[0015] The present invention performs milling and grinding operations on the wheel hub by providing a processing table assembly. After milling on the first base is completed, the wheel hub is moved to the top of the second base by rotating the fixed wheel and the transposing wheel.

[0026] Further, such as Figure 3 As shown, the processing table assembly 4 includes two fixed wheels 41 rotatably connected to both sides of the inner cavity of the processing box 1, and a transposition wheel 43 is provided at one end of the two fixed wheels 41 away from the processing box 1. The end of the fixed wheel 41 close to the transposition wheel 43 is rotatably connected to two connecting plates 42 at equal distances, and the other end of the connecting plate 42 is rotatably connected to the transposition wheel 43. The first operating assembly 45 and the second operating assembly 46 are respectively provided on the upper and lower sides between the two transposition wheels 43, and the positions of the first operating assembly 45 and the second operating assembly 46 correspond to each other up and down.

[0029] Further, such as Figure 4 and Figure 5 As shown, the inner cavity of the first base 451 is movably connected with a pressure ring 457, and the upper part of the inner cavity of the first base 451 is fixedly connected with a limiting ring 458. A groove is provided on one side of the outer surface of the pressure ring 457, and the limiting ring 458 is movably connected with the groove on the outer surface of the pressure ring 457. According to the specific specifications and dimensions of the wheel hub, the position of the pressure ring 457 moving up and down is adjusted by the limiting ring 458.

A plurality of fastening springs 4510 are arranged at the bottom end of the pressure ring 457, and the plurality of fastening springs 4510 are arranged in a ring array. When the wheel hub is squeezed and fixed by the pressure ring 457, its pressure is enhanced by the fastening springs 4510.

[0030] Further, such as Figure 4 and Figure 5As shown, the bottom end of the first base 451 is fixedly connected to the first hydraulic cylinder 456, the inner cavity of the pressure ring 457 is movably connected to the first piston 4511, the bottom end of the first piston 4511 is fixedly connected to the connecting block 4512, the output end of the first hydraulic cylinder 456 is fixedly connected to the bottom end of the connecting block 4512, the pressure ring 457 is sleeved on the lower part of the outer surface of the connecting block 4512, when the protruding end of the first hydraulic cylinder 456 is shortened to the shortest, the pressure ring 457 is fixed in the inner cavity of the first base 451 through the connecting block 4512, after the first operating component 45 is flipped over, when the wheel hub is fixed between the first operating component 45 and the second operating component 46, when the protruding end of the first hydraulic cylinder 456 is extended, the first piston 4511 is pushed to perform piston movement in the inner cavity of the pressure ring 457, after the pressure ring 457 is separated from the extrusion of the connecting block 4512, the pressure ring 457 is provided with pressure through the tightening spring 4510, so that it squeezes and fixes the wheel hub to the top of the second operating component 46.

[0031] Further, such as Figure 4 , Figure 5 and Figure 6 As shown, the second operating component 46 includes a second base 461 arranged on the other side between the two transposition wheels 43, a second hydraulic cylinder 463 is fixedly installed at the bottom end of the second base 461, a second sealing plate 464 is fixedly connected to the top end of the second base 461, and a second piston 465 is movably connected to the inner cavity of the second base 461.

After the first operating component 45 is flipped, the wheel hub is located between the first base 451 and the second base 461.

[0035] The present invention also provides a working method of the automobile wheel hub milling processing device, comprising the following steps: Step 1: First, place the wheel hub to be processed on the top of the first base 451. According to the specific specifications and dimensions of the wheel hub, push the clamp block 32 through the third hydraulic cylinder 34, and clamp and fix the wheel hub through the jaws 33 on the two clamp blocks 32. After the fixation is completed, start the milling device 7, and perform milling operation on the wheel hub through the milling device 7. During the milling process, the milling device 7 is moved through the slide rail 5 and the first cylinder 6. After one side of the milling is completed, start the first motor 10, and the first motor 10 rotates the fixed wheel 41. When the fixed wheel 41 rotates 90 degrees, it drives the two connected wheels to rotate. The connecting plate 42 and the transposition wheel 43 rotate, and the direction of the connecting plate 42 remains unchanged, so that the first operating component 45 moves downward while the direction remains unchanged. The movement of the first operating component 45 provides space for turning over the wheel hub. When the first operating component 45 moves downward, the second motor 11 is started, and the support frame 31 is driven to rotate by the second motor 11 to turn over the wheel hub fixed between the two clamping blocks 32. After the turning over is completed, the output end of the first motor 10 rotates in the opposite direction, so that the first operating component 45 is reset to support the wheel hub, and then the milling operation on the other side is performed; Step 2: After the double-sided milling of the wheel hub is completed, add fluid abrasive to the inner cavity of the second base 461, then start the first motor 10 again, and the output end of the first motor 10 rotates 180 degrees in the positive direction, so that the second operating component 46 moves upward and the direction remains unchanged. After the second operating component 46 moves to the top of the first operating component 45, the extended end of the third hydraulic cylinder 34 contracts, driving the two clamping blocks 32 to move to both sides, and the wheel hub is placed on the top of the second base 461. After the placement is completed, the output end of the first motor 10 is then rotated 180 degrees in the opposite direction, so that the first operating component 45 and the second operating component 46 return to their original positions, and then the transposition motor 453 is started, and the first bevel gear 454 and the second bevel gear 455 are meshed and rotated by the transposition motor 453, and the first operating component 45 is flipped 180 degrees; Step 3: After the first operating component 45 is flipped over, the first hydraulic cylinder 456 is started. The extended end of the first hydraulic cylinder 456 pushes the first piston 4511 and the connecting block 4512 to move in the inner cavity of the pressure ring 457. When the pressure ring 457 is separated from the extrusion of the connecting block 4512, the pressure ring 457 is pushed downward by the tightening spring 4510 to provide thrust to the wheel hub, so that the wheel hub is fixed on the top of the second base 461, so that a fluid abrasive channel is formed between the pressure ring 457, the wheel hub and the inner cavity of the second base 461. The first sealing plate 459 and the second sealing plate 464 have a certain width and can be suitable for a variety of wheel hubs of different specifications and sizes. After the wheel hub is fixed between the first base 451 and the second base 461, the first sealing plate 459 and the second sealing plate 464 support the wheel hub while ensuring the tightness of the connection; Step 4: After the fluid abrasive channel is formed, the second hydraulic cylinder 463 is started, and the first hydraulic cylinder 456 continues to extend. The first hydraulic cylinder 456 drives the first piston 4511 to perform piston movement in the inner cavity of the pressure ring 457, and the second hydraulic cylinder 463 drives the second piston 465 to perform piston movement in the inner cavity of the second base 461. The piston movement of the first piston 4511 and the second piston 465 promotes the fluid abrasive to flow in the inner cavity of complex structures such as through grooves and holes generated after the wheel hub is milled. The fluid abrasive is continuously ground under the action of pressure to achieve polishing and grinding of the inner walls of complex structures such as through grooves and holes.
