Description

파형부재 자동 용접장치의 설치상태 측정구{Implement for measuring set state of corrugated member automatic welder}{Installation for measuring set state of corrugated member automatic welder}

본 고안은 파형부재의 자동 용접에 관한 것으로, 더욱 상세하게는 파형부재 자동 용접장치의 초기설치시 직각도 및 평행도 등의 설치상태를 용이하게 측정할 수 있는 전용의 측정구에 관한 것이다.The present invention relates to the automatic welding of the corrugated member, and more particularly to a dedicated measuring tool that can easily measure the installation state, such as the squareness and parallelism during the initial installation of the corrugated member automatic welding device.

종래 기술에 따른 파형부재 자동 용접장치는 파형곡면이 존재하는 피용접물의 상측에 설치된 안내부를 따라 주행하여 용접토치부를 종행시키는 종구동부와, 이 종구동부에 일체로 설치되어 용접토치부를 횡행시키는 횡구동부와, 이 횡구동부에 일체로 설치되어 용접토치부를 상행 또는 하행시키는 상하구동부와, 용접토치부에 정속으로 와이어를 송급하는 와이어송급부와, 피용접물과의 거리 변화를 감지하여 파형곡면의 형상을 감지하는 프로브센서부로 구성된다.Corrugated member automatic welding device according to the prior art is a longitudinal drive unit for driving the welding torch part by running along the guide portion provided on the upper side of the to-be-welded object having a corrugated curved surface, and a transverse driving part which is integrally installed on the longitudinal driving part and traverses the welding torch part. And an up-and-down drive unit which is integrally installed in the lateral drive unit to raise or lower the welding torch unit, a wire supply unit which feeds the wire at a constant speed to the welding torch unit, and detects a change in the distance of the corrugated curved surface by detecting a change in distance between the welded object. It consists of a probe sensor to detect.

이와 같이 구성된 종래의 파형부재 자동 용접장치는, 용접 중 나타나는 파형곡면의 형상이 프로브센서부에 의해 감지되며, 이 감지신호에 의거하여 파형곡면의 형상을 인식하는 제어부에 의해 상하구동부가 제어되어 용접토치부에 의해 용접이 수행된다.In the conventional corrugated member automatic welding device configured as described above, the shape of the curved surface appearing during welding is detected by the probe sensor unit, and the upper and lower driving parts are controlled by the control unit that recognizes the shape of the curved surface based on the detection signal. Welding is performed by the torch part.

용접선의 변화는 통상 작업자가 육안으로 판별하며, 용접선의 벗어난 정도에 따라 횡구동부를 수동 조작하여 용접토치부의 위치를 조절한다.The change of the welding line is usually visually determined by the operator, and the position of the welding torch is adjusted by manually manipulating the lateral drive unit according to the deviation of the welding line.

한편, 이러한 용접장치는 종구동부가 안내부에 주행 가능하게 설치되며, 여타의 구성은 종구동부에 일체로 설치되어 있으므로 자중에 의해 앞쪽으로 약간 기울게 된다.On the other hand, such a welding device is installed so that the longitudinal drive portion is capable of traveling in the guide portion, the other configuration is installed in the longitudinal drive portion integrally inclined slightly forward by its own weight.

따라서, 초기설치시에는 직각자나 다이얼게이지 등을 이용하여 직각도 및 평행도를 측정한 후 측정값에 따라 그 설치상태를 보정한다.Therefore, at the time of initial installation, the squareness and the parallelism are measured using a square ruler or dial gauge, and then the installation state is corrected according to the measured value.

전술한 바와 같은 종래 기술에 의하면 용접선이 직선 구간일 경우에는 자동 용접에 따른 제반 문제가 발생되지 않으나 파형곡면 구간의 경우에는 반드시 작업자에 의한 수동 조작이 보조되어야 하는 번거로움이 있다.According to the prior art as described above, when the welding line is a straight section, there are no problems caused by automatic welding, but in the case of a corrugated curved section, manual operation by an operator must be assisted.

