The effect of centering；
Equipped with small sealing ring between pressure plunger described in the utility model and fixture axis body.
Equipped with large sealing packing ring between elastic thin-wall described in the utility model set and fixture axis body.
This utility model is easy to use, and fixture axis body is arranged on the headstock of cylindrical grinder, it is also possible to be arranged on
On the main shaft of lathe, during work, sleeve workpiece is sleeved on elastic thin-wall and puts, then screw pressurization with spanner
Screw, forcing screw promotes pressure plunger to move forward by steel ball, squeeze pressure Transfer Medium, and pressure passes
Pass medium by external force extrude after in dielectric cavity bad student's pressure, force the cylindrical elastomer part that elastic thin-wall overlaps
With time delay radial direction dilatating and deformable, thus reach Workpiece clamping and self centering effect；Workpiece adds
Work complete reverse rotation forcing screw, reduces the pressure in dielectric cavity, the cylindrical elastomer part of elastic thin-wall set
Radially resile, can release and workpiece is stepped up；When pressure transmission medium deficiency in dielectric cavity,
By rotating ftercompction screw, dielectric cavity can be carried out auxiliary pressurized effect.
