본 발명은 파이프와 파이프 또는 파이프단부에 플랜지, T관, L관 등 배관부속물 등을 자동으로 용접하는 파이프 자동 용접장치에 관한 것으로 특히, 용접하고자 하는 파이프를 일정속도로 회전시키면서, 파이프 외주의 용접선을 따라 자동으로 용접하여 좌,우 파이프를 길이방향으로 용접하거나 파이프단부에 배관부속물 등을 자동으로 용접하는 파이프 자동 용접장치에 관한 것이다.The present invention relates to a pipe automatic welding device for automatically welding pipes and pipe fittings such as flanges, T pipes, L pipes, etc. to the pipe end, and in particular, while welding the pipe to be welded at a constant speed, The present invention relates to a pipe automatic welding device for automatically welding left and right pipes along the lengthwise direction or automatically welding pipe fittings to pipe ends.

용접이라 하면 철판과 철판을 맞대고 맞댄면을 서로 녹여 부착하는 것으로 철판의 종류와 두께에 따라 다양한 용접방법이 사용되고 있다.Welding is to attach iron plate and iron plate to each other by melting the butt face together, and various welding methods are used according to the type and thickness of iron plate.

또한 용접 방법에 따라 용접선을 따라 용접기가 자동으로 이동하면서 용접하는 자동용접과, 용접선을 따라 사람이 일일이 수동으로 용접하는 수동용접으로 구분 할 수 있다.In addition, according to the welding method can be divided into automatic welding welding while moving the welding machine automatically along the welding line, manual welding that the person manually welds along the welding line.

자동용접은 용접선이 직선형태나 용접하고자 하는 모재가 평판인 경우 자동용접을 수행하는 것을 볼 수 있다.Automatic welding can be seen to perform the automatic welding when the welding line is a straight form or the base material to be welded is a flat plate.

자동용접은 수동용접에 비해 용접품질이 우수하며, 용접시간이 단축되는 효과를 가져 용접 생산성이 우수한 것을 볼 수 있다.Automatic welding has better welding quality than manual welding, and it can be seen that welding productivity is excellent due to the shortening of welding time.

이에 반해 수동용접은 자동용접과 같이 높은 생산성을 갖지는 못하지만, 자동용접할 수 없는 부위나 위치에서는 사람이 일일이 수동으로 용접하게된다.On the other hand, manual welding does not have high productivity like automatic welding, but manual welding is performed manually at a part or location where automatic welding cannot be performed.

앞에서 언급한 바와 같이 평판상의 철판이나, 용접부위가 일정한 형태를 갖는것에 있어서는 전용 자동용접장치를 사용되고 있으나, 파이프와 파이프를 길이방향으로 맞접합하는 원통형 용접물에 대해서는 자동용접장치가 개발되지 못해 일일이 사람이 수동으로 용접하는 바 이를 해결하고자 본 발명이 개발된 것이다.As mentioned above, a dedicated automatic welding device is used for flat plates or welded parts. However, the automatic welding device cannot be developed for cylindrical welds in which the pipe is welded in the longitudinal direction. The present invention was developed to solve this manual welding.

It can be seen that it consists of a nozzle and other accessories.

본 발명은 금속재 파이프와 파이프 단부를 연이어 파이프를 길이 방향으로 연장하거나, 파이프 단부에 플랜지, T관, L관 등 파이프배관 부속물 등을 부착하거나, 파이프 단부에 덮개를 용접에 의해 부착하여 원통형 용기를 제작함에 있어, 원통형상의 외주를 자동용접에 의해 부착되도록 하여 고품질의 용접부를 얻으며, 용접시간을 단축할 수 있는 파이프 자동용접장치를 제공하는 것이다.The present invention extends the pipe in the longitudinal direction by connecting the metal pipe and the pipe end, or attaching pipe fittings such as flange, T pipe, L pipe to the pipe end, or by attaching a cover to the pipe end by welding to form a cylindrical container. In manufacturing, the outer periphery of the cylindrical shape is attached by automatic welding to obtain a high quality welded portion, and to provide a pipe automatic welding device that can shorten the welding time.

본 발명은 파이프와 같이 원통 형상의 외주면을 자동으로 용접하는 것으로, 용접물을 일측에 용접토치를 위치시키고, 용접물을 일정속도로 회전시키면서 원통 형 외주면에 용접하여 균일하면서도 빠르게 용접 됨과 동시에 균일한 용접면을 얻는 것을 목적으로 개발된 것 이다.The present invention automatically welds a cylindrical outer circumferential surface, such as a pipe, and places a weld torch on one side, and welds to the cylindrical outer circumferential surface while rotating the weld at a constant speed so that it is welded uniformly and quickly and at the same time a uniform weld surface It was developed for the purpose of getting

구동몸체(11)내측에 장착되는 동력발생부인 모터(12)및 감속기(13)에 의해 회전구(14)는 균일한 속도로 회전되며, 그 회전속도는 용접물의 두께나 직경에 따라임의로 조절 된다. 따라서, 용접물의 두께가 얇은 철판은 회전속도를 빠르게 조 절하며, 용접물의 두께가 두꺼운 철판은 회전속도는 속도를 늦게 조절하는 등 용접 파이프의 직경 및 두께에 따라 임의로 회전구(14)의 속도를 조절하며, 회전구(14)에는 선반에서 볼 수 있는 고정척(15)가 부착되어지며 이에 용접하고자 하는 용접물(100)을 고정하게 된다. 그 후 용접물(100)에 용접하고자 하는 피용접물(101)을 제1레일(22) 위의 용접물지지장치(31)에 올려놓은 후 용접물지지장치(31) 하부몸체(33)의 높이조절구(34)와, 상부몸체(35)의 좌우 2개의 구름바퀴(36) 간격을 조절하여 고정척(15)에 고정된 용접물(100)의 단부와 용접물 지지장치(31)위에 올려진 피용접물(101)의 단부를 일치시킨후, 용접물(100)과 피용접물(101)이 맞닿은 단면 즉 용접선 부위를 가용접(스폿용접)하여 용접물(100)과 피용접물(101)을 부착하고, 하부지지대(21)의 제2레일(23)위의 용접토치이동몸체(41)의 용접토치(52)를 용접선에 위치시킨후 용접기를 작동하여 용접물(100)과 피용접물(101)을 회전시키면서, 용접물(100)과 피용접물(101)의 용접선을 용접하게 되는 것이다.The rotary sphere 14 is rotated at a uniform speed by the motor 12 and the reducer 13, which are the power generating units mounted inside the drive body 11, and the rotational speed is arbitrarily adjusted according to the thickness or diameter of the weldment. . Therefore, the thin plate of the weld is to adjust the speed of rotation rapidly, the thick plate of the weld is to adjust the speed of the rotary ball 14 arbitrarily in accordance with the diameter and thickness of the weld pipe, such as the rotation speed is controlled to slow the speed. To adjust, the rotary ball 14 is attached to the fixed chuck 15 visible from the shelf is fixed to the weld 100 to be welded thereto. Thereafter, the welded object 101 to be welded to the weldment 100 is placed on the weldment support device 31 on the first rail 22, and then the height adjusting hole of the lower body 33 of the weldment support device 31 34 and the welded object 101 mounted on the end of the weldment 100 fixed to the fixed chuck 15 and the weldment support device 31 by adjusting the distance between the left and right two wheels 36 of the upper body 35.
