Described first roller set and described second roller set include base and are disposed in parallel in two rollers on base, the centerline axis parallel of described roller is in the central axis of described first annulus, two rollers in described first roller set with described reference field for the plane of symmetry is symmetrical arranged, two rollers in described second roller set with described reference field for the plane of symmetry is symmetrical arranged, roller in described first roller set and described second roller set is all towards the center line of described second annulus, employing such a construction ensures reference field and is bound to and treats that a diameter of ruling axle end face is coplanar.
Adopt technique scheme, being clamped in by the first roller set and the second roller set treats on ruling axle, then the first annulus is promoted, station meter is conflicted on the end face treating ruling axle, when this device can be rotated smoothly, just ensure that four rolling all with treat that ruling axle is tangent, because the first roller set and the second roller set have employed above-mentioned structure, now on the inevitable end face with treating ruling axle of reference field, certain diameter is coplanar, scriber is utilized to carry out ruling on this end face along reference field and just can obtain required diameter, the diameter that the position adjusting this device marks more than two just can determine the center of circle of this end face, operate very simple, fast.Be provided with spring, slide bar can be stretched, so this device can be applicable to the axial workpiece of multiple diameter, and spring makes four rolling remain and treats that ruling axle is tangent, ensure that line precision.
Further, described roller is bearing.Bearing low cost, rolling characteristics is good.
Further, the sidewall subscript of described slide bar is marked with scale.Adopt said structure, the cylindrical of the detection axial workpiece that this device can be utilized rough is beated, and utilizes the scale on slide bar to carry out reading during detection.
In sum, the utility model can draw diameter and the center of circle at the end face of axial workpiece fast and accurately.
