The technical scheme of the employing of the utility model is following:
On cylindrical shell, the expansion anchor clamps are fixed on the rotary main shaft that exposes an end outside cylindrical shell through pressing plate is coaxial rotary main shaft through upper and lower bearings, and columned magnetostriction post is equipped with in rotary main shaft and expansion anchor clamps inside; Be fixed on the rotary main shaft lower end through fixed block; Also be provided with belt pulley on the face of cylinder, rotary main shaft top, the cylindrical shell outside is wound with coil, and the top of magnetostriction post is fixed with the top; It is inner that the expansion anchor clamps are stretched in the top; Fitted in inclined-plane and the inner inclined-plane of expansion anchor clamps on the top, be fixed with the orienting lug of taper in expansion anchor clamps upper end, the impeller endoporus of impeller to be tested is enclosed within expansion anchor clamps outside through orienting lug.
On the face of cylinder of described expansion anchor clamps, have the reed of symmetrical distribution, reed lower end free end, the reed upper end is fixing, and the inclined-plane of the expansion anchor clamps inside that reed is inner cooperates with the inclined-plane on the top.
Under coming directly towards externally coil drive, make the elongation of magnetostriction post and when the top was moved up, reed expanded outwardly, and clamps impeller, when external coil cut off the power supply, the magnetostriction post recovered normal length, drove the top to move down, and impeller is loosened in the reed reinstatement.
The beneficial effect that the utlity model has is:
1) with the cylindrical shell be main not rotary part and with rotary part that rotary main shaft carries between except bearing, have no physics contact, transmit interaction through magnetic field between them;
2) device does not influence the friction means of measuring accuracy;
3) has very fast response speed;
The utility model utilizes the magnetostriction post, realizes the automatic clamping chuck structure that the impeller amount of unbalance is measured automatically.The clamping good reproducibility of this structure also has very high measuring accuracy.
