Description

Technical Field

[0001] This invention relates to the field of aircraft assembly technology, specifically to a docking device and method for accurately improving the docking of intersection points. Background Technology

[0002] In the aircraft assembly phase, numerous components or finished products are involved in their mating and installation, most of which play a crucial role in the aircraft's assembly precision. Therefore, the installation accuracy of these components or finished products is paramount. During the mating and installation process in the assembly phase, a docking device is required for assembly and connection. This is particularly true for the assembly of the aircraft main beam, whose installation location is generally the intersection hole of the main beam, and whose mating position is the symmetrical intersection of a ring-shaped plane and a horizontal plane. During the docking process, it is difficult to find the theoretically horizontal plane, requiring multiple adjustments to ensure the accuracy and precision of the positioning. These adjustments can easily damage the aircraft main beam. Current assembly and docking methods are insufficient to meet design requirements. The need for multiple alignment adjustments during docking leads to low work efficiency and high labor intensity. Therefore, to address these issues, a docking device has been designed to meet the usage requirements. Summary of the Invention

[0003] The technical problem to be solved by this invention is to address the problems existing in the background art, and thus proposes a docking device. This docking device is used to assemble the intersection holes of the aircraft main beam, so that the intersection holes of the aircraft main beam are connected to the pin shaft and mated to the support. Under the premise of ensuring accuracy, natural assembly is achieved. This not only accurately improves the docking accuracy of the intersection, but also facilitates operation and use and improves work efficiency. Specifically, it is a docking device and docking method for accurately improving the docking of intersections.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a docking device for accurately improving the docking of intersection points, comprising a base, a pin, a support, a bumper block, a step pin, a mating block, and a connecting nut. Two supports are arranged at intervals on the base, and a receiving cavity is formed between the two supports and the base. The mating block is connected to the support through the step pin, and the connecting nut is screwed onto the step pin. A mating hole matching the pin is also provided between the mating block and the support. The two supports and the mating block are connected by the pin, and the bumper block is fitted into the pin located above the receiving cavity.

[0005] Furthermore, in the docking device for accurately improving the intersection of the joints described in this invention, the support has two upwardly protruding connecting ears, which are symmetrically arranged at the middle of both ends of the support, and a through hole matching the stepped pin is provided in the connecting ear; while the two ends of the mating block are provided with opening slots matching the connecting ears, and connecting holes matching the stepped pin are provided on both sides of the opening slots. The mating block is set on the support through the opening slots, and the stepped pin passes through the connecting hole and the through hole, and is screwed onto the stepped pin by a connecting nut, so as to realize the detachable connection between the mating block and the support.

[0006] Furthermore, in the docking device for accurately improving the intersection docking described in this invention, there are two pins and two mating holes. The two mating holes are arranged at intervals between the mating block and the support. The two pins pass through the corresponding mating holes and are arranged in parallel above the receiving cavity. The two pins enable a detachable connection between the two spaced-apart supports and the mating block.

[0007] Furthermore, in the docking device described in this invention for accurately improving the docking of intersection points, the mating hole is composed of an upper semi-circular hole and a lower semi-circular hole forming a circular hole structure. The upper semi-circular hole is located at the bottom of the mating block, while the lower semi-circular hole is located at the top of the support and corresponds to the position of the upper semi-circular hole.

[0008] Furthermore, in the docking device for accurately improving the docking of the intersection point as described in this invention, two anti-collision blocks are provided. The two anti-collision blocks are placed in opposite positions in the two pins above the receiving cavity and can move left and right along the pins. One anti-collision block can contact and connect with the mating block and support (3) on one side of the receiving cavity, and the other anti-collision block can contact and connect with the mating block and support on the other side of the receiving cavity.

[0009] This invention also discloses a docking method for the aforementioned docking device that accurately improves the docking of intersections, the docking method comprising the following steps: S1. First, set the base on the docking equipment used for assembling the main beam of the aircraft, then place the mating block on the support in the base, and finally connect the mating block and the support with a stepped pin. S2. Using a pin that passes through the mating hole on one side of the receiving cavity, first place the anti-collision block on the pin, then pass the pin through the intersection hole in the aircraft main beam, then place another anti-collision block on the pin, then pass the pin through the mating hole on the other side of the receiving cavity, and finally fix the pin, thereby realizing the docking connection of the aircraft main beam. The two anti-collision blocks placed on the pin can prevent the aircraft main beam from being damaged. S3. The step pin is fixedly connected by a connecting nut to prevent relative movement between the mating block and the support, thereby achieving the mating connection of the intersection hole of the aircraft main beam.

