Machine base footing machining device

The invention discloses a machine base footing machining device which comprises a base, a machine base, a machining device and a positioning device. The pressure plate is arranged at the top of the base in a suspended manner, and moves towards the base to be used for pressing the machine base onto the base; the ejector rods are rotationally and symmetrically arranged on the side of the base, and the ejector rods can rotate towards the machine base to abut against and press the bottom feet of the machine base to limit axial rotation of the machine base. By arranging the positioning mechanism, the two ejector rods abut against the two bottom feet respectively, so that the two bottom feet are kept in a flush state, and meanwhile the situation that the machine base rotates due to transverse force generated when a machining tool machines the bottom feet, and the two bottom feet are broken due to vibration in the using process due to the fact that the two bottom feet are not flat after being machined is effectively
