Description
本発明は、電極ロッドを有する電気溶接作業において、溶接作業中に溶接ビートの溶融状態を監視しながら溶接電流の調整を、溶接トーチを保持した手で、容易に、小さい動作角度で、溶接電流の調整を行う電気溶接機用トーチ。 According to the present invention, in an electric welding operation having an electrode rod, the welding current can be easily adjusted at a small operating angle with a hand holding the welding torch while monitoring the melting state of the welding beat during the welding operation. Electric welding machine torch that adjusts.
この種電気溶接機用トーチとして下記特許文献が存在する。
即ち図1の斜視図に示す如くトーチの筒状握手イの先端近傍の側部に電流調整器ロを装備し、その電流調整用の回転操作円板ハを指先にて回転させるようにしている。
而して、筒状握手イの先端と後端とを結ぶ線、所謂長手方向と平行(前後方向)に回転させるようにしている。
ところが、実際に回転操作円板ハを指先にて回転させるとなると、親指はトーチスイッチニを押えなければならないので、他の指先にて回転させなければならいが、この保持の方法では親指でトーチスイッチニを押したまま回転操作円板ハを指先にて回転させることは不可能で、溶接実施作業を中断することになる。勿論電流調整器ロを反対側即ち、手のひら側に位置させることも考えられるが、これでは指先で触れることが出来ず、結局は同じ様に、溶接実施作業を中断して回転操作円板ハを回転させることとなる。
溶接実施作業を中断することは、溶接ビートの継ぎ目を増加させる結果となるため、溶接ビートの継ぎ目の欠陥として、ピンホール等の溶接不良を招きやすい。
更に電流調整器ロ内部の回転式可変抵抗器に回転操作円板ハが直接取り付けてある為に操作角度は約1回転となる。その為回転操作円板ハを操作する指は長手方向に何度も往復する必要がある。
That is, as shown in the perspective view of FIG. 1, a current adjuster b is provided on the side near the tip of the cylindrical handshake i of the torch, and the current adjusting rotation operation disc C is rotated by the fingertip. .
Thus, the cylindrical handshake is rotated in a line connecting the front end and the rear end, that is, in parallel with the so-called longitudinal direction (front-rear direction).
However, when the rotating operation disc C is actually rotated with the fingertip, the thumb must press the torch switch, so it must be rotated with the other fingertip. It is impossible to rotate the rotating operation disc C with the fingertip while the switch is pressed, and the welding operation is interrupted. Of course, it is also possible to position the current regulator B on the opposite side, that is, on the palm side, but this cannot be touched with the fingertips. It will be rotated.
Since the interruption of the welding operation results in an increase in the seam of the welding beat, a welding defect such as a pinhole is likely to be caused as a defect in the seam of the welding beat.
Furthermore, since the rotary operation disc C is directly attached to the rotary variable resistor inside the current regulator B, the operation angle is about one rotation. Therefore, the finger for operating the rotary operation disc C needs to reciprocate many times in the longitudinal direction.
本発明は、電極ロッドを有する溶接トーチによる、電気溶接作業において溶接トーチを保持した手の指でトーチスイッチを押したまま、他の指で回転操作円板を回転させることによって、溶接トーチを保持した手の指で溶接実施作業を、中断することなく溶接電流調整を、少ない操作で行うことが出来る電気溶接機用トーチ。 The present invention uses a welding torch having an electrode rod to hold a welding torch by rotating a rotating operation disk with another finger while pressing a torch switch with a finger holding the welding torch in an electric welding operation. A torch for an electric welding machine that can perform welding current adjustment with a few fingers without interrupting the welding operation with the finger of the hand that has been done.
