상기한 이산화탄소 로봇 용접기는 토치노즐에서 나오는 용접봉으로 모재에 일정량 용접을 하게 되면 용접봉의 끝부분에 구슬모양의 용접 부산물이 생기게 되고 이렇게 용접 부산물이 생기게 되면 용접불량의 원인이 되기 때문에 일정량 용접을 한 후에는 용접봉의 끝부분에 형성된 구슬모양의 용접 부산물을 제거하는 작업을 하게 된다.The carbon dioxide robot welding machine is a welding rod coming out of the torch nozzle. When a certain amount of welding is made to the base metal, a bead-shaped welding byproduct is formed at the end of the welding rod. Is to remove the bead-shaped welding by-product formed at the end of the electrode.

종래 이산화탄소 로봇 용접기에 설치되어 용접봉의 끝부분에 형성된 구슬모양의 용접 부산물을 제거하기 위한 용접봉 절단기가 개시되고 있다.Conventional welding machine for removing the bead-shaped welding by-products installed at the end of the electrode installed in the carbon dioxide robot welding machine has been disclosed.

그런데, 용접봉 절단기에 설치되어 있는 커팅날이 한개로 구성되어 있기 때문에 수시로 교환해야하는 불편이 있을 뿐만 아니라 커팅날을 교체할 때에는 용접을 할 수 없기 때문에 작업의 지연이나 중단으로 인한 생산성이 떨어지는 것은 물론이고, 커팅날을 교체하는 시기가 늦어지면, 구슬모양으로 형성된 용접 부산물로 인해 용접 불량이 발생하여 용접물의 품질이 떨어지거나 용접물을 제품으로 사용할 수 없게 됨으로써 경제적인 손실로 이어지는 등 용접봉 절단기의 구조에 많은 문제점이 있다. However, since the cutting blade installed in the welding rod cutter is composed of one, it is not only inconvenient to replace it at any time, but also the welding is not possible when the cutting blade is replaced. If the cutting edge is delayed, the welding by-products formed in the shape of beads may cause welding defects, resulting in poor quality of the welds or economical loss of the welds. There is a problem.

Position indicator (8) formed with two or more guide grooves (8 ') is installed to be coupled to the guide protrusion (5') formed on the stopper (5).

도면의 미설명 부호 50은 용접기, 51은 용접봉, 52는 볼트, 53는 에어호스, 54는 토치노즐, 55는 용접 부산물을 표시한 것이다.In the drawings, reference numeral 50 denotes a welding machine, 51 a welding rod, 52 a bolt, 53 an air hose, 54 a torch nozzle, and 55 a welding by-product.

상기와 같이 구성된 이산화탄소 로봇 용접기용 용접봉 절단기의 작용을 살펴보면 다음과 같다.Looking at the action of the electrode cutter for a carbon dioxide robot welder configured as described above are as follows.

이산화탄소 로봇 용접기용 용접봉 절단기는 토치노즐(54)의 작업 반경을 벗어나지 않게 설치되는데, 실린더(1)에 고정되어 있는 브라켓(4)을 이용하여 용접기(50)에 볼트(520로 고정설치한다.The welding rod cutter for the carbon dioxide robot welding machine is installed without leaving the working radius of the torch nozzle 54, and is fixed to the welding machine 50 by bolts 520 using the bracket 4 fixed to the cylinder 1.

상기와 같이 설치한 상태에서 용접을 하게 되며, 토치노즐은 미리 작성된 프로그램에 의해 모재의 용접부위로 근접 후, 용접봉(51)이 토치노즐(54)에서 공급되고, 용접봉이 용융되면서 용접이 된다.The welding is performed in the installed state as described above, the torch nozzle is approached to the welding site of the base material by a pre-written program, the welding rod 51 is supplied from the torch nozzle 54, and the welding rod is welded while melting.

이러한 용접과정이 지속되면서 용접봉의 끝부분에 구슬모양의 용접 부산물이 형성되고, 상기와 같은 용접 부산물은 용접불량이 되기 때문에 용접봉의 끝부분을 절단하여 용접 부산물을 제거해야 한다.As the welding process continues, a bead-shaped welding by-product is formed at the end of the electrode, and the welding by-product as described above becomes a welding defect, so that the welding by-product is removed by cutting the end of the electrode.

상기와 같은 용접 부산물을 제거하기 위하여 프로그램에 의해서 토치노즐(54)이 용접봉 절단기로 이동하여 실린더(1)의 앞쪽에 있는 관체형 받침구(3)에 형성된 삽입구멍(2)으로 용접 부산물이 형성된 용접봉(51)을 삽입시킨다.(도3참조)In order to remove the welding by-products described above, the torch nozzle 54 is moved to the electrode cutting machine by a program, and the welding by-products are formed by the insertion holes 2 formed in the tubular support 3 in the front of the cylinder 1. Insert the electrode 51 (see Fig. 3).

