Railway vehicle exterior wall panel mounting method

Abstract

The invention discloses a railway vehicle exterior wall panel mounting method which comprises the following steps: S1, pretreatment, namely grinding, cleaning and drying the vehicle body surface, andcleaning and drying the exterior wall panel surface; S2, positioning, namely scribing, mounting a vertical positioning tool and a transverse positioning tool, and adhering an adjusting shim on the exterior wall panel; S3, pre-assembling, namely pre-assembling the exterior wall panel, checking the gap and flatness between the exterior wall panel and the vehicle body, and positioning the position ofthe exterior wall panel; S4, performing base coat and gluing, namely removing the exterior wall panel, performing base coat operation in an adhesion area of the exterior wall panel and the vehicle body, and gluing; and S5, adhering, fixing, drying and curing. The mounting process is simple and convenient, and the mounting cycle is short. Compared with the traditional metal exterior wall panel, the exterior wall panel disclosed by the invention is convenient to mount. The vertical positioning tool and the transverse positioning tool are adopted during installation, so that the mounting position of the exterior wall panel is accurately controlled, the adhesion is firm, and the assembling accuracy is high.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method for installing an outer wall panel of a rail vehicle. Background technique [0002] At present, when rail vehicles are decorated with exterior wall panels, most of them use aluminum alloy exterior wall panels and adopt welding methods. This is easy to cause damage to the base material. At the same time, high heat input during welding causes stress concentration and reduces fatigue life. There are also a small number of metal exterior wall panels that adopt the method of bonding, which can avoid the above problems, but because no suitable tooling is used, the installation of the metal panels has the problems of heavy weight and inaccurate size and progress control. The invention patent application with the application number CN201610689426.1 discloses a bonding method for the exterior panels of low-floor rail vehicles, including S01, leveling the car body frame: bond...
