본 고안은 소형수직머시닝센타의 도어 개폐장치에 관한 것으로 특히 자동으로 도어를 개폐하지않고 수동조작에 의해 개폐되도록한 것이다.The present invention relates to a door opening and closing device of a small vertical machining center, in particular to be opened and closed by manual operation without opening and closing the door automatically.

소형수직 머시닝센타에서 종래의 도어개폐장치는 실린더에 의해 자동으로 개폐되는 자동도어를 체택하였기 때문에 그 장치에 필요한 실린더, 체인, 밸브, 베어링, 가이드등 각종 고가의 부품이 부가되어 가격이 상승하므로 채택이 불가능한 문제점이 있을뿐만 아니라 그 외에도 도어가 수직 또는 수평으로 열렸을시 내부에서 가공물이 가공되는 중에 절삭유와 칩이 외부로 비산되는 등의 문제점이 있었다.In the small vertical machining center, the conventional door opening and closing device adopts an automatic door that is automatically opened and closed by a cylinder, so that various expensive parts such as cylinders, chains, valves, bearings, guides, etc. required for the device are added, so that the price increases. In addition to this impossible problem, when the door is opened vertically or horizontally, there was a problem such that cutting oil and chips were scattered to the outside while the workpiece was being processed.

따라서, 본 고안은 이와같은 종래의 제반 문제점을 해소하고자 수동조작으로 도어를 간편하게 작동시켜 개폐할수 있도록 하였으며 특히 가공율을 가공중인 테이블측과 가공물을 착탈하는 테이블축을 완전히 분리시키기 위하여 도어가 열렸을 때 두 테이블면을 분리시키는 역할을 하도록 하므로서 절삭유나 칩이 외부로 비산되는 것을 방지할 수 있도록한 것으로 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Therefore, the present invention allows the door to be easily opened and closed by manual operation in order to solve the above conventional problems. Especially, when the door is opened to completely separate the table shaft that removes the workpiece from the table side being processed, It will be described in detail by the accompanying drawings to prevent the cutting oil or chips from being scattered to the outside by acting to separate the table surface as follows.

수직형 머시닝센터의 도어(2) 내측상단에 양측으로 상단 링크(3)(4)를 유착하여 힌지붕(5)에 고정하고 힌지붕(5)의 양단은 본체(1)에 고정된 두개의 지지구(6)(7)에 유착되도록하고 일측 외단에는 리미트스위치(8)과 접면된 연결간(9)을 고정하며, 연결간(9)과 본체(1) 사이에 연결한 인장스프링(10)에 의해 하방으로 인장력을 갖도록 하고, 도어(2)의 하부 양측면은 내축으로 절곡된 걸림턱(11)을 갖도록 하고 하단링크(12)(13)를 그 절곡된 양측면과 본체(1)에 고정된 브라켓트(14)(15)사이에 유착하여서 된 것이다.The upper link (3) (4) is fixed to the hinge roof (5) by attaching the upper link (3) (4) to both sides on the inner top of the door (2) of the vertical machining center, and both ends of the hinge roof (5) are fixed to the main body (1) The tension spring (10) is attached to the support (6) (7) and fixed to the outer end of the connection between the limit switch (8) and the connecting end (9) between the connecting rod (9) and the main body (1) The lower side of the door (2) has a locking jaw (11) bent to the inner shaft and the lower link (12) (13) to the bent both sides and the body (1) It is due to the adhesion between the bracket (14) (15).

도면중 미설명부호 2a는 도어 손잡이 이다.In the figure, reference numeral 2a denotes a door handle.

이와같은 본 고안은 제2도와 제7도 및 제8도와같이 도어(2)가 닫힌상태에서 도어손잡이(2a)를 앞으로 당기면 제7도에서의 화살표로 표시된 궤도를 따라 제2도와 제4도 및 제12도에서 나타난 바와 같이 완전히 열리게 되는 것이다.The present invention, as shown in FIGS. 2 and 7 and 8, when the door handle 2a is pulled forward while the door 2 is closed, the second and fourth views along the track indicated by the arrow in FIG. As shown in Figure 12, it is fully open.

이를 더욱 구체적으로 설명하면 제8도와 같은 상태에서 도어(2)를 약간 당기면 도어(2)는 스프링(10)의 탄성에 의해 상단 링크 (3)(4)와 하단링크(12) (13)의 각 지점(A)(B)을 중심으로 상향회전 운동되어 제9도와 같이 궤도를 따라 움직이게 된다.In more detail, when the door 2 is slightly pulled in the state shown in FIG. 8, the door 2 is formed by the elasticity of the spring 10 and thus the upper link 3, 4 and the lower link 12, 13. Each of the points (A) and (B) is rotated upward to move along the track as shown in FIG.

이때, 스프링(10)은 연결간(9)을 하측으로 당기게되므로 힌지붕(5)이 지점(A)을 중심으로 회전하게되고 회전되는 힌지붕(5)에 의해 상부 링크(3)(4)가 상향 회전되어 도어(2)를 들어올리게 되는 것이다.At this time, the spring 10 is pulled down between the connection (9) so that the hinge roof (5) is rotated about the point (A) and the upper link (3) (4) by the hinge roof (5) is rotated Is to be rotated upward to lift the door (2).

