본 발명은 공작기계 스플래쉬 가드의 회전문에 설치된 회전문 댐핑 장치에 관한 것으로, 특히 회전문의 무거운 자중에 따른 진동 방지와 함께 작업자의 안전 사고를 방지할 수 있도록 한 스플래쉬 가드의 회전문 댐핑 장치에 관한 것이다.The present invention relates to a revolving door damping device installed on a revolving door of a machine tool splash guard, and more particularly, to a revolving door damping device of a splash guard that prevents a worker's safety accident along with vibration prevention due to heavy weight of the revolving door.

공작기계 예로, 보링머신의 스플래쉬 가드는 공작물의 가공 시에 절삭유와 절삭칩의 비산 방지를 위하여 설치된다.For example, splash guards of boring machines are installed to prevent scattering of cutting oil and cutting chips during machining of workpieces.

종래, 도 1에서와 같이 스플래쉬 가드(1)는 절삭유와 절삭칩의 비산 방지를 위한 좌우측 팬스와 전면부에는 대형 공작물의 출입이 가능하도록 일단의 문이 좌우로 개폐되는 미닫이 문(2)과 개방되어진 미닫이 문과 함께 회전축(3)을 중심으로 회전하는 회전문(4)의 이중 구조를 가진다. 회전문(4)은 회전축(3)을 중심으로 상부와 하부에 설치된 베어링에 의해서 작동되며 회전문의 회전을 제어하는 장치는 따로 사용되지 않고 있다. Conventionally, as shown in FIG. 1, the splash guard 1 has a sliding door 2 and an opening in which one end of the door is opened to the left and right so as to allow large workpieces to enter and exit from the left and right pans and the front part for preventing the splash of cutting oil and cutting chips. It has a double structure of a rotating door 4 which rotates about the rotating shaft 3 together with the sliding door. The revolving door 4 is operated by bearings installed on the upper and lower sides of the rotating shaft 3, and a device for controlling the rotation of the revolving door is not used separately.

이같이 설치된 종래의 스플래쉬 가드(1)의 회전문(4)은 대형 공작물의 설치로 인하여 크기가 크며 미닫이 및 회전문의 이중 구조로 인하여 중량이 많이 나간다. 그리고 대형 공작물의 운반을 위하여 크레인을 사용하게 되므로 스플래쉬 가드의 상부가 개방되어 있는 구조를 가지게 됨에 따라 회전축(3)의 지지 강성이 부족하여 다음과 같은 문제를 야기한다.The revolving door 4 of the conventional splash guard 1 installed as described above has a large size due to the installation of a large workpiece and a large weight due to the double structure of the sliding door and the revolving door. And since the crane is used for transporting large workpieces, as the upper portion of the splash guard has an open structure, the supporting rigidity of the rotating shaft 3 is insufficient, causing the following problems.

첫째, 회전문의 회전 시에 무거운 중량에 의해서 많은 진동이 발생하여 원활한 회전을 방해하게 된다. 이러한 진동은 스플래쉬 가드 전체에 영향을 주게 되어 스플래쉬 가드의 강성을 저하시키게 된다.First, when the revolving door rotates due to heavy weight, a lot of vibration is generated to prevent smooth rotation. This vibration affects the entire splash guard, thereby lowering the stiffness of the splash guard.

둘째, 회전문의 회전을 제어할 수 있는 장치가 없으므로 회전문이 고속으로 회전하게 되면 스플래쉬 가드와의 좌우측 팬스와의 충돌로 인하여 파손이 발생 할 수 있다. Second, since there is no device that can control the rotation of the revolving door when the revolving door rotates at high speed may be damaged due to the collision with the left and right pans with the splash guard.

셋째, 회전문의 회전을 제어하는 장치가 없으므로 진동 발생 시에 움직이게 되며 고속 회전 시 작업자와 부딪히게 되면 안전 사고가 발생할 수 있는 위험을 가지게 된다.Third, because there is no device for controlling the rotation of the revolving door is moved when the vibration occurs, and if you bump into the worker during high-speed rotation has a risk that a safety accident can occur.

결국, 공작기계 스플래쉬 가드의 회전축이 회전문의 크기와 무게에 비하여 지지 강성이 약하여 회전문이 회전하게 되면 진동이 발생하며 고속 회전 시에는 작업자의 안전 사고에 영향을 주게 되므로 회전문의 움직임을 부드럽게 하여 진동을 방지하고 고속 회전을 제어함으로써 작업자의 안전 사고를 방지함이 요구된다.As a result, the rotation axis of the machine tool splash guard is weaker than the size and weight of the revolving door, which causes vibration when the revolving door rotates and affects the safety accident of the operator during high speed rotation. It is required to prevent the safety accident of the operator by preventing and controlling the high speed rotation.

