상기 피동부(2)는 피동스프라켓(21)(21')을 동일방향으로 위치하여 마주보게하되, 각각의 피동스프라켓(21)(21')은 반분하여 맞대이는 일측에 결속부(23)를 마련하고 타측에는 회동핀(24)을 설치하여 다수개의 간격유지봉(29)으로 각각의 피동스프라켓(21)(21')에 결속하여 작업공간(22)을 마련하되, 피동스프라켓(21)(21')의 일측에는 각홈(27)을 한개이상 형성하고, 작업공간(22)에는 조절대(26)가 두개이상 등간격으로 간격유지봉(29)과 간섭을 피하고, 조절대(26)와 간격유지봉(29)의 간섭을 피하는 연마부(3)가 한곳이상 설치하는 것이다.The driven part 2 faces the driven sprockets 21 and 21 'in the same direction and faces each other, but each driven sprocket 21 and 21' is half-coupled with the binding part 23 on the opposite side. The other side is provided with a rotating pin 24 on the other side by binding to each driven sprocket 21, 21 'with a plurality of spacing retaining rod 29 to provide a working space 22, driven sprocket 21 ( 21 ') at least one groove (27) is formed on one side, the working space (22) has two or more adjusters (26) at equal intervals to avoid interference with the retaining rods (29), At least one polishing portion 3 is provided to avoid interference of the gap retaining rod 29.

상기 연마부(3)는 원통형의 연마재(31)의 내부에 모터(33)를 마련하여 연마재(31)와 모터(33)사이에 보호재(32)를 마련하고 모터(33)의 축은 각각의 피동스프라켓(21)(21')의 각홈(27)에 결속된다.The abrasive portion 3 provides a motor 33 inside the cylindrical abrasive 31 to provide a protective material 32 between the abrasive 31 and the motor 33, the axis of the motor 33 is driven each It binds to each groove | channel 27 of the sprockets 21 and 21 '.

이와 같이된 본 발명은 회동핀(24)에 의해 피동스프라켓(21)(21')이 회전하면 개구부(4)로 원형의 피가공물(5)이 피난공(28)에 위치하게 한후 피동스프라켓(21)(21')을 반회전하여 결속부(23)로 고정하고, 작업공간(22)에 위치한 다수개의 클램핑롤러(25)가 원형의 피가공물(5)의 외주면을 클램핑하도록 조절대(26)가 가변하여 고정되면, 원형의 피가공물(5) 외주면에 연마재(31)가 접촉하여 원형의 피가공물(5)을 가공하게 된다.In the present invention as described above, when the driven sprockets 21 and 21 'are rotated by the pivot pin 24, the circular workpieces 5 are positioned in the evacuation hole 28 by the openings 4, and then the driven sprockets ( 21 and 21 'by half-turning to fix it with the binding part 23, and a plurality of clamping rollers 25 located in the work space 22 clamp the outer circumferential surface of the circular workpiece 5. ) Is variable and fixed, the abrasive 31 is in contact with the outer peripheral surface of the circular workpiece (5) to process the circular workpiece (5).

그리고, 연마부(3)에 의해 원형의 피가공물(5) 일측이 연마작업 완료되면 구동부(1)의 모터(11)에 의해 체인(13)으로 피동부(2)로 전달되면 원형의 피가공물(5)의 외주면에 위치하는 클램핑롤러(25)에 의해 원형의 피가공물(5)은 정지되고 피동부(2)는 회전을 하여, 상기 연마부(3)가 원형의 피가공물(5) 외주전체면을 재가공 할 수 있는 것이다.When one side of the circular workpiece 5 is polished by the grinding unit 3, the circular workpiece is transferred to the driven unit 2 by the motor 11 of the driving unit 1 to the chain 13. The circular workpiece 5 is stopped and the driven portion 2 is rotated by the clamping roller 25 located on the outer circumferential surface of (5) so that the abrasive portion 3 is rotated around the circular workpiece 5. The whole surface can be reworked.

또한, 원형의 피가공물(5)의 외주의 외경과 폭의 가변에 따라 조절대(26)는 가변하도록 설치하고, 간격유지봉(29)과 연마부(3)는 교체하여 사용할 수 있는것이다.In addition, the adjuster 26 is installed to vary according to the change in the outer diameter and the width of the outer periphery of the circular workpiece 5, the gap retaining rod 29 and the grinding portion 3 can be used interchangeably.

상기와 같이 피가공물(5)에 피동부(2)를 고정하고 적정위치의 받침대(6)에 구동부(1)를 마련하여 구동스프라켓(12)과 피동부(2)의 피동스프라켓(21)(21')은 체인(13)으로 연결하여 작동되게 한다.As described above, the driven part 2 is fixed to the workpiece 5 and the driving part 1 is provided on the pedestal 6 at an appropriate position, thereby driving the sprocket 12 and the driven sprocket 21 of the driven part 2 ( 21 ') is connected to the chain 13 to be operated.

따라서, 본 발명은 상기한 바와 같이 대형선박이나 전동차등의 구동장치등과 같은 기계적인 장치에 적용하는 크랭크 축등의 피가공물(축봉)을 분해 할 필요없이 대형선박이나 전동차등의 장착된 상태에서 재가공이 이루어짐으로 가공시간과 가공비를 줄일 수 있는 이점이 있다.Therefore, the present invention can be reworked in the state of mounting a large vessel or an electric vehicle without disassembling the workpiece (shaft bar) such as a crankshaft applied to a mechanical device such as a large vessel or a driving apparatus such as an electric vehicle as described above. This has the advantage of reducing the processing time and processing costs.
