Burr removing machine and tooth sweeping mechanism thereof

The utility model discloses a burr removing machine and a tooth sweeping mechanism thereof. The burr removing machine comprises a tooth sweeping station support seat, a rolling brush arranged correspondingly to the tooth sweeping station support seat and a rolling brush drive device which drives the rolling brush to rotate, and further comprises a tooth sweeping clamping device which clamps a work piece before tooth sweeping and loosens the work piece after the tooth sweeping. By adopting the structure, when the work piece is plated on a tooth sweeping station by a transposition mechanism, the tooth sweeping clamping device clamps the work piece, the rolling brush drive device drives the rolling brush to rotate so as to sweep residual burrs generated by the work piece after being processed through a grinding process, the tooth sweeping clamping device fixes the position of the work piece during the tooth sweeping process through a clamping function for the work piece, and the phenomenon that the rolling brush damages the work piece due to movement of the work piece is avoided. After tooth sweeping work is completed, the tooth sweeping clamping device loosens the work piece so as to enable the transposition mechanism of the burr removing machine to conveniently grasp the work piece and transport the work piece to a next station.
