Title
(EN) SPOT WELDING DEVICE, POSITION OF WHICH IS EASILY CHANGEABLE
(FR) DISPOSITIF DE SOUDAGE PAR POINTS DONT LA POSITION EST FACILEMENT MODIFIABLE
(KO) 포지션 변경이 용이한 스폿 용접장치
Abstract
(EN) Disclosed is a spot welding device, which is manually usable and requires no large force when used, and the position of which is easily changeable. The spot welding device according to an embodiment comprises: an air balance including multiple arms coupled in the form of a multi-step structure and an air cylinder for driving the multiple arms, wherein an arm located at the outermost side among the multiple arms includes a first tool changer; and a spot welding unit including a second tool changer coupled to the first tool changer.
(FR) Est divulgué un dispositif de soudage par points, qui peut être utilisé manuellement et ne nécessite pas de force importante lorsqu'il est utilisé, et dont la position est facilement modifiable. Le dispositif de soudage par points, selon un mode de réalisation, comprend : un système de levage pneumatique comprenant de multiples bras accouplés sous forme de structure à étages multiples et un vérin pneumatique destiné à entraîner les multiples bras, un bras situé du côté le plus à l'extérieur parmi les multiples bras comprenant un premier changeur d'outil ; et une unité de soudage par points comprenant un second changeur d'outil accouplé au premier changeur d'outil.
(KO) 수동으로 사용할 수 있되, 사용시 큰 힘이 필요하지 않고, 포지션 변경이 용이한 스폿 용접장치를 개시한다. 실시예에 따른 스폿 용접장치는 다단 구조로 결합되는 복수 개의 암과, 상기 복수 개의 암을 구동하는 에어실린더를 포함하고, 상기 복수 개의 암 중 최외측에 위치한 암에 제1 툴체인저가 구비된 에어밸런스; 및 상기 제1 툴체인저에 결합되는 제2 툴체인저를 구비한 스폿용접유닛;을 포함한다.
