The working steps of the stainless steel valve rod polishing machine in the embodiment are as follows: the valve rod penetrates through the mounting cylinder 601, the side wall of the valve rod pushes the limiting ball 604, the ball supporting plate 603 and the adjusting rod 607 to move, the limiting spring 605 is compressed, meanwhile, the elastic force of the limiting spring 605 enables the limiting ball 604 to be abutted against the side wall of the valve rod, so that the position of the valve rod is limited, the limiting screw 610 is rotated to drive the limiting block 611 to push the adjusting ring 608 to axially move along the mounting cylinder 601 until the adjusting ring 608 is attached to the end face of the adjusting rod 607, and therefore the adjusting rod 607 and the ball supporting plate 603 are limited.
After the end part of the valve rod extends into the space between the two clamping blocks 404, the two-way screw 406 is rotated to drive the two adjusting plates 405 to move in opposite directions, the adjusting plates 405 drive the clamping rods 403 and the clamping blocks 404 to move in opposite directions until the clamping blocks 404 are abutted against and pressed on two sides of the end part of the valve rod, so that the valve rod is clamped, the wedge blocks 10 are pushed to horizontally move by rotating the lifting screw 11, so that the lifting table 8 and the polishing mechanism 9 are pushed to ascend through the wedge blocks 10 until abrasive cloth on the circumferential surface of the polishing disc 903 is attached to the surface to be polished of the valve rod, the sliding seat 12 is pushed to slide in the third sliding groove 103, the sliding seat 12 drives the positioning block 13 and the positioning ball 14 to horizontally move until the positioning ball 14 is attached to the end surface of the valve rod, and the end part of the positioning rod 16 extends into the positioning hole 121 to position the sliding seat 12, the positioning block 13 and the positioning ball 14 through the elastic action of the positioning spring 17.
The clamping mechanism 4 and the valve rod are driven to synchronously rotate by the driving motor 3, the sliding plate 5 is driven to slide along the first sliding chute 101 by external force, the polishing block 606 is driven to polish the position to be polished on the surface of the valve rod, the sliding sleeve 7 is driven to slide along the second sliding chute 102 by external force, the lifting table 8 and the polishing mechanism 9 are driven to axially move along the valve rod, meanwhile, the polishing disc 903 and the driving gear 907 are driven to rotate by the polishing motor 902, the abrasive cloth on the circumferential surface of the valve rod is polished and deburred by the abrasive cloth on the circumferential surface of the polishing disc 903, abrasive dust generated in the polishing process is attached to the surface of the abrasive cloth, the driving gear 907 drives the driven gear 908, the horizontal shaft 905 and the brush roller 906 to rotate, the abrasive cloth on the circumferential surface of the polishing disc 903 is cleaned by the brush roller 906, the abrasive dust attached to the abrasive cloth is removed, the first magnet block 911, the return spring 910 and the mounting ring 909 are driven to synchronously rotate in the rotating process of the brush roller 906, a repulsive force is periodically generated between the first magnet piece 911 and the second magnet piece 912, and the return spring 910 is periodically extended; under the combined action of the repulsive force and the repulsive force of the return spring 910, the brush roller 906 generates reciprocating movement along the axial direction of the horizontal shaft 905, so that the abrasive cloth on the circumferential surface of the polishing disc 903 can be cleaned from different directions, the brush roller 906 periodically impacts the ball 914 and generates vibration in the reciprocating movement process on the horizontal shaft 905, and abrasive dust attached to the brush roller 906 is vibrated down through the vibration, so that the abrasive dust is prevented from being adhered to the surface of the abrasive cloth on the circumferential surface of the polishing disc 903 again.
After the valve rod is ground and polished, the clamping effect of the clamping mechanism 4 on the valve rod is removed, the sliding seat 12, the positioning block 13 and the positioning ball 14 are pushed to move until the positioning ball 14 is separated from the end face of the valve rod, and then the valve rod is pulled out.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention.
