본 발명은 마찰 교반 점 용접장치에 관한 것으로, 보다 상세하게는 겹쳐져 있는 피가공재와 접촉 상태로 회전함으로써 피가공재를 교반하여 용접하는 마찰 교반 점 용접장치의 회전 공구에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a friction stir spot welding device, and more particularly, to a rotary tool of a friction stir spot welding device which stirs and welds a workpiece by rotating in contact with an overlapping workpiece.

자동차나 항공기 등과 같은 운송장치 그리고 건축/토목 분야 등 다양한 산업분야에서 알루미늄이나 마그네슘 등 경량소재를 활용한 경량합금이 널리 사용되고 있다. 이러한 경량합금을 이용하여 각종 기기, 구조물 등을 생산/제작하기 위해서 는 이들 경량합금을 용접에 의하여 접합하게 되는 경우가 빈발하다. Light alloys using light materials such as aluminum or magnesium are widely used in various industrial fields such as transportation devices such as automobiles and aircrafts and construction / civil engineering. In order to produce / manufacture various devices, structures, etc. using such a light alloy, these light alloys are frequently joined by welding.

따라서 이들 경량합금을 용접하는 기술이 널리 연구되고 있으며, 근래에는 마찰 교반 용접(Friction Stir Welding; FSW)이 소개되어 있고, 이에 관해서는 국제공개문헌(국제공개번호:WO93/10935; 출원인:THE WELDING INSTITUTE)을 참조로 할 수 있다. Therefore, techniques for welding these light alloys have been widely researched, and recently, friction stir welding (FSW) has been introduced, and in this regard, International Publication (WO93 / 10935; Applicant: THE WELDING) INSTITUTE).

상기 문헌을 참조하여 마찰 교반 용접 기술에 대해 간략히 설명하면, 상기한 마찰 교반 용접 기술은 접합하고자 하는 두 개의 피가공재를 서로 맞대어 접합 계면을 따라 공구(tool)가 진행하면서 발생하는 마찰열과 피가공재 내부에서 발생하는 소성 가공 현상을 이용하여 피가공재를 접합하는 방법이다.Briefly describing the friction stir welding technique with reference to the above document, the friction stir welding technique is a friction heat and the inner part of the workpiece generated as the tool progresses along the joining interface against the two workpieces to be joined together It is a method of joining a workpiece using the plastic working phenomenon which arises in.

그리고, 최근에는 이러한 마찰 교반 용접 기술을 활용/개선함으로써 더욱 발전시키고자 하는 노력이 더해지고 있다.In recent years, efforts to further develop by utilizing / improving such friction stir welding technology have been added.

일예로, 상기한 마찰 교반 용접 방법에서 파생된 다른 용접 방법의 하나로 마찰 교반 점 용접 방법이 알려져 있다.As one example, the friction stir spot welding method is known as one of other welding methods derived from the friction stir welding method described above.

상기한 마찰 교반 점 용접 방법은 마찰 교반 용접 현상의 일부분을 이용하여 겹치기 접합에 이용하는 것으로, 회전 공구를 피가공재 쪽으로 이동시켜 한 점(spot)에서 피가공재를 교반하여 용접하는 방법이다.The friction stir spot welding method described above is used for overlapping joining by using a part of friction stir welding phenomenon, and is a method of stirring and welding a workpiece at a spot by moving a rotary tool toward the workpiece.

이러한 마찰 교반 점 용접 방법은 저항 점 용접과 마찰 교반 용접을 혼합한 형태로서, 상기한 마찰 교반 용접과는 다른 용접 방법으로 인식되고 있으며, 스틸(steel)보다 비교적 융점이 낮은 알루미늄이나 마그네슘 등의 비철금속의 접합에 사용되고 있다.The friction stir welding method is a mixture of resistance spot welding and friction stir welding, which is recognized as a different welding method from the friction stir welding, and has a lower melting point than aluminum, such as aluminum or magnesium. It is used for joining.

상기한 마찰 교반 점 용접 방법을 수행하는 용접장치에서는 위에서 설명한 바와 같이 회전 공구를 구비한다.In the welding apparatus which performs the above-mentioned friction stir spot welding method, as described above, a welding tool is provided.