그리고, 파형곡면 구간에서는 작업자의 판단에 따라 용접토치부의 위치가 조절되므로 숙련도에 의해 용접품질이 좌우된다.And, since the position of the welding torch is adjusted according to the operator's judgment in the corrugated curved section, the welding quality depends on the skill level.

특히, 장치의 초기설치시 그 설치상태를 측정함에 있어서 전용의 측정구를 사용하지 않고 직각자나 다이얼게이지 등을 이용하였으므로 정확한 측정 및 설치가 어려운 문제점이 있었다.In particular, in the initial installation of the device, because it uses a right angle or dial gauge without using a dedicated measuring tool in the installation state, there was a problem that accurate measurement and installation is difficult.

따라서, 본 고안은 상기와 같은 종래 기술의 문제점을 해결하고자 제안한 것으로서, 파형부재 자동 용접장치의 초기설치시 직각도 및 평행도 등의 설치상태를 용이하게 측정할 수 있는 전용의 측정구를 제공하는 데 그 목적이 있다.Therefore, the present invention is proposed to solve the problems of the prior art as described above, to provide a dedicated measuring sphere that can easily measure the installation state, such as the perpendicularity and parallelism during the initial installation of the corrugated member automatic welding device The purpose is.

본 고안의 실시예로는 다수개가 존재할 수 있으며, 이하에서는 첨부한 도면을 참조하여 바람직한 실시예에 대하여 상세히 설명하기로 한다. 이 실시예를 통해 본 고안의 목적, 특징 및 이점들을 보다 잘 이해할 수 있게 된다.There may be a plurality of embodiments of the present invention. Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings. Through this embodiment, it is possible to better understand the objects, features and advantages of the present invention.

도 1은 본 고안에 따른 설치상태 측정구가 적용되는 파형부재 자동 용접장치의 구성도이다.1 is a block diagram of a corrugated member automatic welding device to which the installation state measuring sphere according to the present invention is applied.

이에 나타낸 파형부재 자동 용접장치는, 파형곡면이 존재하는 피용접물의 상측에 설치된 안내부(1)를 따라 주행하여 피용접물을 용접하기 위한 용접토치부(2)를 종행시키는 종구동부(3)와, 이 종구동부(3)와 일체로 되어 용접선을 따라 용접토치부(2)를 횡행시켜 그 위치가 용접선에 대응하여 자동 조절되게 하는 횡구동부(4)와, 이 횡구동부(4)를 통해 종구동부(3)와 일체로 되어 상기 감지된 형상에 따라 용접토치부(2)를 상행 또는 하행시키는 상하구동부(5)와, 이 상하구동부(5)와 일체로 되어 상기 감지된 형상에 따라 용접토치부(2)를 회전시키는 회전구동부(6)와, 피용접물과의 거리 변화를 감지하여 파형곡면의 형상을 감지하는 프로브센서부(7)와, 이 회전구동부(6)와 일체로 되어 상기 감지된 형상에 따라 회전하며 피용접물에 레이저를 주사한 후 레이저 반사광을 통해 파형곡면의 표면 영상을 취득하는 레이저센서부(8)와, 용접토치부(2)에 정속으로 와이어를 송급하는 와이어송급부(9)와, 프로브센서부(7) 및 레이저센서부(8)의 감지값에 따라 전체 시스템을 제어하는 제어부(도시 생략됨)로 구성된다.The corrugated member automatic welding device shown here includes a longitudinal driving part 3 which runs along a guide part 1 provided on the upper side of the welded object having a corrugated curved surface and terminates the welding torch unit 2 for welding the welded object. And a transverse driving portion 4 which is integral with the longitudinal driving portion 3 and traverses the welding torch portion 2 along the welding line so that its position is automatically adjusted in response to the welding line, and through the transverse driving portion 4. An up-and-down driving part 5 which is integral with the eastern part 3 and moves up or down the welding torch part 2 according to the detected shape, and is welded according to the detected shape by being integrated with the up-and-down driving part 5. The rotary drive unit 6 for rotating the teeth 2, the probe sensor unit 7 for detecting the shape of the curved surface by detecting the change of the distance between the object to be welded, and the rotary drive unit 6 is integrated with the detection Rotates according to the shape, and after scanning the laser on the object A laser sensor unit 8 for acquiring the surface image of the curved surface through the reflected light, a wire supply unit 9 for feeding wires to the welding torch unit 2 at a constant speed, a probe sensor unit 7, and a laser sensor unit A control unit (not shown) for controlling the entire system in accordance with the detected value of (8).

