Zusammenfassung:The invention belongs to the technical field of through hole machining processes, and discloses a large side frame precise drilling machining device which comprises a base, a clamp body, a drill jig body, a supporting body and a marking pin. Screws for hoisting are arranged at four corners of the base, and the supporting body is fixed above the base; the clamp body is also fixed above the base; the drill jig body is arranged above the clamp body, the two scribing needles are symmetrically and horizontally arranged on the two sides of the base, and the needle tips of the scribing needles coincide with the center line of the large side frame; the clamp body is used for outputting equal-distance screw pitches to the left side and the right side at the same time and clamping a large side frame. The supporting body is used for vertically supporting, adjusting and fixing the large side frame. According to the drilling device, accurate and convenient drilling can be achieved, and the actual production efficiency of
