Description
본 고안은 CO2용접기용 토치바디(Torch Body)에 관한 것으로, 더욱 상세하게는 토치바디와 토치케이블(Torch cable) 연결부(Grip)에서의 실링 효과를 높여 가스누기 억제에 완벽성을 추구하고, 장기간 사용으로 인해 토치바디 피복과 토치그립부의 간섭을 줄일 수 있도록 개선된 토치바디를 제공함에 있는 것이다.The present invention relates to a torch body for a CO 2 welding machine, and more specifically, to improve the sealing effect at the torch body and the torch cable (Grip) to pursue perfection to suppress gas leakage, It is to provide an improved torch body to reduce the interference of the torch body and the torch grip portion due to long-term use.
도 1에서와 같이 범용 CO2용접기에 있어, 용접용 토치 건(Torch Gun)(10)의 토치케이블(Torch cable)(20)과 노즐(nozzle)(30) 사이에 토치바디(Torch Body)가 설치되어 토치케이블(20)을 통해 공급되는 가스가 토치바디(40)를 경유하여 노즐(30)에 공급되도록 구성함으로써 용접복사열이 손으로 전이되는 것을 감소시키도록 되어 있다.In the general-purpose CO 2 welding machine as shown in FIG. 1, a torch body is disposed between the torch cable 20 and the nozzle 30 of the torch gun 10 for welding. By installing the gas supplied through the torch cable 20 to be supplied to the nozzle 30 via the torch body 40, the welding radiation heat is reduced by hand.
종래에는 토치케이블(20)이 결합되는 토치바디(40)의 콘넥터 연결부(41)에 O-링홈(43)을 형성하여 상기 O-링홈(43)에 삽입되는 O-링(50)에 의해 용접보호가스의 누기를 최소화시키도록 실링하고 있다.Conventionally, the O-ring groove 43 is formed in the connector connection portion 41 of the torch body 40 to which the torch cable 20 is coupled, and welded by the O-ring 50 inserted into the O-ring groove 43. It is sealed to minimize leakage of protective gas.
하지만 토치바디(40)의 콘넥터 연결부(41) 가공시 조임 절개부가 길고, 하나의 O-링(50)만이 삽입되는 O-링홈(43)이 형성되고 있어 상기 O-링홈(43)에 삽입되는 O-링(50)만으로는 용접보호가스의 누기를 최소화하기에는 다소 미흡하여 이들 연결부(41)를 통한 가스누기에 적절하게 대응하지 못한다는 결점을 안고 있다.However, when the connector connection part 41 of the torch body 40 is processed, the tightening cutout is long, and an O-ring groove 43 into which only one O-ring 50 is inserted is formed, thereby being inserted into the O-ring groove 43. O-ring 50 alone is somewhat insufficient to minimize the leakage of the welding protection gas has a drawback that does not adequately respond to the gas leakage through these connections (41).
또한, 용접건의 장기간 사용시에는 토치바디(40)와 서로 결합되는 토치케이블(20)의 결합부가 쉽게 손상되어 그 정도가 심한 경우에는 절연피복이 벗겨져 감전사고를 야기하기도 하였다.In addition, when the welding gun is used for a long time, the torch body 40 and the coupling part of the torch cable 20 coupled to each other are easily damaged, and when the degree is severe, the insulation coating is peeled off, causing an electric shock accident.
상기한 종래의 문제점은 토치바디(40)에 결합되는 토치케이블(20)이 용접시 발생되는 열에 의해 피복튜브(합성고무)의 팽창으로 헐거워지거나 길이가 늘어나 토치케이블이 완벽하게 체결되지 않는데서 비롯되었던 것이다.The conventional problem is that the torch cable 20 coupled to the torch body 40 is loosened due to the expansion of the coated tube (synthetic rubber) due to heat generated during welding, or the length thereof is increased so that the torch cable is not completely fastened. It would have been.