이하, 상기한 회전 공구를 이용하여 마찰 교반 점 용접을 실시하는 방법에 대해 도 1 내지 도 3을 참조하여 설명하면 다음과 같다.Hereinafter, a method of performing friction stir spot welding using the rotary tool will be described with reference to FIGS. 1 to 3.

도 1은 플런징(plunging) 단계를 나타내고, 도 2는 스터링(stirring) 단계를 나타내며, 도 3은 드로잉 아웃(drawing out) 단계를 나타낸다.1 shows a plunging step, FIG. 2 shows a stirring step, and FIG. 3 shows a drawing out step.

일반적으로 회전 공구(100)는 회전축의 단부에 결합되는 숄더(110)와, 숄더(110)와 일체로 구비되는 핀(120)을 포함하여 이루어진다.In general, the rotary tool 100 includes a shoulder 110 coupled to an end of the rotating shaft, and a pin 120 integrally provided with the shoulder 110.

회전 공구(100)를 회전시키면서 핀(120)을 피가공재(130)의 표면에 접촉시키면 핀(120)의 표면과 피가공재(130)의 표면 사이에 마찰열이 발생되고, 발생된 마찰열에 의해 피가공재(130)가 연화된다(플런징 단계).When the pin 120 is brought into contact with the surface of the workpiece 130 while the rotary tool 100 is rotated, frictional heat is generated between the surface of the pin 120 and the surface of the workpiece 130. The workpiece 130 is softened (plunging step).

그리고, 상기 연화가 발생되면 핀(120)에 구비되어 있는 나사 형태의 홈 때문에 소성 유동이 발생된다(스터링 단계).In addition, when the softening occurs, plastic flow occurs due to the threaded groove provided in the pin 120 (stering step).

이때, 상기 소성 유동은 회전 공구(100)의 회전 방향과 수직 방향으로 발생되고, 결과적으로 핀(120) 주위에 존재하는 피가공재(130)는 교반이 발생하여 접합이 이루어진다.At this time, the plastic flow is generated in a direction perpendicular to the rotational direction of the rotary tool 100, and as a result, the workpiece 130 existing around the pin 120 is agitated to be joined.

그런데, 상기한 구성의 회전 공구(100)를 이용하여 마찰 교반 점 용접을 실시할 때에는 숄더(110) 및 핀(120)에서 발생하는 열이 회전축에 전달되므로, 상기 회전축을 포함하는 용접 공구(tool)에 손상이 발생될 수 있다.However, when performing friction stir spot welding using the rotary tool 100 having the above-described configuration, since heat generated from the shoulder 110 and the pin 120 is transferred to the rotary shaft, a welding tool including the rotary shaft (tool) ) May cause damage.

그리고, 피가공재(130)의 두께가 변화할 경우에는 실제 접합에 중요한 부분 인 핀(120)의 길이도 달라져야 하지만, 종래의 회전 공구(100)는 핀(120)이 숄더(110)와 일체로 제조되거나 또는 상기 숄더(120)에 일체로 부착되어 있으므로, 핀의 길이를 조절할 수 없어 회전 공구를 교환해야 하는 문제점이 있다.In addition, when the thickness of the workpiece 130 is changed, the length of the pin 120, which is an important part of the actual bonding, must also be changed. However, in the conventional rotary tool 100, the pin 120 is integrally formed with the shoulder 110. Since it is manufactured or attached integrally to the shoulder 120, there is a problem that can not adjust the length of the pin to replace the rotary tool.

본 발명은 상기한 문제점을 해결하기 위한 것으로, 그 목적은 과도한 마찰열에 의한 손상을 방지할 수 있으며, 피가공재의 두께에 따라 핀 길이 조절이 가능한 회전 공구를 구비하는 마찰 교반 점 용접장치를 제공하는 것이다.The present invention is to solve the above problems, an object thereof is to provide a friction stir welding device having a rotary tool capable of preventing damage due to excessive frictional heat, the pin length is adjustable according to the thickness of the workpiece. will be.
