First, according to the size of the inner hole of the cylindrical workpiece, the driving gear 116 is driven to rotate by driving the rotating rod 6. The driving gear 116 drives the orbital gear 1 to rotate. During the rotation of the orbital gear 1, the clamping block 111 is driven to move in the orbital groove 110. During the movement of the clamping block 111, the slide rod 112 is driven to move in the limiting frame 113. During the movement of the slide rod 112, the grinding plate 115 is driven to move outwards through the expansion plate 114, so that the grinding plate 115 is attached to the inner wall of the cylindrical workpiece. Subsequently, the expansion mechanism and the grinding plate 115 are driven to rotate to polish the burrs in the inner hole of the cylindrical workpiece. By providing the expansion mechanism and the grinding plate 115, the grinding plate 115 can be closely contacted with the inner wall of the cylindrical workpiece by controlling the expansion mechanism, and then the burrs in the inner hole of the cylindrical workpiece are polished by rotating the grinding plate 115. It is not only convenient to use, but also greatly improves the work efficiency, and the cleaning effect of the burrs in the inner hole of the cylindrical workpiece is better.

[0023] At the lower surface of the six limiting frames 113, a connecting rod 2 is commonly fixedly provided at one end away from the expansion plate 114. The center of the orbital gear 1 is rotatably arranged at the center of the top end of the connecting rod 2. One end of the connecting rod 2 away from the limiting frame 113 is fixedly provided with a motor 3. The driving end of the motor 3 is coaxially fixedly installed with the bottom end of the connecting rod 2. By starting the motor 3, the connecting rod 2 is driven to rotate.

[0029] Working principle: First, according to the length of the cylindrical workpiece, a suitable grip rod 5 is replaced;

[0030] Subsequently, according to the size of the inner hole of the cylindrical workpiece, the driving device 7 is started to drive the rotating rod 6 to rotate. The rotating rod 6 drives the driving gear 116 to rotate, and the driving gear 116 drives the track gear 1 to rotate. During the rotation of the track gear 1, the block 111 is driven to move in the track groove 110. During the movement of the block 111, the slide rod 112 is driven to move in the limiting frame 113. During the movement of the slide rod 112, the abrasive plate 115 is driven to move outwards through the expansion plate 114, so that the abrasive plate 115 is attached to the inner wall of the cylindrical workpiece. Subsequently, by starting the motor 3, the connecting rod 2 is driven to rotate, and the connecting rod 2 drives the abrasive plate 115 to rotate through the expansion mechanism. The operator holds the grip rod 5 and moves the deburring device for the inner hole of the hollow cylindrical part to polish the burrs on the inner hole of the cylindrical workpiece.
