Patent ID: 8075373

Claim:
A roll grinding apparatus for roll grinding a workpiece, comprising: a clamping device comprising a base defining a first screw hole and a second screw hole therein, a first screw bolt threadedly received in the first screw hole, a second screw bolt threadedly received in the second screw hole, a support comprising a base plate, a first side plate and a second side plate located on opposite ends of the base plate respectively and extending away from a top surface of the base plate, the base plate having a top surface and a bottom surface, the first screw bolt and the second screw bolt being threadedly connected with the bottom surface of the base plate, a first clamping member and a second clamping member coupled to the first clamping member, the first clamping member being rotatably mounted on the first side plate, and the second clamping member being rotatably mounted on the second side plate, the first clamping member and the second clamping member cooperating to clamp the workpiece, a rotary axis of the first clamping member and that of the second clamping member being substantially coaxial; a grinding wheel for grinding the workpiece, the first clamping member and the second clamping member being movable relative to the grinding wheel by movement of the support relative to the base so that the rotary axes of the first and second clamping members are adjusted to be parallel to a central axis of the grinding wheel; a first driver connected with the first clamping member, the first driver being configured for driving the first clamping member rotate around a rotary axis of the first driver; and a second driver connected with the second clamping member, the second driver being configured for driving the second clamping member rotate around a rotary axis of the second driver.
