The working principle of the embodiment is as follows:

Firstly, the sealing plate 10 is rotated, the sealing plate 10 is taken down from the fixed column 9, the pull rod is sleeved on the surface of the fixed column 9, the sealing plate 10 is rotated again, and after the sealing plate 10 is screwed into the fixed column 9, the pull rod is directly clamped and fixed. The first servo motor 5 is started, the threaded rod 6 fixedly connected to the output end of the first servo motor is driven to rotate, the connecting plate 7 is driven to rotate while the threaded rod 6 rotates, and accordingly the fixing column 9 and the pull rod sleeved on the surface of the fixing column 9 are driven to move. After the pull rod moves to the lower part of the turning and milling mechanism 2, the turning and milling cutter performs turning and milling on the surface of the pull rod; after turning and milling are completed, the pull rod continues to move to reach the polishing mechanism, the telescopic rods 302 on the two sides are synchronously started, the polishing plates 3011 on the two sides are driven to move towards each other until the polishing plates 3011 contact the surface of the pull rod, the second servo motor 8 is started, the fixing column 9 is driven to rotate, and accordingly the pull rod is driven to rotate and is polished through continuous rotation.

The movable plate 308 can drive the pipe column 306 to move synchronously, and the free end of the pipe column 306 can extend out of the limit hole 3043 or retract into the limit hole 3043. When the tubular string 306 extends out of the spacing hole 3043, the spacing post 3082 is positioned in the transverse slot well 3042 with the first and second fixed plates 309, 3010 cooperatively clamping the sanding plate 3011. When the polishing plate 3011 needs to be replaced, the movable plate 308 is pulled, the movable plate 308 drives the pipe column 306 to move towards the pipe sleeve 305, the pipe column 306 gives a pressure to the spring 307, the movable plate 308 continues to move until the front end of the pipe column 306 is separated from the limiting hole 3043, the movable plate 308 moves while driving the pipe sleeve 305 to move, and the pipe sleeve 305 moves while driving the first fixed plate 309 to move. When the limiting post 3082 slides to the vertical groove hole 3042, it can break away from the limit of the horizontal groove hole 30441, and pull the movable plate 308 upwards, i.e. pull the limiting post 3082 into the vertical groove hole 3042, so that the first fixing plate 309 can be lifted synchronously, and the polishing plate 3011 can be replaced. After the replacement is completed, the movable plate 308 is pushed and pulled reversely, and the spring 307 pushes the pipe column 306 out of the limiting hole 3043 again due to self resilience, so that the pipe column is limited and fixed.

When equipment is polished, the suction fan 402 is started, suction force is generated inside the outer frame 401 by the suction fan 402, so that scraps and dust generated by polishing are adsorbed, finally, the scraps and dust are input into the dust removal filter box 403 through the output end of the suction fan 402, and finally, the dust removal filter box is subjected to manual unified treatment, and meanwhile, polishing conditions can be observed through glass on the upper surface of the outer frame 401 in real time.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit thereof, the scope of which is defined in the appended claims and their equivalents.
