본 고안은 공작기계의 공구 자동교환장치에 관한 것으로, 공작 기계의 공구 교환시 공구 테이블의 착탈이 자동으로 이루어지도록 하여 공구교환이 보다 용이하게 함으로서 공구교환에 소요되는 비작업시간을 단축하여 생산성을 향상토록 함에 그 목적이 있다.The present invention relates to an automatic tool changer of a machine tool, and the tool table is automatically detached when changing the tool of the machine tool, thereby making tool change easier, thereby reducing productivity by reducing the non-work time required for tool change. The purpose is to improve.
종래에는 공작기계의 공구를 교환함에 있어서 테이블 베이스에 작업하고자 하는 공구가 셀팅된 공구 테이블을 셀팅하기 위하여 고정 볼트로 고정하였기 때문에 한 공정이 끝나고 다른 공정으로 공구를 교체하려면 테이블 베이스에 공구 테이블을 취부시킨 클램프의 고정 볼트를 일일이 풀고 작업이 끝난 공구대가 셀팅된 공구테이블을 분리한 후, 작업하고자 하는 공구가 셀팅된 공구 테이블을 결합하여 다시 고정볼트로 죄어서 고정하여야만 되었기 때문에 이때 소요되는 비가공시간이 증대되는 것은 물론, 고정볼트의 조이는 위치와 클램핑 정도에 따라 공구의 정도에 변화가 생기기 때문에 정확한 셀팅이 어려울 뿐만 아니라, 고정볼트의 조임이 잘못되어 공구 테이블의 이탈됨으로서 발생되는 안전사고의 위험을 내포하고 있는 것이 허다한 현 실정이었다.In the past, the tool table to be worked on the table base was fixed with fixing bolts to select the tool table in which the tool base was selected. In order to replace the tool with another process, attach the tool table to the table base. After unscrewing the clamping bolts of the clamps and removing the tool table with the tool bar finished, the tool to be worked has to be tightened by fixing the bolts again by fixing the tool table. In addition to the increase, the tightening of the fixing bolt changes the degree of the tool according to the position and the clamping degree, which makes it difficult to accurately select the clamping bolt. Reality too much to do Respectively.
본 고안은 상기한 종래의 제결함을 감안하여 유압에 의한 단일 동작으로 공구 테이블의 착탈이 가능토록 한 것으로서, 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention is to allow the detachable of the tool table in a single operation by the hydraulic in consideration of the above-described conventional defects, as described in detail based on the accompanying drawings as follows.
테이블 베이스(1)에 공구가 취부된 공구 테이블(2)을 셀팅하여 공작물을 가공하는 공작기계에 있어서, 상기 테이블 베이스(1)에 서로 연통토록 형성된 실린더(1a)에 노치부(3a)가 형성된 피스톤(3), (3')을 각각 삽설하여 스프링(4)으로 탄지하고, 각각의 피스톤(3), (3') 양측에 탄접된 고정핀(5), (5'), (5"), (5"')이 공구 테이블(2)을 고정토록 구성한 것으로, 미설명 부호; 5A는 각 고정핀(5), (5'), (5"), (5"')의 선단에 형성되어 피스톤(3), (3')의 노치부(3a)와 서로 대응하는 경사부이며, 6은 유·공압공이며, 7은 고정핀(5), (5'), (5"), (5"')를 탄압하는 스프링이며, 8은 척, 9는 공작물, 10은 공구테이블(2)에 셀팅된 공구이다.In a machine tool for machining a workpiece by selecting a tool table (2) on which a tool is mounted on a table base (1), a notch (3a) is formed in a cylinder (1a) formed to communicate with each other on the table base (1). Inserting the pistons 3 and 3 'respectively, and tightening them with the springs 4, and fixing pins 5, 5', and 5 " abutted on both sides of each of the pistons 3 and 3 '. ), (5 "') is configured to fix the tool table 2, and not described; 5A is formed at the tip of each of the fixing pins 5, 5 ', 5 ", and 5"' and is inclined to correspond to the notches 3a of the pistons 3 and 3 '. 6 is a hydraulic / pneumatic hole, 7 is a spring clamping pins (5), (5 '), (5 "), (5"'), 8 is a chuck, 9 is a workpiece, 10 is a tool It is a tool selected on the table (2).
