Abstract
It is of the present utility model that a kind of auxiliary centering chuck, including axle sleeve be provided, internal point, scroll chuck, the scroll chuck is installed in the axle sleeve, the axle sleeve back side is provided with the internal point；The center of circle of the scroll chuck inner circle is set on the same axis with the internal point center of circle；An axle sleeve is respectively inserted at roll both ends before work, and roll is fixedly clamped using scroll chuck；Scroll chuck has certralizing ability to roll, it is ensured that the centring hole of roll and the internal point of auxiliary centering chuck are on the same axis；During roll works, the internal point of axle sleeve instead of the operating position of the centring hole of original roll, and the structure that abrasion produces deviation is changed into internal point, and need to only dismantle Lower shaft sleeve during reparation repairs to internal point, axle sleeve is very light relative to roll, can easily move to reparation position and carry out centering reparation.
Description
Technical field
It the utility model is related to a kind of auxiliary centering chuck.
Background technology
Cold-rolling mill pulls stainless steel plate using motor, is exerted a force to jointly using the load bearing roller of cold-rolling mill, working roll
On two faces of stainless-steel sheet, the size realization by changing two roll seams rolls out the stainless steel plate of different-thickness
Purpose；For the roll of cold-rolling mill through using after a while, the centring hole of roll produces bias because of not stopping to wear, and will cause not
The thickness of rust steel plate differs, or even waste product occurs, and this just needs to disassemble working roll, carries out centering reparation, could continue
Use, roll weight needs to hang to machine is repaired, intermediate demand is through space by tens jin to hundreds of jin after being dismounted
Car is carried out, and is returned working position through traveling crane again after the completion of reparation and is installed, is inconvenient.
The content of the invention
The purpose of this utility model is to overcome drawbacks described above, there is provided a kind of auxiliary centering chuck, be instead of in roll work
To abrasion caused by centring hole, auxiliary centering chuck need to only be removed to reparation, the efficiency of raising during reparation.
The utility model uses following technical scheme：
A kind of auxiliary centering chuck, including axle sleeve, internal point, scroll chuck, the three-jaw card is installed in the axle sleeve
Disk, the axle sleeve back side are provided with the internal point；The center of circle of the scroll chuck inner circle is located at same axis with the internal point center of circle
On.
An axle sleeve is respectively inserted at roll both ends before work, and roll is fixedly clamped using scroll chuck；Scroll chuck is to rolling
Roller has certralizing ability, it is ensured that the centring hole of roll and the internal point of auxiliary centering chuck are on the same axis.
Preferably, the inner bottom part center position in axle sleeve is additionally provided with thimble, and the bottom center of circle and the internal point of the thimble are justified
The heart, the center of circle three of scroll chuck inner circle are set on the same axis.
An axle sleeve is respectively inserted at roll both ends before work, while the thimble of axle sleeve is headed into the centring hole of roll；Utilize three
Roll is fixedly clamped by dog chuck；Thimble and scroll chuck all have certralizing ability to roll, more accurately by pair of roll
The internal point of mesopore and auxiliary centering chuck is on the same axis.
During roll works, the internal point of axle sleeve instead of the operating position of the centring hole of original roll, and abrasion produces inclined
The structure of difference is changed into internal point, and need to only dismantle Lower shaft sleeve during reparation repairs to internal point, and axle sleeve is relative to roll ten
It is point light, it can easily move to and repair position and carry out centering reparation.
The utility model is simple in construction, low manufacture cost, easy to use, and operating efficiency is effectively improved.
Brief description of the drawings
Fig. 1 is overall schematic of the present utility model.
Fig. 2 is the utility model upward view.
Embodiment
In order that the purpose of this utility model, technical scheme are clearer, below in conjunction with drawings and Examples, to this practicality
It is new to be further described：
A kind of auxiliary centering chuck as shown in Figure 1 and Figure 2, including：Axle sleeve 1, internal point 2, scroll chuck 3.
Scroll chuck 3 is installed, the back side of axle sleeve 1 is provided with internal point 2 in axle sleeve 1；The center of circle of the inner circle of scroll chuck 3, centering
The center of circle of hole 2 is set on the same axis.
An axle sleeve 1 is respectively inserted at roll both ends before work, and roll is fixedly clamped using scroll chuck 3；Scroll chuck 3 is right
Roll has certralizing ability, it is ensured that the centring hole of roll and the internal point 2 of auxiliary centering chuck are on the same axis.
Preferably, the inner bottom part center position in axle sleeve 1 is provided with thimble 4, the bottom center of circle of thimble 4 and the center of circle of internal point 2,
The center of circle three of the inner circle of scroll chuck 3 is set on the same axis.
An axle sleeve 1 is respectively inserted at roll both ends before work, while the thimble 4 of axle sleeve 1 is headed into the centring hole of roll；Utilize
Roll is fixedly clamped by scroll chuck 3；Thimble 4 and scroll chuck 3 all have certralizing ability to roll, more accurately by roll
Centring hole and auxiliary centering chuck internal point 2 on the same axis.
During roll works, the internal point 2 of axle sleeve 1 instead of the operating position of the centring hole of original roll, and abrasion produces
The structure of deviation is changed into internal point 2, and need to only dismantle Lower shaft sleeve 1 during reparation repairs to internal point 2, axle sleeve 1 relative to
Roll is very light, can easily move to reparation position and carry out centering reparation.
It is described above, only it is the utility model preferred embodiment, not technical scope of the present utility model is appointed
What is limited, therefore every any trickle amendment made according to technical spirit of the invention to above example, equivalent variations are with repairing
Decorations, still fall within the scope of protection of the utility model.
