And a lower guide groove 34 formed to be in parallel with the upper guide groove 32 and a stop guide groove 33 connecting the upper guide groove 32 and the lower guide groove 34. do.

즉, 상기 회전축(30)에 형성된 가이드홈(31)은 상측에서부터 상단가이드홈(32), 중단가이드홈(33), 하단가이드홈(34)이 순차적으로 서로 연통되도록 소정깊이를 구비하고 형성되어 있으며, 상기 상단가이드홈(32)과 하단가이드홈(34)은 서로의 위치가 90°의 각도를 구비하며, 서로 평행하도록 회전축(30)에 형성되어 있다.
That is, the guide groove 31 formed on the rotating shaft 30 is formed with a predetermined depth so that the upper guide groove 32, the stop guide groove 33, the lower guide groove 34 communicate with each other sequentially from the top side. The upper guide groove 32 and the lower guide groove 34 have an angle of 90 ° to each other, and are formed on the rotation shaft 30 to be parallel to each other.

상기에서와 같이, 본 발명은 회전축(30)의 가이드홈(31)내에 안내핀(22)의 끝단이 삽입되도록 되어 있어, 유압실린더(40)에 의한 회전축(30)의 상하이동시, 고정설치된 안내핀(22)을 중심으로 회전축의 가이드홈(31)이 이동되므로, 유압실린더(40)가 작동되면, 회전축(30)의 상단가이드홈(32)내에 안내핀(22)이 위치하게 될 경우, 회전축(30)은 회전없이 상승작동하게 되고, 상단가이드홈(32)과 하단가이드홈(34)을 연결하는 중단가이드홈(33)에 안내핀(22)이 위치하게 될 경우, 회전축은 회전하면서 상승하게 되며, 하단가이드홈(34)에 안내핀(22)이 위치하게 될 경우, 상기 회전축(30)은 상단가이드홈(32)내에 안내핀(22)이 위치할 때보다 90°회전된 상태에서 회전축(30)이 상승하게 된다.
As described above, in the present invention, the end of the guide pin 22 is inserted into the guide groove 31 of the rotating shaft 30, so that the shank at the same time as the hydraulic shaft 40, the fixed guide is installed Since the guide groove 31 of the rotating shaft is moved around the pin 22, when the hydraulic cylinder 40 is operated, when the guide pin 22 is positioned in the upper guide groove 32 of the rotating shaft 30, The rotary shaft 30 is operated without rotation, and when the guide pin 22 is positioned in the stop guide groove 33 connecting the upper guide groove 32 and the lower guide groove 34, the rotating shaft rotates while When the guide pin 22 is positioned in the lower guide groove 34, the rotary shaft 30 is rotated by 90 ° than when the guide pin 22 is positioned in the upper guide groove 32. In the rotating shaft 30 is raised.

상기 유압실린더(40)는 몸체(42)가 커버부(20)의 하단에 고정설치되고, 로드(41)가 커버부 내측에 위치하는 회전축(30)의 하단에 일체로 고정설치된다.
The hydraulic cylinder 40 is the body 42 is fixedly installed on the lower end of the cover portion 20, the rod 41 is fixedly installed on the lower end of the rotary shaft 30 is located inside the cover portion.

상기 연결아암(50)은 커버부(20) 외측으로 돌출된 회전축(30)의 상단에 일측단이 볼트고정되고, 타측단에 클램프(60)의 중간부가 시소작동이 가능하도록 힌지결합되며, 이와 같이 설치되는 연결아암은 회전축(30)에 직각을 구비하도록 설치되어 있다.
The connecting arm 50 is bolted to one end of the upper end of the rotating shaft 30 protruding outside the cover portion 20, the other end is hinged to enable the seesaw operation of the intermediate portion of the clamp 60, and The connecting arm installed together is provided to have a right angle to the rotating shaft (30).

상기 클램프(60)는 유압실린더(40)에 의해 작동되어 붐(200)의 수평판(210)을 눌러 수직판(220)과 수평판(210)을 밀착시키는 것으로, 연결아암(50)의 타측단에 회전가능하도록 중간부가 핀연결되는 보조암(61)과, 상기 보조암(61)의 양측단에 회전가능하도록 각각 핀연결되고 붐의 수평판(210)에 접촉되어 유압실린더의 압력을 수평판에 전달하는 지지암(62)을 포함한다.
The clamp 60 is operated by the hydraulic cylinder 40 to press the horizontal plate 210 of the boom 200 in close contact with the vertical plate 220 and the horizontal plate 210, the other of the connecting arm (50) An auxiliary arm 61 having an intermediate part pinned to be rotatable at the side end, and a pin connected to both sides of the auxiliary arm 61 so as to be rotatable, are contacted with the horizontal plate 210 of the boom to receive the pressure of the hydraulic cylinder. And a support arm 62 for transmitting to the plate.

