Description

곡면에서도 적용 가능한 안전 드릴 커버 {Safety Drill Cover Applicable to Curved Surfaces}Safety Drill Cover Applicable to Curved Surfaces}

본 고안은 곡면 사용 가능한 드릴 커버에 관한 것으로, 보다 상세하게는 드릴 비트 주위에 개별적으로 직선 운동을 하는 보호구조물들이 둘러싸도록 형성되어 있어 드릴을 사용함에 있어서 드릴링 작업물의 형상에 관련없이 드릴 비트를 외부와의 접촉으로부터 차단시켜 줌으로써 드릴 비트로 인한 안전사고발생의 확률을 줄여주는 기구에 관한 것이다.The present invention relates to a drill cover that can be used on a curved surface, and more specifically, protective structures that individually move linearly around the drill bit are formed to surround the drill bit, so that when using the drill, the drill bit can be removed regardless of the shape of the drilling work piece. It relates to a mechanism that reduces the probability of a safety accident caused by a drill bit by blocking it from contact with the drill bit.

일반적으로 드릴은 회전하는 회전축에 절삭공구를 고정하여 회전시킴으로써 작업물에 구멍을 형성시키는 장치이다. 이러한 드릴을 사용함에 있어서 특수한 드릴이 아닌 경우 고정시키지 않고 자유롭게 이동시키면서 작업을 하게 된다. 이 경우에 작업자가 주변의 상황이나 드릴의 회전력, 회전반력에 의해 드릴 사용에 있어서 계획했던 경로를 이탈하게 되는 경우 회전하던 그리고 작업 중이었다면 마찰열로 인해 가열된 드릴 비트에 신체가 접촉하여 사고가 유발될 수 있다는 문제점이 있다.In general, a drill is a device for forming a hole in a workpiece by rotating a cutting tool fixed to a rotating shaft. In using such a drill, if it is not a special drill, the work is performed while moving freely without fixing it. In this case, if the operator deviates from the planned route in using the drill due to the surrounding circumstances, the rotational force of the drill, or the rotational reaction force. There is a problem that it can be.

이에 기존의 드릴들을 보면, 몇몇의 드릴들은 보조 손잡이가 달려 있거나 지지대가 형성되어 있으나 지지하는 면적이 협소하여 보호의 역할은 수행하지 못하고 있다. 그 외에 드릴보조기구들을 살펴볼 경우 드릴 부산물을 모아주는 역할을 수행하기 위한 고무재질의 보조기구이거나, 탁상용 드릴 머신 비트의 주변을 감싸주는 통모양의 드릴보조기구만이 존재한다. 그 외 기존 안전 드릴 커버의 경우 평면에서 작업할 때는 유용하지만, 곡면의 작업물에서 드릴링을 시도할 때는 드릴 커버와 작업물이 맞닿는 부분이 현저히 적어지게 되어, 드릴 비트가 외부에 노출되는 면적이 넓어져 안전 커버로의 효율이 낮아진다.Therefore, looking at the existing drills, some drills have an auxiliary handle or a support is formed, but the supporting area is narrow and thus does not perform the role of protection. In addition, when looking at drill auxiliary devices, there is only a rubber auxiliary device to collect drill by-products or a barrel-shaped drill auxiliary device that wraps around the bench drill machine bit. In the case of other existing safety drill covers, it is useful when working on a flat surface, but when trying to drill on a curved workpiece, the contact area between the drill cover and the workpiece is significantly reduced. This reduces the efficiency of the safety cover

본 발명의 목적은, 드릴을 사용함에 있어서 작업물의 모양에 상관없이 드릴 비트 주변에 부착시킨 보조기구의 형상이 변화되도록 함으로써 드릴 비트가 외부에 노출이 되어 작업 중 예기치 않은 상황에 의해 드릴이 계획하지 않은 경로로 이동할 경우 드릴 비트로 인해 벌어지는 사고나 상해를 방지하려는 것이다.An object of the present invention is to change the shape of the auxiliary tool attached around the drill bit regardless of the shape of the work piece when using the drill, so that the drill bit is exposed to the outside and the drill is not planned due to unexpected situations during operation This is to prevent accidents or injuries caused by the drill bit if it moves along an unfamiliar path.

본 발명이 해결하고자 하는 과제는, 이상에서 언급한 과제로 제한되지 않으며, 언급되지 않은 또다른 기술적 과제들은 아래의 기재로부터 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 명확하게 이해될 수 있을 것이다.The problem to be solved by the present invention is not limited to the above-mentioned problems, and other technical problems not mentioned can be clearly understood by those of ordinary skill in the art to which the present invention belongs from the description below. There will be.

상기 목적을 달성하기 위해 본 고안은 안전 커버를 복수의 대로 분리하여 면에 따라 각각의 대들이 개별적으로 상하 운동하며, 개별적으로 탄성체를 구비하고 있어 초기 상태로 복원될 수 있도록 구성된다.In order to achieve the above object, the present invention is configured to separate the safety cover into a plurality of rods, and each stand individually moves up and down according to the surface, and is individually provided with an elastic body so that it can be restored to its initial state.

드릴 작업을 하고자 하는 작업물의 겉면의 모양에 관계없이 사람의 손과 드릴의 비트 사이의 접촉을 완벽하게 차단할 수 있도록 하여 드릴 사용자의 안전을 보장할 수 있다.Regardless of the shape of the surface of the workpiece to be drilled, it is possible to completely block the contact between the human hand and the drill bit, thereby ensuring the safety of the drill user.
