동관 자동용접장치Copper tube automatic welding device

본 발명은 해당 동관의 원주이음매를 용접할 때 외부에 돌출된 용접접지선과 가스호스가 꼬이지않고 360˚회전되면서 수평방향으로 정확히 해당 동관을 용접할 수 있는 동관 자동용접장치에 관한 것이다.The present invention relates to a copper tube automatic welding device capable of welding the copper tube exactly in the horizontal direction while rotating 360 ° without twisting the welding ground wire and the gas hose protruding to the outside when welding the circumferential joint of the copper tube.

시대가 복잡해지고 과학기술이 발전됨에 따라 공장자동화와 더불어 생산라인의 장비도 다각적으로 개발되어 사용하고 있다. 생산라인의 장비중에는 용접장치로는 예컨대 철판, 동판 또는 PVC 등을 필요한 결합상태로 만들기 위해 해당 부분을 용접할 수 있도록 되어 있다. 그러나, 이들 재질 등을 용접하다 보면 재질 특성이 다른 경우나 어려운 모양들이 접하게 되는 바, 이를 보다 정확하고 손쉽게 용접을 하기 위해서는 특수한 목적의 용접장치가 개발되어 사용되게 된다.As the times become more complex and science and technology develop, as well as factory automation, the equipment of production lines has been developed and used in various ways. Among the equipment in the production line, the welding device is capable of welding the corresponding parts, for example, iron plate, copper plate or PVC to make the required bonding state. However, when welding these materials, such as when the material characteristics are different or difficult shapes are encountered, in order to weld more precisely and easily, a special purpose welding apparatus is developed and used.

특수한 용접장치중 각기 재질이 다른, 즉 철판 몸체내에 동관의 원주이음매를 용접하게 되는 용접장치는 외부로 알곤가스를 공급해주는 가스호스와 아크발생을 위한 용접접지선 등을 이용하게 된다. 해당 동관 용접시 용접할 도관의 외경에 따라 360˚회전하면서 상기 가스호스와 용접접지선으로부터의 알곤가스 송출 및 아크발생에 따라 정확한 동관용접이 이루어지게 된다.The welding device that welds the circumferential joint of copper tube in the iron plate body of different special welding device uses the gas hose which supplies argon gas to the outside and the welding ground wire for arc generation. When the copper tube is welded, the copper tube is rotated 360 ° according to the outer diameter of the conduit to be welded, so that the accurate copper tube welding is performed by argon gas delivery and arc generation from the gas hose and the welding ground line.

이상과 같이 작동되는 동관용접장치는 수평방향으로 360˚회전을 따라 용접하게 되므로 그 내부구조가 복잡할 뿐만아니라 고가로 제작되고 있고, 또한 외부로 나오게 되는 가스호스와 용접접지선이 용접회전시 꼬이지 않도록 하는 방법 등을 고려하여 제작하고 있다.The copper pipe welding device operated as described above is welded along the 360 ° rotation in the horizontal direction, and its internal structure is not only complicated, but also expensive, and the gas hose and the welding ground wire coming out are not twisted during the welding rotation. Considering how to produce.

본 발명은 상기와 같은 사정 등을 감안하여 발명한 것으로, 용접 헤드몸체에 내장된 모터로 회전되는 샤프트내의 가스호스와 회전 및 고정용 카본브러쉬에 접속되는 용접접지선의 용접전극봉이 해당 동관의 원주 이음매를 수평방향으로 용접될 때 360˚ 회전된다해도 이들이 서로 꼬이지 않고 같이 회전하게 되어 상기 용접접지선의 용접스파크와 가스호스의 가스온/오프에 따른 동관원주 이음매의 자동용접을 간편하고 정확하게 수행할 수 있는 동관 자동용접장치를 제공함에 그 목적이 있다.The present invention has been invented in view of the above circumstances, and the welding electrode of the welding ground wire connected to the gas hose in the shaft rotated by the motor embedded in the welding head body and the carbon brush for rotation and fixation is the circumferential joint of the copper tube. When they are rotated 360˚ when they are welded in the horizontal direction, they are rotated together without being twisted together, so that the welding welding of the welding ground wire and the gas pipe on / off of the gas hose can be easily and accurately performed on the copper pipe circumferential joint. The purpose is to provide a copper tube automatic welding device.

