[0002] The aerospace industry plays a vital role in the development of modern science and technology. The production and manufacturing of its equipment involves many complex processes and parts assembly processes.

However, it lacks flexibility when facing the diverse clamping needs of mounting plates of different shapes (such as circular and rectangular). For conventional shaped assembly plates such as circular mounting plates and rectangular mounting plates, specially designed circular or rectangular clamping structures are usually required to ensure a stable clamping effect. Moreover, when the rectangular mounting plate is rotated and replaced, the rotation of its edges and corners still requires the assemblers to move and make way, which not only increases the complexity of the operation and reduces work efficiency, but may also affect the assembly accuracy due to human movement, thus leaving room for improvement.

[0004] In order to avoid the above technical problems, it is necessary to provide an assembly device for aviation parts to overcome the above defects in the prior art. Summary of the invention

[0005] The object of the present invention is to provide an assembly device for aviation parts to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an assembly equipment for aviation parts, including a machine platform, a worm gear is rotatably arranged on the machine platform, a rotating machine disk is fixedly arranged on the worm gear, a movable groove is opened on the rotating machine disk, two threaded rods are rotatably arranged inside the movable groove, the opposite ends of the two threaded rods are fixedly connected, the thread directions of the two threaded rods are opposite, displacement blocks are threadedly connected to the two threaded rods, the two displacement blocks are slidably arranged in the movable groove, arc-shaped clamping blocks are fixedly arranged on the two displacement blocks, connecting blocks are fixedly arranged at both ends of each arc-shaped clamping block, and each connecting block is provided with a side rotating roller through the rotation of the arc rotating block.

[0007] As a preferred embodiment, a first pulley is fixedly provided on each of the side turning rollers, and two first motors are fixedly provided on each of the arc-shaped clamping blocks via a first fixing block.

[0008] As a preferred embodiment, a second pulley is fixedly provided on the output shaft of each of the first motors, and a transmission belt is provided between the first pulley and the second pulley on one side.

[0009] As a preferred embodiment, connecting blocks are fixedly provided at both ends of each arc-shaped clamping block, two elastic telescopic rods are fixedly provided on one side of each connecting block, and an electromagnetic block is fixedly provided at one end of the two elastic telescopic rods on one side.

[0010] As a preferred implementation, a second motor is provided at the rotation position of one end of the threaded rod, and the second motor is fixedly provided on one side of the rotating disk via a second fixing block.

[0011] As a preferred implementation scheme, a plurality of round protrusions are fixedly provided on the rotating machine plate, and a plurality of supporting legs are fixedly provided on the lower surface of the machine platform.

[0012] As a preferred embodiment, two third fixing blocks are fixedly arranged on the machine platform, and worms are arranged on adjacent sides of the two third fixing blocks for common rotation, and the worms are meshed with the worm wheel.

[0013] As a preferred embodiment, a third motor is provided at the rotation part of one end of the worm, and the third motor is fixed on one side of the third fixing block through a fourth fixing block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, when the two threaded rods are driven to rotate, since the threads are in opposite directions and the opposite ends are fixedly connected, the two displacement blocks threadedly connected thereto can realize precise movement toward or away from each other in the moving groove, thereby driving the two arc-shaped clamping blocks to clamp the circular mounting plate. At the same time, the spacing can be flexibly adjusted to meet the clamping requirements of mounting plates of different sizes. When facing a rectangular mounting plate, the arc-shaped clamping block can firmly clamp it through the side rotating rollers at both ends. At this time, these side rotating rollers can not only clamp the rectangular mounting plate in the arc-shaped clamping block, further enhancing the restriction on the side edges of the rectangular plate to prevent it from lateral displacement during the assembly process, but also when the side rotating rollers on the arc-shaped clamping block When the roller is driven to rotate, it can drive the clamped rectangular mounting plate to move. This feature enables the protruding edges of the rectangular mounting plate to be effectively adjusted and shrunk by the movement of the mounting plate driven by the side roller when the rectangular mounting plate is rotated on the rotating disk. Compared with the comparative documents, it not only realizes the equipment clamping of multi-shaped mounting plates, but also effectively reduces the manual moving and giving way operations required by the staff when the edges of the rectangular mounting plate are rotated, greatly reduces the interference of the staff, improves the degree of automation of the assembly process and the overall work efficiency, while also ensuring the accuracy and stability of the assembly, providing strong support for the high-quality assembly of aviation parts.

