이하, 본 발명의 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

도 1 및 도 2를 참조하면, 본 발명에 따른 회전식 딘트 표면처리장치는 허브(10 ; hub)의 상부면(11)에 구동축(20)의 하단이 장착되고, 허브(10)의 둘레에 복수개의 사이드 수직면(12)이 일정한 간격으로 형성되고, 각각의 사이드 수직면(12)에 고정축(30)의 일단이 각각 연결되고, 각각의 고정축(30)에 링 형상으로 형성된 복수개의 딘트 회전체(DR ; DR1, DR2, DR3)가 독립적으로 끼워지며, 딘트 회전축(DR)이 고정축(30)에서 빠지지않도록 고정축(30)의 단부에 형성된 나선 체결부(31)에 너트(35)가 체결되고, 딘트 회전체(DR)의 외주면에 다수개의 초경 팁(40)이 장착된다. 1 and 2, the rotary nozzle surface treatment apparatus according to the present invention is characterized in that a lower end of a drive shaft 20 is mounted on an upper surface 11 of a hub 10, A plurality of side walls 12 are formed at regular intervals and one end of the fixing shaft 30 is connected to each of the side vertical surfaces 12 and a plurality of dirt rotating bodies The nut 35 is inserted into the screw engagement portion 31 formed at the end of the fixing shaft 30 so that the nozzle DR is independently inserted and the nozzle rotary shaft DR is not separated from the fixing shaft 30. [ And a plurality of carbide tips 40 are mounted on the outer circumferential surface of the die rotation body DR.

또한, 본 발명에 따른 회전식 딘트 표면처리장치는 고정축(30)과 딘트 회전체(DR ; DR1, DR2, DR3) 사이에 볼 베어링(50)이 배치되고, 중간에 배치된 딘트 회전체(DR2)와 이와 이웃하는 딘트 회전체(DR1, DR2) 사이에 스러스트 베어링(60)이 배치된다.In the rotary type surface treatment apparatus according to the present invention, the ball bearings 50 are disposed between the fixed shaft 30 and the dirt rotary drums DR1, DR2 and DR3, And the thrust bearings 60 are disposed between adjacent tooth rotors DR1 and DR2.

상기와 같이 구성된 본 발명에 따른 회전식 딘트 표면처리장치(1)는, 도 3에 도시된 것처럼, 그라인딩 머신(100)에 장착되고, 엔진(110)의 회전동력이 감속기(120)를 통해 구동축(20)으로 전달되어, 구동축(20)의 회전에 의해 허브(10)가 화살표(15) 방향으로 회전하게 됨으로써, 그라인딩 머신(100)이 화살표(105) 방향으로 직진하는 동안, 고정축(30)을 중심으로 딘트 회전체(DR)가 회전하게 되고, 딘트 회전체(DR)의 회전과정에서 초경 팁(40)이 표면(예를 들어, 도로 표면)을 연마하게 된다.3, the rotary nozzle surface treatment apparatus 1 according to the present invention constructed as described above is mounted on the grinding machine 100, and the rotational power of the engine 110 is transmitted to the driving shaft (not shown) through the speed reducer 120 20 so that the hub 10 is rotated in the direction of the arrow 15 by the rotation of the drive shaft 20 so that while the grinding machine 100 goes straight in the direction of the arrow 105, And the cemented carbide tip 40 polishes the surface (for example, the road surface) in the course of the rotation of the dam rotator DR.

이때, 바닥의 표면이 고르지 못하여, 어느 한 딘트 회전체(예를 들어, DR1)의 초경팁에 부하가 걸리게 되어도, 이와 이웃하는 딘트 회전체(DR2)는 자신의 볼베어링(50 ; 도 2 참조)과 스러스트 베어링(60)에 의해 고정축(30)을 중심으로 회전할 수 있게 됨으로써, 어느 한 딘트 회전체(DR1)의 부하가 이웃하는 딘트 회전체(DR2)에 영향을 주지않게 되고, 부하를 받고 있는 딘트 회전체(DR1)가 이웃하는 딘트 회전체(DR2)에 대해 상대적으로 헛돌 수 있어, 부하를 받고 있는 딘트 회전체(DR1)의 초경팁(40)이 파손되는 것을 방지할 수 있을 뿐만 아니라 부하를 받고 있는 딘트 회전체(DR1)가 이웃하는 딘트 회전체(DR2)의 연마작업에 영향을 주지 않게 된다.
At this time, even when the surface of the floor is uneven and a load is applied to the carbide tip of a certain one of the dam rotors (for example, DR1), the neighboring tooth rotator DR2 is rotated by its own ball bearing 50 The thrust bearing 60 and the thrust bearing 60 can rotate around the fixed shaft 30 so that the load of a single damper drum DR1 does not affect the adjacent dam rotating drum DR2, The tooth rotation body DR1 which is received can be relatively stalled relative to the neighboring tooth rotation body DR2 so that it is possible to prevent the cemented carbide tip 40 of the load rotary body DR1 from being damaged But the dirt rotary member DR1 under load does not affect the polishing operation of the neighboring rotary motion member DR2 adjacent thereto.
