The device comprises a supporting frame, a linear track, and a fixture. The supporting frame comprises a plurality of aluminum extruded bodies with connectors thereof and a plurality of rotating adjusting pads with fixing plates thereof; the linear track comprises a plurality of tracks with connectors thereof and a plurality of sliders; and the fixture comprises a bearing holder part, a bearing connector, a sliding rod, a joint bearer with a connector thereof, a chuck, and a detector. On detecting a blade, the present invention helps the detector to be maintained on the blade surface for detection in horizontal and vertical directions without deviating from track; and the detector is in contact with the blade surface to move precisely and regularly without missing or repeating detection areas. Thus, the area is detected completely with time saved and accuracy improved. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The device according to claim 1, wherein said supporting frame comprises a plurality of said Al extruded frames with each adjacent two thereof connected via said Al extruded connector to adjust a size of said supporting frame. ### Claim 3 (depends on 1) The device according to claim 1, wherein a distance between two of said aluminum extruded frame at any different positions in said support frame is adjustable. ### Claim 4 (depends on 1) The device according to claim 1, wherein said adjustment operations comprises an operation of adjusting positions and numbers of said adjustment rotating pads; an operation of self-adjusting a distance between said bottom of each of said adjustment rotating pads and each of said aluminum extruded frame; and an operation of adjusting an angle between said bottom and said thread of each of said adjustment rotating pads. ### Claim 5 (depends on 1) The device according to claim 1, wherein said linear track comprises a plurality of said sub-tracks with each adjacent two thereof connected via said track connector to adjust a length of said linear track. ### Claim 6 (depends on 1) The device according to claim 1, wherein each of said sub-tracks has a plurality of holes evenly disposed and equally spaced that, with one of said holes being used to connect to said supporting frame, a connecting position of said linear track is adjusted. ### Claim 7 (depends on 1) The device according to claim 1, wherein each of said sub-tracks is selected from a group consisting of a longitudinal sub-track and a lateral sub-track. ### Claim 8 (depends on 1) The device according to claim 1, wherein said bearing seat is fixed on said one of said sliders with said bolt; said bearing connector is connected to said bearing seat with said swivel-pair freedom obtained; said sliding rod passes through said bearing connector with said sliding-pair freedom obtained; an end of said joint bearing is fixed to a bottom end of said sliding rod with a nut; and said chuck is fixed to another end of said joint bearing with a bolt with said detector fixed to said chuck to have said detector and said chuck being face-turned to said sliding rod with said ball-facing freedom obtained. ### Claim 9 (depends on 1) The device according to claim 1, wherein said blade has a size adjustable and said surface of said blade has said curvature adjustable.