[0016] The present invention sets an electromagnetic block. When the two arc-shaped clamping blocks clamp the rectangular mounting plate with the help of the side-turning rollers, the electromagnetic blocks at both ends of the arc-shaped clamping blocks tightly fit the surface of the mounting plate. After the rectangular mounting plate is driven by the first motor and the position is adjusted by the side-turning rollers, the electromagnetic blocks are started. The powerful magnetic attraction function of the electromagnetic blocks significantly enhances the fixing stability of the rectangular mounting plate. This not only effectively prevents the displacement of the mounting plate due to external interference during the assembly process, provides a solid guarantee for precise assembly, greatly improves the assembly accuracy and quality, but also ensures the smooth progress of the installation process in subsequent component installation operations.

[0017] In the present invention, the elastic telescopic rod on one side of the electromagnetic block plays an indispensable role in buffering and adaptive adjustment. When the side-turning roller drives the rectangular mounting plate to perform conveying displacement, the elastic telescopic rod flexibly elastically expands and contracts according to the movement status of the mounting plate. On the one hand, it cleverly absorbs and compensates for the additional resistance caused by the magnetic attraction of the electromagnetic block, so that the side-turning roller can smoothly drive the mounting plate to move, ensuring that the entire driving and conveying process is smooth and efficient; on the other hand, relying on its elastic characteristics, the elastic telescopic rod can adapt to rectangular mounting plates of different thicknesses and materials, ensuring that the electromagnetic block is always tightly attached to the mounting plate with appropriate pressure, further enhancing the clamping adaptability of the equipment to various rectangular mounting plates, effectively expanding the application scope of the equipment in the field of aviation parts assembly, and strongly promoting the development and progress of aviation parts assembly technology.

[0018] According to the present invention, when the mounting plate is placed on these round protrusions, whether it is a round mounting plate or a rectangular mounting plate, only a small contact area is formed with the round protrusions during movement, displacement and replacement operations, which effectively reduces the hindrance of friction, so that the mounting plate can be rotated and displaced more smoothly, greatly improves the flexibility and accuracy of rotation, and helps to achieve precise assembly of aviation parts on the round mounting plate. At the same time, when replacing the mounting plate, the smaller contact area also facilitates the rapid loading and unloading of the mounting plate, reduces the adsorption or jamming phenomenon that may be caused by excessive contact area, and further improves the convenience of operation. In addition, the provision of the round protrusions can also avoid scratches or damages that may be caused by large-area contact between the mounting plate and the rotating disk during movement, effectively protecting the surface quality of the mounting plate, ensuring that the assembly of aviation parts is not affected, and improving the overall quality and reliability of the product, thereby showing excellent performance in the assembly process of aviation parts, and effectively promoting the efficient and accurate assembly work.

The arc-shaped clamping block 7 can clamp the rectangular mounting plate firmly through the side rollers 10 at both ends. At this time, these side rollers 10 can not only clamp the rectangular mounting plate on the arc-shaped clamping block 7, further strengthen the restriction on the side of the rectangular plate, and prevent it from lateral displacement during assembly, but also when the side rollers 10 on the arc-shaped clamping block 7 are driven to rotate, they can drive the clamped rectangular mounting plate to move. This feature enables the protruding edges of the rectangular mounting plate to be effectively adjusted and contracted by the movement of the mounting plate driven by the side rollers 10 when the rectangular mounting plate is rotated on the rotating disk 3. Compared with the comparative documents, it not only realizes the equipment clamping of multi-shaped mounting plates, but also effectively reduces the manual moving and giving way operations required by the staff when the edges of the rectangular mounting plate are rotated, which greatly reduces the interference of the staff, improves the degree of automation and overall work efficiency of the assembly process, and also ensures the accuracy and stability of the assembly, providing strong support for the high-quality assembly of aviation parts.

