Description
본 발명은 고정식 스폿 용접기에 관한 것으로, 보다 상세하게는 자동차 제조공장 등에서 강판을 겹쳐서 스폿 용접(Spot welding)을 하기 위해 사용되는 포터블 용접기(Portable welding machine)를 고정식으로 구성하므로써 설비투자비와 설치공간이 적고, 특히 소형물 용접시에 작업성이 향상되고 용접불량이 방지되도록 한 고정식 스폿 용접기에 관한 것이다.The present invention relates to a fixed spot welding machine, and more particularly, a portable welding machine used to perform spot welding by overlapping steel sheets in an automobile manufacturing plant, etc., has a fixed capital investment and installation space. In particular, the present invention relates to a fixed spot welder which improves workability and prevents welding defects, especially when welding a small object.
일반적으로, 자동차 제조공장 등에서 강판을 겹쳐서 스폿 용접을 하기 위해 사용되는 포터블 용접기는 첨부 도면 도 1에 도시한 바와 같이 일정한 높이를 설치된 비임(Beam)(10)에 트랜스포머(Transfomer)(12)가 매달려 설치되고 상기 트랜스포머(12)에 연결된 킥크리스 케이블(Kickless cable)(14)에는 용접건(Welding gun)(16)이 설치되어 있다.In general, a portable welding machine used for spot welding by overlapping steel sheets in an automobile manufacturing plant, etc., has a transformer 12 suspended on a beam 10 having a fixed height as shown in FIG. 1. A welding gun 16 is installed on the kickless cable 14 installed and connected to the transformer 12.
한편, 전원공급장치(미도시)로부터 상기 트랜스포머(12)에 전달된 고압의 전류는 상기 킥크리스 케이블(14)을 통하여 상기 용접건(16)에 통전되도록 되어 있으며 또한 상기 킥크리스 케이블(14)은 고압의 전류가 흐르도록 일정한 외경으로 형성되고 그 내부에는 용접시 용접건(16)에 발생하는 고온의 열을 냉각시키기 위해 냉각라인이 매설되는 한편, 상기 용접건(16)의 작업반경에 따라 일정한 길이로 형성된다.On the other hand, the high-voltage current transmitted from the power supply (not shown) to the transformer 12 is to be energized to the welding gun 16 through the kick criss cable 14 and the kick criss cable 14 Is formed to have a constant outer diameter so that a high-pressure current flows therein, and a cooling line is embedded therein to cool the high temperature heat generated in the welding gun 16 during welding, and according to the working radius of the welding gun 16. It is formed to a certain length.
그리고, 상기 용접건(16)과 킥크리스 케이블(14)에는 상기 비임(10)에 설치된 스프링 발란서(Spring balancer)(18)가 연결되어 상기 용접건(16)과 킥크리스 케이블(14)의 하중을 지지하여 일정한 높이로 매달린다.In addition, a spring balancer 18 installed at the beam 10 is connected to the welding gun 16 and the kickless cable 14 to connect the welding gun 16 and the kickless cable 14. Support the load and hang it to a certain height.
한편, 상기와 같이 설치된 포터블 용접기(20)를 이용하여 용접작업을 하고자 할 때는 작업자가 상기 용접건(16)을 잡고 상하 좌우 전후 방향으로 움직이면서 용접 지그(22)에 결합된 부재를 용접하게 되는 것이다.On the other hand, when the welding operation is to be performed using the portable welding machine 20 installed as described above, the operator is holding the welding gun 16 to move the member coupled to the welding jig 22 while moving in up, down, left and right directions. .
