[0046] Working principle:

[0047] First, when the first grinding end 7 and the second grinding end 8 grind the two wheel hubs on the conveyor frame group 4, it is necessary to raise the first telescopic device 92 on the dust suction and polishing device 9, so that the lifting frame 93 drives the first dust suction head group 952 and the second dust suction head group 953 to pass through the middle of the first roller conveyor frame and the second roller conveyor frame respectively, so that the first L-shaped suction nozzle 9521 rises and is located on the left side of the left wheel hub. The first L-shaped suction nozzle 9521 is used for negative pressure suction and collection of iron slag generated when the first grinding end 7 grinds the weld seam of the outer ring of the left wheel hub. At the same time, the second L-shaped suction nozzle 9531 is raised to pass through the middle cavity of the right wheel hub. The second L-shaped suction nozzle 9531 is used to The second grinding end 8 collects the iron slag generated when the inner ring weld of the right wheel hub is ground by negative pressure suction, and the vacuum cleaner 951 provides negative pressure suction to the first vacuum head group 952 and the second vacuum head group 953 to absorb the iron slag. The above is the auxiliary iron slag absorption operation of the vacuum polishing device 9 when the first grinding end 7 and the second grinding end 8 are grinding the weld. It should be noted that the coordinated operation method of conveying, flipping and transferring, pressing and clamping, and grinding among the conveying frame group 4, the clamping flipping mechanism 5, the pressing mechanism 6, the first grinding end 7, and the second grinding end 8 has been disclosed in our company's patented wheel hub weld grinding device, and will not be described in detail here.

[0048] In addition, when the second grinding end 8 completes the grinding of the weld seam of the inner ring of the right wheel hub of the conveyor frame group 4, the second grinding end 8 is initially reset, and then the inner sleeve seat 9532 is pushed to the left by the fifth telescopic device 9533, so that the first through-hole 932 and the second through-hole 9534 are opened, and then the second telescopic device 942 rises, so that the first roller head 9462 and the second roller head 9463 pass through the first through-hole 932 and the second through-hole 9534. When the polishing floppy disk 94524 rises to the a1 horizontal position of the right wheel hub, the second telescopic device 942 is first servo-paused, and then the two-way telescopic device 9454 retracts to make the first polishing head 9452 and the second polishing head 9453 slide in the expansion and contraction position. The rail 9451 is closed, and at this time, the two polishing soft disks 94524 will softly press against the inside and outside of the lower end of the weld after grinding on the right wheel hub, and the synchronous first roller head 9462 and the second roller head 9463 will softly press against the right outer wall of the right wheel hub, and the synchronous electromagnetic suction cup 9435 cancels the electromagnetic adsorption connection on the right side of the displacement slide 9433, so that the spring 9437 provides a left pulling force to the displacement slide 9433, so that the wheel 94622 can be close to the right outer wall of the right wheel hub, and then the second telescopic device 942 servo drives the two polishers 94523 to rise and then fall for travel. The spacing of each travel of the second telescopic device 942 is the polishing soft disk. The thickness of the disk 94524 is 1s, and the interval time is 1s. During the movement, due to the coordinated assistance of the wheel 94622 and the spring 9437, the displacement slide 9433 automatically slides left and right in the displacement slide groove 9432, so that the two polishers 94523 can adapt to the right outer wall curved surface of the right wheel hub for automatic left and right displacement adjustment. After the two polishing disks 94524 rotate and polish, they first rise and then fall to a1, and the two-way retractor 9454 extends to widen the distance between the two polishing disks 94524, and the wheel 94622 cancels the pressure on the right outer wall, and the synchronous third retractor 9434 drives the electromagnetic suction cup 9435 to move the electromagnetic adsorption displacement slide 94524 to the left. On the right side of 433, the displacement seat group 943 is initially reset, and then the second telescopic device 942 drives the first roller head 9462 and the second roller head 9463 to descend through the first through-hole 932 and the second through-hole 9534 to perform the descending reset of the polishing mechanism 94, and then the first telescopic device 92 descends, causing the first dust collection head group 952 and the second dust collection head group 953 to descend briefly, so that the second roller conveyor frame can convey the hub to the right to discharge the material, and the clamping claw flipping mechanism 5 can be used to clamp the hub on the first roller conveyor frame and flip it to the second roller conveyor frame, and facilitate the rising of the first roller conveyor frame to re-feed, thereby completing the automated processing of grinding, polishing and dust collection of the inner and outer rings of the hub.

[0049] It should also be noted that after the first vacuum head group 952 and the second vacuum head group 953 are briefly lowered, the fourth telescopic device 9523 extends to the left to push the first L-shaped suction nozzle 9521 to tilt 65° to the left on the swing seat 9524. After the first L-shaped suction nozzle 9521 tilts and swings at an angle, the iron slag remaining at the bottom of the cavity of the first L-shaped suction nozzle 9521 will flow to the first discharge port 9522 and be more easily sucked away by negative pressure.

[0050] In addition, when the fifth telescopic device 9533 pushes and pulls the inner sleeve seat 9532 left and right, the inertia generated in this process will make it easier for the iron slag remaining on the slope surface 9535 to flow to the second discharge port 9536 and be sucked away by the negative pressure.

[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
