According to the working condition of the precision positioning central spindle, when a workpiece is installed on the elastic sleeve, the pressurization inner hexagon screws are screwed into the elastic sleeve, and a liquid synthetic material is pressurized through an end head; when a liquid synthetic material cavity is sealed, the pressure borne by the liquid synthetic material is uniformly acted on the elastic sleeve according to the incompressibility of liquid and the principle that the liquid can transfer pressure uniformly in all the directions, the elastic sleeve generates radial elastic deformation and makes cylindrical contact with the workpiece to enable the workpiece to be accurately positioned and reliably clamped. When a screw plunger is screwed out, the elastic sleeve returns to the original position under the action of elasticity, and the workpiece is loosened. Through the improvement on the machining method of the elastic sleeve, the central spindle body and the pressurization inner hexagon screws, the precision of the positioning central spindle is improved remarkably, and the workpiece can be prevented from being pinched in the using process.
