본 고안은 멘드밀이나 밀링커터 및 드릴공구등을 고정시키는 드릴척(DRILL CHUCK)에 관한 것으로 공구를 조이는 조임이빨을 용이하게 이동시켜 공구를 견고하게 조일 수 있도록 함과 아울러 진동에 의하여 조임이빨의 조임력이 쉬 이완되는 것을 방지할 수 있도록 한 것이다.The present invention relates to a drill chuck for fixing a mandrel, a milling cutter, and a drill tool. The tightening tooth for tightening the tool can be easily moved to tighten the tool, and the tightening force of the tightening tooth due to vibration is provided. This is to prevent the relaxation.

종래의 드릴척은 조임이빨의 외면에는 나사를 형성하고 외통의 경사내면에는 나사를 형성하여 서로 나사맞춤시켜 공구를 조이거나 풀고자 할때에는 외통의 단부에 형성시킨 기어에 별도의 공구를 나사맞춤하여 큰 힘으로 외통을 회전시키게 된 구조로 된 것이기 때문에 작동시킴이 매우 힘들 뿐만 아니라 기어의 마모가 빨라 사용수명이 매우 짧았으며 또한 공구를 조이는 조임이빨의 조임력이 견고하지 못하여 공구가 쉬 흔들거리게 되는 결점이 있었다.Conventional drill chucks have a screw on the outer surface of the tightening teeth and a screw on the inclined inner surface of the outer cylinder so that they can be screwed together to tighten or loosen the tools. It is a structure that rotates the outer cylinder with force, so it is very difficult to operate, and the wear of the gear is very short, and the service life is very short. Also, the tightening force of the tightening teeth for tightening the tool is not strong, and the tool shakes easily. there was.

본 고안은 이와 같은 결점을 감안하여 조작이 용이하고 강한 조임력과 작동중 조임력이 쉬 이완되지 않는 드릴척을 안출하게 된 것인데 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention, in view of this drawback is easy to operate and a strong chuck and a drill chuck that does not loosen the tightening force during operation is devised to be described in detail by the accompanying drawings as follows.

몸체(1)의 구멍(1')에 작동관(2)를 베어링(3')(3")(3'")을 개재시켜 회전자재하게 끼워 설치한 하방에는 걸림턱(4')을 돌설한 지지판(4)의 나사봉(5)을 나사맞춤하고 안내홈(1")내로 조임이빨(6)을 끼워 조임이빨(6)의 걸림홈(6')이 걸림턱(4')에 걸려지게 하여 작동관(2)을 좌,우로 회전시킴에 따라 각 조임이빨(6)의 간격을 넓히거나 좁힐 수 있도록 하고, 몸체(1)의 하방에는 캡(7)과 외통(8)을 나사맞춤으로 고정하고 작동관(2)의 단부에는 핸들(9)을 고정시켜서 된 것이다.The locking jaw (4 ') is turned on the lower side where the operating tube (2) is inserted into the hole (1') of the body (1 ') through a bearing (3') (3 ") (3 '"). The screw rod 5 of the snow support plate 4 is screwed in and the tightening tooth 6 is inserted into the guide groove 1 "so that the catching groove 6 'of the tightening tooth 6 is caught by the catching jaw 4'. Rotating the operation tube (2) to the left and right so that the interval between each tightening tooth (6) can be widened or narrowed, and the cap (7) and the outer cylinder (8) is screwed under the body (1) By fixing the handle 9 to the end of the operating tube (2).

미설명 부호 10은 모우터축이고, 11은 공구이다. 이와 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Reference numeral 10 is a motor shaft, and 11 is a tool. Referring to the effect of the present invention made as follows.

조임이빨(6)에 공구(11)를 고정시키고자 할때는 핸들을 잡고 작동관(2)을 제2도의 점선방향으로 회전시키게 되면 공회전되는 작동관(2)과 나사맞춤된 나사봉(5)은 우측으로 이동함에 따라 조임이빨(6)도 우측으로 이동하여 각 조임이빨(6)의 간격은 넓혀지게 된다.When fixing the tool 11 to the tightening tooth 6, hold the handle and rotate the operating tube 2 in the dotted line direction of FIG. 2, and the threaded rod 5 fitted with the idle operating tube 2 is As it moves to the right, the tightening teeth 6 also move to the right, so that the spacing of each tightening tooth 6 is widened.

다음 각 조임이빨(6)의 사이에 공구(11)를 끼우고 작동관(2)을 제2도의 실선화살표 방향으로 돌리게 되면 나사봉(5)은 좌측으로 이동함에 의하여 각 조임이빨(6)은 공구(11)에 압착되어 서로 견고하게 고정된다.Next, when the tool 11 is inserted between each of the tightening teeth 6 and the operating tube 2 is turned in the direction of the solid arrow of FIG. 2, the screwing rod 5 moves to the left, so that each tightening tooth 6 is The tools 11 are pressed and firmly fixed to each other.

이상태로 모우터축(10)에 끼워 회전시에는 조임이빨(6)을 조이는 나사봉(5)의 이동방향은 모우터축(10)의 회전방향과 동일방향으로 회전되게 하였으므로 회전작동중에는 공구(11)를 조이는 조임이빨의 조임력은 더욱 좋게 됨으로 공구(11)와 조임이빨(6)의 조임상태가 이완될 염려가 없다.Since the moving direction of the screw rod 5 for tightening the tightening teeth 6 is rotated in the same direction as the rotation direction of the motor shaft 10 when it is inserted into the motor shaft 10 in this state, the tool 11 during rotation operation. Fastening force of the tightening teeth to tighten the tightening state of the tool 11 and the tightening teeth (6) there is no fear that the tightening state is relaxed.

그리고 공구(11)를 빼고자 할때는 공구(11)을 끼울때와 마찬가지로 작동관(2)을 제2도의 점선화살표 방향으로 회전하여 각 조임이빨(6)의 간격을 넓혀 간단히 분리시키면 된다.When the tool 11 is to be removed, the operating tube 2 is rotated in the direction of the dotted arrow of FIG. 2 as in the case where the tool 11 is inserted, and the separation of the tightening teeth 6 is simply widened.

이와 같은 본 고안은 비교적 간단한 구조로 공구(11)의 조임력을 향상시킴과 동시에 진동에 의하여 공구(11)와 조임이빨(6)이 서로 이완되는 것을 완벽하게 방지할 수 있는 효과가 있다.This invention has a relatively simple structure to improve the tightening force of the tool 11 and at the same time there is an effect that can be completely prevented from loosening the tool 11 and tightening teeth 6 by vibration.
