easily deformed during the actual production process. Since the cabins need to be assembled and docked, and bolts and hexagonal prisms are used to connect and tighten, the docking part size and roundness of the cabins are required to be high. Therefore, when the docking end of the cabin is deformed or the circular cross-section becomes an elliptical cross-section, that is, the roundness does not meet the requirements, it will cause the cabins to be unable to be assembled in place, which will not only affect their continued assembly, but may even lead to consequences such as product scrapping. In the prior art, after the semi-finishing is completed, the length of the strut extension is usually estimated based on experience according to the different deformation amounts of each product, and a simple adjustable strut is used to support and hit with a hammer, and the operation is repeated until the roundness meets the design requirements after the strut is removed, and the correction is completed.

[0003] For example, the patent document with the publication number CN219130397U specifically discloses a device for correcting circular thin-walled parts, including a rotary seat sleeve, one end of the rotary seat sleeve is rotatably connected to a push rod, the end of the rotary seat sleeve away from the push rod is threadedly connected to a support rod, the push rod and the support rod are coaxial, and the support rod and the end of the push rod away from the rotary seat sleeve are both connected to an arc support block, and the ends of the two arc support blocks away from the rotary seat sleeve match the inner wall curvature of the circular thin-walled parts. The threaded self-locking principle of the rotary seat sleeve and the support rod is used to make the threaded parts of the rotary seat sleeve and the support rod of the device in a self-locking and tightening state. Although the purpose of correction can be achieved, the arc support block of the device is prone to displacement, rotation, and looseness during the correction process, lacks a limiting mechanism, and is prone to falling and damaging the product during the correction process, affecting product quality and causing correction failure.

[0004] Another example is the patent document with the publication number CN215509903U, which specifically discloses a thin-walled parts calibration tool, including a connecting block and a pad, a plurality of fixing rods are fixedly installed around the outer wall of the connecting block, a threaded groove is provided in the middle of the outer side of the fixing rod, a screw is provided in the inner cavity of the threaded groove, a fixing plate is provided at the upper end of the connecting block, and a plurality of infrared receivers are fixedly installed at the lower end of the fixing plate. Although the calibration purpose can be achieved, the pad is still prone to displacement, rotation, and loosening during the calibration process, and the lack of a limiting mechanism affects the product quality and leads to calibration failure.

[0005] In summary, the existing technical solutions have the problem that the parts in contact with the inner wall of the product lack a limiting mechanism, which makes it easy for them to shift, rotate, and become loose during the calibration process, and it is easy for them to fall and damage the product, thus affecting the technical problem of product quality.

[0006] Therefore, there is an urgent need to design a thin-walled rotating component correction device and method with a simple structure, reliable limit, and components that are not easy to rotate or shake during operation, which has an anti-falling effect, is easy to operate, and has high reliability.

Figure 1 -Attached Fig.11 The specific implementation of the present invention is described in detail.

[0044] like Figure 1-Figure 11 As shown, an embodiment of the present invention provides a thin-walled rotary component correction device, a rotary seat wing 1, the rotary seat wing 1 includes a flat plate 11 and a hollow threaded sleeve 12, the flat plate 11 and the hollow threaded sleeve 12 are cross-mounted on the rotary component 4, the two ends of the hollow threaded sleeve 12 are respectively connected with adjustment struts 2, the adjustment struts 2 are respectively mounted on the inner side of the rotary component 4 through support blocks 3, the support blocks 3 are hung on the orifices of the rotary component 4, and are tightly attached to the inner wall of the rotary component 4. By setting the support block 3 to hang on the orifice of the rotary component 4, during the correction process, the correction device will not fall or loosen due to uneven force, thereby improving the overall reliability of the correction device. The correction device is as follows Figure 2-Figure 4 As shown, the support block 3 is as Figure 9-11 shown.

[0045] In this embodiment, the support block 3 includes a base 31, an arc block 32 and a cylinder B33. The arc block 32 is arranged on the base 31, and the cylinder B33 is arranged on the side of the arc block 32 facing away from the arc surface 321 for installing the adjustment support rod 2.

[0046] In this embodiment, a mounting platform for hanging the support block 3 on the rotating member 4 is reserved on one side of the arc surface 321 on the base 31, the arc surface 321 is in close contact with the inner wall of the rotating member 4, and the mounting platform is hung on the hole of the rotating member 4. By setting the mounting platform, the correction device can be hung on the hole of the rotating member 4, which plays the role of limiting, fixing and supporting, improves the correction reliability of the correction device, and is not easy to fall or loosen during correction.

