Abstract

The invention discloses an automobile sheet metal part coating device and method, and relates to the technical field of sheet metal treatment. The device is composed of a magnetic attraction rubber plate, a partition vertical piece, a positioning hanging block and a water collecting groove. The magnetic back plate on one side of the magnetic rubber plate can enable the device to be attracted to the sheet metal part, and operation is convenient. The multiple exposure openings with the gradually-increased diameters are used for being matched with rust of different sizes, the rust range can be observed conveniently through the positioning observation notches in the annular side conical ring face, and it is ensured that the rust remover acts on the rust area accurately. The vertical blocking piece plays a role in separation and protection, and the positioning hanging block is used for being matched with a liquid spraying positioning hanging piece. The water collecting tank is located below the exposure opening and used for collecting liquid generated by rust removal. A liquid spraying mounting sleeve, an extending hanging rod and a hanging head of the liquid spraying positioning hanging piece are matched with a sprayer of the liquid sprayer, and it is guaranteed that the rust remover is accurately sprayed to the rust center. According to the rust removal device, rust on the surface of the sheet metal part is efficiently removed, excessive damage or other adverse effects on the surface of the sheet metal part are avoided, and the treatment cost is reduced.
