Description

자동 위빙용 티그용접 홀더Tig welding holder for automatic weaving
본 발명은 자동 위빙용 티그용접 홀더에 관한 것으로, 보다 상세하게는 전동모터에 평심 결합된 회전판에 돌기부를 형성하고, 티그토치의 내부에 형성된 하우징에 삽입된 텅스텐 전극봉과 돌기부를 위빙와이어로 연결하여 전동모터의 작동으로 일정하게 텅스텐 전극봉을 위빙 시키는 자동 위빙용 티그용접 홀더에 관한 것이다.The present invention relates to a tig welding holder for automatic weaving, and more particularly, by forming a protrusion on a rotating plate flatly coupled to an electric motor, and connecting the tungsten electrode and the protrusion inserted in the housing formed inside the tig torch with a weaving wire. It relates to a Tig welding holder for automatic weaving that constantly weaves a tungsten electrode by the operation of an electric motor.
일반적으로 티그용접은 아르곤이나 헬륨 등의 불활성가스를 보호가스로 사용하면서 비소모성 전극인 텅스텐 전극과 용접 부재 사이에서 발생시킨 아크열로 모재를 용융시켜 접합하는 용접법이다.In general, TIG welding is a welding method in which an inert gas such as argon or helium is used as a protective gas and the base material is melted and joined by arc heat generated between a tungsten electrode, which is a non-consumable electrode, and a welding member.
이러한 용접법은 용가재를 공급하여 부재와 함께 용융시키기도 한다. 그리고 보호가스로는 부재와 텅스텐 전극의 산화를 방지하기 위하여 불활성가스인 아르곤이나 헬륨 등을 사용하므로 TIG(Tungsten Inert Gas) 용접으로 부르고 있다.In this welding method, the filler material is supplied and melted together with the member. And as the protective gas, argon or helium, which is an inert gas, is used to prevent oxidation of the member and the tungsten electrode, so it is called TIG (Tungsten Inert Gas) welding.
또한, 티그용접법은 모든 용접자세에 적용할 수 있으며, 아크가 매우 안정되고 용접부 품질이 우수하므로 산화나 질화 등에 민감한 재질의 용접 및 피복아크용접이 적용하기 곤란한 경우에 사용된다.In addition, the TIG welding method can be applied to all welding postures, and since the arc is very stable and the quality of the welding part is excellent, it is used when it is difficult to apply the welding of materials sensitive to oxidation or nitriding and the coated arc welding.
이러한 종래의 티그용접법은 티그토치 내부의 텅스텐 전극봉과 모재에 용접 전원을 접속하고 텅스텐 전극봉과 모재 사이에 용접 아크를 형성하여 용접용 첨가와이어를 수동으로 아크부에 송급하여 아크열로 녹여 용접이 된다.In this conventional Tig welding method, a welding power source is connected to the tungsten electrode and the base material inside the Tig torch, and a welding arc is formed between the tungsten electrode and the base material, and the additional wire for welding is manually supplied to the arc part and melted by arc heat for welding. .
이와 같이 티그용접은 티그토치의 운봉과 용접와이어 송급 방법에 따라 수동, 반자동, 자동 티그용접으로 나뉜다.As described above, Tig welding is divided into manual, semi-automatic, and automatic Tig welding according to the method of feeding the Tig Torch and the welding wire.
여기서, 티그토치의 운봉과 용접와이어의 송급을 수동으로 할 경우를 수동 티그용접이라고 한다. 그리고 티그토치의 운봉만 수동으로 할 경우 반자동 티그용접, 티그토치의 운봉과 용접와이어의 송급을 자동으로 할 경우를 자동 티그용접이라 한다.Here, the case of manually feeding the tig torch and the welding wire is called manual tig welding. In addition, when only the moving rod of the Tig torch is performed manually, the case of semi-automatic Tig welding, and the case of automatically feeding the Tig Torch's moving rod and welding wire is called automatic tip welding.
일반적으로 파이프의 용접은 수동 티그용접과 자동 티그용접이 적용되고 있다.In general, manual and automatic tig welding are applied to pipe welding.
또한, 자동 티그용접은 용접될 파이프의 주위에 설치된 레일을 따라 캐리지가 회전하면서 용접을 수행하나 회전 자동 티그 용접장치는 외산의 매우 고가 제품이고 위보기 용접자세에서 이면 용접비드의 루트 오목비드가 형성된다.In addition, automatic Tig welding performs welding while the carriage rotates along the rail installed around the pipe to be welded, but the automatic TIG welding device is a very expensive product of foreign production, and the root bead of the welding bead is formed on the back side in the above welding position. do.
