Abstract

PURPOSE: Door opening structure of a machine tool with a moving point is provided to reduce the door installation space and parts by decreasing the distance between the door and the hinge with moving the center of rotation of the door, and to open the door actively and stably by interlocking two hinge points. CONSTITUTION: A door(18) opens and closes the inlet of a non-processing area(11) by revolving. A hinge bracket is installed in a fixing body formed in the non-processing area, and composed of a hinge guide hole formed along the specific radius of curvature. A door bracket(50) is connected to the hinge guide hole with two hinges(40,41), and fixed to the door. The position track is moved along the hinge guide hole with interlocking two hinges in opening and closing the door with turning. The installation space is reduced by decreasing the distance between the door and the hinge with interlocking the center of rotation.

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 1은 본 발명의 실시예에 따른 도어 개폐구조의 평면도로서 도어의 작동상태도이고, 도 2는 도 1의 A-A선 단면도이다.1 is a plan view of a door opening and closing structure according to an exemplary embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line A-A of FIG.

도 1,2에서와 같이 해당 영역(11)의 출입구를 회전식으로 개폐하는 도어(10)의 설치 구조에 있어서, 해당 영역(11)에 포함된 고정체(20)에는 소정의 곡률반경을 따라 형성된 힌지 안내장공(31)을 갖는 힌지브래킷(30)이 고정 설치되어 있다.In the installation structure of the door 10 for rotating and opening and closing the entrance and exit of the region 11, as shown in Figures 1 and 2, the fixed body 20 included in the region 11 is formed along a predetermined radius of curvature. A hinge bracket 30 having a hinge guide hole 31 is fixedly installed.

힌지 안내장공(31)의 길이는 도어(10)의 개폐량에 따라 증감될 수 있다.The length of the hinge guide hole 31 may be increased or decreased according to the opening and closing amount of the door 10.

본 실시예에서는 힌지 안내장공(31)의 곡률반경이 해당영역(11)내에 위치하고 있다. 여기서 해당영역(11)이란 예로, 공작기계의 경우 가공영역에 상대적인 의미로 사용하는 비가공영역을 의미한다.In this embodiment, the radius of curvature of the hinge guide hole 31 is located in the region 11. Here, the corresponding region 11, for example, means a non-processing region used in a machine tool relative to the machining region.

따라서 종래의 도 3과 비교해 볼때 힌지(13)가 가공영역에 위치해 있으나 본 발명은 비가공영역에 위치함을 알 수 있다.Therefore, the hinge 13 is located in the machining area, as compared with the conventional FIG. 3, but the present invention is located in the non-working area.

상기 힌지브래킷(30)과 도어(10)는 도어 브래킷(50)으로 연결되어 있다.The hinge bracket 30 and the door 10 are connected by a door bracket 50.

상기 도어브래킷(50)의 일단은 상기 힌지 안내장공(31)에 2지점 힌지(40,41)로 연결되어 있고, 그의 타단은 상기 도어(10)측에 통상의 연결수단인 예로, 체결볼트로 연결 고정되어 있다.One end of the door bracket 50 is connected to the hinge guide hole 31 by two-point hinges 40 and 41, and the other end thereof is a fastening bolt, for example, which is a normal connection means on the door 10 side. The connection is fixed.

상기 힌지(40,41)는 하나의 힌지로 구성하여도 도어(10)의 개폐에는 문제가없지만 도어(10)가 흔들림없이 안정적이고 원할한 개폐동작을 위해 바람직하게는 2지점의 힌지를 사용함이 좋다.Although the hinges 40 and 41 have a single hinge, there is no problem in opening and closing the door 10, but the hinge 10 is preferably used for a stable and smooth opening and closing operation without shaking the door 10. good.

본 실시예에서는 힌지(40,41)가 볼트로 구성되어 있으며, 이 볼트에 너트(42)가 체결되어 있다. 그리고 힌지(40,41)에는 힌지브래킷(30)의 힌지 안내장공(31)의 내면에 구름운동하는 베어링(43)이 결합되어 있다.In this embodiment, the hinges 40 and 41 are constituted by bolts, and nuts 42 are fastened to the bolts. And hinges (40, 41) is coupled to the rolling bearing 43 to the inner surface of the hinge guide slot 31 of the hinge bracket (30).

한편, 상기 도어(10)의 무게를 이기고 도어를 안내하기 위해 도어의 하단에는 주지의 가이드수단이 설치되어 있다.On the other hand, in order to overcome the weight of the door 10 and guide the door, well-known guide means are installed at the bottom of the door.

이와 같이 구성된 본 실시예의 작용을 설명한다.The operation of this embodiment configured as described above will be described.

도어(10)가 닫아져 있는 경우에는 도어(10)의 운동 중심은 힌지브래킷(30)측 힌지(40,41)의 중심이 된다.When the door 10 is closed, the movement center of the door 10 becomes the center of the hinge bracket 30 side hinges 40 and 41.

이 상태에서 도어(10)를 열면 도어(10)가 원주방향으로 열리고, 이에 연동하여 도어브래킷(50)의 힌지(40,41)가 힌지 안내장공(31)의 궤적을 따라 그 위치가 이동되고, 도어(10)가 완전히 닫히면 힌지(40,41)의 중심점은 이동된다.When the door 10 is opened in this state, the door 10 is opened in the circumferential direction, and the position of the hinges 40 and 41 of the door bracket 50 is moved along the trajectory of the hinge guide hole 31. When the door 10 is completely closed, the center point of the hinges 40 and 41 is moved.

이같이 본 발명은 도어(10)가 원호 운동으로 열리고 닫히면, 그 힌지(40,41)도 연동하여 해당영역(11)내에서 힌지 안내장공(31)의 궤적을 따라 원호 운동을 수행하면서 개폐동작이 이루어진다.As described above, when the door 10 is opened and closed by circular motions, the hinges 40 and 41 also interlock to perform circular motions along the trajectory of the hinge guide hole 31 in the corresponding region 11. Is done.

또, 2개의 힌지(40,41)로 회동이 이루어져 안정적이고 원활하게 개폐동작이 이루어진다.In addition, the rotation is performed by the two hinges (40, 41) to achieve a stable and smooth opening and closing operation.

상술한 바와 같이 본 발명의 이동회전점을 갖는 공작기계의 도어 개폐구조에따르면, 도어의 회전 중심점이 도어와 연동하여 이동되므로서 도어와 힌지간의 거리를 해당영역내에 포함되도록 단축시킬 수 있어 공작기계의 경우 비가공영역을 줄일 수 있고, 또 종래의 2도어에 비해 조립 단품수가 줄어든다.According to the door opening and closing structure of the machine tool having a moving rotation point of the present invention as described above, since the center of rotation of the door is moved in conjunction with the door, the distance between the door and the hinge can be shortened to be included in the corresponding area. In the case of the non-working area can be reduced, and the number of assembly parts compared with the conventional two doors is reduced.

또한 본 발명은 힌지점이 2지점을 지지되어 안정적이고 원활한 개폐 동작이 실현된다.In addition, the present invention is a hinge point is supported by two points to realize a stable and smooth opening and closing operation.
