A device for measuring the height difference of a stand column of a numerical control machine tool comprises a pair of measuring assemblies and a connecting pipe, and each measuring assembly comprises a barrel containing a flowing medium and used for being placed on a guide rail face of the stand column of the machine tool; the dial indicator is arranged above the cylinder body; the buoy is arranged in the cylinder and connected with the dial indicator, and the dial indicator measures the liquid level height change of the flowing medium according to the height change of the buoy; the bottoms of the cylinders of the pair of measuring assemblies are communicated through a connecting pipe. According to the device for measuring the height difference of the stand column of the numerical control machine tool, the height difference between the guide rails of the stand column of the machine tool is obtained through the height change of the liquid level of the flowing medium in the two communicated cylinders, manual o
