Abstract
The utility model discloses a check -up detection device of backing roll centre of symmetry and opening degree, its characterized in that includes: check -up detection device is including the two demarcation poles and the the central axis perpendicular to that are the cross the demarcation pipe of two planar complete set tube -shapes in demarcation pole place, mark the pipe and be located the crossing position department of two demarcation poles, wait to detect the plug and follow pass in maring the pipe, the both ends of two demarcation poles all are provided with and are used for the locating hole fixed. Owing to embrace the plug during backing roll initial condition, only unclamp the plug in steel rolling through corresponding support current prescription, consequently the center through the measuring plug has the no change can explain that the centre of symmetry of backing roll has or not deformation. The plug passes through in following the demarcation pipe with the plug when work parking state, because the utility model discloses on demarcation pipe the central axis the time refer to the axis, if take place slight the scratch at the in -process that advances, explain then that the initial centre of symmetry of plug or backing roll has taken place deformation.
Description
Technical field
The utility model relates to a kind of verification pick-up unit, particularly relates to the verification pick-up unit of a kind of backing roll symcenter and opening degree.
Background technology
Must support this plug by multiple spot movable supporting support for the plug that axial length is longer in rolling process, thus after ensureing long-term work can not there is right alignment problem because of deadweight in plug.And in order to realize the object that plug frames is arranged, when plug frames embraces plug, must ensure that plug can be in the center of continuous rolling mill roller pass, but following factor is not in tandem mill pass center after plug can be caused to be embraced: 1. due to plug frames in the fabrication process, each component tolerances exceeds standard, after assembling, when backing roll is held tightly, three backing roll symcenter depart from rolling center; 2. due to plug frames in use because the reason such as stressed, impact, there is uneven wear in bearing pin, copper sheathing, when backing roll is held tightly, three backing roll symcenter depart from rolling center; 3., due to slide plate, the locating piece appearance wearing and tearing of plug frames, when backing roll is held tightly, three backing roll symcenter depart from rolling center; 4., because plug frames three backing rolls are because of situations such as unbalance stress, use different size plugs, backing roll arc-shaped surface can be caused to wear and tear inconsistent, when backing roll holds the plug of part different size tightly, rolling center can be departed from plug center.Need to study a kind of device after device work a period of time for this reason, regularly its center is verified, necessary.
Utility model content
Technical problem to be solved in the utility model is to provide the verification pick-up unit of a kind of backing roll symcenter and opening degree, compact conformation, whether slight distortion can occur inspection center easily.
For solving the problems of the technologies described above, the technical solution of the utility model is: the verification pick-up unit of a kind of backing roll symcenter and opening degree, its innovative point is to comprise: described verification pick-up unit comprises two demarcation bars in right-angled intersection and the calibrating tube that become sleeve-shaped of central axis upright in described two demarcation bar place planes, described calibrating tube is positioned at the position that two demarcation bars intersect, plug to be detected passes from described calibrating tube, and the two ends of described two demarcation bars are provided with for fixing pilot hole.
Preferably, described two demarcation bars intersect vertically.
Preferably, the position that described two demarcation bars intersect is provided with strengthening web.
Preferably, described strengthening web and described calibrating tube are welding as one.
Preferably, the axial length of described calibrating tube is 15-20cm.
The utility model has the advantage of: owing to embracing plug during backing roll original state, only unclamp plug in steel rolling by respective holder time side, the center therefore by detecting plug has that unchanged can to illustrate that the symcenter of backing roll has undeformed.Plug is when working dead ship condition, by plug is passed through from calibrating tube, due to reference axis during calibrating tube central axis on the utility model, if there is slight scratch in advance process, then illustrate that plug or the initial symcenter of backing roll there occurs deformation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail;
Fig. 1 is the structural representation of the verification pick-up unit of a kind of backing roll symcenter of the utility model and opening degree;
In figure: 1-demarcates bar, 2-calibrating tube, 3-pilot hole, 4-strengthening web.
Embodiment
Backing roll symcenter of the present utility model and the verification pick-up unit of opening degree comprise two demarcation bars 1 in right-angled intersection and the calibrating tube 2 that become sleeve-shaped of central axis upright in two demarcation bar 1 place planes, calibrating tube 2 is positioned at the position that two demarcation bars intersect, plug to be detected passes from calibrating tube 2, and the two ends of two demarcation bars 1 are provided with for fixing pilot hole 3.Owing to embracing plug during backing roll original state, only unclamp plug in steel rolling by respective holder time side, the center therefore by detecting plug has that unchanged can to illustrate that the symcenter of backing roll has undeformed.Plug is when working dead ship condition, by plug is passed through from calibrating tube 2, due to reference axis during calibrating tube central axis on the utility model, if there is slight scratch in advance process, then illustrate that plug or the initial symcenter of backing roll there occurs deformation.
By the setting that intersected vertically by two demarcation bars 1, thus the quick position being convenient to demarcate bar 1 is installed; And in order to strengthen the strength of joint of two demarcation bars 1, the position that two demarcation bars 1 intersect is provided with strengthening web 4; In order to strengthen the strength of joint of calibrating tube 2, strengthening web 4 and calibrating tube 2 are welding as one.In order to play calibrating tube central axis as the effect with reference to center, the axial length of calibrating tube 2 is 15-20cm, and such calibrating tube 2 will have certain contact length with plug, thus improves accuracy of detection.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and non-limiting technical scheme, those of ordinary skill in the art is to be understood that, those are modified to technical scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
