AI Technical Summary
The existing method of spraying color rings on oil casings relies on manual operation, which makes it difficult to guarantee the quality of the spraying and is inefficient.
Design a color ring spraying fixture for oil casing, including a coupling body and a limiting component. It matches the oil casing through the casing channel. The spraying window extends circumferentially along the coupling body. The limiting component restricts the insertion depth of the fixture. During spraying, paint is sprayed directly onto the spraying window.
It achieves rapid and accurate color ring spraying for oil casing, simplifies the operation process, and improves spraying quality and efficiency.
