Adopt technique scheme, in use, be clamped on axle to be detected by the first roller set and the second roller set, then plectane is promoted, ball is conflicted on the center pit of axle to be detected, ball is utilized to coordinate with the center pit of axle to be detected, ensure that annulus can be treated detection axis in fixing position and detect, when this measurer can be rotated smoothly, just ensure that four rolling is all tangent with axle to be detected, because the first roller set and the second roller have employed above-mentioned structure, the now center line certainty of slide bar and certain diameter conllinear on axle to be detected section, when this measurer of rotation, the center line of slide bar remains and the diameter conllinear of on this section, and synchronously displacement can be there is when the diameter of axle to be detected changes in slide bar, easy to operate and error is less, utilize laser range sensor can record the change of the displacement of the handle when rotating this measurer, to the data analysis of record just can the cylindrical of detected position to axle to be detected beat, avoid personal error.By tightening and unclamp the position that set nut regulates annulus on guide rod, to treat the detection that detection axis carries out multiple location.Air discharge duct is set at slide bar, for exhaust and discharge impurity, prevents slide bar to be stuck, ensure that the movement that slide bar can be smooth, reduce error further.Be provided with spring, slide bar can be stretched, so this measurer can be applicable to the axial workpiece of multiple diameter, and spring makes four rolling remain tangent with axle to be detected, ensure that accuracy of detection.
Further, described roller is bearing.Bearing low cost, rolling characteristics is good.
Further, the edge of described plectane is provided with the bar hole running through described plectane.Arranging bar hole is that the hand of conveniently operating personnel stretches in bar hole and holds plectane, rotates to control this measurer.
The utility model structure is simple, and easy to operate, can detect that the cylindrical of axial workpiece is beated fast, error is little, utilizes laser range sensor can obtain the maximum of cylindrical and least count accurately, avoids the error that human factor causes.
