Abstract

PURPOSE: A circular door of a machining center is provided to reduce the manufacturing cost and to effectively utilize a space by automatically opening/closing the circular door using a plurality of links. CONSTITUTION: Two circular doors(20a,20b) are automatically opened/closed about one rotation point by an air cylinder(30) and a plurality of link structures incorporated with the air cylinder(30). The link structure includes two links(40b) which are pivotably connected to the circular doors(20a,20b). The links(40b) are closed to each other when a piston rod(32) of the air cylinder(30) is expanded. When the piston rod(32) of the air cylinder(30) is compressed, the links(40b) are spaced from each other, so that each of the circular doors(20a,20b) is operated, thereby opening or closing an opening part(12) of a cover(10).

Description

링크구조를 이용한 머시닝센터의 원형도어{USE LINKAGE TO CIRCLE FORM DOOR OF MACHINING CENTER}Circular door of machining center using link structure {USE LINKAGE TO CIRCLE FORM DOOR OF MACHINING CENTER}

본 발명은 링크구조를 이용한 머시닝센터의 원형도어에 관한 것으로서, 더욱 상세하게는 좌, 우 양방향으로 나누어지고 서로 동일한 피봇점을 가지는 머시닝센터의 원형도어에 있어서, 하나의 실린더와 이 실린더에 연동하는 다수의 링크에 의해 자동으로 개폐되도록 하는 링크구조를 이용한 머시닝센터의 원형도어에 관한 것이다.The present invention relates to a circular door of a machining center using a link structure, and more particularly, in a circular door of a machining center which is divided in both left and right directions and has the same pivot point. The present invention relates to a circular door of a machining center using a link structure that is automatically opened and closed by a plurality of links.

일반적으로 공작물을 3차원으로 가공하도록 제작된 CNC 공작기계의 머시닝센터는 가공할 공작물을 넣거나 가공된 공작물을 빼내기 위해 자동적으로 개폐작동하는 도어를 구비하고 있다.In general, the machining center of a CNC machine tool manufactured to process a workpiece in three dimensions is provided with a door that automatically opens and closes to insert the workpiece to be processed or to remove the processed workpiece.

이러한 도어는 통상적으로 직사각형태를 이루고 있으나 공간을 효율적으로 이용하고, 또한 외관의 부드러움을 취하기 위해 최근에 들어 원형으로 많이 제작되고 있는 실정이다.Such doors generally have a rectangular shape, but in recent years, many doors have been manufactured in a circular shape in order to use space efficiently and to have a smooth appearance.

그러나 종래의 원형도어는, 양방향으로 나누어져 구성되고 서로 동일한 피봇점과 실린더를 이용하여 좌우 대칭되게 원운동으로써 개폐되는 구조를 가지고 있으나 이러한 도어구조를 개폐하기 위한 작동수단으로써 직선운동이나 회전운동만 가능한 실린더를 이용할 경우 개폐작동의 어려움에 의해 상기 실린더를 양방향으로나누어진 도어에 각각 설치해야 하는 문제점이 있었다.However, the conventional circular door has a structure that is divided in both directions and has the structure to be opened and closed by the circular movement left and right symmetrically using the same pivot point and the cylinder, but only linear movement or rotational movement as an operation means for opening and closing the door structure When using a possible cylinder, there was a problem in that the cylinders should be installed in the doors divided in both directions by the difficulty of opening and closing operation.

이러한 문제점은 실린더의 설치증가에 따른 비용상승과 공간을 제대로 활용하지 못하는 또 다른 문제점이 발생되었다.This problem is caused by the increase in the installation cost of the cylinder and another problem that does not properly utilize the space.

상기 도어부재의 회전중심점 근접측 커버에 위상차를 갖도록 하나의 에어실린더를 구비하며,It is provided with one air cylinder to have a phase difference in the cover near the rotation center point of the door member,

상기 에어실린더의 피스톤로드 끝단의 링크 브래킷에 각 끝단이 피봇결합되고 각 타단이 서로 대칭되게 각 원형도어부재에 피봇결합되는 두 개의 연동링크를 구비 설치하되, 각 연동링크는 피스톤로드의 신장시 좁혀지고 압축시 벌어지면서 각 원형도어부재를 원궤적으로 작동시켜 커버의 개방부를 여닫을 수 있도록 한 특징을 갖는다.Each end is pivotally coupled to the link bracket of the piston rod end of the air cylinder and each other end is provided with two interlocking links pivotally coupled to each circular door member so that each end link is narrowed when the piston rod is extended.

