Problems solved by technology
In the past processing process, the clamping force of the pneumatic clamping device on the hub bearing is often determined by the experience of the operator, and it is difficult to accurately obtain the clamping force
When the clamping force is insufficient, the hub bearing is prone to offset and slip during the grinding process; when the clamping force is too large, the hub bearing will undergo large elastic deformation, which will affect the grinding accuracy

Description
technical field [0001] The invention relates to a wheel hub bearing grinding clamping force measuring device and a measuring method, belonging to the technical field of mechanical processing. Background technique [0002] The main function of the hub bearing is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important auto part. The internal grinding process of the hub bearing outer ring, as shown in the attached manual Figure 8 shown. The pneumatic clamping device is used to provide clamping force to clamp the hub bearing, and the hub bearing rotates together with the workpiece spindle. During the grinding process, the grinding wheel enters the hub bearing through the feed system for internal plunge grinding. In the past processing process, the clamping force of the pneumatic clamping device on the hub bearing is often determined by the operator's experience, and it is difficult to accuratel...
