The invention relates to a quick alignment unit of a numerical control machining datum for irregular-appearance rough materials. A support plate is disposed on a milling fixture, a positioning device is disposed in the lengthwise direction of the support plate, a quick alignment device is disposed at one width-wise end of the support plate, a press plate is disposed at the other width-wise end of the support plate, and the end of the press plate is disposed above the support plate. Both the positioning device and the press plate are movably connected with the milling fixture. The quick alignment device comprises a quick aligner, two cylindrical positioning pins and a plurality of tapered alignment pins. The tapered alignment pins are disposed on the upper bent surface of the quick aligner. Bottom tips of the tapered alignment pins are evenly distributed on an outline, to be machined, of a casting to be machined. Two cylindrical positioning pins are arranged on the lower bent surface of the quick aligner and f
