본 발명은 불균일한 개선 갭을 홈가공(절삭)하고, 그 홈에 충전재(공금)를 삽입하여 부재와 충전재의 3자를 마찰교반접합하는 방법에 있어서, 절삭 커터의 안전커버 내의 절삭 찌꺼기의 제거에 관한 방법 및 안전커버에 관한 것이다.The present invention provides a method of grooving (cutting) a non-uniform improvement gap, inserting a filler (metal plate) into the groove, and friction stir welding the three members of the member and the filler to remove the cutting chips in the safety cover of the cutting cutter. It relates to a method and a safety cover.

인용문헌 1과 같이, 커터로 홈을 절삭한 경우, 절삭 찌꺼기가 생긴다. 이 절삭 찌꺼기는 일반적으로 흡인으로 처리하고 있다.As in Reference Document 1, when the groove is cut by a cutter, cutting chips are generated. This cutting waste is generally treated by suction.

[특허문헌 1][Patent Document 1]

일본국 특개2001-210571호 공보Japanese Patent Application Laid-Open No. 2001-210571

그러나 유인하지 않은 경우, 커터는 안전커버로 덮여져 있어, 절삭 찌꺼기가 이 커버 내에 축적되고, 그 결과, 축적된 절삭 찌꺼기가 홈에 접촉하여, 홈 내로 절삭 찌꺼기가 밀어 넣어지는 현상이 발생한다. 절삭 찌꺼기가 홈 내로 들어 오면, 홈 내로의 충전재의 삽입이 곤란해지고, 나아가서는 접합이 불가능하게 된다.However, if it is not attracted, the cutter is covered with a safety cover, whereby cutting chips accumulate in this cover, and as a result, the accumulated cutting debris comes into contact with the grooves, and the cutting debris is pushed into the grooves. When the cutting debris enters the grooves, it becomes difficult to insert the filler into the grooves, and furthermore, the joining becomes impossible.

본 발명의 목적은 홈가공에 있어서 발생하는 절삭 찌꺼기를 안전커버 내로부터 효율좋게 제거함으로써, 상기 접합불량을 방지하는 것에 있다.An object of the present invention is to prevent the above bonding failure by efficiently removing the cutting residues generated in the groove processing from the inside of the safety cover.

상기 목적을 달성하기 위하여, 본 발명은 기본적 수단으로서, 사이드 커터에 의해 대상워크를 홈 가공할 때에 발생하는 절삭 찌꺼기를 사이드 커터 주변을 둘러 싸는 안전커버의 형상에 의하여 안전커버 내에 축적시키지 않고 배출하는 것을 특징으로 하는 것이다.In order to achieve the above object, the present invention, as a basic means, to discharge the cutting residues generated when grooving the workpiece by the side cutter without accumulating in the safety cover by the shape of the safety cover surrounding the side cutter. It is characterized by.

본 발명의 일 실시예를 도 1 내지 도 3에 의하여 설명한다. 커터(20)는 2개의 부재의 맞댐부의 2개의 부재(11, 12)를 절삭하여 맞댐부에 홈(13)을 설치한다. 23은 2개의 부재의 맞댐부의 중심위치에 커터(20)를 유도하는 광학센서이다. 21은 커터의 주위를 덮는 커버이다. 절삭 찌꺼기는 커버(21) 내로도 유도되어 축적된 다. 31은 홈(13) 내에 충전되는 충전재이다. 32는 충전재(31)를 홈(13)으로 유도하는 롤러이다. 33은 홈(13)으로부터 충전재가 마찰교반접합에 의하여 튀어 나오는 것을 방지하는 가압롤러이다. 41은 마찰교반접합공구이다. 상기 부재(11, 12)와 충전재(13)의 3자를 마찰교반접합한다. 24는 마찰교반접합공구(41)를 충전재(31)의 중심으로 유도하는 광학센서이다. 51은 에어분출노즐이고, 커터 (20)의 근방을 경유하여 홈을 향하여 분출한다. 52는 에어분출노즐이고, 커버의 후부에 있으며, 홈(13)을 향하여 에어를 분출한다.An embodiment of the present invention will be described with reference to FIGS. The cutter 20 cuts the two members 11 and 12 in the butt part of the two members, and provides the groove 13 in the butt part. 23 is an optical sensor which guides the cutter 20 to the center position of the butt | matching part of two members. 21 is a cover covering the cutter. Cutting residues are also induced and accumulated in the cover 21. 31 is a filler filled in the groove 13. 32 is a roller for guiding the filler 31 into the groove 13. 33 is a pressure roller which prevents the filler from protruding from the groove 13 by friction stir welding. 41 is a friction stir welding tool. The three members of the members 11 and 12 and the filler 13 are subjected to friction stir welding. 24 denotes an optical sensor for guiding the friction stir welding tool 41 to the center of the filler 31. 51 is an air blowing nozzle, and blows toward a groove | channel through the cutter 20 vicinity. Denoted at 52 is an air blowing nozzle, located at the rear of the cover, to blow air toward the groove 13.