이와 같이 구성된 파형부재 자동 용접장치는, 용접 진행 중에 프로브센서부(7)가 피용접물과의 거리 변화를 감지하여 파형곡면의 형상을 감지하며, 이 감지신호에 의거하여 제어부(도시 생략됨)는 파형곡면의 형상을 인식한다.Corrugated member automatic welding device configured as described above, the probe sensor unit 7 detects the change of the distance to the object to be welded during the welding process to detect the shape of the curved surface, the control unit (not shown) based on this detection signal is Recognize the shape of the waveform.

제어부에 의해 회전구동부(6)가 제어되어 용접토치부(2) 및 레이저센서부(8)가 파형곡면의 형상에 따라 회전되며, 레이저센서부(8)는 피용접물의 파형곡면에 레이저를 주사한 후 피용접물에서 반사되는 레이저 반사광을 통해 파형곡면의 표면 영상을 취득한다.The rotary drive unit 6 is controlled by the control unit so that the welding torch unit 2 and the laser sensor unit 8 are rotated according to the shape of the corrugated curved surface, and the laser sensor unit 8 scans the laser on the corrugated curved surface of the welded object. After that, the surface image of the curved surface is acquired through the laser reflected light reflected from the welded object.

여기서, 제어부는 레이저센서부(8)를 통해 취득된 피용접물의 표면 영상을 분석하여 피용접물의 용접선을 인식한다. 즉 피용접물의 표면으로 주사된 레이저 띠는 피용접물의 상판과 하판이 겹치는 부분에서 굴곡이 발생되며, 제어부는 취득된 표면 영상에서 곡부를 감지하여 용접선을 인식한다.Here, the controller analyzes the surface image of the welded object obtained through the laser sensor unit 8 to recognize the weld line of the welded object. That is, the laser band scanned on the surface of the welded object is bent at the overlapping portion of the upper and lower plates of the welded object, and the controller recognizes the weld line by sensing the curved portion in the acquired surface image.

이후, 용접선을 인식한 제어부는 현재 용접토치부(2)의 위치가 용접선에서 벗어난 정도를 계산한 후 횡구동부(4)를 제어하여 용접토치부(2)의 위치를 정밀 조절하며, 상기와 같이 제어부는 프로브센서부(7) 및 레이저센서부(8)의 감지값에 따라 종구동부(3)와, 횡구동부(4), 상하구동부(5), 회전구동부(6), 와이어송급부(9), 및 용접토치부(2)를 제어하여 자동 용접을 수행한다.Subsequently, the control unit recognizing the welding line calculates the degree to which the position of the current welding torch unit 2 deviates from the welding line, and then controls the horizontal drive unit 4 to precisely adjust the position of the welding torch unit 2, as described above. The control unit according to the detection values of the probe sensor unit 7 and the laser sensor unit 8, the longitudinal drive unit 3, the lateral drive unit 4, the vertical drive unit 5, the rotary drive unit 6, the wire feed unit 9 ), And the welding torch unit 2 is controlled to perform automatic welding.

