Description

박판접합용 고정장치{A FIXTURE FOR BRAZING A THIN STEEL}A FIXTURE FOR BRAZING A THIN STEEL}

본 발명은 박판을 접합하는데 사용되는 고정장치에 관한 것으로, 보다 상세히는 박판을 접합할 때 정확하게 두 개의 박판소재를 일정한 압력으로 정밀하게 고정하고, 소재의 응력변형을 최소화하여 용접작업성을 향상시킬 수 있는 박판접합용 고정장치에 관한 것이다.The present invention relates to a fixing device used to join the thin plate, and more specifically, to accurately bond two thin plate materials at a constant pressure when joining the thin plate, and to improve the workability by minimizing the stress deformation of the material The present invention relates to a fastening device for thin plate bonding.

일반적으로 박판을 접합하는 작업은 박판시편의 양 끝에 태그(Tag)용접을 하거나 도 1에 도시한 바와같이, 베이스(1)와 고정지그(3)사이에 눌러 고정한 다음 서로 맞닿는 부위를 용접하여 접합하였다.In general, the operation of joining a thin plate is performed by tag welding at both ends of the thin plate specimen or as shown in FIG. 1, pressing and fixing between the base 1 and the fixing jig 3, and then welding the portions that are in contact with each other. It was.

즉, 박판을 접합하도록 고정하는 종래 고정장치(100)는 바닥면에 배치되어 접합하고자 하는 박판(5)이 상부면에 올려지는 베이스(1)와, 좌우양단에 하부단이 상기 베이스(1)에 나사결합된 고정나사(3)를 갖는 고정지그(2)를 갖춤으로서, 상기 베이스(1)와 고정지그(2)사이에 배치된 박판(5)을 고정하도록 상기 나사(3)를 정방향으로 회전시켜 상기 고정지그(2)를 베이스(1)측으로 하강시켜 가압하여 고정한 다음, 서로 맞닿는 부위를 용접하여 연결하였다.That is, the conventional fixing device 100 for fixing the thin plate is placed on the bottom surface to be bonded to the base plate (1) is placed on the upper surface and the lower end is the base (1) By having a fixing jig 2 having a fixing screw 3 screwed to it, the screw 3 in a forward direction to fix the thin plate 5 disposed between the base 1 and the fixing jig 2. The fixing jig 2 was lowered to the base 1 side by rotation to press and fix the fixed jig 2, and then welded portions were connected by welding.

그러나, 이러한 종래의 방법들은 박판전체의 변형을 거시적으로 방지할 수는 있지만 국부적인 변형을 방지할 수는 없기 때문에 판두께가 얇은 박판으로 갈수록 용접변형을 방지하지 못하는 문제점을 안고 있었다.However, these conventional methods have a problem that the deformation of the entire thin plate can be prevented macroscopically, but the local deformation cannot be prevented, so that welding deformation cannot be prevented as the plate thickness becomes thinner.

그리고, 상기 고정지그(2)를 하강시켜 박판을 고정하는 경우, 상기 고정나사(3) 및 고정지그(2)의 기계가공 공차로 인하여 상기 베이스(1),고정지그(2)의 표면과 접하는 박판(5)표면간의 물림편차가 일정하지 않고, 용접선의 길이가 길수록 편차로 인하여 정확한 박판고정이 곤란하기 때문에, 용접접합후 두 개의 박판이 평면상으로 용접이 되지 않는 결과를 초래하게 된다.And, when fixing the thin plate by lowering the fixing jig (2), due to the machining tolerances of the fixing screw (3) and the fixing jig (2) in contact with the surface of the base (1), fixing jig (2) Since the bite deviation between the surfaces of the thin plate 5 is not constant and the longer the length of the welding line is, it is difficult to accurately fix the thin plate due to the variation, resulting in the two thin plates not being welded on the plane after welding.

또한, 상기 박판(5)은 상기 베이스(1)와 고정지그(2)사이에서 판두께가 가장 두꺼운 부위만 접촉되어 고정력을 발생시키고, 판두께가 얇은 부위는 고정력이 발생되지 않기 때문에 서로 접하는 박판(5)간의 용접시 상기 고정지그(2)에 의해 고정되지 않는 부위가 변형되어 용접불량을 초래하였다.In addition, the thin plate 5 is in contact with only the thickest portion of the plate thickness between the base 1 and the fixing jig 2 to generate a fixing force, the thin plate portion is in contact with each other because the fixing force does not occur When welding between (5), the part which is not fixed by the said fixing jig 2 deform | transformed, and caused the welding defect.

