[0039] Through the arrangement of the above structure, the driving motor 33 is turned on to drive the driving disk 32 to rotate. Under the cooperation of the push-pull rod 35 and the hinge seat 34, the piston plate 3 will be driven to slide upward first, thereby generating a suction effect at the lower part of the inner cavity of the grinding cylinder 2, and thereby opening the one-way valve in the fluid extraction pipe 372, so that the fluid material in the fluid bin 37 is sucked into the grinding cylinder 2 along the fluid extraction pipe 372, and then under the rotation of the driving disk 32, the piston plate 3 will slide downward, thereby squeezing the fluid material in the grinding cylinder 2, so that the fluid material passes through various automotive parts under pressure, thereby realizing the grinding of automotive parts, and under the above pressure, the one-way valve in the fluid discharge pipe 371 will also be opened, so that the fluid material passes through the filter screen 36 and then returns to the fluid bin 37, thereby realizing the cyclical use of the fluid material, saving material consumption, and improving energy-saving effects. At the same time, multiple cycles of pressurized grinding are used to effectively improve the grinding efficiency and ensure the quality of automotive parts.

[0040] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8A rotating groove 4 is provided in the middle of the inner cavity of the base 1, and a rotating shaft 41 is rotatably connected in the rotating groove 4. The top of the rotating shaft 41 penetrates into the grinding cylinder 2 and is fixedly connected to the bottom of the filter screen 36, and a pneumatic impeller 42 is fixedly connected to the outer wall of the rotating shaft 41 located in the rotating groove 4, and a double-headed air pipe 43 is slidably connected in the fluid bin 37.

[0041] It should be noted that the one-way valve in the air supply pipe 45 can only allow the external airflow to be sucked into the driving chamber 31 ; the one-way valve in the air guide pipe 44 can only allow the gas in the driving chamber 31 to enter the rotating tank 4 .

[0042] Through the arrangement of the above structure, when the piston plate 3 slides upward, the gas in the upper cavity of the grinding cylinder 2 will be squeezed, and the one-way valve of the air guide pipe 44 will be opened, so that the compressed gas will enter the driving chamber 31 along the air guide pipe 44 and the double-headed air pipe 43, thereby applying thrust to the pneumatic impeller 42 from both sides, so that the pneumatic impeller 42 drives the rotating shaft 41 and the filter screen 36 to rotate, so that the fluid material is evenly covered on various automotive parts to be polished, thereby effectively ensuring the polishing effect.

[0043] Reference Figure 1 , Figure 2 and Figure 8 Among them, piston cylinders 5 are fixedly connected to both sides of the grinding cylinder 2, and an impact rod 51 is slidably connected inside the piston cylinder 5. A return spring 52 is fixedly connected between the impact rod 51 and the inner wall of the piston cylinder 5. The side wall of the piston cylinder 5 is fixed and connected to an air inlet pipe 53. The other end of the air inlet pipe 53 is connected to the inner cavity of the rotating groove 4. The bottom of the side wall of the piston cylinder 5 is fixed and connected to an air outlet pipe 54.

[0044] Through the arrangement of the above-mentioned structure, the gas after driving the pneumatic impeller 42 to rotate will be pressed into the piston cylinder 5 along the air inlet pipe 53, thereby pushing the impact rod 51 to move quickly toward the side wall of the grinding cylinder 2, so that vibration is generated in the grinding cylinder 2, so that the fluid material and the automobile parts fit more closely, effectively ensuring the grinding effect, and when the impact rod 51 hits the side wall of the grinding cylinder 2, the cavity on one side of the piston cylinder 5 filled with gas will be connected to the air outlet pipe 54, and the excess gas will be released at this time to achieve balanced control of the air pressure, so that the impact rod 51 can be reset, ensuring the subsequent continuous vibration.

[0045] Reference Figure 1-Figure 6, wherein the material mixing assembly includes two groups of stirring tubes 6, the two groups of stirring tubes 6 are respectively fixed on the fluid extraction tubes 372 on both sides, and the stirring tubes 6 are connected with the fluid extraction tubes 372, a stirring shaft 61 is rotatably connected in the stirring tube 6, a stirring impeller 611 is rotatably connected on the stirring shaft 61, a linkage shaft 62 is rotatably connected in the driving bin 31, the linkage shaft 62 is connected to the rotating shaft of the driving disk 32 through a first belt pulley set 621, and the outer ends of the stirring shafts 61 and the linkage shaft 62 on both sides are connected through a second belt pulley set 622; both sides of the grinding cylinder 2 are fixedly connected with a dripping tank 63, the bottom of the dripping tank 63 is fixed and connected with a dripping tube 631, and the dripping The bottom end of the tube 631 is connected to the top of the inner cavity of the stirring tube 6, and a sealing ring 64 is rotatably connected to the dripping tube 631.

A transmission gear ring 644 is fixedly connected to the outer wall of the sealing ring 64, and the transmission gear ring 644 is meshingly connected with the transmission gear 651.

[0046] It should be noted that, in the first pulley group 621, the diameter of the pulley connected to the driving disk 32 is larger than the diameter of the pulley connected to the linkage shaft 62; in the second pulley group 622, the diameter of the pulley connected to the linkage shaft 62 is larger than the diameter of the pulley connected to the stirring shaft 61; and the outer diameter of the transmission gear 651 is larger than the outer diameter of the transmission gear ring 644; in this way, through the above three groups of transmission structures, not only multiple linkage effects are achieved, but also acceleration effect is achieved, so that the rotation speed of the stirring shaft 61 is much greater than the rotation speed of the driving disk 32, ensuring the mixing and stirring effect of the stirring impeller 611.

[0047] Through the arrangement of the above structure, during the rotation of the driving disk 32, the stirring shaft 61 will be driven to rotate through the transmission effect of the first pulley group 621 and the second pulley group 622, so that the stirring impeller 611 rotates in the stirring tube 6, which can firstly help the fluid material to be discharged from the fluid extraction tube 372 more quickly, and secondly can break up the fluid material that is about to be output from the stirring tube 6 to avoid the occurrence of agglomeration, thereby improving the use effect of the fluid material; and when the stirring shaft 61 rotates, the bevel gear group 652 and the transmission gear ring 644 will be used to The transmission gear 651 drives the sealing ring 64 to rotate. Under the action of centrifugal force, the sealing sliders 642 on both sides of the sealing groove 641 will slide toward one side of the compression sealing spring 643 at the same time, so that the sealing sliders 642 on both sides are out of the state of blocking the drip tube 631. At this time, the polishing agent in the drip tank 63 will enter the stirring tube 6 along the drip tube 631, so as to be fully mixed with the fluid material under the rotation of the stirring impeller 611, so as to continuously replenish the polishing components in the fluid material, effectively improving the polishing effect.
