[고안의 상세한 설명][Detailed Description of Design]

본 고안은 작업자가 안전한 상태에서 양질의 장축을 단시간에 연삭할 수 있게 함을 목적으로 하는 보통 선반에서의 장축연삭장치에 관한 것이다.The present invention relates to a long axis grinding device in a normal lathe for the purpose of allowing the operator to grind a good long axis in a short time in a safe state.

종래축의 길이가 길어(3000mm이상) 연삭기에서 연삭을 할 수 없는 장축의 연삭 가공 방법은 선반에서 장축을 선삭한 후, 제4도에 도시한 바와 같이 샌드 페이퍼(A=)를 축 외주연에 감싸서 손으로 파지 한 다음 축을 회전시켜 연삭하는 것으로 이는 연삭이라기 보다 연마정도에 그치며, 1차 선삭된 축의 외경을 일정하고 정확한 가공 치수로 연삭하기는 어렵고 가공된 외주면의 표면 거칠기가 거칠게 되며, 연삭기간이 길어 작업자로 하여금 피로 증감으로 인하여 생산성이 저하되었다.The grinding method of the long axis, which cannot be ground in a grinding machine because the length of conventional shaft is longer (more than 3000mm), after turning the long axis on the lathe, as shown in FIG. 4, the sand paper (A =) Grinding by hand and then rotating the shaft is more grinding than grinding. It is difficult to grind the outer diameter of the first-turned shaft to a constant and accurate working dimension, and the surface roughness of the machined outer circumferential surface is rough. As a result, the productivity was reduced due to fatigue by the worker.

또한 고 숙련공이 아니면 질 저하 및 안전사고 위험에 항상 따르는 결점과 폐단이 있었다.There were also shortcomings and shortcomings that were always accompanied by deterioration of quality and risk of safety accidents.

본 고안은 이와 같은 문제점을 해소하기 위하여 안출한 것으로 이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a problem and will be described in detail with reference to the accompanying drawings.

고정판(2)이 하부에 형성된 몸체(1)후측에 풀리(3)를 장착한 모타(4)를 착설하고, 타측 몸체(1)에 횡으로 축(5)을 가설하여 풀리(3')를 장착하고 벨트식 샌드페이퍼(6)를 양풀리(3)(3')에 걸어 끼우고, 집진기(7)와 자바라식 호수(8)로 연결된 커버(9)를 설치하고, 고정판(2)을 선반(10)의 왕복대(1)에 설치된 크로스슬라이드(12) 면상에 볼트(13)로 고정하도록 된 것이다.A motor 4 having a pulley 3 mounted thereon is installed on the rear side of the body 1 having the fixed plate 2 formed thereon, and a shaft 5 is laid horizontally on the other body 1 to pull the pulley 3 '. The belt type sandpaper (6) to the sheep pulley (3) (3 '), install the cover (9) connected with the dust collector (7) and the bellows lake (8), and the fixed plate (2) It is to be fixed with a bolt 13 on the surface of the cross slide 12 provided in the carriage 1 of (10).

이러한 본 고안의 연삭장치는 공구대(14)를 떼어낸 다음 크로스 슬라이드(12)에 장착하여 사용하는 것이다.The grinding device of the present invention is to remove the tool post 14 and then mounted on the cross slide 12 to use.

도면중 미설명 부호(15)는 장축, (16)은 새들(17)은 심압대, (18)은 주축대, (19)는 척, (20)은 세로 이송 핸들(21)은 왕복대 핸들이다.In the drawings, reference numeral 15 denotes a long shaft, 16 a saddle 17 a tailstock, 18 a main shaft, 19 a chuck, and 20 a vertical feed handle 21 a carriage handle. to be.

작동에 있어서 상술한 바와 같이 선반(10)의 왕복대(11)에 본 고안의 장치를 장착하고 척(19)과 심압대(17)사이에 장축(15)을 수평으로 설치한 다음, 장축(15)에 벨트식 샌드페이퍼(6)가 당접되도록 세로 이송 핸들(19)로써 크로스슬라이드(12)상에 장착된 연삭장치를 이동시킨다.In operation, as described above, the device of the present invention is mounted on the carriage 11 of the shelf 10, and the long axis 15 is horizontally installed between the chuck 19 and the tailstock 17, and then the long axis ( The grinding device mounted on the cross slide 12 is moved by the longitudinal transfer handle 19 so that the belt-type sandpaper 6 is brought into contact with 15).

주축을 구동으로 장축(15)을 회전 시킴과 동시에 장축(15)의 회전 방향과 반대 방향으로 모타(4)를 구동시켜 벨트식 샌드 페이퍼(6)를 회전 시키면 장축(15)외주면이 연삭되는 것이다.The outer peripheral surface of the long shaft 15 is ground by rotating the belt sand paper 6 by driving the motor 4 in a direction opposite to the rotation direction of the long shaft 15 while simultaneously rotating the long shaft 15 by the main shaft. .

이때 왕복대(11)를 일정 속도로 이동시키면서 연삭하면 장축(15)외주면은 원하는 표면 거칠기 상태로 진원도를 얻을 수 있으며 또한 방진구를 사용하지 않고도 가공공차 범위내의 외경으로 연삭할 수 있는 것이다.At this time, when grinding while moving the carriage 11 at a constant speed, the outer circumferential surface of the long axis 15 can obtain the roundness in the desired surface roughness state and can be ground to the outer diameter within the processing tolerance range without using a dustproof hole.

또한 커버(9)에 자바라식 호스(8)로서 연결된 집진기(7)를 설치하였으므로 연삭할 때 발생되는 분진가루를 흡수 하므로서 외부로 유출되는 것을 방지하여 작업자의 건강을 해치지 않도록 하였다.In addition, since the dust collector (7) connected to the cover (9) as a bellows type hose (8) is installed, it prevents the outflow to the outside by absorbing the dust generated when grinding so as not to harm the health of the worker.

따라서 본 고안은 상술한 바와 같은 효과외에도 제조공정이 단순하고, 장축(15)뿐 만 아니라 단축의 표면연삭을 손쉽게 할 수 있으며, 미숙련공에 의해서도 단시간내에 정확하고 안전한 작업이 가능할 뿐 아니라 가공시간을 단축할 수 있는 동시에 수공작업으로 인한 안전사고 위험을 방지할 수 있으며 보통 선반의 기능을 좀더 다양한 용도로 사용할 수 있는 효과있는 고안인 것이다.Therefore, the present invention, in addition to the effects described above, the manufacturing process is simple, not only the long axis (15) but also the surface of the short axis can be easily, not only the unskilled workers can be precise and safe work in a short time, but also reduce the processing time At the same time, it is possible to prevent the risk of safety accidents caused by manual work, and it is an effective design that can use the functions of the shelf for more various purposes.
