본 발명은 세라믹 부싱에 관한 것으로, 더욱 상세하게 설명하면, LCD 패널 제조장비 등에 널리 사용되는 원통 형태의 세라믹 부싱에 관한 것으로, 몸체 상부에 볼트를 통해 결합 또는 분해될 수 있도록 덮개를 구비하여, 몸체의 내부에 설치되는 핀과 롤러로 구성된 구동부를 몸체로부터 이탈되지 않도록 하여 장기간 고장 없이 사용할 수 있도록 한 세라믹 부싱에 관한 것이다.The present invention relates to a ceramic bushing, and more specifically, to a ceramic bushing of a cylindrical form widely used in LCD panel manufacturing equipment, etc., having a cover to be coupled or disassembled through a bolt on the upper body, the body The present invention relates to a ceramic bushing which can be used for a long period of time by preventing a driving part composed of a pin and a roller installed inside the body from being separated from the body.

일반적으로 세라믹 부싱이라 함은, 도 1에 도시한 바와 같이, 단차진 원통 형태로 제작된 세라믹 몸체(1)에 핀(2)과 롤러(3)가 네 방향으로 배열되어 있는 형태로 구성되는바, 상기와 같이 형성된 세라믹 부싱은 LCD 패널 제조장비 등에서 널리 사용되는 것이다.In general, the ceramic bushing, as shown in Figure 1, is composed of a pin 2 and the roller 3 is arranged in four directions in the ceramic body (1) made of a stepped cylindrical shape bar , The ceramic bushing formed as described above is widely used in LCD panel manufacturing equipment.

이러한 종래의 세라믹 부싱은, 몸체(1)에 형성된 핀홀(2')에 핀(2)이 단순히 끼워지고, 그 양측에 접착제 등으로 핀(2)을 몸체에 고정시키거나 핀(2)의 양측을 뾰족하게 가공하여 인접하는 핀(2) 상호 간에 지지하도록 제작하였으나, 사용 시 부하나 열팽창에 의해 핀(2)이 빠지는 문제점이 빈번하게 발생하였고, 그로 인해 몸체(1)로부터 롤러(3)가 분리되는 문제점을 내포하고 있었다.In the conventional ceramic bushing, the pins 2 are simply inserted into the pinholes 2 'formed in the body 1, and the pins 2 are fixed to the body with an adhesive or the like on both sides thereof, or both sides of the pins 2 are provided. Was sharply processed to support the adjacent pins 2 to each other, but the use of the pins 2 frequently occurred due to load or thermal expansion during use, and as a result, the rollers 3 were removed from the body 1. It contained a separate issue.

상기와 같이 핀이 몸체로부터 빈번하게 빠짐에 따라 세라믹 부싱 전체를 교 체하여야 함은 물론이고, 세라믹 부싱의 교체 동안 LCD 패널 제조장비의 가동을 중단시켜야 함으로써 제조장비의 효율성을 크게 저하시킬 뿐만 아니라, 고가의 세라믹 부싱 전체의 교체에 따른 비용이 과도하게 소요되는 또 다른 문제점을 내포하고 있었다.As described above, as the pins are frequently removed from the body, the entire ceramic bushing must be replaced, and the operation of the LCD panel manufacturing equipment must be stopped during the replacement of the ceramic bushing, thereby not only significantly reducing the efficiency of the manufacturing equipment. Another problem is that the cost of replacing the entire expensive ceramic bushing is excessive.

이에 본 발명은 상기와 같은 문제점을 감안하여 발명한 것으로, 몸체 상부에 덮개를 형성하고 볼트결합을 통해 분해 및 결합되는 형태로 구성하되, 몸체의 내부에 설치되는 롤러가 각각 핀들이 상호 지지하는 형태로 결합되어 구동부가 몸체로부터 이탈되지 않고 장기간 고장 없이 사용가능하도록 함을 목적으로 한다.Therefore, the present invention was invented in view of the above problems, and the cover is formed on the upper part of the body and is configured to be disassembled and coupled through bolting, in which the rollers installed in the body each support each other. It is intended to be coupled to the drive unit so that it can be used for a long time without failure from the body.

