본 고안은 컴퓨터 수치제어(CNC)기능을 가지는 탁상용 드릴(Bench Drilling M/C)에 적합하도록 공작물 제치용 테이블의 위치가 전, 후 이송과 자전 동작 할 수 있도록 구성된 CNC탁상용 드릴의 테이블 자전 및 이송 장치에 관한 것이다.The present invention is to rotate and feed the table of the CNC table drill, which is configured for the position of the workpiece placing table to be moved forward and backward and rotated to be suitable for the bench drill with computer numerical control (CNC) function. Relates to a device.

탁상용 드릴은 그 형태 및 조작 방법의 특성상 중소 기업이나 대형 공장를 막론하고 가장 널리 본급 사용되고 있는 기계 가동 장치의 하나이다.The table drill is one of the most widely used machine-moving devices in small and medium-sized enterprises and large factories due to its shape and operation method.

그런데, 이들은 공히 피절삭될 공작물을 제치 고정시켜 주는 테이블의 붙박이식으로 고정 설치되어 있으므로 해서, 테이블상에 장착되는 피가공물의 최대크기가 스핀들로 부터 몸체 지지대까지로 제한되고 있으며, 용도 또한 단순한 구멍 절삭 가공뿐이며, 공작물의 각도 분할(Angular Indexing)등의 기능이 없어서 작업자가 일일이 수작업으로 분할 천공함에 따라 그 가공 위치와 간격이 정확하게 일치하지 않는 등의 문제점이 있었다.By the way, since they are fixedly installed in a table that fixes the workpiece to be cut, the maximum size of the workpiece to be mounted on the table is limited from the spindle to the body support. There is only a cutting process, there is no function such as angular indexing of the workpiece, there is a problem such that the machining position and the interval does not exactly match as the operator separates and drills manually by hand.

또한, 최근 선반(Lathe)업게 에서는 컴퓨터를 이용한 수치제어 방식을 도입하여 3차원 절삭과 함께 보다 정확한 가공과 자동 제어 가능한 CNC 선반을 양산하고 있는 실정이다.In addition, the lathe industry recently introduced a numerical control method using a computer to mass produce CNC lathes that can be processed more accurately and automatically with 3D cutting.

따라서, 본 고안은 종래의 위와 같은 탁사용 드릴의 구조 및 기능상의 문제점을 해결함과 동시, CNC 기능을 접목시켜 구멍의 자동 절삭과 각도 분할 등의 다기능을 부여함에 따라, 공작물 재치용 테이블을 그에 상용한 전, 후 이송과 자전 동작토록 함을 목적으로 안출 제공된 것이다.Therefore, the present invention solves the structure and functional problems of the conventional table drill as described above, and at the same time, by combining the CNC function to give a multi-function, such as automatic cutting of the hole and angular splitting, the workpiece mounting table It is provided for the purpose of transport and rotation operation before and after commercial use.

이하에서 이를 첨부된 도면을 따라 상세히 설명하면 다음과 같다.Hereinafter, this will be described in detail with reference to the accompanying drawings.

하단에 지지용 받침대(4)가, 상단에는 스핀들과 드릴(2)등이 내설된 몸체(1)가 고정 설치된 주축(3)의 일측에 공작물 재치용 테이블(5)을 설치함에 있어서, 도면 제3도에서와 같이, 일측면이 개방된 상태에서, 상면 중앙부에 베드(61) 및 저면에 볼 술라이드홈(62)을 구비하였고, 내측면 상부에 랙(Rack)(63)이 고정 부착된 소정 길이의 ㄷ 형 안내대(6)가 후단의 결합부(64)를 이용하여 상기 주축(3)의 일측에 고정 결합 설치되었다.In installing the table 5 for mounting the workpiece on one side of the main shaft 3 on which the support pedestal 4 is attached at the lower end, and the body 1 on which the spindle and the drill 2 are installed is fixed at the upper end. As shown in FIG. 3, with one side open, a bed 61 at the center of the upper surface and a ball suicide groove 62 are provided at the bottom, and a rack 63 is fixedly attached to the upper side of the inner side. The c-shaped guide 6 of a predetermined length was fixedly installed on one side of the main shaft 3 by using the coupling portion 64 of the rear end.

그리고, 내부 공간의 상부에는 상기 베드(61)와 형합될 슬라이딩홈(71)과 하부에는 상기 안내대(6)저면의 볼슬라이드홈(62)내로 삽입될 볼 베어링(73)을 구비한 지지대(72)가 부설된 4각 틀체형의 전후 이송체(7)가 상기 안내대(6)외측방으로 슬라이딩 자재토록 삽입 결합 설치됨과 동시에, 전후 이송체(7)저면의 브래킷트(74)에 고정된 전후 이송용 모우터(9)의 선단에는 구동기어(91) 및 감속기어(10)가 연동 치합되었다.A support having a sliding groove 71 to be fitted with the bed 61 at the upper portion of the inner space and a ball bearing 73 to be inserted into the ball slide groove 62 at the bottom of the guide 6 at the lower portion thereof. The front and rear conveying body 7 of the quadrangular frame shape in which 72 is installed is inserted and installed so as to slide outward of the guide 6 and is fixed to the bracket 74 at the bottom of the front and rear conveying body 7. The drive gear 91 and the reduction gear 10 are interlocked with each other at the front end of the forward and backward transfer motor 9.

