도면중 수동식 스포트 용접건을 부호1로 나타내었으며, 차체패널(2)을 협지하여 스포트 용접을 행하는 상부전극(3)과 하부전극(4)을 구비하고 있다.In the figure, the manual spot welding gun is indicated by reference numeral 1, and the upper electrode 3 and the lower electrode 4 which hold the body panel 2 and perform spot welding are provided.

상부전극(3)에는 그와 직각방향인 수평으로 돌출하는 수평바(5)가 상하로 이동가능하게 장착되며, 이를위해 수평바(5)의 일단의 고리부(6)에 상부전극(3)이 끼워지고, 고정볼트(7)에 의해 수평바(5)가 상부전극(3)의 임의 위치에 고정되어지게 된다.A horizontal bar 5 protruding horizontally perpendicular to the upper electrode 3 is mounted on the upper electrode 3 so as to be movable upward and downward. For this purpose, the upper electrode 3 is connected to one end of the ring 6 of the horizontal bar 5. Is fitted, and the horizontal bar 5 is fixed to an arbitrary position of the upper electrode 3 by the fixing bolt 7.

그리고 수평바(5) 상에서 슬라이딩 이동 가능한 수직바(8)가 구비되어 있으며, 이 수직바(8)의 상부 고리부(9)에 수평바(5)가 관통하고, 고리부(9)의 바깥측으로부터 고정볼트(10)가 체결되어 수직바(8)를 이동시킬 때에는 고정볼트(10)를 풀고 위치 조정한 후 이동된 위치에 고정시킬때에는 다시 고정볼트(10)를 조인다.A vertical bar 8 which is slidably moved on the horizontal bar 5 is provided. The horizontal bar 5 penetrates the upper ring portion 9 of the vertical bar 8, and the outside of the ring portion 9 is provided. When the fixing bolt 10 is fastened from the side to move the vertical bar (8), loosen the fixing bolt 10 and adjust the position and then tighten the fixing bolt 10 again when fixing to the moved position.

상기 수직바(8)의 하부로는 절연체로 형성되는 스크라이버(11, Scriber)가 접속되며, 스크라이버(11)의 상단은 수직바(8)의 요홈구멍(12)속에 수용되어 스톱퍼(13)(14)에 의해 상호 이탈되지 않도록 구성되어 있다.A scriber 11 (Scriber) formed of an insulator is connected to a lower portion of the vertical bar 8, and an upper end of the scriber 11 is accommodated in the recess hole 12 of the vertical bar 8 to stop the stopper 13. (14) is configured so as not to be separated from each other.

그리고 스크라이버(11)의 상단면과 요홈구멍(12) 상부벽면 사이에는 완충수단(15)이 개재되어 있으며, 이 완충수단은 스크라이버(11)에 의한 패널(2)에의 충격을 완화하기 위하여 실시예와 같이 압축스프링 또는 압축성이 큰 고무탄성체가 바람직하다.A cushioning means 15 is interposed between the upper end surface of the scriber 11 and the upper wall surface of the recess hole 12, and the buffering means is used to mitigate the impact on the panel 2 by the scriber 11. As in the embodiment, a compression spring or a rubber elastic body having a high compressibility is preferable.

상기 스크라이버(11)의 하단은 차체패널(2) 표면에 접촉시 가벼운 마킹을 형성하도록 날카롭게 형성하거나 또는 금속체에 의한 영구 표식을 방지하기 위하여 크레용 등의 필기구(16)를 하단에 협지토록 구성되어 있다.The lower end of the scriber 11 is formed so as to sharply form a light marking upon contact with the surface of the body panel 2 or to sandwich the writing instruments 16 such as crayons at the lower end to prevent permanent marking by a metal body. It is.

이와같은 본 발명의 구성에 의해 용접 포인트를 지시 및 표시하는 과정을 설명하면 다음과 같다.Referring to the process of indicating and displaying the welding point by the configuration of the present invention as follows.

용접하고자 하는 2장의 패널(2)의 용접 포인트에 맞추어 상하전극(3)(4)을 위치시킨다.The upper and lower electrodes 3 and 4 are positioned in accordance with the welding points of the two panels 2 to be welded.

그러나 그전에 먼저 용접 포인트들 사이의 피치가 결정되었다면 패널(2)의 평탄상태를 관찰하여 최초 용접 포인트에 대한 다음 용접 포인트의 지면으로부터의 상대적 높이를 고려하여 고정볼트(7)를 통하여 수평바(5)의 높이를 조정한 후 고정시킨다.However, if the pitch between the welding points was determined before, the horizontal bar (5) through the fixing bolt (7) was observed by considering the flat state of the panel (2) and taking into account the relative height from the ground of the next welding point to the initial welding point. After adjusting the height, fix it.