이와 같은 구성에 있어서, 맞댐부를 커터(20)로 절삭하고, 맞댐부의 간극을 일정하게 하여 충전재를 삽입하고, 회전공구(41)로 마찰교반접합한다. 커터(20)로 절삭한 경우, 그 절삭 찌꺼기는 분출노즐(51)의 에어로 불어 날린다. 커터(20)에 부착된 절삭 찌꺼기는 불어 날려져 커버 내에 축적되지 않는다. 또 홈(13) 내에 남은 절삭 찌꺼기는 분출노즐(52)의 에어로, 홈(13) 밖으로 불어 날려진다. 이 때문에 절삭을 계속해서 할 수 있고, 또 홈(13) 내에 충전재(31)를 확실하게 삽입할 수 있어 마찰교반접합을 할 수 있다.In such a configuration, the butt portion is cut by the cutter 20, the gap between the butt portions is fixed, a filler is inserted, and the friction stir welding is performed by the rotary tool 41. In the case of cutting with the cutter 20, the cutting dregs are blown off by the air of the jet nozzle 51. The cutting debris attached to the cutter 20 is blown off and does not accumulate in the cover. In addition, the cutting residue remaining in the groove 13 is blown out of the groove 13 by the air of the jet nozzle 52. For this reason, cutting can be continued, the filler 31 can be inserted reliably in the groove | channel 13, and friction stir welding can be performed.

도 2, 도 3에 있어서, 커버(10)의 전단측의 에어분출노즐(51)의 주변은 원호형상으로 되어 있다. 이 때문에 커터(20)의 회전방향을 따라 절삭 찌꺼기를 순회시킨다. 이에 의하여 홈(13)측을 향하여 절삭 찌꺼기는 흐르고, 부재와 커버(21)의 간극으로부터 절삭 찌꺼기는 배출된다.2 and 3, the periphery of the air blowing nozzle 51 on the front end side of the cover 10 is in the shape of an arc. For this reason, cutting chips are circulated along the rotational direction of the cutter 20. As a result, the cutting dregs flow toward the groove 13 side, and the cutting dregs are discharged from the gap between the member and the cover 21.

부재(11, 12)는 수평방향을 따르고 있고, 맞댐부의 위쪽에 커터(20), 및 커버(21)가 있다. 이 때문에 커버(21)의 하단 및 홈(13)은 아래쪽에 있고, 커버(21) 의 하단은 개구되어 있다.The members 11 and 12 are in the horizontal direction, and the cutter 20 and the cover 21 are located above the butt portion. For this reason, the lower end of the cover 21 and the groove 13 are below, and the lower end of the cover 21 is open.

도 4의 실시예는 에어분출노즐(51) 대신에 커터(20)의 회전축에 프로펠러(60)를 설치하고, 커터(20)와 함께 회전시켜 분출하여 공기를 얻어 절삭 찌꺼기를 배출시키는 것이다.4, the propeller 60 is installed on the rotating shaft of the cutter 20 instead of the air blowing nozzle 51, and rotates together with the cutter 20 to eject and obtain air to discharge the cutting dregs.

본 발명에 의하면, 홈 가공시에 발생하는 절삭 찌꺼기를 효율좋게 제거함으로써, 홈 내에 충전재를 확실하게 삽입할 수 있어 접합불량을 방지할 수 있다.According to the present invention, by efficiently removing the cutting debris generated during the groove processing, the filler can be reliably inserted into the groove, thereby preventing the bonding failure.