따라서 본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위한 것으로, 회전문이 회전함에 따라 내륜 돌기가 내륜과 외륜 사이에 주입된 오일 속에서 회전하게 되어 발생하는 저항력을 이용하여 진동을 방지하고, 회전문의 회전 속도를 제어하여 안정되고 부드러운 회전 개폐를 이룰 수 있도록 한 스플래쉬 가드의 회전문 댐핑 장치를 제공함에 그 목적이 있다.Therefore, the present invention is to solve the problems of the prior art as described above, by using the resistance generated by the inner ring protrusion rotates in the oil injected between the inner ring and the outer ring as the rotary door rotates, to prevent the vibration, It is an object of the present invention to provide a splash guard revolving door damping device to achieve a stable and smooth rotation opening and closing by controlling the rotation speed of the.

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

도 2는 본 발명에 따른 스플래쉬 가드의 회전문에 설치된 댐핑 장치의 사시도이고, 도 3은 본 발명에 따른 스플래쉬 가드의 회전문 댐핑 장치의 수직 단면도이고, 도 4는 도 3의 A-A선에서 본 평단면도이다.2 is a perspective view of a damping device installed on the revolving door of the splash guard according to the present invention, Figure 3 is a vertical sectional view of the revolving door damping device of the splash guard according to the present invention, Figure 4 is a cross-sectional view seen from the AA line of FIG. .

도 2 내지 도 4에서와 같이 회전문(4)은 베어링(5)을 통해 회전문 지지축(3)에 회전 가능하게 지지되어 있고, 상기 베어링(5)이 삽입된 베어링 하우징(30)은 회전문(4)에 일체로 고정되어 있다.2 to 4, the revolving door 4 is rotatably supported by the revolving door support shaft 3 through the bearing 5, and the bearing housing 30 into which the bearing 5 is inserted is revolving door 4. It is fixed in one piece).

상기 베어링 하우징(3)의 외주면에는 상기 회전문(4)의 외측 회전부(4b)에 연결되어 회전문(4)과 일체로 회전하는 내륜(6)이 삽입되어 있고, 상기 내륜(6)은 조정볼트(0)를 통해 베어링 하우징(3)과 연결되어 있다.An inner ring 6 is inserted into an outer circumferential surface of the bearing housing 3 to be connected to the outer rotating part 4b of the rotating door 4 and integrally rotates with the rotating door 4, and the inner ring 6 is an adjustment bolt ( It is connected to the bearing housing 3 via 0).

따라서 회전문(4)을 개폐 회전 조작시키면, 베어링 하우징(30)과 내륜(6)이 회전문(4)과 일체로 베어링(5)에 지지되어 회전 개폐된다.Therefore, when the rotary door 4 is opened and closed, the bearing housing 30 and the inner ring 6 are supported by the bearing 5 integrally with the rotary door 4 to be rotated and opened.

상기 회전문(4)의 내측 고정부(4a)를 지지하는 상기 회전문 지지축(3)에는 상기 내륜(6)의 외주면에 삽입된 외륜(7)이 장착되어 있다. The outer ring 7 inserted into the outer circumferential surface of the inner ring 6 is mounted on the rotating door support shaft 3 that supports the inner fixing part 4a of the rotating door 4.

이때 내륜(6)과 외륜(7)과의 사이에는 스프링(8)에 의해 내륜(7)이 상방으로들림되어 원형의 오일챔버(22)가 형성되어 있고, 이 오일챔버(22)에는 오일(9)이 채워져 있다.At this time, the inner ring 7 is lifted upward by the spring 8 between the inner ring 6 and the outer ring 7, and a circular oil chamber 22 is formed. 9) is filled.

상기 오일(9)은 상기 내륜(6)과 외륜(7)과의 사이에 장입되어 상기 회전문(4)의 회전시 내륜 돌기(11)와 오일챔버(22)와의 사이에서 댐핑 저항력을 일으키는 역할을 한다. 이때 오일챔버(22)는 외륜(7)에 형성된 외륜돌기(12)에 의해 2군데로 나누어진다.The oil 9 is charged between the inner ring 6 and the outer ring 7 to generate a damping resistance between the inner ring protrusion 11 and the oil chamber 22 when the rotary door 4 is rotated. do. At this time, the oil chamber 22 is divided into two places by the outer ring protrusion 12 formed in the outer ring (7).

여기서 내륜 돌기(11)는 내륜(6)의 저면에 하방으로 돌출된 것으로 본 실시예에서는 180도 간격마다 배치되어 모두 2개가 형성되어 있다. Here, the inner ring protrusions 11 protrude downward on the bottom surface of the inner ring 6, and are arranged at intervals of 180 degrees in this embodiment, and both of them are formed.