따라서, 파이프의 개선 형상을 V자홈이 아닌 U자홈으로 준비하여야 하므로 개선 가공시간이 늘어나고 용접선을 따라 레일 설치를 정밀하게 해야한다. 그리고 실제 용접외 용접준비시간이 많이 필요하므로 용접사의 접근이 어려운 용접부위 외에는 그 적용이 매우 제한적이다. 이러한 이유로 인해 파이프 용접의 대부분은 수동 티그 용접이 적용되고 있다.Therefore, since the improved shape of the pipe must be prepared as a U-shaped groove instead of a V-shaped groove, the improvement processing time is increased and the rail installation along the welding line must be precisely performed. And since a lot of welding preparation time is required in addition to the actual welding, its application is very limited except for the welding part where the welder's access is difficult. For this reason, most of the pipe welding is a manual tig welding is applied.
또한, 수동 티그용접은 용접작업자가 한손으로는 티그 토치 헤드를 좌우로 계속 위빙하면서 다른 한손으로 첨가 와이어를 계속적으로 아크 내에 삽입하여야 하므로 용접작업자의 높은 집중력과 섬세함과 고기량이 요구된다.In addition, manual Tig welding requires a welding operator to continuously weave the Tig Torch head left and right with one hand and insert the additional wire into the arc with the other hand, so the welding operator's high concentration, delicacy, and high volume are required.
특히, 수동 티그용접은 용접 전류를 공급하는 전력선, 텅스텐 전극봉과 모재의 산화를 방지하기 위한 보호가스 및 텅스텐 전극봉에서 발생하는 열을 감소시키기 위한 냉각수 등이 공급되도록 구성되어 있다.In particular, manual TIG welding is configured to supply a power line supplying welding current, a protective gas to prevent oxidation of the tungsten electrode and the base material, and coolant to reduce heat generated from the tungsten electrode.
이때, 티그 용접토치에 공급되는 전력선, 보호가스와 냉각수의 급수관과 배수관 및 이들을 보호하기 위한 외피 등으로 구성된 토치케이블을 들고 티그토치를 손목을 이용하여 좌우로 위빙하여 용접함에 따라 용접작업자의 피로도가 높고 손목, 어깨 허리 등 근골격계 질환의 원인이 되고 있으며, 용접작업자가 장시간 연속 작업을 할 수 없으므로 용접생산성이 매우 낮은 단점이 있다.At this time, the welding worker's fatigue is increased by weaving and welding the Tig torch left and right using the wrist while holding the torch cable composed of the power line supplied to the Tig welding torch, the water supply pipe and drain pipe of the protective gas and cooling water, and the outer shell to protect them. It is high and causes musculoskeletal diseases such as wrist, shoulder and waist, and welding productivity is very low because the welding worker cannot work continuously for a long time.

도 1에 도시된 바와 같이, 본 발명의 실시예에 따른 자동 위빙용 티그용접 홀더(10)는 하우징(100), 위빙부(200) 및 작동부(300)를 포함한다.As shown in FIG. 1, the automatic weaving Tig welding holder 10 according to an embodiment of the present invention includes a housing 100, a weaving unit 200, and an operation unit 300.
보다 상세하게는, 도 1 및 도 4에 도시된 바와 같이, 본 발명의 실시예에 따른 자동 위빙용 티그용접 홀더(10)는 텅스텐 전극봉(11)이 구비된 티그토치(12)와 티그토치의 일측에 연결된 손잡이(13)가 형성되어 텅스텐 전극봉을 위빙시키는 자동 위빙용 티그용접 홀더에 있어서, 티그토치의 내부에 소정거리 이격되어 텅스텐 전극봉이 삽입된 하우징(100), 텅스텐 전극봉을 위빙시키는 위빙부(200) 및 위빙부의 작동을 제어하는 작동부(300)를 포함한다.In more detail, as shown in FIGS. 1 and 4, the automatic weaving tig welding holder 10 according to the embodiment of the present invention includes a tung torch 12 provided with a tungsten electrode 11 and a tig torch. In the automatic weaving tig welding holder that has a handle 13 connected to one side to weave the tungsten electrode, the housing 100 in which the tungsten electrode is inserted and spaced a predetermined distance from the inside of the tig torch, and the weaving part for weaving the tungsten electrode It includes 200 and an operation unit 300 for controlling the operation of the weaving unit.
