[0002] As we all know, thin-walled aviation aluminum alloy tube is a tubular component made of lightweight, high-strength aluminum alloy material. It has a small wall thickness and a large inner diameter, is light in weight and high in strength, and is commonly used in aerospace, automobile, shipbuilding and other fields. Thin-walled aviation aluminum alloy tube has excellent corrosion resistance and can be used for a long time in harsh environments without damage. Thin-walled aviation aluminum alloy tube usually needs to be processed by drilling holes to meet the connection requirements of different system pipes and accessories. The drilling device is a mechanical equipment specially used for drilling holes in thin-walled pipes.

[0003] However, traditional thin-wall aviation aluminum alloy tube hole opening devices are usually designed for aluminum alloy tubes of specific sizes and cannot be applied to aluminum alloy tubes of various sizes. This limits its scope of application and requires additional tools and devices to handle pipes of different sizes. Therefore, technical improvements are urgently needed. Utility Model Content