본 고안은 상기한 바와 같은 종래의 문제점을 감안 해소함을 그 목적으로 하는 것으로, 토치케이블(Torch cable)이 결합되는 토치바디의 콘넥터 연결부에서의 보다 완벽한 실링으로 용접보호 가스누기를 최소화하면서 사용중 토치바디에 의해 토치케이블의 절연피복이 벗겨지는 것을 예방할 수 있도록 개선된 구조를 갖는 토치바디를 제공함에 그 목적이 있다.The object of the present invention is to solve the conventional problems as described above, and torch body in use while minimizing welding protection gas leakage by more perfect sealing at the connector connection of the torch body to which the torch cable is coupled. It is an object of the present invention to provide a torch body having an improved structure to prevent the insulation coating of the torch cable from being peeled off.
상기한 목적 달성을 위해 본 고안은 토치케이블과 노즐 사이에 토치바디가 결합되는 CO2용접기의 용접용 토치건에 있어서, 상기 토치바디는 2개의 O-링홈이 설치되어 이들 각각에 끼워지는 O-링에 의해 이중으로 실링되는 컨넥터 연결부와, 상기 콘넥터 연결부의 안쪽면에 토치케이블의 선단과 접촉하도록 된 스토퍼가 구비되는 것을 그 특징으로 하고 있다.In order to achieve the above object, the present invention is a welding torch gun of a CO 2 welder in which a torch body is coupled between a torch cable and a nozzle, and the torch body has two O-ring grooves installed therein. A connector connection part double-sealed by a ring and a stopper on the inner side of the connector connection part are provided to contact the tip of the torch cable.
이하, 본 고안을 첨부된 예시 도면을 참고하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

이에 도시된 바와 같이 본 고안은 토치케이블(20)과 노즐(30) 사이에 토치바디(40)가 결합되는 CO2용접기의 용접용 토치건(10)에 있어서, 상기 토치바디(40)의 컨넥터 연결부(41)에 2개의 O-링홈(43a,43b)을 설치하여 이들 각각에 O-링(50a,50b)이 끼워지도록 구성되어 토치바디(40)와 토치케이블(20)이 결합되는 연결부가 상기 O-링(50a,50b)에 의한 이중 실링 구조를 이루도록 구성됨을 특징으로 하고 있다.As shown in the present invention, in the torch gun 10 of the welding of the CO 2 welding machine that the torch body 40 is coupled between the torch cable 20 and the nozzle 30, the connector of the torch body 40 Two O-ring grooves 43a and 43b are installed in the connection portion 41 so that the O-rings 50a and 50b are fitted to each of the connection portions 41 so that the torch body 40 and the torch cable 20 are coupled to each other. It is characterized in that it is configured to form a double sealing structure by the O-ring (50a, 50b).
또한, 본 고안은 토치바디(40)의 콘넥터 연결부(41)의 안쪽면에는 원주면을 따라 부분 돌출되는 스토퍼(47)가 설치되어 상기 스토퍼(47)가 토치바디(40)에 토치케이블(20)이 과도하게 끼워지는 것을 제어하는 한편, 토치케이블(20)의 선단이 토치바디(40)와 접촉하는 것을 사전 예방하도록 구성됨을 특징으로 하고 있다.In addition, the present invention is provided with a stopper 47 which protrudes along the circumferential surface of the inner surface of the connector connection portion 41 of the torch body 40, the stopper 47 is a torch cable 20 to the torch body 40 ) Is excessively fitted, while the front end of the torch cable 20 is characterized in that it is configured to prevent the contact with the torch body 40 in advance.
이와 같이 구성된 본 고안은 토치케이블(20)과 노즐(30)사이에 결합되어 용접복사열이 손으로 전이되는 것을 감소시키도록 설치되는 토치바디(40)의 콘넥터 연결부(41)에 최소한 두개의 O-링홈(43a,43b)이 나란하게 형성되고 있어 이들 각각에는 O-링(50a,50b)이 차례로 끼워지도록 조립한다.The present invention configured as described above has at least two O-to the connector connection portion 41 of the torch body 40 which is coupled between the torch cable 20 and the nozzle 30 and installed to reduce the transfer of the welding radiation heat by hand. Ring grooves 43a and 43b are formed side by side, and each of them is assembled so that O-rings 50a and 50b are fitted in turn.
