[0042] The shifting assembly includes a protrusion 61 annularly fixed to the chassis frame 1 near the material loading platform 3, and a toothed disc 62 is fixedly connected to the other output shaft of the double-headed motor 41. A planetary gear 63 is provided on the outer side of the toothed disc 62, and an electric telescopic rod 64 is fixedly connected to the planetary gear 63. First, the four electric telescopic rods 64 are controlled to adjust the meshing stroke between the toothed disc 62 and the four sets of planetary gears 63 to the right position, and then the double-headed motor 41 drives the four sets of planetary gears 63 to rotate synchronously through the toothed disc 62 engaged in place, and the electric telescopic rod 64 is fixedly connected to the planetary gear 63. The retractable rod 64 is fixedly connected to a rotating shaft 65 that rotates with the chassis frame 1, and the top of the rotating shaft 65 is fixedly connected to a differential gear 66. The four sets of planetary gears 63 drive the four sets of differential gears 66 to rotate linearly through the rotating shafts 65 on the four electric telescopic rods 64. The inner side of the differential gear 66 is engaged with a gear ring 67 that is fixedly matched with the material placement table 3. The four sets of differential gears 66 drive the wheel hub in a positioned state on the material placement table 3 to perform a linear transposition operation through the gear ring 67, so as to perform a circular drilling operation on the wheel hub;

[0043] A ring-shaped recess 12 is provided on one side of the loading platform 3 close to the gear ring 67, which slides with the protrusion 61 and serves as a rotational support for the loading platform 3 and the gear ring 67 to prevent the loading platform 3 from being tilted or stuck due to the downward pressure of the wheel hub. The loading platform 3 is provided with an identification scale groove for placing the automobile wheel hub.

The discharge port of the high-pressure suction pump 71 is connected to a threaded pipe 73 that is telescopically matched with the electric lifting arm 13, and is connected to the cleaning bucket 17 through a one-way valve. The iron chips adsorbed in the two groups of suction racks 72 then pass through the two threaded pipes 73 in turn to reach the two groups of cleaning buckets 17, completing the cleaning and storage operation of the iron chips.

[0045] The outer side of the cleaning barrel 17 is connected to a cleaning port 74 with a baffle plate 75, and an extrusion cylinder 76 is embedded in the bottom of the cleaning barrel 17, and an extrusion head 77 is fixedly connected to the extrusion cylinder 76 to slide with the cleaning barrel 17. When there is a large amount of iron filings in the two groups of cleaning barrels 17, the two extrusion cylinders 76 are controlled to drive the two groups of extrusion heads 77 to extrude the iron filings in the two groups of cleaning barrels 17 into cakes from bottom to top, and then the baffle plates 75 on the two groups of cleaning ports 74 are opened, and the iron filings squeezed into cakes in the two groups of cleaning barrels 17 are taken out from the two groups of cleaning ports 74, completing the cleaning work of the iron filings during the drilling of the wheel hub by the drill bit.

[0046] The working principle of a vehicle wheel hub processing device is as follows: first, refer to the marking scale groove and place the wheel hub to be processed on the material loading platform 3, and after it is located between the three sets of outer clamping seats 48 and inner clamping seats 56, first control the three first electric push rods 44 to start and drive the three lower gears 43 to move inward synchronously to the meshing part at the lower end of the double gear 42, then control the double-headed motor 41 to start and the meshed double gear 42 drives the three lower gears 43 to rotate synchronously, and the three lower gears 43 drive the three first electric push rods 44 to move inward synchronously. The lower threaded sleeves 46 on the three lower threaded rods 45 move inward synchronously therewith, and the three groups of lower threaded sleeves 46 drive the outer clamping seats 48 on the three long support plates 47 to move inward toward the outer ring of the wheel hub until the clamping grooves 57 on the three groups of outer clamping seats 48 clamp the outer ring of the wheel hub, and the three groups of anti-skid pads 10 and anti-skid heads 11 tighten the outer end of the wheel hub in an anti-skid manner. Then, the double-headed motor 41 is first controlled to pause, and then the three first electric push rods 44 are controlled to close and drive the three lower gears 43 to move outward synchronously to disengage the meshing portion at the lower end of the double gears 42 to the initial position.

[0047] After the first gear 42 is engaged with the first gear 42, the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42, and the second gear 42 is engaged with the first gear 42,

[0048] Then, the electric lifting arm 13 is controlled to drive the components on the electric guide rail frame 14 to move up and down as a whole, and the electric guide rail frame 14 then drives the lifting cylinder 15 and the drill bit on the drive motor 16 to move back and forth as a whole, until the drill bit displacement is adjusted to the first drilling point on the wheel hub in the positioning state, and then the lifting cylinder 15 is controlled to drive the drill bit on the drive motor 16 to move down, while the drive motor 16 also drives the drill bit to drill the first drilling point on the wheel hub. After the drilling operation of the first drilling point on the wheel hub is completed, the drill bit on the drive motor 16 is controlled to reset, and the four electric telescopic rods 64 are controlled to open and drive the four planetary gears 63 to move down synchronously to the meshing part of the toothed disc 62, and then the double-headed motor 41 is controlled to open again and drive the four planetary gears 63 to move down synchronously to the meshing part of the toothed disc 62 through the meshing The star gears 63 rotate synchronously, and the four planetary gears 63 drive the four differential gears 66 to rotate synchronously through the rotating shafts 65 on the four electric telescopic rods 64. The cam 61 and the recess 12 provide rotational support for the material loading platform 3. Then, the four differential gears 66 drive the wheel hub in the positioning state on the material loading platform 3 to rotate linearly through the gear ring 67 until the wheel hub on the material loading platform 3 rotates and transposes to the second drilling point. Similarly, the drill bit on the drive motor 16 is controlled to be back in place and drill the second drilling point on the wheel hub. This process is repeated and repeated until all the drilling points on the wheel hub are drilled. The double-headed motor 41 is first controlled to be turned off, and then the four electric telescopic rods 64 are controlled to be turned off and the four planetary gears 63 are driven to move up synchronously to disengage the meshing portion of the toothed disc 62 to the initial position.

[0049] During this period, first control the two sets of high-pressure suction pumps 71 to open and apply strong negative pressure suction to the two sets of suction racks 72. Under the action of negative pressure suction, the iron chips generated in the hub drilling area are strongly adsorbed by the two sets of suction racks 72, and then the adsorbed iron chips are discharged from the two threaded tubes 73 to the extrusion heads 77 in the two sets of cleaning barrels 17. After the iron chips are adsorbed to a certain amount, first control the two extrusion cylinders 76 to open, and drive the extrusion heads 77 to extrude the iron chips that have reached the cleaning barrel 17 from bottom to top into a cake shape, then open the baffle plate 75 on the cleaning port 74, and take out the cake-shaped iron chips that fall as the extrusion head 77 resets, thereby completing the collection and cleaning of iron chips at the hub drilling site by the drill bit.

The specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.
