Description
Technical field
The invention belongs to mechanical equipment of steel rolling technical field more particularly to a kind of hot-rolled strip roll bearing seat liner plate symmetries
Detection method further relates to a kind of detection auxiliary device for this method.
Background technique
In rolling mill for hot rolled planks and strips, the symmetry with roll bearing seat assembly rear lining plate is affected to mill stiffness, according to setting
Meter requires, and the symmetry of liner plate is on the basis of inner hole of bearing seat axis, and under bearing block belt roller state, inner hole can not be direct
Measurement, therefore the measurement of belt roller bearing support lining plate symmetry becomes difficult point.Since laser tracker precision is high, small and exquisite, portable etc.
Advantage, is increasingly used in metallurgical equipment bulk accuracy detection, and the difficult point and emphasis of laser tracker application are
The determination of the foundation of coordinate system, especially coordinate origin.Symmetry is carried out to bearing support lining plate using laser tracker at present
There are two ways to measurement: 1) traditional belt roller measures indirectly: the parts such as backing roll, bearing are not dismantled, will be direct with roll bearing seat
Detection place is fallen within, does not adjust the position of backing roll and bearing block, bearing, utilizes laser tracker detection liner plate face to be checked and branch
Runner outer circle, establishes coordinate system on the basis of supporting roll axis, analyzes and calculate the symmetry in face to be checked, but due to the axis of roller system
It holds seat, bearing, backing roll roll neck to be gap-matched, gap and is greater than 0.5mm, the position for supporting roll axis is difficult to determine, institute
The liner plate symmetry error for surveying bearing block is larger, causes rolling working condition lower support roll roller system to form the excessive angle of the crossing, reduces
Mill stiffness；2) it directly measures: backing roll, bearing etc. is dismantled, exposed inner hole of bearing seat (is surveyed at this time using on the basis of inner hole
Amount is overlapped with design basis), detection two side plate of bearing block opens a grade size, flatness, the depth of parallelism, symmetry, due to hot rolled plate
The backing roll roller system of hoop mill generallys use band case (bearing block) and is ground, and dismantles backing roll and assembly time is long, to continuous production
Adverse effect is brought, the efficiency of detection reduces, if increasing standby roller amount (containing bearing block), increased costs are less economical.
Summary of the invention
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of hot-rolled strip roll bearing seat liner plate is symmetrical
