Description

전기 드릴용 육각 원터치 척.{Hexagonal one-touch chuck for electric drill}{Hexagonal one-touch chuck for electric drill}

본 발명은 육각 원터치 척에 관한 것으로 더욱더 상세하게는 전기 드릴에 손쉽게 탈부착하여 사용할 수 있도록 한 전기 드릴용 육각 원터치 척에 관한 것이다. The present invention relates to a hexagonal one-touch chuck, and more particularly, to a hexagonal one-touch chuck for an electric drill that can be easily attached to and detached from an electric drill.

산업 현장에서 진행되는 분해, 조립, 부착 및 천공의 공정 중에 전동 드라이버, 임팩트 드라이버, 전기 드릴 등의 전용공구가 사용되는데, 이 중에 전기 드릴은 천공 작업만을 위하여 사용되므로, 다양한 작업을 수행하기 위하여 일반적으로 널리 사용되는 것이 일반 전동 드라이버와, 임팩트 드라이버이다. In the process of disassembling, assembling, attaching and drilling in the industrial field, a dedicated tool such as an electric screwdriver, an impact screwdriver or an electric drill is used. Among them, the electric drill is used only for the drilling operation. Is widely used as a general electric driver and an impact driver.

보통 충전식 전동 드라이버는 전기적 힘으로 회전하는 체결구에 각종 드라이버나 드릴 비트, 또는 어댑터를 이용한 복스 알 등을 각각 장착하여, 나사를 조이고 풀거나, 구멍을 천공하거나, 육각 볼트(또는 너트)를 조이고 푸는데 사용된다.Usually, a rechargeable electric screwdriver is equipped with various screwdrivers, drill bits, or voxel knuckles using adapters, which are screwed and loosened, drilled holes, or tightened hexagon bolts (or nuts) It is used to solve.

선행기술로는 공개특허번호 10-2010-0060379 "전기 드릴용 탈착식 햄머 장치"(이하, 선행 기술 1이라 함)에서는 전기 드릴 및 충전식 드릴의 드릴척에 또 하나의 드릴척을 상,하 진동하면서 회전력을 제공하는 햄머방치가 탈부착하여 사용하는 것이다. 실용신안 공개번호 20-2016-0004502 "드릴척의 척핸들"(이하, 선행기술 2라고 함)에서는 척 핸들 교체시에 접촉면적이 두배로 되며 스패너 공구 처름 머리부와 손잡이부가 적절한 각도로 경사져 형성된 것으로 조작의 편리성과 토크의 강한 힘이 실리게 한 것이다.
Prior art No. 10-2010-0060379 entitled " detachable hammer device for electric drill "(hereafter referred to as prior art 1), a drill bit of an electric drill and a rechargeable drill is vibrated up and down, The hammer stand provided is detachable and used. In the "chuck handle of a drill chuck" (hereinafter referred to as "prior art 2"), the contact area is doubled at the time of chuck handle replacement, and the head of the spanner tool and the handle are inclined at appropriate angles The convenience of operation and the strong force of torque are brought about.

상기 선행기술 1인 경우, 전기 드릴의 척에 연장되어 드릴척을 상,하로 진동하여 회전력을 제공하는 목적은 있으나, 햄머용으로만 사용이 가능하며 일반적인 회전운동에는 사용할 수 없으며, 두 개의 척을 이용하여 사용하기에 회전력을 저감시키는 문제점이 생기게 된다.In the case of the prior art 1, it is intended to extend to the chuck of the electric drill and to vibrate the drill chuck up and down to provide a rotational force, but it can be used only for the hammer and can not be used for the general rotational movement. There is a problem that the rotational force is reduced for use.

또한, 선행기술 2인 경우, 드릴을 교체시에 척 핸들을 드릴에 체결한 후 드릴에 체결된 척 핸들을 드릴 척에 결합시켜 드릴의 회전 방향 전환스위치를 분리 위치로 설정하여 드릴을 작동시켜 드릴을 분리함에 따라 안전상 문제와 분리와 체결시 시간이 많이 소요되는 문제점이 생기게 된다.
In the prior art 2, when the drill is replaced, the chuck handle is fastened to the drill, and then the chuck handle fastened to the drill is coupled to the drill chuck to set the rotation direction changeover switch of the drill to the disengaged position, There is a problem in that it takes a lot of time for separation and fastening.

상기와 같은 구조로 이루어진 본 발명은 크게 본체(10)와 작동부(20)로 나누어진다.The present invention having the above-described structure is roughly divided into a main body 10 and an operating portion 20.

본체(10)는 전기드릴(100)에 구비된 전기드릴 숫나사부(101)와 드라이버 비트(30)와 연결하기 위하여, 본체(10)는 내경에 암나사부(12)가 구비되어 전기 드릴 숫나사부(101)와 고정되고 상기 암나사부(12) 타측에는 육각 절개부(13)가 형성되어 드라이버 비트(30)를 거치할 수 있도록 한 것이다.The main body 10 is provided with an internal thread 12 on its inner diameter so as to be connected to an electric drill male part 101 provided in the electric drill 100 and a driver bit 30, And a hexagonal cutout portion 13 is formed on the other side of the female threaded portion 12 so that the driver bit 30 can be mounted.

또한, 상기 암나사부(12) 외경에는 제 2 암나사부(10-1)가 구비되어 무두 렌지 볼트(11)를 이용하여 더욱더 견고히 전기드릴 숫나사부(101)를 고정할 있다.
The second female screw portion 10-1 is provided on the outer diameter of the female screw portion 12 so that the electric drill male screw portion 101 can be more firmly fixed by using the stud bolt 11.