본 실시예에서 2개의 내륜돌기(11)는 각기 하나씩의 오일챔버(22)에 위치하도록 구성된다.In this embodiment, the two inner ring protrusions 11 are configured to be located in one oil chamber 22, respectively.

이와 같이 구성된 회전문 댐핑장치는 다음과 같이 동작한다.The revolving door damping device configured as described above operates as follows.

회전문(4)이 회전 개폐동작을 하게 되면, 회전문(4)에 연결된 내륜(6)이 외 륜(7)의 내주면에서 회전 운동을 하게 된다.When the revolving door 4 rotates and opens, the inner ring 6 connected to the revolving door 4 rotates on the inner circumferential surface of the outer ring 7.

이때 오일챔버(22)내를 이동하는 내륜돌기(11)에 의해 오일(9)은 내륜돌기(11)의 하방측 좁은 통로를 저항을 받으면서 통과하게 된다. 이러한 저항력으로 회전문(4)이 부드럽게 회전동작하게 된다.At this time, by the inner ring protrusion 11 moving in the oil chamber 22, the oil 9 passes through the narrow passage below the inner ring protrusion 11 while receiving resistance. With this resistance, the revolving door 4 is smoothly rotated.

이같이 부드럽게 동작하는 회전문(4)은 오일(9)의 댐핑력에 의해 진동을 흡수 방지하게 되는 것이다.The smoothly operating revolving door 4 is to prevent the vibration is absorbed by the damping force of the oil (9).

이같이 본 발명은 고정부인 외륜(7)과 회전부인 내륜(6) 사이에 주입된 오일(9)이 내륜 돌기(11)의 움직임을 유체 저항으로 저지함으로써 진동없이 부드럽게 동작한다.In this way, the oil 9 injected between the outer ring 7 which is a fixed part and the inner ring 6 which is a rotating part prevents the movement of the inner ring protrusion 11 by fluid resistance and operates smoothly without vibration.

한편, 상기 회전문(4)의 회전 속도를 제어하는 수단으로, 상기 내륜(6)을 상방으로 지지하여 오일챔버(22)를 유지하는 스프링(8)과, 상기 내륜(6)에 삽입되어 상기 회전문(4)을 지지하는 베어링 하우징(30)에 나사 체결되어 오일챔버(22)의 높이를 조정하는 조정볼트(20)로 구성될 수 있다.On the other hand, as a means for controlling the rotational speed of the revolving door (4), the spring (8) for holding the inner ring (6) upward to maintain the oil chamber 22, and inserted into the inner ring (6) and the rotating door (4) may be composed of an adjustment bolt 20 is screwed to the bearing housing 30 for supporting (4) to adjust the height of the oil chamber (22).

따라서 조정볼트(20)의 조작방향에 따라 오일챔버(22)의 높낮이가 조정되고 내륜돌기(11)를 통과하는 오일통로가 가변되며, 이로 인해 오일 저항이 변화되어져 회전문(4)의 회전속도를 조정하게 된다.Therefore, the height of the oil chamber 22 is adjusted according to the operation direction of the adjusting bolt 20, and the oil passage passing through the inner ring protrusion 11 is varied, thereby changing the oil resistance, thereby increasing the rotational speed of the rotary door 4. Will be adjusted.

또한, 본 발명의 다른 실시예로서 상기 회전문(4)의 회전 속도를 제어하는 수단으로, 상기 외륜(7)에 오일챔버를 구획하는 외륜돌기(12)를 구비하고, 상기 외륜돌기(12)와 내륜돌기(11)의 사이에 오일챔버와 연통된 두개 이상의 오일출입구(13)를 형성하고, 상기 두개의 오일출입구(13)를 연결하는 관로(5)에 오일의 유 량을 조정하여 회전문의 회전 속도를 제어하는 스로틀밸브(16)가 설치될 수 있다.In addition, as another embodiment of the present invention as a means for controlling the rotational speed of the revolving door 4, the outer ring 7 is provided with an outer ring projection 12 for partitioning the oil chamber, the outer ring projection 12 and Rotation of the revolving door by forming two or more oil inlets 13 communicating with the oil chamber between the inner ring protrusions 11 and adjusting the flow rate of oil in the conduit 5 connecting the two oil inlets 13. Throttle valve 16 for controlling the speed may be installed.

미설명 부호 '7a'는 '오일주입구'이다.Unexplained symbol '7a' is the 'oil inlet'.

따라서 내륜(6)의 회전 조작시 회전 조작방향에 따라 해당 오일챔버(22)내 오일이 일측 오일출입구(13)를 빠져나와 관로(15)에 설치된 스로틀밸브(16)를 경유한 후 타측 오일출입구(13)로 유입된다.Therefore, when the inner ring 6 is rotated, the oil in the oil chamber 22 exits the one oil inlet 13 and passes through the throttle valve 16 installed in the conduit 15 according to the rotation operation direction, and then the other oil inlet. Flows into (13).

