본고안은 선박추진용 엔진의 크랭크 샤프트 및 메인저널(main journal)의 불규칙적인 마모와 부분적인 소손을 규칙적으로 정밀하게 삭정할 수 있게 함을 목적한 선내용 크랭크샤프트 연삭기에 관한 것이다.This paper relates to an onboard crankshaft grinding machine which aims to enable regular and precise removal of irregular wear and partial burnout of the crankshaft and main journal of ship propulsion engines.

종래의 크랭크샤프트 삭정기는 비트(bit)를 크랭크축에 접촉시켜 크랭크축의 회전함으로서 삭정하는 것이므로 정밀하게 원형으로 연마할 수 없었는바 그 이유는 크랭크축이 마모되거나 소손되면 축의 주면의 각 부분마다 쇠의 강도가 불균일하여 일정한 강도로 단조된 비트로서는 균일하게 연마할 수 없으므로 연마시 크랭크축에 미세한 돌출부가 발생하는 등 정밀하게 가공할 수 없었으며 크랭크축을 회전시켜 삭정하므로 막대한 동력손실을 초래하는 등 여러가지 결점이 있었다.Conventional crankshaft cutters are made by cutting bits by contacting the crankshaft and rotating the crankshaft. Therefore, the crankshaft reducer could not be precisely polished in a circular manner. Because of the nonuniformity of the steel, the bit forged to a certain strength cannot be polished uniformly. Therefore, it could not be precisely processed, such as minute protrusions on the crankshaft during polishing. There was a flaw.

본 고안은 이와 같은 점을 감안하여 할개되는 원형의 프레임을 크랭크축에 괘착하고 체인으로 프레임을 회전되게 하되 프레임의 내면상단에 연삭숫돌 회전을 모타를 장착하여 연삭숫돌을 회전시킴으로서 서서히 회전되는 프레임의 상단에서 빠른 속도로 회전되는 연삭숫돌이 크랭크축을 정밀하게 삭정할 수 있게한 것인데 첨부도면에 따라 상술하면 다음과 같다.In view of the above, the present invention locks the circular frame to the crankshaft and rotates the frame with a chain, but the grinding wheel is rotated by rotating the grinding wheel on the inner surface of the frame. Grinding wheel that rotates at a high speed from the top to enable the crankshaft to be precisely cut as described above according to the accompanying drawings.

크랭크축(1) 삽입공(2')(3')이 각각 천공되고 체인휠(4)이 일측에 감각된 두개의 프레임(2)(3)사이에 다수개의 횡간(5)(5')을 착설하여 체결구(6)로서 활개되게 하고 안내공(7)이 중앙에 천공된 대판(8)의 일단을 횡간(5)에 유삽하여 보울트(9)(9')로 유착하고 타단은 타측의 횡간(5')에 재치하되 구멍(10)을 관통하여 대판(8)의 상부에 노출된 부분에 스프링(11)을 삽설한 단면 J자 형상의 받침간(12)으로 탄지시켜 조절보울트(13)로서 상하 승강케하는 한편 안내공(7)에는 취부체(14)가 일체로 부착된 모터축(15')을 삽설하여 그 끝단에 연삭숫돌(16)을 체착하며 대판(3)에 내부에는 이송나축(17)을 나삽한 회전축수(18)를 횡설하여 회전축수(18)의 회전으로 모터(15)를 좌우 이동시킬 수 있게한 구조이다.A plurality of transverses 5, 5 ′ between the two frames 2, 3 where the crankshaft 1 insertion holes 2 ′, 3 ′ are respectively drilled and the chain wheel 4 is sensed on one side. To install it as a fastener 6 and guide hole 7 is inserted into one end of the base plate 8 perforated in the transverse 5 to adhere to the bolts 9 and 9 'and the other end to the other side. The mounting bolt 12 'is mounted on the cross section 5' of the cross section, but the spring is inserted into the exposed portion of the upper plate 8 through the hole 10. 13) while moving up and down, while inserting the motor shaft 15 'with the mounting body 14 integrally attached to the guide hole (7), the grinding wheel (16) is attached to the end thereof, and the inside of the base plate (3) The rotating shaft number 18 inserted into the feed screw shaft 17 is rolled out so that the motor 15 can be moved left and right by the rotation of the rotating shaft number 18.

도면중 미설명부호 19,19'는 크랭크축(1)을 지지하는 메탈이고 20은 프레임(2)(3)을 회전시키는 감속모터이며 21은 체인이고 22는 메인저널을 연삭시 프레임(2)(3)을 고정시키는 고정구이다.In the drawings, reference numerals 19, 19 'are metal supporting the crankshaft (1), 20 is a reduction motor for rotating the frames (2) and (3), 21 is a chain, and 22 is a frame (2) when grinding the main journal. (3) It is a fixture for fixing.