그러나, 상기와 같은 종래 고정식 스폿 용접기(20)는 작업자가 용접할 부재를 용접 지그(22)에 장착한 다음 무거운 용접건(16)을 잡고 움직이면서 작업을 해야하므로 작업성이 나쁘고 또한 용접할 부재를 고정할 별도의 용접 지그(22)가 필요하며 트랜스포머(12) 등을 매달기 위한 비임(10) 등을 설치해야 되므로 설비투자비가 증가되고 설치공간을 많이 차지하는 단점이 있다.However, the conventional stationary spot welder 20 as described above has a bad workability and requires a member to mount the member to be welded to the welding jig 22 and then hold and move the heavy welding gun 16 to perform the work. Since a separate welding jig 22 to be fixed is required and a beam 10 for hanging the transformer 12 and the like must be installed, the facility investment cost increases and occupies a lot of installation space.
특히, 용접할 부재가 작을 경우에는 용접건(16)의 진입시에 간섭발생으로 용접 포인트를 정확히 찾을 수 없어서 용접불량이 발생되고 작업성이 저감되는 문제점이 있었다.In particular, when the member to be welded is small, there is a problem in that welding defects are not found accurately due to interference when entering the welding gun 16, resulting in poor welding and workability.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 그 목적은 설비투자비와 설치공간이 적고, 특히 소형물 용접시 작업성이 향상되고 용접불량이 방지되도록 한 고정식 스폿 용접기를 제공하고자 하는 것이다.The present invention has been made to solve the above problems, and its object is to provide a fixed spot welder that has a small capital investment cost and installation space, in particular, improves workability and prevents welding defects when welding small objects.
이러한, 목적을 달성하기 위하여, 본 발명은 타이머 및 트랜스포머와 상기 트랜스포머에 연결된 킥크리스 케이블과, 상기 킥크리스 케이블에 연결된 용접건으로 구성되고, 상기 타이머 및 트랜스포머가 테이블상에 올려져 장착되며, 상기 용접건이 테이블상에 체결되는 고정브라켓트에 고정 결합된 포터블 용접기에 있어서, 상기 고정브라켓트는 상기 용접건의 설치 높낮이가 조정되도록, 직사각 형상을 갖는 부재에 상하방향으로 장공 형상의 가이드홈이 천공된 한 쌍의 지지부재와, 상기 지지부재의 가이드홈에 삽입되어 상기 용접건에 체결되는 고정수단으로 이루어진 것을 특징으로 한다.In order to achieve the above object, the present invention is composed of a timer and a transformer, a kickless cable connected to the transformer, and a welding gun connected to the kickless cable, and the timer and transformer are mounted on a table, and the welding In a portable welding machine fixedly coupled to a fixed bracket to which a gun is fastened on a table, the fixed bracket is a pair of guide holes having a long hole shape formed in a rectangular shape on a member having a rectangular shape so that the installation height of the welding gun is adjusted.

도 2는 본 발명에 따른 고정식 스폿 용접기를 나타내는 개략적인 정면도로서, 이에 도시한 바와 같이 타이머(Timer)(32) 및 트랜스포머(34)와 상기 트랜스포머(34)에 연결된 킥크리스 케이블(36)과, 상기 킥크리스 케이블(36)에 연결된 용접건(38)을 포함하여 이루어진 포터블 용접기에 있어서, 상기 타이머(32) 및 트랜스포머(34)가 설치되도록 일정한 넓이를 갖도록 대략 사각형 형상으로 형성된 상판상에 일정한 높이를 갖는 다수 개의 다리가 설치된 테이블(40)과, 상기 테이블(40)의 상면 상에 설치되어 상기 용접건(38)이 장착되는 고정브라켓트(42)가 구성된 것이다.Figure 2 is a schematic front view showing a fixed spot welder according to the present invention, as shown therein, a timer 32 and a transformer 34 and a kickless cable 36 connected to the transformer 34, In the portable welding machine comprising a welding gun 38 connected to the kick cable 36, a constant height on a top plate formed in a substantially rectangular shape to have a constant width so that the timer 32 and the transformer 34 are installed. Table 40 is installed with a plurality of legs having a fixed bracket 42 is installed on the upper surface of the table 40 is mounted to the welding gun 38.
