Abstract

<P>PROBLEM TO BE SOLVED: To shorten work time for attaching/detaching a nut. <P>SOLUTION: A pair of half nuts 4 integrally constituted of a half female screw 4 of an outer surface tapered body and a guide key 5 are positioned in a holder 2 and assembled on a base 1 (having a guide function) with a straight key groove passing through the center of the product. On the other hand, an inner surface of a set upper 3 is brought into contact with an outer surface tapered portion of the half nuts 4 positioned on the opposite of the attached base. The motion of the half nuts is converted into the orthogonal direction (a direction for clamping the bolt) by insertion of the set upper 3, and the female screws are moved toward inner/outer periphery direction to control "to engage" and "not to engage" with male screws of the bolt (non-constraint body) 9. This function provides easy attachment/detachment for the nut. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
通常ナットをボルトに組み付けるにはナットを拘束する面に当たるまで回転させてねじこみ、スパナを用いて完全固定する。
これでは取付け・取り外し作業に時間がかかりすぎるため、これを改善するため考案した。
【0002】
【従来の技術】
今日まで同じ目的のものがあったが小さな難切削品のコマ、薄板状のカバー等を用いたワンタッチ操作の精密加工品であった。よって、より強度の高いものが必要であった。
【0003】
【特許文献1】
特許NO.1058063
【0004】
【解決しようとする課題】
とりわけ強力なトルクおよび耐久性が求められる分野においても適用可能な早締め、早外しナットが求められている。
【0005】
本発明はワンタッチとはいかないまでも耐久性のある早締め、早外しナットとして社会に貢献できることを目的とする。
【0006】
【課題を解決しようとする手段】
【0007】
【構造と機能】
外面テーパ体の2分割雌ねじ4とガイドキー5を一体構造にしたハーフナット4一対がホルダー2内に置かれ、製品中心を通過する直線キー溝を有した(ガイド機能を持った)ベース1上に組みつけられている。一方、取付けられたベースとは反対の位置にあるハーフナット4外面テーパ部にセットアッパー3の内面が接している。このセットアッパー3のねじ込みでハーフナット4の動きは直角方向(ボルトをクランプする方向)に変換され、雌ねじ山が内・外径の方向へ移動する。そしてボルト(被拘束体)9の雄ねじ山との「噛み合わせる」「噛み合わせない」をコントロールする。この機能で、本ナットは容易に取付け・取り外しができることになる。
【0008】
セットアッパー3はゆるめられており、このハーフナット4は取付け時点ではホルダー2内において外方向へ圧縮ばね7で押し広げられ、雌ねじ内径面は被拘束体10であるボルト外径より外にセットされている。この時ハーフナット4外面はホルダー2内径面に当たっている。(同時にガイドキー5外側先端は本体より突き出ている。)
このセットでは本ナットは障害なく目的の取付け位置付近への挿入は可能である。
【0009】
前記したセット品を取付けボルト9の固定部付近まで挿入した時点で、本ナットの両外面にあるハーフナット4のキー5の突き出し部を親指と一指し指で挟み、被拘束体ボルトねじ山とハーフナット4ねじ山の噛み合わせを確認しながら本ナットの位置を決め、セットアッパー3をねじ込むとテーパ内面でハーフナット4のテーパ外面が内側へ押され、被拘束体ねじ山と噛み合うように目的の位置へセットされる。
そして、スパナを用い数回差し替えながら、ナットを完全に締め込み固定する。
【0010】
スパナを用いナットが自由に回るところまで(約半回転)緩め、ゆるんだところで片手でホルダー2外部を掴み、もう一方の片手でセットアッパー3を数回転ゆるめる。
ハーフナット4の雌ねじがボルト9雄ねじとの噛み合いから外れたところで、そのまま抜き取る。
【0011】
【発明の実施の形態】
量産品である板金製品のゆがみをおさえ密着させるべく本ナットを使って強く締める。工作機械で加工品の固定あるいは製品固定用クランプをセットするスタッドボルトに使用する。このような時、本製品の能力が発揮される。
【0012】
【実施例】
板金製品を溶接する治具の製品拘束ブロックを締め上げる。ボール盤での加工品のクランプを固定する。コンベアラインで製品固定する。
【0013】
【発明の効果】
従来品に比べ、同類品とは交換時間はあまり変わらないがケース部、ナット部、セットアッパーが機械加工品であることにより堅牢な製品となった。
突き出たキー5先端を指で押してのねじ山位置合わせは簡単である。

TECHNICAL FIELD OF THE INVENTION
Normally, to assemble the nut to the bolt, rotate the screw until it hits the surface that restrains the nut, screw it in, and fix it completely using a spanner.