제1도는 본 발명의 실시예에 관한 동관 자동용접장치를 도시해 놓은 구성도로서, 본 발명의 동관 자동용접장치는 용접 헤드몸체(8)의 앞단에 놓여지는 해당 동관의 원주이음매를 용접할 때, 제3도에 도시된 바와 같이 내장된 모터(9)로 회전되어 샤프트(11)의 가스호스(6)와 회전용 카본부러쉬(12)의 용접접지선(5)이 외부에서 서로 꼬이지 않고 360˚회전됨으로 용접전극봉(16)의 수평방향으로 해당 동관 이음매의 자동용접이 행해지도록 되어 있다.1 is a block diagram showing a copper tube automatic welding device according to an embodiment of the present invention, the copper tube automatic welding device of the present invention when welding the circumferential joint of the copper tube placed on the front end of the welding head body (8) As shown in FIG. 3, the gas hose 6 of the shaft 11 and the welding ground wire 5 of the rotary carbon brush 12 are rotated 360 degrees without being twisted with each other. As it rotates, automatic welding of the copper tube joint is performed in the horizontal direction of the welding electrode 16.

상기 용접헤드몸체(8)의 작동을 제어 및 통제하는 제어장치(1)에는 3상 220V의 알곤가스통(2)이 연결되면서 용접접지선(5), 가스호스(6) 및 전선(7)을 통해 용접헤드몸체(8)가 연결된다.The control device 1 for controlling and controlling the operation of the welding head body 8 is connected to a three-phase 220V argon gas cylinder 2 through a welding ground wire 5, a gas hose 6, and an electric wire 7. The welding head body 8 is connected.

상기 용접헤드몸체(8)의 푸쉬버튼스위치(15)측에는 전선(7)으로 연결된 스피드조종반(4)을 통해 페달스위치(3)가 연결되는바, 상기 푸쉬버튼스위치(15)는 용접접지선(5)의 용접스파크와 가스호스(6)의 가스온/오프를 조정하게 되고, 상기 페달 스위치(3)는 용접헤드몸체(8)내의 모터(9)내에 결합된 샤프트(11)의 회전을 온/오프로 조정하게 된다.The push button switch 15 of the welding head body 8 is connected to the pedal switch 3 through a speed control panel 4 connected by an electric wire 7, and the push button switch 15 is a welding ground wire ( 5) to adjust gas on / off of the welding spark and gas hose (6), the pedal switch (3) turns on the rotation of the shaft (11) coupled in the motor (9) in the welding head body (8). Toggle on / off.

따라서, 상기 페달스위치(3)와 푸쉬버튼스위치(15)에 의해 작동되는 용접헤드몸체(8)는, 제3도에 도시된 모터(9)를 구동시킴에 따라 내부 샤프트(11)와 회전용 카본부러쉬(12)가 360˚회전되면서 외부로 나온 용접접지선(5)과 가스호스(6)가 꼬이지 않고 용접전극봉(16)이 회전되어 수평방향으로 해당 동관 원주이음매를 자동으로 용접해주게 된다.Accordingly, the welding head body 8 operated by the pedal switch 3 and the push button switch 15 rotates the inner shaft 11 and rotates as the motor 9 shown in FIG. 3 is driven. As the carbon brush 12 is rotated 360 degrees, the welding ground wire 5 and the gas hose 6, which are outward, are not twisted, and the welding electrode 16 is rotated to automatically weld the corresponding copper tube circumferential joint in the horizontal direction.

즉, 제2도 및 제3도에 도시된 용접헤드몸체(8)에는 모터(9)가 내장되어 있고, 이 모터(9)축에는 가스통로(10)가 형성되어 있는 샤프트(11)가 결합되어 앞쪽으로 용접전극봉(16)이 형성되어 있다. 상기 샤프트(11)와 용접전극봉(16)사이에는 가스통로(10)측을 통과한 가스호스(6)가 외부로 나와서 이를 연결해 주고, 상기 샤프트(11)의 전면에 오링(17)을 매개로 회전용 카본부러쉬(12)와 고정용 카본부러쉬(13)가 각각 결합된다. 여기서, 상기 샤프트(11)의 전면에 오링(17)을 매개로 회전용 카본부러쉬(12)와 고정용 카본부러쉬(13)가 각각 결합된다. 여기서, 상기 샤프트(11)에는 모터(9)가 회전할 때 원활한 회전을 위해 앞뒤로 베어링(18, 18')이 각각 설치된다.That is, the welding head body 8 shown in FIGS. 2 and 3 has a motor 9 embedded therein, and the shaft 11 on which the gas passage 10 is formed is coupled to the motor 9 shaft. As a result, a welding electrode 16 is formed forward. Between the shaft 11 and the welding electrode 16, the gas hose 6 passing through the gas passage 10 side to the outside and connected to the outside, through the O-ring 17 on the front of the shaft 11 The rotary carbon brush 12 and the fixed carbon brush 13 are combined, respectively. Here, the rotary carbon brush 12 and the fixing carbon brush 13 are respectively coupled to the front surface of the shaft 11 via the O-ring 17. Here, the shafts 11 are provided with bearings 18 and 18 ', respectively, for smooth rotation when the motor 9 rotates.
