이때, 내측에 스프링(54a)이 내장 설치되어 있어 가변지지보올(54)은 보올내장홈(50) 내부에서 전,후방으로 움직이되, 탄성지지력이 가해지는 상태에서 스핀들연장부(4a)가 움직이면서 조정하게 되면 고정지지보올(24)과 대향측의 가변지지보올(54)이 시일면(110)에 접하게 되면서 경사각(110)이 비대칭으로 서로 중심이 다르더라도 상기 보올(24,54)에 의하여 측정하고자 하는 위치에서 다이얼게이지(4)의 인디케이터 눈금값에 의하여 측정할 수 있게 된다.At this time, the spring 54a is installed inside the variable support bowl 54 is moved forward and backward inside the bowl built-in groove 50, the spindle extension (4a) in the state that the elastic support force is applied When the adjustment is made while moving, the fixed support ball 24 and the variable support ball 54 on the opposite side come into contact with the seal surface 110, but the inclination angles 110 are asymmetrically different from each other by the balls 24 and 54, respectively. It is possible to measure by the indicator scale value of the dial gauge (4) at the position to be measured.

따라서, 본 발명에 의하면 연료교환기 시일이나 기타 관련 물품의 제작시 가공이 이루어지는 경우 오차가 적게 내경 또는 외경의 치수 측정이 손쉽게 이루어질 수 있어 가공시간의 단축과 방사선 피폭의 저감이 이루어지고, 정비품질의 향상은 물론 시일의 잘못된 제작을 사전에 방지할 수 있으며, 정비시간의 단축을 이룩할 수 있고, 하나의 몸체(1)를 활용하여 일측 고정지지부(3)와 대향측 가변지지부(6)의 설치를 내,외경 설치부(3a,3b)(6a,6b)의 설치위치에 따라 선택적으로 방향에 맞추어 각각 설치하여 시일면의 내경 또는 외경을 측정하는데 공용으로 활용할 수 있는 등의 우수한 효과를 갖게 된다.Therefore, according to the present invention, when the processing of the fuel exchanger seal or other related articles is made, the measurement of the inner diameter or the outer diameter can be easily performed with little errors, thereby reducing the processing time and reducing the radiation exposure, thereby improving maintenance quality. Improved, of course, it can prevent the wrong production of the seal in advance, can achieve a shortening of the maintenance time, by using one body (1) to prevent the installation of one side fixed support (3) and the opposite side variable support (6) According to the installation position of the inner and outer diameter mounting portions 3a, 3b and 6a and 6b, respectively, it can be selectively installed according to the direction, and thus it can be used in common for measuring the inner or outer diameter of the seal surface.
