Make three-jaw more convenient, cost is low, but actual percent defective is very high, the frequency reprocessed is more.Make when high-volume makes part
Obtain cost of spoiled goods to rise, reprocess labor intensity greatly, the quality for product is uncontrollable.
The content of the invention
In order to solve the above problems, the invention provides a kind of pair of cylindrical float clamp mechanism of self-centering, it can facilitate
Stable position is realized on ground, improves efficiency, it is ensured that product quality.
Its technical scheme is such：A kind of pair of cylindrical float clamp mechanism of self-centering, it is characterised in that it includes bottom
It is provided with seat, the base on the outside of mandrel middle base, the mandrel middle base and is provided with annular boss, the mandrel middle base
Bolt is inside installed, the bolt lower end is threadedly coupled on positioning core axle, the bolt and is set with two layers of positioner, described fixed
Position device includes being set in the cylindrical compression spring and axle sleeve of the bolt, is connected by top pressure spring with the mandrel middle base
Activity orientation piece, the cylindrical compression spring is arranged in the axle sleeve lower end, and the activity orientation piece is arranged in the axle sleeve
Upper end, the axle sleeve upper side is provided with annular ramp, and described activity orientation piece one end is provided with what is coordinated with the annular ramp
Inclined-plane, the other end pass through the mandrel middle base.
It is further characterized by, and the base lower end is provided with transition connecting disc, and the transition connecting disc lower end is provided with
Moveable main shaft is provided with through hole, the through hole and draws cap, the main shaft is drawn on cap upper end connection intermediate plate, the intermediate plate
It is provided with multiple hook-shaped arm-ties, the base of the mandrel middle base sidepiece and multiple positioning seats is installed, it is each described fixed
Turnover pressing plate is provided with by bearing pin on the seat of position, the pressing plate sidepiece is provided with the positioning coordinated with the hook-shaped arm-tie
Block, the locating piece is arranged in the hook-shaped groove of the hook-shaped arm-tie；
Dividing plate is provided between positioner described in two layers；
Every layer of positioner includes three activity orientation pieces being evenly arranged.
After structure using the present invention, it would be desirable to which the part of processing is positioned on the annular boss of mandrel middle base, up
Bolt is turned, positioning core axle up mobile extruding cylindrical compression spring is driven, cylindrical compression spring promotes axle sleeve up to move, by
Setting in annular ramp and inclined-plane, promotes activity orientation piece to eject outward, and the double self-centering positioning of realization are withstood from inside parts,
Stable position has been conveniently realized, efficiency has been improved, it is ensured that product quality.
