Laser micro-texture process method for strengthening of conical face of rotary excavating tooth

The invention relates to a laser micro-texture process method for strengthening of a conical face of a rotary excavating tooth. The method comprises the following specific steps that S1, the surface is cleaned, wherein the surface of the conical face of the rotary excavating tooth is subjected to oil removal and rust removal under the room temperature and is cleaned through ethyl alcohol; S2, the speed is designed, wherein a rotary excavating tooth seat cleaned in the S1 is fixed to a laser machining tool, the rotary excavating tooth seat is driven by a chunk to rotate, and the rotation of the chunk and the feed motion of a laser head X linear shaft are matched; S3, the laser irradiation is conducted, wherein micro pits are formed in the surface of the rotary excavating tooth fixed in the S2 through a laser; S4, natural cooling is conducted, wherein pulse laser beams are closed, after the beams stop working, cooling is conducted, and the cooling process is the natural cooling; and S5, forming is conducted, wh
