Abstract
A kind of hollow roller simple in structure, including hollow roller, it is characterised in that：The hollow roller is provided at both ends with housing, the housing is cylinder, it is provided with jackscrew in the top wire hole of housing, jackscrew is pressed on across top wire hole on the hollow roller, and the housing is threadedly coupled with circular mounting disk, and through-hole is provided in mounting disc, interior expansion core is bolted across the through-hole with mounting disc, the interior expansion core is provided with mounting hole, and expansion set is provided between interior expansion core and hollow roller inner wall, and the expansion set is stuck in mounting disc.The utility model is simple in structure, easy to assembly, does not need special installation tool, and all components can be individually replaced, it can be achieved that reusing, and the delivery cycle is short, at low cost, and realize production domesticization.
Description
Technical field
The utility model is related to roller technical field, more particularly to a kind of hollow roller simple in structure.
Background technology
In drop stamping field, production line is made of heating furnace, rolling bed, press, robot etc., and solid roller is heating
The important composition part of stove, heating furnace length is about 40 meters, and the transmission of the inside heated components is completely by hollow and solid roller
It realizes.Currently, all solid roller in China can only rely on import, and it is expensive, roller needs dedicated in assembling
Design tool installs laborious, complex process, since the service life of roller only has 1 year or so, so annual cost is very high.This
Utility model while ensureing roller performance the technical problem to be solved is that structure is simplified, and installation is more convenient, and component can
It is individually replaced, reduces cost.
Invention content
The purpose of this utility model is to provide a kind of hollow roller simple in structure.
What the purpose of this utility model was realized in：A kind of hollow roller simple in structure, including hollow roller, it is special
Sign is：The hollow roller is provided at both ends with housing, and the housing is cylinder, and jackscrew is provided in the top wire hole of housing,
Jackscrew is pressed on across top wire hole on the hollow roller, and the housing is threadedly coupled with circular mounting disk, is provided in mounting disc
Through-hole, interior expansion core are bolted across the through-hole with mounting disc, and the interior expansion core is provided with mounting hole, interior expansion core and sky
Expansion set is provided between heart roller inner wall, the expansion set is stuck in mounting disc.
The utility model has the advantages that：It is simple in structure, it is easy to assembly, special installation tool is not needed, all components can
To be individually replaced, it can be achieved that reusing, the delivery cycle is short, at low cost, and realizes production domesticization.
Description of the drawings
Fig. 1 is the structure schematic diagram of the utility model.
Description of the drawings：1- housings；2- mounting discs；Expansion core in 3-；4- mounting holes；5- top wire holes；6- jackscrews；7- hollow rolls
Son；8- bolts；9- expansion sets.
The utility model is described in further detail by example below in conjunction with attached drawing, but following examples is only
The utility model example therein, does not represent right protection range defined by the utility model, the utility model
Rights protection scope is subject to claims.
Specific implementation mode
Example 1
Referring to Fig. 1, a kind of hollow roller simple in structure, including hollow roller 7, it is characterised in that：The hollow roller 7
It is provided at both ends with housing 1, the housing 1 is cylinder, and jackscrew 6 is provided in the top wire hole 5 of housing 1, and jackscrew 6 passes through top wire hole
5 are pressed on the hollow roller 7, and the housing 1 is threadedly coupled with circular mounting disk 2, and through-hole, interior expansion core are provided in mounting disc
3 are connect with mounting disc by bolt 8 across the through-hole, and the interior expansion core is provided with mounting hole 4, interior expansion core in hollow roller
Expansion set 9 is provided between wall, the expansion set 9 is stuck in mounting disc 2.
The interior expansion core has limit plug and the insertion section with endoporus to be made into integration, and the limit plug section is ladder
Shape, trapezoidal limit plug center are provided with mounting hole, the through-hole being connected to mounting hole are provided in insertion section.
Operation principle：The housing is in close contact by machining realization with roller, and housing is machined with top wire hole, and jackscrew is logical
Top wire hole is crossed, jackscrew is tightened and is contacted with roller, realizes external clamping, more securely；The expansion set is spring mechanism, by interior
Expansion core realizes opening and closing, and the contact after opening with the inner wall of roller tightly enables entire expansion set structure to be adsorbed onto roller
On inner wall, mounting hole and transmission axis connection, to realize transmission；Mounting disc is attached to together with interior expansion core, by 4
Hex bolts connects, and housing and mounting disc installation together, realize inside and outside clamping, more securely.
In terms of advantage：It is simple in structure, it is easy to assembly, special installation tool is not needed, all components can be individually replaced,
Recycling can be achieved, the delivery cycle is short, at low cost, and realizes production domesticization.
