이단 행정 실린더{DOUBLE STROKE CYLINDER}Double Stroke Cylinder {DOUBLE STROKE CYLINDER}

도 1은 본 고안의 실시예에 따른 이단 행정 실린더의 스토퍼가 실린더 본체의 내주면으로 돌출된 상태를 도시한 단면도, 및1 is a cross-sectional view showing a state in which a stopper of a two-stroke cylinder according to an embodiment of the present invention protrudes into an inner circumferential surface of a cylinder body; and

도 2는 본 고안의 실시예에 따른 이단 행정 실린더의 스토퍼가 실린더 본체의 내주면으로부터 함몰된 상태를 도시한 단면도이다.Figure 2 is a cross-sectional view showing a state in which the stopper of the two-stroke cylinder according to the embodiment of the present invention is recessed from the inner peripheral surface of the cylinder body.

본 고안은 이단 행정 실린더 관한 것으로, 더욱 상세하게는, 이단으로 행정을 할 수 있도록 구성된 이단 행정 실린더에 관한 것이다.The present invention relates to a two-stage stroke cylinder, and more particularly, to a two-stage stroke cylinder configured to enable two-stage stroke.

일반적으로, 이단 행정 실린더는 대상물을 2개의 거리로 이동시켜야 하는 것이 필요한 경우에 2개의 행정으로 작동할 수 있도록 구성된 것이다.Generally, two-stroke cylinders are configured to operate in two strokes where it is necessary to move the object two distances.

종래에는 하나의 실린더의 후단에 다른 하나의 실린더의 피스톤 로드를 연결하여, 짧은 거리의 행정이 필요한 경우에는 하나의 실린더만을 작동시키고, 긴 거리의 행정이 필요한 경우에는 2개의 실린더들을 모두 작동시켰다.Conventionally, a piston rod of another cylinder is connected to the rear end of one cylinder, so that only one cylinder is operated when a short distance stroke is required, and both cylinders are operated when a long distance stroke is required.

그러나 이러한 종래의 이단 행정 실린더는 2개의 실린더를 연결한 것이므로 부피가 클 뿐만 아니라 각각의 실린더에 공압 또는 유압을 공급해야 하므로 구조가 복잡하다는 문제가 있다.However, such a conventional two-stroke cylinder is connected to two cylinders, so that the structure is complicated because it is not only bulky but also needs to supply air pressure or hydraulic pressure to each cylinder.

본 고안은 이러한 종래의 문제점을 해결하기 위한 것으로, 부피가 작으면서도 간단한 구조로 이단 행정을 할 수 있도록 구성된 이단 행정 실린더를 제공하는 데에 그 목적이 있다.The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a two-stage stroke cylinder configured to perform a two-stage stroke with a simple structure with a small volume.

상기한 바와 같은 목적 달성을 위하여, 본 고안에 의한 이단 행정 실린더는, 내부에 피스톤 및 피스톤 로드가 왕복 가능하게 삽입된 실린더 본체와, 상기 실린더 본체의 내주면의 중간에 출몰 가능하게 설치되는 적어도 하나의 스토퍼를 포함하는 구성으로 되어 있다.In order to achieve the object as described above, the two-stroke cylinder according to the present invention, the cylinder body with the piston and the piston rod is reciprocally inserted therein, and at least one installed in the middle of the inner circumferential surface of the cylinder body It is the structure containing a stopper.

이하, 본 고안의 실시의 형태를 실시예에 근거하여 도면을 참조하면서 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described, referring drawings for an Example.

도 1 및 도 2에는 본 고안의 실시예에 따른 이단 행정 실린더가 예시되어 있다. 이단 행정 실린더는 실린더 본체(10)와 피스톤(20)과 스토퍼(40)로 구성되어 있다.1 and 2 illustrate a two-stroke cylinder according to an embodiment of the present invention. The two-stroke cylinder is composed of a cylinder body 10, a piston 20, and a stopper 40.

실린더 본체(10)의 내부에는 피스톤(20)이 왕복 가능하게 삽입되어 있다.The piston 20 is inserted in the cylinder main body 10 so as to reciprocate.

피스톤(20)의 일단에는 피스톤 로드(21)가 연결되어 있다. 본 실시예에서는 피스톤 로드(21)의 피스톤(20)의 일단에만 형성된 것으로 예시하였지만, 피스톤 로드는 피스톤의 양단 모두에 형성될 수도 있음을 알 수 있을 것이다.The piston rod 21 is connected to one end of the piston 20. In the present embodiment has been illustrated as being formed only at one end of the piston 20 of the piston rod 21, it will be appreciated that the piston rod may be formed at both ends of the piston.

