Description

Technical Field

[0001] The utility model relates to the technical field of in-situ repair of pipe joints, in particular to conical surface finishing processing equipment for non-detachable aviation pipe joints. Background Art

[0002] Aircraft pipe joints are connected to aviation flared conduits. Flared conduits are mainly used in aircraft hydraulic systems, fuel systems, air pressure systems, etc. They are the main carriers for gas and liquid transportation on aircraft. As the conduits are often accompanied by external environments such as vibration, bending, and impact, the conical surface of the pipe joints is often damaged.

[0003] The existing technology for repairing the conical surface of this type of stainless steel pipe joint adopts the method of separating the parts, fixing them on a machine tool and repairing them. However, some non-detachable pipe joints still require manual entry into a narrow environment and manual processing and repair, which makes it difficult to meet the processing requirements and the tool is prone to chipping, causing secondary damage to the end face of the pipe joint.

[0004] Therefore, we proposed a non-detachable aviation pipe joint conical surface finishing equipment to solve the problem. Utility Model Content
