Abstract:
A wheel spraying protection device is composed of a hollow mounting rack, an electric cylinder, a tray, an electromagnetic chuck, a sleeve, a piston, a soft rubber cover, a support column, an end cover, high temperature resistant plastic protective plugs, springs and iron posts. The device can play a role in protecting during a wheel spraying process, and solves the problem that a flange face, a center hole and bolt hole conical surfaces are adhered with paint. The device has the characteristics of advanced process, easiness in manufacturing, simple structure, strong function and the like.

Claim (Index 1):
A wheel spraying protection device, being composed of a hollow mounting rack, an electric cylinder, a tray, an electromagnetic chuck, a sleeve, a piston, a soft rubber cover, a support column, an end cover, high temperature resistant plastic protective plugs, springs and iron posts,\n wherein the tray is mounted above the hollow mounting rack, the electromagnetic chuck is embedded into the tray, the electric cylinder is fixed inside the hollow mounting rack, an output end of the electric cylinder is connected with the piston, the piston is matched with wall an inner wall of the sleeve, an outer wall of the sleeve is fit with the hollow mounting rack, the tray and the electromagnetic chuck, an upper end face of the sleeve is connected with the electromagnetic chuck via screws, a lower end of the support column is fixed on the sleeve, an upper end of the support column is fixed on the end cover, a space formed by the end cover and the sleeve is sealed by the soft rubber cover, and a medium in the sleeve is air; when the electric cylinder drives the piston to move up, the space formed by the end cover and the sleeve is reduced, the soft rubber cover is expanded by air extrusion, and the expanded soft rubber cover is fit with an inner wall of a center hole of a wheel to protect the center hole; when the electromagnetic chuck is powered on, the iron posts are fit with the electromagnetic chuck, the wheel is fixed on the electromagnetic chuck, not only is a flange face of the wheel completely fitted with a plane of the electromagnetic chuck, but also conical surfaces of the high temperature resistant plastic protective plugs are fit with bolt hole conical surfaces, so that the flange face and the bolt hole conical surfaces are protected.
