Size difference it is a little bigger can only replace a whole set of ringfeder mandrel, since wheel hub has many different central hole sizes, scene
It needs to make the ringfeder mandrel of many specifications, on the one hand increases production cost, on the other hand also increase field management difficulty, replacement
It when mandrel, finds mandrel and dismounting mandrel delays many times, reduce production efficiency, therefore we are a kind of new it is necessary to design
The positioning core axle structure of type solves problem above.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and the positioning core axle that the one kind proposed is novel
Structure.
To achieve the goals above, present invention employs following technical solutions:
A kind of novel positioning core axle structure, including pedestal, elastic expansion-sleeve, locating piece, gag lever post, fixing bolt, hydraulic cylinder,
Piston rod, it is characterized in that: pedestal is set as stepped construction, which is provided with cylinder table and 8 uniformly distributed M12 threaded holes, elastic expanding
Set is made of the uniformly distributed elastomer of 8 valves, and outside is set as staged hollow structure, and inside upper part is set as pyramidal structure, and is located at bottom
Seat upside, locating piece is set as sector structure, which is provided with a counterbore, on the shoulder of elastic expansion-sleeve, sets on the upside of gag lever post
There is the pyramidal structure to match with elastic expansion-sleeve, be located on the inside of elastic expansion-sleeve, and is equipped with coaxial through-hole, through-hole with pedestal center
Interior to be equipped with fixing bolt, the inside of hydraulic cylinder is equipped with piston rod, and hydraulic cylinder is located at Its lower side, and fixing bolt passes through limit
Bar and pedestal are threadedly coupled with piston rod.
Preferably, between the eight valve elastomers there are certain interval, unthreaded hole, one are equipped on every valve elastomer
A M10 threaded hole, a shoulder.
Preferably, the fan angle of the locating piece is consistent with elastomer angle, and internal diameter and cylinder table diameter are equal,
Its outer diameter is designed according to different central hole sizes.
Compared with the prior art, the present invention has the following advantages:
1, elastic expansion-sleeve, gag lever post have versatility, it is only necessary to design and buying different size locating piece, reduce buying at
This, facilitates field management；
2, elastic expansion-sleeve is able to drive locating piece distending and Self-resetting together, and the locating piece of every kind of specification is enable adaptively to install
A certain range of central hole size；
3, it when switching the product of different centre bore specifications, does not need to replace a whole set of positioning core axle structure, it is only necessary to locating piece is replaced,
It is convenient and efficient.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
It referring to Fig.1-2, is a kind of novel positioning core axle structure, including pedestal 1, elastic expansion-sleeve 2, locating piece 3, gag lever post
4, fixing bolt 5, hydraulic cylinder 6, piston rod 7, it is characterized in that: pedestal 1 is set as stepped construction, which is provided with 11 He of cylinder table
8 uniformly distributed M12 threaded holes 12, elastic expansion-sleeve 2 are made of the uniformly distributed elastomer 21 of 8 valves, and outside is set as staged hollow structure,
Inside upper part is set as pyramidal structure, and is located at 1 upside of pedestal, and there are certain interval, every valves between the eight valve elastomers 21
The shoulder 213 of M10 threaded hole 212, one of unthreaded hole 211, one is equipped on elastomer 21, locating piece 3 is set as sector structure,
It which is provided with a counterbore 31, on the shoulder 213 of elastic expansion-sleeve 2, the fan angle and elastomer 21 of the locating piece 3