그러면, 실린더의 작동으로 실린더 내부에 설치되어 있는 피스톤(6)이 앞쪽에 설치된 환봉형 커팅날(7)과 함께 전진하여 환봉형 커팅날(7)이 관체형 받침구(3)에 형성된 삽입구멍(2)으로 진입된 용접봉의 끝부분을 절단하여 용접 부산물을 제거하고 최초의 상태로 복귀하는데, 이때 위치표시구(8)에 형성된 안내홈(8')이 스토퍼(5)에 형성된 안내돌기(5')를 따라 전후진하게 되므로 관체형 받침구(3)의 내부에 슬라이드되는 환봉형 커팅날(7)이 정확하게 슬라이딩하게 된다.(도4참조)Then, by the operation of the cylinder, the piston 6 installed inside the cylinder is advanced with the round bar-shaped cutting blade 7 provided at the front so that the round bar-shaped cutting blade 7 is formed in the tubular support 3. Cutting the end of the welding rod entered into the (2) to remove the welding by-products and return to the initial state, wherein the guide groove (8 ') formed in the position indicator (8) is formed in the stopper (5) 5 '), the rod-shaped cutting blade 7 slid inside the tubular support 3 is slid precisely (see FIG. 4).

한편, 토치노즐은 프로그램에 의해서 다시 모재의 용접부위로 근접하여 용접 작업을 하게 되고, 용접봉에 형성되는 용접 부산물을 제거할 시점이 되면 프로그램에 의해서 토치노즐(54)이 용접봉 절단기로 이동하여 관체형 받침구(3)에 형성된 삽입구멍(2)으로 용접 부산물이 형성된 용접봉(51)을 삽입시켜 용접봉을 절단하는 작업을 하게 된다.On the other hand, the torch nozzle is welded to the welding part of the base material again by the program, and when it is time to remove the welding by-products formed in the electrode, the torch nozzle 54 moves to the electrode cutter by the program to support the tubular bearing. The welding rod 51 is formed by inserting the welding rod 51 having the welding by-product into the insertion hole 2 formed in the sphere 3 to cut the welding rod.

상기와 같이 용접봉을 절단하는 작업을 반복하게 되면, 관체형 받침구(3)에 형성된 삽입구멍이 넓어지거나 절단부분이 마모되며, 또 내부에 슬라이드 되게 설치된 환봉형 커팅날(7)도 마모된다.When the operation of cutting the welding rod as described above is repeated, the insertion hole formed in the tubular support 3 is widened or the cut portion is worn, and the round bar-shaped cutting blade 7 installed to slide therein is also worn.

그러면, 실린더의 앞쪽에 설치된 관체형 받침구(3)를 이동시켜 사용하지 않은 쪽에 있는 삽입구멍(2)을 상부로 이동시켜준다.Then, the tubular support 3 installed in the front of the cylinder is moved to move the insertion hole 2 in the unused side to the upper portion.

그리고, 관체형 받침구(3)의 내부에 슬라이드 되게 설치된 환봉형 커팅날(7)의 위치도 이동시켜야 하는데, 이때 안내돌기(5')가 형성된 스톱퍼(5)를 분리하고 피스톤(6)에 설치되어 있는 위치표시구(8)를 돌려주고, 상기 위치표시구(8)에 형성된 안내홈(8')에 스톱퍼(5)에 형성된 안내돌기(5')을 결합하고 스톱퍼(5)를 최초의 위치에 설치하면 된다.In addition, the position of the round bar-shaped cutting blade 7 installed to slide in the tubular support 3 is also to be moved. At this time, the stopper 5 in which the guide protrusion 5 'is formed is removed and the piston 6 is attached to the piston 6. Turn the installed position indicator (8), the guide groove (8 ') formed in the position indicator (8) is coupled to the guide projection (5') formed on the stopper (5) and the stopper (5) first You can install it at the position of.

그러면, 위치표시구(8)와 피스톤(6)에 의해서 연결되어 있는 환봉형 커팅날(7)이 위치표시구(8)와 같이 돌아가기 때문에 환봉형 커팅날(7)의 사용한 부분이 중복되지 않고 사용하지 않은 부분으로 정확하게 이동시킬 수 있다.Then, since the round bar-shaped cutting blade 7 connected by the position indicator 8 and the piston 6 is turned like the position indicator 8, the used portions of the round bar-shaped cutting blade 7 do not overlap. Can be moved accurately to unused parts.
