Description
Technical field
The utility model is related to harness, especially a kind of roll harness component, will be rolled for top be engaged with lathe
Roller top is on lathe.
Background technology
As shown in figure 1, the turning of roll and fine grinding, and for convenience by roll and steel rolling line for convenience
Main shaft is positioned, and the two ends of roll are usually provided with centre bore.Centre bore as Roller Machining process datum hole and dress
Positioning hole and fixing hole during matching somebody with somebody, are generally provided with conical section, innermost end is then provided with screw thread in the outermost end of centre bore
Section.According to the difference of roll model, the coning angle of tapering point is also different.
In the prior art, in the turning of roll and precision grinding process, generally roll is pacified using the chuck and thimble of lathe
On lathe.The size adjustable of chuck, but what the top size of lathe was really fixed, with the increase of roll model, machine
Bed it is top must be replaced by therewith it is larger sized top.In the case of in so, not only buying top expense can make to enterprise
Into white elephant, and machine tool change large scale it is top after, the deadweight of lathe rotating shaft can also increase therewith, and then influence
The machining accuracy of roll.More seriously, it is domestic even to find and size can mutually fit therewith for some ultra-large type rolls
That answers is top, it is necessary to which production needs could be met by changing extraordinary lathe.
Utility model content
The utility model technical issues that need to address are to provide a kind of roller assembly, make its meet in the prior art for
The need for roll with large scale centre bore is processed.
In order to solve the above technical problems, the technical scheme that the utility model is used is：
A kind of roll harness component, it is characterised in that：Including top cap, connecting bolt and inside and outside screw, top cap is set
There is the conical outer wall coordinated with the conical inboard wall of the top cooperation of lathe and with roll centre hole, top cap centre is additionally provided with
One through hole, through hole of the connecting bolt on the top cap is simultaneously engaged with the internal thread of inside and outside screw, and inside and outside screw is also set
It is equipped with the external screw thread being engaged with the thread segment in roll centre hole.
Technical solutions of the utility model further improvement is that：Square is provided with the end face outside of inside and outside screw
Or the boss of regular hexagon.
Technical solutions of the utility model further improvement is that：Regular hexagon is provided with the end face outside of inside and outside screw
Pit.
Technical solutions of the utility model further improvement is that：The coning angle of the outer wall of top cap be 60 ° or 75 ° or
90°。
Technical solutions of the utility model further improvement is that：Bolt head is offered on the inside of the through hole of top cap and allows sky.
By adopting the above-described technical solution, the technological progress that the utility model is obtained is：
Can be realized using the utility model be changed without lathe it is top in the case of, make lathe meet for large scale
The need for the roll of centre bore is processed, not only for enterprise saved a large amount of replacing lathes it is top needed for input, it is more important
Be that of avoiding lathe because change large size it is top and caused by precision reduction.
The utility model or a kind of combined harness, are highly convenient for installation and removal.Meanwhile, pushed up in the utility model
The outer wall of sharp cap can be designed to multiple angles, to meet the demand that is loaded of the roll for different model.
Inside and outside screw in the utility model is designed with multiple structural forms, can preferably adapt to production scene, be easy to
Workman is mounted and dismounted with different instruments, further improves the versatility of this harness.

Embodiment
The utility model is described in further details with reference to embodiment：
As shown in Fig. 2 the utility model is a kind of roll harness component, the centre bore for being mounted in the two ends of roll 30 in advance
On, the roll 30 with large-size centre bore is arranged on the less lathe of size top 20 using the utility model
On.
The utility model includes three components：Top cap 10, connecting bolt 11 and inside and outside screw 12.Top cap 10 is provided with
The conical inboard wall coordinated with lathe top 20 and the conical outer wall coordinated with the centre bore of roll 30.The top centre of cap 10 is also set
A through hole is equipped with, for through connecting bolt 11.In order to prevent bolt head and lathe top 20 from interfering, top cap 10 it is logical
Bolt head is offered on the inside of hole and allows sky.
Connecting bolt 11 is passed through after the through hole, is engaged using its screw thread with the internal thread of inside and outside screw 12, after tightening i.e.
Top cap 10 can be fixed on the centre bore of roll 30.Inside and outside screw 12 is additionally provided with the thread segment 32 with the centre bore of roll 30
The external screw thread being engaged.
As shown in figure 3, being provided with positive four side in the installation of inside and outside screw 12 for convenience, the end face outside of inside and outside screw 12
Shape or regular hexagon boss 121.In use, can be enclosed on using socket wrench or common wrench on boss 121, rotating spanner