도 1 및 도 2를 참조하면, 하우징(100)은 텅스텐 전극봉(11)이 유격을 가지며 삽입될 수 있게 티그토치(12)내부에 이중관 형상으로 형성된다.Referring to FIGS. 1 and 2, the housing 100 is formed in a double tube shape inside the tig torch 12 so that the tungsten electrode 11 can be inserted with a gap.
이러한 하우징(100)은 바디관(110), 콜렛바디부(120) 및 유격부(130)를 포함한다.The housing 100 includes a body tube 110, a collet body 120 and a clearance 130.
바디관(110)은 길이방향으로 연장되고 하부의 지름이 좁은 관 형상으로 형성된다.The body tube 110 extends in the longitudinal direction and is formed in a tube shape having a narrow lower diameter.
즉, 바디관(110)의 하부의 지름을 좁게 형성하여 후술하는 위빙부(200)로 콜렛바디부(120)를 위빙 시키는 경우, 콜렛바디부(120)에 삽입된 텅스텐 전극봉(11)의 선단을 바디관(110)의 수직한 축을 중심으로 예약을 형성되게 하여 용접봉과 모재에 보호가스를 공급할 수 있게 한다.That is, when the collet body part 120 is weaved with the weaving part 200 to be described later by forming a narrow diameter of the lower part of the body tube 110, the tip of the tungsten electrode 11 inserted into the collet body part 120 A reservation is formed around the vertical axis of the body tube 110 so that the protective gas can be supplied to the welding rod and the base material.
또한, 바디관(110)은 위빙와이어(240)가 콜렛바디부(120)에 연결되도록 관통된 홀이 형성되는 것이 바람직하다.In addition, it is preferable that the body tube 110 has a hole through which the weaving wire 240 is connected to the collet body 120.
콜렛바디부(120)는 바디관(110)의 내부에 위치하고, 텅스텐 전극봉(11)이 삽입된다.The collet body part 120 is located inside the body tube 110 and the tungsten electrode 11 is inserted therein.
이를 위해, 콜렛바디부(120)는 바디관(110)의 내측으로부터 이격되는 관 형상으로 형성되고, 텅스텐 전극봉(11)의 지름에 대응하여 형성된다.To this end, the collet body 120 is formed in a tube shape spaced apart from the inner side of the body tube 110 and is formed corresponding to the diameter of the tungsten electrode 11.
또한, 콜렛바디부(120)는 불활성가스가 바디관(110)의 내부로 유입 시 텅스텐 전극봉이 불활성가스에 노출되는 것을 방지하는 역할을 한다.In addition, the collet body 120 serves to prevent the tungsten electrode from being exposed to the inert gas when the inert gas flows into the body tube 110.
이러한 콜렛바디부(120)는 외주면 일측에 고리가 형성되어 위빙와이어(240)가 연결되게 한다.The collet body part 120 has a ring formed on one side of the outer circumferential surface so that the weaving wire 240 is connected.
한편, 여기 명세서의 도면에서 콜렛바디부(120)는 수직하게 도시되어 있으나, 탄성부(260)의 방향으로 수직한 중심선이 기울어져 있는 것이 바람직하다.On the other hand, in the drawings of the present specification, the collet body part 120 is shown vertically, but it is preferable that the center line perpendicular to the direction of the elastic part 260 is inclined.
이는, 위빙와이어(240)가 콜렛바디부(120)를 잡아당긴 후, 느슨해질 때 탄성부(260)가 콜렛바디부(120)를 잡아당김으로써, 수직한 축을 기준으로 콜렛바디부(120)를 좌우 방향으로 위빙시키기 위해서이다.This is, after the weaving wire 240 pulls the collet body portion 120, the elastic portion 260 pulls the collet body portion 120 when it becomes loose, so that the collet body portion 120 with respect to a vertical axis This is to weave in the left and right directions.
유격부(130)는 콜렛바디부(120)의 상부가 적어도 하나 이상 분리되는 분리부(131)가 형성되고 분리부(131)를 둘러싸는 탄성띠(133)가 형성되어 텅스텐 전극봉(11)의 상부 외주면에 접촉하되 유격을 형성한다.The clearance 130 is formed with a separating portion 131 in which at least one upper portion of the collet body 120 is separated, and an elastic band 133 surrounding the separating portion 131 is formed so that the tungsten electrode 11 It contacts the upper outer circumferential surface, but forms a gap.
이때, 유격부(130)는 탄성띠가 분리부(131)로부터 이탈되는 것을 방지하기 위해 콜렛바디부(110)의 상부에 상하방향으로 서로 이격된 한 쌍의 플랜지로 형성된 단턱(132)을 형성하는 것이 바람직하다.At this time, the clearance part 130 forms a stepped 132 formed of a pair of flanges spaced apart from each other in the vertical direction on the upper part of the collet body part 110 to prevent the elastic band from being separated from the separation part 131 It is desirable to do it.