상기와 같이 구성된 본 발명은 유압실린더(40)의 상승작동시, 클램프(60)가 붐의 수평판(210) 용접위치로부터 이탈되고, 유압실린더(40)의 하강작동시, 클램프가 붐(200)의 수평판 용접위치로 이동되어 수평판(210)의 상측을 클램프에 의해 눌러 수평판(210)과 수직판(220)을 밀착시키게 된다. According to the present invention configured as described above, the clamp 60 is separated from the welding position of the horizontal plate 210 of the boom during the ascending operation of the hydraulic cylinder 40, and the clamp is the boom 200 when the descending operation of the hydraulic cylinder 40 is performed. The horizontal plate 210 is moved to the welding position of the horizontal plate 210 by pressing the upper side of the horizontal plate 210 is in close contact with the horizontal plate 210 and the vertical plate 220.

즉, 유압실린더(40)의 상승작동시에는 클램프(60)와 연결된 연결아암(50)이 용접대상물인 붐(200)과 서로 평행한 상태를 구비하게 되므로, 용접위치로의 소재 유입이 용이하게 된다. 이때, 상기 안내핀(22)은 회전축의 하단가이드홈(34)의 끝단에 위치하게 된다. That is, in the ascending operation of the hydraulic cylinder 40, the connecting arm 50 connected to the clamp 60 has a state parallel to each other and the boom 200, which is a welding object, so that material is easily introduced into the welding position. do. At this time, the guide pin 22 is located at the end of the lower guide groove 34 of the rotating shaft.

또한, 붐의 수평판(210)과 수직판(220)을 용접하고자 할 경우, 유압실린더(40)를 하강작동시키면, 회전축(30)은 커버부(20)내로 하강하기 시작한다. 이때, 고정된 안내핀(22)은 하단가이드홈(34)내에 위치하게 된다. In addition, when the horizontal plate 210 and the vertical plate 220 of the boom is to be welded, when the hydraulic cylinder 40 is lowered, the rotating shaft 30 starts to descend into the cover 20. At this time, the fixed guide pin 22 is located in the lower guide groove (34).

회전축이 계속 하강하여 하단가이드홈(34)에서 중단가이드홈(33)내에 안내핀이 위치하기 시작하면, 상단가이드홈(32)과 하단가이드홈(34)을 연결하는 중단가이드홈(33)에 의해 회전축(30)은 회전하게 되며, 중단가이드홈(33)에서 상단가이드홈(32)으로 안내핀(22)이 위치하게 되며, 회전축(30)의 회전은 중단되고 하강작동만이 이루어진다. 이때, 상기 연결아암(50)은 용접대상물인 붐(200)에 대하여 수직상태를 구비하게 되며, 하강되는 회전축(30)에 의해 연결아암(50) 및 클램프(60)가 하강되어 클램프(60)의 하단이 붐의 수평판(210) 상단에 접촉되므로, 클램프(60)의 중량 및 유압실린더(40)의 힘에 의해 수평판(210)과 수직판(220)을 밀착시키게 된다.
When the rotating shaft continues to descend and the guide pin is positioned in the stop guide groove 33 in the lower guide groove 34, the stop guide groove 33 connecting the upper guide groove 32 and the lower guide groove 34. The rotating shaft 30 is rotated, the guide pin 22 is positioned from the stop guide groove 33 to the upper guide groove 32, the rotation of the rotating shaft 30 is stopped and only the lowering operation is made. At this time, the connecting arm 50 has a vertical state with respect to the boom 200, which is a welding object, and the connecting arm 50 and the clamp 60 are lowered by the rotating shaft 30 that is lowered to clamp 60. Since the bottom of the contact with the top of the horizontal plate 210 of the boom, the horizontal plate 210 and the vertical plate 220 by the weight of the clamp 60 and the force of the hydraulic cylinder 40 is in close contact.

또한, 상기와 같이 구성 및 작동되는 본 발명은 붐 용접뿐 만 아니라, 건설장비의 아암 용접시에도 적용할 수 있다.
In addition, the present invention configured and operated as described above can be applied not only to boom welding, but also to arm welding of construction equipment.

본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위내에 있게 된다.
The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
