Description

Technical Field

[0001] The invention relates to the technical field of paint spraying equipment, in particular to a paint spraying device for automobile wheel hubs. Background Art

[0002] The car wheel hub is an important component of the car. It plays the role of supporting the weight of the car body and has a very important impact on the car's energy saving, environmental protection, safety and operability.

[0003] The automobile wheel hub is provided with a support frame for supporting the wheel hub, such as Figure 2 There is a recessed platform under the support frame. Now we need to apply colored paint on the recessed platform, but the support frame is above the convex platform, which makes it inconvenient to spray paint because it will be blocked by the support frame. Summary of the invention
