본 고안은 공작물의 표면을 정밀하게 다듬는데 사용하는 래핑머시인에 관한 것으로, 특히 래핑공구를 캠에 의해 상하요동시키고 공작물 재치대를 동력에 의해 승강조절할수 있게한 래핑머시인에 관한 것이다.The present invention relates to a lapping machine used to precisely polish the surface of a workpiece, and more particularly, to a lapping machine that allows the wrapping tool to swing up and down by a cam and the lifting and lowering of the worktable by power.

종래의 래핑머시인을 보면, 주로 공구를 회전시켜 래핑작업을 하였기 때문에, 내치차가 형성된 공작물등, 길이방향으로 요홈이나 돌출부가 형성되어 있는 특수한 공작물을 래핑하기는 불가능하였던 결점이 있었다.In the conventional lapping machine, since the lapping operation was performed mainly by rotating the tool, there was a drawback that it was impossible to wrap a special workpiece having grooves or protrusions formed in the longitudinal direction, such as a workpiece having an internal tooth.

본 고안의 목적은, 종래의 상기와 같은 문제점을 감안하여 모우터에 의해 회전하는 회전축에 캠을 축설하고, 캠의 하부에 캠에 의해 승강되는 공구대를 설치한 다음 공구대에 래킹공구를 착탈가능하게 취부할 수 있는 취부구조를 마련하며 이와 대항하는 하부 받침대에는 모우터에 의해 상,하조절되는 공작물 재치대를 설치하여 내치차가 형성된 공작물이나 내주연에 돌출부와 요흠등이 길이방향으로 형성되어 회전식 래핑작업이 불가능한 특수 공작물을 용이하게 래핑가능하게 하는 래핑머시인을 제공함에 있다.The object of the present invention is to accumulate a cam on a rotating shaft rotated by a motor in view of the above-described problems of the prior art, install a tool post lifted by the cam at the lower part of the cam, and then attach and detach the racking tool to the tool post. A mounting structure that can be mounted is provided, and the lower pedestal opposite to this is provided with a workpiece mounting stand that is adjusted up and down by a motor, and protrusions and recesses are formed in the longitudinal direction on the workpiece or inner circumference where the internal tooth is formed. The present invention provides a lapping machine that makes it possible to easily wrap a special workpiece that cannot be rotated.

이하, 본 고안의 한 실시예를 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

1은 기대로서, 상단받침대(2)와 중간받침대(3)가 양측 기둥(4)(4)에 의해 받쳐지고 양측기둥(4)(4)은 하부받침대(5) 위에 세워져 있다.1 is an expectation, where the upper base 2 and the intermediate base 3 are supported by both pillars 4 and 4, and both pillars 4 and 4 are erected on the lower base 5.

6은 회전축으로, 양단이 베어링(7)(7)에 의해 설치되고 중앙에 캠(8)이 축설되어 있으며 캠(8)의 일측에 종동풀리(9)가 축설되어 있다.6 is a rotating shaft, the both ends of which are provided by the bearings 7 and 7, the cam 8 is built in the center, and the driven pulley 9 is built in one side of the cam 8.

상기 종동풀리(9)는 모우터(11)의 축(12)에 설치된 구동풀리(13)와 벨트(14)를 연결되어 있다.The driven pulley 9 is connected to the drive pulley 13 and the belt 14 provided on the shaft 12 of the motor 11.

그리고, 상기 회전축(6)의 일단에는 핸들(10)이 착탈자재한 구조로 설치되어 있다.The handle 10 is attached to one end of the rotary shaft 6 in a detachable structure.

15는 공구대로서, 상,하단에 상판(16)과 하판(17)이 고정되어 있는 승강봉(18)이 중간받침대(3)에 관통설치되어 코일스프링(19)에 의해 탄설되고, 상기 상판(16)에는 캠(8)과 접동하는 로울러(20)가 축(21)으로 설치되고 하판(17)의 하부에는 공구(22)가 부착된 공구고정판(23)이 체결되어 있다.15 is a tool bar, the elevating bar 18, the upper plate 16 and the lower plate 17 is fixed to the upper and lower ends penetrated through the intermediate support (3) and coalesced by the coil spring (19), the upper plate The roller 20 which slides with the cam 8 is provided in the shaft 16 by the shaft 21, and the tool fixing plate 23 with the tool 22 attached to the lower part of the lower board 17 is fastened.

