커넥팅로드의 대단부에는 메탈베어링을 설치하게 되는데, 상기한 바와 같은 메탈베어링을 적절히 설치하여, 메탈베어링이 커넥팅로드의 대단부에 대하여 회전하거나 유동이 발생하는 것을 방지하기 위해서는, 커넥팅로드(500)의 대단부 내측에 도 1에 도시된 바와 같은 홈(502)을 형성하고, 메탈베어링에는 상기 홈에 삽입되는 돌기를 형성하여 서로 결합하여야 한다.A metal bearing is installed at the large end of the connecting rod. In order to properly install the metal bearing as described above, in order to prevent the metal bearing from rotating or flowing with respect to the large end of the connecting rod, the connecting rod 500 is provided. A groove 502 as shown in FIG. 1 is formed inside a large end of the metal bearing, and a protrusion inserted into the groove is formed in the metal bearing to be coupled to each other.

상기와 같은 홈(502)을 커넥팅로드(500)의 대단부에 형성하기 위해서는 도 2에 도시된 바와 같이 홈형성커터(504)가 구비된 스핀들(506)을 대단부 내측으로 삽입하여 홈(502)을 가공하고, 홈을 가공한 후에는 별도의 장치를 이용하여 상기 홈(502)의 형성시에 발생된 버(burr)를 제거하는 디버링 작업을 실시한다.In order to form the groove 502 as described above at the large end of the connecting rod 500, as shown in FIG. 2, the groove 502 is inserted into the spindle 506 provided with the groove forming cutter 504 into the large end. ), And after the groove is processed, a deburring operation is performed to remove burrs generated at the time of formation of the groove 502 using a separate device.

그런데, 상기와 같은 디버링 작업은 상기 홈형성커터(504)가 구비된 스핀들(506)이 장착된 장비와는 별도의 장비에 의해 이루어지므로, 작업대상 커넥팅로드(500)의 작업기준을 재설정하는 등과 같은 까다로운 세팅 작업이 필요하고, 자칫 디버링 작업이 적절하게 이루어지지 못하여 도 3에 도시된 바와 같이 버가 충분히 제거되지 못한 상태가 발생하기 쉽다.However, the deburring operation as described above is performed by a separate equipment from the equipment on which the spindle 506 with the groove forming cutter 504 is mounted, and thus resets the working standard of the working target connecting rod 500. The same demanding setting work is required, and deburring work is not performed properly, and as a result, burrs are not easily removed as shown in FIG. 3.

상기와 같이 버가 충분히 제거되지 못하게 되면, 엔진의 작동중에 버가 떨어져서 메탈베어링과 대단부 사이에 유동 및 스틱을 발생시켜서 메탈베어링을 손상시키는 문제점이 있다.If the burrs are not sufficiently removed as described above, the burrs may fall during operation of the engine, causing flow and sticks between the metal bearings and the large ends to damage the metal bearings.

본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 커넥팅로드의 대단부 내경부에 홈을 형성함과 아울러 가공된 홈의 디버링 작업을 함께 실시할 수 있도록 함으로써, 작업공정을 신속하고 단순하게 하며, 보다 향상된 디버링 품질을 확보할 수 있도록 함으로써, 엔진의 내구성을 향상시킬 수 있도록 한 커넥팅로드의 홈 가공 공구를 제공함에 그 목적이 있다.The present invention has been made to solve the problems described above, by forming a groove in the inner diameter of the large end of the connecting rod and by performing a deburring operation of the processed groove, the work process is quick and simple It is an object of the present invention to provide a grooving tool of the connecting rod that can improve the durability of the engine by enabling improved deburring quality.
