Description
本考案は長さ測定器としてのデジタルノギスに関するものである。 The present invention relates to a digital caliper as a length measuring device.
従来この種のデジタルノギスとして、一方の測定ジョーを有する本尺と、該本尺に移動自在に設けられ、他方の測定ジョーを有するスライダと、該スライダの移動変位量を検出する変位検出手段と、該スライダに設けられ、該移動変位量をデジタル表示するデジタル表示部とを備えてなる構造のものが知られている。 Conventionally, as this type of digital caliper, a main scale having one measuring jaw, a slider provided movably on the main scale and having the other measuring jaw, and a displacement detecting means for detecting the amount of displacement of the slider A structure having a digital display provided on the slider and digitally displaying the amount of movement displacement is known.
しかしながら上記従来構造において、例えば、エレベータ用ワイヤロープの線径を測定する場合、ワイヤロープは一般的に８ｍｍ程度の比較的に細い線径のもの、あるいは、１２ｍｍ〜１８ｍｍ程度の太い線径のもの等、多種の線径のものがあり、又、ワイヤロープは、複数の素線を撚った複数のストランドを芯網に撚り合わせて形成され、ストランドはＺ撚り、Ｓ撚り等に撚られて線方向に傾斜し、山と谷が交互に形成されているから、山と山との距離を線径としなければならないにも拘わらず、山と谷との距離を線径として測定することもあり、線径を誤って測定してしまうことがあるという不都合を有している。 However, in the above conventional structure, for example, when measuring the wire diameter of an elevator wire rope, the wire rope is generally a relatively thin wire diameter of about 8 mm, or a thick wire diameter of about 12 mm to 18 mm. The wire rope is formed by twisting a plurality of strands obtained by twisting a plurality of strands to a core network, and the strands are twisted by Z twist, S twist, etc. Inclines in the line direction, and peaks and valleys are alternately formed, so the distance between the peaks and valleys can be measured as the wire diameter, even though the distance between the peaks and peaks must be the wire diameter. There is a disadvantage that the wire diameter may be erroneously measured.
本考案はこれらの不都合を解決することを目的とするもので、本考案のうちで、請求項１記載の考案は、一方の測定ジョーを有する本尺と、該本尺に移動自在に設けられ、他方の測定ジョーを有するスライダと、該スライダの移動変位量を検出する変位検出手段と、該スライダに設けられ、該移動変位量をデジタル表示するデジタル表示部とを備えてなり、上記一方の測定ジョー及び上記他方の測定ジョーにそれぞれ円盤状の測定子を設けてなることを特徴とするデジタルノギスにある。 The present invention aims to solve these inconveniences. Among the present inventions, the invention described in claim 1 is provided with a main scale having one measuring jaw and a movable main scale. A slider having the other measuring jaw, a displacement detection means for detecting the displacement of the slider, and a digital display provided on the slider for digitally displaying the displacement of the slider. The digital caliper is characterized in that each of the measuring jaw and the other measuring jaw is provided with a disk-shaped measuring element.
又、請求項２記載の考案は、上記測定子は上記測定ジョーにボルトにより止着固定されていることを特徴とするものである。 The invention described in claim 2 is characterized in that the measuring element is fixed to the measuring jaw by a bolt.
