Description
本考案は、内径ネジの有効径の測定具に関する。 The present invention relates to a measuring tool for an effective diameter of an inner diameter screw.
従来の技術として、特許文献１に記載された「特殊鋼を用いて一部異なる形状の部品２個を作成し左用アタッチメント（１）と右用アタッチメント（２）とし、左用アタッチメント（１）と右用アタッチメント（２）にメートルネジのおねじの各要部をＪＴＳに基づく基本山形及び基本寸法の山形歯部を設けて、デジタルノギスの外側用ジョウ（１３）に左用アタッチメント（１）を外側用ジョウ（１４）に右側アタッチメント（２）をＭ４ボルト（１７）（１８）と（１９）（２０）で固定し加工する一般機械用めねじの有効径を測定するアタッチメント治具である技術 （下記の［特許文献］ 実用新案登録第３１７７１７３号公報の請求項１）」が開示されていた。
しかし、アタッチメント治具は、基本山形及び基本寸法の山形歯部（雄雌一対の替駒）を設けた左右アタッチメント（１）（２）と、デジタルノギスの外側用ジョウ（１３）（１４）を構成要件とするもので、アタッチメント治具の校正、精度保証は、アタッチメント治具全体についてしなければならないという従来技術の欠点が指摘されていた。
また、メートルネジ（６０°）、ユニファイネジ（６０°）、ウイットウオース（５５°）のサイズ毎に、それぞれ９種類、２６種類、２６種類のアタッチメント治具を揃える必要があり、各アタッチメント治具を多数揃えるのは、高価であり、被加工物の寸法が異なる場合を測定対象とする場合は、高コストになり現実的ではない。経済的に疑問であるという従来技術の欠点が指摘されていた（下記の表１を参照）。
また、計測者が当該アタッチメント治具を使用してネジ切りを行う場合、当該アタッチメント治具は市販されておらず、替駒の加工もメーカーでない計測者が行い、かつ、校正、精度保証も計測者が行わなければならず、現実には不可能であるという従来技術の欠点が指摘されていた。
As a conventional technique, as described in Patent Document 1, “parts of two different shapes using special steel are created to form a left attachment (1) and a right attachment (2), and a left attachment (1) and a right attachment. The main part of the male thread of the metric thread is provided on the attachment (2) with a basic chevron and a basic tooth part of the basic dimensions based on JTS, and the left attachment (1) for the outer jaw (13) of the digital caliper A technology that is an attachment jig that measures the effective diameter of a female screw for general machinery that fixes and processes the right attachment (2) to the jaw (14) with M4 bolts (17), (18), (19), and (20). [Patent Document] (Claim 1) of Utility Model Registration No. 3177173 was disclosed.
However, the attachment jig includes a left and right attachment (1) (2) provided with a basic chevron and a chevron tooth portion (a pair of male and female) of the basic dimensions, and an outer jaw (13) (14) of a digital caliper. It has been pointed out as a constituent requirement that the drawback of the prior art has been pointed out that calibration and accuracy assurance of the attachment jig must be performed for the entire attachment jig.
In addition, it is necessary to prepare 9 types, 26 types, and 26 types of attachment jigs for each size of metric screw (60 °), unified screw (60 °), and whitwash (55 °). It is expensive to arrange a large number of tools, and it is not practical because the cost is high when the object to be measured has different dimensions. The shortcomings of the prior art that have been questioned economically have been pointed out (see Table 1 below).
In addition, when the measurer performs threading using the attachment jig, the attachment jig is not commercially available, and the measurer who does not process the replacement piece performs the calibration and accuracy guarantee. However, it has been pointed out that the prior art has a drawback that it is impossible in reality.
考案者は、かかる従来技術の欠点に鑑み鋭意研究した結果、本願考案を完成させた。
本願考案に係る内径ネジの有効径の測定具について、ＦＩ、キーワード検索を行ったところ、本件考案（本願の［実用新案登録請求の範囲］の請求項１〜３に記載の考案）に近い考案等記載文献が、１件発見された。
The inventor completed the present invention as a result of diligent research in view of the drawbacks of the prior art.
As for the measuring tool for the effective diameter of the inner diameter screw according to the present invention, when FI and keyword search are performed, the present invention (the invention described in claims 1 to 3 of [Application for utility model registration] of the present application) is close to the present invention.

