A kind of novel milling train centre bore calibrating installation
Technical field
The utility model relates to a kind of novel milling train centre bore calibrating installation, belongs to plant equipment field of auxiliary.
Background technology
The center line calibration steps that current routine uses uses bracing wire calibration, and due to Action of Gravity Field, the sag of remote bracing wire is also larger, affect calibration accuracy, and whether line also must with the naked eye judge by rule of thumb in center, make the precision of detection low, labour intensity is large.
Utility model content
The purpose of this utility model is: for the upper defect of prior art, provides a kind of novel milling train centre bore calibrating installation, and this structure is simple, and calibration accuracy height labour intensity is little, to overcome the deficiencies in the prior art.
The technical solution of the utility model
A novel milling train centre bore calibrating installation, comprises rolling mill body, arranges laser positioning parts, arrange concentric scale at the afterbody of rolling mill body at the rod mouth of rolling mill body, and these laser positioning parts and concentric scale to be positioned in same level and to be in alignment with each other.
In aforesaid a kind of novel milling train centre bore calibrating installation, described laser positioning parts adopt laser flashlight, between the rod mouth and laser positioning parts of rolling mill body, nylon material sleeve pipe is set, this nylon material sleeve pipe is cone structure, and the nylon material sleeve pipe of conical structure can adapt to different milling train rod oral pore passes.
Owing to have employed technique scheme, compared with prior art, the utility model is by being fixed on the rod mouth of milling train by laser projection device, make ray cast on the scale that can be fixed on milling train, then the position of adjustment milling train is moved according to the luminous point be projected on scale, adjust to the center of scale until light spot position till, laser positioning parts and concentric scale are set up, make it can ensure that the centre bore of each section of milling train is located along the same line when calibrating more than ten centre bores of milling train, solve owing to wasting time and energy when bracing wire is calibrated and the not high problem of precision, and this structure is simple, easy to make, practical.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
Embodiment of the present utility model: a kind of novel milling train centre bore calibrating installation, as shown in drawings, comprise rolling mill body 1, at the rod mouth of rolling mill body 1, laser positioning parts 2 are set, at the afterbody of rolling mill body 1, concentric scale 3 is set, these laser positioning parts 2 and concentric scale 3 to be positioned in same level and to be in alignment with each other, wherein these laser positioning parts 2 adopt laser flashlight, between the rod mouth and laser positioning parts 2 of rolling mill body 1, nylon material sleeve pipe 4 is set, this nylon material sleeve pipe 4 is that conical structure is to adapt to the milling train centre bore aperture of different size, concentric scale 3 adopts transparent hard plastic material, and whole circular scale 3 is printed on some concentric circles and central point by determining diameter and forms coordinate system.
By laser projection device being fixed on the rod mouth of milling train in the present embodiment, make ray cast on the scale that can be fixed on milling train, then the position of adjustment milling train is moved according to the luminous point be projected on scale, adjust to the center of scale until light spot position till, make it can ensure that the centre bore of each section of milling train is located along the same line when calibrating more than ten centre bores of milling train, solve owing to wasting time and energy when bracing wire is calibrated and the not high problem of precision.
