Description
본 발명은 스폿 용접기(Spot Welding Machine)용 팁 드레서(Tip Dresser)에 관한 것으로, 더욱 상세히는 종래에는 스폿 용접기의 팁에 형성된 산화 피막(Oxidation Film)을 제거하기 위해 줄(File)을 사용함으로 인한 단점을 보완하기 위해 개발된 스폿 용접기용 팁 드레서에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tip dresser for a spot welding machine, and more particularly, by using a file to remove an oxide film formed on a tip of a spot welder. The present invention relates to a tip dresser for a spot welder, which was developed to compensate for the shortcomings.
일반적으로, 용접은 2개 또는 여러개의 금속을 가연성 가스 또는 아크 열을 이용하여 국부적으로 용융시켜 접합시키는 야금적인 접합법을 말하며, 그 종류에는 가열방법에 따라 가스 용접, 전기 용접, 테르밋 용접이 있으며, 상기 전기 용접은 그 원리에 따라 아크 용접과 저항 용접으로 분류되며, 상기 저항 용접에는 스폿 용접과 시임 용접(Seam Welding)이 있다.In general, welding refers to a metallurgical joining method in which two or several metals are locally melted and joined by using flammable gas or arc heat, and the types thereof include gas welding, electric welding, and thermite welding. The electric welding is classified into arc welding and resistance welding according to the principle, and the resistance welding includes spot welding and seam welding.
상기 스폿 용접은 2개의 모재를 겹쳐놓고 대전류를 흐르게 하여, 상기 모재가 접촉 저항열에 의하여 용융될 때 압력을 가하여 접합하는 용접으로서, 자동차, 항공기 등에 많이 사용되며, 점 용접(點 鎔接)이라고도 한다. 상기 스폿용접은 6mm 이하의 판재의 용접에 적합하며, 두께 0.4∼3.2mm의 판재를 용접하는 것이 가장 능률적이다.The spot welding is a welding in which a large current flows while superposing two base materials, and the base material is welded by applying pressure when the base material is melted by contact resistance heat, and is widely used in automobiles, aircrafts, etc., and is also referred to as spot welding. . The spot welding is suitable for welding a sheet of 6 mm or less, and it is most efficient to weld a sheet of 0.4 to 3.2 mm in thickness.
상기 스폿용접을 실시하기 위해서는, 제 1 도에 개략적으로 도시된 바와같은 스폿 용접기를 사용한다. 스폿 용접기(1)는 전원(2)에 연결되어 전압을 변환하는 용접 변압기(3), 상기 용접 변압기(3)에 연결되어 모재(4)를 고정시키는 고정전극(5) 및 상기 용접 변압기(3)에 연결되어 소정의 압력(P)으로 상기 고정전극(5)의 반대편에서 상기 모재(4)를 가압하는 가동전극(6)을 포함하여 구성된다.In order to perform the spot welding, a spot welder as shown schematically in FIG. 1 is used. The spot welder 1 is a welding transformer 3 connected to a power source 2 to convert voltage, a fixed electrode 5 connected to the welding transformer 3 to fix the base material 4, and the welding transformer 3. And a movable electrode 6 which presses the base material 4 on the opposite side of the fixed electrode 5 to a predetermined pressure P.
상기 스폿 용접기(1)를 사용하여 반복적으로 용접 작업을 실시하면, 용접 작업시에 발생되는 고열로 인해 상기 고정전극(6)과 가동전극(6)의 말단부분인 팁(7,8)의 표면에 산화 피막이 형성된다. 상기 산화 피막은 용접기(1)의 성능을 저하시키고, 용접부위의 품질을 저하시키기 때문에 제거되어야 하는데, 종래에는 상기 산화 피막의 제거를 위해 제 2 도에 도시된 바와같은 줄을 사용하였다.When the welding operation is repeatedly performed using the spot welder 1, the surfaces of the tips 7 and 8, which are end portions of the fixed electrode 6 and the movable electrode 6 due to the high heat generated during the welding operation, are performed. An oxide film is formed on it. The oxide film should be removed because it degrades the performance of the welder 1 and degrades the quality of the welded area. Conventionally, a string as shown in FIG. 2 is used to remove the oxide film.
그런데, 줄을 사용하여 산화 피막을 제거하면, 작업이 불편할 뿐만 아니라, 산화 피막을 제거한 후 팁의 형상이 균일하지 못하며, 마모되어 제거되는 팁의 소모량이 많아져 용접기의 수명을 단축시키는 문제점이 있었다.However, if the oxide film is removed using a file, the work is not only inconvenient, but the shape of the tip is not uniform after the oxide film is removed. .
