Machine tool leveling adjustment device

A leveling adjustment device attached to a machine tool with a plurality of supporting foot portions being adjusted manually to change a height, comprising:

• a sensing module configured to sense the machine tool for one inclined extent in a longitudinal direction and an another inclined extent in a lateral direction and then generate a sensed data;
• and
• a microcontroller unit electrically connected with the sensing module and receiving the sensed data, the microcontroller unit providing a graphical operation interface having a frame pattern, representing an outline of a bottom of the machine tool, with a coordinate system, the graphical operation interface providing a plurality of first blanks to be filled with a data about a length and a width of the bottom of the machine tool and a plurality of second blanks to be filled with a data about a quantity of the supporting foot portions and a data about a coordinate corresponding to each of the supporting foot portions, the graphical operation interface generating, based on the data in the second blanks, a plurality of third blanks within the frame pattern to represent a location of each of the supporting foot portions and a plurality of fourth blanks corresponding to the third blanks, the microcontroller unit calculating an adjustment sequence and an adjustment value corresponding to each of the supporting foot portions based on the data in the first blanks and the second blanks in conjunction with the sensed data and then displaying in the fourth blanks.
