Composite material-metal laminated irregular-shape thin-wall cabin section machining tool

The invention relates to a machining tool for a composite material-metal laminated irregular-shaped thin-wall cabin section, belongs to the technical field of part machining, and solves the problems that an existing irregular-shaped part is unstable in clamping and large in machining vibration, and the machining precision is affected. A machining tool for a composite material-metal laminated irregular-shaped thin-wall cabin section comprises an adjusting assembly, a clamping ring, a pressing frame, a pull rod and a flange plate. One end of the clamping ring is fixedly and movably connected to one side of the adjusting assembly, and the other end of the clamping ring is detachably or fixedly connected to the other side of the adjusting assembly. The pressing frame is arranged at one end of the adjusting assembly and used for pressing and fixing the flange plate at one end. The number of the flange plates is at least two, and the lower ends of the flange plates can be supported above one end of the adjusting as