그리고, 스테인레스 강판과 열팽창계수가 큰 박판소재들은 항복강도가 낮기 때문에, 판두께 편차에 의하여 상기 고정지그(2)에 의한 고정이 균일하게 되지 않으면 응력상태와 국부적인 용접변형에 의하여 용접선의 중심이 상하로 변형되기 쉽고, 이러한 현상은 두께가 얇은 박판일수록 현저하게 나타나기 때문에, 가공정도가 좋은 고정지그(2)를 사용하여 고정하지 않으면 안된다.In addition, since stainless steel sheet and sheet materials having a high coefficient of thermal expansion have low yield strength, the center of the weld line is changed by the stress state and local welding deformation unless the fixing jig is uniformly fixed due to the plate thickness variation. It is easy to be deformed up and down, and this phenomenon is more remarkable as the thin plate is thin, so it is necessary to fix it using the fixing jig 2 having good processing accuracy.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해소하기 위하여 제안된 것으로서, 그 목적은 열팽창계수가 큰 박판소재를 용접선을 따라 항상 일정한 응력으로 고정하여 용접시 열변형을 최소화시킬 수 있고, 박판소재의 전 용접선에 걸쳐 용접열을 흡수하여 용접접합부의 변형을 방지하여 박판용접성을 향상시킬 수 있는 박판접합용 고정장치를 제공하고자 한다.Therefore, the present invention has been proposed to solve the conventional problems as described above, the object of which is to fix the sheet material having a large coefficient of thermal expansion with a constant stress at all times along the welding line to minimize thermal deformation during welding, sheet material It is intended to provide a thin plate joint fixing device that can improve the thin plate weldability by absorbing the welding heat over the entire weld line to prevent deformation of the weld joint.

본 발명의 장치(200)는 도 2 내지 5에 도시한 바와같이, 열팽창계수가 큰 박판소재를 베이스(1)상에 올려놓고, 고정지그(2)의 고정나사(3)로서 박판소재(5)를 고정할 때 용접하고자 하는 용접선을 따라 일정한 응력으로 고르게 고정함과 동시에 용접시 열변형을 방지하여 용접작업성을 향상시키고, 용접불량을 예방할 수 있는 것으로서, 이러한 장치(200)는 이동부(20) 및 보조고정부(40)로 구성된다.In the apparatus 200 of the present invention, as shown in Figs. 2 to 5, a thin plate material having a large coefficient of thermal expansion is placed on the base 1, and the thin plate material 5 as a fixing screw 3 of the fixing jig 2 is placed. In order to fix the same evenly along the welding line to be welded at the same time to prevent the heat deformation during welding to improve the workability of welding, and to prevent welding failure, such a device 200 is a moving part ( 20) and the auxiliary fixing part 40.

즉, 상기 고정지그(2)의 위치를 안내이동시키는 이동부(20)는 직육면체상의 바부재로 이루어진 고정지그(2)의 좌우양단부근에 각각 나사결합된 고정나사(3)의 하부단에 이동블록(21)을 장착한다.That is, the moving part 20 for guiding the position of the fixing jig 2 is moved to the lower end of the fixing screw 3 which is respectively screwed around the left and right ends of the fixing jig 2 made of a rectangular bar member. Mount the block 21.

상기 이동블록(21)은 상기 고정나사(3)의 하부단에 형성된 원반형 걸림턱(3a)이 상부이탈이 곤란하도록 삽입되는 요홈(22)이 형성되고, 상기 걸림턱(3a)이 삽입되는 상기 이동블록(21)의 일측면은 상기 걸림턱(3a)의 수평방향으로 이탈이 곤란하도록 복수개의 체결부재(21b)로서 엔드플레이트(21a)가 조립되어 밀폐된다.The movable block 21 is formed with a groove 22 into which the disk-shaped locking jaw 3a formed at the lower end of the fixing screw 3 is inserted so that it is difficult to separate the upper portion, and the locking jaw 3a is inserted. One side of the movable block 21 is sealed by assembling the end plate 21a as a plurality of fastening members 21b so as to be difficult to separate in the horizontal direction of the locking step 3a.

