도 1 내지 도 3을 참조하면, 본 발명의 실시예에 따른 방진 장치(100)는 지지대(110), 제 1 탄성부재(120), 예압 조절 부재(130), 오일 댐퍼(140), 고정부재(150), 를 포함할 수 있다.1 to 3, the vibration isolator 100 according to an embodiment of the present invention is the support 110, the first elastic member 120, the preload adjusting member 130, the oil damper 140, the fixing member 150, may include.
상기 지지대(110)는 본 발명의 실시예에 따른 방진 장치(100)의 상부에 위치한 기구물과 접촉한다. 즉, 상기 지지대(110)는 상기 기구물의 하부를 지지하여, 상기 기구물의 하중을 받게 된다. 이를 위해 상기 지지대(110)는 본 발명의 실시예에 따른 방진 장치(100)의 다른 구성에 비해 상부로 더 돌출될 수 있다.The support 110 is in contact with the mechanism located on the top of the dustproof device 100 according to an embodiment of the present invention. That is, the support 110 supports the lower portion of the appliance, and receives the load of the appliance. To this end, the support 110 may protrude further upward compared to other components of the dustproof apparatus 100 according to the embodiment of the present invention.
상기 제 1 탄성부재(120)는 상기 지지대(110)의 내측에 위치할 수 있다. 상기 제 1 탄성부재(120)는 상기 지지대에 가해지는 하중에 따라 수직 방향으로 압축되어 상기 하중에 의한 진동을 흡수할 수 있다. 또한, 상기 제 1 탄성부재(120)는 탄성 복원력을 통해, 상기 지지대(110)를 지지하여, 상기 지지대(110)가 상기 기구물을 지지하도록 할 수 있다. 즉, 상기 제 1 탄성부재(120)는 상기 기구물의 하부에 위치하여 수직 방향에서의 진동을 흡수하도록 구성된다. 이러한 제 1 탄성부재(120)는 스프링으로 도시되어 있으나, 고무나 공기 튜브와 같은 일정한 탄성력을 갖는 부재로서 대체되는 것도 가능하다.The first elastic member 120 may be located inside the support 110. The first elastic member 120 may be compressed in the vertical direction according to the load applied to the support to absorb the vibration caused by the load. In addition, the first elastic member 120 may support the support 110 through an elastic restoring force, such that the support 110 supports the apparatus. That is, the first elastic member 120 is configured to absorb the vibration in the vertical direction is located below the mechanism. Although the first elastic member 120 is shown as a spring, it may be replaced by a member having a constant elastic force, such as rubber or air tube.
상기 예압 조절 부재(130)는 상기 제 1 탄성부재(120)와 상기 고정부재(150)의 사이에 결합된다. 상기 예압 조절 부재(130)는 상기 고정부재(150) 중 바닥부(151)로부터 일정 높이로 돌출되며, 상기 제 1 탄성부재(120)의 하부를 지지한다. 따라서, 상기 예압 조절 부재(130)는 상기 제 1 탄성부재(120)을 상기 고정부재(150)의 바닥부(151)로부터 일정 높이만큼 유지시키는 역할을 수행하여, 상기 제 1 탄성부재(120)에 미리 일정한 탄성복원력 즉, 예압이 인가될 수 있도록 한다. 상기 예압 조절 부재(130)는 나사로 구성될 수 있으며, 이를 통하면 사용자가 필요에 따라 그 돌출되는 높이를 조절하여 예압을 조절할 수 있다.The preload adjusting member 130 is coupled between the first elastic member 120 and the fixing member 150. The preload adjusting member 130 protrudes from the bottom 151 of the fixing member 150 to a predetermined height, and supports a lower portion of the first elastic member 120. Therefore, the preload adjusting member 130 serves to maintain the first elastic member 120 by a predetermined height from the bottom 151 of the fixing member 150, the first elastic member 120 A predetermined elastic restoring force, i.e., a preload can be applied in advance. The preload adjusting member 130 may be composed of a screw, through which the user can adjust the preload by adjusting the protruding height as needed.
상기 오일 댐퍼(140)는 상기 지지대(110), 제 1 탄성부재(120) 및 예압 조절 부재(130)를 내부에 포함할 수 있다. 이러한 오일 댐퍼(140)는 내부에 오일(141)을 포함하고, 오일(141) 내에 상기 지지대(110), 제 1 탄성부재(120) 및 예압 조절 부재(130)의 구성을 내재한다. 따라서, 상기 오일 댐퍼(140)는 특히 상기 제 1 탄성부재(120)에서 발생한 진동을 감쇄시킬 수 있다. 결국 상기 오일 댐퍼(140)의 오일은 내부의 진동 감쇄를 통해 본 발명의 실시예에 따른 방진 장치(100)의 방진 특성을 더욱 향상시킬 수 있다.The oil damper 140 may include the support 110, the first elastic member 120, and the preload adjusting member 130 therein. The oil damper 140 includes an oil 141 therein, and has an internal structure of the support 110, the first elastic member 120, and the preload adjusting member 130 in the oil 141. Accordingly, the oil damper 140 may attenuate vibration generated in the first elastic member 120. As a result, the oil of the oil damper 140 may further improve the dustproofing property of the dustproof device 100 according to the embodiment of the present invention through vibration attenuation therein.
