이하 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안에 따른 록킹실린더는, 실린더몸체(10)와, 상기 실린더몸체(10)에 축방향으로 슬라이드이동가능하게 설치되는 실린더로드(40)와, 상기 실린더몸체(10)의 내부에 축방향을 중심으로 회전가능하게 삽입설치되고 상기 실린더로드(40)와 볼트결합하는 스크류봉(50) 및, 상기 스크류봉(50)의 일측에 고정결합되는 라체트기어(60), 상기 라체트기어(60)를 정지시키는 라체트(70)를 포함한다.Locking cylinder according to the present invention, the cylinder body 10, the cylinder rod 40 which is slidably axially installed on the cylinder body 10, and the axial direction in the interior of the cylinder body (10) The screw rod 50 is rotatably inserted into the center and bolted to the cylinder rod 40, and the ratchet gear 60 fixed to one side of the screw rod 50 and the ratchet gear 60. ) And a ratchet 70 to stop.

상기 실린더몸체(10)는 내부에 중공이 형성되고, 일단에 유압라인이 연결되는 록킹블럭(20)이 고정결합되며, 그 록킹블럭(20)의 후단에 중공의 일측을 개폐하는 마개부(30)가 결합된다.The cylinder body 10 has a hollow formed therein, the locking block 20 is fixedly coupled to one end of the hydraulic line is connected, the stopper 30 for opening and closing one side of the hollow on the rear end of the locking block 20 ) Are combined.

상기 록킹블럭(20)은 상기 실린더몸체(10)의 중공으로 유체를 출입시키는 유로가 형성되고, 일측에 스크류봉 수용홈(21)이 형성되며, 그 스크류봉 수용홈(21)과 연통하여 라체트 수용홈(22)이 형성되고, 그 라체트 수용홈(22)과 연통하여 공기유로(23)가 형성되어 있다.The locking block 20 is formed with a flow path for entering the fluid into the hollow of the cylinder body 10, the screw rod receiving groove 21 is formed on one side, and communicate with the screw rod receiving groove 21 The check receiving groove 22 is formed, and the air passage 23 is formed in communication with the ratchet receiving groove 22.

상기 마개부(30)는 상기 실린더로드(40)가 록킹블럭(20)을 관통하여 상기 실린더몸체(10)의 내부에 삽입된 상태에서 실린더몸체(10)의 후단을 밀봉하게 되고, 그 일단에 힌지부(31)가 형성되어 있다.The stopper 30 seals the rear end of the cylinder body 10 in a state where the cylinder rod 40 penetrates the locking block 20 and is inserted into the cylinder body 10, and at one end thereof. The hinge part 31 is formed.

상기 실린더로드(40)는 상기 실린더몸체(10)의 중공으로 슬라이드이동가능하게 삽입되고, 축방향을 따라 중공부(41)가 형성되며, 그 중공부(41)의 내부에 나사산으로 된 암나사부(42)가 형성되어 있다.The cylinder rod 40 is slidably inserted into the hollow of the cylinder body 10, the hollow portion 41 is formed along the axial direction, the female screw portion of the threaded portion in the hollow portion 41 (42) is formed.

상기 스크류봉(50)은 일측 외주면에 나사산으로 된 수나사부(51)가 축방향을 따라 형성되어 상기 실린더로드(40)의 암나사부(42)와 볼트결합하고, 상기 실린더몸체(10)의 내부에 축방향을 중심으로 회전가능하게 삽입설치되며, 후단에 라체트기어(60)가 결합되어 있다.The screw rod 50 has a male threaded portion 51 made of a screw thread on an outer circumferential surface of the screw rod 50 and bolted to the female threaded portion 42 of the cylinder rod 40, and the inside of the cylinder body 10. Is installed rotatably around the axial direction in the ratchet gear 60 is coupled to the rear end.

상기 스크류봉(50)은 축을 중심으로 회전가능하게 지지되되 축방향을 따라 이동하지 못하게 구속되고, 상기 실린더로드(40)는 축방향을 중심으로 회전하지 못하게 구속되나 축방향을 따라 이동가능하게 되어, 스크류봉(50)이 회전하게 되면 실린더로드(40)가 직선운동을 하게 되고, 실린더로드(40)가 축방향을 따라 직선운동을 하게 되면 스크류봉(50)이 회전하게 된다.The screw rod 50 is rotatably supported about an axis, but is constrained not to move along the axial direction, and the cylinder rod 40 is constrained not to rotate about the axial direction, but is movable along the axial direction. When the screw rod 50 is rotated, the cylinder rod 40 is linearly moved, and when the cylinder rod 40 is linearly moved along the axial direction, the screw rod 50 is rotated.

상기 스크류봉(50)은 다줄나사로 되어 실린더로드(40)가 이동하는 거리에 대한 회전속도가 일반나사에 비해 더 빠르므로 스크류봉(50)의 회전속도가 일정할 경우에는 실린더로드(40)의 이동속도를 현저하게 감속시킬 수 있게 된다.Since the screw rod 50 is a multi-threaded screw, the rotation speed of the distance that the cylinder rod 40 moves is faster than that of the general screw, so that when the rotation speed of the screw rod 50 is constant, the cylinder rod 40 The speed of movement can be significantly reduced.

