Abstract

PURPOSE:To position the light through hole of a target in the center of a body to be centered speedily with high precision by using a holder which holds the target, a main body which supports it movably, and plural supports which expand and contact freely. CONSTITUTION:The target 8 is supported by the target holder 9, which is supported by the main body 10. The main body 10 is provided with three supports 24 which contact the internal surface of the body 23 to be centered at about 120 equal angles. A sub-support 30 is rotated properly almost to the center position of the body 23 to be centered to adjust the length, arranging the centering device. Then, the distance from a surface 32 to be machined to the outer circumferential surface of the target holder 9 is measured by an inside micrometer 33 and a micrometer 14 fixed to the main body 10 is rotated on the basis of the measured value to move the target holder 9, positioning the light through hole 8a at an axial center position.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is directed to optical centering of an object having a hole of an arbitrary shape quickly and with high precision.
I am concerned with the number 1.

I. Technical Background of the Invention] In general, a centering device that performs centering using light, for example, is used to center various single-piece devices.

Figure 1 shows the state in which the turbine cooling sink is being centered using this centering device. JtJ, so J3 is shown in the diagram (Jungetsu 1 is a turbine engine consisting of a ten-half conductor, one-half conductor, and one-half conductor 1b).

(Objective of the Invention) The present defense is explained below.) Since the invention was made to deal with the conventional situation, for example, the light passing hole of the tag 1- can be quickly and accurately placed in the center of the object to be centered, such as J of the turbine casing. C monkey of positioning in the mausoleum. [Summary of the Invention 1] In other words, the present defense is based on a target holder having a light passage hole and holding a target holder 1, A centering device is used to move the holder, such as a water body supported by a single ladle. do.

[Embodiments of the Invention] An example of Kazumi #Ili will be explained based on the drawings of Metoki Ytaki.

Figure 2 shows an example of Ming's wooden block.
In the figure, reference numeral C 8 indicates a cross-shaped target with a light passage hole Qa drilled in the center. This target 8 is supported by a target holder 9), and the target 1 to holder 9 are movably supported by the water body 10 (1°J to the target holder 9) as shown in FIG. ni, targtu 1-
ε3 is a support 1, a circle 1; As shown in FIG. 4, the tips of a microphone 11 and a meter 14, which are respectively supported by the main body 10 and supported by the support body 13, are in contact with the two sides of the ring.

A lino missing part 1b is formed at the corner where the microphone 11 and the meter 14 of Targtsu 1 to Small Lug 5) come into contact with l<Lj〃 ((

Furthermore, in Fig. 2, J3 is attached to the main body 10 (, shi, haba 120
A three-piece glue port 24 is provided which abuts the inner surface of the -C centering object 2:3 having an angle of .degree.
