[0022] First, the steel pipe body 2 is placed on one side of one of the turntables 18. At this time, according to the diameter of the pipe mouth of the steel pipe body 2, the grinding mechanism is rotated to adjust the spacing between the grinding brushes 19 to a suitable distance.

Then, the clamping mechanism is started to drive the two clamping blocks 3 to approach the outside of the steel pipe body 2. Through the grooves opened inside the clamping blocks 3, it is suitable for fixing steel pipe bodies 2 of different diameters. The position of the steel pipe body 2 can be fixed by the clamping mechanism, avoiding the phenomenon of rotation of the steel pipe body 2 during grinding, thereby increasing the stability of the device. Finally, the output shaft of the first motor 5 is started to rotate to drive the turntable 18 to rotate and at the same time drive the two grinding brushes 19 to grind the inner and outer walls of the steel pipe body 2 to remove burrs.

[0023] like Figure 1-Figure 4 As shown, the clamping mechanism includes a first bidirectional screw rod 6, which is rotatably connected between two second vertical plates 12, wherein a second motor 7 is fixedly installed on one side of one of the second vertical plates 12, and one end of the output shaft of the second motor 7 is fixedly connected to one end of the first bidirectional screw rod 6, and the outer side of the first bidirectional screw rod 6 is connected to the internal thread of the clamping block 3.

[0024] When fixing the steel pipe body 2, first start the second motor 7 to rotate the output shaft to drive the first bidirectional screw 6 to rotate and drive the clamping block 3 to slide on the outside of the two slide bars 13. The sliding bar 13 can control the moving direction of the clamping block 3. Then, the clamping block 3 slides inside the displacement groove 8, thereby increasing the movement stability of the clamping block 3.

Then, the movement of the displacement block 21 drives the grinding brush 19 to move, thereby adjusting to be suitable for steel pipe bodies 2 of different diameters.

[0027] The utility model provides a deburring device for a short section of a steel pipe, and the specific working principle is as follows: first, the second bidirectional screw rod 16 is driven to rotate by rotating the turning handle 15, and at the same time, the displacement block 21 is driven to slide on the outside of the fixed rod 20, and then the outer side of the displacement block 21 slides with the inner wall of the limiting groove 22, so as to limit the movement of the displacement block 21 and avoid the displacement when it moves.
