본 발명은 양축형 전동드릴에 관한 것으로, 더욱 상세하게는 드릴척을 전후방 양측에 설치하는 구조로 하여 두 가지의 공구를 양측의 드릴척에 각각 물려 놓고 신속하게 번갈아 사용할 수 있도록 한 양축형 전동드릴에 관한 것이다.The present invention relates to a two-axis power drill, and more particularly, to a two-axis power drill in which the drill chuck is installed on both sides of the front and rear, so that two tools can be alternately used by the drill chucks on both sides. will be.

일반적으로 전동드릴은 한쪽에만 드릴척이 있기 때문에 구멍을 뚫거나 나사를 조이거나 하는 서로 다른 작업을 병행할 때 매번 드릴과 스크류 비트를 교환하 여야 되는 불편함이 있을 뿐만 아니라 작업시간이 지연되는 문제점이 있었다.In general, since the electric drill has only one drill chuck, it is not only inconvenient to replace the drill and screw bit each time when drilling or screwing or performing different tasks at the same time. .

또, 공구교환이 불편하여 두 개의 전동드릴에 각기 다른 공구를 물려 놓고 공구 교환 없이 작업을 하는 경우도 있지만 이 경우 전동드릴을 두 개 준비하여야 되는 단점이 있으며, 사용하지 않는 다른 전동드릴은 바닥이나 선반에 놓고 작업하기 때문에 다른 전동드릴을 놓고 집는 과정이 번거로워 사용이 불편하기는 마찬가지였다.In addition, there is a disadvantage that tool change is inconvenient, so that different tools can be left on two drills without changing tools. In this case, two drills are required. Working on the lathe was not convenient because of the cumbersome process of laying other drills.

본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 하나의 전동드릴을 이용 두 가지 공구를 편리하게 사용할 수 있는 양축형 전동드릴을 제공함에 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide a two-axis power drill that can conveniently use two tools using a single power drill.

이러한 본 발명의 목적을 달성하기 위하여 전동드릴몸체에 내장되는 복수의 전동모터와, 전동모터로부터 동력을 전달받고, 전동드릴몸체의 전·후방측에 설치되는 복수의 드릴척과, 전동드릴몸체에 설치되는 손잡이와, 전동드릴몸체에 설치되어 전·후방측의 드릴척을 번갈아 감싸는 보호커버로 구성하여 양축형 전동드릴이 제공된다.In order to achieve the object of the present invention, a plurality of electric motors embedded in the electric drill body, a plurality of drill chucks which are supplied with power from the electric motor and are installed at the front and rear sides of the electric drill body, and are installed on the electric drill body. It is provided with a handle and a protective cover installed on the electric drill body to alternately wrap the front and rear drill chuck is provided with a dual-axis electric drill.

이하 본 발명에 따른 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도1 및 도2에 도시된 바와 같이 전동드릴몸체(20)에 내장되는 복수의 전동모터(30)(32)와, 전동모터(30)(32)로부터 동력을 전달받고 전동드릴몸체(20)의 전·후방측에 설치되는 복수의 드릴척(40)(42)과, 상기 전동드릴몸체(20)에 설치되는 손잡이(50)와, 전동드릴몸체(20)에 설치되어 전·후방측의 드릴척(40)(42)을 번갈아 감싸는 보호커버(60)로 구성하였다.As shown in FIGS. 1 and 2, a plurality of electric motors 30 and 32 embedded in the electric drill body 20 and electric motors 30 and 32 receive power from the electric drill body. 20, a plurality of drill chucks 40 and 42 provided at the front and rear sides, the handle 50 provided at the power drill body 20, and the front and rear sides provided at the power drill body 20. The drill chuck 40, 42 of the protective cover 60 was alternately wrapped.

상기 손잡이(50)의 전후 양측에는 스위치(52)(54)가 설치되며, 핀(56)에 의해 전동드릴몸체(20)와 클레비스(clevis)결합되어 전후방측으로 각도를 전환할 수 있도록 구성하였다.Switches 52 and 54 are installed at both front and rear sides of the handle 50, and are coupled to the drill drill body 20 and clevis by a pin 56 to switch angles in the front and rear sides. .

즉, 양측의 드릴척(40)(42)에 물린 공구인 드릴(70)과 스크류비트(72)의 사용을 어느 한쪽으로 전환할 때 손잡이(50)도 후방측으로 당겨 각도를 전환할 수 있도록 함으로써 손목을 보다 편하게 한 상태에서 사용하도록 하였으며, 두 개의 스위치(52)(54)는 복수 전동모터(30)(32)에 각각 접속하여 해당하는 스위치(52)(54)에 의해서만 접속된 전동모터(30)(32)가 구동되도록 하였다.That is, when switching the use of the drill 70 and the screw bit 72, which are tools bitten by the drill chucks 40 and 42 on both sides, to one side, the handle 50 can also be pulled to the rear to switch angles. The two switches 52 and 54 are connected to the plurality of electric motors 30 and 32, respectively, so that the electric motors 30 connected only by the corresponding switches 52 and 54 can be used. 32 is driven.

