The utility model discloses a breechblock part upper end inclined plane inclination angle measuring device which comprises a measuring body, two supporting guide rails, a screw and a positioning pin. The measuring body is a cubic supporting frame with an opening in one surface, and two positioning ribs are arranged on the inner surface of a supporting surface on the upper side of the opening surface of the measuring body; two supporting guide rails are fixed to the inner surface of a supporting face on the lower side of the open face of the measuring body through screws, and inclined faces matched with the inclined angle of the inclined face of the lower end of the wedge type breechblock part are machined on the upper surfaces of the two supporting guide rails. The distance between the lower surfaces of the two positioning ribs and the upper surfaces of the two supporting guide rails is matched with the distance between the upper end plane and the lower end inclined plane of the wedge type breechblock part; a