한편, 상기 고정브라켓트(42)는 상기 용접건(38)의 설치 높낮이가 조정되도록 일정한 폭과 길이를 갖는 직사각형상의 부재에 상하방향으로 장공 형상의 가이드홈(42c)이 천공된 한 쌍의 지지부재(42a)와, 상기 지지부재(42a)의 가이드홈On the other hand, the fixing bracket 42 is a pair of supporting members in which the long groove-shaped guide grooves 42c are drilled in a vertical member having a predetermined width and length so that the installation height of the welding gun 38 is adjusted. 42a and guide grooves of the support member 42a.
(42c)에 삽입되어 상기 용접건(38)에 체결되는 고정수단(42b)으로 이루어진다.And a fixing means 42b inserted into 42c and fastened to the welding gun 38.
또한, 상기 용접건(38)에는 용접 신호를 인가시키는 풋트 스위치(44)가 연결되어 설치된다.In addition, a foot switch 44 for applying a welding signal is connected to the welding gun 38.
상기와 같은 본 발명의 작용은 다음과 같다.The operation of the present invention as described above is as follows.
도 2에 도시한 바와 같이, 고정식 스폿 용접기(30)를 이용하여 용접작업을 하고자 할 때는 작업자가 손이나 소정의 지그(46)로 용접할 부재를 잡은 다음 용접건(38)의 용접 샹크 사이에 부재를 삽입하고 풋트 스위치(44)를 밟게 되면 스폿 용접이 이루어지게 되는 것이다.As shown in FIG. 2, when performing a welding operation using the fixed spot welder 30, an operator grasps a member to be welded with a hand or a predetermined jig 46, and then between welding shanks of the welding gun 38. When the member is inserted and the foot switch 44 is pressed, spot welding is performed.
한편, 용접할 부재의 크기가 작을 경우에는 손을 상하 좌우로 움직이면서 간편하게 용접을 할 수 있으며, 또한 용접건(38)이 테이블(40)에 설치된 고정브라켓트(42)에 고정되어 있으므로 작업자가 무거운 용접건(38)을 직접 들지 않고 작업할 수 있으며, 또한 고정브라켓트(42)에 장착된 용접건(38)의 높낮이를 작업자의 신체조건에 맞도록 조정하여 작업할 수 있으므로 작업의 피로도가 적고 작업성이 향상되는 것이다.On the other hand, when the size of the member to be welded is small, the hand can be easily welded while moving up, down, left, and right, and the welding gun 38 is fixed to the fixing bracket 42 installed on the table 40. It is possible to work without lifting the gun 38 directly, and also to adjust the height of the welding gun 38 mounted on the fixing bracket 42 to suit the physical condition of the worker so that the work is less fatigued and workable. This is to be improved.
상기와 같은 본 발명에 따른 고정식 스폿 용접기에 의하면, 타이머나 트랜스포머와 같은 설비들을 매달기 위한 비임 등과 같은 부속설비들이 불필요하게 되고 동시에 설치공간이 필요없게 되므로 설비투자비가 감소하며, 작업자가 용접할 부재를 용접지그에 장착한 다음 용접건을 직접 잡고 움직이면서 작업할 필요가 없게 되므로 작업성이 향상되고, 특히 용접할 부재가 작을 경우에도 부재를 손으로 잡고 상하 좌우로 움직이면서 정확한 위치에 용접을 할 수 있게 되어 용접불량이 방지되는 동시에 고정브라켓트에 장착된 용접건의 높낮이를 작업자의 신체조건에 맞도록 조정하여 작업할 수 있는 효과가 있다.According to the fixed spot welding machine according to the present invention as described above, the equipment investment cost is reduced, because the installation equipment such as a beam for hanging the equipment such as a timer or transformer is unnecessary and at the same time does not need the installation space, the member to be welded by the worker Is mounted on the welding jig and there is no need to hold and move the welding gun directly, thus improving workability. As the welding defect is prevented, the height of the welding gun mounted on the fixing bracket can be adjusted to suit the physical condition of the worker.
