Angular displacement output angle precision measuring clamp of main paddle collector ring assembly

The utility model belongs to the technical field of helicopter anti-icing and deicing product assembly, and relates to an angular displacement output angle precision measuring clamp of a main paddle collector ring assembly. Comprising a dividing head, a mounting disc, an adjusting screw, an adjusting seat, a pan head, a hexagon head bolt A, a stand column, a rotation stopping clamp, a hexagon head bolt B, a screw, a gradienter, a T-shaped screw, a hexagon nut, a hexagon head bolt C, a stopping piece, a hexagon head bolt D, a bottom plate, a transition disc, an inner hexagon bolt E, a hexagon nut, a flat washer and a positioning pin. By adjusting the gradienter installed on the main propeller collector ring assembly, all output angles of the main propeller collector ring assembly are kept on the same horizontal plane, accurate measurement of the angular displacement output angle precision is achieved, it is ensured that the angular displacement signal precision output by the main propeller collector ring assem