그리고, 상기 베이스(1)의 상부면 좌우양측 테두리부근에는 'Ｔ'자 단면상을 갖는 이동블록(21)과 동일한 단면상을 갖는 안내홈(23)을 길게 함물형성하며, 상기안내홈(23)에는 상기 고정나사(3)의 각 하부단에 조립되는 이동블록(21)이 각각 배치된다. 이에 따라, 상기 고정지그(2)는 상기 안내홈(23)을 따라 고정위치를 적절히 가변시킬 수 있도록 간편하고 신속하게 수평이동될 수 있는 것이다.In addition, a guide groove 23 having the same cross-sectional shape as that of the moving block 21 having a 'T' cross-section is formed near the left and right edges of the upper surface of the base 1, and the guide groove 23 is formed in the guide groove 23. Moving blocks 21 are assembled to the lower ends of the fixing screw 3, respectively. Accordingly, the fixing jig 2 can be easily and quickly horizontally moved to appropriately change the fixing position along the guide groove 23.

또한, 접합하고자 하는 박판소재(5)를 폭방향으로 고르게 고정하는 보조고정부(40)는 상기 고정지그(2)의 좌우양단에 각각 조립되는 고정나사(3)사이에 적어도 하나이상의 보조나사(41)를 배치할 수 있도록 상기 고정지그(2)의 몸체상부면에 복수개의 암나사공(41a)을 관통형성하며, 상기 암나사공(41a)은 스프링부재(42)와 볼조인트(43)가 수용되는 장착공(45)과 연통된다.In addition, the auxiliary fixing portion 40 for evenly fixing the thin plate material 5 to be bonded in the width direction is at least one auxiliary screw (3) between the fixing screw (3) respectively assembled at the left and right ends of the fixing jig (2) A plurality of female threaded holes 41a are formed through the upper surface of the body of the fixing jig 2 so that 41 can be disposed, and the female threaded holes 41a are accommodated by the spring member 42 and the ball joint 43. It is in communication with the mounting hole 45.

그리고, 상기 스프링부재(42)는 상기 보조나사(41)의 하부단에 접하여 항상직하방으로 탄력지지되고, 상기 스프링부재(42)의 탄성력에 의해서 직하방으로 탄력지지되는 볼조인트(43)에는 접합하고자 하는 박판소재(5)의 상부면과 하부면이 접하는 고정판(44)을 360°자유롭게 회전시킬 수 있도록 조립구성한다.The spring member 42 is always elastically supported in direct contact with the lower end of the auxiliary screw 41 and is elastically supported in the ball joint 43 by the elastic force of the spring member 42. The upper and lower surfaces of the thin plate material 5 to be bonded are assembled to be able to rotate 360 ° freely rotating the fixed plate (44).

여기서, 상기 고정판(44)은 용접시 발생되는 용접열을 흡수하도록 구리소재로 구성되는 것이 좋다.Here, the fixing plate 44 is preferably made of a copper material to absorb the welding heat generated during welding.

본 발명의 장치(200)를 이용하여 선,후박판소재(5)를 용접접하고자 하는 경우, 먼저 용접대상물인 선,후박판소재(5)의 선,후단부가 맞닿도록 베이스(1)상에 올려놓고, 상기 고정지그(2)의 고정나사(3)하부단에 조립된 이동블록(21)을 베이스(1)의 안내홈(23)을 따라 수평이동시켜 상기 박판소재(5)를 고정하기 위한 고정지그(2)의 고정위치를 결정한다.In the case of using the apparatus 200 of the present invention to weld the line and the thick plate material 5, first, the line to be welded, the line and the rear end of the thick plate material 5 are brought into contact with each other on the base 1. Put up and fix the thin plate material 5 by horizontally moving the moving block 21 assembled at the lower end of the fixing screw 3 of the fixing jig 2 along the guide groove 23 of the base 1. Determine the fixing position of the fixing jig (2).

