Description

Technical Field

[0002] A hub is a cylindrical metal component that supports the tire inside the tire profile and is centered on the axle. It is also called a wheel rim, steel rim, wheel, or tire bell.

[0003] During the processing of the outer ring of the hub, an iron sheet needs to be first rolled and pressed into a circular outer ring, and then the interface of the circular outer ring is welded. The welded weld needs to be processed through procedures such as grinding and polishing. The existing grinding method uses traditional manual grinding. When manually grinding, the iron slag generated will fly everywhere, polluting the working environment. Moreover, after grinding, manual polishing of the weld is also required. The above processing of the weld is very troublesome and the processing efficiency is low. In response to the above needs, the present invention proposes a multi-functional processing device for hub welds. Summary of the Invention

The first dust suction head group also has the function of automatically swinging to the left by an angle to clean the residual iron slag at the bottom of the first L-shaped suction nozzle cavity. The left and right sliding function of the inner sleeve seat can, while opening the rising channel for the polishing mechanism, also strengthen the function of automatically cleaning the residual iron slag by the inertial movement of the residual iron slag on the inclined plane at the bottom of the inner sleeve seat cavity, without the need for workers to regularly clean the residual iron slag.

[0019] Among them, the combined design of an L-shaped frame, a second telescopic device, a displacement seat group, a second stable sliding rod, a polishing head group and a positioning component constitutes a polishing mechanism. This mechanism is lifted by the servo stroke of the second telescopic device, and under the coordinated cooperation of the leftward pulling force provided by the displacement seat group and the soft rolling of the positioning component against the right side of the hub, when the polishing head group rotates and polishes and positions, it can automatically adapt to the curved surface of the hub for automatic left and right displacement, so that both polishing floppy disks can always softly abut against the inner and outer welds of the hub for polishing, without the problem of incomplete polishing.

[0020] Through the above, the device of the present invention has functions such as assisting in sucking iron slag and automatically cleaning residual iron slag while having an automatic grinding function, and also has an automatic synchronous polishing function along the inner and outer welds of the hub curved surface. After the hub welds are ground, there is no need to transfer it to another device for weld polishing, effectively shortening the process and improving the processing efficiency.

[0028] The positioning component 946 includes a vertical frame 9461. On the front and rear ends of the left side surface of the vertical frame 9461, a first abutting roller 9462 and a second abutting roller 9463 are inclinedly arranged.

[0029] The first abutting roller head 9462 includes a pushing arm 94621, and a abutting wheel 94622 is movably connected to the upper end of the pushing arm 94621. A plurality of anti-jamming convex grains 94623 are arranged in an annular array on the inner side of the wheel rim of the abutting wheel 94622. The abutting wheel 94622 is made of rubber material.

[0030] The first dust suction head group 952 includes a first L-shaped suction nozzle 9521.

When the fourth telescopic device 9523 extends leftward, it pushes the first L-shaped suction nozzle 9521 to swing leftward by 65-75° on the swing seat 9524.

[0031] The second dust suction head group 953 includes a second L-shaped suction nozzle 9531. An inner sleeve seat 9532 is horizontally movably sleeved on the lower end of the second L-shaped suction nozzle 9531. A fifth telescopic device 9533 is horizontally arranged between the second L-shaped suction nozzle 9531 and the inner sleeve seat 9532.

A second discharge port 9536 is opened on the left side surface of the inner sleeve seat 9532. A second suction hose 9537 for communicating with the vacuum cleaner 951 is connected to the second discharge port 9536.

[0032] Working principle: First, when grinding the two hubs on the conveying rack group 4 at the first grinding end 7 and the second grinding end 8, 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 parts of the first roller conveying rack and the second roller conveying rack respectively, making the first L-shaped suction nozzle 9521 rise to the left side of the left hub. The first L-shaped suction nozzle 9521 is used to collect the iron slag generated during the grinding of the outer ring weld of the left hub by the first grinding end 7 through negative pressure suction. Synchronously, the second L-shaped suction nozzle 9531 rises through the middle cavity of the right hub. The second L-shaped suction nozzle 9531 is used to collect the iron slag generated during the grinding of the inner ring weld of the right hub by the second grinding end 8 through negative pressure suction. The vacuum cleaner 951 provides negative pressure suction for the first dust suction head group 952 and the second dust suction head group 953 to suck the iron slag. The above is the auxiliary iron slag suction operation of the dust suction and polishing device 9 during the grinding of the welds at the first grinding end 7 and the second grinding end 8. It should be noted that the cooperative operation methods among the conveying, turning and transferring materials, pressing and clamping materials, and grinding between the conveying rack group 4, the jaw turning mechanism 5, the pressing mechanism 6, the first grinding end 7, and the second grinding end 8 have been disclosed in the company's patent for a hub weld grinding device, and will not be elaborated in detail here.

