Description

Technical Field

[0001] The utility model relates to the technical field of parts spray painting, in particular to a parts spray painting device for aviation manufacturing. Background Art

[0002] A paint spraying device, also known as a high-pressure paint spraying device, is a device that delivers paint to a spraying device with a pressure greater than 1.5MPa. The working principle of the device is mainly to atomize the paint and evenly apply it to the surface of the object through pneumatic or electric power.

[0003] For example, an automatic painting device for processing aircraft seat accessories (Announcement No.: CN215612537U) includes a base, the upper part of the base is fixedly connected to a driving chamber, the lower middle part of the driving chamber is fixedly connected to a motor, the upper driving end of the motor is fixedly connected to a driving rod, the upper end of the driving rod is fixedly connected to the lower middle part of the U-shaped plate, the left and right middle parts of the U-shaped plate are fixedly connected to hydraulic rods, and the driving ends of the hydraulic rods are fixedly connected to clamps. In the utility model, by rotating the aircraft seat parts in the painting chamber and then painting their surfaces, the surfaces can be painted evenly, and hot air is blown into the painting chamber by a hot air blower to dry the paint on the surface of the aircraft seat parts, ensuring that no drip marks will appear on the surface of the aircraft seat parts after painting is completed, which is worthy of vigorous promotion.
