at the moment, the driving assemblies in the movable seat 103 and the rotating seat 104 are started, so that the rotating block 3 is driven to rotate, the three rotating columns 305 are enabled to rotate along with the rotation, the three rotating rods 303 are enabled to rotate at the moment, the three limiting blocks 302 are driven to respectively slide on the inner walls of the three limiting frames 301, at the moment, the three extrusion blocks 304 are enabled to move outwards along with the movement of the three limiting blocks 302, and are enabled to be extruded with the inner walls of the pressure container along with the movement, and the pressure container is enabled to be in a central position when being fixed and convenient to polish;

at the moment, the pushing motor 409 is started, the pushing motor 409 is of the existing mature structure, and is of a model number YE2-112M-4, the invention is not explained here, the screw rod 401 is driven to rotate, so that the sliding seat 402 slides along the screw rod 401, the limiting column 404 is driven to move, the two pushing rods 405 are driven to rotate along the limiting column 404 along with the movement of the limiting column 404, and the two pushing plates 406 move oppositely along with the rotation of the two pushing rods 405, so that the two connecting plates 407 and the moving plate 408 are driven to move oppositely;

when the two moving plates 408 move toward each other, the two driving rods 502 on the opposite sides of the two arc-shaped sanding blocks 102 are driven to move, and along with the movement of the two driving rods 502, so that the two second driven links 503 and the two first driven links 501 are rotated along both ends of the driving link 502, since the two first driven rods 501 are rotatably connected to the outer surface of the connecting column 505, the two pushing seats 504 are pushed to move, at this time, the two arc-shaped sanding blocks 102 can move towards each other, therefore, the two arc-shaped polishing blocks 102 are attached to the pressure container, the moving seat 103 and the rotating seat 104 are driven to rotate by the rotating motor 105, the rotating motor 105 is of the existing mature structure, and the model is YE2-112M-4, the invention is not explained here, so that the pressure container is driven to rotate, and the polishing effect of the pressure container is better;

after polishing, carry out above-mentioned opposite movement for two arc sanding blocks 102 and pressure vessel phase separation, remove seat 103 and the inside drive assembly of seat 104 through the start this moment, make two turning blocks 3 carry out reverse rotation, make three extrusion piece 304 all with the pressure vessel phase separation can, make this moment remove seat 103 and carry out reverse removal, thereby make to remove seat 103 and pressure vessel phase separation, can be convenient for take out the pressure vessel who polishes the completion this moment.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
