Specific embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawing.
The concentricity testing device of the reducing-sizing mill collars of the utility model is as shown in FIG. 1 to 3, mainly includes branch
Frame ontology 1, the axis of rolling 2 to support collars, lever indicator 3, several axis of rolling 2 are set on rack body 1 in parallel and energy
It is enough freely rotated, and wherein one end of an axis of rolling 2 is equipped with rotary drive mechanism, 1 side upper end of rack body is equipped with dial gauge
Fixed station 4, lever indicator 3 are fixedly arranged on dial gauge fixed station 4.
As one embodiment, the rack body 1 is mutual including bottom plate 11 and vertical a pair on bottom plate 11
Parallel support plate 12, such as using with a thickness of 20mm stainless steel plate, dial gauge fixed station 4 is located therein the upper of a support plate 12
End, rotary drive mechanism are set to the outside of another support plate 12, and the bottom surface of bottom plate 11 is also provided with four adjusting stabilizer blades, to
Regulating guarantee stability.
The axis of rolling 2 is left, center, right three, and rotary drive mechanism is connected with the intermediate axis of rolling 2, three rollings
The outer diameter of axis 2 is φ 80mm, length 125mm, and both ends are fixed between two support plates 12 by installing bearing, the axis of rolling 2
Arrangement be parallel to each other.
Spacing such as 95mm between the axis of rolling 2 of the centre and the axis of rolling 2 on the left side and it is less than the intermediate axis of rolling 2
Spacing such as 215mm between the axis of rolling 2 on the right, in this way, can be placed in intermediate and the left side 2 middle upper part of the axis of rolling outer
Diameter is the collars to be measured of 142-150mm, and can place outer diameter in intermediate and the right 2 middle upper part of the axis of rolling is 206-250mm
