せるようになつている。 FIG. 1 shows the measuring device of this embodiment. This measuring device consists of a mounting table 1 on which a cylindrical object to be measured W is placed, and a circular plate that is loosely inserted into a cylindrical hollow part W of the object to be measured and is movable up and down in the axial direction. A columnar measuring head 2, a lifting mechanism (not shown) for raising and lowering the measuring head 2,
A first air supply mechanism 4 supplies compressed air to the measurement target W mounting surface 3 of the mounting table 1, and a second air supply mechanism 4 supplies compressed air outward from the outer peripheral surface of the measuring head 2 for the purpose of centering, which will be described later. It consists of an air supply mechanism 5, and an inner diameter measuring mechanism 6 for measuring the inner diameter. However,
The mounting table 1 includes a table-shaped main body part 7 in which a circular hole 1a having approximately the same diameter as the hollow part V is bored, and a circular hole 1a such that the object W to be measured is loosely fitted onto the main body part 7. It consists of an annular regulation wall part 8 coaxially bored.
In other words, a cylindrical hollow part 9 is formed by the regulating wall part 8, and the object W to be measured is placed in this hollow part 9 within a certain range determined by the gap between the object W to be measured and the regulating wall part 8. It is designed to be held movably on the mounting surface 3. And on the mounting surface 3,
As shown in FIG. 2, a plurality of air supply holes 10 (at least three) are equally spaced. These air supply holes 10 are connected to a first compressed air source (not shown),
It constitutes a first air supply mechanism 4. That is, the mounting surface 3 becomes a static pressure sliding surface by being supplied with compressed air from the air supply holes 10, and the object W to be measured can be moved with a slight force. On the other hand, the measuring head 2 has a cylindrical shaft part 11 connected to an elevating mechanism at one end and having an outer diameter smaller than the inner diameter of the hollow part 9, and the other end of this shaft part 11 is formed to be tapered. It consists of a tapered part 12. Air supply holes 13 (at least three) are opened in the outer circumferential surface of the tapered portion 12 in multiple stages in the axial direction, and are equally spaced along the circumferential direction. These air supply holes 13 are connected to a second compressed air source (not shown) and constitute the second air supply mechanism 5. Furthermore, the tapered portion 12 of the shaft portion 11
Air supply holes 14 (at least three) are opened in the outer circumferential surface of a portion adjacent to the air supply holes 14, which are equally spaced along the circumferential direction. These air supply holes 14... are each connected to a third compressed air source (not shown), and each of the air supply holes 14...
A plurality of pneumatic transducers (not shown) are installed to detect the back pressure of the compressed air ejected from the air. Further, each pneumatic exchanger is connected to an arithmetic device (not shown) that calculates the inner diameter of the hollow portion V based on the back pressure detection signals output from these pneumatic converters. These arithmetic device, pneumatic converter, third compressed air source, and intake hole 14 constitute the inner diameter measuring mechanism 6. On the other hand, the lifting mechanism

物Ｗの内径が算出される。 In the measuring apparatus having the above configuration, first, the measuring head 2 is raised in the direction of the arrow 15b. Then, compressed air is blown out from the air supply holes 10..., 13..., 14.... Then, the object W to be measured is placed on the placement surface 3. At this time, measurement head 2
Suppose that the axial center of the hollow part V is shifted from the axial center of the hollow part V. Therefore, when the measuring head 2 is lowered in the direction of the arrow 15a, the tip of the tapered part 12 comes into contact with the peripheral edge of the hollow part V, as shown by the imaginary line in FIG. Compressed air blown out from the air supply holes 13 at the lowest position applies a force to the object W in a direction coaxial with the measurement head 2. At this time, since the object W to be measured is supported in a non-contact manner by the static pressure of the compressed air from the air supply holes 10..., the object W to be measured is easily aligned by the compressed air from the air supply holes 13... You can move. However, since the gap between the measuring head 2 and the object to be measured W is large at this time, the alignment accuracy is poor. However, as the measuring head 2 is gradually inserted deeper into the hollow part V in the direction of the arrow 15a, the gap gradually narrows, and accordingly, the object W to be measured is gradually positioned coaxially with the measuring head 2. be done. Thus, at the stage when the measuring head 2 has descended to the position where the air supply holes 14 face the inner wall surface of the hollow portion V, the object W to be measured is completely aligned. Then, the inner diameter of the object W to be measured is calculated by the calculation device based on the detection signal output from the pneumatic converter indicating the back pressure of the compressed air blown out from the air supply holes 14 at this time.

物Ｗの内径測定精度も向上する。 In this way, the inner diameter measuring device of this embodiment can automatically align the object W to be measured with respect to the measurement head 2, so that damage to the object W due to a collision of the measurement head 2 can be avoided. This also improves measurement efficiency. Moreover, the accuracy of measuring the inner diameter of the object W to be measured is also improved.

The measuring head 21 in this case is cylindrical and has a hollow portion 23 into which a cylindrical object 22 to be measured is loosely inserted. On the inner wall surface of the tip of this measuring head 21,
A tapered portion 24 is formed having a larger diameter on the opening side. Air supply holes 25 (at least 3
) are open. In addition, air supply holes 26 for measuring the outer diameter (at least three) are bored in a portion close to the tapered portion 24 and are equally spaced along the circumferential direction.

Furthermore, the air supply holes for centering along the circumferential direction may be provided in one stage instead of in multiple stages. Furthermore, the measuring head side may be fixed and the mounting table side may be moved up and down.
