For example, data can be stored in the strain storage device 40 through communication using an RS 232 port, and displayed in real time simultaneously with the measurement. As the deformation storage device 40, for example, a personal computer, a notebook computer, or the like is used.

이하, 본 발명에 따른 변형량 측정장치의 작동에 대해 상세히 설명한다.Hereinafter, the operation of the strain measuring device according to the present invention will be described in detail.

먼저, 휨 또는 처짐이 발생된 시편이나 주 판재의 측정면 위에 프레임(10)을 설치한다. 즉, 레일(11)과 가로대(12)를 펼쳐 놓고, 각 가로대(12)의 힌지(13)를 움직이지 않도록 고정하여 대략 사각형의 프레임(10)을 형성한 후, 각 레일(11)의 양끝부분에 있는 높이조절나사(15)를 조절하여 프레임(10)이 어느 한쪽으로 기울거나 요동하지 않게 자세를 잡는다. First, the frame 10 is installed on the measurement surface of the test piece or the main plate material that warpage or deflection occurred. That is, the rails 11 and the crosspieces 12 are spread out, and the hinges 13 of the crosspieces 12 are fixed so as not to move to form a substantially rectangular frame 10, and then both ends of each rail 11 are formed. Adjust the height adjustment screw 15 in the part to position the frame 10 does not tilt or swing to either side.

이어서, 프레임(10)을 가로질러 레일(11) 위에 횡단부재(20)가 이동할 수 있게 올려놓은 다음, 다수의 롤러(31)와 모터(32) 및 레이저 센서(33)를 갖춘 주행대차(30)를 횡단부재(20) 위에 장착한다. 이때, 모터(32)는 제어장치(34)에 연결하고, 레이저 센서(33)는 변형량 저장장치(40)에 예컨대 RS 232 포트를 매개로 접속하고 나서, 전원을 인가한다. Subsequently, the transverse member 20 is placed on the rail 11 across the frame 10 so as to be movable, and then the traveling cart 30 having a plurality of rollers 31, a motor 32, and a laser sensor 33. ) Is mounted on the cross member 20. At this time, the motor 32 is connected to the control device 34, the laser sensor 33 is connected to the strain storage device 40, for example via the RS 232 port, and then applies power.

설치가 완료된 후, 측정자는 횡단부재(20)를 한쪽 가로대(12)에서부터 반대쪽 가로대(12)를 향해 소정 거리(레일(11)에 표시된 눈금)만큼 수동으로 이동시키고 조임나사(도시되지 않음)를 매개로 그 위치를 고정한 다음, 제어장치(34)를 조정하여 주행대차(30)를 이동시키면서 레이저 센서(33)를 통해 측정면의 변형량을 실시간으로 조사하게 된다. 주행대차(30)의 이동 및 레이저 센서(33)의 측정과 동시에 변형량 저장장치(40)는 실시간으로 데이터를 저장하고 그 결과를 그래프 또는 수치로 디스플레이하게 된다. After the installation is completed, the measurer manually moves the cross member 20 from one crossbar 12 to the opposite crossbar 12 by a predetermined distance (a scale marked on the rail 11) and tightens the tightening screw (not shown). After fixing the position by the medium, while adjusting the control device 34 to move the running cart 30 is irradiated in real time the amount of deformation of the measurement surface through the laser sensor 33. Simultaneously with the movement of the travel truck 30 and the measurement of the laser sensor 33, the deformation amount storage device 40 stores data in real time and displays the result as a graph or numerical value.

따라서, 본 발명은 주행대차에 부착된 레이저센서에 의해 측정자가 힘들이지 않고 용접변형에 의한 주 판재의 변형량을 정확히 측정할 수 있게 되는 것이다. 특히, 보강재가 용접된 주 판재의 이면에서 2차원 평면을 대상으로 변형량을 측정하되, 제어장치를 통해 주행대차가 일정한 속도로 주행하여 측정하고, 더구나 실시간으로 데이터를 저장하고 디스플레이할 수 있으며, 전체 장치의 경량화로 각 측정구 간으로의 이동이 간편하여서, 측정자의 편의성을 크게 향상시키게 된다. Therefore, the present invention is able to accurately measure the amount of deformation of the main plate material by the welding deformation without the operator by the laser sensor attached to the running cart. In particular, the amount of deformation is measured on a two-dimensional plane on the back surface of the main plate welded by the reinforcement, but the driving cart travels at a constant speed through the control device, and furthermore, data can be stored and displayed in real time. The light weight of the device makes it easy to move to each measurement section, greatly improving the convenience of the measurer.

이상으로, 본 발명의 바람직한 실시예가 설명되고 도시되었으나, 본 발명은 이러한 실시예에 한정되지 않고, 본 발명의 범주로부터 벗어남 없이 당해 분야의 숙련자라면 다양하게 변형시켜 실시할 수 있음은 물론이다. 또, 본 발명은 용접이면의 변형량을 측정하는 것에 대해 중점적으로 설명하였지만, 실제로 휨 또는 처짐이 발생하는 다른 분야에서도 적절하게 변경하여 사용할 수 있다.As mentioned above, although preferred embodiments of the present invention have been described and illustrated, the present invention is not limited to these embodiments, and those skilled in the art may be variously modified and practiced without departing from the scope of the present invention. Moreover, although this invention demonstrated focusing on measuring the deformation amount of a welding back surface, it can also be suitably changed and used also in the other field | areas which actually produce a bending or a sag.

이상과 같이 본 발명에 의하면, 이동과 설치 및 측정을 1명의 측정자가 수행할 수 있으며, 제어장치의 간단한 조작만으로 측정값을 읽고 데이터의 저장이 가능하여서 측정시간이 절약되게 된다. 특히, 측정을 위한 특정 지점의 값뿐 아니라 주행대차가 이동하는 구간의 전체적인 측정값을 실시간으로 기록할 수 있으며, 간단한 조작으로 한번에 측정이 가능하게 되는 효과가 있게 되어서, 궁극적으로 해당 공정의 품질을 우수하게 유지할 수 있게 된다. According to the present invention as described above, one measurement can be carried out movement, installation and measurement, the measurement time can be saved by reading the measurement value and the data can be stored only by simple operation of the control device. In particular, it is possible to record not only the value of a specific point for measurement but also the overall measured value of the section in which the driving cart moves in real time, and the measurement can be performed at once by simple operation, ultimately improving the quality of the process.