계속되는 스프링(10)의 당기는 힘에 의해 도어(2)는 제10도와 같이 상승하게 되고 제11도에서 보는 바와같이 도어(2)가 상승완료하면 하단 링크(12)(13)가 그 회전 중심인 지점(B)을 넘어서게 되므로 도어(2)가 자체 중량으로 다시 하강되게 시작한다.By the pulling force of the spring 10, the door 2 is raised as shown in FIG. 10, and as shown in FIG. 11, when the door 2 is completed, the lower links 12 and 13 are the centers of rotation thereof. Beyond the point B, the door 2 starts to lower back to its own weight.

이때 상단링크(3)(4)는 그 지점(A)의 상사점을 넘지 못한 상태에서 문이 하강하므로 역회전을 시작하며, 스프링(10)은 계속 연결간(9)을 당기고 있기 때문에 하강하는 도어(2)의 무게를 받치게 되어서 도어(2)의 급격한 운동을 막게되며, 도어(2)의 걸림턱(11)이 하부링크(12)(13)에 가해지는 급격한 충격하중을 상쇄시키게되는 것이다.At this time, the upper link (3) (4) starts the reverse rotation because the door is lowered in the state not exceeding the top dead center of the point (A), spring 10 continues to pull down because the connection (9) is pulling By supporting the weight of the door (2) to prevent the sudden movement of the door (2), the locking jaw (11) of the door (2) to cancel the sudden impact load applied to the lower link (12, 13) will be.

상단 링크(3)(4)가 역회전하면 도어(2)는 제12도에서 보는 것과 같이 하단의 공작물(16) 윗부분에서 간섭을 일으키지 않고 본제(1) 내측으로 수평이동을 하여 도어(2)의 양측 걸림턱(11)이 하부링크(12)(13)에 걸려지는 순간 걸림턱(11)이 스톱퍼 역할을 하게되어 정지하게 되는 것이다.When the upper link (3) (4) is rotated in reverse, the door (2) is horizontally moved into the main body (1) without causing interference in the upper part of the workpiece 16 as shown in FIG. At the moment when both sides of the locking jaw 11 is caught by the lower link (12) 13, the locking jaw 11 serves as a stopper to stop.

이때, 도어(2)는 가공되어져 교체하기위한 공작물(16)과 가공중에 있는 공작물(17)사이의 턴테이블(18)중심위치에 멈추게되므로서, 가공중에 있는 공작물에서 비산되는 절삭유나 가공칩이 착탈측에서 공작물(16)을 착탈하고 있는 작업자에게 튀어오게되는 것을 방지하게되는 것이다.At this time, the door 2 is processed and stopped at the center position of the turntable 18 between the workpiece 16 to be replaced and the workpiece 17 being processed, so that cutting oil or cutting chips scattered from the workpiece under processing are removed. It will be prevented from jumping to the worker detaching the workpiece 16 from the side.

또한, 리미트 스위치(8)는 도어(2)가 열릴때, 힌지붕(5)에 고정된 연결된(9)이 작동시키게 되는데 이는 도어(2)의 개폐를 확인하는 스위치로서 도어(2)가 열려있는 상태에서는 어떠한 경우에도 회전테이를(18)이 회전되지 못하도록 제어하게된다.In addition, when the door 2 is opened, the limit switch 8 operates the connected 9 fixed to the hinge roof 5, which is a switch confirming the opening and closing of the door 2. In any state, the rotating tape 18 is controlled to prevent the rotation.

이와같이 열린도어(2)를 닫고자할시는 도어의 손잡이(2a)를 잡고 전방으로 당기면 전술한 반대의 작용으로 도어(2)는 원위치 되면서 닫히게 되는 것이다.When the door 2 is to be closed in this manner, the door 2 is closed while being returned to its original position by holding the handle 2a of the door and pulling it forward.

이와같이 된 본 고안의 종래와 같이 실린더에의해 개폐되는 자동도어를 사용하므로서 각종고가의 부품이 필요하게되어 원가가 상승되고, 가공물을 가공중에 절삭유와 칩이 외부로 비산되던것을 수동으로 간편하게 도어를 개폐할수 있도록 하므로서 보다 저렴한 가격으로 도어를 실치할수 있을 뿐아니라 가공물에 간섭을 일으키지 않고 내측으로 열리어 가공중에 비산되는 절삭유와 칩을 도어가 막아주게되므로 도어개폐공간을 필요로하지 않는 장점과 함께 작업의 능률을 향상시키게되는 유용한 고안인 것이다.By using the automatic door that is opened and closed by the cylinder as in the prior art of the present invention as described above, various expensive parts are required and the cost is increased, and the door can be easily opened and closed manually while cutting oil and chips are scattered to the outside during processing the workpiece. This allows the door to be installed at a lower price, and does not interfere with the workpiece. The door prevents cutting oil and chips from being scattered during processing, which does not require door opening and closing space. It is a useful design to improve efficiency.
