Description

本発明は損傷した雄ねじ山を修正する為の工具に関する。The present invention relates to a tool for correcting a damaged male thread.

従来のねじ山修正器はねじ切りダイスを２分割してねじを内側部分から修正可能としたものがある（例えば特許文献１参照）
また、２本爪形状の切削刃でねじの谷部分を削る事が可能な様に配置している物もある（例えば非特許文献１参照）Some conventional screw thread correctors divide the threading die into two parts so that the screw can be corrected from the inner side (see, for example, Patent Document 1).
In addition, there is an object arranged so that the trough portion of the screw can be cut with a two-claw-shaped cutting blade (for example, see Non-Patent Document 1).

従来のねじ山修正器はねじのピッチとねじの太さ正逆ねじに応じた個別の専用ねじ切りダイスを用いた物で大量の専用の２分割ダイスが必要であり又２本爪形状の切削刃でねじの谷部分を削る物は損傷具合の大きい物は正確に元通りのピッチのねじ山に修正出来ないという問題が有った。  The conventional thread corrector uses individual dedicated thread cutting dies according to the screw pitch and thread thickness forward / reverse thread, requires a large number of dedicated two-part dies, and has a two-jaw-shaped cutting blade. However, there was a problem that the thing which cuts the root part of the screw could not be corrected to the thread with the original pitch accurately.

本発明は、従来のねじ山修正器が有していた問題を解決した物であり、大量の専用の２分割ダイスを必要とせず、一つのねじ山修正器で多種類のねじのピッチとねじの太さ正逆ねじに対応出来て元通りの正確なねじ山に修正を可能とする事を目的とするものである。  The present invention solves the problems of conventional thread correctors, and does not require a large number of dedicated two-part dies. The purpose is to be able to cope with the normal and reverse thread of the thread and to correct the original thread correctly.

本発明は上記目的を達成する為にねじ修正刃をねじのピッチと同形状の一枚刃とする事で正逆どちらのねじにも対応可能とし、破損していない部分のねじ山がガイドになることで元通りの正確なねじ山に修正する事を可能とした。  In order to achieve the above object, the present invention makes it possible to deal with both forward and reverse screws by using a single blade with the same shape as the screw pitch, and the thread of the undamaged portion is used as a guide. By doing so, it was possible to correct it to the exact thread as it was.

一枚刃のねじ修正刃の数箇所に違うピッチのねじ修正刃を配する事で一枚のねじ修正刃で数種類の異なるピッチのねじの修正を可能とした。  By arranging screw correction blades with different pitches at several locations on a single blade screw correction blade, it is possible to correct several types of screws with different pitches with a single screw correction blade.

調整ノブを回し移動支持具片を移動させる事でねじ修正刃とガイドローラーの間隔を調整可能とする事で様々な太さのねじや配管のねじのねじ山修正を可能とした。  By turning the adjustment knob and moving the moving support piece, it is possible to adjust the distance between the screw correction blade and the guide roller, thereby making it possible to correct the threads of various thickness screws and pipe threads.

本発明のねじ山修正器は一つのねじ山修正器で多種類のねじのピッチとねじの太さ、正逆ねじのどちらにも対応出来て元通りの正確なねじ山に修正をする事が可能なので従来のねじ山修正器の様に大量の専用２分割ダイスを必要とせず一つのねじ山修正器とねじのピッチに応じた数枚のねじ修正刃で数百種類のねじや配管のねじの修正が可能になった。  The thread corrector of the present invention can be applied to any of a variety of screw pitches, screw thicknesses, and forward / reverse threads with a single thread corrector. Because it is possible, hundreds of types of screws and pipe screws are possible with one screw corrector and several screw correction blades according to the screw pitch without the need for a large number of dedicated two-part dies like conventional screw correctors Can now be corrected.

本発明のねじ山修正器は修正するねじのピッチと同形状の枚刃を使用しているので、ねじの修正状態を目視しながらねじの破損状態に応じてねじ修正刃とガイドローラーの間隔を調整しながら少しずつ修正する事が出来る。  Since the thread corrector of the present invention uses a single blade having the same shape as the pitch of the screw to be corrected, the distance between the screw correcting blade and the guide roller is set according to the broken state of the screw while visually checking the corrected state of the screw. It can be corrected little by little while adjusting.

本発明のねじ山修正器は先端部分が破損したねじも２分割ダイスを使用せずにねじの途中部分から先端かけて修正する事が出来る。  The screw thread corrector according to the present invention can correct a screw having a broken tip portion from the middle portion of the screw to the tip without using a two-part die.

以下、本発明の実施の形態を図１〜図４に基づいて説明する。  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

図１、図２においては１本体に５圧力調整ねじを介して平行移動可能に配した２移動支持片に７ねじ修正刃を９ねじ修正刃取り付けワッシャーと８修正刃取り付けねじで固定して１本体に取り付けられた３ガイドローラーＡと４ガイドローラーＢと７ねじ修正刃の間に１０修正される破損したねじを６圧力調整ねじに固定された５圧力調整ノブよって圧力を調整しながら図３の様に挟み１０修正される破損したねじを中心に１本体を回転させる事で破損したねじ山部分を元通りの正確なねじ山に修正出来る事を可能とした。  In FIGS. 1 and 2, a 7-screw correcting blade is fixed to a main body by a 9-screw correcting blade mounting washer and an 8 correcting blade mounting screw on a 2-moving support piece arranged to be movable in parallel through a 5 pressure adjusting screw. 3 while adjusting the pressure with a 5 pressure adjusting knob fixed to a 6 pressure adjusting screw for a broken screw 10 corrected between 3 guide roller A, 4 guide roller B and 7 screw correcting blades attached to the main body. By rotating one body around the damaged screw to be pinched 10 as shown in the above, it is possible to correct the damaged screw thread portion to the original exact screw thread.

図４においては１本体に７ねじ修正刃を９ねじ修正刃取り付けワッシャーと８修正刃取り付けねじで固定して１本体に５圧力調整ねじを介して平行移動可能に配した２移動支持片に３ガイドローラーＡと４ガイドローラーＢを配し１０修正される破損したねじを６圧力調整ねじに固定された５圧力調整ノブよって圧力を調整しながら挟み１０修正される破損したねじを中心に１本体を回転させる事で破損したねじ山部分を元通りの正確なねじ山に修正出来る事を可能とした実施例である。  In FIG. 4, a 7-screw correcting blade is fixed to one main body with a nine-screw correcting blade mounting washer and an eight-correcting blade mounting screw, and three moving support pieces are arranged on one main body so as to be movable in parallel via five pressure adjusting screws. A main body centered on the broken screw which is fixed by pinching 10 while adjusting the pressure by the 5 pressure adjusting knob fixed to the 6 pressure adjusting screw. This is an embodiment in which it is possible to correct a thread portion that has been damaged by rotating the screw to the exact thread as it was.
