The first hydraulic push rod 43 drives multiple T-shaped cylindrical rods 442 to move toward the wheel hub through the rectangular plate 441. After the horizontal sections of multiple T-shaped cylindrical rods 442 move to the bottom of the corresponding wheel hub, the operation of the first hydraulic push rod 43 is stopped, and the drive motor 322 is started again. The drive motor 322 drives the lead screw 321 to rotate in the opposite direction. The lead screw 321 drives the support block 33 to descend through the lifting block 323. The support block 33 drives multiple connecting screws 351 to descend through the strip plate 34. After the wheel hub contacts the T-shaped cylindrical rod 442, the wheel hub is supported by the T-shaped cylindrical rod 442, and the multiple connecting screws 351 drive multiple supporting plates 352 and calibration screws 351 to move. The sleeve 353 is separated from the wheel hub and reset downward, and then the first hydraulic push rod 43 is started. The first hydraulic push rod 43 drives the multiple wheel hubs on the upper ends of the multiple T-shaped cylindrical rods 442 to move through the rectangular plate 441. When the multiple T-shaped cylindrical rods 442 contact the second conveying roller 413, the second conveying roller 413 blocks the multiple T-shaped cylindrical rods 442. The rectangular plate 441 continues to move on the multiple T-shaped cylindrical rods 442 and pushes the multiple wheel hubs to the upper ends of the second conveying roller 413. At the same time, the rectangular plate 441 stretches the multiple connecting springs 443. When the multiple wheel hubs are completely moved onto the second conveying roller 413, the second conveying roller 413 conveys the wheel hubs, and the first hydraulic push rod 43 drives the rectangular plate 441 to reset. The rectangular plate 441 drives the multiple T-shaped cylindrical rods 442 and the multiple connecting springs 443 to reset. Then repeat the previous wheel hub conveying steps until all the wheel hubs are conveyed and the conveying is completed.