This requires too much time for installation and removal, so we devised it to improve this.
[0002]
[Prior art]
To date, there has been a product with the same purpose, but it was a precision-processed product with one-touch operation using a small difficult-to-cut top and a thin cover. Therefore, a material having higher strength was required.
[0003]
[Patent Document 1]
Patent No. 1058063
[0004]
[Problem to be solved]
In particular, there is a need for a quick-tightening and quick-release nut that can be applied even in fields where strong torque and durability are required.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to contribute to society as a durable fast-fastening and fast-unfastening nut, if not one-touch.
[0006]
[Means to solve the problem]
[0007]
[Structure and function]
A pair of half nuts 4 each having a two-piece female screw 4 and a guide key 5 of an external taper body are placed in a holder 2 and on a base 1 (having a guide function) having a linear keyway passing through the center of the product. Has been assembled. On the other hand, the inner surface of the set upper 3 is in contact with an outer tapered portion of the half nut 4 located at a position opposite to the attached base. When the set upper 3 is screwed in, the movement of the half nut 4 is converted into a right angle direction (a direction in which the bolt is clamped), and the female screw thread moves in the inner and outer diameter directions. Then, “meshing” and “not meshing” with the external thread of the bolt (constrained body) 9 are controlled. With this function, the nut can be easily attached and detached.
[0008]
The set upper 3 is loosened, and the half nut 4 is pushed outward by the compression spring 7 in the holder 2 at the time of mounting, and the inner diameter of the female screw is set outside the outer diameter of the bolt which is the constrained body 10. ing. At this time, the outer surface of the half nut 4 is in contact with the inner surface of the holder 2. (At the same time, the outer end of the guide key 5 protrudes from the main body.)
In this set, the nut can be inserted near the target mounting position without any obstacle.
[0009]
When the above-mentioned set product is inserted to the vicinity of the fixing portion of the mounting bolt 9, the projecting portions of the key 5 of the half nut 4 on both outer surfaces of the nut are pinched with the thumb and one-point finger, and the captive member bolt thread and Determine the position of this nut while confirming the engagement of the threads of the half nut 4 and screw in the set upper 3 so that the tapered inner surface of the half nut 4 is pushed inward by the tapered inner surface, so that it engages with the restricted body thread. Is set to the position.
Then, while replacing the nut several times using a spanner, completely tighten and fix the nut.
[0010]
Using a spanner, loosen the nut until it can rotate freely (about a half turn), grasp the outside of the holder 2 with one hand when the nut is loosened, and loosen the set upper 3 several times with the other hand.
When the female screw of the half nut 4 comes out of engagement with the male screw of the bolt 9, it is pulled out as it is.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Tighten tightly with this nut to hold down the distortion of mass-produced sheet metal products and keep them tight. Used for stud bolts for fixing clamps for fixing processed products or products in machine tools. In such a case, the performance of the product is exhibited.
[0012]
【Example】
Tighten the product restraint block of the jig for welding sheet metal products. Fix the clamp of the workpiece on the drill press. Fix the product on the conveyor line.
[0013]
【The invention's effect】
Compared to conventional products, the replacement time is not much different from similar products, but the case part, nut part, set upper are machined products, so they are robust products.
Thread positioning by pushing the tip of the protruding key 5 with a finger is easy.
