The invention relates to the technical field of rotating motor shell machining, and discloses rotating motor shell end surface leveling equipment and method. The equipment comprises a machine body, wherein the bottom of the machine body is fixedly connected with a fixed case through a bolt, the bottom of the inner side of the fixed case is fixedly connected with a transverse drive adjusting mechanism, the top of the transverse drive adjusting mechanism is connected with a cone connecting seat, the top of the cone connecting seat is fixedly connected with a low-speed motor, an output shaft of the low-speed motor is fixedly connected with a torque rotating shaft through a coupler, and a transverse movable groove is formed in the middle of the top of the machine body. According to the rotating motor shell end surface leveling equipment and method, the machine body, the transverse drive adjusting mechanism, the low-speed motor, a buffer connecting mechanism, a positioning base, a radial adjusting mechanism, a transverse positioning mechanism, an electric lifting rod, a grinding motor, a control panel and a leveling grinding disc are mutually matched, so that the soft contact between the leveling grinding disc and a rotating motor shell is realized, the stability of the running fit between the mechanisms is guaranteed, and the processing of the end face of the rotating motor shell is facilitated.