이러한 상태에서, 상기 고정나사(3)를 체결방향으로 회전시키면, 상기 고정지그(2)의 하부면과 베이스(1)의 상부면간의 간격이 좁아지면서 상기 고정지그(2)와 베이스(1)사이에 배치된 박판소재(5)를 고정하게 된다.In this state, when the fixing screw 3 is rotated in the fastening direction, the interval between the lower surface of the fixing jig 2 and the upper surface of the base 1 is narrowed, and the fixing jig 2 and the base 1 are narrowed. The thin plate material 5 disposed in between is fixed.

이때, 상기 박판소재(5)의 표면을 전폭에 걸쳐서 미압착부의 발생없이 일정한 힘으로 고르게 고정하고자 경우, 좌우한쌍의 고정나사(3)사이에 배치된 보조나사(41)를 상기 고정나사(3)와 동일한 체결방향으로 회전시키면, 상기 보조나사(41)의 하부단에 접하고, 상기 고정지그(2)의 장착공(45)내에 수용된 스프링부재(42)가 압축되기 때문에, 상기 스프링부재(42)와 더불어 상기 장착공(45)내에 수용된 볼조인트(43)를 직하부로 가압하기 시작한다.At this time, in order to fix the surface of the thin plate material 5 evenly with a constant force without the occurrence of uncompressed portions over the entire width, the auxiliary screw 41 disposed between the left and right pair of fixing screws (3) the fixing screw (3) When rotating in the same fastening direction as), the spring member 42 is in contact with the lower end of the auxiliary screw 41, and the spring member 42 accommodated in the mounting hole 45 of the fixing jig 2 is compressed. And pressurizes the ball joint 43 accommodated in the mounting hole 45 directly below.

이러한 경우, 상기 볼조인트(43)에는 상기 박판소재(5)의 상부면에 하부면이면접하는 고정판(44)의 연결부가 360°자유롭게 회전되도록 연결되어 있기 때문에, 상기 박판소재(5)를 폭방향으로 미압착부의 발생없이 고르게 압착고정함과 동시에 일정한 응력이 항상 수직방향으로 유지되도록 하여 안정된 고정력을 확보할수 있다.In this case, since the connecting portion of the fixing plate 44 which is in contact with the lower surface on the upper surface of the thin plate material 5 is rotated 360 degrees freely, the thin plate material 5 is wide. It is possible to secure stable clamping force by evenly compressing and fixing evenly without the occurrence of uncompressed part in the direction and maintaining constant stress in the vertical direction at all times.

또한, 상기 고정지그(2) 및 고정판(44)으로서 박판소재(5)를 고정하여 용접할 때 발생되는 용접열은 열흡수율이 좋은 고정판(44)에 의해서 흡수되기 때문에 박판소재(5)의 응력변형을 최소화하면서 용접선을 따라 용접비드(B)를 고르게 형성하여 용접작업을 종료할수 있는 것이다.In addition, since the welding heat generated when the thin plate material 5 is fixed and welded by the fixing jig 2 and the fixing plate 44 is absorbed by the fixing plate 44 having good heat absorption rate, the stress of the thin plate material 5 By minimizing deformation, the welding bead (B) is evenly formed along the welding line to terminate the welding operation.

상술한 바와같은 본 발명에 의하면, 고정지그를 길이방향으로 간편하고 신속하게 베이스상에 수평이동시킴으로서, 박판소재를 폭방향으로 고정하는 위치를 자유롭게 가변시킬 수 있어 용접작업성을 향상시킬 수 있고, 박판소재의 상부면에 접하는 고정판을 두께공차에 의해서 박판폭방향으로 미압착부가 발생되지 않도록 스프링부재의 탄성력에 의해서 일정한 응력으로 고르게 고정함 동시에 용접시 용접열을 흡수함으로서, 박판소재가 동일한 평면상에서 정밀하게 용접되고, 응력변형을 최소화하여 용접작업성을 현저히 향상시킬 수 있는 효과가 얻어진다.According to the present invention as described above, by simply and quickly horizontally moving the fixing jig in the longitudinal direction on the base, the position for fixing the thin plate material in the width direction can be freely changed to improve the welding workability, The plate is fixed on the same plane by absorbing the welding heat during welding while fixing the fixing plate in contact with the upper surface of the thin plate material by the elasticity of the spring member to prevent uncompressed parts from occurring in the thin plate width direction due to the thickness tolerance. It is welded precisely, and the effect of remarkably improving welding workability by minimizing stress deformation is obtained.
