The present invention relates to a belt grinder for grinding a bead at a welded part and, more particularly, to a device for adjusting the height of a contact wheel which can perform surface cutting by being contact with a welding bead. The belt grinder for grinding a bead at a welded part can grind a bead generated by welding work. The belt grinder for grinding a bead comprises: a front side driving unit which collects ground chips while moving along a welding bead formed in a straight line or a curved line; a back side driving unit which can regulate the direction in order to drive along a face where a welding bead is formed, and can regulate the cutting height of the welding bead; and a grinding module unit which is installed in between the front side driving unit and the back side driving unit, and grinds the welding bead by the rotation of a belt grinder while driving the welding bead. Therefore, the belt grinder for grinding a bead at a welded part can perform grinding work while properly regulating the height of the bead at the welded part by installing a height regulating unit which vertically reciprocates the grinding module unit for grinding the bead at the welded part, thereby properly reinforcing according to the welded part. |
