Summary of the invention
The technical matters that the present invention solves: a kind of gyro static equilibrium shaking table is provided, the position of Vib. in axial conversion equipment on stage body is arranged on by adjustment, realize the vibration in three directions, top to bottom, left and right, front and rear of Vib., improve efficiency and the Gyro Precision of the correction of gyroscopic equilibrium ring, adapt to the statically balanced correction of multiple gyro product, there is practicality widely.
The technical solution used in the present invention: gyro static equilibrium shaking table, there is stage body, described stage body upper end is provided with sectional fixture and sectional fixture is fixed with gyro, is fixed with axial conversion equipment and realizes the vibration in three directions, top to bottom, left and right, front and rear of gyro by the position of Vib. in the axial conversion equipment of adjustment in the middle part of described stage body lower end.
Wherein, described axial conversion equipment involving vibrations device, mounting disc, bearing, upper bed-plate and lower bottom base, described Vib. to be fixed in mounting disc and mounting disc by being located at the hinge of bearing upper end on bearing, described bearing is provided with banking pin and upper banking pin is placed in below bearing pin, described mounting disc is shaped with brake hole and in upper banking pin insertion brake hole, mounting disc is braked, described bearing lower end is fixed on upper bed-plate, described upper bed-plate is placed on lower bottom base and upper bed-plate center and is connected with upper bed-plate by the rotating shaft be located on lower bottom base, described upper bed-plate right-hand member is provided with lower banking pin and brakes upper bed-plate in lower banking pin inserts on lower bottom base hole.
Further, described sectional fixture lower end and stage body are bolted to connection, and described lower bottom base is fixed in the middle part of stage body lower end and by the vibration of Vib. and drives stage body and gyroscopic vibration.
The present invention's advantage compared with prior art:
1, Vib. can according to user demand adjustment in the position of three axis, realize the vibration of Vib. top to bottom, left and right, front and rear, thus drive stage body and gyroscopic vibration, to eliminate the false gap in gyro ring stand, reduce the impact that bearing friction balances gyro ring stand, realize the static equilibrium of ring stand finally by increase and decrease counterweight, improve Gyro Precision;
2, Vib. three axial installation site conversion is convenient, fast;
3, structure is simple, easy to adjust, improves the efficiency that gyroscopic equilibrium ring corrects, adapts to the static equilibrium needs of most of gyro product, applied widely, just has very high use value.