24는 중앙에 관통공(24')을 가진 공작물 재치대로서, 저면 중앙에 관통공(25')을 가진 나사봉(25)에 취부되어 있고, 나사봉(25)은 나사공을 가진 종동장치차(26)에 관통되어 나사결합되어 있으며, 상기 종동치차(26)는 중간치차(27)에 의해 구동치차(28)와 연결되며 구동치차(28)는 모우터(29)의 축(30)단에 설치되어 있다.24 is a worktable having a through hole 24 'at the center thereof, and is mounted on a screw rod 25 having a through hole 25' at the center of the bottom, and the screw rod 25 is a driven device having a screw hole. The driven gear 26 is screwed through the car 26, and the driven gear 26 is connected to the drive gear 28 by an intermediate gear 27, and the drive gear 28 is the shaft 30 of the motor 29. It is installed at the stage.

또, 상기 종동치차(26)는 하부받침대(5)에 고정편(31)으로 회전자재하게 설치되고 하부받침대(5)의 저면에는 나사봉(25)이 관통되는 키이판(32)이 부착되어 나사봉(25)의 키이홈(25")에 키이판(32)의 키이(32')가 걸리도록 설치된다.In addition, the driven gear 26 is rotatably installed in the lower support (5) by the fixing piece 31, the bottom plate of the lower support (5) is attached to the key plate 32 through which the screw rod 25 is penetrated It is provided so that the key 32 'of the key plate 32 may be caught in the key groove 25 "of the screw rod 25.

그리고, 상기 공작물재치대(24)의 일측 저면에는 수직안내봉(33)이 설치되어 있고 수직안내봉(33)이 하부받침대(5)에 삽입된 부싱(34)을 관통하도록 구성되어있다.In addition, a vertical guide bar 33 is installed at one bottom of the work mounting base 24 and the vertical guide bar 33 is configured to penetrate the bushing 34 inserted into the lower support 5.

미설명 부호 35는 공작물이다.Reference numeral 35 is a workpiece.

이상과 같이 구성된 본 고안은 모우터(29)를 회전시키면 그 회전력이 구동치차(28)와 중간치차(27)을 거쳐 종동치차(26)에 전달되고, 종동치차(26)가 회전하게 되면 이에 나사결합된 나사봉(25)이 승강된다. 나사봉(25)의 승강작용은 나사봉(25)의 키이홈(25")에 키이(32')가 물려 있으므로 종동치차(26)의 회전을 따라 나사봉(25)이 회전하지 못하므로 나사봉(25)은 승강하게 되는 것이다.The present invention configured as described above, when the motor 29 is rotated, the rotational force is transmitted to the driven gear 26 via the driving gear 28 and the intermediate gear 27, and when the driven gear 26 is rotated, The threaded screw rod 25 is lifted. The lifting action of the screw rod 25 is because the key 32 'is held in the key groove 25 "of the screw rod 25, so that the screw rod 25 cannot rotate along the rotation of the driven gear 26. Sabong 25 is to be raised and lowered.

나사봉(25)이 상기와 같이 승강되면 나사봉(25)의 상단에 고정된 공작물재치대(24)가 승강하게 된다.When the screw rod 25 is lifted as described above, the workpiece holder 24 fixed to the upper end of the screw rod 25 is lifted.