실린더 본체(10)의 양단에는 이를 통해서 공압 또는 유압이 유입되거나 유출 되게 하는 포트(11, 13)가 형성되어 있다. 포트(11)를 통해 공압 또는 유압이 유입되고 포트(13)를 통해 공압 또는 유압이 유출되면 피스톤(20)이 도면에서 우측으로 이동하고, 포트(13)를 통해 공압 또는 유압이 유입되고 포트(11)를 통해 공압 또는 유압이 유출되면 피스톤(20)이 도면에서 좌측으로 이동하게 된다.Ports 11 and 13 are formed at both ends of the cylinder body 10 to allow pneumatic or hydraulic pressure to flow in or out. When pneumatic or hydraulic pressure flows in through the port 11 and pneumatic or hydraulic pressure flows out through the port 13, the piston 20 moves to the right side in the drawing, and the pneumatic or hydraulic pressure flows in through the port 13 and the port ( When pneumatic or hydraulic pressure is leaked through 11), the piston 20 moves to the left in the drawing.

이 실린더 본체(10)의 내주면의 중간에는 적어도 하나의 스토퍼(40)가 출몰 가능하게 설치되어 있다. 본 실시예에서는 2개의 스토퍼(40)가 대칭되게 설치된 것으로 예시하였으나, 1개의 스토퍼(40)가 설치되는 것도 가능하고, 3개 이상의 스토퍼(40)가 균일한 간격으로 설치되는 것도 가능하다.At least one stopper 40 is provided in the middle of the inner circumferential surface of the cylinder main body 10 so that it can be projected. In the present embodiment, two stoppers 40 are symmetrically installed, but one stopper 40 may be installed, and three or more stoppers 40 may be installed at uniform intervals.

이 스토퍼(40)는 원통체로서 실린더 본체(10)의 중간에 그 외측으로 돌출되게 형성된 적어도 하나의 부시(15) 내에 밀봉적으로 삽입되어 안내되면서 실린더 본체(10)의 내주면으로 출몰된다. 스토퍼(40)가 부시(15) 내에서 밀봉적으로 삽입되어 안내되게 하는 수단으로서는 원통체인 스토퍼(40)의 외주면에 피스톤 링 등을 들 수 있다. 이러한 밀봉 안내 수단은 공지의 기술이므로 도면에 상세하게 도시하지 않았다.The stopper 40 is a cylindrical body, and is inserted into and guided in at least one bush 15 formed to protrude outwardly in the middle of the cylinder body 10, and emerges to the inner circumferential surface of the cylinder body 10. As means for allowing the stopper 40 to be sealedly inserted and guided in the bush 15, a piston ring or the like may be mentioned on the outer circumferential surface of the stopper 40, which is a cylindrical body. Since the seal guide means is a known technique, it is not shown in detail in the drawings.

부시(15)의 말단에는 전자식 또는 수동으로 작동되는 액추에이터(30)가 설치되어 있다. 액추에이터(30)는 실린더 본체(10)의 반경방향 바깥쪽의 스토퍼(40)의 일단에 연결되어 스토퍼(40)를 왕복시켜서 스토퍼(40)가 실린더 본체(10)의 내주면으로 출몰되게 한다.At the end of the bush 15, an actuator 30 which is electronically or manually operated is provided. The actuator 30 is connected to one end of the stopper 40 in the radially outer side of the cylinder body 10 to reciprocate the stopper 40 so that the stopper 40 emerges to the inner circumferential surface of the cylinder body 10.

액추에이터(30)에는 도시하지는 않았지만 제어부가 연결될 수 있으며, 이 제어부는 액추에이터의 작동을 제어한다.Although not shown, the actuator 30 may be connected to a control unit, and the control unit controls the operation of the actuator.

이러한 구성에 의한 본 고안의 이단 행정 실린더의 작동을 설명하면 다음과 같다.Referring to the operation of the two-stroke cylinder of the present invention by such a configuration as follows.

먼저, 도 1에서는 액추에이터(30)가 스토퍼(40)를 실린더 본체(10)의 내주면으로 돌출되게 작동시킨 상태를 도시하고 있다. 이 상태에서는 피스톤(20)이 짧은 거리의 행정으로 이동하게 된다.First, FIG. 1 shows a state in which the actuator 30 is operated to protrude the stopper 40 to the inner circumferential surface of the cylinder body 10. In this state, the piston 20 moves in a short distance stroke.

다음, 도 2에서는 액추에이터(30)가 스토퍼(40)를 실린더 본체(10)의 내주면으로부터 함몰되게 작동시킨 상태를 도시하고 있다. 이 상태에서는 피스톤(20)이 긴 거리의 행정으로 이동하게 된다.Next, FIG. 2 shows a state in which the actuator 30 is operated by recessing the stopper 40 from the inner circumferential surface of the cylinder body 10. In this state, the piston 20 moves in a long distance stroke.

전술한 본 고안의 이단 행정 실린더에 의하면, 종래의 이단 행정 실린더와 달리, 2개의 실린더를 연결하지 않고 단지 실린더 본체의 내주면 중간에 스토퍼를 출몰 가능하게 설치하므로, 부피가 작으면서도 간단한 구조로 이단 행정을 할 수 있는 효과가 있다.According to the two-stroke cylinder of the present invention described above, unlike the conventional two-stroke cylinder, the stopper is installed in the middle of the inner circumferential surface of the cylinder body without connecting the two cylinders, so that the two-stroke is small and simple in structure. There is an effect that can be done.
