The three positioning assemblies 61 and the three axial pressure sensors 7 are arranged, the three positioning assemblies 61 can form a plane, the plane is parallel to a beam rotating plane, whether the beam rotating plane is parallel to a flange surface to be machined of a blade root can be judged through the consistency of the pressures sensed by the three axial pressure sensors 7, and the beam rotating plane is a plane where the milling cutter is rotated and machined. At this time, the machining operation can be started directly, or the next adjustment can be performed according to the machining requirement.
According to different milling machine settings and processing requirements, the plane formed by the three positioning components 61 and the beam rotating plane are located on the same plane, and the positioning components 61 can be processed when being close to the blade root flange surface. Or the milling machine can be driven by the motor of the fine adjustment component 51 to move towards the outward direction of the axial direction of the inner circle of the blade root, and the scanned blade is processed. Because the positioning support leg 52 is already tensioned on the inner surface of the blade root, the motor drives the positioning support leg 52 and the lifting tensioning part 5 to generate axial relative motion along the guide rail, and one end of the lifting tensioning part 5 is fixed on one side of the center of the milling machine, so that the whole milling machine is driven to move towards the axial direction of the inner circle of the blade root outwards.
