[0045] A fluid grinding process of the present invention, grinding the product 1 by the above-mentioned rough grinding device 2 and the fluid grinding device 3, comprises the following steps:

[0046] S100: placing the product 1 to be polished on the fixture 21, and using the manipulator 22 to polish the surface of the product 1; wherein the product 1 has an upper end surface, a side surface and a lower end surface, and the manipulator 22 polishes the upper end surface, the side surface and the lower end surface of the product 1 respectively, and when polishing each surface, the manipulator 22 is in a clockwise or counterclockwise direction;

[0047] S200: removing the product 1 from the fixture 21 and placing it into the fluid grinding device 3, fixing the product 1 on the grinding mechanism 32 and moving the grinding mechanism 32 and the abrasive barrel 34 toward each other, so that the product 1 extends into the abrasive barrel 34, the second driving mechanism drives the product 1 to rotate to generate friction with the abrasive, and the first driving mechanism 33 drives the product 1 to move up and down continuously, so as to polish the product 1 in the vertical direction;

[0048] S300 : the grinding mechanism 32 and the abrasive barrel 34 move in opposite directions to take out the product 1 . During the movement, the blowing component 35 sprays air to the product 1 to clean the surface of the product 1 .

[0049] The working method of one embodiment of a fluid grinding process of the present invention is as follows: In step S100, the product 1 to be ground (hereinafter referred to as product 1) is first placed on the fixture 21, specifically, on the support portion, so that the lateral sides and the upper end of the second sub-portion 213 provide support for the lateral side edges of the product 1, and the first sub-portion 212 is supported inside the product 1, please refer to Figure 2 . Drive the manipulator 22 to move to drive the grinding block 221 to grind the product 1. When grinding, the upper end face, the side face, and the lower end face are grinded in sequence. When grinding each face, the manipulator 22 drives the grinding block 221 to grind around the outline of the product 1 in a clockwise direction or a counterclockwise direction. The three grindings of upper, middle, and lower are intended to remove the knife marks on the surface of the product 1 (the knife marks are left by the previous processing step). During the grinding process, water from an external water source flows to the manipulator 22 through the water pipe 231 and the hose 232, cools down the grinding block 221 and the product 1, and can also wash away the debris ground off the product 1. The water then falls into the receiving groove 233, and then flows into the water bucket 234 through the short pipe.

[0050] In step S200, the product 1 is fixed on the rotating shaft 323 through the protrusion, the first motor 332 is driven to rotate forward, and the screw rod 331 is driven to rotate forward. Under the limit cooperation of the support rod 312 on the flat plate 321, the flat plate 321 moves downward with the rotation of the screw rod 331 until the rotating shaft 323 extends into the abrasive barrel 34, so that the product 1 is buried in the abrasive of the abrasive barrel 34. The second motor 326 is started, and the second motor 326 drives the rotating disk 322 to rotate, and the rotating disk 322 drives the plurality of rotating shafts 323 to perform orbital motion around the axis of the rotating disk 322. At the same time, under the meshing matching of the first gear 324 and the second gear 325, the plurality of rotating shafts 323 simultaneously rotate, so that the product 1 can be more fully in contact with the abrasive. During polishing, the first driving mechanism 33 drives the product 1 to move back and forth up and down to polish the dead angle of the product 1 and the upper and lower surfaces of the workpiece, thereby achieving a 1360-degree polishing function without dead angles for the product.

[0051] In step S300, the product 1 is in full contact and friction with the abrasive, and the knife marks on the surface of the product 1 are removed. At this time, the first motor 332 is driven to reverse, driving the screw 331 to reverse, so that the plate 321 moves up until the product 1 leaves the abrasive barrel 34. In the initial state, the fan 351 is tilted downward, that is, the fan 351 blows air diagonally downward. In the process of the plate 321 driving the product 1 to move up, it drives the slider 356 made of metal material to move up in the support rod 312 through the magnet 359. When the slider 356 moves up, the gas inside the support rod 312 located on the upper part of the slider 356 is squeezed, so that part of the gas passes through the air pipe 357 and enters the annular airbag 358. The annular airbag 358 expands and protrudes downward from the third cavity and enters the annular groove 3521, pressing down the rear end of the fan 351, so that the fan 351 gradually rotates from the opening obliquely downward to the horizontal and then to the opening obliquely upward, that is, the air outlet direction of the fan 351 rises as the product 1 rises, ensuring that the wind can always blow on the product 1 and blow at different positions of the product 1 to achieve a better cleaning effect. At the same time, when the first motor 332 rotates, its power is transmitted to the rotating ring 352 through the third gear 353 and the fourth gear 354 to rotate it, and the rotating ring 352 drives a plurality of the fans 351 to rotate, blowing on different directions of the product 1, and achieving a better cleaning effect.
