The outer diameter of the second reference surface 4 is set to be larger than the outer diameter of the lip 1a of the seaming chuck. Further, the second reference plane 4 is orthogonal to the axis of the spindle mounting hole 32. Therefore, the operation direction of the micrometer spindle 15 is orthogonal to the second reference plane 4.

Thus, the second reference plane 4 is provided perpendicular to the direction of movement of the micrometer spindle 15, while the first reference plane 3 is also perpendicular to the direction of movement of the micrometer spindle 15. Since it is provided,

This is because the direction of movement is orthogonal to the direction of movement. In order to know the absolute value of the SCH, it is preferable to measure in advance the distance between two points where the inside distance is known, and check the absolute value corresponding to each scale. As described above, since the outer diameter of the second reference surface 4 is set to be larger than the outer diameter of the lip 1a of the seaming chuck, only one measurement is required.

The overall length of the intermediate portion 26 of the jig body is preferably as short as possible from the viewpoint of improving the stability of the seat during measurement, but is large enough to allow the micrometer head 10 to be inserted through the window 23. Limited due to the need to secure. When the spindle 15 is driven downward, the speeder 13 extends downward. However, in order to alleviate this limitation, a hole 25 having a diameter larger than the diameter of the speeder 13 is formed in the center of the bottom plate 24a. It is preferable to provide them.

In the present embodiment, the jig body intermediate portion 26 has a cylindrical shape having an opening as shown in FIG.

FIG. 5 shows an SCH measuring apparatus and a measuring jig provided with measuring jigs at both ends of the inner micrometer 40. Here is the inner micrometer,
A micrometer provided with a spindle as a measuring end at both ends and having a total length that expands and contracts and measures a distance between two points formed by two objects. Attachments 31a and 31b formed of two flat plates are provided at the ends of the spindles 15a and 15b at both ends of the inner micrometer 40 so as to be fixed to be perpendicular to the direction of spindle movement. The inner micrometer 40 itself is extended, and the SCH is measured such that the attachments 31a and 31b fixed to both ends thereof are in contact with the lifter plate 2 and the lowermost point of the chuck lip 1a. The attachment 31a,
It is desirable that the flat plate diameter of 31b is provided larger than the outer diameter of chuck lip 1a. In one measurement, S
This is because CH can be obtained.

FIG. 6 shows a state in which an attachment 31 is provided on one spindle 15a of the inner micrometer 40, and this is brought into contact with the chuck lip 1a side to measure SCH. Since the upper surface of the lifter plate 2 is a flat surface, attachments 31a and 31b are provided on both sides shown in FIG. 5 by providing a jig 31 having a flat plate having an outer diameter larger than the outer diameter of the chuck rib 1a only on the chuck spindle 15a. The same operation and effect as those of the measuring device can be obtained.

This is a measuring device that can obtain the function and effect. In this case, since the weight of the device itself becomes large,
It is desirable to replace the material with a lightweight material such as plastic as long as rigidity and wear resistance are allowed.

In the above embodiment, the materials of the attachment 31 and the jig body 21 are as follows.
The material is not limited as long as it has sufficient strength to maintain the accuracy of the measurement, but generally plastic or steel is used. When using plastic, select a material and shape (especially thickness) with sufficient rigidity, a material with a low coefficient of linear expansion with respect to temperature, and a material with high wear resistance to maintain measurement accuracy. is necessary. The wear resistance is mainly determined by the first reference surface 3 and the second reference surface 3.
Since it is required for the reference surface 4, an extremely thin steel plate can be attached only to this portion, and the other portions can be made of plastic.

The method of fixing the attachment 31 to the tip of the spindle 15 of the micrometer head is, for example, a method of welding when the material of the attachment 31 is steel, or a method of fixing with an adhesive.
In addition, it is desirable to provide a mounting hole 32 at the center of the attachment 31 so that the tip of the spindle 15 is fitted, and fix the mounting hole 32 at this portion from the viewpoint of increasing strength and durability. When the material of the attachment 31 is plastic, it is recommended that the attachment 31 be fixed by using an adhesive.

The method of fixing the stem 14 of the micrometer head to the fitting hole 27 provided in the top plate 24b of the jig body 21 may be a screwing method shown in FIG. However, from the viewpoint of selecting a method in which an excessive force is not applied to the inside of the micrometer head 10, a male screw is cut into the micrometer stem portion 14, and a female screw is cut into the inner surface of the fitting hole 27, and the two are screwed into each other. 3 and FIG. 4 are recommended.

Although the attachment 31 and the bottom plate 24a of the jig main body 21 are shown as disc-shaped flat plates, the present invention is not limited to this. Either the attachment 31 or the bottom plate 24a of the jig main body 21 may have a structure capable of supporting the entire measuring device on the lifter plate 2.
It may be a tripod with point support or a pentapod with five points.