따라서, 공작물 재치대(24)에 공작물(35)을 장착시킬 때는 모우터(29)를 회전시켜 공작물 재치대(24)를 하강시킨뒤 공작물(35)을 장착시키고 장착완료되면 모우터(29)를 반대방향으로 회전시켜 공작물재치대(24)를 소정의 높이만큼 상승시켜 래핑작업을 하게 된다.Therefore, when mounting the workpiece 35 on the workpiece holder 24, the motor 29 is rotated to lower the workpiece holder 24, and then the workpiece 35 is mounted and the motor 29 is mounted. Rotate in the opposite direction to raise the workpiece holder 24 by a predetermined height to perform the lapping operation.

공작물 재치대(24)의 높이설정은 래핑공구(22)의 승강행정 범위에 맞추어 설정되어져야 하며 래핑공구(22)의 승강행정범위는 회전축(6)을 핸들(10)로 회전시켜 가면서 알아낼 수 있다.The height setting of the worktable 24 should be set in accordance with the lifting stroke range of the wrapping tool 22. The lifting stroke range of the wrapping tool 22 can be determined by rotating the rotation shaft 6 with the handle 10. have.

래핑공구(22)의 승강행정범위가 설정된 후에는 핸들(10)을 축(6)으로 부터 분리한 다음, 모우터(11)를 가동시키면 구동풀리(13)가 회전되면서 그 회전력을 종동풀리(9)를 통하여 회전축(6)에 전달시키므로 회전축(6)이 회전하게 된다.After the lifting stroke range of the lapping tool 22 is set, the handle 10 is removed from the shaft 6, and then the motor 11 is operated, and the driving pulley 13 is rotated, and the rotational force is driven by the driven pulley ( The rotary shaft 6 is rotated because it is transmitted to the rotary shaft 6 through 9).

회전축(6)이 회전하게 되면 캠(8)이 회전하면서 이와 접동하는 로울러(20)를 캠(8)의 형상에 의해 상,하 요동시키게 로울러(20)가 상하 요동되는 작용에 의하여 승강봉(18)이 승강하게 된다.When the rotating shaft 6 is rotated, the cam 8 rotates while the roller 20 swings up and down by the shape of the cam 8 so that the roller 20 swings up and down. 18) will be lifted.

승강봉(18)은 코일스프링(19)에 의해 항시 상승하려는 힘이 있기 때문에 로울러(20)는 캠(8)의 캠면에 완전 밀착된 상태에서 요동하게 된다. 승강봉(18)이 승강하면 그 하단에 부착된 하판(17)이 승강하면서 래핑공구(22)를 승강시켜 준다.Since the elevating bar 18 has a force to be always raised by the coil spring 19, the roller 20 is oscillated in a state in which it is in close contact with the cam surface of the cam (8). When the elevating rod 18 is elevated, the lower plate 17 attached to the lower end of the elevating rod 18 raises and lowers the lapping tool 22.

래핑공구(22)는 공작물(35)의 래핑작업 부위의 형상과 대응하는 형상으로 되어 있어 래핑작업이 가능하게 된다. 래핑작업시에는 공작물(35)과 래핑공구(22)의 마찰면 사이에 래핑파우더를 개재시켜 주는 것은 물론이다. 이 래핑파우더는 공작물재치대(24)와 나사봉(25)을 관통하는 관통공(24')(25')을 통해 하부로 배출된다.The lapping tool 22 has a shape corresponding to the shape of the lapping work portion of the work piece 35, thereby allowing lapping work. In the lapping operation, of course, the lapping powder is interposed between the workpiece 35 and the friction surface of the lapping tool 22. The wrapping powder is discharged downward through the through holes 24 'and 25' passing through the workpiece holder 24 and the threaded rod 25.

상기와 같은 작동하는 본 고안은 회전식공구에 의해 래핑작업을 할 수 없었던 공작물을 쉽게 가공할 수 있을 뿐만 아니라, 그 구조가 간단하여 제작비가 저렴하며 사용이 간편하여 작업능률을 크게 향상시키는 것등의 특징을 지닌 것이다.This invention works as described above can not only easily process the workpiece that could not be wrapped by the rotary tool, but also because its structure is simple, low production cost and easy to use, greatly improving the work efficiency, etc. It is characteristic.