이처럼 두개의 O-링(50a,50b)이 결합된 콘넥터 연결부(41)에는 결합하고자 하는 토치케이블(20)의 한쪽 선단이 연결부(41)의 안쪽에 형성된 스토퍼(47)에 당접되어질 때까지 밀어 넣은 후 이들 연결부를 별도의 고정부재를 이용하여 고정되도록 견고하게 체결한다.In this way, the connector connecting portion 41 to which the two O-rings 50a and 50b are coupled is pushed until one end of the torch cable 20 to be coupled is brought into contact with the stopper 47 formed inside the connecting portion 41. After insertion, fasten these connections securely using a separate fixing member.
그리하면 토치바디(40)와 토치케이블(20)이 상호 결합되는 연결부(41)는 2개의 O-링(50a,50b)에 의한 이중 실링 구조를 이루게 되어 용접 열에 의해 토치케이블(20)이 일시적으로 늘어나거나 팽창되더라도 이들 연결부(41)는 소정의 간격을 두고 나란하게 설치되는 각각의 O-링(50a,50b)에 의한 이중 실링으로 보다 완벽한 실링효과를 도모할 수 있게되어 이들 연결부를 통한 가스누기를 최소화할 수 있게 된다.Then, the connecting portion 41 to which the torch body 40 and the torch cable 20 are coupled to each other forms a double sealing structure by two O-rings 50a and 50b so that the torch cable 20 is temporarily welded by welding heat. Even if it is stretched or expanded, these connecting portions 41 can achieve a more perfect sealing effect by double sealing by the respective O-rings 50a and 50b which are installed side by side at a predetermined interval so that the gas through these connecting portions can be achieved. This can minimize leakage.
그리고 토치바디(40)의 콘넥터 연결부(41)에 결합되는 토치케이블(20)은 그 안쪽에 형성되는 스토퍼(47) 까지만 결합되어 장기간 사용하더라도 토치케이블(20)의 선단이 토치바디(40)에 직접 부딪히거나 접촉되지 않지 아니하고 스토퍼(47)와 접촉하게 되므로 토치케이블(20)의 토치바디 결합부측이 절연피복 등이 쉽게 훼손 및 손상되는 것을 예방할 수 있는 것이다.The torch cable 20 coupled to the connector connecting portion 41 of the torch body 40 is coupled only to the stopper 47 formed therein so that the tip of the torch cable 20 is connected to the torch body 40 even if it is used for a long time. Since the contact with the stopper 47 without directly hitting or contacting the torch body coupling portion side of the torch cable 20 can prevent the insulation coating from being easily damaged or damaged.
이상에서 설명한 바와 같이 본 고안의 토치바디는 토치바디(40)와 토치케이블(20)이 상호 결합되는 콘넥터 연결부(41)가 2개의 O-링(50a,50b)에 의한 이중 실링 구조로 개선됨으로써 이들 연결부에서의 완벽한 실링도 가능하여 이들 연결부를 통한 가스누기를 최소화할 수 있게되어 가스비가 절감되는 이점이 있다.As described above, the torch body of the present invention is improved by a double sealing structure using two O-rings 50a and 50b in which the connector connection portion 41 to which the torch body 40 and the torch cable 20 are coupled to each other. Complete sealing at these connections is also possible, thereby minimizing gas leakage through these connections, thereby reducing the gas cost.
또한, 본 고안은 콘넥터 연결부의 안쪽에 별도의 스토퍼를 설치하여 상기 스토퍼에 토치케이블이 접촉함으로써 장기간 사용시에도 피복이 쉽게 훼손 및 손상되는 것을 예방할 수 있어 사용 수명연장에 크게 기여하는 등의 작용 효과를 갖는 매우 유용한 고안인 것이다.In addition, the present invention provides a separate stopper on the inside of the connector connection portion to prevent the coating from being easily damaged and damaged even during long-term use by contacting the torch cable to the stopper, thereby greatly contributes to the extended service life. It is a very useful design.
