動させる。An embodiment of the present invention will be described below with reference to FIGS. 3 to 6. That is, 11 in the figure is a main body, and this main body 11 has a cylindrical shape, and an alignment shaft hole 13 is formed in the center. Further, a pair of support arms 21.21 are protruded from the outer peripheral surface of the main body 11, and casters 22.22 are attached to the tips of these support arms 21.21, respectively.
is installed. The main body 11 is inserted into the orifice hole 2 of the member to be measured, for example, the orifice 1, and the caster 22.2 at the tip of the support arm 21.21 is inserted into the orifice hole 2 of the member to be measured.
2 is in contact with the upper surface of the orifice 1 and supports the main body 11 so as to be movable along a plane perpendicular to the axial direction of the orifice hole 2. Furthermore, three alignment pin holes 15 are formed at equal intervals along the radial direction at the lower end of the main body 11. A centering body, such as a centering bottle 16, is fitted into each of these centering bottle holes 15 so as to be slidable in the radial direction. These alignment bins 16...
Both ends of the centering pins 16 are formed into spherical shapes, and the ends of the centering pins 16 protrude from the outer circumferential surface of the main body 11 and the inner surface of the centering shaft hole 13, respectively. Further, an alignment mechanism such as an alignment shaft 12 is screwed into the alignment shaft hole 13, and by rotating this alignment shaft 12, the alignment shaft 1
2 is configured to move up and down. A tapered portion 14 is formed at the lower end of the alignment shaft 12. Therefore, as the alignment shaft 12 moves up and down, the tapered portion 14 at the lower end comes into contact with the end of the alignment pin 16 and pushes them in the radial direction, causing the alignment pins 16 and ... are synchronized and moved in the radial direction so that their tips are always located on the circumference centered on the center of the main body 11.

1 into the orifice hole 2 of the orifice 1 to be measured. Then, the alignment shaft 12 is rotated and lowered. Therefore, the tapered portion 14 of the alignment shaft 12 synchronously pushes out the alignment pins 16 in the radial direction. Therefore, the tips of these alignment pins 16 come into contact with the inner surface of the orifice hole 2, and the main body 11 is moved so as to be located at the center of the orifice hole 2. Next, the loopers 20.20 are moved, and these loopers 20.20 are positioned at the edge of the chamfered part 3, and these loopers 20.20 are moved to the edge of the chamfered part 3 and the scale 18a of the scale 18.18. , 18a is enlarged, and the scale 18a, 1 where the edge of this chamfered portion 3 matches is shown.
Read sa. Then, this read scale 18a, 1
Double the value in 8a to find the dimension d2 of the chamfered portion 3.