Has a configuration.

상기와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

도 6 의 (가)에서와 같이 원형도어 즉 원형도어부재(20a)(20b)가 닫혀있는 상태에서 가공할 공작물을 커버(10)의 개방부(12) 내부로 진입시키거나 가공한 공작물을 그 개방부(12)로부터 인출시키고자 하는 단계가 되면 에어실린더(30)가 작동되어 피스톤로드(32)가 신장상태에서 수축상태로 바뀌는 스트로크가 발생된다.As shown in (a) of FIG. 6, the workpiece to be processed or the workpiece to be machined into the opening 12 of the cover 10 or the workpiece to be processed in the state where the circular door, that is, the circular door members 20a and 20b are closed is When the stage is to be withdrawn from the opening 12, the air cylinder 30 is operated to generate a stroke in which the piston rod 32 is changed from the extended state to the contracted state.

상기 피스톤로드(32)의 수축 스트로크는 그 로드 끝단의 링크 브래킷(42)에 일측단이 베어링(44a) 결합되고 타측단이 각 원형도어부재(20a)(20b)에 비스듬하게 베어링(44b) 결합된 서로 대칭된 연동링크(40a)(40b)를 링크 브래킷(42)의 피봇축(43)의 위치이동에 따라 외향되게 벌어지도록 하면서 상기 원형도어부재(20a)(20b)를 센터 샤프트(22)를 회전중심점으로 좌, 우 대칭되게 궤적방향으로 개(開)시킨다.The contraction stroke of the piston rod 32 is one end of the bearing 44a is coupled to the link bracket 42 of the rod end and the other end is obliquely coupled to the respective circular door members 20a and 20b. Centering the circular door members 20a and 20b with the symmetrical interlocking links 40a and 40b unfolded outward as the pivot shaft 43 of the link bracket 42 moves. Open in the trajectory direction symmetrically left and right with the rotation center point.

이와 반대로 상기 피스톤로드(32)에 신장 스트로크가 발생되면 그 로드 끝단의 링크 브래킷(42)의 피봇축(43)에 일측단이 베어링(44a) 결합되고 타측단이 각 원형도어부재(20a)(20b)에 베어링(44b) 결합된 벌어진 상태의 연동링크(40a)(40b)가 링크 브래킷(42)의 위치이동에 따라 내향되는 방향으로 오무려 들면서 상기 원형도어부재(20a)(20b)를 센터 샤프트(22)를 회전축으로 원궤적을 가지면서 도 6 의 (가)와 같이 폐(閉)된다.On the contrary, when an extension stroke occurs in the piston rod 32, one end of the bearing 44a is coupled to the pivot shaft 43 of the link bracket 42 of the rod end, and the other end of each of the circular door members 20a ( Centering the circular door members 20a and 20b while the interlocking links 40a and 40b in the opened state coupled to the bearing 44b are squeezed in an inward direction as the link bracket 42 moves. The shaft 22 is closed as shown in FIG. 6A while having a circular locus as the rotation axis.

이상에서 설명한 본 발명은 전술한 실시예 및 도면에 의해 한정되는 것은 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

이상에서와 같은 본 발명은 하나의 에어실린더와 이와 연동하는 다수의 연동링크의 조합에 의해 상기 에어실린더의 신축작용만으로 양방향의 원궤적을 갖는 원형도어의 개폐동작을 수행할 수 있기 때문에 최근에 들어 선호하는 원형도어에 원활히 적용할 수 있을 뿐만 아니라 에어실린더의 추가설치가 필요없기 때문에 부품수가 줄어들고 이에 따라 원가가 절감되며 생산성 향상에도 기여할 수 있는 효과가 기대된다.As described above, the present invention has recently been performed because the opening and closing operation of the circular door having a bidirectional circular trajectory can be performed only by the expansion and contraction action of the air cylinder by a combination of one air cylinder and a plurality of interlocking links interlocked with the air cylinder. Not only can it be applied to the preferred round door smoothly, but also the additional installation of the air cylinder is not necessary, which reduces the number of parts, thereby reducing the cost and contributing to the improvement of productivity.