이와같이 구성된 본 고안은 체결구(6)를 해리하여 프레임(2)(3)을 할개한 후 연삭하고자 하는 크랭크축(1)에 괘삽하여 체결구(6)를 체착하고 메탈(19)(19')로서 크랭크축(1)을 지지한 후 체인(21)으로 프레임(3)의 체인휠(4)과 감속모터(20)에 연결시켜 구동시키면 프레임(2)(3)이 크랭크축(1)의 외면을 활접하면서 회전하게 된다. 이때 프레임(2)(3)의 회전속도는 2-3RPM의 속도로 서서히 회전시켜 크랭크축(1)의 외면을 정밀하게 연삭할 수 있게 한다.The present invention configured as described above disengages the fasteners 6 to open the frames 2 and 3, and then inserts the fasteners 6 into the crankshaft 1 to be ground and attaches the fasteners 6 to the metal 19 and 19 '. After supporting the crankshaft (1) as a chain and connected to the chainwheel (4) and the reduction motor 20 of the frame (3) by the chain 21, the frame (2) (3) is the crankshaft (1) It rotates while sliding the outer surface of the. At this time, the rotational speed of the frame (2) (3) is rotated at a speed of 2-3RPM so that the outer surface of the crankshaft (1) can be precisely ground.

한편 프레임(2)(3)을 크랭크축(1)에 삽착한후 연삭숫돌(16)을 크랭크축(1)에 긴밀히 접촉시켜 마모부위로 완전하게 연삭할 수 있게 하여야 되는바 모터(15)가 대판(8)에 취부체(14)로 인하여 일체로 취부되어 있고 대판(8)은 일축을 횡간(5)에 유삽하여 보올트(9)(9')로서 유착하고 타축은 스프링(11)으로 탄설한 단면 J자 형상의 받침간(12)으로 탄지시켜 조절보울트(13)로서 조절되게 한 것이므로 조절보올트(13)를 조이면 대판(8)은 횡간(5)을 중구축으로 스프링(11)을 탄압하면서 상축으로 상승되고 조절보올트(13)를 해리하면 탄압된 스프링(11)이 복원되면서 대판(8)은 아래로 하강하게 되므로 연삭숫돌(16)을 크랭크축(1)에 긴밀하게 접촉시켜 연마할 수 있는 것이다.On the other hand, after inserting the frame (2) and (3) into the crankshaft (1), the grinding wheel (16) should be in close contact with the crankshaft (1) to be able to completely grind to the wear area bar motor (15) It is integrally attached to the base plate 8 due to the mounting body 14, and the base plate 8 is inserted into the transverse 5 by one axis to be adhered as the bolts 9 and 9 'and the other shaft to the spring 11. Since it is made to be adjusted as the adjusting bolt 13 by holding it with the j-shaped supporting rod 12 of the cross section, when the adjustment bolt 13 is tightened, the base plate 8 makes the transverse 5 the spring 11 by the middle axis. As the pressure rises to the upper shaft while dissociating the control bolt 13, the compressed spring 11 is restored and the base plate 8 is lowered, so that the grinding wheel 16 is in close contact with the crankshaft (1). It can be polished.

따라서 프레임(2)(3)은 감속모터(20)에 의해 동력을 전달받아 서서히 회전하면서 빠른게 회전하는 연삭숫돌(16)이 불규칙한 크랭크축(1)을 연삭하게되고 연삭도중에 불규칙한 부분에서는 연삭숫돌(16)이 스프링(11)을 탄압하면서 횡간(5)을 중심으로 미세하게 상승되므로 정밀하게 연마할 수 있으며 연삭부위를 좌우로 이동하고자 할 때는 대판(8)을 횡간(5)에 유착한 보올트(9)(9')를 해리하리 횡간(5)을 따라 이동시킨 후 다시 보올트(9)(9')로 고정하여 연마하면 되고 상하로 이동할 때는 회전축수(18)를 회전하여 이송나축(17)으로 모터(15)를 제도와 같이 이동시켜 사용하면 크랭크축(1)의 전체를 완전하게 연삭할 수 있는 것이다.Therefore, the frame (2) (3) is a grinding wheel (16) that rotates rapidly while being slowly rotated by the power received by the reduction motor (20) to grind the irregular crankshaft (1), and the grinding wheel in the irregular portion during the grinding (16) is finely raised about the transverse (5) while pressing the spring (11) can be precisely polished, and when moving the grinding site to the left and right beams that adhere the base plate (8) to the transverse (5) The olt (9) (9 ') is moved along the dissociation width (5), and then fixed with a bolt (9) (9') and polished again. When moving up and down, the rotating shaft (18) is rotated to feed the shaft. If the motor 15 is moved to a drawing as in 17, the entire crankshaft 1 can be ground completely.

그리고 메인저널(main journal)을 연마할 때는 프레임(2)(3)을 활개하여 반원형상의 프레임만을 가지고 제5도와 같이 고정구(22)로서 크랭크 하우징에 고정시켜 프레임은 정지된 상태에서 크랭크축(1)을 회전시키면 메인저널은 제자리에서 회전운동을 하게 되므로 간단한 구조로서 쉽게 연마할 수 있는 것이다.When grinding the main journal, the frame 2 and 3 are opened to have only a semi-circular frame to be fixed to the crank housing as the fixture 22 as shown in FIG. 5 so that the frame is in a stopped state. Rotating the main journal makes the main journal rotate in place so that it can be easily polished as a simple structure.

이와같이 본 고안은 크랭크축(1)은 정지된 상태에서 프레임(2)(3)을 회전시켜 빠른 속도로 회전되는 연삭숫돌(16)로서 연삭하므로 크랭크축 외면을 정밀하게 삭정할 수 있는 효과가 있다.As such, the present invention has the effect of precisely cutting the crankshaft outer surface because the crankshaft 1 is ground as a grinding wheel 16 which rotates at a high speed by rotating the frames 2 and 3 in a stopped state. .
