Abstract

CRANK BAR에 고정된 영구자석과 반대 극이 형성되도록 CRANK BAR 좌 우에
거치된 전자석에 전류를 흐르게 하면 CRANK BAR를 당기게 되고 같은 극이 형성되도록 전류를 흐르게 하면 서로 강하게 밀어 내게 되는데 이때 발생된 진자 운동을 DRAW BAR ASSEMBLY(B)가 직선 운동으로 변환 시켜 CHUCK을 작동 시키는데, CHUCK대신 다른 장치를 사용하는 곳에는 DRAW BAR ASSEMBLY대신 CRANK ARM이나 FINGER JAW등 다른 장치를 사용하여 공작물을 고정시킨다.
On the left and right sides of the CRANK BAR so that the opposite pole is formed with the permanent magnet fixed to the CRANK BAR.
When current flows through the mounted electromagnet, it pulls the CRANK BAR, and when current flows so that the same poles are formed, they strongly push each other. The pendulum motion generated at this time is converted into linear motion by the DRAW BAR ASSEMBLY (B) to operate the CHUCK. In places where other devices are used instead of CHUCK, other devices such as CRANK ARM or FINGER JAW are used instead of DRAW BAR ASSEMBLY to fix the workpiece.

Description

전자석 고정장치{MAGNETIC CLAMP}Electromagnet fixture {MAGNETIC CLAMP}

본 발명은 산업 설비의 각종 부품을 가공할 때 부품을 고정하는데 사용되는 장치를 기존의 유압을 사용하는 대신 자력을 이용하는 새로운 개념으로 고안된 장치이다The present invention is a device designed with a new concept that uses magnetic force instead of the existing hydraulic pressure to fix the device used to fix the parts when processing various parts of industrial equipment.

현재 사용되고 있는 각종 산업 설비에는 유압 실린더의 힘을 이용한 클램프 방식이 적용되고 있는데 이 유압 실린더의 힘을 생성시키기 위해 설비를 ON 하는 순간부터 OFF 할때까지 유압 펌프가 쉬지 않고 가동되야 하므로 소음, 진동은 물론 에너지의 낭비와 기름으로 인한 환경 오염의 노출등 여러 문제가 있는것에 반해 이 장치는 자력의 힘을 이용해 부품을 고정하는 방식을 택하여 상기 서술한 문제들을 해결하고자 하는데 그 배경이 있다.A clamp method using the power of a hydraulic cylinder is applied to various industrial equipment currently in use. In order to generate the power of the hydraulic cylinder, the hydraulic pump must operate continuously from the moment the equipment is turned on until it is turned off, so noise and vibration are reduced. Of course, while there are various problems such as waste of energy and exposure to environmental pollution due to oil, the background of this device is to solve the problems described above by choosing a method of fixing parts using magnetic force.

영구 자석과 전자석의 힘으로 진자운동을 받게 된 CRANK BAR(C,C')가 DRAW BAR ASSEMBLY(B)를 직선 운동으로 변환 시킬 때 CHUCK에 연결된 ADAPTAR를 당기거나 풀어줌으로써 부품을 CLAMP, 또는 UN CLAMP 하게 된다 When the CRANK BAR (C, C'), which is subjected to pendulum motion by the power of a permanent magnet and an electromagnet, converts the DRAW BAR ASSEMBLY (B) into a linear motion, the part is CLAMPED or UN CLAMPED by pulling or releasing the ADAPTAR connected to the CHUCK. I will do it

강력한 영구 자석을 CRANK BAR(C,C')양면에 자석의 강 약에 맞춰 적절하게2~4개 고정시키고 진자 운동의 양쪽 끝점에 전자석을 미세 거리조정이 가능하도록 거치시켜 CRANK BAR을 당길때는 고정자석과 다른 극이 형성되도록 전류를 보내고 (이때 반대편 전자석에는 고정자석과 같은 극이 형성되게 하여 미는 힘이 발생되도록 함) 밀어 낼때는 같은 극이 되도록 전류 방향을 바꾸어 전자석을 작동 시키면 (F)의 축이 지렛대가 되어 CRANK BAR(C,C')의 진자 운동이 작은 힘으로 이루어 지더라도 DRAW BAR ASSEMBLY(B)에 전달되는 직선 운동은 큰 힘으로 전달되며 고정점에 도달하게 될때는 고정자석의 N극과 전자석의 S극이 서로 강하게 당기게 되므로 제품을 고정하게 될때는 유압힘에 상응하는 힘이 작용하게 됨. 이 때 고정시키는 힘을 조절할 때는 전자석의 위치를 가깝게 또는 멀게 위치를 변화시켜 강,약을 조절하고(자력 게이지 확인) CHUCK이 회전할 경우 DRAW BAR ASSEMBLY(B)가 CRANK BAR에 회전 운동을 전하지 않게 설계함(DRAW BAR ASSEMBLY(B)내 두 개의 축이 분리 되어 있어 (CHUCK)의 회전 운동이 다른측 축에 전달되지 않음)Fix 2 to 4 strong permanent magnets on both sides of the CRANK BAR (C, C') appropriately according to the strength and weakness of the magnets, and mount the electromagnets at both end points of the pendulum movement to enable fine distance adjustment, so that they are fixed when pulling the CRANK BAR. Send current so that a different pole from the magnet is formed (at this time, the same pole as the fixed magnet is formed in the opposite electromagnet to generate a pushing force). When pushing, change the direction of the current so that it becomes the same pole and operate the electromagnet (F). Even though the axis acts as a lever and the pendulum movement of the CRANK BAR (C, C') is achieved with a small force, the linear motion transmitted to the DRAW BAR ASSEMBLY (B) is transmitted with a large force, and when it reaches the fixed point, the fixed magnet's Since the N pole and the S pole of the electromagnet are strongly pulled together, a force equivalent to hydraulic force is applied when fixing the product. At this time, when adjusting the fixing force, adjust the strength or weakness by changing the position of the electromagnet closer or further away (check the magnetic force gauge). When the CHUCK rotates, make sure that the DRAW BAR ASSEMBLY (B) does not transmit rotational motion to the CRANK BAR. Designed (The two axes in DRAW BAR ASSEMBLY (B) are separated, so the rotational movement of (CHUCK) is not transmitted to the other axis.)

