상기와 같이 구성되어 있는 본 발명의 작용 관계를 설명하면 다음과 같다.Referring to the operational relationship of the present invention configured as described above are as follows.

본 발명의 튜브형 용접모재의 내면용접장치를 이용하여 튜브형태로 형성된 튜브형 용접모재의 내주연에 연속하여 용접을 하고자 할 경우에는 제일 먼저, 용접할 튜브형 용접모재를 들어올리면서 튜브형 용접모재의 일측 단부를 척(10)에 척킹시키면서 튜브형 용접모재의 타측 하단부를 용접모재지지롤러(18)로서 지지하여 튜브형 용접모재(20)가 본 발명의 튜브형 용접모재(20)의 내면용접장치에 수평상으로 장착한다.In order to continuously weld on the inner circumference of the tubular welding base material formed in the form of a tube using the inner surface welding apparatus of the tubular welding base material of the present invention, first, one end of the tubular welding base material is lifted while lifting the tubular welding base material to be welded. While the chuck 10 is chucked, the other lower end portion of the tubular welding base material is supported as the welding base material support roller 18 so that the tubular welding base material 20 is horizontally mounted on the inner surface welding apparatus of the tubular welding base material 20 of the present invention. .

그 뒤, 용접기홀더(17)를 용접홀더이송대(16)의 용접홀더고정구(15)에 고정시키고 이 용접기홀더(17)에 코일로된 용접봉을 장착하여 용접봉이 튜브형태로 형성된 튜브형 용접모재의 용접할 면에 근접하게 위치시키며, 용접모재지지롤러(18)의 외측 소정위치에 설치된 예열토치(19)를 점화시켜서 용접할 튜브형 용접모재의 외주면으로 화염을 분사시킨다.Thereafter, the welding machine holder 17 is fixed to the welding holder fixing tool 15 of the welding holder carrier 16, and the welding machine holder is equipped with a coiled welding rod to weld the tubular welding base material in which the welding rod is formed in the form of a tube. Located near the surface, the preheating torch 19 installed at a predetermined position outside of the welding base material support roller 18 is ignited to inject flames to the outer circumferential surface of the tubular welding base material to be welded.

이렇게 튜브형 용접모재를 장착하고 용접기홀더(17)를 장착하며 예열토치(19)에서 화염이 분사되면 구동모터(3)와, 코일로된 용접봉(21)을 연속하여 공급하는 용접봉 공급장치(미도시) 그리고 용접기(미도시)를 각각 구동시킨다.A welding rod supply device (not shown) for mounting a tubular welding base material, mounting a welder holder 17, and continuously supplying a driving motor 3 and a coiled welding rod 21 when a flame is injected from the preheating torch 19. ) And each welder (not shown) is driven.

상기와 같이 구동모터(3)가 구동되면 구동모터(3)의 회전력이 구동모터(3)의 모터풀리(2)를 통하여 1차풀리(6)와 2차풀리(7) 그리고 스크류회전축(13)의 회전풀리(11)를 각각 회전시키게 되는데, 모터풀리(2)로 부터 공급된 회전력이 이단으로 구성된 1차풀리(6)와 2차풀리(7)을 통하면서 회전력이 감소되어 감속된 회전력으로 각각의 회전축(4)(9)(13)을 회전시키게 된다.As described above, when the driving motor 3 is driven, the rotational force of the driving motor 3 passes through the primary pulley 6, the secondary pulley 7, and the screw rotation shaft 13 through the motor pulley 2 of the driving motor 3. Rotating pulley 11 of the rotation) is rotated, respectively, the rotational force supplied from the motor pulley 2 through the primary pulley 6 and the secondary pulley (7) consisting of two-stage rotational force is reduced to reduce the rotational force Each of the rotating shafts 4, 9, 13 is rotated.

상기와 같이 각각의 회전축이 감속 회전함에 따라 척(10)에 척킹된 튜브형 용접모재도 척(10)과 동일하게 회전하는데, 튜브형 용접모재의 하단부에는 튜브형 용접모재의 하단부를 회전 지지하는 용접모재지지롤러(18)가 설치되어서 척(10)에 척킹된 튜브형 용접모재가 안정되게 수평상태에서 회전을 하게 된다.As described above, as each rotary shaft rotates at a reduced speed, the tubular welding base material chucked to the chuck 10 also rotates in the same manner as the chuck 10. The lower end of the tubular welding base is welded to support the lower end of the tubular welding base material. The roller 18 is installed so that the tubular welding base material chucked to the chuck 10 rotates in a stable horizontal state.

