It is divided into welding zone (4), the inner surface of the left and right welding zone (3, 4) is welded with the front and rear welding zone (1, 2), and are combined with each other to form a rectangular space in the center, The upper surface of the front and rear welding table (1, 2) is provided with a plurality of ball rollers 5 protruding in part than the surface of the front and rear welding table (1, 2) and inserted freely rotated in the space, The upper part of the long groove 6, which has the stepped 6 'of the shape of "' " Insert the pedestal of the clamp 50 is fixed to the clamp 50 so that the clamp 50 does not move the specimen.

그리고, 상기 좌측 용접대(3)의 내측면 중앙에는 용접대(10)를 일측에서 회전시키는 회전축이 관통하면서 상기 지지주(20)와 연결되어 축 회전되게 설치된다. 우측 용접대(4)는 외측면 중앙에 내접기어가 구비되어 우측 지지주(20)의 외측에 설치된 기어박스(40)의 구동축 끝단 외접기어와 치차 결합되어 상기 기어박스(40)의 회전 구동축에 의해 용접대(10)가 회전되게 하고, 외측단면에는 우측 지지주의 양측에 설치된 전후진 스토퍼(21)에 대응하는 홈(21')이 양측에 형성되어 있어 상기 스토퍼(21)가 홈(21')에 돌출.삽입되면 용접대(10)의 회전이 고정된다.In addition, a rotation shaft for rotating the welding table 10 at one side is installed in the center of the inner side surface of the left welding table 3 to be axially rotated in connection with the support column 20. The right welding table 4 is provided with an internal gear at the center of the outer surface, and is geared with the external shaft gear of the drive shaft end of the gear box 40 installed outside the right support column 20 to the rotation drive shaft of the gear box 40. The welding table 10 is rotated, and grooves 21 'corresponding to the forward and backward stoppers 21 provided on both sides of the right support column are formed at both sides, and the stoppers 21 are grooves 21'. Protruding into.) Rotation of the welding table 10 is fixed.

또한, 지지주(20)는 "독립문"형 형상으로 양측에 설치되며, 우측 지지주(20)의 상부 중앙을 핸들(41)이 구비된 상기 기어박스(40)의 구동축이 관통하며 용접대(10)와 연결되고, 상면 양측에는 회전 스토퍼(22)가 설치되어 용접대(10)의 회전을 고정고정시킨다. 또한, 상기 전후진용 롤러(20')에도 스토퍼(23)가 설치되어 본 시험용 반전장치의 전후진을 고정시킨다. 상기 스토퍼(23)에는 정지핀(23')이 구비되어 스토퍼를 안치시킨다.In addition, the support column 20 is installed on both sides in the shape of an "independent door", the drive shaft of the gear box 40 is equipped with a handle 41 penetrates the upper center of the right support column 20 and the welding table ( 10), and the rotary stopper 22 is installed on both sides of the upper surface to fix and fix the rotation of the welding table 10. In addition, a stopper 23 is also provided on the forward and backward rollers 20 'to fix the forward and backward movements of the test reverse device. The stopper 23 is provided with a stop pin 23 'to settle the stopper.

이와 같이 구성된 본 발명에 의한 수평 용접 시험용 반전장치의 동작을 첨부한 도면 도 2 및 도 3에 의거 상세히 설명하면 다음과 같다.The operation of the inverting apparatus for a horizontal welding test according to the present invention configured as described above will be described in detail with reference to FIGS. 2 and 3 as follows.