유압 탱크와 유압 펌프, 유압 실린더가 필요치 않아 제작비가 절감 되고 유압 펌프를 가동하지 않아도 되기에 에너지 절감및 소음 감소는 물론 기름 유출에 의한 환경 오염까지도 예방되는 효과를 볼수 있다.Since there is no need for a hydraulic tank, hydraulic pump, or hydraulic cylinder, production costs are reduced, and since there is no need to operate the hydraulic pump, not only does it save energy and reduce noise, but it also prevents environmental pollution caused by oil spills.

CRANK BAR에 고정된 영구자석과 반대 극이 형성되도록 CRANK BAR 좌 우에 거치된 전자석에 전류를 흐르게 하면 CRANK BAR를 당기게 되고 같은 극이 형성되도록 전류를 흐르게 하면 서로 강하게 밀어 내게 되는데 이때 발생된 진자 운동을 DRAW BAR ASSEMBLY(B)가 직선 운동으로 변환 시켜 CHUCK을 작동 시키는데, CHUCK대신 다른 장치를 사용하는 곳에는 (DRAW BAR ASSEMBLY)대신 (CRANK ARM 이나 FINGER JAW)등 다른 장치를 사용하여 공작물을 고정시킨다.When current flows through the electromagnets mounted on the left and right sides of the CRANK BAR so that opposite poles are formed from the permanent magnets fixed to the CRANK BAR, the CRANK BAR is pulled. When current flows so that the same poles are formed, they strongly push each other. The pendulum movement generated at this time is DRAW BAR ASSEMBLY (B) converts it into linear motion and operates the CHUCK. In places where other devices are used instead of CHUCK, other devices such as (CRANK ARM or FINGER JAW) are used instead of (DRAW BAR ASSEMBLY) to fix the workpiece.

강력한 영구 자석을 CRANK BAR(C,C')양면에 자석의 강 약에 맞춰 적절하게2~4개 고정시키고 진자 운동의 양쪽 끝점에 전자석을 미세 거리조정이 가능하도록 거치시켜 CRANK BAR을 당길때는 고정자석과 다른 극이 형성되도록 전류를 보내고 (이때 반대편 전자석에는 고정자석과 같은 극이 형성되게 하여 미는 힘이 발생되도록 함) 밀어 낼때는 같은 극이 되도록 전류 방향을 바꾸어 전자석을 작동 시키면 (F)의 축이 지렛대가 되어 CRANK BAR(C,C')의 진자 운동이 작은 힘으로 이루어 지더라도 DRAW BAR ASSEMBLY(B)에 전달되는 직선 운동은 큰 힘으로 전달되며 고정점에 도달하게 될때는 고정자석의 N극과 전자석의 S극이 서로 강하게 당기게 되므로 제품을 고정하게 될때는 유압힘에 상응하는 힘이 작용하게 됨. 이 때 고정시키는 힘을 조절할 때는 전자석의 위치를 가깝게 또는 멀게 위치를 변화시켜 강,약을 조절하고 CHUCK이 회전할 경우 DRAW BAR ASSEMBLY(B)가 CRANK BAR에 회전 운동을 전하지 않게 설계함(DRAW BAR ASSEMBLY(B)내 두 개의 축이 분리 되어 있어 (CHUCK)의 회전 운동이 다른측 축에 전달되지 않음)Fix 2 to 4 strong permanent magnets on both sides of the CRANK BAR (C, C') appropriately according to the strength and weakness of the magnets, and mount the electromagnets at both end points of the pendulum movement to enable fine distance adjustment, so that they are fixed when pulling the CRANK BAR.

When pushing, change the direction of the current so that it becomes the same pole and operate the electromagnet (F).

At this time, when adjusting the fixing force, the strength or weakness is adjusted by changing the position of the electromagnet closer or further away. When the CHUCK rotates, the DRAW BAR ASSEMBLY (B) is designed so that it does not transmit rotational motion to the CRANK BAR (DRAW BAR The two axes in ASSEMBLY (B) are separated, so the rotational movement of (CHUCK) is not transmitted to the other axis)

CHUCK이 아닌 다른 치구나 장치에 적용할 경우 DRAW BAR ASSEMBLY(B)대신 (CRANK ARM이나 FINGER JAW)등 다른 클램프 방식을 택하면 됨.When applying to a fixture or device other than CHUCK, you can select a different clamp method such as (CRANK ARM or FINGER JAW) instead of DRAW BAR ASSEMBLY (B).
