The invention discloses a deburring device for a stamped chain baffle blade, and relates to the technical field of machining. The invention aims to solve the problems of a roller method used for current deburring of small stamped parts that time and labor are consumed; a large amount of water and abrasive are consumed; and water material and sewage emission pollutes the environment. The deburringdevice comprises a reversing guide rail mechanism, two guiding groove plates and two abrasive belt mechanisms; the two abrasive belt mechanisms are separately horizontally arranged at different heights; an upper end of each abrasive belt is fixedly connected with the corresponding guiding groove plate; an S-shaped material guiding groove is formed in a lower end surface of each guiding groove plate; an upper end of the reversing guide rail mechanism is connected with a material outlet end of the S-shaped material guiding groove in the upper end abrasive belt mechanism; a lower end of the reversing guide rail mechanism is connected with a material inlet end of the S-shaped material guiding groove in the lower end abrasive belt mechanism; each abrasive belt mechanism comprises an abrasive belt, a servo motor and two groups of belt wheels which are parallelly arranged; an output shaft of each servo motor is connected with one group of the corresponding belt wheels; and every two groups ofthe belt wheels are connected through the corresponding abrasive belt. The deburring device is used for deburring machining of small stamped parts.
