The pull rod is fixed in the fixing hole of the support seat, and the positioning column is sleeved on the upper part of the pull rod. The key point is to add a detection step above the middle support step of the pull rod, whose outer diameter is larger than the aperture size of the wheel hub center hole before the bolt groove is pulled, but smaller than the aperture size of the wheel hub center hole after the bolt groove is pulled. The length of the detection step is 5-20mm. Because the size of the detection step is larger than the aperture size of the wheel hub center hole before the bolt groove is pulled, once the wheel hub center hole is not bolted, the wheel hub center hole cannot be inserted into the detection step of the pull rod, and the wheel hub cannot be in the normal installation position, so as to discover processing errors and prevent the outflow of unqualified products and affect the assembly of the next process.

The support spring 105 provides support for the positioning seat 106, and the positioning seat 106 provides support for the wheel hub. When in use, the bearing is placed in the support cylinder 103, and the wheel hub is placed on the top of the positioning seat 106. The wheel axle is passed through the positioned wheel hub and bearing, and finally another bearing is placed. After placement is completed, the pressure plate 109 and the pressure seat 110 are pushed downward by an external hydraulic device, and the pressure cylinder 104 is driven to move downward at the same time. The bearing above the wheel hub is pressed by the pressure cylinder 104, so that the wheel hub, bearing and wheel axle are assembled. When pressing down, the elastic force provided by the support spring 105 to the positioning seat 106 makes the wheel hub on the top of the positioning seat 106 float and position, so as to avoid the wheel hub being offset and damaged when pressing down.

When in use, the bearing is placed in the support cylinder 103, and the wheel hub is placed on the top of the positioning seat 106, and the wheel axle is passed through the positioned wheel hub and bearing, and finally another bearing is placed. After placement is completed, the pressure plate 109 and the pressure seat 110 are pushed downward by an external hydraulic device, and the pressure cylinder 104 is driven to move downward at the same time. The bearing above the wheel hub is pressed by the pressure cylinder 104, so that the wheel hub, bearing and axle are assembled. When pressing down, the elastic force provided to the positioning seat 106 by the support spring 105 makes the wheel hub on the top of the positioning seat 106 float and position, avoiding the displacement of the wheel hub and causing damage to the wheel hub when pressing down, and solving the problem that the assembly tool of the wheel hub is not convenient for simultaneously installing the bearings on both sides of the wheel hub when in use. After assembling the bearing on one side, the wheel hub needs to be turned over and the bearing on the other side needs to be installed, resulting in a reduction in assembly speed.