The digital caliper DN reading is set so that the nominal effective diameter Dne reading is zero.
For example, in the case of a screw of M180, p = 3, the nominal effective diameter Dne1 = φ178.051, but the reading of the digital caliper DN is set so that the reading of the display unit becomes zero.
● Step 7 (S7)
With the measuring tool 100 of the effective diameter of the inner diameter screw, the dimensional accuracy of the outer screw micrometer (commercially available product) is changed to the effective diameter De of the inner diameter screw (the reading of the display section is the difference ΔDe from the nominal effective diameter Dne of the inner diameter screw to be measured ).
● Step 8 (S8)
When the difference ΔDe is within the predetermined range, the determination is acceptable, and when the difference ΔDe is not within the predetermined range, the determination is unacceptable.
For example, in the case of a screw of M180, p = 3, if the difference ΔDe is within the range of +0.048 to +0.348, it will be accepted, and if it is not within the range of +0.048 to +0.348, it will be rejected. To do.

従来の技術として、特許文献１に記載された「特殊鋼を用いて一部異なる形状の部品２個を作成し左用アタッチメント（１）と右用アタッチメント（２）とし、左用アタッチメント（１）と右用アタッチメント（２）にメートルネジのおねじの各要部をＪＩＳに基づく基本山形及び基本寸法の山形歯部を設けて、デジタルノギスの外側用ジョウ（１３）に左用アタッチメント（１）を外側用ジョウ（１４）に右側アタッチメント（２）をＭ４ボルト（１７）（１８）と（１９）（２０）で固定し加工する一般機械用めねじの有効径を測定するアタッチメント治具である技術 （下記の［特許文献］ 実用新案登録第３１７７１７３号公報の請求項１）」が開示されていた。
しかし、アタッチメント治具は、基本山形及び基本寸法の山形歯部（雄雌一対の替駒）を設けた左右アタッチメント（１）（２）と、デジタルノギスの外側用ジョウ（１３）（１４）を構成要件とするもので、アタッチメント治具の校正、精度保証は、アタッチメント治具全体についてしなければならないという従来技術の欠点が指摘されていた。
また、メートルネジ（６０°）、ユニファイネジ（６０°）、ウイットウオース（５５°）のサイズ毎に、それぞれ９種類、２６種類、２６種類のアタッチメント治具を揃える必要があり、各アタッチメント治具を多数揃えるのは、高価であり、被加工物の寸法が異なる場合を測定対象とする場合は、高コストになり現実的ではない。経済的に疑問であるという従来技術の欠点が指摘されていた（下記の表１を参照）。
また、計測者が当該アタッチメント治具を使用してネジ切りを行う場合、当該アタッチメント治具は市販されておらず、替駒の加工もメーカーでない計測者が行い、かつ、校正、精度保証も計測者が行わなければならず、現実には不可能であるという従来技術の欠点が指摘されていた。

(The following [Patent Document] Utility Model Registration No. 3177173, Claim 1) was disclosed.
However, the attachment jig includes a left and right attachment (1) (2) provided with a basic chevron and a chevron tooth portion (a pair of male and female) of the basic dimensions, and an outer jaw (13) (14) of a digital caliper. It has been pointed out as a constituent requirement that the drawback of the prior art has been pointed out that calibration and accuracy assurance of the attachment jig must be performed for the entire attachment jig.
In addition, it is necessary to prepare 9 types, 26 types, and 26 types of attachment jigs for each size of metric screw (60 °), unified screw (60 °), and whitwash (55 °). It is expensive to arrange a large number of tools, and it is not practical because the cost is high when the object to be measured has different dimensions. The shortcomings of the prior art that have been questioned economically have been pointed out (see Table 1 below).
In addition, when the measurer performs threading using the attachment jig, the attachment jig is not commercially available, and the measurer who does not process the replacement piece performs the calibration and accuracy guarantee. However, it has been pointed out that the prior art has a drawback that it is impossible in reality.
