Technical field
The present invention relates to metallurgical technical field of steel rolling, more particularly to a kind of universal mill horizontal roller axial locking device.
Background technology
Edger roll of the universal mill at the top and bottom of the horizontal roller and rolling rolling stock for rolling rolling stock waist is constituted,
Horizontal roller is loaded in upper and lower axle bearing, and edger roll is on edger roll box.Universal mill is to the precision controllings of rolled products, automation
Degree etc. require it is higher, particularly rolling of heavy rail when, have higher requirement to the relative dimensions precision of rolling groove, at this moment to rolling
The axial locking of roller and fixation just seem very important, otherwise will directly influence the precision controlling of heavy rail or even produce just
Often carry out.And in real work, swivel nut, screw cap type screw-threaded coupling device effect it is undesirable, universal mill horizontal roller is frequent
Generation axial float problem, causes rail size irregular fluctuation occur, influences the qualification rate of seamed high-speed steel rail.
The content of the invention
The invention provides a kind of universal mill horizontal roller axial locking device, universal mill horizontal roll shaft can be effectively improved
To locking positioning precision, the axial float that horizontal roller occurs in steel rolling is solved the problems, such as, product qualification rate is improved.
In order to achieve the above object, the present invention is realized using following technical scheme：
Including semi-ring, holding screw, nut, end cap, swivel nut, in the uniform several screwed holes of the end face of swivel nut, end cap spiral shell
Nail is fixed on swivel nut, holding screw is set between nut and end cap, holding screw one end is tightened in nut, and the other end is held out against
On the end face of end cap, and it can be relatively moved between nut and end cap, semi-ring is arranged on the shaft shoulder of horizontal roll on the outside of bearing block
On, when holding screw tightly withstands end cover surface through nut, end cap band movable snail sleeve moves inward, and swivel nut promotes original device
In thrust bearing inner ring, loudspeaker set and four-line column roller bearing inner ring move inward, finally make the same bearing of horizontal roll
Gap is eliminated between seat, is tightly fastened；
During installation locking device, on the shaft shoulder that semi-ring is arranged on to horizontal roll, by spanner by the clamp screw on nut
Clench and press closer end cover surface, laterally rotary nut, end cap band movable snail sleeve moves inward, and swivel nut promotes stopping in original device
Thrust bearing inner ring, loudspeaker set and four-line column roller bearing inner ring move inward, and continue rotary nut, until the outside of nut
Face is firmly withstood on the medial surface of semi-ring, installs semi-ring lock, it is ensured that nut is tightly fastened with semi-ring, cannot come off, and finally makes water
Flat-rolled roller is eliminated with gap between bearing block；When bearing block same level roll is split, the inside side of nut need to only be rotated, by semi-ring
Unloaded from horizontal roll.
The holding screw preferably M24 hexagon socket head cap screws, quantity is 16, but not limited to this specification and quantity.
Compared with prior art, the beneficial effects of the invention are as follows：
It is simple in construction, it is easy to operate, universal mill horizontal roll shaft can be effectively improved to locking positioning precision, horizontal roller is solved
The axial float problem occurred in steel rolling, improves product qualification rate, saving of work and time.
Brief description of the drawings
Fig. 1 is a kind of partial structural diagram of universal mill horizontal roller axial locking device of the invention.
In figure：1. the swivel nut of 5. end cap of horizontal roll 2. semi-ring, 3. holding screw, 4. nut 6.
Embodiment
The embodiment to the present invention is described further below in conjunction with the accompanying drawings：
See Fig. 1, be a kind of partial structural diagram of universal mill horizontal roller axial locking device of the invention, including level
Roll 1, semi-ring 2, holding screw 3, nut 4, end cap 5, swivel nut 6, the present invention carry out structure using the original swivel nut 6 of equipment and changed
Enter, in the uniform several screwed holes of the end face of former swivel nut 6, end cap 5 is fixed on swivel nut 6 with hexagon socket head cap screw, nut 4 and end cap 5
Between set holding screw 3, the one end of holding screw 3 is tightened in nut 4, and the other end is held out against on the end face of end cap 5, and nut 4
It can be relatively moved between end cap 5, semi-ring 2 is arranged on the outside of bearing block on the shaft shoulder of horizontal roll 1, when holding screw 3 is worn
When crossing nut 4 and tightly withstanding 5 surface of end cap, end cap 5 moves inward with movable snail sleeve 6, and swivel nut 6 promotes the thrust shaft in original device
Hold inner ring, loudspeaker set and four-line column roller bearing inner ring to move inward, finally make horizontal roll 1 with gap between bearing block
Eliminate, be tightly fastened.
Following examples are implemented lower premised on technical solution of the present invention, give detailed embodiment and tool
The operating process of body, but protection scope of the present invention is not limited to following embodiments.Method therefor is such as without spy in following embodiments
It is conventional method not mentionlet alone bright.
[embodiment 1] specific implementation method of the present invention is as follows：
The present invention substitutes original using 16 M24 holding screws 3 and set on the premise of former roll and bearing block size is not changed
Swivel nut-nut lock in meter, which is close to, to be connect, and carries out structure improvement to the original swivel nut of equipment 6, is bored in the end surface symmetric of former swivel nut 6
4 length are 20mm M12 screwed holes, and end cap 5 is fixed on swivel nut 6 with 8 M12 hexagon socket head cap screws, nut 4 with end cap 5 it
Between connected with 4 M10 hexagon socket head cap screws, and can be with respect to play between nut 4 and end cap 5.
During installation locking device, on the shaft shoulder that semi-ring 2 is arranged on to horizontal roll 1, by spanner by 16 on nut 4
M24 holding screws 3 tightly withstand the surface of end cap 5, laterally rotary nut 4, and end cap 5 moves inward with movable snail sleeve 6, swivel nut 6
Promote the thrust bearing inner ring in original device, loudspeaker set and four-line column roller bearing inner ring to move inward, continue to rotate spiral shell
Cap 4, until the lateral surface of nut 4 is firmly withstood on the medial surface of semi-ring 2, installs semi-ring lock, it is ensured that nut 4 is close with semi-ring 2
It is fixed, it cannot come off, horizontal roll 1 is eliminated with gap between bearing block.When bearing block same level roll 1 is split, only
The inside side of nut 4 need to be rotated, semi-ring 2 is unloaded from horizontal roll 1.
