Milling tool for plane milling

The invention provides a milling tool for plane milling. The problem that the plane machining precision of an existing milling clamp is hard to guarantee is mainly solved. The milling tool is characterized in that locating blocks (3) are arranged on the left side, the front side and the rear side of the upper end face of a base (1) respectively; three supporting blocks (4) the same in height are evenly distributed on the upper end face of the base (1); the right side of the base (1) is obliquely connected with a press plate (2) through bolts; a sizing block is arranged between the lower portion of the press plate (2) and the base (1); a 15-degree angle inclined rightwards is arranged on the face, in contact with a workpiece, of the upper end of the press plate (2); a floating supporting column (5) is arranged on the upper end face of the base (1); tapered iron (6) is arranged in the position, below the floating supporting column (5), of the base (1); a screw is connected in the tapered iron (6); and a steel ball clamped with a groove in the base (1) is arranged in the position, in the tapered iron (6), of the end in the screw. The milling tool for plane milling has the beneficial effects of being high in plane machining precision and facilitating clamping.