상기 고정부재(150)는 상기 방진 부재(100)의 하면과 측면에서 외벽을 형성할 수 있다. 이를 위해, 상기 고정부재(150)는 하부에 형성된 바닥부(151)와 측면에 형성되어 상기 바닥부(151)의 둘레를 따라 수직하게 형성된 측벽부(152)를 포함할 수 있다.The fixing member 150 may form an outer wall at the bottom and side surfaces of the dustproof member 100. To this end, the fixing member 150 may include a bottom portion 151 formed on a lower side and a side wall portion 152 formed on a side surface of the fixing member 150 and formed vertically along the circumference of the bottom portion 151.
상기 바닥부(151)는 대략 원형으로 형성될 수 있다. 후술할 바와 같이, 상기 바닥부(151)가 원형인 것은 이와 결합된 측벽부(152)로부터 상기 지지부(110)까지 연결된 상기 제 2 탄성 부재(160)가 대략 방사형으로 구비되기에 용이하다. 다만, 상기 바닥부(151)의 형상은 평면상에서 대칭으로 구비될 수 있다면, 다른 형상으로 변경되는 것도 가능하다.The bottom part 151 may be formed in a substantially circular shape. As will be described later, it is easy for the bottom part 151 to have a circular shape so that the second elastic member 160 connected to the support part 110 from the side wall part 152 coupled to the bottom part 151 is easily radially provided. However, if the shape of the bottom portion 151 can be provided symmetrically in the plane, it is also possible to change to another shape.

The side wall portion 152 may be formed to have a predetermined thickness and may be provided in the form of a substantially hollow steel pipe along the shape of the bottom portion 151. Therefore, the configuration of the support 110, the first elastic member 120, the preload adjusting member 130, and the oil damper 140 may be located in the inner space surrounded by the side wall part 152.
상기 제 2 탄성부재(160)는 상기 고정부재(150)의 측벽(152)과 상기 지지대(110)의 사이에 형성된다. 상기 제 2 탄성부재(160)는 복수개로 형성되며, 상기 측벽(152)에 일단이 고정되고, 상기 지지대(110)에 타단이 결합되며, 상기 지지대(110)를 중심으로 대략 외팔보의 형태를 가질 수 있다.The second elastic member 160 is formed between the side wall 152 of the fixing member 150 and the support 110.

보다 구체적으로, 상기 제 2 탄성부재(160)는 상기 측벽(152)에 결합된 수평부(161)와 상기 수평부(161)로부터 상기 지지대(110)를 향해 하방으로 형성된 수직부(162)를 포함할 수 있다.More specifically, the second elastic member 160 has a horizontal portion 161 coupled to the side wall 152 and a vertical portion 162 formed downward from the horizontal portion 161 toward the support 110. It may include.
상기 수평부(161)는 상기 측벽(152)의 둘레를 따라 복수개로 구비되며, 서로간에 간격(160a)을 통해 이격되어 형성된다. 상기 수평부(161)는 서로간에 대칭되는 평면 형태로 구비되며, 예를 들어, 상기 지지대(110)로부터 상기 측벽(152)까지 방사형을 이루도록 형성될 수 있다. 이로써, 상기 지지대(110)에 수평 방향에서의 진동이 흡수될 수 있도록 한다.The horizontal portions 161 are provided in plural along the circumference of the side wall 152, and are formed to be spaced apart from each other through a gap 160a. The horizontal portion 161 may be provided in a planar shape symmetrical to each other, for example, may be formed to be radial from the support 110 to the side wall 152. As a result, vibration in the horizontal direction may be absorbed by the support 110.
또한, 이를 위해, 상기 수평부(161)는 상기 측벽(152)과 결합된 단부에 내측으로부터 형성된 제 1 홈(160b)을 포함한다. 상기 제 1 홈(160b)에 의해 상기 수평부(162)가 일정한 정도로 유동되는 것이 가능하기 때문에, 진동을 흡수하는 것이 가능하다. 다만, 선택에 따라 상기 제 1 홈(160b)은 상기 수평부(161) 대신 또는 이와 함께 상기 측벽(152)의 연결부위에 형성되는 것도 가능하다.Also, for this purpose, the horizontal portion 161 includes a first groove 160b formed from the inside at the end coupled with the side wall 152. Since the horizontal portion 162 can be flowed to a certain degree by the first groove 160b, it is possible to absorb vibration. However, in some cases, the first groove 160b may be formed at a connection portion of the side wall 152 instead of or together with the horizontal portion 161.
