Automatic paint spraying device for whole surface of steel wheel

The invention relates to the technical field of steel wheel manufacturing, in particular to an automatic paint spraying device for the whole surface of a steel wheel. The device at least comprises a ground rolling chain, a supporting rod and a rotating mechanism, the supporting rod is vertically and detachably installed on the ground rolling chain, the ground rolling chain drives the supporting rod to operate horizontally, the rotating mechanism is located in a paint spraying chamber and used for driving the supporting rod to rotate, and a positioning clamp is arranged at the end of the supporting rod and used for clamping the supporting rod. The positioning fixture is used for positioning and mounting a wheel to be sprayed; the supporting rod is detachably installed on the ground rolling chain in a buckling mode. The supporting rod is installed on the ground rolling chain in a rapid buckling mode, when the supporting rod or the clamp needs to be replaced, the supporting rod and the clamp can be disassembled
