Description

Positioning tool for assisting installation of lining plate on side wall inside fuselage Technical Field The utility model relates to the technical field of aircraft maintenance, in particular to a positioning tool for assisting a lining plate to be installed on the side wall of the interior of a fuselage. Background In the process of converting a passenger aircraft into a cargo aircraft, lining plates are required to be installed on two sides of the interior (namely, a main cargo compartment) of the aircraft body, and the lining plates are fixed by lining plate supports. These lining brackets are mounted on the former and the mounting position is determined by their relative dimensions in height to the seat rail. In a passenger-to-cargo aircraft, the lining plate supports need to be positioned on more than hundred of the bulkhead frames on the left side and the right side of the passenger-to-cargo aircraft, and about 6 lining plate supports need to be installed on each bulkhead frame. Positioning each liner support on each former would be a very tedious and time consuming task. A tool is therefore needed to quickly position these liner supports in order to improve efficiency. Disclosure of utility model The utility model aims to provide a positioning tool for assisting in installing lining plates on the side wall of the interior of a machine body, which can simultaneously position a plurality of lining plate brackets on the side wall of the interior of the machine body. In order to solve the technical problems, the utility model adopts the following scheme: The utility model provides a location frock for assisting inside lateral wall installation welt of fuselage, is including being used for the bottom plate fixed with the seat rail, is equipped with on the bottom plate and is used for supplying the bolt to pass the mounting hole of fixing the bottom plate on the seat rail, is equipped with on the bottom plate and is used for the riser that sets up perpendicularly with the seat rail, is equipped with crooked radian and fuselage inside wall assorted cambered surface on the riser, has at least three welt support along cambered surface extending direction distribution on the cambered surface. Because the fuselage is equipped with two sets of seat rails that extend along fuselage length direction at least in, the mounting hole is equipped with two at least sets of, and the distance between every two sets of adjacent mounting holes equals the distance between every two sets of adjacent seat rails. The vertical plate type lining board frame has the advantages that according to the structural characteristics of the aircraft body, the cross section inside the aircraft body is identical in shape and size except for the aircraft nose and the aircraft position, namely, the bending degree and the length of each bulkhead are identical, the positions of the lining board supports with the same horizontal height on each bulkhead are identical based on the structural characteristics, the lining board supports can be fixed on the vertical plates through the arrangement of the vertical plates, and therefore, the lining board supports on the vertical plates are all at the same height no matter the vertical plates move to any position in the aircraft body along the seat rail, and therefore, the lining board supports can be positioned quickly, and the working efficiency of lining board installation is improved effectively. Further, the liner support includes a connection surface for connection to the riser and a locating surface for locating the liner on the interior side wall of the fuselage. The connecting surface is welded with the vertical plate. Further, a through hole for the bolt to pass through is formed in the positioning surface. The lining plate can be temporarily positioned on the side wall of the machine body through the arrangement of the through holes, and after the lining plate is installed on the side wall of the machine body, the bolts on the through holes are taken down. Further, the connecting surface is arranged in parallel with the vertical plate, and the positioning surface is arranged perpendicular to the connecting surface. The function is that each positioning surface can be arranged in close parallel with the adjacent inner wall of the machine body through the arrangement of the spatial relationship between the connecting surface, the positioning surface and the vertical plate. Further, six lining board brackets are arranged. Further, at least two reinforcing transverse ribs which are arranged in parallel with the bottom plate are arranged on the vertical plate. The structure has the effect that the structural strength of the vertical plate in the horizontal direction can be enhanced through the arrangement of the reinforcing transverse ribs. Further, at least two reinforcing vertical ribs which are perpendicular to the bottom plate are arranged on the vertical plate. The vertical plate structure has