이러한 유격부(130)는 콜렛바디부(120)의 내부로 삽입된 텅스텐 전극봉(11)을 잡아주는 홀더역할을 한다.The clearance 130 serves as a holder for holding the tungsten electrode 11 inserted into the collet body 120.
도 1 및 도 3을 참조하면, 위빙부(200)는 텅스텐 전극봉(11)을 위빙 시킨다.1 and 3, the weaving part 200 weaves the tungsten electrode 11.
이를 위해, 위빙부(200)는 전동모터(210), 회전판(220), 회전돌기부(230), 위빙와이어(240) 및 위빙판(250)을 더 포함한다.To this end, the weaving unit 200 further includes an electric motor 210, a rotating plate 220, a rotating protrusion 230, a weaving wire 240 and a weaving plate 250.
전동모터(210)는 손잡이(13)의 내부에 위치하는 것으로, 바디관(110)에 인접하여 후술하는 회전판(220)을 회전시키는 역할을 한다.The electric motor 210 is located inside the handle 13 and serves to rotate the rotating plate 220 to be described later adjacent to the body tube 110.
회전판(220)은 원형의 판으로 형성되고, 판의 중심으로부터 편심된 위치에 전동모터(210)에 결합되어 편심 회전을 하게 된다.The rotating plate 220 is formed as a circular plate, and is coupled to the electric motor 210 at an eccentric position from the center of the plate to perform eccentric rotation.
즉, 회전판(220)은 편심을 축으로 회전하여 후술하는 위빙와이어(240)가 콜렛바디부(120)를 좌우방향의 회전범위를 크게 형성시켜 준다.That is, the rotating plate 220 rotates around an eccentric axis so that the weaving wire 240, which will be described later, makes the collet body part 120 a larger rotational range in the left and right directions.
회전돌기부(230)는 회전판(220)의 지름상에 돌출되고, 내부에 볼베어링이 구비되어 회전한다.The rotation protrusion 230 protrudes on the diameter of the rotation plate 220, and a ball bearing is provided therein to rotate.
다시 설명하면, 회전돌기부(230)는 길이방향으로 연장되어 원기둥형상으로 형성된다. 그리고 하부에 볼베어링이 형성되어 원기둥이 수직한 축을 중심으로 회전될 수 있다.In other words, the rotation protrusion 230 extends in the longitudinal direction and is formed in a cylindrical shape. In addition, a ball bearing is formed in the lower part so that the cylinder can be rotated around a vertical axis.
이로 인해, 회전판(220)의 회전으로 위빙와이어(240)가 회전돌기부(230)에 감기는 것을 방지해준다.Accordingly, the weaving wire 240 is prevented from being wound around the rotating protrusion 230 due to the rotation of the rotating plate 220.
위빙와이어(240)는 회전돌기부(230)와 일측이 연결되고, 타측이 텅스텐 전극봉(11)에 연결되어 회전판(220)의 회전에 따라 콜렛바디부(120)를 위빙 시킨다.The weaving wire 240 has one side connected to the rotating protrusion 230 and the other side connected to the tungsten electrode 11 to weave the collet body 120 according to the rotation of the rotating plate 220.
이때, 위빙와이어(240)는 편심 회전하는 회전판(220)의 일면에 돌출된 회전돌기부(230)에 연결되어 회전판(220)의 회전에 대응하여 콜렛바디부(120)를 잡아당기거나 느슨하게 해준다.At this time, the weaving wire 240 is connected to the rotating protrusion 230 protruding from one surface of the rotating plate 220 that rotates eccentrically, and pulls or loosens the collet body part 120 in response to the rotation of the rotating plate 220.
일례로, 도 4 및 도 5에 도시된 바와 같이 위빙와이어(240)는 회전판(220)이 일방향으로 회전 시 회전돌기부(230)가 콜렛바디부(120)로부터 이격되면 콜렛바디부(120)를 회전판(220)의 방향으로 잡아당긴다.For example, as shown in FIGS. 4 and 5, when the rotating plate 220 is rotated in one direction, the weaving wire 240 is separated from the collet body 120 when the rotating protrusion 230 is separated from the collet body 120. Pull in the direction of the rotating plate 220.
