Description

Technical Field

[0001] The utility model relates to the field of spraying equipment, in particular to a spraying device for producing bicycle frames. Background Art

[0002] There is a processing step in the bicycle production process to paint the frame. By painting the frame, it not only has the ability to resist corrosion, but also makes the frame style more diverse.

[0003] In an existing rotary table type spraying device for frame production, when performing frame painting production, the frame to be painted needs to be inserted and placed on the insertion mechanism first, and then the frame is driven to rotate by the rotating mechanism, and the frame rotates. At this time, the automatic painting mechanism continues to spray paint, and the surface of the frame is painted by such rotary spraying. However, the insertion mechanism of the existing device of this type is only a smooth column structure. When the frame is inserted and placed, the inner wall diameter of the empty tube of the frame needs to exceed the diameter of the column. In this way, coupled with the surface structure characteristics of the smooth column, the frame will shake during the rotation process, which is not only inconvenient for painting the entire frame, but also easy to cause the frame to fall, causing damage to the frame.
