State the axle center fixation branch that two roll surfaces of roll surface turning cutting tool both sides grip briquetting and are arranged in grinding roller axis through-hole
Support；The axle center fixing support rack includes an axle center and fixes support column and several radially fixed support columns, the axle center
The axis of fixed support column and the axis collinear of grinding roller, several described radially fixed support column being radially arranged along grinding roller, and
One end of each radially fixed support column is fixedly connected with the axle center and fixes support column, each radially fixed support column
The other end be provided with axle center support rotating wheel, the roll surface of axle center support rotating wheel is close to the inner side of grinding roller axis through-hole
Wall；The axis of each axle center support rotating wheel with grinding roller diameter parallel.
As the further improvement of above-mentioned technical proposal, the radially fixed support column is four and coplanar setting, and four
The individual radially fixed support column is symmetrical around the axis centre of grinding roller, and radially fixed support column water described in two of which
Flat to set, two other described radially fixed support column is vertically arranged；Two roll surfaces grip briquetting relative to overground
The vertical plane of roll axis is symmetrical arranged, and the roll surface turning cutting tool sets and is located at milling roller surface apex straight down.
As the further improvement of above-mentioned technical proposal, each roll surface, which grips briquetting, includes drive installation
Post, the briquetting installation fixed block for being arranged at the drive installation post end, the arc being arranged on the briquetting installation fixed block
Elastic metallic tabletting, the arc elastic metal sheeting is arranged at towards the abrasion-proof rubber cushion on milling roller surface one side；It is described
Radian under arc elastic metal sheeting nature is less than the roll surface radian of grinding roller；Each roll surface grips briquetting
The drive installation post is horizontally disposed.
As the further improvement of above-mentioned technical proposal, the axis of two built-up welding rotary supporting rollers is horizontal and parallel
In grinding roller, two built-up welding rotary supporting rollers are symmetrical arranged relative to the vertical plane of overground roll axis.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of large-scale roller surface provided by the present invention repairs anti-deformation truning fixture, by setting two roll surfaces to grip
Briquetting, it can stably fix large-scale grinding roller；And by setting axle center fixing support rack, it can avoid because two roll surfaces clamp
The unequal caused grinding roller skew of power that fixed briquetting applies, and can avoid because two roll surfaces grip briquetting application
Grinding roller caused by force direction has minor deviations is offset；And axle center fixing support rack is set to ensure that the shaft core position of grinding roller is consolidated
It is fixed, so as to ensure the accuracy of turning operation, make the large-scale milling roller surface after turning operation that there is preferable circularity.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation that a kind of large-scale roller surface of the present invention repairs anti-deformation truning fixture.
