[0002] After a series of processing such as cutting and drilling, burrs are usually generated in the holes of the workpiece. In order to ensure the accuracy and quality of the workpiece, the workpiece needs to be deburred after it is produced. The current deburring method usually adopts manual deburring, that is, the operator holds the workpiece in one hand and the electric drill in the other hand, and extends the rotating rod set on the electric drill chuck of the electric drill into and out of the holes of the workpiece. At this time, the twisted wire brush wrapped on the rotating rod can remove the burrs in the hole. There are multiple holes at different positions and depths on each workpiece, so the operator needs to constantly adjust the position of taking the workpiece and the insertion position of the rotating rod, which requires the operator to maintain a high degree of concentration, thus consuming a lot of energy of the operator, but the operator's energy is limited. On the one hand, it is difficult to ensure the accuracy and precision of deburring for a long time, and on the other hand, the operation speed gradually slows down, thereby affecting the quality and processing efficiency of the workpiece.
