For reaching above-mentioned purpose, it is flange opening, offset measuring device that the utility model provides a kind of axle of the present utility model, comprises 1 C type support, 1 cylinder, 2 dial gauges and some bolts, nut.
On described C type support, have multiple through holes and screw, there is through hole in described cylindrical center; By described screw bolt and nut, described cylinder is connected on described C type support; By bolt, described dial gauge is arranged on described C type support.
Size and flange thickness according to tested flange bolt hole center to outer rim, determine the length on 3 limits of described C type support, and after described C type support is installed, the minimum spacing on whole circumference and between tested flange is greater than 10mm.
According to the diameter of bolt hole on tested flange and flange thickness, determine diameter and the length of described cylinder, the diameter of described cylinder should be than the diameter of bolt hole on tested flange little 2mm, length should be than the little 10mm of tested flange thickness.
In certain embodiments, have 6 holes on C type support, its mesopore 1, hole 3, hole 4 are through hole, and hole 2, hole 5, hole 6 are screw, and there is 1 through hole at the center of described cylinder.The diameter in hole, hole 1, hole 3 and hole 4 is 8～10mm, and hole 2, hole 5 and hole 6 screw threads are M6 or M8.
In certain embodiments, 2 dial gauges are respectively used to measure opening value and the off-set value of flange, and described dial gauge is arranged in hole 3 and hole 4, and bolt is screwed into hole 5 and hole 6.
Brief description of the drawings