한편, 상기와 같은 자동 용접장치는 종구동부(3)가 안내부(2)에 주행 가능하게 설치되며, 여타의 구성은 종구동부(3)에 일체로 설치되어 있으므로 종래 기술 설명에서도 언급한 바와 같이 초기설치시 자중에 의해 앞쪽으로 약간 기울게 되므로 이를 보정하여야 한다.On the other hand, in the automatic welding device as described above, since the longitudinal drive unit 3 is installed to run on the guide unit 2, and the other configuration is integrally installed on the longitudinal drive unit 3, as mentioned in the prior art description. This should be calibrated forward due to its own weight due to its initial installation.

특히, 회전구동부(6)에 의해 레이저센서부(8)가 파형곡면을 따라 회전되고, 회전 운동 중에 레이저센서부(8)에 의해 취득된 영상으로부터 용접선이 인식되므로 레이저센서부(8)의 회전축이 정확하게 세팅되어야 한다. 즉 레이저센서부(8)의 회전축이 종구동부(3)의 주행축에 직각을 이루어야만 정확한 용접선 추적 및 양호한 용접품질을 기대할 수 있다.In particular, the rotary sensor 6 rotates the laser sensor unit 8 along the curved surface, and the welding line is recognized from the image acquired by the laser sensor unit 8 during the rotary motion, so that the rotary shaft of the laser sensor unit 8 is rotated. Should be set correctly. In other words, the axis of rotation of the laser sensor unit 8 must be perpendicular to the axis of travel of the longitudinal drive unit 3 so that accurate weld line tracking and good welding quality can be expected.

따라서, 자동 용접장치의 설치상태를 측정한 후에 그 측정결과에 따라 설치상태를 보정하거나 재설치하여야 하며, 본 고안에서는 이를 위해 전용의 측정구를 제공한다.Therefore, after measuring the installation state of the automatic welding device, the installation state should be corrected or reinstalled according to the measurement result, and the present invention provides a dedicated measuring tool for this purpose.

도 2는 도 1에 도시된 자동 용접장치의 설치상태 측정구 설치부위의 상세도이며, 도 3은 도 2의 정면도이고, 도 4는 본 고안에 따른 설치상태 측정구의 사시도이다.Figure 2 is a detailed view of the installation state measurement sphere installation site of the automatic welding device shown in Figure 1, Figure 3 is a front view of Figure 2, Figure 4 is a perspective view of the installation state measurement sphere according to the present invention.

본 고안에 따른 설치상태 측정구(100)는, 종구동부(3)의 주행축에 직교하게 설치 가능한 수직지그(101)와, 이 수직지그(101)에 직교하게 일체를 이루며 피용접물 상면에 수평하게 안착 가능한 수평지그(102)로 구성되며, 수평지그(102)의 상면에는 상기 수평 안착시 그 중심선이 종구동부(3)의 주행축에 직교하며 피용접물의 수평축에 평행하는 오목곡면(102a)이 형성되어져 있다.The installation state measuring instrument 100 according to the present invention is a vertical jig 101 that can be installed orthogonal to the traveling shaft of the longitudinal drive unit 3, and is integrally orthogonal to the vertical jig 101 and horizontal to the surface to be welded. It is composed of a horizontal jig 102 that can be seated, and the upper surface of the horizontal jig 102, the center line of the horizontal jig when the horizontal mounting is perpendicular to the running axis of the longitudinal drive portion 3 and a concave curved surface 102a parallel to the horizontal axis of the welded object Is formed.

수직지그(101)는 안내부(1)에 고정되는 고정지그(103)에 일체로 결합되어 종구동부(3)의 주행축에 직교하도록 설치된다.The vertical jig 101 is integrally coupled to the fixing jig 103 fixed to the guide part 1 and installed to be perpendicular to the travel shaft of the longitudinal drive part 3.