上記課題を解決するためになされた本発明の電機溶接用トーチは、電極ロッドを有するトーチヘッドと、前記トーチヘッドが先端に装備される筒状握手と、前記筒状握手の外周面を形成する筒面のうち下部側に設けられる電流調整器と、前記筒状握手の外周面を形成する筒面のうち下部側と反対側の上部側に設けられ、指で押圧可能なトーチスイッチと、前記筒状握手と前記トーチヘッドとの間に介在し、且つ筒状握手の先端と後端とを結ぶ線に対し直交する方向に回転可能な回転操作円板と、前記回転操作円板の外径より小径で当該回転操作円板の外周に位置し、且つ前記電流調整器に連結され、前記回転操作円板の回転が伝達される回転子と、前記筒状握手の後端から引き出される電流調整器のリード線およびトーチスイッチのリード線を備えた電気溶接用トーチであって、前記トーチスイッチの指で押圧する部分が前記回転操作円板の直上に配置されるようにして、親指でトーチスイッチを押圧しながらひとさし指で回転操作円板を回転する態様と、人差し指でトーチスイッチを押圧しながら、中指で回転操作円板を回転する態様との双方の持ち方で操作できるようにトーチスイッチと回転操作円板とを配置するようにしている（請求項１）。
上記発明において、回転操作円板の回転は当該回転操作円板の外周面に掛けられたベルトを介して前記回転子に伝達されるようにしてもよい（請求項２）。
上記発明において、ベルトは両側に脱落を防止するための挟みベルトガイドが装備されてもよい（請求項３）。An electric welding torch according to the present invention made to solve the above-mentioned problems forms a torch head having an electrode rod, a cylindrical handshake equipped with the torch head at the tip, and an outer peripheral surface of the cylindrical handshake. A current regulator provided on the lower side of the cylindrical surface; a torch switch provided on the upper side opposite to the lower side of the cylindrical surface forming the outer peripheral surface of the cylindrical handshake; A rotation operation disk interposed between the cylindrical handshake and the torch head and rotatable in a direction perpendicular to a line connecting the front end and the rear end of the cylindrical handshake; and an outer diameter of the rotation operation disk A rotor that has a smaller diameter and is positioned on the outer periphery of the rotary operation disk and is connected to the current adjuster, to which the rotation of the rotary operation disk is transmitted, and a current adjustment drawn from the rear end of the cylindrical handshake Lead wire and torch switch lead wire An electric welding torch provided, wherein a portion to be pressed with a finger of the torch switch is disposed immediately above the rotating operation disc, and the rotating operation disc is pressed with a forefinger while pressing the torch switch with a thumb. The torch switch and the rotation operation disc are arranged so that they can be operated in both the rotating manner and the manner in which the rotation finger is rotated with the middle finger while pressing the torch switch with the index finger. (Claim 1).
In the above invention, the rotation of the rotation operation disk may be transmitted to the rotor via a belt hung on the outer peripheral surface of the rotation operation disk.
In the above invention, the belt may be provided with a pinch belt guide for preventing the belt from falling off.
（１）請求項１により、トーチヘッドと筒状握手との間に筒状握手先端と後端とを結ぶ線に対し、直交する方向に回転する回転操作円板を装備することで、溶接トーチを保持した手の指でトーチスイッチを押したまま、他の指で回転操作円板を操作することが出来る。また、トーチスイッチの指で押圧する部分が回転操作円板の直上に配置されるようにしたので、トーチスイッチを押圧しながらひとさし指で回転操作円板を回転する態様と、人差し指でトーチスイッチを押圧しながら、中指で回転操作円板を回転する態様との双方の持ち方で操作できる。
また、回転操作円板に追随する回転操作円板より小さい回転子を、電流調整器の回転軸に連結させ回転操作円板より外周に配置することで電流調整器の回転軸を直接回転させる事になり、回転操作円板の回転角度は小さくなり溶接実施作業を中断することなく溶接電流を最弱から最強まで調整することが可能になる。
（２）請求項２により、回転操作円板の回転を、ベルトを介して回転子に伝達する事としたので、ギヤに異物がかみこみ操作不良を起こすこともなくなる。
（３）請求項３により、ベルトは両側に脱落を防止するための挟みベルトガイドが装備されるので、脱落が防止できる。 (1) According to claim 1, a welding torch is provided by providing a rotating operation disk that rotates in a direction orthogonal to a line connecting the front end and the rear end of the cylindrical handshake between the torch head and the cylindrical handshake. While holding the torch switch with the finger holding the hand, the rotation operation disk can be operated with another finger. In addition, since the part to be pressed with the finger of the torch switch is arranged immediately above the rotation operation disk, the rotation operation disk is rotated with the index finger while pressing the torch switch, and the torch switch is pressed with the index finger. On the other hand, it can be operated in both ways of holding the rotating operation disk with the middle finger.
In addition, a rotor smaller than the rotation operation disk that follows the rotation operation disk is connected to the rotation shaft of the current regulator and arranged on the outer periphery of the rotation operation disk, so that the rotation shaft of the current regulator is directly rotated. Thus, the rotation angle of the rotating operation disk becomes small, and the welding current can be adjusted from the weakest to the strongest without interrupting the welding operation.
(2) According to the second aspect, since the rotation of the rotating operation disk is transmitted to the rotor via the belt, foreign matter is not caught in the gear and the operation failure does not occur.
(3) According to the third aspect, since the belt is equipped with pinching belt guides for preventing the belt from falling off on both sides , the belt can be prevented from falling off.