[0010] Compared with existing technologies, the docking device and method described in this invention offer several advantages: First, the base is adjusted to the accurate position. Then, the cavity formed between the support and the base serves as the installation position. Under the action of the pin, the aircraft main beam's intersection holes can be aligned and assembled. Natural assembly is achieved while ensuring accuracy. Simultaneously, the anti-collision block fitted on the pin prevents damage to the aircraft main beam during the docking adjustment process, protecting it. The step pin connects the block and the support, facilitating installation and disassembly. Therefore, the docking device and method described in this invention not only enable convenient and quick installation and disassembly but also allow for rapid and accurate position adjustment, improving the installation accuracy of components or finished products and accurately reflecting the actual installation angle. This provides support for subsequent aircraft component assembly. Its overall structure is simple, easy to operate and use, and suitable for widespread application. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the embodiments thereof. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1

[0015] like Figures 1 to 3As shown, this embodiment provides a docking device for accurately improving the docking of intersections, including a base 1, a pin 2, a support 3, a bumper block 4, a stepped pin 5, a mating block 6, and a connecting nut 7. Two spaced-apart supports 3 are provided on the base 1, and a receiving cavity is formed between the two supports 3 and the base 1. The mating block 6 is connected to the support 3 through the stepped pin 5, and the connecting nut 7 is screwed onto the stepped pin 5. A mating hole matching the pin 2 is also provided between the mating block 6 and the support 3. The two spaced-apart supports 3 and the mating block 6 are connected by the pin 2. The bumper block 4 is fitted into the pin 2 located above the receiving cavity.

[0016] Furthermore, in the docking device described in this embodiment for accurately improving the connection point, the support 3 has two upwardly protruding connecting ears 31, which are symmetrically arranged at the middle of both ends of the support 3. Each connecting ear 31 has a through hole that matches the stepped pin 5. At both ends of the mating block 6, there are opening grooves 61 that match the connecting ears 31, and connecting holes that match the stepped pin 5 are provided on both sides of the opening grooves 61. The mating block 6 is mounted on the support 3 through the opening grooves 61, passes through the connecting holes and through holes via the stepped pin 5, and is screwed onto the stepped pin 5 by a connecting nut 7, thus achieving a detachable connection between the mating block 6 and the support 3.

[0017] Furthermore, in the docking device described in this embodiment for accurately improving the connection point, two pins 2 are provided, and two mating holes are provided. The two mating holes are arranged at intervals between the mating block 6 and the support 3. The two pins 2 pass through the corresponding mating holes and are arranged in parallel above the receiving cavity. The two spaced-apart supports 3 and mating blocks 6 are detachably connected by the two pins 2. The mating holes are composed of an upper semicircular hole 62 and a lower semicircular hole 32 forming a circular hole structure. The upper semicircular hole 62 is located at the bottom of the mating block 6, and the lower semicircular hole 32 is located at the top of the support 3, corresponding to the position of the upper semicircular hole 62. Example 2

[0018] This embodiment is based on Embodiment 1. To prevent damage to the aircraft main beam during assembly and docking, two anti-collision blocks 4 are provided. The two anti-collision blocks 4 are fitted into the two pins 2 above the receiving cavity in a facing state and can move left and right along the pins 2. One anti-collision block 4 can contact and connect with the mating block 6 and support 3 on one side of the receiving cavity, and the other anti-collision block 4 can contact and connect with the mating block 6 and support 3 on the other side of the receiving cavity. By using the two anti-collision blocks 4 fitted on the pins 2, and through the contact and connection between the anti-collision blocks 4 and the mating block 6 and support 3, the direct contact between the aircraft main beam and the mating block 6 and support 3 can be avoided. This not only prevents damage to the aircraft main beam during docking and assembly, but also protects the mating block 6 and support 3, thereby increasing the service life of the docking device and achieving the goal of reducing manufacturing costs. Example 3

[0019] like Figure 4 As shown in the figure, this embodiment provides a docking method for the docking device that accurately improves the docking of intersections, the docking method including the following steps: S1. First, set the base 1 on the docking equipment for assembling the main beam of the aircraft, then place the mating block 6 on the support 3 in the base 1, and finally connect the mating block 6 and the support 3 with the step pin 5. S2. Using the pin 2 to pass through the mating hole on one side of the receiving cavity, first place the anti-collision block 4 on the pin 2, then pass the pin 2 through the intersection hole in the aircraft main beam, then place another anti-collision block 4 on the pin 2, then pass the pin 2 through the mating hole on the other side of the receiving cavity, and finally fix the pin 2, thereby realizing the docking connection of the aircraft main beam. The two anti-collision blocks 4 placed on the pin 2 can prevent the aircraft main beam from being damaged. S3. The step pin 5 is fixedly connected by the connecting nut 7 to prevent relative movement between the mating block 6 and the support 3, thereby realizing the mating connection of the intersection hole of the main beam of the aircraft.

[0020] The present invention employs a docking device and method for accurately improving the alignment of the intersecting points. Two spaced supports 3 are provided on the base 1, forming a receiving cavity between the two supports 3 and the base 1. A mating block 6, detachably connected to each support 3, is provided on the support 3. The base 1 is first adjusted to the accurate position, and then the receiving cavity formed between the support 3 and the base 1 is used as the installation position. Under the action of the pin 2, the intersecting holes of the aircraft main beam can be aligned and assembled. Natural assembly can be achieved while ensuring accuracy. Simultaneously, the anti-collision block 4, fitted onto the pin 2, prevents damage to the aircraft main beam during the alignment adjustment process, thus protecting the main beam. The mating block 6 is connected to the support 3 via a stepped pin 5, facilitating installation and disassembly.

[0021] In summary, the docking device and docking method described in this invention not only enable convenient and quick installation and disassembly, but also allow for rapid and accurate position adjustment, thereby improving the installation accuracy of components or finished products.
