Description
본 발명은 자동공구교환장치의 링크구조에 관한 것으로서, 더욱더 상세하게는 공구를 잡아주는 링크에 스프링을 설치하여, 공구에 의해 과부하가 발생되는 것을 방지하여 내구부품이 파송되는 것이 방지되도록 하는, 자동공구교환장치의 링크구조에 관한 것이다.The present invention relates to a link structure of an automatic tool changer, and more particularly, by installing a spring on a link for holding a tool, to prevent overloading caused by the tool so that durable parts are prevented from being dispatched. The link structure of the tool changer device.
종래 자동공구교환장치의 링크구조는 구동모터에 복합캠이 회전가능하게 설치되고, 상기 복합캠에는 원통캠용캠팔로우와 회전용타렛캠팔로우 및 캠팔로우에구속된 전진로드링이 결합되어 있다.In the link structure of the conventional automatic tool changer, a combined cam is rotatably installed on a drive motor, and the combined cam is coupled to a cam follower for cylindrical cams and a forward load ring bound to a rotary cam follower and cam follower.
종래의 자동공구교환장치의 링크구조는, 바디에 설치된 구동모터가 회전하면 동일한 축에 설치된 복합캠이 회전하고, 상기 복합캠에 설치된 평면캠과 원통캠에 구속되어 있는 평면캠용캠팔로우 회전용타렛캠팔로우가 캠홈을 따라 돌면 평면캠에 설치된 캠팔로우의 운동량이 전지용링크를 거쳐 전진캠팔로우로 전하고, 캠팔로우에 구속된 전진로드링을 통해 전지로드를 전후진 시키며, 트윈암이 지정된 거리만큼 전 후진운동을 하면 회전용타렛캠팔로우는 원통캠의 캠홈을 따라 돌며 상기 캠팔로우과 연결된 회전용타렛이 회전하여 함께 연결된 트윈암이 회전하는 구조로 이루어진다.In the link structure of the conventional automatic tool changer, when the driving motor installed in the body rotates, the combined cam installed on the same axis rotates, and the cam follower rotating for the flat cam constrained by the flat cam and the cylindrical cam installed in the composite cam. When the Let Cam Follower moves along the cam groove, the momentum of the cam follower installed in the flat cam is transmitted to the forward cam follower through the battery link, and the front and back of the battery load are moved forward and backward by the forward load bound by the cam follower. Rotating cam cam follower is rotated along the cam groove of the cylindrical cam when the backward movement is made of a structure in which the twin arm is rotated by the rotary turret connected with the cam follower is rotated.
이때 전후진용로드는 바디의 외부까지 돌출되고, 전진시에도 일부 도출된다.At this time, the forward and backward rods protrude to the outside of the body, and are partially derived even when moving forward.
그러나 이와 같은 종래의 자동공구교환장치의 링크구조는, 동일한 트위암축에 회전기구인 회전타렛과 전후진기구인 전후진링크를 구성하여 놓음으로서, 전후진용로드가 전진거리만큼 바디의 외부로 돌출되어 설치영역이 커지게 되고, 최소구간에 자동공구장치를 설치하는 것이 불가능하게 되는 문제점이 있었다.However, the link structure of the conventional automatic tool changer is formed by forming the rotary tarlet as the rotating mechanism and the forward and backward link as the forward and backward mechanisms on the same twin arm shaft, so that the forward and backward rods protrude out of the body by the forward distance. There is a problem that the installation area becomes large, it becomes impossible to install the automatic tool device in the minimum section.
본 발명의 목적은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로서, 전진형로드를 제1링크와 제2링크로 분할하여 형성하고, 성기 제1링크와 제2링크에는 가동핀과 스프링을 설치하여, 스프링에 지정된 이상의 과부하가 발생시 가동핀과 제2링크가 분리되어, 내부부품 및 기구가 손상되는 것이 방지되도록 하는, 자동공구교환장치의 링크구조를 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, is formed by dividing the advanced rod into the first link and the second link, and the movable pin and the spring is installed on the first and second links of the genital Thus, when an overload specified in the spring occurs, the movable pin and the second link is separated, thereby providing a link structure of the automatic tool changer to prevent the internal parts and mechanisms from being damaged.
도 1은 본 발명의 실시예에 따른 자동공구교환장치의 링크구조를 보인 단면도이다.1 is a cross-sectional view showing a link structure of an automatic tool changer according to an embodiment of the present invention.

이하, 첨부된 도면을 참조로하여 본 발명의 그 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail as follows.
본 발명의 실시예에 따른 자동공구교환장치의 링크구조는, 도 1에 도시하고 있는 바와 같이, 전진형로드를 제1링크(10)와 제2링크(20)로 분할하여 형성하고, 성기 제1링크(10)와 제2링크(20)에는 가동핀(40)과 스프링(50)이 설치됨을 그 기술적 구성상의 기본 특징으로 한다.Link structure of the automatic tool changer according to the embodiment of the present invention, as shown in Figure 1, is formed by dividing the advanced rod into the first link 10 and the second link (20), The first link 10 and the second link 20 has a movable pin 40 and the spring 50 is installed as a basic feature of the technical configuration.
한편, 상기 제1링크(10)에는 스프링(50)의 압력을 지정하는 키이(70)가 설치됨을 밝혀 둔다.On the other hand, it is revealed that the key 70 for designating the pressure of the spring 50 is installed in the first link (10).
또한, 상기 제1링크(10)에는 가동핀(40)을 설치함이 바람직 하다.In addition, the first link 10 is preferably provided with a movable pin (40).
이와같이 구성되는 본 발명의 실시예에 따른 자동공구교환장치의 작용은 다음과 같다.The operation of the automatic tool changer according to the embodiment of the present invention configured as described above is as follows.
전진로드(60)가 전후진 작동중에 키이(70)에 의해 스프링(50)에 지정된 압력이상으로 과부하가 발생되면, 가동핀(40)이 제2링크(20)에 형성된 홈을 타고 후퇴하면서 빠져나오게 되고, 제1링크(10)와 제2링크(20)는 분리되며, 구동모타의 회전력을 받고 있는 복합캠(30)은 무부하 상태에서 계속해서 남은 캠사이클을 수행하고, 전후진중인 전진로드(60)는 정지된 상태로 있게 된다.If the forward rod 60 is overloaded by the key 70 during the forward and backward operation, the movable pin 40 is retracted while retreating through the groove formed in the second link 20. The first link 10 and the second link 20 are separated, and the composite cam 30 receiving the rotational force of the driving motor performs the remaining cam cycle continuously under no load, and the forward and backward moving rod 60 remains in a stopped state.
다시 자동공구교환을 수동조작으로 수행하면 제1링크(10)가 이틸된 위치에서 가동핀(40)이 후퇴하면서 처음의 이탈전 상태로 복귀하게 된다.When the automatic tool change is performed again by manual operation, the movable pin 40 is retracted from the position where the first link 10 is tilted to return to the initial disengagement state.
따라서 이러한 본 발명은 전진형 로드링크를 제1링크(10)와 제2링크(20)로 분리하는 가동핀(40)을 채용함으로써, 과부하시에도 내부부품의 파손이 발생되는 것이 방지되도록 하는 효과가 있다.Therefore, the present invention employs the movable pin 40 that separates the advanced road link into the first link 10 and the second link 20, thereby preventing damage to the internal parts even when overloaded. There is.
