Description
본 발명은 유압치구용 ATC 도어장치, 보다 상세하게는 머시닝센터의 유압치구용 ATC(Auto Tool Changer) 도어의 구조를 보다 개선시키는 ATC 도어장치에 관한 것으로, 특히 유압치구를 사용하는 머시닝센터에 있어서 유압치구용 메인 커플러의 간섭을 배제하고 필요로 하는 ATC 도어의 열림량을 확보할 수 있도록 해주는 유압치구용 ATC 도어장치에 관한 것이다.The present invention relates to an ATC door device for hydraulic jig, and more particularly, to an ATC door device for improving the structure of an ATC (Auto Tool Changer) door for hydraulic jig of a machining center, in particular in a machining center using a hydraulic jig. The present invention relates to an ATC door device for a hydraulic jig to eliminate the interference of the main coupler for the hydraulic jig and to secure an opening amount of the required ATC door.
일반적으로 수평형 머시닝센터(machining center)에 있어 툴(tool)의 교환을 위해 설치되는 ATC(Auto Tool Changer)에는 공작물의 가공중 칩(chip)이나 쿨런트(coolant)의 침투를 방지하기 위해 별도의 커버가 설치되어, 상기 ATC가 보호되도록 구성되어 있다. 이때 툴의 자동교환을 수행하기 위한 상기 커버는 도어의 형태로 구성되면서 자동으로 열리고 닫히도록 되어 있다.In general, ATC (Auto Tool Changer), which is installed in the horizontal machining center to exchange tools, is used to prevent penetration of chips or coolants during machining of the workpiece. Is installed, the ATC is configured to be protected. At this time, the cover for performing the automatic replacement of the tool is configured to open and close automatically as configured in the form of a door.
도 1은 종래의 머시닝센터의 유압치구용 ATC 도어의 구조를 나타낸 평면 구성도로서, 에어 실린더(3)에 의해 작동되고 측면의 베어링(8)이 슬라이드 팩(7)에 의해 가이드되면서 개폐되는 ATC 도어(1)를 도시하고 있다.1 is a plan view showing the structure of an ATC door for a hydraulic jig of a conventional machining center, which is operated by an air cylinder 3 and an ATC which is opened and closed while a bearing 8 of a side is guided by a slide pack 7. The door 1 is shown.
일반적으로 머시닝센터의 유압치구라인은 유압유니트에서 나온 고압의 작동유를 이용하여 작동되는데, 상기 고압의 작동유는 메니폴드(manifold)를 통과하고 솔레노이드 밸브(solenoid valve)를 거쳐 제어되면서 메인 커플러(main coupler)를 통해 각각의 치구의 커플러로 보내져서 액츄에이터(actuator)를 동작시키게 되어 있다.In general, the hydraulic jig line of the machining center is operated by using a high pressure hydraulic oil from the hydraulic unit, the high pressure hydraulic fluid is passed through a manifold and controlled through a solenoid valve to maintain a main coupler. It is sent to the coupler of each jig through the actuator to operate the actuator (actuator).
그런데, 상기 유압치구 라인은 동작을 시키고자 하는 액츄에이터의 수량에 따라 그 만큼의 유압 라인이 메인 커플러로 공급되어야하므로, 그 수량이 많아질수록 메인 커플러가 상당히 커지게 된다.However, since the hydraulic jig line should be supplied to the main coupler as much hydraulic lines as the number of actuators to operate, the main coupler becomes considerably larger as the number thereof increases.
이러한 경우가 발생하게 되면 ATC 도어(1)의 열림량을 제한할 수 밖에 없게되어 가공상 길이가 긴 공구의 사용이 필요한 경우 불가피하게 수동으로 작업을 해야 하는 문제점이 발생할 수 밖에 없었고, 이러한 문제점은 공작물의 생산성을 저하시키는 요인으로 작용하였다.When this happens, there is no choice but to limit the amount of opening of the ATC door (1), so when the use of a tool with a long length is required, it is inevitable that there must be a problem of manual operation. It acted as a factor to lower the productivity of the workpiece.
본 발명은 상기와 같은 문제점을 감안하여 안출한 것으로서, 그 목적은 유압치구 라인과 이를 위한 유압치구용 메인 커플러가 구비된 머시닝 센터의 ATC 도어장치에 있어서, 상기 메인 커플러의 크기와 상관없이 간섭을 일으키지 않으면서 ATC 도어가 개폐가능하도록 ATC 도어에 일정한 공간부를 형성시키고 그 공간부를 커버하면서 작동하는 ATC 보조 도어를 구비함으로써, ATC 도어의 열림량을 제한하지 않아 사용하고자 하는 공구의 길이에 제한을 받지 않도록 해주는 머시닝센터의 유압치구용 ATC 도어장치를 제공함에 있다.The present invention has been made in view of the above problems, the object of the ATC door device of the machining center is provided with a hydraulic jig line and a hydraulic jig main coupler for the same, regardless of the size of the main coupler interference By forming a certain space in the ATC door so that the ATC door can be opened and closed without causing it, and having an ATC auxiliary door that operates while covering the space, the opening of the ATC door is not limited and the length of the tool to be used is not limited. To provide the ATC door device for the hydraulic jig of the machining center.
