Description

휴대용 부시압입기 { Bush pressure apparatus }Portable Bush Press Apparatus

본 발명은 부시압입기에 관한 것으로, 보다 상세하게는 부시가 삽입되는 가공품에 고정몸체가 고정되며 상기 고정몸체 일측단에 고정된 실린더하우징에서 부시가 고정된 실린더로드가 작업자에 의해 직선운동되어 가공품에 부시가 고정될 수 있는 부시압입기에 관한 것이다.The present invention relates to a bush presser, and more particularly, a fixed body is fixed to a workpiece into which a bush is inserted, and a cylinder rod having a bush fixed in a cylinder housing fixed to one end of the fixed body is linearly moved by a worker to the workpiece. It relates to a bush presser in which the bush can be fixed.

일반적으로 부시(bush)는 기계 가공품에 형성된 구멍의 내측에 삽입되어 마모가 방지되도록 하는 금속, 고무 또는 복합소재가 원통형으로 가공되어 구멍 내측에 억지끼움 되어 사용되는 것으로, 억지끼움의 특성상 인력을 이용하는 것은 불가능하며 주로 별도의 프레스 장치를 이용해 작업이 이루어진다. In general, a bush is a metal, rubber, or composite material that is inserted into an inside of a hole formed in a machined product to prevent abrasion, and is processed into a cylindrical shape and used by being pressed into the inside of the hole. This is not possible and mainly works with a separate press device.

이와 같은 종래 기술로 대한민국 공개실용신안공보 (제20-124380호)“부시 압입용 지그”는 도 1에 도시된 사시도와 같이, 수개의 가이드홈(210)을 형성한 부시(200)가 너클의 링크부재(300)에 압입되는 것에 있어서, 원통형 지그본체(100)와; 이 지그본체(100)의 일측 주연부를 따라 부시(200)의 가이드 홈(210)에 대응하는 돌조(110)를 포함하여 이 돌조(110)가 가이드홈(210)에 일치되게 하여 타격되도록 형성된 구조로 이루어진다.In this prior art, the Republic of Korea Utility Model Publication (No. 20-124380) "bush press-fit jig" is a bush 200 formed with several guide grooves 210, as shown in Figure 1, the knuckle In press-fit into the link member 300, the cylindrical jig body 100 and; The protrusion 110 includes a protrusion 110 corresponding to the guide groove 210 of the bush 200 along a periphery of one side of the jig main body 100 so that the protrusion 110 hits the guide groove 210 to be hit. Is made of.

그러나 상기와 같은 종래기술은 별도의 장치를 이용해 가공하기 때문에 가공품의 구멍 내측을 별도의 공구를 이용해 가공 후 별도의 프레스와 같은 공구로 가공품을 이동해 부시를 삽입하게 되며, 부시 삽입 후에는 별도의 공구를 사용해 마무리 가공이 별도로 이루어지게 되어 한 공정을 완료 후 이동하는 과정으로 인해 공정시간이 연장되는 문제점이 있었다. 또한, 이동시 공정 진행에 따른 공정재고가 증가하고 각 공정에 따른 별도의 장치가 필요할 뿐만 아니라, 공정간 이동시 위치가 변경되어 정밀한 기계가공이 이루어지기 힘든 문제점이 있었다.However, since the prior art as described above is processed using a separate device, after processing the inside of the hole of the workpiece using a separate tool, the workpiece is moved to a tool such as a separate press to insert a bush, and after the bush is inserted, a separate tool There is a problem in that the processing time is extended due to the process of moving after finishing a process to be made separately using a finish process. In addition, the process inventory increases according to the progress of the process during the movement, as well as a separate device according to each process, as well as the position is changed during the movement between the process was difficult to achieve precise machining.

전술한 바와 같은 문제점을 해결하기 위하여, 본 발명에서는 크레인을 통해 부시압입기의 이동이 용이하도록 고정몸체 상단에 체결고리가 형성되고, 가공품에 용이하게 삽입되도록 'П자' 형상으로 고정몸체가 형성된 부시압입기를 제공하는데 목적이 있다.In order to solve the problems as described above, in the present invention, a fastening ring is formed on the top of the fixed body to facilitate the movement of the bush indenter through a crane, and the fixed body is formed in a 'П' shape so as to be easily inserted into the workpiece. The purpose is to provide a bush presser.