상기 라체트기어(60)는 상기 스크류봉(50)의 일측에 고정결합되어스크류봉(50)과 일체로 회전하게 되고, 라체트(70)에 의해 구속된다.The ratchet gear 60 is fixedly coupled to one side of the screw rod 50 to rotate integrally with the screw rod 50, it is constrained by the ratchet 70.

상기 라체트(70)는 상기 록킹블럭(20)의 라체트 수용홈(22)에 상하방향으로 슬라이등이동가능하게 삽입되어 설치되고, 탄성스프링(75)에 의해 탄성적으로 이동하게 되며, 하단부가 스크류봉 수용홈(21)으로 출몰하면서 라체트기어(60)를 구속하게 됨으로써 스크류봉(50)의 회전을 저지하게 된다.The ratchet 70 is installed to be inserted into the ratchet receiving groove 22 of the locking block 20 in a vertical direction so as to be able to move in an up-and-down direction. The ratchet 70 is elastically moved by an elastic spring 75, and a lower end portion thereof. By restraining the ratchet gear (60) while coming into the screw rod receiving groove (21) to prevent the rotation of the screw rod (50).

상기 라체트(70)는 상기 록킹블럭(20)의 공기유로(23)로 출입하는 공기압에 의해 상방으로 밀려 올라가게 되고 탄성스프링(75)에 의해 하방으로 이동하여 원위치하게 되고, 탄성스프링(75)과 공기의 출입에 의해 작동하게 되므로 신속하게 개폐동작을 할 수 있게 된다.The ratchet 70 is pushed upward by the air pressure entering and exiting the air flow path 23 of the locking block 20 and moved downward by the elastic spring 75 to be in the original position, and the elastic spring 75 ) By the in and out of the air can be opened and closed quickly.

따라서, 평상시에는 라체트(70)가 하방으로 이동된 상태가 되어 라체트기어(60)를 구속하게 됨으로써 실린더로드(40)를 정지시키게 되고, 상기 록킹블럭(20)의 공기유로(23)로 공기를 유입시켜 라체트기어(60)의 구속을 해제함으로써 실린더로드(40)를 이동시키게 되는 것이다.Therefore, the ratchet 70 is normally moved downward to restrain the ratchet gear 60 to stop the cylinder rod 40, and to the air flow path 23 of the locking block 20. The cylinder rod 40 is moved by introducing air to release the restraint of the ratchet gear 60.

상기 스크류봉(50)은 다줄나사로 되어 실린더로드(40)의 이동거리가 작더라도 스크류봉(50)의 회전반경이 크므로 라체트(70)에 의해 지지되는 라체트기어(60)의 톱니가 바뀌게 되어 실린더로드(40)를 소폭으로 이동시킨 상태에서도 정지시킬 수 있게 된다.The screw rod 50 is a multi-threaded screw, so even if the moving distance of the cylinder rod 40 is small, since the rotation radius of the screw rod 50 is large, the teeth of the ratchet gear 60 supported by the ratchet 70 are It is changed so that it can be stopped even in the state which moved the cylinder rod 40 slightly.

상기 실린더로드(40)는 상기 스크류봉(50)과 볼트결합되어 실린더로드(40)의 축방향으로 작용하는 힘을 스크류봉(50)의 암나사부(42)의 경사면에 작용시킴으로써 스크류봉(50)을 회전시키게 되고, 암나사부(42)와 수나사부(51)의 마찰에 의해실린더로드(40)의 이동속도를 감쇄시키게 된다.The cylinder rod 40 is bolted to the screw rod 50 so that the force acting in the axial direction of the cylinder rod 40 acts on the inclined surface of the female threaded portion 42 of the screw rod 50. ) Is rotated, and the moving speed of the cylinder rod 40 is attenuated by friction between the female threaded portion 42 and the male threaded portion 51.

따라서, 상기 실린더로드(40)가 실린더몸체(10)의 축방향으로 신속하게 이동하지는 못하지만 감속되어 이동함으로써 실린더로드(40)의 급격한 동작에 의해 실린더로드(40)의 선단에 연결된 타장치에 충격을 주지 않게 되며 실린더로드(40)의 이동거리를 정밀하게 제어할 수 있게 되는 것이다.Therefore, the cylinder rod 40 does not move quickly in the axial direction of the cylinder body 10 but is decelerated and moved to impact other devices connected to the front end of the cylinder rod 40 by the sudden movement of the cylinder rod 40. Will not give and will be able to precisely control the moving distance of the cylinder rod (40).

이상에서 설명한 바와 같이 본 고안에 따른 록킹실린더에 의하면, 실린더로드의 직선운동을 다줄나사의 회전운동으로 변환시켜 실린더로드의 이동속도를 감소시킴으로써 실린더로드의 이동에 의한 충격을 줄이고, 실린더로드의 이동폭을 정밀하게 제어할 수 있어 실린더로드를 임의의 위치에서 정지시킬 수 있는 효과가 있다.As described above, the locking cylinder according to the present invention reduces the impact caused by the movement of the cylinder rod by reducing the moving speed of the cylinder rod by converting the linear movement of the cylinder rod into the rotational movement of the multi-threaded screw, thereby reducing the movement of the cylinder rod. Since the width can be precisely controlled, the cylinder rod can be stopped at an arbitrary position.