本考案は上述の如く、請求項１記載の考案にあっては、本尺に対してスライダを移動させ、一方の測定ジョーに設けられた測定子の測定面と他方の測定ジョーに設けられた測定子の測定面とを被測定物としてのワイヤロープに対向当接し、このときのスライダの移動変位量が変位検出手段により検出され、この変位検出手段により検出された移動変位量は線径の測定値としてデジタル表示部に表示されることになり、この際、上記一方の測定ジョー及び上記他方の測定ジョーにそれぞれ測定子を設けているから、一方の測定ジョー及び他方の測定ジョーが被測定物としてのワイヤロープに当接するのではなく、一方の測定ジョーに設けられた円盤状の測定子及び他方の測定ジョーに設けられた円盤状の測定子が被測定物に対向当接することになり、細い線径のもの、あるいは、太い線径のもの等、多種の線径のもの、複数の素線を撚った複数のストランドを芯網に撚り合わせて形成されたワイヤロープであっても、被測定物の線径を迅速にかつ正確に測定することができ、かつ、上記測定子は円盤状に形成されているから、被測定物の線径方向と測定子との測定の方向性がなくなり、線径測定を容易に行うことができる。 As described above, according to the present invention, the slider is moved with respect to the main scale, and the measuring surface of the measuring element provided on one measuring jaw and the other measuring jaw are provided. The measuring surface of the measuring element is brought into contact with a wire rope as an object to be measured, and the moving displacement amount of the slider at this time is detected by the displacement detecting means, and the moving displacement amount detected by the displacement detecting means is equal to the wire diameter. The measured value will be displayed on the digital display. At this time, since the one measuring jaw and the other measuring jaw are provided with measuring elements, one measuring jaw and the other measuring jaw are measured. Rather than abutting a wire rope as an object, a disk-shaped measuring element provided on one measuring jaw and a disk-shaped measuring element provided on the other measuring jaw are opposed to the object to be measured. A wire rope formed by twisting a plurality of strands obtained by twisting a plurality of strands into a core net, and having a variety of wire diameters such as a thin wire diameter or a thick wire diameter In addition, since the wire diameter of the object to be measured can be measured quickly and accurately, and the measuring element is formed in a disk shape, the direction of the measurement of the wire diameter direction of the object to be measured and the measuring element The wire diameter can be easily measured.
又、請求項２記載の考案にあっては、上記測定子は上記測定ジョーにボルトにより止着固定されているから、測定ジョーに測定子を容易に取り付けることができ、取付構造を簡素化することができ、測定子の取り替えも容易に行うことができ、使用の利便性を向上することができる。 According to the second aspect of the present invention, since the measuring element is fastened and fixed to the measuring jaw with a bolt, the measuring element can be easily attached to the measuring jaw, and the mounting structure is simplified. Therefore, the probe can be easily replaced, and the convenience of use can be improved.

In this case, as shown in FIGS. 3 and 4, one measuring jaw 1a and the other measuring jaw 1a. The width of the measurement surface 2a, ie, the thickness as the width of the measurement surface is 3 mm, whereas the diameter of the measurement surfaces 5a and 5a of the measuring element 5 and 5 is 20 mm, respectively. The bolts 6 and 6 are immersed so as not to protrude from the measurement surfaces 5a and 5a of the measuring elements 5 and 5.
この場合、上記本尺１に本尺目盛１ｂが形成され、上記スライダ２に本尺目盛１ｂを読み取る基線としての基線端縁部２ｂが形成されている。 In this case, a main scale 1b is formed on the main scale 1, and a base line edge 2b is formed on the slider 2 as a base line for reading the main scale 1b.

The measuring surface 5a of the measuring element 5 provided on 2a is brought into abutment with a wire rope as the object W to be measured, and the displacement of the slider 2 at this time is detected by the displacement detecting means 3, and this displacement detecting means 3 The displacement amount detected by the above is displayed on the digital display unit 4 as a measured value of the wire diameter D.
この際、図１、図２、図３の如く、上記一方の測定ジョー１ａ及び上記他方の測定ジョー２ａにそれぞれ円盤状の測定子５・５を設けているから、一方の測定ジョー１ａ及び他方の測定ジョー２ａが被測定物ＷとしてのワイヤロープＷに当接するのではなく、一方の測定ジョー１ａに設けられた測定子５及び他方の測定ジョー２ａに設けられた測定子５が被測定物ＷとしてのワイヤロープＷに対向当接することになり、細い線径のもの、あるいは、太い線径のもの等、多種の線径のもの、複数の素線を撚った複数のストランドを芯網に撚り合わせて形成されたワイヤロープであっても、被測定物Ｗの線径Ｄを迅速にかつ正確に測定することができ、かつ、上記測定子５・５は円盤状に形成されているから、被測定物Ｗとしてのワイヤロープの線径方向と測定子５・５との測定の方向性がなくなり、線径測定を容易に行うことができる。 At this time, as shown in FIGS. 1, 2 and 3, the one measuring jaw 1a and the other measuring jaw 2a are provided with disc-shaped measuring elements 5 and 5, respectively. The measuring jaw 2a is not in contact with the wire rope W as the object to be measured W, but the measuring element 5 provided on one measuring jaw 1a and the measuring element 5 provided on the other measuring jaw 2a are not measured. The wire rope W as W is opposed to the wire rope W, and the core wire is formed of a plurality of strands in which a plurality of strands are twisted with various wire diameters such as a thin wire diameter or a thick wire diameter.