이 과정에서 스로틀밸브(16)에 유체 저항이 걸려 회전문(4)의 고속 회전을 저속으로 제어하게 되는 것이다.In this process, the fluid resistance is applied to the throttle valve 16 to control the high speed rotation of the rotary door 4 at a low speed.

이같이 본 발명은 도 3 에서와 같이 내륜(6)은 회전문에 고정되며 외륜(7)은 회전문 지지축(3)에 고정되어 회전문(4)이 회전함에 따라 내륜(6)도 함께 회전하게 된다.As such, the present invention, as shown in FIG. 3, the inner ring 6 is fixed to the revolving door and the outer ring 7 is fixed to the revolving door support shaft 3 so that the inner ring 6 also rotates as the revolving door 4 rotates.

또한, 내륜(6)과 외륜(7) 사이에는 오일(9)이 주입되어 오일링(10)에 의해 밀폐되게 구성된다.In addition, the oil (9) is injected between the inner ring (6) and the outer ring (7) is configured to be closed by the oil ring (10).

따라서 도 4에서와 같이 회전문(4)과 일체로 내륜(6)이 회전함에 따라 내륜 돌기(11)가 오일챔버(22)내에서 오일(9)의 저항을 받게 되고, 동시에 외륜 돌기(12)는 내륜 돌기(11)의 회전으로 밀려 나오는 오일(9)의 흐름을 억제함으로써 저항력을 높여주게 된다.Accordingly, as the inner ring 6 rotates integrally with the revolving door 4 as shown in FIG. 4, the inner ring protrusion 11 receives resistance of the oil 9 in the oil chamber 22, and at the same time, the outer ring protrusion 12 Is to increase the resistance by suppressing the flow of the oil (9) pushed out by the rotation of the inner ring projection (11).

도 4 에서 외륜 돌기(12)는 내륜 돌기(11)가 회전하는 것을 적당한 위치에서 억제하여 회전문(4) 이 스플래쉬 가드의 좌우측의 팬스와의 충돌을 방지하는 스토퍼 역할을 하게 된다. In FIG. 4, the outer ring protrusion 12 suppresses the rotation of the inner ring protrusion 11 at an appropriate position, and serves as a stopper for preventing the collision of the rotary door 4 from the left and right pans of the splash guard.

이같이 본 발명은 고정부인 외륜(7)과 회전부인 내륜(6) 사이에 주입된 오일 이 내륜 돌기(11)의 움직임을 유체 저항으로 저지함으로써 회전문의 댐핑역할을 하게 되어 부드러운 회전개폐 동작을 얻을 수 있다.In this way, the oil injected between the outer ring 7 which is a fixed part and the inner ring 6 which is a rotating part prevents the movement of the inner ring protrusion 11 by fluid resistance, thereby acting as a damping function of the revolving door, thereby obtaining a smooth rotation opening and closing operation. have.

또한 각기 스로틀 밸브(16)와 조정볼트(20)에 의해 오일(9)이 통과되는 유체 통로의 단면을 조정하므로써 회전문(4)의 고속 회전을 제어하게 된다.In addition, the high speed rotation of the rotary door 4 is controlled by adjusting the cross section of the fluid passage through which the oil 9 passes through the throttle valve 16 and the adjustment bolt 20, respectively.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

상술한 바와 같이 본 발명의 스플래쉬 가드의 회전문 댐핑 장치에 따르면, 회전문이 회전하면서 내륜 돌기가 회전하게 되고 내륜과 외륜 사이에 주입된 오일에 의해 저항을 받게 되어 회전문의 진동을 방지하고 스플래쉬 가드의 좌우측 팬스 및 작업자와의 충돌을 방지하게 된다.As described above, according to the revolving door damping device of the splash guard of the present invention, as the revolving door rotates, the inner ring protrusion rotates and is resisted by the oil injected between the inner ring and the outer ring to prevent vibration of the rotating door and to prevent the left and right sides of the splash guard. This prevents collisions with fans and workers.

또한, 내륜에 설치된 조정볼트와 스프링에 의해 오일이 통과하는 통로의 높이를 조정하고 내륜 돌기의 회전에 의해 관로 유출입되는 오일의 유량을 스로틀 밸브를 사용하여 조정함으로써 회전문의 회전 속도를 제어하여 안전하고 부드러운 개폐 동작을 얻을 수 있다.In addition, by adjusting the height of the passage through which the oil passes through the adjustment bolt installed on the inner ring and the spring, and by adjusting the flow rate of the oil flowing into the pipe by the rotation of the inner ring using the throttle valve, it is safe to control the rotation speed of the revolving door. A smooth opening and closing operation can be obtained.
