[0022] The clamping mechanism 2 includes a mounting frame 201, a mounting plate 207 and a fixing seat 210. The mounting frame 201 is fixed to the top of the clamping platform 1. A hydraulic cylinder 202 is fixed to the top of the mounting frame 201. A combination plate 203 is fixed to one end of the hydraulic cylinder 202.

A punching block 206 is fixed to the surface of the connecting plate 205. An oil injection groove is provided on the inner wall of the punching block 206. The punching block 206 The bottom is connected with a nozzle 218, the mounting plate 207 is fixed to the top of the pressing table 1, the top of the mounting plate 207 is detachably connected with a mounting shell 208, the top of the mounting shell 208 is fixed with a positioning rod 209, the top of the fixing seat 210 is fixed with a second spring 211, the top of the second spring 211 is fixed with a top plate 212, the surface of the top plate 212 is fixed with a support frame 213, the top of the support frame 213 is fixed with a push cylinder 214, and one end of the push cylinder 214 is fixed with a clamping plate 215;

[0023] During the clamping step, the lower bearing is sleeved onto the surface of the positioning rod 209, and then the wheel hub is placed above the positioning rod 209 so that its center is aligned with the center of the lower bearing. At the same time, the wheel hub can be placed on the surface of the top plate 212 so that the wheel hub can be supported to avoid tilting and damage due to lack of support on both sides of the wheel hub during clamping. At the same time, after the push cylinders 214 on both sides are started, the wheel hub can be clamped through the clamping plate 215 to avoid deviation of the wheel hub during the clamping process. After determining the position of the wheel hub, the upper bearing is placed above the wheel hub and aligned with the center point, and then the hydraulic pressure is started. Cylinder 202 causes the combination plate 203 to drive the punching block 206 downward to squeeze the wheel hub and the bearing through the first spring 204 and the connecting plate 205, so that both bearings can enter the inside of the wheel hub and complete the bearing pressing process. Then, the lubricating oil enters the oil filling groove through the infusion mechanism 3, so that the lubricating oil can be sprayed into the wheel hub and the bearing through the nozzle 218, thereby completing the oil filling process, realizing the synchronization of the pressing and oiling of the wheel hub and the bearing, and improving the processing efficiency of the wheel hub. The mounting shell 208 can collect the dripping lubricating oil, which is convenient for cleaning the pressing table 1.