먼저 임시 고정편이 용접.부착된 용접 시험용 시편을 용접대(10)위에 설치하고, 레일(30) 상의 반전장치를 자동용접기의 토치 아래로 이동 시킨 뒤, 롤러 고정용 스토퍼(23)로 상기 반전장치를 고정시키고, 상기 시편을 용접기의 용접선과 일치 시킨다. 이때 용접대 상부의 볼롤러(5)가 설치되어 있어 위치의 수정이 매우 용이하고 우측 지지주에 설치된 전후진 스토퍼(21)와 회전 스토퍼(22)는 용접대(10)를 수평 고정시킬 때마다 사용한다. 그리고, 시편이 용접선에 일치되면 장홈(6)에 삽입 지지된 클램프(50)로 단단히 결속시키고, 용접대(10)를 회전시켜 시편이 반전되게 한뒤 백킹제를 붙인후 다시 반전시켜 용접을 실시하고, 용접이 완료되면 다시 반전시켜 백킹제를 제거한 뒤 비드상태를 확인하며 시험을 완료한다. 이때, 반전시키는 구동력은 핸들(41)이 부착된 기어박스(40)에 의해 적은 힘으로 충분하므로 상기 핸들을 회전시켜 구동축 끝단의 외접기어가 우측 용접대(4)의 내접기어를 회전시키게 되므로 이에 결합된 회전용 용접대가 반전된다. 이후, 용접 시험이 완료되면 역순으로 실시한다.First, the welding test specimen with the temporary fixing piece welded and attached is installed on the welding table 10, and the inverting device on the rail 30 is moved below the torch of the automatic welding machine, and then the inverting device is mounted with a roller fixing stopper 23. And fix the specimen to the weld line of the welder. At this time, the ball roller 5 of the upper part of the welding table is installed so that the position can be easily modified and the forward and backward stopper 21 and the rotary stopper 22 installed on the right support column each time the welding table 10 is fixed horizontally. use. Then, if the test piece is matched with the welding line, it is firmly bound by the clamp 50 inserted into the long groove 6, the welding table 10 is rotated so that the test piece is inverted, the backing agent is attached, and then the welding is performed again. After completion of welding, invert again to remove the backing agent and check the bead condition. At this time, the driving force to be reversed is sufficient by a small force by the gearbox 40 to which the handle 41 is attached, so that the external gear at the end of the drive shaft rotates the internal gear of the right welding rod 4 by rotating the handle. The combined welding strip is reversed. Thereafter, when the welding test is completed, it is performed in the reverse order.

따라서,본 발명은 수평 자동 용접기에 의한 용접 결과를 시험하기 위한 시편을 수시로 반전시켜 그 결과를 시각적으로 확인하여야 하나 중량이 무겁고 고열 용접열이 잔재하여 반전하기위한 조작이 어렵고 위험하므로 이를 해결함과 동시에 본 발명의 장치는 회전용 핸들과 레일을 이용하여 부드럽게 취급이 됨으로써, 주변의 시험 장치 및 작업자의 시험 환경에도 장해가 되지 않도록 소음,진동 및 충격을 최소화하는 정밀한 수평용접 시험용 반전장치인 것이다.Therefore, the present invention should be inverted from time to time to test the welding results by the horizontal automatic welding machine, but the results should be visually confirmed, but the weight is heavy and the heat of the high temperature welding heat remains difficult and dangerous to solve this problem and At the same time, the device of the present invention is a reversal device for precise horizontal welding test that minimizes noise, vibration, and impact so as to be smoothly handled by using a rotating handle and a rail so as not to interfere with the surrounding test apparatus and the operator's test environment.

이상에서 본 발명의 바람직한 실시예를 설명하였으나, 본 발명은 다양한 변화와 변경 및 균등물을 사용할 수 있다. 본 발명은 상기 실시예를 적절히 변형하여 동일하게 응용할 수 있음이 명확하다. 따라서 상기 기재 내용은 하기 특허청구범위의 한계에 의해 정해지는 본 발명의 범위를 한정하는 것이 아니다.Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

이상에서 본 바와 같이, 본 발명에 의한 수평용접 시험용 반전장치는 용접대 위에서 수평 자동용접기로 용접된 시편을 극소수의 작업자가 신속/정확하고 쉽게 이동 또는 반전시켜 뒷면(이면)의 비드상태와 전면의 용접상태를 극히 용이하게 확인할 수 있어 작업능률이 향상됨은 물론 안전사고의 문제점을 해소시켜 생산성 향상에 크게 이바지 할 뿐만 아니라, 작업장내에서의 진동, 추락 등의 위험을 크게 감소시켜 다른 작업자의 시험 환경에도 장애를 해소시키는 효과가 있다.As described above, the horizontal welding test reversing apparatus according to the present invention is a bead of the back and back of the front (back) by a small number of workers quickly or accurately and easily move or reverse the specimen welded by the horizontal automatic welding on the welding table The welding condition can be checked very easily, which not only improves the work efficiency but also solves the problem of safety accidents and greatly contributes to the improvement of productivity, and greatly reduces the risk of vibration and fall in the workplace to test environment of other workers. Edo has the effect of resolving obstacles.