또한, 핀의 부러짐이나 롤러의 마모 등과 같은 불가항력적인 교체요인이 발생할 경우에는 볼트를 풀어 덮개를 몸체로부터 분리한 후, 핀과 롤러만을 교체하여 재사용 가능하도록 함으로써 교체비용의 절감을 이룰 수 있도록 함을 또 다른 목적으로 한다.In addition, in case of force majeure replacement factors such as broken pins or wear of rollers, the bolts can be removed from the body by loosening the bolts, and only the pins and rollers can be replaced and reused to reduce the replacement cost. Another purpose.

It is located at the top of the stepped portion of the) to complete the installation of one side roller (31b).

그 후, 몸체(10)의 상부에 형성된 롤러공(12c)에 상부 롤러(31c)를 위치시키고, 상부 핀(32c)을 상부 핀홀(13c)에 관통시켜 상부 롤러(31c)의 설치를 완료한다.Thereafter, the upper roller 31c is positioned in the roller hole 12c formed on the upper portion of the body 10, and the upper pin 32c is penetrated through the upper pinhole 13c to complete the installation of the upper roller 31c. .

또한, 몸체(10)의 타측에 형성된 롤러공(12b)에 측면 롤러(31b)를 위치시키고, 측면 핀(32b)을 측면 핀홀(13b)에 관통시켜 측면 핀(32b)이 하부 핀(32a)의 단차진 부분의 상부에 위치하도록 함과 동시에 상부 핀(32c)의 후방을 폐쇄하도록 함으로써 타측면 롤러(31b)의 설치를 완료한다.In addition, the side roller 31b is positioned in the roller hole 12b formed on the other side of the body 10, and the side pin 32b is penetrated through the side pin hole 13b so that the side pin 32b is lower pin 32a. Installation of the other side roller 31b is completed by making it located in the upper part of the stepped part of and closing the back of the upper pin 32c.

그런 다음 마지막으로, 몸체(10)의 상부에 덮개(20)를 위치시킨 후, 볼트(21)로 몸체(10)와 덮개(20)를 결합함으로써 본 발명의 전체 조립을 완료한다.Then, finally, after placing the cover 20 on the top of the body 10, by combining the body 10 and the cover 20 with bolts 21 to complete the entire assembly of the present invention.

한편, 상기와 같이 조립된 본 발명의 롤러(31a, 31b, 31c) 또는 핀(32a, 32b, 32c)의 교체 시에는 상기 기재된 역순으로 진행하게 되는바, 볼트(21)를 풀어 몸체(10)와 덮개(20)를 분리한 후, 어느 한 쪽에 삽착된 측면 핀(32b) 또는 양측면 핀(32b)을 우선적으로 분리한 다음, 상부 핀(32c)과 하부 핀(32a)의 순서로 핀홀(13a, 13b, 13c)로부터 분리함으로써 본 발명의 분해를 완료한다.On the other hand, when replacing the roller (31a, 31b, 31c) or the pins (32a, 32b, 32c) of the present invention assembled as described above proceeds in the reverse order described above, the bolt (21) by loosening the body 10 And the cover 20 are separated, and then the side pins 32b or the side pins 32b inserted on either side are first removed, and then the pinholes 13a in the order of the upper pins 32c and the lower pins 32a. 13b, 13c) to complete the decomposition of the present invention.

상기와 같이 구성된 본 발명은, 몸체 상부에 덮개를 형성하고 볼트결합을 통 해 분해 및 결합되는 형태로 구성하되, 몸체의 내부에 설치되는 롤러가 각각 핀들이 상호 지지하는 형태로 결합되어 구동부가 몸체로부터 이탈되지 않고 장기간 고장 없이 사용가능한 효과가 있다.The present invention configured as described above, the cover is formed on the upper portion of the body and is configured to disassemble and combine through the bolt coupling, the rollers installed inside the body are coupled to each other in the form that the pins support each other the drive unit There is an effect that can be used without failure and long term failure.

또한, 핀의 부러짐이나 롤러의 마모 등과 같은 불가항력적인 교체요인이 발생할 경우에는 볼트를 풀어 덮개를 몸체로부터 분리한 후, 핀과 롤러만을 교체하여 재사용 가능하도록 함으로써 교체비용의 절감을 이룰 수 있는 또 다른 효과가 있다.In addition, in the case of force majeure replacement factors such as broken pins or wear of rollers, the bolts can be removed from the body by unscrewing the bolts, and only the pins and rollers can be replaced and reused to reduce the replacement cost. It works.