[0029] like Figure 3 As shown, the present invention provides an embodiment, a first pulley 11 is fixedly provided on each side turning roller 10 , and two first motors 13 are fixedly provided on each arc-shaped clamping block 7 via a first fixing block 12 .

[0030] like Figure 3As shown, the present invention provides an embodiment, the output shaft of each first motor 13 is fixedly provided with a second pulley 14, and a transmission belt 15 is arranged between the first pulley 11 and the second pulley 14 on one side.

[0031] like Figure 3 As shown, the present invention provides an embodiment, each arc-shaped clamping block 7 is fixedly provided with a connecting block 26 at both ends, and each connecting block 26 is fixedly provided with two elastic telescopic rods 16 on one side, and one end of the two elastic telescopic rods 16 on one side is jointly fixedly provided with an electromagnetic block 17. By setting the electromagnetic block 17, when the two arc-shaped clamping blocks 7 clamp the rectangular mounting plate with the help of the side-turning roller 10, the electromagnetic blocks 17 at both ends of the arc-shaped clamping blocks 7 are tightly fitted to the surface of the mounting plate. After the rectangular mounting plate is driven by the first motor 13 and the position is adjusted by the side-turning roller 10, the electromagnetic block 17 is started, and its powerful magnetic attraction function significantly enhances the fixing stability of the rectangular mounting plate. This not only effectively prevents the displacement of the mounting plate caused by external interference during the assembly process, provides a solid guarantee for precise assembly, and greatly improves the assembly accuracy and quality, but also in the subsequent component installation operations, it is ensured that In addition, the elastic telescopic rod 16 on one side of the electromagnetic block 17 plays an indispensable role in buffering and adaptive adjustment. When the side-turning roller 10 drives the rectangular mounting plate to transport and move, the elastic telescopic rod 16 flexibly retracts and contracts according to the movement of the mounting plate. On the one hand, it cleverly absorbs and compensates for the additional resistance caused by the magnetic attraction of the electromagnetic block 17, so that the side-turning roller 10 can smoothly drive the mounting plate to move, ensuring that the entire driving and conveying process is smooth and efficient; on the other hand, relying on its elastic characteristics, the elastic telescopic rod 16 can adapt to rectangular mounting plates of different thicknesses and materials, ensuring that the electromagnetic block 17 is always tightly attached to the mounting plate with appropriate pressure, further enhancing the equipment's adaptability to clamping various rectangular mounting plates, effectively expanding the equipment's application scope in the field of aviation parts assembly, and strongly promoting the development and progress of aviation parts assembly technology.

[0032] like Figure 6 As shown, the present invention provides an embodiment, a second motor 18 is arranged at the rotation position of one end of the threaded rod 5 , and the second motor 18 is fixedly arranged on one side of the rotating disk 3 through a second fixing block 19 .

[0033] like Figure 6As shown, the present invention provides an embodiment, a plurality of round protrusions 20 are fixedly arranged on the rotating machine plate 3, and a plurality of supporting legs 25 are fixedly arranged on the lower surface of the machine table 1. By arranging the round protrusions 20, when the mounting plate is placed on these round protrusions 20, whether it is a round mounting plate or a rectangular mounting plate, when performing movement, transposition and replacement operations, only a small contact area is formed with the round protrusions 20, which effectively reduces the resistance of friction, so that the mounting plate can perform the rotation and transposition operation more smoothly, greatly improving the flexibility and accuracy of the rotation, and facilitating the accurate installation of aviation parts on the round mounting plate. At the same time, when replacing the mounting plate, the smaller contact area also facilitates the quick loading and unloading of the mounting plate, reduces the adsorption or jamming phenomenon that may be caused by excessive contact area, and further improves the convenience of operation. In addition, the provision of the circular protrusion 20 can also avoid scratches or damages that may be caused by large-area contact between the mounting plate and the rotating disk 3 during movement, effectively protecting the surface quality of the mounting plate, ensuring that the assembly of aviation parts is not affected, and improving the overall quality and reliability of the product, thereby showing excellent performance in the assembly process of aviation parts, and effectively promoting the efficient and accurate assembly work.

