placing a steel pipe to be polished into a storage space 21 of the loading frame 20, leading the steel pipe to be polished into a blanking port 24 through a right guide plate 22 and a left guide plate 23 which are obliquely arranged in the storage space 21, and keeping the steel pipe to be polished after entering the bottom of the blanking port 24 still under the blocking of a movable baffle 26 and a limiting baffle 27;

then, the rotating disc 31 of the rotating and fixing mechanism 30 is controlled to rotate, so that the clamping head 34 on the rotating disc 31 and the steel pipe to be polished are positioned on the same axis, and at the moment, the clamping head 34 is controlled to extend into the hole of the steel pipe to be polished, so that the clamping head 34 clamps the steel pipe to be polished from the front side and the rear side to realize clamping;

then, the rotating disc 31 is controlled to rotate, so that the clamping head 34 and the steel pipe to be polished are driven to rotate, the movable baffle 26 is extruded to rotate when the steel pipe to be polished rotates, the gravity ball 273 in the limiting baffle 27 is not limited by the movable baffle 26, the pressing head 274 is pulled down to press the blocking plate 28 under the action of gravity, the blocking plate 28 is driven to extend rightwards into the blanking port 24, and the steel pipe to be polished above is prevented from falling into the bottom of the blanking port 24;

after the steel pipe to be polished on the clamping head 34 rotates out of the blanking port 24, the movable baffle 26 is not extruded and resets under the action of the biasing spring, so that the movable baffle 26 pushes the gravity ball 273 to reset upwards, the blocking plate 28 resets under the action of the resetting spring, and the blocked steel pipe to be polished enters the bottom of the blanking port 24 so as to be clamped by the clamping head 34 next time;

and finally, after the clamping head 34 drives the steel pipe to be polished on the clamping head to the polishing seat 40, controlling the clamping head 34 to drive the steel pipe to rotate, and further polishing the steel pipe by the polishing seat 40.

In the above steps, the concrete steps of clamping the steel pipe to be polished by the clamping head 34 are as follows: electrifying the electromagnet 331 of the thrust head 33, and enabling the electromagnet 331 to push the clamping head 34 to clamp the steel pipe to be polished by the principle that like poles of the electromagnet 331 and the magnet 341 on the clamping head 34 repel each other, then under the pressure of the electromagnet 331, the pressure block 344 under the magnet 341 presses the side abutting block 345, so that the side abutting block 345 extends out of the clamping head 34 to abut against the inner pipe wall of the steel pipe to be polished, and clamping and fixing the steel pipe to be polished;

the concrete steps of driving the steel tube to rotate through the clamping head 34 are as follows: after the clamping head 34 is pushed by the electromagnet 331, the shroud plate 342 is driven to slide along the thrust block 33, so that the driven gear 343 on the shroud plate 342 is engaged with the driving gear 321, at this time, after the power motor 32 is started to drive the driving gear 321 to rotate, the driven gear 343 drives the clamping head 34 and the steel pipe on the clamping head 34 to rotate under the driving of the driving gear 321, and then the polishing seat 40 is enabled to polish the steel pipe conveniently.
