Positioning processing tool and positioning processing method for seven-star hole in conical surface

The invention discloses a positioning processing tool and a positioning processing method for a seven-star hole in a conical surface, and solves the positioning problem on processing the seven-star hole in the conical surface through a horizontal processing center. The positioning processing tool for the seven-star hole in the conical surface comprises a conical surface workpiece (11) to be processed, a conical surface-shaped drill jig upper mold plate (1) and a conical surface-shaped drill jig lower mold plate (2), wherein an upper mold plate conical surface seven-star hole and a lower mold plate conical surface seven-star hole are processed in the conical surface-shaped drill jig upper mold plate and the conical surface-shaped drill jig lower mold plate through a numerical control five-axis linkage processing center; a central axis of each hole of the upper mold plate conical surface seven-star hole (12) is perpendicular to a generating line of the curved surface on which the hole islocated; a central axis
