One) 10 observe the image of the Computer display, after microballoon enters the adsorption orifice of the left clamper, open the left side
Solenoid valve closes the right solenoid valve, and microballoon is adsorbed to from the right clamper on the left clamper, and completion, which is loaded, changes
Position；
Two) 10 adjust the fine motion translation stage, make to withdraw setting position to thereafter；
Three) 10 rotate the differential thread set of the left clamper, begin in the end for keeping the sliding screw core of the left clamper
It is whole contacted with the positioning datum end face in the case of, microballoon center is adjusted to the lateral position reference line；
10 four) on pull the handles of the right side quick-speed jigs, unclamp the right side quick-speed jigs, the left clamper taken out,
It is fixed on being loaded in unit for microballoon machining tool, after the completion of waiting for microballoon overall processing, from the unit that is loaded of microballoon machining tool
It is interior to take out the left clamper；
Five) 10 close the left solenoid valve, microballoon is discharged into designated position, completes the processing of microballoon.
2. microballoon clamping according to claim 1 and localization method, which is characterized in that the adsorption orifice uses trumpet type knot
Structure.
