Description

유압식 자동선반의 오버커팅 장치{The equipment over cutting of hydraulic type automatic lathe}Overcutting device for hydraulic automatic lathes {The equipment over cutting of hydraulic type automatic lathe}

본고안은 각종 공작물(비철금속봉,육각,니플)의 외주를 나사가공하는데In this paper, the outer periphery of various workpieces (non-ferrous metal rods, hexagons, nipples) is screwed.

사용하는 유압식자동선반의 오버커팅 장치에 관한것으로서, 더욱 상세하게는The over-cutting device of the hydraulic automatic lathe used, more specifically

선반의 주축대에 동심원으로 '3'개소의 오버커터를 고정설치하여 콜렛척에The over-cutter of '3' is fixed to the collet chuck by concentric circles on the main shaft of the lathe.

물린 공작물의 외주면을 탭핑하도록 된 오버커팅 장치에 관한것이다.The overcutting device is adapted to tap the outer circumferential surface of the bite workpiece.

일반적으로 공작물 외주에 나사를 가공하는데 사용하는 오버커터Overcutter, usually used to machine threads around the workpiece

는 주축대의 상부측에 '1'개소만 설치되어 오버커터 선단의 커터날을Is installed on the upper side of the main shaft only '1' place the cutter blade

유압실린더의 작동으로 진퇴작동시켜 공작물의 외주에 접촉시킨 상태에서With the hydraulic cylinder acting forward and backward, in contact with the outer circumference of the workpiece

모터의 구동에 의한 스핀들의 회전으로 콜렛척에 물려있는 공작물 외주를Rotation of the spindle driven by the motor drives the workpiece outer periphery

나사가공 하도록 되어있다.It is designed to be screwed.

그런데 이러한 종래의 오버커터는 공작물을 주축대와 심압대의 고정센터However, such a conventional over-cutter is the fixed center of the spindle headstock and tailstock

사이에 위치시킨 상태에서 주축대와 고정센터가 공작물의 양단부를 압박Headstock and fixed center press both ends of workpiece

토록 하여 공작물을 고정시킨후 상기 오버커터를 공작물 외주에 접촉시켜To fix the workpiece and contact the outer cutter with the outer periphery

나사가공 할때 오버커터 선단의 커터날이 공작물의 중심축과 일치하지 않When threading, the cutter blade at the tip of the over cutter does not coincide with the central axis of the workpiece.

고 어긋나게 되면 오버커터로 가공된 공작물의 나사부가 동심으로If it is misaligned, the thread of the workpiece machined by the overcutter

가공되지 않게 됨으로써 나사불량이 나게되고 이로인해 오버커터의 커터날을 공작물의 중심축에 맞추어야 하는 수정이 필요하게 되므로 번거로움과 불Not being machined will result in poor threading, which will require the need to correct the cutter edge of the overcutter to the center axis of the workpiece.

편이 따르게 되었을뿐 아니라 이로인해 두세번의 가공공정을 거쳐야만 하는Not only was it accompanied, but it also had to go through two or three

문제점이 있었다.There was a problem.

이에 본고안은 종래 오버커팅 장치의 상기문제점을 해소하기 위해 안출한In order to solve the above problems of the conventional overcut device

것으로서,As,

공작물에 정확한 나사가공을 할수 있도록 함과 동시에 두세번의 가공공정Two or three machining processes while ensuring accurate threading of workpieces

을 한공정으로 마칠수 있도록한 오버커팅 장치를 제공함에 그목적이Its purpose is to provide an over-cutting device that allows you to finish

있는것이다.It is.

상기 목적을 달성하기 위한 본고안은 선반의 주축대상에 동심원으로 '3'In order to achieve the above object, '3' is concentric with the main axis of lathe.

개소의 오버커터를 고정설치하고 앞쪽 선단에는 커터날을 설치하며 오Fix the over cutter at the point and install the cutter blade at the front end.

버커터 후방에는 오버커터를 진퇴작동시키기 위한 유압실린더를 포함한 구성Behind the buck cutter includes a hydraulic cylinder for moving the over cutter back and forth