그리고 위빙와이어(240)는 회전판(220)이 회전하여 회전돌기부(230)가 콜렛바디부(120)에 인접하면, 외빙와이어(240)가 느슨해진다. 이때, 탄성부(260)가 콜렛바디부(120)를 잡아당겨 회전판(220)으로부터 이격되게 한다.And, in the weaving wire 240, when the rotating plate 220 rotates and the rotation protrusion 230 is adjacent to the collet body 120, the outer ice wire 240 is loosened. At this time, the elastic part 260 pulls the collet body part 120 to be spaced apart from the rotating plate 220.
위빙판(250)은 중앙이 관통된 판 형상으로 형성되고, 바디관(110)의 내부에 위치하여 텅스텐 전극봉(11)의 위빙축이 된다.The weaving plate 250 is formed in the shape of a plate having a center penetrating it, and is located inside the body tube 110 to become a weaving axis of the tungsten electrode 11.
다시 설명하면, 위빙판(250)은 콜렛바디부(120)의 외주면을 따라 소정의 두께를 가지는 플랜지로 형성된다. 그리고 바디관(110)의 내부에 형성된 홈에 끼워진다.In other words, the weaving plate 250 is formed of a flange having a predetermined thickness along the outer circumferential surface of the collet body 120. And it is fitted into the groove formed in the interior of the body tube (110).
이때, 위빙판(250)은 콜렛바디부(120)를 위빙와이어(240)가 일방향으로 잡아당기고 탄성부(260)가 다른방향으로 잡아당기면서 위빙현상이 일어나는 축의 역할을 하게 된다.At this time, the weaving plate 250 serves as an axis in which the weaving phenomenon occurs as the weaving wire 240 pulls the collet body part 120 in one direction and the elastic part 260 pulls it in the other direction.
탄성부(260)는 바디관(110)의 내측과 콜렛바디부(120)의 외측 사이에 위치하여 일방향으로 회전된 콜렛바디부(120)를 원래 위치로 복귀시키는 역할을 한다.The elastic part 260 is located between the inner side of the body tube 110 and the outer side of the collet body part 120 and serves to return the collet body part 120 rotated in one direction to its original position.
이와 같이 위빙부(200)는 텅스텐 전극봉(11)을 일정간격으로 위빙되게 하여 반복적인 손목돌림을 통해 용접 비드 간격을 작업자의 느낌 또는 업무의 경험으로 작업하는 것을 방지해준다. 그리고 반복작업으로 인한 손목이나 어깨에 무리를 주고 통증을 유발하는 것을 방지해준다.As described above, the weaving unit 200 prevents the tungsten electrode 11 from being weaved at regular intervals, thereby preventing the welding bead interval from working with the feeling of a worker or the experience of work through repetitive wrist rotation. In addition, it prevents stress on the wrist or shoulder caused by repetitive work and causes pain.
도 1을 참조하면, 작동부(300)는 위빙부(200)의 작동을 제어하는 역할을 한다.Referring to FIG. 1, the operation unit 300 serves to control the operation of the weaving unit 200.
이러한 작동부(300)는 동작레버(310), 속도제어레버(320) 및 스위치(330)를 더 포함한다.This operation unit 300 further includes an operation lever 310, a speed control lever 320, and a switch 330.
동작레버(310)는 전동모터(210)에 전원을 인가하여 전동모터(210)를 동작시킨다. 이를 위해, 손잡이(13)의 내부에 배터리 또는 전원선을 연결하는 커넥터를 형성시키는 것이 바람직하다.The operation lever 310 applies power to the electric motor 210 to operate the electric motor 210. To this end, it is preferable to form a connector for connecting the battery or power line inside the handle 13.
속도제어레버(320)는 전동모터(330)의 회전속도를 제어하고, 손잡이(13)의 외주면 일측에 배치된다. 즉, 속도제어레버(320)는 전동모터(330)의 회전속도를 작업자의 작업속도에 대응하여 회전되게 하여 텅스텐 전극봉(11)의 위빙을 작업자의 속도에 대응되게 한다.The speed control lever 320 controls the rotational speed of the electric motor 330 and is disposed on one side of the outer peripheral surface of the handle 13. That is, the speed control lever 320 rotates the rotational speed of the electric motor 330 corresponding to the working speed of the operator, so that the weaving of the tungsten electrode 11 corresponds to the operator's speed.
스위치(330)는 속도제어레버(320)에 인접하여 배치되고, 아크를 발생시키는 역할을 한다.The switch 330 is disposed adjacent to the speed control lever 320 and serves to generate an arc.
이를 위해, 손잡이(13)의 내측에 불활성가스가 주입되는 주입관이 형성된다.(미도시)To this end, an injection tube into which an inert gas is injected is formed inside the handle 13 (not shown).
