[0033] The working principle of the present invention is as follows: pipes are stacked at the feed port above two guide plates. When the sensor on the self-locking device detects that the feed port is full of pipes, the self-locking device is unlocked, and the pipes naturally fall to the grinding station due to gravity. The motor drives the rotating wire wheel to rotate, and the four grinding devices correspond to each other in pairs to jointly deburr the end faces of both ends of the pipes. After the processing is completed, the pipes enter the discharge port, and the processed pipes are pushed to the collection device in an orderly manner by the pushing rod device; the distance adjuster can adjust the width of the pipe slot, so that the device can be suitable for processing pipes of different widths; the position of the internal thread connection block on the screw can be adjusted by rotating the rocker, so that the distance between the mobile bin combination and the fixed bin group can be adjusted, thereby achieving deburring of both ends of pipes of different lengths.