그리고 나서 상하전극(3)(4)으로부터 일정거리 위치인 수평바(5)상으로 수직바(8)를 이동시켜 고정시키게 되면 용접 포인트의 피치가 정확히 설정되는 것이다.Then, when the vertical bar 8 is fixed by moving the vertical bar 8 on the horizontal bar 5 at a predetermined distance from the upper and lower electrodes 3 and 4, the pitch of the welding point is accurately set.

이 상태에서 패널(2)의 최초 용접 포인트에 상하전극(3)(4)을 대고 압압하면서 고전압을 공급하면 스포트 용접이 행해지게 된다.In this state, spot welding is performed when high voltage is supplied while pressing the upper and lower electrodes 3 and 4 to the first welding point of the panel 2.

여기서 다음 용접 포인트의 높이가 최초 용접 포인트 보다 낮으면 스크라이버(11)는 그의 하단이 패널(2) 표면에 압착할 때까지 완충수단(15)에 의해 하강하며, 반대로 높을때에는 차체패널(2)에 의해 밀어올려져 스크라이버(11)가 완충수단(15)을 압축하면서 상승하게 된다.Here, if the height of the next welding point is lower than the initial welding point, the scriber 11 is lowered by the buffer means 15 until its lower end is pressed against the surface of the panel 2, and conversely, when the height is higher, the body panel 2 It is pushed up by the scriber 11 is raised while compressing the buffer means (15).

이로써 패널(2) 표면에는 적정량의 탄성력으로 스크라이버(11)가 접촉하게 되므로 스크라이버(11)의 누룸력에 의해 패널(2)이 변형하는 일이 없게 된다.As a result, the scriber 11 comes into contact with the surface of the panel 2 with an appropriate amount of elastic force, so that the panel 2 does not deform due to the pressing force of the scriber 11.

한편 스크라이버(11)의 하단을 날카로운 송곳형태로 형성하였다면 패널(2) 표면에는 용접작업자가 인식할 수 있는 점형태의 용접 포인트가 가볍게 마킹되며, 품질문제상 점상의 마킹이 허용되지 않을 경우 분필 등의 필기구(16)에 의해 용접 포인트를 표시하면 나중에 지울수 있기 때문에 패널(2) 표면에 전혀 흔적을 남기지 않으면서 다음 용접 포인트의 표시가 가능하다.On the other hand, if the bottom of the scriber 11 is formed in the shape of a sharp awl, the surface of the panel 2 is lightly marked with a point-shaped welding point that can be recognized by the welding worker. If the welding point is marked by the writing instrument 16, etc., it can be erased later, so that the next welding point can be displayed without leaving any trace on the panel 2 surface.

따라서 최초 용접 포인트에의 용접작업이 완료하면 작업자는 용접건(1)의 상하전극(3)(4)을 앞서 마킹된 위치로 이동시켜 용접작업을 진행하게 되며, 계속되는 용접 작업들도 앞서와 동일하게 진행된다.Therefore, when the welding work to the first welding point is completed, the worker moves the upper and lower electrodes 3 and 4 of the welding gun 1 to the previously marked position and proceeds the welding work, and the subsequent welding work is the same as before. Proceeds.

이상과 같은 본 발명은 수동식 용접건에 상하 이동이 자유로운 수평바와, 수평바를 따라 이동이 자유로운 수직바 및 수직바에 대하여 완충되는 스크라이버를 구비하고 있어, 어느 한 지점의 스포트 용접이 진행될 때 다음 스포트 용접 포인트를 정확히 지시하게 되므로써 별도의 피치 마킹이 불필요하여 작업시간과 인력이 감소되고 장치의 구조가 극히 단순한 반면 고가의 용접로봇의 기능을 수행할 수 있어 설비비용의 저감이 가능하다.As described above, the present invention includes a horizontal bar freely moving up and down in the manual welding gun, and a scriber buffered against the vertical bar and the vertical bar freely moving along the horizontal bar, when the spot welding at any point proceeds to the next spot welding. By precisely indicating the point, no separate pitch marking is required, which reduces work time and manpower, and the structure of the device is extremely simple, while it can perform the function of expensive welding robot, thus reducing the equipment cost.
