Description

Technical Field

[0001] The utility model relates to the technical field of aviation equipment, and in particular to an assembly tool for an eVTOL aircraft cabin door. Background Art

[0002] The cabin door of the eVTOL aircraft provides a passage for passengers to get on and off the aircraft. While meeting the needs of opening and closing, it also needs to have certain sealing requirements. However, as an aircraft, the eVTOL aircraft needs to ensure the accuracy of the shape of the external aerodynamic surface, and the gap with the fuselage should not be too large. During manufacturing and assembly, high dimensional accuracy is required. The cabin door of the eVTOL aircraft is generally divided into an inner panel, an outer panel, and an internal lock. It is installed on the fuselage structure through a hinge. In order to be able to rotate, the coaxiality requirements of the hinge shaft are also high. During assembly, tooling is required to ensure the relevant installation accuracy and the connection between the inner and outer panels. Existing tooling, such as the Chinese utility model patent "A cockpit door inner panel assembly tool" with application number 202320457660.7, uses complex positioning plates, support frames, clamping mechanisms, etc. for the assembly of only one inner panel, lacks conformal fixtures, has high tooling costs, and the appearance accuracy of the assembled cabin door inner panel is not high.

In the description of the utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.

[0022] Example

[0023] like Figure 1 As shown, the utility model provides an eVTOL aircraft cabin door assembly tool, which completes the assembly of the eVTOL aircraft cabin door 2, ensures the shape accuracy, size, and hinge axis accuracy of the eVTOL aircraft, and the eVTOL aircraft cabin door 2 is fixed in a horizontal position during assembly, so that when the inner panel and the outer panel are glued, the structural glue will not slip away due to gravity, thereby ensuring the quality of the bonding and meeting the use function of the eVTOL aircraft cabin door 2 after assembly.

[0024] like Figure 2 As shown, the assembly tool 1 includes a support frame 11, a hinge positioner 12, an upper pallet assembly 13, and a lower pallet assembly 14. Multiple groups of upper pallet assemblies 13 and lower pallet assemblies 14 are installed on the support frame 11. Each group of upper pallet assemblies 23 and lower pallet assemblies 14 are distributed up and down. Multiple hinge positioners 12 are installed on one side above the support frame 11; the support frame 11 is a frame structure, welded from steel profiles, and is the basis of the entire tool. The working surface of the assembly and the eVTOL aircraft cabin door 2 is raised to a height that is convenient for workers to operate, which is 1.2 meters in this example. The hinge positioner 12 is connected to the hinge of the eVTOL aircraft cabin door 2 to ensure the accuracy of the hinge and meet the rotation requirements of the hinge around the axis. The lower pallet assembly 14 serves as a support inside the eVTOL aircraft cabin door 2 to position and limit the inner panel to ensure the accuracy of the inner panel. The upper clamping plate assembly 13, in addition to ensuring the accuracy of the outer panel of the cabin door 2 of the eVTOL aircraft, also applies a certain pressure to the outer panel and applies it to the structural adhesive between the inner panel and the outer panel to meet the requirements of structural adhesive curing.

[0025] like Figure 3As shown, a lower limit block 141 is provided on the lower card plate assembly 14, and the lower limit block 141 contacts the inner panel of the cabin door 2 of the eVTOL aircraft for limiting. The shape of the contact position of the lower limit block 141 is processed according to the theoretical shape. The lower limit block 141 is machined from aluminum alloy and installed on the lower card plate assembly 14 by bolts. The lower limit block 141 on each lower card plate assembly 14 is processed according to the shape of the inner panel here. The lower limit block 141 is installed on each lower card plate assembly 14 and is arranged around the inner panel of the cabin door 2 of the eVTOL aircraft. This figure shows only one place.

[0026] like Figure 4 As shown, multiple hinge locators 12 are connected to the support frame 11 by bolts, and the mounting holes of the hinge locators 12 and the hinge holes of the eVTOL aircraft cabin door 2 are positioned by pins to ensure that the multiple hinge holes are on the same straight line. The hinge locators 12 are made of steel with high hardness to ensure the wear resistance of the mounting holes of the hinge locators 12, and to ensure that they will not wear out after multiple assemblies and maintain high precision. This figure only shows one place.

[0027] like Figure 5 As shown, the upper cardboard assembly 13 includes an upper connecting joint 131, an upper cardboard body 132, an upper top block 133, and an upper limit block 134. Both ends of the upper cardboard body 132 are connected to the upper connecting joints 131, and the upper top block 133 and the upper limit block 134 are installed on the upper cardboard body 132; the upper cardboard body 132 is the basic structure, and other structures are connected to the upper cardboard body 132. The upper connecting joint 131 is connected to the support frame 11, and the other end is connected to the upper cardboard body 132. Both ends are connected to the upper cardboard body 132 by a pin shaft, so that they can rotate around the pin shaft. When the inner panel of the cabin door of the eVTOL aircraft is positioned and installed on the assembly tool, one end of the upper cardboard body 132 is opened and rotated around the pin shaft. When the outer panel is installed, the upper cardboard assembly 13 is closed to achieve the assembly requirements. The upper limit block 134 is limited to the upper boundary to ensure that the upper boundary is not too long, causing interference with the surrounding structure when the assembled eVTOL aircraft cabin door rotates around the hinge axis. The upper ejector block 133 is used in conjunction with the lower ejector pin 144 of the lower card assembly 14 to pressurize the bonding area around the cabin door window to meet the pressure requirement when the structural adhesive is cured. The upper card body 132 and the cabin door outer panel are processed according to the theoretical shape to ensure the accuracy of the shape of the equipment area and the vicinity, and at the same time play a role in applying pressure to provide pressure for the curing of the structural adhesive.

[0028] like Figure 6As shown, the lower card assembly 14 includes a lower limit block 141, a lower connection joint 142, a lower card body 143, and a lower ejector pin 144. The lower card body 143 is connected to the lower connection joint 142 at both ends, and the lower card body 143 is installed with the lower limit block 141 and the lower ejector pin 144; the lower limit block 141 limits the inner panel of the cabin door of the eVTOL aircraft around to ensure the accurate positioning of the inner panel of the cabin door. The lower connection joint 142 is connected to the support frame 11 at both ends, and is connected to the lower card body 143 by a fixed connection, and does not need to rotate relative to the lower card body 143. The lower ejector pin 144 is used together with the upper ejector block 133 to pressurize the bonding area around the cabin door window to meet the pressurization requirements when the structural adhesive is cured. The contact position between the lower card body 143 and the cabin door inner panel is processed according to the theoretical shape of the inner panel, and the inner panel is supported to ensure the accurate shape of the inner panel.
