1. A device for assist in blade detection, comprising
a supporting frame,
wherein said supporting frame is disposed on a surface of a blade; said supporting frame comprises a plurality of aluminum (Al) extruded frames and a plurality of adjustment rotating pads; an Al extruded connector is obtained to connect each adjacent two of said Al extruded frames; each of said adjustment rotating pads is disposed on one of said Al extruded frames through a pad fixing plate; and each of said adjustment rotating pads has a thread and a bottom to obtain a plurality of adjustment operations, wherein each of said adjustment rotating pads is adjusted based on a curvature of a surface of said blade to have said bottom of each of said adjustment rotating pads be in close contact with said surface of said blade and accordingly adjust a height of said one of said Al extruded frames above said supporting frame;
a linear track,
wherein said linear track comprises a plurality of sub-tracks and a plurality of sliders; a track connector is obtained to connect each adjacent two of said sub-tracks; each of said sub-tracks is in a state selected from a group consisting of a state of being disposed in a fixed position, a state of moving longitudinally, and a state of moving laterally; and each of said sliders moves linearly on one of said sub-tracks to assist maintaining a detector on said surface of said blade to operate a linear detection selected from a group consisting of a longitudinal linear detection and a lateral linear detection without deviating from straight-moving on track; and
a fixture,
wherein said fixture is fixed to one of said sliders with a bolt to freely move said fixture to a position to operate detection of said blade; said fixture comprises a bearing seat, a bearing connector, a sliding rod, a joint bearing, a chuck, and said detector; and said fixture has three freedoms, comprising swivel-pair freedom, sliding-pair freedom, and ball-facing freedom, to have said detector be in contact with said surface of said blade to operate said detection of said blade.