[0047] In this embodiment, a blind hole 34 is provided on the cylinder B33, and the blind hole 34 penetrates into the arc block 32. The blind hole 34 can improve the reliability of the connection between the adjustment support rod 2 and the support block 3 and the convenience of disassembly and assembly. On the other hand, the blind hole 34 is used to fix one end of the adjustment support rod 2. When the adjustment support rod 2 is adjusted during the calibration process, only the connection end between the rotating seat wing 1 and the adjustment support rod 2 changes. The blind hole 34 is as shown in FIG. Fig. 9 and Fig.11 shown.

[0048] In this embodiment, the length of the plate 11 is greater than the diameter of the hole of the rotating member 4, and the width is less than the length of the hollow threaded sleeve 12. During calibration, the two ends of the plate 11 are placed on the end surface of the hole of the rotating member 4, which plays the role of limiting and preventing falling and radial support, so that the calibration device always maintains a horizontal state. During calibration, the plate 11 and the base 31 are on the same plane. Figure 5-7 shown.

[0049] In this embodiment, the inner wall of the hollow threaded sleeve 12 is provided with threads for mounting the adjusting strut 2 and can cooperate with the adjusting strut 2 to adjust the correction diameter of the correction device.

[0050] In this embodiment, the adjustment strut 2 includes a stud 21, a hexagonal prism 22 and a cylinder A23, and the stud 21, the hexagonal prism 22 and the cylinder A23 are integrally formed in sequence. When adjusting the correction diameter of the correction device, rotating the hexagonal prism 22 can drive the stud 21 to rotate in and out of the hollow threaded sleeve 12, so as to achieve the purpose of adjusting the correction diameter. When the stud 21 is completely screwed into the hollow threaded sleeve 12, it is the minimum diameter that the correction device can correct. When the stud 21 is screwed into one-third of the hollow threaded sleeve 12, it is the maximum diameter that the correction device can correct. A variety of correction requirements with different diameters can be used, and the application range is wide. The adjustment strut 2 is as follows: Figure 8 shown.

[0051] In this embodiment, the stud 21 is threadedly connected to the hollow threaded sleeve 12.

At the same time, the threaded connection facilitates the adjustment of the correction diameter of the correction device during the correction process. The internal thread of the hollow threaded sleeve 12 is M24, with a pitch of 3mm; the external thread of the stud 21 is M24, with a pitch of 3mm.

[0052] In this embodiment, the cylinder A23 is connected to the blind hole 34 by plugging. This structure is set to ensure the reliability of the connection while improving the convenience of disassembly and assembly, and fix one end of the adjustment strut 2 so that when the hexagonal prism 22 is rotated, the adjustment strut 2 can be screwed in and out of the hollow threaded sleeve 12 to adjust the correction diameter of the correction device. The diameter of the cylinder A23 is smaller than the diameter of the blind hole 34, so as to form a plug-in connection. The diameter of the cylinder A23 is 16 mm, and the diameter of the blind hole 34 is 18 mm.

[0053] In an embodiment of the present invention, a calibration method for a thin-walled rotating component calibration device is provided, comprising the following steps:

[0054] S01 Determine the correction support direction: Obtain the diameters of no less than 8 different positions of the orifice of the rotating member 4 by measuring tools, mark them, obtain the position with the smallest diameter value by comparing the diameter data, and determine that the position with the smallest diameter value is the correction support direction; the measuring tool is, for example, a vernier caliper, etc.

[0055] S02 Place the calibration device: Hang the support block 3 of the calibration device on both ends of the calibration support direction respectively, so that the arc surface 321 fits with the inner wall of the hole of the rotating member 4, and the two ends of the flat plate 11 are placed on the end surface of the hole of the rotating member 4 with an angle of 90 degrees with the calibration support direction, and keep the central axis of the hollow threaded sleeve 12 consistent with the calibration support direction. The calibration device is placed as shown in the following figure. Figure 1 As shown;

[0056] S03 Correction: By using a wrench to rotate the hexagonal prism 22, the length of the correction device in the correction support direction is increased or shortened, thereby expanding the inner contour of the rotating member 4 in the correction support direction, and at the same time, the outer contour of the rotating member 4 is repeatedly struck with a hammer to release the internal stress generated by the deformation in the form of vibration, so that the outer contour of the rotating member 4 undergoes plastic deformation; the correction state is as follows Figure 1 When the hexagonal prism 22 is rotated by a wrench, the hexagonal prism 22 on both sides of the hollow threaded sleeve 12 rotates leftward and rightward respectively, so as to keep the calibration device stable.

[0057] S04 re-measurement: After the outer contour of the rotating member 4 undergoes plastic deformation, the correction device is removed, and the diameter in the correction support direction is re-measured to determine whether it meets the design requirements of the drawing. If so, the correction is completed. If not, steps S01-S04 are repeated until it meets the design requirements.

[0058] The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
