As the number of the fan blades 600 is increased along with the increase of the polishing head 320, the area of the fan blades 600 is also increased, so that a larger blowing amount can be provided when facing the valve pipe member 100 with a larger diameter, and the impurities falling during polishing can be removed in an auxiliary manner while polishing.
With the above embodiments, the usage principle and the working process of the present invention are as follows:
before grinding, the valve pipe fitting 100 to be ground is fixed through a clamping device, the sliding seat 410 is driven to move towards the motor 500, the traveling wheel 210 of the feeding device 200 is positioned on the inner wall of the valve pipe fitting 100, and then the sliding seat 410 is locked and does not slide any more.
In use, an operator rotates the first gear ring 270, the first gear ring 270 rotates to drive the stop collar 290 to rotate, the stop collar 290 rotates to enable the first inclined surface 291 on the stop collar 290 to be matched with the outer wall of the cylinder 310, the ball rod 370 of the polishing mechanism rotates in the rotating groove 515, when the ball rod 370 of the polishing mechanism rotates in the rotating groove 515 to a position perpendicular to the rotating shaft 510, the stop collar 290 rotates to enable the second inclined surface 292 of the stop collar to be in contact with the polishing mechanism, the polishing mechanism is further pushed to enable the polishing mechanism to enter the annular groove 516, and then the stop collar 290 rotates to push the next polishing mechanism, and at least one polishing mechanism is pushed out.
And the second gear 2100 is engaged with the right end of the first gear ring 270, so when the operator rotates the first gear ring 270 in use, the first gear ring 270 rotates to drive the second gear 2100 to rotate at the same time, and the first screw 250 and the inner end surface of the second gear 2100 are in spiral transmission, so that the second gear 2100 rotates to move the first screw 250 upwards. The mounting rack 220 moves upwards synchronously with the first screw 250, the traveling wheel 210 is installed on the mounting rack 220 in a rolling manner, and moves upwards synchronously with the mounting rack 220, when the mounting rack 220 moves upwards to contact with the inner wall of the valve pipe fitting 100, the first gear ring 270 continues to rotate to drive the second gear 2100 to rotate, so that the first screw 250 continues to extend, and the mounting rack 220 cannot continue to move to extrude the first spring.
Therefore, when the first screw 250 continues to extend to press the first spring, the first gear 260 will be rotated, the first gear 260 is a duplicate gear, and the second rack 240 is engaged with the other gear of the first gear 260, so that the second rack 240 will be driven to move toward the motor. The second rack 240 moves to push the second gear 280 to move, so that the second gear 280 is close to the locking rod 360 and is in contact with the upper end of the locking rod 360, the upper end of the locking rod 360 is arranged to be an inclined plane, the locking rod 360 is enabled to move towards the direction of the ball rod 370 along with the movement of the second gear 280, the locking ring 380 is enabled to move to be separated from the spring expansion plate 350, the spring expansion plate 350 is unlocked and extends out along the circumferential direction, the grinding mechanisms move in the ring groove 516, the position of each grinding mechanism in the ring groove 516 is adjusted through the spring expansion plate 350, and the plurality of grinding mechanisms are uniformly distributed in the ring groove 516.
When the second gear 280 moves, the limiting ring 290 is driven to move synchronously, so that the limiting ring 290 is disengaged from the first gear 270, the first gear 270 continues to rotate, the limiting ring 290 cannot continue to rotate to push out the polishing mechanism, that is, when the traveling wheel 210 contacts the valve pipe fitting 100, the limiting ring 290 finishes pushing out the polishing mechanism to be used before the first spring is compressed, and the polishing mechanism is not pushed out continuously after the first spring is compressed.
The first gear ring 270 continues to rotate, so that the second gear ring 280 continues to move, the second gear ring 280 is meshed with the fourth gear 345, the rotation stop rod 512 at the lower end of the second gear ring 280 is positioned at the right end of the stepped groove, the locking of the second gear ring 280 is released, the second gear ring 280 can rotate, the torsion spring 275 is released, the fourth gear 345 is driven to rotate rapidly by the rotation of the second gear ring 280, the fourth gear 345 and the second screw 330 are coaxially arranged, and the second screw 330 and the sanding head 320 are in spiral transmission, so that the sanding head 320 extends out.