[0033] In addition, when the second grinding end 8 finishes grinding the weld seam inside the inner ring of the right hub of the conveying rack group 4, the second grinding end 8 is initially reset. Then, the fifth telescopic device 9533 pushes the inner sleeve seat 9532 to move leftward, opening the channels of the first through-hole 932 and the second through-hole 9534. Then, the second telescopic device 942 rises, enabling the first pressing roller head 9462 and the second pressing roller head 9463 to pass through the first through-hole 932 and the second through-hole 9534. When the polishing flexible disk 94524 rises to the a1 level position of the right hub, the second telescopic device 942 first servo-pauses, and then the bidirectional telescopic device 9454 retracts, causing the first polishing head 9452 and the second polishing head 9453 to close on the expansion and contraction slide rail 9451. At this time, the two polishing flexible disks 94524 will softly abut against the inner and outer sides of the lower end of the weld seam after grinding of the right hub. Synchronously, the pressing wheels 94622 on the first pressing roller head 9462 and the second pressing roller head 9463 will softly press against the outer wall on the right side of the right hub. Synchronously, the electromagnetic chuck 9435 cancels the electromagnetic adsorption connection with the right side surface of the displacement slide seat 9433, enabling the spring 9437 to provide a leftward pulling force to the displacement slide seat 9433, allowing the pressing wheel 94622 to closely adhere to the outer wall on the right side of the right hub. Then, the second telescopic device 942 servo-drives the two polishers 94523 to first rise and then descend for a stroke movement. The stroke movement spacing of the second telescopic device 942 each time is the thickness of the polishing flexible disk 94524, and the interval time is 1 s. During the movement, due to the coordinated auxiliary cooperation of the pressing wheel 94622 and the spring 9437, the displacement slide seat 9433 automatically slides left and right within the displacement chute 9432, enabling the two polishers 94523 to automatically adjust their left and right displacement movements to adapt to the curved surface of the outer wall on the right side of the right hub. After the two polishing flexible disks 94524 rotate and polish, first rise and then descend to the a1 position, the bidirectional telescopic device 9454 extends to separate the two polishing flexible disks 94524, and the pressing wheel 94622 cancels the pressing on the outer wall on the right side. Synchronously, the third telescopic device 9434 drives the electromagnetic chuck 9435 to move leftward to electromagnetically adsorb the right side surface of the displacement slide seat 9433, performing the initial reset of the displacement seat group 943. Then, the second telescopic device 942 drives the first pressing roller head 9462 and the second pressing roller head 9463 to descend through the first through-hole 932 and the second through-hole 9534 for the downward reset of the polishing mechanism 94. Then, the first telescopic device 92 descends, causing the first dust suction head group 952 and the second dust suction head group 953 to briefly descend, facilitating the rightward conveying of the hub by the second roller conveying rack and the clamping and flipping of the hub on the first roller conveying rack to the second roller conveying rack by the clamping jaw flipping mechanism 5, and facilitating the upward re-feeding of the first roller conveying rack, completing the automated processing of grinding, polishing, and dust suction of the inner and outer rings of the hub.

[0034] It should be further noted that after the first dust suction head group 952 and the second dust suction head group 953 briefly descend, the fourth telescopic device 9523 extends leftward to push the first L-shaped suction nozzle 9521 to swing leftward at an angle of 65° on the swing seat 9524. After the first L-shaped suction nozzle 9521 swings at an inclined 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 is more easily sucked away by negative pressure.

[0035] In addition, when the fifth telescopic device 9533 pushes and pulls the inner sleeve seat 9532 left and right, the inertia generated during this process will make the iron slag remaining on the inclined plane 9535 move more easily and flow to the second discharge port 9536 to be sucked away by negative pressure.