이와 같이 구성된 본 고안의 작용효과를 설명하면, 공구 교환장치(TURRET)없는 CNC선반에 있어서 공구의 교환은 많은 준비시간을 요하기 때문에 선반의 슬라이더인 테이블 베이스(1)에 각 공정에 따른 공구가 취부된 공구 테이블(2)을 미리 준비하였다가 그때그때 필요한 공구 테이블(2)을 셀팅하여서 작업을 하게 되는 것으로, 한 공정이 끝나고 다른 공정으로 작업을 교체하고자 할 때 실린더(1a)에 전달하는 유공압을 제어하는 솔레노이드밸브 작동스위치(도시하지 않음)을 ON하면 피스톤(3), (3')이 스프링(4)을 탄압하며, 내측을 밀리는 것과 동시에 각 피스톤(3), (3') 양측에 탄접되어 있던 고정핀(5), (5'), (5"), (5"')이 노치부(3a)로 탄삽되면서 괘정하였던 공구 테이블(2)을 해정하게 되어 공구 테이블(2)을 교환토록 하게 된다.Referring to the effect of the present invention configured as described above, since the tool exchange requires a lot of preparation time in the CNC lathe without the tool changer (TURRET), the tool according to each process is placed on the table base 1, which is the slider of the lathe. The prepared tool table (2) is prepared in advance, and then work is performed by holding the necessary tool table (2) at that time. The hydraulic pressure transmitted to the cylinder (1a) when one step is finished and the work is to be replaced by another step. When the solenoid valve actuating switch (not shown) to control the piston is turned ON, the pistons 3 and 3 'pressurize the springs 4 and push the inner side to the piston 3 and 3'. The fixed pins 5, 5 ', 5', 5 ', and 5' are pushed into the notch 3a to release the tool table 2, which is tightened. Will be exchanged.
상기한 상태에서 작업이 끝난 공구 테이블(2)을 해체하고, 다음 공정의 공구테이블(2)을 결합하여 공구교환이 완료되었을 때 솔레노이드밸브 작동스위치를 OFF시켜 실린더(1a) 내부의 유공압을 제거하면 스프링(4)의 탄발력에 의하여 피스톤(3), (3')이 외측으로 밀리면서 상기 피스톤(3), (3') 양측에 탄접되어 있던 고정핀(5), (5'), (5"), (5"')은 노치부(3a)의 경사면을 따라 외부로 돌출되면서 공구 테이블(2)을 괘정하게 된다.In the above state, after disassembling the tool table (2) and combining the tool table (2) in the next step, when the tool change is completed, the solenoid valve operation switch is turned off to remove the hydraulic pressure inside the cylinder (1a). Fixed pins (5), (5 '), which are in contact with both sides of the piston (3), (3') while the piston (3), (3 ') is pushed out by the spring force of the spring (4) 5 ") and 5" 'protrude outward along the inclined surface of the notch part 3a, and the tool table 2 is stabilized.
상기한 바와 같이 본 고안은 공구교환에 소요되는 비가공 시간을 단축시킴으로써 생산성을 증대하고 공구테이블을 항상 일정하게 셀팅시켜서 가공정도를 향상시키며, 작업중 셀팅 볼트의 이완으로 발생되는 안전사고를 미연에 방지토록 함은 물론 양 피스톤의 복귀력을 스프링의 탄발력에 의존토록 하여 정전시나 유, 공압 라인의 고장시에도 항상 안전하게 셀팅토록 하는등 그 실사용 가치를 일층 고양시킨 신규유용의 고안이다.As described above, the present invention increases productivity by shortening the non-working time required for tool change and improves the machining accuracy by constantly holding the tool table, and prevents safety accidents caused by the loosening of the lifting bolt during operation. It is a new utility design that enhances its practical value by making the return force of both pistons depend on the spring force of spring, so that it always sells safely in case of power failure or breakdown of oil and pneumatic lines.