상기 드라이버 비트(200)에는 등 간격으로 내입홈(201)이 구비되어 본체(10)와 고정시킬 수 있도록 한 것이며, 본체(10)와 드라이버 비트(30) 연결시에는 본체(10)의 외 주면에는 관통공(16)이 구비되어 고정구(17)이 거치되게 된다. 일 실시에는 고정구(17)가 돌출되어 드라이버 비트(200)에 형성된 내입홈(201)에 걸려 드라이버 비트(30)는 본체(10)에 고정하게 된다. The driver bit 200 is provided with an inner groove 201 at an equal interval so as to be fixed to the main body 10. When the main body 10 and the driver bit 30 are connected, A through hole 16 is provided to fix the fixing hole 17. In one embodiment, the fastener 17 is protruded to engage the inner groove 201 formed in the driver bit 200 to fix the driver bit 30 to the main body 10.

또한, 상기 드라이버 비트(200)를 효율적으로 탈부착하기 위하여 본체(10) 외경에 구비된 걸림턱(18)에 탄성 부재(30)가 거치 되고 탄성 부재(30)외경에는 작동부(20)가 구비된다. 상기 탄성 부재(30)는 작동부(20)에 구비된 제 1 걸림부(21)에 걸리게 된다. In order to efficiently detach and attach the driver bit 200, an elastic member 30 is mounted on a locking protrusion 18 provided on an outer diameter of the main body 10, and an operation portion 20 is provided on an outer diameter of the elastic member 30 do. The elastic member 30 is caught by the first engaging portion 21 of the actuating portion 20. [

즉, 상기 탄성 부재(30)는 본체(10)의 걸림턱(18)과 작동부(20)의 제 1 걸림턱(21) 사이에 거치 된다.
That is, the elastic member 30 is interposed between the latching jaws 18 of the main body 10 and the first latching jaws 21 of the actuating part 20.

상기 제 1 걸림턱(21) 전방에는 공간부(23)가 구비되고 공간부(23) 전방에는 제 2 걸림턱(22)가 구비되어 있으며, 상기 공간부(23)는 작동부(20)를 후방으로 밀게 되면 본체(10)에 형성된 관통공(16)과 연결됨에 따라 관통공(16)에 거치된 고정구(17)는 공간부(23)로 이동할 수 있게 된다. A space portion 23 is provided in front of the first latching jaw 21 and a second latching jaw 22 is provided in front of the space portion 23. The space portion 23 is provided with an operation portion 20 The fastener 17 mounted on the through hole 16 can be moved to the space portion 23 by being connected to the through hole 16 formed in the main body 10. [

즉, 상기 작동부(20)를 후방으로 밀게 되면 고정구(17)가 드라이버 비트 (200)에 구비된 내입홈(201)에 이탈되어 드라이버 비트(200)를 분리시킬 수 있게 한 것이다.
That is, when the actuating part 20 is pushed backward, the fastener 17 is released to the inner groove 201 provided in the driver bit 200, so that the driver bit 200 can be separated.

드라이버 비트(200)를 장착시에는 작동부(20)를 후방으로 밀게 되면 고정구(17)가 작동부(20)의 공간부(23)와 본체(10)의 관통공(16)에 자유로이 유동할 수 있게 이동할 수 있게 된 상태에서 본체(10)의 내경에 형성된 육각 절개부 (13)에 드라이버 비트(200)를 거치한 다음 작동부(20)를 후방으로 밀고 있던 힘을 멈추게 되면 수축된 탄성 부재(30)가 팽창하면서 작동부(20)의 제 1 걸림부(21)가 후방으로 이동하여 공간부(23)와 관통공(16)에 거치되어 있던 고정구(17)가 육각 절개부(13)의 중심 방향으로 이동하여 유각 절개부(13)에 거치되어 있던 드라이버 비트(200)의 내입홈(201)에 면접 되어 드라이버 비트(200)는 고정하게 된다.
When the operation bit 20 is pushed backward when the driver bit 200 is mounted, the fixture 17 freely flows into the space portion 23 of the operation portion 20 and the through hole 16 of the main body 10 When the driver bit 200 is mounted on the hexagonal cutout portion 13 formed in the inner diameter of the main body 10 and the force pushing the operating portion 20 backward is stopped, The first engaging portion 21 of the actuating portion 20 is moved rearward as the first engaging portion 30 expands and the fixture 17 mounted on the space portion 23 and the through hole 16 is moved to the hexagonal cut portion 13, So that the driver bit 200 is fixed to the inner groove 201 of the driver bit 200 which has been mounted on the ramshaft cutout portion 13.

상기 작동부(20)가 본체(10)에 이탈됨을 방지하기 위하여 본체(10)의 홈부(14)에 고정링(15)이 삽입되어 작동부(20)에 구비된 제 2 걸림부(22)에 걸려 작동부(20)가 본체(10)에 이탈되지 않도록 한 것이다.
A fixing ring 15 is inserted into the groove 14 of the main body 10 to prevent the operation part 20 from being detached from the main body 10 and the second engaging part 22 provided on the operating part 20, So that the operating portion 20 is not released to the main body 10.

또한, 상기 고정구(17)는 본체(10)의 육각 절개부(13)의 중심 방향으로 낙하되지 않게 하기 위하여, 관통공(16)의 하부에는 제 2 걸림턱(17-1)이 형성되어 있다.In order to prevent the fixture 17 from dropping in the direction of the center of the hexagonal cutout 13 of the main body 10, a second engaging protrusion 17-1 is formed below the through hole 16 .

본 발명은 상기와 같은 구조로 이루어져 있어 작동부(20)를 이용하여 손쉽게 드라이버 비트(200)를 착탈 할 수 있게 한 것이다. According to the present invention, the driver bit 200 can be easily attached and detached using the operation unit 20.