그러므로, 본 발명의 목적은 스폿 용접기의 팁에 형성된 산화 피막을 용이하고 균일하게 제거하기 위한 스폿 용접기용 팁 드레서를 제공하는 것이다.Therefore, an object of the present invention is to provide a tip dresser for a spot welder for easily and uniformly removing an oxide film formed on the tip of the spot welder.
제 1 도는 일반적인 스폿 용접기의 구조를 보여주는 구성도.1 is a block diagram showing the structure of a typical spot welder.
제 2 도는 스폿 용접기 전극의 팁에 형성된 산화 피막을 종래의 방식으로 제거하기 위해 사용되는 줄의 사시도.2 is a perspective view of a string used to remove an oxide film formed at the tip of a spot welder electrode in a conventional manner.
제 3 도는 본 발명에 따른 스폿 용접기용 팁 드레서의 구조를 보여주는 정면도.3 is a front view showing the structure of the tip dresser for a spot welder according to the present invention.

제 3 도에는 본 발명에 따른 스폿 용접기용 팁 드레서의 구조를 보여주는 도면이 정면도로 도시되어 있다. 도면에 도시된 바와같이, 본 발명에 따른 스폿 용접기용 팁 드레서는 콤프레서의 공기압으로 작동되는 에어 건(10)의 회동부(11)에 반구형 본체(12)가 장착되고, 상기 반구형 본체(12)는 열전도성이 우수한 재질의 금속으로 형성되며, 상기 반구형 본체(12)의 내측에는 입도가 곱고 강도가 강한 마모재(13)가 도포되어 구성된다.3 is a front view showing a structure of a tip dresser for a spot welder according to the present invention. As shown in the figure, the spot dresser tip dresser according to the present invention is mounted on a hemispherical body 12 to the rotating part 11 of the air gun 10 operated by the air pressure of the compressor, the hemispherical body 12 Is formed of a metal of excellent thermal conductivity, the hemispherical body 12 is composed of a wear material 13 having a high particle size and strong strength is applied to the inside.
상기 본체(12)는 열전도성이 우수한 알루미늄(Aluminum) 재질로 형성되는 것이 바람직하다The body 12 is preferably formed of aluminum (Aluminum) material excellent in thermal conductivity.
스폿 용접기(1)를 사용하여 수 차례의 용접작업을 실시하여, 상기 스폿 용접기(1) 고정전극(5)과 가동전극(6)의 팁(7,8)에 산화 피막이 형성되면, 본 발명에 따른 스폿 용접기용 팁 드레서를 사용하여 상기 산화 피막을 드레싱한다. 드레싱 작업을 하기 위해서는 상기 드레서의 본체(12)의 내측을 상기 팁(7,8)에 접촉 배치시킨 후, 상기 에어 건(10)을 작동시키면, 상기 본체(12)가 회전하면서 상기 본체(12)의 내측에 도포된 마모재(13)의 작용으로 상기 산화 피막이 제거된다.When a number of welding operations are performed by using the spot welder 1, and an oxide film is formed on the tips 7, 8 of the fixed electrode 5 and the movable electrode 6 of the spot welder 1, The oxide film is dressed using a tip dresser for spot welders according to the invention. In order to perform the dressing operation, the inner side of the main body 12 of the dresser is placed in contact with the tips 7 and 8, and then the air gun 10 is operated to rotate the main body 12 while the main body 12 rotates. The oxide film is removed by the action of the wear material 13 applied on the inside.
상기 드레서를 사용하여 팁(7,8)에 형성된 산화 피막을 드레싱하면, 드레싱 작업 후, 상기 팁(7,8)의 곡률값이 크게 변화하지 않으며, 드레싱되는 팁(7,8) 자체의 소모량도 최소화할 수 있다.When dressing the oxide film formed on the tips (7, 8) using the dresser, after the dressing operation, the curvature value of the tips (7, 8) does not change significantly, the consumption amount of the tips (7, 8) to be dressing itself Can also be minimized.
결국, 본 발명에 따른 스폿 용접기용 팁 드레서를 사용하면, 스폿 용접기의 팁에 형성된 산화 피막을 용이하고 균일하게 제거할 수 있는 잇점이 있다.As a result, the use of the tip dresser for a spot welder according to the present invention has the advantage that the oxide film formed on the tip of the spot welder can be easily and uniformly removed.
이상에서 본 발명에 따른 바람직한 실시예에 대해 설명하였지만, 본 기술분야의 당업자라면 첨부된 특허청구의 범위를 벗어남이 없이 다양한 변형예 및 수정예를 실시할 수 있을 것으로 이해된다.While preferred embodiments of the present invention have been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.
