PURPOSE:To extremely quickly and easily measure a coaxial degree by holding at least two points in the outside diameter part of a ferrule to prevent the outside diameter part from oscillation, rotating the ferrule and measuring the displacement at the edge of the capillary thereof. CONSTITUTION:The ferrule 1 is held by a V-block 3 and is rotated by a motor 5 via a driving belt 6 in such a manner that the outside diameter part does not oscillate. The scale line 10 of the edge is matched with the edge of the capillary by a microscope 7 in a position where the edge of the capillary comes to the leftmost position. The scale line 10' of the edge is similarly matched therewith in a position 2' when the left side of the edge comes to the rightmost position. The spacing (a) between the line 10 and the line 10' is then read. The spacing (a) is the coaxial degree of the capillary with respect to the outside diameter of the ferrule and can be directly read by the microscope 7. |
