The invention provides a numerical control rocker arm drilling machine, belonging to the field of processing machinery. The technical scheme of the invention is as follows: the invention comprises a stand column, a rocker arm which is installed on the stand column, and a main shaft box which is installed on the rocker arm and a base which is fixedly connected with the bottom part of the stand column; a numerical control drive assembly is arranged between the main shaft box and the rocker arm, and the main shaft box moves along the rocker arm in the numerical drive assembly; the main shaft is provided with the numerical control drive assembly for main shaft speed change and feed; the rocker arm is provided with the numerical control drive assembly for the swinging of the rocker arm. The technical scheme can be realized by reforming current rocker arm drilling machine, and can be realized so long as adopting the structure of inner columns and outer columns; therefore, a high-quality numerical control device can be built by spending a small amount of expenses, thus the promotional value thereof can be imaginable.
