본 발명은 도드락 장치용 공구에 관한 것으로, 보다 상세하게는 기기본체의 회전축에 설치되어 회전하면서 석재의 가공면에 파내는 방식으로 도드락 작업을 수행하는 도드락 장치용 공구에 관한 것이다.The present invention relates to a tool for a lock device, and more particularly, to a tool for a lock lock device for performing the lock operation in a way that is installed on the rotating shaft of the machine main body while digging into the processing surface of the stone.

일반적으로 도드락 작업이라는 것은 석재의 가공면을 초경이 부착되어 있는 공구로 두들겨 석재 표면을 오돌토돌하게 하는 작업을 말한다. 즉, 원석을 판 형상으로 절단하면 그 가공면이 매끄럽게 되는 데, 이러한 매끄러운 면을 미끄럼방지나 장식을 위해 오돌토돌하게 다듬는 작업을 말한다.In general, the dodak work refers to a work in which a stone surface is beaten with a tool having a cemented carbide attached to it. In other words, when the raw stone is cut into a plate shape, the processed surface is smoothed, which refers to the work of smoothing the smooth surface for non-slip or decoration.

종래의 도드락 작업은 저면에 초경 돌편이 구비된 도드락망치를 이용하여 작업자가 수작업으로 석재를 두들여서 고르게 마무리를 하는 것이 보통인데, 이와 같은 수동식 도드락 작업은 힘이 많이 들고 상당한 주의가 요구되기 때문에 작업성 및 생산성이 저하되는 문제점이 있다. 또한, 도드락망치를 이용한 타격 방식으로 도드락 작업을 실행하다보면 석재에 충격 및 무리가 가해지는 단점이 있다.Conventional dodlock work is usually finished by hand tapping stone by hand using a dodlock hammer equipped with cemented stone on the bottom. Such a manual dodlock work requires a lot of power and requires great care. Therefore, there is a problem in that workability and productivity are lowered. In addition, there is a disadvantage in that the impact and force is applied to the stone when the dorak operation by the hitting method using a dorakkham hammer.

이러한 수동식 도드락 작업의 문제점을 개선하기 위해 근래에는 에어해머를 사용하여 도드락 작업을 훨씬 편리하게 수행하고 있다. 즉, 에어해머를 가공하고자 하는 부분으로 이동시키면 에어해머가 진동하면서 석재 표면을 타격하게 되는 것이다. 그러나 에어해머를 이용한 도드락 작업은 작업자가 에어헤머를 잡고 있기 때문에 에어해머의 진동력이 작업자에게 전달되어 작업자의 신체에 충격이 가해지면서 신체적인 부작용을 발생시키는 문제점이 있다. 또한, 에어해머를 이용하더라도 타격 방식으로 도드락 작업을 실행하다보면 석재에 충격 및 무리가 가해지는 단점이 있다.In order to improve the problem of the manual dodlock operation, in recent years, the air hammer is used to perform the dodlock operation much more conveniently. In other words, if the air hammer is moved to the portion to be processed, the air hammer will vibrate and hit the stone surface. However, the dodlock operation using the air hammer has a problem in that the vibration force of the air hammer is transmitted to the worker because the worker is holding the air hammer, and the body of the worker is impacted to generate physical side effects. In addition, even when using an air hammer, when the dodlock operation is executed in a hitting manner, there is a disadvantage in that impact and force are applied to the stone.

한편, 등록실용신안 제339051호에는 작업자가 숙련도에 따라 임의적으로 수행하는 도드락 작업을 기계로 자동화시킨 도드락 표면가공기가 개시되어 있다. 그러나 이와 같은 도드락 표면가공기도 도드락 작업을 타격 방식으로 실행하다보니 석재에 충격 및 무리가 가해지는 단점이 있다.On the other hand, Korean Utility Model Registration No. 339051 discloses a dodlock surface processing machine that automates a dodlock operation performed by a worker arbitrarily according to skill. However, such a dodak surface finisher also has a disadvantage in that impact and force is applied to the stone as the dodlock work is executed in a striking manner.
