[0007] In the above technical solution, preferably, the rear group of the two groups of No. 1 polishing wheels is fixed to the rotating shaft of the driving motor, and the upper and lower sides of the two groups of No. 1 polishing wheels and the three groups of No. 2 polishing wheels and No. 3 polishing wheels present a trapezoidal concave-convex state.

[0008] In the above technical solution, preferably, a plurality of groups of the sliding blocks are respectively slidably arranged in corresponding sliding grooves, the arc-shaped push frame is attached to the upper side of the fixed block, and the double-hook spring is in a stretched state.

[0009] In the above technical solution, preferably, the positioning shaft is matched with a plurality of groups of circular grooves, and the dust suction pipe is fixedly arranged with the air suction end of the dust suction pump.

[0011] In the above technical solution, the piston ring is matched with the cylindrical groove, the sealing cover is covered on the lower end of the round tube, and the two sides of the torsion spring are respectively inserted into the interior of the shaft block and the sealing cover.

[0012] A metal plate polishing method is also provided, which is used to operate a dust-free metal thin plate polishing device, comprising the following steps:

[0013] S1: Place the metal corrugated plate in a plurality of groups of grooves, and the metal corrugated plate is fixed by the suction cups in the pressing, and the cavity of the metal corrugated plate is supported and filled in the processing table and the grooves, so that during polishing, the metal corrugated plate is prevented from elastically deforming when under pressure;

[0014] S2: Since the suction cup and the round tube under the metal corrugated plate are not in correspondence, they will remain motionless due to being not under pressure, so the sealing cover will always cover under the round tube, and the suction cup that is not in contact with the metal corrugated plate will be in an open state, so as to avoid weakening the adsorption work in other working round tubes during the vacuum work;

[0015] S3: By rotating the connecting shaft through the disc, the No. 3 polishing wheel pushes the three groups of No. 2 polishing wheels to pull each other downward to form a shape that fits the metal corrugated plate for polishing. At the same time, the dust suction pipe and dust suction box can further improve the dust removal effect.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the metal corrugated plate is used for polishing, the protruding positions of the metal corrugated plate are placed corresponding to several groups of concave grooves, and the suction cups arranged in the several groups of concave grooves are pushed downward by their own gravity, and the No. 2 spring is compressed by the circular tube and the piston ring downward, and the suction cups are recovered to the inner side of the concave grooves, and the protruding position of the lower side of the metal corrugated plate is automatically stuck in the concave grooves. At this time, the downward moving circular tube will push the sealing cover to open, and then the dust suction pump will be started to exhaust air in the exhaust pipe, the two groups of branch pipes, and the dust suction pipe, and the exhaust pipe and the two groups of branch pipes will exhaust air in the partition and the conical shell, and the gas of the partition will be extracted by the exhaust pipe. At the same time, the suction cups in the pressure hold will respectively adsorb and fix the metal corrugated plate, and the cavity position of the metal corrugated plate is supported and filled in the processing table and the concave grooves. Therefore, during polishing, it is avoided that the metal corrugated plate is easily elastically deformed when under pressure, which affects the polishing of the metal corrugated plate.

[0018] Two groups of branch pipes respectively exhaust air in the conical shell, and several groups of dust suction ports are opened to vacuum the surroundings of the processing table. A dust extraction air wall is formed around it to absorb the dust generated by polishing to achieve dust-free work. When several groups of suction cups are in the initial state, they can also be adsorbed and fixed when facing flat metal sheets.

[0019] Several groups of sealing covers are respectively covered on the lower ends of the round tubes, so when the metal corrugated plate enters the concave groove, the suction cups and round tubes corresponding to the bottom of the metal corrugated plate will completely push open the sealing covers, and the suction cups and round tubes that do not correspond to the bottom of the metal corrugated plate will remain motionless because they are not under pressure, so the sealing covers will always cover the bottom of the round tubes, so that the suction cups that do not need to work will be in a closed state. When facing metal corrugated plates of different sizes, some suction cups that are not in contact with them are in an open state, and when the air is being pumped out, the adsorption work in other working round tubes is weakened.

[0020] Before polishing, the first spring is compressed by moving toward the front of the disc, and the positioning shaft leaves the corresponding circular groove. Then, the disc rotates the connecting shaft and the arc-shaped push frame, and the arc surface of the arc-shaped push frame pushes the fixed block and the third polishing wheel downward, while the sliders at both ends of the third polishing wheel slide in the second polishing wheels on both sides. Under the continuous rotation of the arc-shaped push frame, the third polishing wheel pushes the three groups of second polishing wheels set on both sides to pull each other downward, forming a shape that fits the metal corrugated plate (such as Figure 4 ), the positioning shaft is inserted into a corresponding set of circular grooves, and then cooperates with the three-axis electric slide and the drive motor to drive the No. 1 polishing wheel, the No. 2 polishing wheel, and the No. 3 polishing wheel to rotate, respectively polishing the surface of the metal corrugated plate.

[0021] By rotating the disc in the opposite direction to position it, the double-hook spring pulls up the No. 3 polishing wheel and the No. 2 polishing wheels on both sides, so that the No. 1 polishing wheel, the No. 2 polishing wheel and the No. 3 polishing wheel become coaxial, and can polish common flat metal sheets, suitable for processing two different plates. The dust is suctioned through the dust suction pipe and the dust suction box during the polishing work of the No. 1 polishing wheel, the No. 2 polishing wheel and the No. 3 polishing wheel, to further improve the dust removal effect.
