The content of the invention
The utility model, in order to reduce labor strength, shortens service working time for the deficiency of above-mentioned technology, carries A kind of high workload efficiency, there is provided thin-wall part cylindricalo grinding hydraulic pressure automatic fixture.
The technical solution of the utility model is:Thin-wall part cylindricalo grinding hydraulic pressure automatic fixture, including L-type base, set respectively The hydraulic structure and tension mechanism in L-type base both sides is put, the tension mechanism includes mandrel;It is arranged on mandrel center drilling Place, for connecting the pull bar of hydraulic structure;The front end of pull bar connects conehead by simultaneously cap, in the mandrel and the outside footpath of conehead Rubber radial spring is provided with face, the outer radial face of rubber radial spring arranges double end blooming expanding sleeve, and the double end is opened The front and back end of flower ringfeder is mutually equipped with the conehead and the frustum on mandrel.
Further, the hydraulic structure includes being connected to the gusset piece of L-type base side, is connected to gusset piece side Cylinder body, is connected to the cylinder seat of cylinder body side;Piston is provided with the oil cylinder body, piston is connected with piston rod, the work Stopper rod is connected through gusset piece and L-type base with pull rod screw.
Further, helical spring is additionally provided with the pull bar, the two ends of the helical spring are contradicted in mandrel and cone Between head.
Further, the mandrel is multidiameter, and on the little axle lateral surface in front end butterfly spring, the butterfly spring are provided with Contradict between mandrel and conehead.
Compared with prior art, the beneficial effects of the utility model are:
1st, tension mechanism is clamped using hydraulic mechanism, need to only stirs the folder that hydraulic selector is capable of achieving cylinder thin-wall part Tightly, non-cutting time is substantially reduced, improves operating efficiency, reduce labor strength.
2nd, expansion sleeve is designed using double end blooming expanding sleeve, while being additionally arranged butterfly spring and rubber footpath inside tension mechanism To spring, it can be ensured that front end, middle part, the rear end of double end blooming expanding sleeve all has certain expanding force, it is to avoid traditional tensioner machine The situation of structure tensioner blooming expanding sleeve one end, can cause cylinder thin-wall part expanding force uniformity on axial length, carry significantly The high stability of such tension mechanism.