상기 보호커버(60)는 "C"자 형의 단면구조를 가지며, 그 좌우측 내측면에는 서로 평행한 슬라이드리브(62)(64)를 전후 길이방방향으로 형성하고, 전동드릴몸체(20)의 좌·우측면에는 슬라이드리브(62)(64)와 미끄럼결합하는 가이드홈(22)(24)을 형성하였으며, 보호커버(60)가 자유롭게 분리된 상태에서 슬라이드리브(62)(64)의 간격이 가이드홈(22)(24)의 간격보다 다소 작게 되도록 하여 보호커버(60)를 전동드릴몸체(20)에 결합하였을 때 탄성에 의해 슬라이드리브(62)(64)가 가이드홈(22)(24)에 밀착하도록 하였다.The protective cover 60 has a cross-sectional structure of "C" shape, the left and right inner surface of the slide ribs 62, 64 are formed parallel to each other in the longitudinal direction, and the electric drill body 20 On the left and right sides, guide grooves 22 and 24 are formed to slide with the slide ribs 62 and 64, and the gap between the slide ribs 62 and 64 in the state where the protective cover 60 is freely separated. Slide ribs 62 and 64 are guide grooves 22 and 24 by elasticity when the protective cover 60 is coupled to the electric drill body 20 by being smaller than the gap between the guide grooves 22 and 24. )).

이하 본 발명에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도1 및 도2에 도시된 바와 같이 양측 드릴척(40)(42)에 각각 드릴 (70)과 스크류비트(72)와 같은 서로 다른 공구를 물려 놓은 상태에서 예컨대, 스크류비트(72)를 사용하려는 경우 이 스크류비트(72)가 앞으로 위치되도록 전동드릴몸체(20)를 돌린 다음 보호커버(60)를 후방으로 당겨 사용하지 않는 드릴척(40)과 드릴(70)을 덮은 상태에서 손잡이(50)의 앞쪽에 위치된 스위치(54)를 손가락으로 당기게 되면, 전방에 위치된 전동모터(32)로만 전류가 공급되어 전방측 전동모터(32)와 드릴척(42) 및 스크류비트(72)가 회전된다.As shown in Figs. 1 and 2, for example, the screw bits 72 are held in two drill chucks 40 and 42 with different tools such as the drill 70 and the screw bits 72 respectively. If you want to use it, turn the drill body 20 so that this screw bit 72 is located forward, and then pull the protective cover 60 backward to cover the unused drill chuck 40 and the drill 70 and the handle 50 When the switch 54 located at the front of the panel is pulled with a finger, current is supplied only to the electric motor 32 positioned at the front, so that the front electric motor 32, the drill chuck 42, and the screw bit 72 rotate. do.

즉, 첨부도면 도1에서와 같이 드릴(70)이 물려 있는 드릴척(40)을 보호커버(60)로 덮고 스크류비트(72)가 물려 있는 드릴척(42)을 노출시킨 상태에서 우측에 도시된 스위치(54)를 누르게 되면, 도면 중 우측에 위치된 전동모터(32)와 드릴척(42)이 회전하여 스크류비트(72)를 사용할 수 있게 된다.That is, as shown in FIG. 1, the switch shown on the right side of the drill chuck 40 having the drill 70 is covered with the protective cover 60 and the drill chuck 42 having the screw bit 72 exposed is exposed. When the 54 is pressed, the electric motor 32 and the drill chuck 42 located on the right side of the figure rotate to enable the screw bit 72 to be used.

이때 보호커버(60)는 사용하지 않는 공구와 드릴척(40)(42)을 덮어서 작업자를 보호하게 되며, 보호커버(60)를 다시 반대방향으로 슬라이딩시키게 되면, 보호커버(60)의 내측에 형성된 슬라이드리브(62)(64)가 전동드릴몸체(20)에 형성되어 있는 가이드홈(22)(24)으로부터 미끄러지면서 보호커버(60)를 직선안내하게 된다.At this time, the protective cover 60 covers the unused tools and drill chucks 40 and 42 to protect the worker. When the protective cover 60 is slid in the opposite direction again, the protective cover 60 is formed inside the protective cover 60. The slide ribs 62 and 64 slide from the guide grooves 22 and 24 formed in the power drill body 20 to guide the protective cover 60 in a straight line.

또, 드릴(70)을 사용하려는 경우에는 이 드릴(70)가 앞으로 위치되도록 전동드릴몸체(20)를 돌린 다음 보호커버(60)를 후방으로 당겨 사용하지 않는 드릴척(42)과 스크류비트(72)을 덮은 상태에서 손잡이(50)의 앞쪽에 위치된 스위치(52)를 손가락으로 당기게 되면, 전방에 위치된 전동모터(30)로만 전류가 공급되어 전방측 전동모터(30)와 드릴척(40) 및 드릴(70)이 회전된다.In addition, when the drill 70 is to be used, turn the drill body 20 so that the drill 70 is positioned forward, and then pull the protective cover 60 backward so that the drill chuck 42 and the screw bit 72 are not used. When the switch 52 located at the front of the handle 50 is pulled with a finger in the state of covering the current, the current is supplied only to the electric motor 30 positioned in the front, so that the front electric motor 30 and the drill chuck 40 are positioned. And drill 70 is rotated.

한편, 전동드릴몸체(20)에 클레비스결합되어 있는 손잡이(50)를 후방으로 당 기게 되면, 손잡이(50)가 기울게 되므로 손목을 보다 편하게 한 상태에서 작업할 수 있게 된다.On the other hand, when pulling the handle 50 is clevis coupled to the electric drill body 20 to the rear, the handle 50 is inclined so that the wrist can work in a more comfortable state.

이상에서 설명한 바와 같은 본 발명은 드릴척이 전동드릴몸체의 양측에 설치되어 있기 때문에 두 가지 공구를 양쪽 드릴척에 각각 물려 놓게 되면, 드릴척으로부터 공구를 분리할 필요 없이 전동드릴몸체를 반전시키고 보호커버를 이동시키는 것에 의해 편리하게 양쪽 공구를 번갈아 사용할 수 있는 효과가 있다.In the present invention as described above, since the drill chuck is installed on both sides of the electric drill body, if two tools are seized on both drill chucks, the electric drill body is reversed and the protective cover is moved without having to remove the tool from the drill chuck. By making it effective, both tools can be used alternately.