이와 같이 구성된 측정구(100)는, 수직지그(101)가 고정지그(103)에 결합된 상태에서 종구동부(3)의 주행축에 직교하므로 수평지그(102)의 상면에 형성된 오목곡면(102a)은 자동으로 종구동부(3)의 주행축에 직교하며 피용접물의 수평축에 평행하게 배치된다.The measuring sphere 100 configured as described above is a concave curved surface 102a formed on the upper surface of the horizontal jig 102 because the vertical jig 101 is orthogonal to the traveling axis of the longitudinal drive unit 3 in a state where the vertical jig 101 is coupled to the fixed jig 103. ) Is automatically orthogonal to the traveling axis of the longitudinal drive part 3 and arranged parallel to the horizontal axis of the welded object.

이러한 상태에서 작업자는 측정구(100)를 기준으로 하여 자동 용접장치의 직각도 및 평행도를 측정하며, 그 측정결과에 따라 자중에 의한 기울어짐 등을 보정한다.In this state, the operator measures the orthogonality and parallelism of the automatic welding apparatus based on the measuring tool 100, and corrects the inclination due to its own weight according to the measurement result.

아울러, 레이저센서부(8)의 설치상태를 확인하기 위해서는 회전구동부(6) 및 레이저센서부(8)를 시험 가동한다.In addition, in order to confirm the installation state of the laser sensor unit 8, the rotary drive unit 6 and the laser sensor unit 8 are tested.

그러면, 레이저센서부(8)에 의하여 수평지그(102)의 오목곡면(102a)에는 레이저가 주사되며, 작업자는 오목곡면(102a)에 형성되는 레이저 띠의 범위를 확인하여 레이저센서부(8)의 회전축이 종구동부(3)의 주행축에 직각을 이루는지를 판단한다.Then, the laser is scanned on the concave curved surface 102a of the horizontal jig 102 by the laser sensor unit 8, and the operator checks the range of the laser band formed on the concave curved surface 102a and the laser sensor unit 8. It is determined whether the rotating shaft of the orthogonal axis is perpendicular to the traveling shaft of the longitudinal drive unit 3.

여기서, 레이저센서부(8)에 의해 형성되는 레이저 띠가 오목곡면(102a)을 벗어나거나 그 중앙을 벗어나면 레이저센서부(8)의 회전축이 종구동부(3)의 주행축과 직각을 이루지 않는 경우이다. 이에 레이저 띠가 오목곡면(102a)을 벗어나지 않고 그 중앙에 위치하도록 레이저센서부(8)의 설치상태를 보정하면 레이저센서부(8)의 회전축과 종구동부(3)의 주행축이 직각을 이루어 정확한 용접선 추적 및 양호한 용접품질이 제공된다.Here, when the laser band formed by the laser sensor unit 8 is outside the concave curved surface 102a or out of the center thereof, the rotation axis of the laser sensor unit 8 does not form a right angle with the traveling axis of the longitudinal drive unit 3. If it is. Accordingly, when the installation state of the laser sensor unit 8 is corrected so that the laser strip is positioned at the center thereof without departing from the concave curved surface 102a, the rotation axis of the laser sensor unit 8 and the traveling axis of the longitudinal drive unit 3 are perpendicular to each other. Accurate weld line tracking and good weld quality are provided.

상술한 바와 같이 본 고안은, 전용의 설치상태 측정구를 제공하여 자동 용접장치의 초기설치시 직각도 및 평행도 등을 용이하게 측정할 수 있을 뿐만 아니라 파형곡면을 따라 회전하는 레이저센서부의 회전축을 정확하게 세팅할 수 있다.As described above, the present invention provides a dedicated installation state measuring tool, which enables easy measurement of squareness and parallelism during initial installation of the automatic welding device, as well as accurate rotation axis of the laser sensor unit rotating along the curved surface. You can set it.

따라서, 설치작업의 능률이 향상되면서도 높은 용접품질을 지속적으로 제공할 수 있는 효과가 있다.Therefore, there is an effect that can continuously provide high welding quality while improving the efficiency of installation work.
