Medium-and-high curve, current-voltage curve (CVC) and arbitrary curve grinding device for roller grinder

The invention discloses a medium-and-high curve, current-voltage curve (CVC) and arbitrary curve grinding device for a roller grinder. The device is arranged in a grinding frame; a grinding wheel (1) is arranged on the front part of a shell (2) on the grinding frame; a rolling wheel (12) is connected with a rolling wheel seat (13) through a rotary shaft (14), and is fixed in the shell (2) on the grinding frame; a bearing seat (8), a linear rolling guide rail (9) and a support (10) are arranged on the top surface of a shell (11) below the grinding frame respectively; and a motor (6) is used for driving a ball screw (3) to rotate through a speed reducer (7) and driving a sliding oblique block (4) to slide back and forth along the linear rolling guide rail (9). Through the movement of the sliding oblique block (4), the shell (2) on the grinding frame is swung up and down around a point O, so that the grinding wheel (1) is driven forwards or is retreated, and the requirement that a medium-and-high ...
