Rolling element center offers mounting hole, is connected with interior installing ring by several connectors in installation is empty, and interior installation circle center is used
In passing through workpiece, the clamping device for clamping workpiece is installed on interior installing ring.
Compared with the prior art, the utility model has the advantages that：
The first, by the compound action of outer rolling body and clamping device can clamping different-diameter workpiece so that applicability
It improves, so that the utility value of this combination clamping device is bigger, improves the market competitiveness；
The second, outer rolling body and clamping device are all that can be manufactured with parts processing simultaneously, reduce manufacture difficulty and processing
Cost；
Third, interior installing ring and outer rolling body are provided separately, and avoid causing because needing the ring inside and outside simultaneous processing two
Precision after manufacturing procedure trouble, reduction processing cost, and interior installing ring are individually processed is higher, and the circle that edge surrounds is more smart
Really, the edge of installing ring interior in this way can be used to be used as benchmark in CT scan detection, and reduction causes because of primary standard substance error
The big phenomenon of measurement error.
The further advantage, target and feature of the utility model will be partially reflected by the following instructions, and part will also pass through
Research and practice to the utility model and be understood by the person skilled in the art.