[0034] like Figure 6 As shown, the present invention provides an embodiment, two third fixing blocks 21 are fixedly provided on the machine table 1, and worms 22 are provided on adjacent sides of the two third fixing blocks 21 for common rotation, and the worms 22 are meshed with the worm wheel 2.

[0035] like Figure 6 As shown, the present invention provides an embodiment, a third motor 23 is arranged at the rotation part of one end of the worm 22, and the third motor 23 is fixedly arranged on one side of the third fixing block 21 through a fourth fixing block 24.

[0036] The working principle and use process of the present invention are as follows: First, according to the shape of the circular or rectangular mounting plate to be assembled, the spacing of the arc-shaped clamping blocks 7 is preliminarily adjusted. By starting the second motor 18, the second motor 18 drives the threaded rod 5 connected thereto to rotate. Since the two threaded rods 5 have opposite thread directions and the opposite ends are fixedly connected, the two displacement blocks 6 will move toward or away from each other in the moving groove 4, thereby driving the arc-shaped clamping blocks 7 to adjust to a roughly appropriate position, in preparation for placing the mounting plate. For a circular mounting plate, place it on a plurality of circular protrusions 20 on the rotating machine disk 3. Start the second motor 18 to further fine-tune the position of the arc-shaped clamping blocks 7, so that the two arc-shaped clamping blocks 7 fit closely to the circumference of the circular mounting plate, and achieve preliminary clamping of the circular mounting plate. For a rectangular mounting plate, place it on the circular protrusions 20 as well. Adjust the arc-shaped clamping blocks 7 so that they clamp the rectangular mounting plate from both sides. At this time, the side of the rectangular mounting plate contacts the side turning roller 10. Then the first motor 13 is started, and the output shaft of the first motor 13 drives the second pulley 14 to rotate, and the first pulley 11 is driven to rotate through the transmission belt 15, thereby rotating the side roller 10. When the side roller 10 rotates, it can drive the rectangular mounting plate to move between the arc clamping blocks 7 for fine adjustment, so that the rectangular mounting plate is in the best assembly position. Then, the electromagnetic block 17 is started, and the electromagnetic block 17 produces a magnetic attraction to tightly adsorb and fix the rectangular mounting plate. At the same time, the elastic telescopic rod 16 will elastically expand and contract according to the adsorption between the electromagnetic block 17 and the mounting plate, ensuring that the electromagnetic block 17 is stably adsorbed without affecting the driving and conveying displacement of the side roller 10. When the mounting plate needs to be rotated and reversed, the third motor 23 is started, and the third motor 23 drives the worm 22 to rotate, and the worm 22 and the worm wheel 2 are meshed with each other, thereby driving the worm wheel 2 to rotate, and the rotating disc 3 on the worm wheel 2 rotates accordingly, thereby causing the mounting plate to rotate smoothly. During the rotation process, the arc clamping block 7 and the side roller 10 always maintain a stable clamping of the rectangular mounting plate. For the rectangular mounting plate, its edges and corners can pass smoothly when rotating due to the existence of the side-turning roller 10 and the previous fixing and buffering effect of the electromagnetic block 17 and the elastic telescopic rod 16, without the need for manual movement by the staff. When the assembly is completed, if it is a rectangular mounting plate, turn off the electromagnetic block 17, and then start the first motor 13 again to make the side-turning roller 10 rotate in the opposite direction, and adjust the rectangular mounting plate to a position that is easy to disassemble. For the circular mounting plate, the spacing of the arc-shaped clamping block 7 can be appropriately adjusted by rotating the second motor 18 in the opposite direction, and the arc-shaped clamping block 7 can be directly loosened, and then the mounting plate can be removed from the round protrusion 20.
