[0002] In the past, when assembling non-ferrous metal pipeline branches on ships, the method of drilling holes in the main pipe first and then assembling the branch pipe welding seat was adopted. However, this method makes the installation accuracy of the branch pipe affected by the positioning and drilling accuracy of the branch pipe drilling. In some high-precision assemblies, it is necessary to assemble the welding seat first and then use a drill bit to insert into the inner hole of the welding seat to drill. However, this method will cause burrs to remain on the inner wall of the main pipe after drilling, which is difficult to remove. Summary of the Invention

This device transmits force to a storage spring via a gear reduction mechanism. The storage spring generates accumulated force and instantly releases torque, causing the turning tool to rotate rapidly to remove burrs. A buffer spring is installed on the tool head connecting rod, causing the tool head to axially oscillate during rotation, thus addressing the technical problem of residual burrs on the inner surface of main pipe drilling sites during non-ferrous metal branch pipe assembly.
