Deburring mechanism

The utility model belongs to the technical field of machining, and particularly relates to a deburring mechanism which comprises a workbench, a fixing unit, a buffering unit and a deburring unit. The fixing unit is arranged on the workbench and is used for fixing an end socket; the buffering unit comprises a supporting seat and a buffering assembly, the supporting seat is arranged on the workbench, and the buffering assembly is arranged on the supporting seat; the deburring unit is arranged at the bottom of the buffering assembly and located above the fixing unit. When burrs of the end socket are removed, the buffer assembly can drive the burr unit to move in the y-axis direction, and the burr unit moves in the y-axis direction to get close to and make contact with the end socket, polish the end socket and remove the burrs on the end socket, so that the working efficiency of removing the burrs of the end socket is effectively improved; the buffer assembly can buffer the pressure generated when the burr unit g