그리고, 스크류회전축(13)도 2차풀리(7)로부터 동력을 전달받아 회전하고 있으며 일측 단부에 스크류(12)가 형성되어 있고, 이 스크류(12)에는 용접홀더이송대(16)의 브라켓트(14)가 나사식으로 외삽되어 있어서 스크류(12)에 외삽된 브라켓트(14)가 도 2의 "A"와 같이 수평으로 이동하게 된다.The screw rotation shaft 13 is also rotated by receiving power from the secondary pulley 7, and a screw 12 is formed at one end thereof, and the screw 12 has a bracket 14 of the welding holder feeder 16. ) Is extrapolated in a screw type so that the bracket 14 extrapolated to the screw 12 is moved horizontally as shown by " A "

이와 같이 구동모터(3)의 회전력에 의해 튜브형 용접모재가 회전하고 있고 브라켓트(14)는 직선방향으로 수평 이동하는 상황에서 용접기(미도시)에서 전원이 공급되게 되면, 전도체인 튜브형 용접모재(20)와 용접봉(21)의 사이에서 아크가 발생하면서 용접작업이 이루어 진다.Thus, when the tubular welding base material is rotated by the rotational force of the driving motor 3 and the bracket 14 is horizontally moved in the linear direction, power is supplied from the welding machine (not shown), and the tubular welding base material 20 is a conductor. ) And the welding operation is made while the arc is generated between the electrode (21).

상기와 같이 용접이 이루어지고 있는 상황에서도 위에서 설명한 바와 같이 튜브형 용접모재가 회전하고 있고 용접기홀더(17)는 수평으로 이동하고 있기 때문에 튜브형 용접모재의 내주연에는 균일하고 안정된 비드가 형성되면서 튜브형 용접모재의 내주연에 연속적으로 용접을 할 수 있게 되는 것이다.As described above, even when the welding is performed as described above, since the tubular welding base material is rotating and the welder holder 17 is moving horizontally, a uniform and stable bead is formed on the inner circumference of the tubular welding base material while the tubular welding base material is formed. It will be able to continuously weld on the inner periphery of.

그리고, 상기와 같이 용접이 이루어지는 과정에서 튜브형 용접모재의 외주연에는 예열토치(19)에서 화염이 연속적으로 분사되고 있어서 용접하고자 하는 튜브형 용접모재를 예열시키기되어 용접속도를 증속시킬 수 있어 생산성을 향상시킬 수 있게 되는 것이다.Further, in the process of welding as described above, flames are continuously injected from the preheating torch 19 at the outer periphery of the tubular welding base material, thereby preheating the tubular welding base material to be welded to increase the welding speed, thereby improving productivity. You will be able to.

상기와 같이 본 발명의 튜브형 용접모재의 내면용접장치는, 튜브형태로 형성된 튜브형 용접모재를 척으로서 척킹한 뒤에 척을 회전시켜 튜브형 용접모재가 일정한 속도로 회전하게 하고, 코일로된 용접봉이 연속적으로 공급되는 용접기홀더는 상기 척과 연동되어 일정한 속도로 수평이동할 수 있도록 함으로서, 튜브형태로 형성된 튜브형 용접모재의 내주연에 연속적으로 안정되게 용접을 할 수 있어서 용접불량이 발생할 염려가 전혀없는 장점과, 생산성이 향상되는 장점과, 인력에 의존하지 않고 자동적으로 용접이 이루어져 인체가 손상될 염려가 없는 등의 효과를 지닌 매우 특출한 효과가 있는 것이다.As described above, the inner surface welding device of the tubular welding base material of the present invention, after chucking the tubular welding base material formed in the form of a tube as a chuck to rotate the chuck so that the tubular welding base material rotates at a constant speed, the coiled welding rod continuously The welder holder supplied can be horizontally moved at a constant speed in conjunction with the chuck, so that welding can be continuously and stably welded on the inner circumference of the tubular welding base material formed in the form of a tube, and there is no fear of welding defects. There is a very special effect of this improved advantage, and the effect of such that there is no risk of damaging the human body by automatically welding without depending on the manpower.
