Abstract

(57) [Summary] [Purpose] Anyone can accurately measure the outer diameter of the wire rope. [Structure] Measuring surface of main scale 1 and slider 2 having vernier
In the caliper for measuring the outer diameter of the object to be measured with the measuring surface of (1), a pair of contact plates 3 having a wide measuring surface are provided so as to face the jaw of the main scale 1 and the jaw of the slider 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a caliper contact plate for measuring wire rope.

[0002]

[Prior art]

 When measuring the outer diameter of the wire rope (Fig. 1), conventionally, a commercially available caliper (Fig. 2) is used. The outer diameter of the wire rope was measured between the main scale 1 and the slider 2 having a vernier, but it was difficult to measure accurately because the outer circumference of the wire rope was uneven (see FIG. 3).

[0003]

[Problems to be solved by the device]

 SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art, and an object thereof is to enable anyone to accurately measure the outer diameter of the wire rope.

[0004]

[Means for Solving the Problems]

 In a caliper that measures the outer diameter of the object to be measured between the measuring surface of the main scale and the measuring surface of a slider with a vernier, a pair of contact plates with a wide measuring surface are used to connect the jaw of the main scale and the slider It was provided opposite to. Further, a pair of contact plates are detachably attached to the main scale jaw and the slider jaw. In particular, the pair of contact plates can be attached / detached by fixing them to the main scale jaw and the slider jaw with a set screw.

[0005]

[Action]

 Insert the wire rope between the measuring surface of the contact plate on the jaw of the main scale and the measuring surface of the contact plate on the jaw of the slider, and measure the outer diameter of the wire rope (see Fig. 6). ).

[0006]

Embodiments of the present invention will be described with reference to the drawings. FIG. 4 is a plan view of a main part of the wire rope measuring caliper of the present invention, FIG. 5 is a sectional view taken along the line AA of FIG. 4, and FIG. It is a figure.

In FIG. 4, 1 is a main scale, 2 is a slider having a vernier, and a pair of contact plates 3 are provided so as to face the jaw of the main scale 1 and the jaw of the slider 2.

The contact plate 3 is detachably attached to the jaw of the main scale 1 and the jaw of the slider 2 by a set screw 4.

As described above, since the wire rope measuring caliper of this embodiment has a configuration in which the contact plate 3 and the stop screw 4 are simply added, a commercially available caliper can be used for the caliper body.

[0010]

[Effect of device]

 By providing a pair of contact plates with a wide measuring surface and selecting only the wire rope with high unevenness, the outer diameter of the rope can be accurately measured by anyone. In addition, it is cheap because it only requires a contact plate and a set screw on the caliper body.