상기 수직부(162)는 다수개로 형성되며, 상기 수평부(161)로부터 각각 연장되어 상기 지지대(110)에 결합된다.The vertical portion 162 is formed in plural, each extending from the horizontal portion 161 is coupled to the support 110.
한편, 상기 수평부(161)는 상기 수직부(162)와 연결되는 타단에 대해서도 내측으로부터 형성된 제 2 홈(160c)을 구비할 수 있다. 따라서, 상기 수평부(161)와 수직부(162)의 결합은 조인트 형태가 될 수 있으며, 수평 방향에서의 진동이 인가될 때, 상기 수평부(161)와 수직부(162)가 결합된 조인트를 중심으로 변형될 수 있다. 따라서, 상기 지지대(110)를 통해 기구물로부터 전달되는 진동 또는 외부로부터 상기 지지대(110)에 전달되는 진동을 최대한 흡수하여, 상기 기구물의 진동을 최소화할 수 있다. 다만, 상기 제 2 홈(160c) 역시 상기 수평부(161) 대신 또는 이와 함께 상기 수직부(162)의 연결부위에 형성되는 것도 가능하다.On the other hand, the horizontal portion 161 may include a second groove 160c formed from the inside of the other end connected to the vertical portion 162. Therefore, the coupling of the horizontal portion 161 and the vertical portion 162 may be a joint form, and when the vibration in the horizontal direction is applied, the joint in which the horizontal portion 161 and the vertical portion 162 are coupled It can be transformed around. Therefore, the vibration transmitted from the apparatus through the support 110 or the vibration transmitted to the support 110 from the outside can be absorbed as much as possible, thereby minimizing the vibration of the apparatus. However, the second groove 160c may also be formed at the connection portion of the vertical portion 162 instead of or together with the horizontal portion 161.
따라서, 본 발명의 실시예에 따른 방진 장치(100)는 외팔보 형상의 수평부(161)와 수직부(162)를 구비하되, 내부에 형성된 홈을 통한 조인트 구조로 형성함으로써, 부피 및 부품수는 증가시키지 않으면서도 강성을 유지하도록 할 수 있고, 이로써 수직 뿐만 아니라 수평 방향에서의 진동도 함께 흡수할 수 있다.Therefore, the vibration isolator 100 according to the embodiment of the present invention has a cantilever-shaped horizontal portion 161 and a vertical portion 162, by forming a joint structure through the groove formed therein, the volume and number of parts It is possible to maintain rigidity without increasing, thereby absorbing vibrations in the horizontal as well as vertical directions.
이하에서는 본 발명의 실시예에 따른 방진 장치(100)의 하중에 따른 변형 동작을 설명하도록 한다.Hereinafter, the deformation operation according to the load of the vibration isolator 100 according to the embodiment of the present invention.
도 4는 본 발명의 실시예에 따른 방진 장치에서 하중에 따른 강성 구조의 변형을 도시한 것이다.Figure 4 shows the deformation of the rigid structure according to the load in the vibration isolator according to an embodiment of the present invention.
도 4를 참조하면, 본 발명의 실시예에 따른 방진 장치(100)에 수직 방향으로 하중이 인가되는 경우, 상기 지지대(110)를 중심으로 아래로 향하는 변형이 이루어지게 된다. 또한, 이 경우, 하중은 붉은 색으로 표시된 지지대(110), 제 1 탄성부재(120) 및 오일 댐퍼(140)에 집중되며, 이에 따라 기구물의 하중에 의한 진동이 흡수될 수 있다.Referring to FIG. 4, when a load is applied to the vibration isolator 100 according to the embodiment of the present invention in a vertical direction, the deformation is made downward with respect to the support 110. In this case, the load is concentrated on the support 110, the first elastic member 120, and the oil damper 140, which are indicated in red color, and thus vibrations due to the load of the apparatus may be absorbed.
또한, 상기 제 2 탄성부재(160)는 상기 지지대(110) 등의 구조에 비해 상대적으로 적은 압력을 받게 되며, 상대적으로 유동이 가능할 수 있다. 따라서, 이 상태에서 수평 방향의 진동이 가해지는 경우, 상기 제 2 탄성부재(160)의 수평부(161)와 수직부(162)의 유동을 통해 수평 방향의 진동을 흡수할 수 있게 된다.In addition, the second elastic member 160 is subjected to a relatively low pressure, and may be relatively flowable compared to the structure of the support 110, and the like. Therefore, when vibration in the horizontal direction is applied in this state, it is possible to absorb the vibration in the horizontal direction through the flow of the horizontal portion 161 and the vertical portion 162 of the second elastic member 160.
