The invention discloses a cold
rolling mill roller surface treatment device. The device comprises a
grinding box, a
liquid storage cavity is formed in the side wall of the
grinding box, a motor is fixedly arranged on the side wall of the
grinding box, an output shaft of the motor extends into the grinding box, chucks are arranged at the
tail end of an output shaft of the motor and the inner wall,right opposite to the output shaft of the motor, of the grinding box, and reciprocating lead screws are rotationally connected between the inner walls, located above and below the chucks, of the grinding box. According to the device, through the arrangement of a driving mechanism, a liquid pumping mechanism, an elastic film, a through hole and a liquid outlet hole, a grinding ring horizontally moves in a reciprocating manner, and a roller rotates so that the surface of the roller can be stably and evenly ground, and the coaxiality precision and the
surface smoothness of the roller are improved; and cooling liquid can be automatically sprayed for cooling and heat dissipation, the spraying time is fixed, the manual control is not needed, the precision is high, and the cooling liquid can be recycled, so that the environment is protected, and the cost is saved.
