Document Type and Number:
Japanese Patent JPS6018930
Kind Code:
B2
Abstract:
An apparatus for clamping and centering bodies during rotation for balancing with a body receiving plate which is mounted on a spindle and which has a pair of concentric flexible rings or gaskets mounted on the upper surface thereof to define, when the body rests on the rings, a vacuum chamber from which air is removed to lock the body in place by channels which extend through the plate and communicate with the vacuum chamber. A housing extends about and is connected to the spindle by bearings with the space between the housing and spindle communicating with the vacuum chamber and with a connection extending through the housing for removing air from the vacuum chamber. Extensions of the spindle and vent holes between the housing space and the bearing prevent a vacuum from being developed in the area of the bearings.
