| description | The invention belongs to the technical field of aeronautical manufacturing and assembling, and particularly relates to a method and a device for accurately drilling and trimming a large-size Z-shaped hyperbolic stringer, which are used for drilling by using a milling fixture and numerical control machining instead of manual lineation milling, the milling clamp comprises a first clamp body for clamping the web face of the Z-shaped profile, and a single-face flat pressing plate is used for clamping the upper bottom face, needing to be milled and drilled, of the profile, so that it is guaranteed that displacement and vibration are avoided during milling; during milling and clamping, the sunken area is used for positioning, the length size deviation caused by the end allowance can be avoided, parts with the same curvature can share the same tool, milling and drilling of the Z-shaped hyperbolic stringer are completed at the same time, and the production cost is reduced; compared with a traditional method, the part |
