It is equipped with coaxial through-hole, and is equipped with fixing bolt in through-hole, mandrel pedestal is equipped with hydraulic cylinder far from the side of ringfeder mandrel,
And the inside of hydraulic cylinder is equipped with piston rod, fixing bolt passes through mandrel pedestal far from one end of gag lever post, and remote with piston rod
One end of chaotropic compressing cylinder is connected, and piston rod is equipped with the connection spiral shell matched with fixing bolt far from one end of hydraulic cylinder
Hole.
Preferably, the ringfeder mandrel includes the first elastic expansion-sleeve and the second elastic expansion-sleeve, the first elastic expansion-sleeve and second
The center of elastic expansion-sleeve is equipped with conical internal cavity, and two groups of conical cavity shapes are identical and mutually symmetrical with.
Preferably, the mandrel pedestal and gag lever post are respectively equipped with the first tapered portion and second close to the side of ringfeder mandrel
Tapered portion, and the first tapered portion and the second tapered portion are matched with the second elastic expansion-sleeve and the first elastic expansion-sleeve respectively.
Compared with prior art, the utility model has the beneficial effects that:
1, using the flexible of hydraulic cylinder inner piston rod, to control moving up and down for gag lever post, thus controllable ringfeder core
The distending of axis and recovery, and the distending degree of elastic expansion-sleeve can be controlled by the lower pan position of gag lever post, are applicable to
Wheel hub in heart pore size difference, it is applied widely, and when the wheel hub of the different central hole sizes of positioning, replacement mandrel is not needed,
It improves work efficiency, and reduces production cost;
2, it is zero with center interporal lacuna after elastic expansion-sleeve distending, realizes precise positioning, ensure that subsequent processing quality;
3, when rubber pad can be moved down with buffer limit bar, shock between the first tapered portion and the second tapered portion, reduction is made an uproar
Sound, while extending the service life of tapered portion.
Detailed description of the invention
Fig. 1 is the maching of Al wheel positioning core axle structural schematic diagram before improving;
Fig. 2 be the utility model proposes a kind of improved the maching of Al wheel positioning core axle.
In figure:1 mandrel pedestal, 2 fixing bolts, 3 ringfeder mandrels, 31 first elastic expansion-sleeves, 32 second elastic expansion-sleeves, 4 limits
Position bar, 5 hydraulic cylinders, 6 piston rods, 7 first tapered portion, 8 second tapered portion.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of improved the maching of Al wheel positioning core axle, including mandrel pedestal 1, mandrel pedestal 1
Upside is equipped with ringfeder mandrel 3, and ringfeder mandrel 3 includes the first elastic expansion-sleeve 31 and the second elastic expansion-sleeve 32, the first elastic expansion-sleeve 31
It is equipped with conical internal cavity with the center of the second elastic expansion-sleeve 32, two groups of conical cavity shapes are identical and mutually symmetrical with, ringfeder mandrel
3 sides far from mandrel pedestal 1 are equipped with gag lever post 4, and mandrel pedestal 1 and gag lever post 4 are respectively equipped with close to the side of ringfeder mandrel 3
First tapered portion 7 and the second tapered portion 8, and the first tapered portion 7 and the second tapered portion 8 respectively with the second elastic expansion-sleeve 32 and first
Elastic expansion-sleeve 31 matches, and the center of gag lever post 4, ringfeder mandrel 3 and mandrel pedestal 1 is equipped with coaxial through-hole, and in through-hole
