미설명부호 13은 호스연결몸통(15)을 밸브(11)에 결합할 때 냉각수 유출을 방지하기 위한 고무패킹이고, 26는 드릴(91)을 회전부재(30)의 드릴결합부(33)에 결합할 때 사용되는 와셔이다.Reference numeral 13 is a rubber packing for preventing the leakage of cooling water when the hose connecting body 15 is coupled to the valve 11, 26 is a drill 91 to the drill coupling portion 33 of the rotating member 30 It is a washer used when joining.

도 5는 본 발명의 드릴의 코어결합용 아답터(1)의 사용상태도이다.5 is a state diagram used in the core coupling adapter 1 of the drill of the present invention.

도 1 내지 도 5를 참조하여 본 발명의 드릴의 코어결합용 아답터(1)의 작동원리에 대해 설명하면 다음과 같다. Referring to the principle of operation of the core coupling adapter 1 of the drill of the present invention with reference to Figures 1 to 5 as follows.

먼저, 냉각수공급탱크(93)의 밸브(미도시) 개방하면 냉각수가 냉각수공급호스(92)를 통해 본 발명의 드릴의 코어결합용 아답터(1)에 유입된다.First, when the valve (not shown) of the cooling water supply tank 93 is opened, the cooling water is introduced into the core coupling adapter 1 of the drill of the present invention through the cooling water supply hose 92.

이때, 사용자에 의해 밸브손잡이(12)의 온(ON) 동작이 이루어지면 상기 냉각수는 호스연결몸통(15) 내의 필터(14)를 거쳐 이물질을 걸려내는 과정을 거친다. At this time, when the ON operation of the valve handle 12 is made by the user, the coolant goes through a process of catching foreign matter through the filter 14 in the hose connecting body 15.

또한, 드릴결합부(33)의 타측에 결합되는 드릴(91)이 동작하면 이 회전력에 의해 상기 필터(14)를 통과한 냉각수는 냉각수유입구(23)를 통해 하우징(20) 내로 유입되고, 다시 냉각수유입공(32)을 통해 회전부재(30)의 내부로 유입된다. 이때, 냉각수유입공(32)이 테이퍼지게 형성되어져 있어 냉각수의 유입은 보다 원활해진다.In addition, when the drill 91 coupled to the other side of the drill coupling unit 33 operates, the coolant passing through the filter 14 by the rotational force is introduced into the housing 20 through the coolant inlet 23, and again. It is introduced into the rotating member 30 through the cooling water inlet hole (32). At this time, the coolant inlet 32 is formed to be tapered so that the coolant flows more smoothly.

회전부재(30)의 일측은 개방되고 타측인 드릴결합부(33)는 폐쇄되어 있는 관계로, 상기 냉각수는 회전부재(30)의 일측으로 이동한다.One side of the rotating member 30 is open and the other side of the drill coupling portion 33 is closed, the coolant moves to one side of the rotating member (30).

상기 냉각수는 그 내경이 점차 좁아지는 코어(40)를 통과하게 되고, 이에 따라 그 유속은 점차 빨라지게 되고, 비트(50)를 통해 외부로 배출된다.The cooling water passes through the core 40 whose inner diameter is gradually narrowed, so that the flow rate is gradually increased and discharged to the outside through the bit 50.

상기 냉각수는 비트(50)에 의해 타일(94), 유리 또는 세라믹 등에서 발생되는 분진의 날림 현상을 가라앉혀줄 뿐만 아니라 천공부분의 청소작업을 수행하여 마찰력을 감소시켜준다.The cooling water not only reduces the blowing of dust generated in the tile 94, glass or ceramic by the bit 50, but also reduces the frictional force by performing the cleaning operation of the perforated portion.

이에 따라 천공작업능률이 향상하게 된다.Accordingly, the drilling work efficiency is improved.

상기와 같이, 본 발명의 바람직한 실시예를 참조하여 설명하였지만, 해당 기술 분야의 숙련된 당업자라면 하기의 특허청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다.As described above, with reference to the preferred embodiment of the present invention, those skilled in the art will be variously modified and modified within the scope of the present invention without departing from the spirit and scope of the present invention described in the claims below. It will be appreciated that it can be changed.