그리고, 전후 이송체(7)의 측면을 관통하고서 개방부를 통해 안내대(6)내에 위치하는 종동축(8)의 후단에는 상기 랙(63)과 치합된 피니언(82)이, 선단에는 상기 감속기어(10)와 치합된 종동기어(81)가 각각 고정 설치되었다.In addition, a pinion 82 engaged with the rack 63 is provided at the rear end of the driven shaft 8 positioned in the guide 6 through the opening portion through the front and rear conveying body 7, and the deceleration at the front end thereof. The driven gear 81 meshed with the gear 10 was fixedly installed, respectively.

또한, 원판형 테이블(5)의 저면 외측방으로는 원형 내기어 (51)가 고정부착되었고, 그 내측으로는 보다 작은 외경을 가지는 받침판(12)이 볼베어링(13)을 계재시킨 상태로 회전 자재토록 설치되었으며, 상기 받침판(12)의 저면과 전후 이송체(7)의 상면이 볼트부재(도시하지 않음)로서 상호 견고하게 체결 설치되었다.In addition, a circular inner gear 51 is fixedly attached to the outer side of the bottom surface of the disk-shaped table 5, and the supporting plate 12 having a smaller outer diameter is rotated in the state in which the ball bearing 13 is engaged. The bottom surface of the supporting plate 12 and the top surface of the front and rear conveying body 7 were firmly installed as bolt members (not shown).

그리고, 전후 이송체(7)의 일측면에는 브래킷트(75)를 이용하여 상기 테이블(5)저면의 내기어(51)와 치합회전 동작시킬 피니언(111)을 구비한 자전용 모우터(11)가 고정 설치된 것이며, 도면중 미 설명부호 14는 입력된 자료를 바탕으로 상기 테이블(5)을 전후 이송 내지 자전 동작시킬 CNC 콘트롤러이다.In addition, the motor 11 having a pinion 111 which is engaged with the inner gear 51 of the bottom of the table 5 by using a bracket 75 on one side of the front and rear conveying member 7. ) Is fixedly installed, and reference numeral 14 in the drawing is a CNC controller to operate the table 5 forward and backward or rotate based on the input data.

이상과 같이 구성된 본 고안은, 하방의 전후 이송용 모우터(9)를 정 또는 역방향으로 구동시키게 되면, 그 동력이 구동기어(91)-감속기어(10)를 통해 알맞은 속도로 감속된뒤, 종동기어 (81)-종동촉(8)-피니언(82)으로 전달되므로서, 피니언(82)이 랙(63)과 치합 이송됨에 따라 상부에 테이블(5)이 설치된 전후 이성체(7)가 안내대(6)상의 베드(61)와 볼 슬라이드홈(62)내로 삽입된 지지대(72)상의 볼 베어링(73)을 이용하여 일정 속도로 전후진 이송 동작되는 것이며, 측방의 자전용 모우터(11)를 정 또는 역방향으로 구동시키면 피니언(111)이 내기어(51)와 치합 회전시킴에 따라 받침판(12)상의 재치된 테이블(5)이 볼 베어링(13)에 의해 일정 속도록 정, 역 방향으로 자전되는 것이다.The present invention configured as described above, when driving the forward and backward transport motor 9 in the forward or reverse direction, the power is decelerated at a suitable speed through the drive gear 91-the reduction gear 10, As it is transferred to the driven gear (81)-driven head (8)-pinion (82), as the pinion (82) is engaged with the rack (63), the front and rear isomers (7) with the table (5) installed on the upper part are guided. By using the ball bearing 73 on the support base 72 inserted into the bed 61 on the base 6 and the ball slide groove 62, forward and backward conveying operation is carried out at a constant speed, and the side motor 11 Drive in the forward or reverse direction, the pinion 111 is engaged with the inner gear 51 and the mounted table 5 on the support plate 12 is rotated by the ball bearing 13 in the forward and reverse directions. To be rotated.

따라서, 이를 상기 CNC콘트롤러(14)와 연결시키게 되면, 전후 이송체(7)가 전후진 내지 테이블이 자전동작 하면서, 그 위에 얹힌 피가공물에 드릴이 하강하여 사전 설계치대로 정확한 위치에 구멍을 가공하게 되는 것이며, 각도 분할 기능도 가지게 되는 것이다.Therefore, when it is connected to the CNC controller 14, while the front and rear conveying body 7 is rotated forward and backward or the table rotates, the drill is lowered to the workpiece placed thereon to process the hole at the correct position according to the pre-designed value. It will also have an angular split function.

이상과 같이 구성되고 작동되는 본 고안은, 테이블이 종래의 위치 고정 방식에서 전후 이송과 자전 기능을 가지게 되므로서, 피가공물의 최대 크기를 스핀들에서 주축(3)까지로 제한되던 종래의 구성보다 최개 2배 까지 확대시킬 수 있으며, 각도 분할 (Index)기능이 부가됨에 따라 구멍 가공 작업을 보다 정확하고 균일하게 행하게 되면서 가공제품의 규격화와 품질 향상에 기여함은 물론이고, 탁상 드릴링 머신의 다 기능화에 따른 이용도 제고와 품질 향상의 특출한 효과가 있는 것이다.The present invention is constructed and operated as described above, since the table has forward and backward feed and rotation functions in a conventional position fixing method, the maximum size of the workpiece is more recent than the conventional configuration in which the maximum size of the workpiece is limited from the spindle to the spindle 3. It can be enlarged up to 2 times, and the addition of the angle division function makes the hole cutting work more accurate and uniform, contributing to the standardization and quality improvement of the processed products, and to the multifunctionalization of the table drilling machine. According to the present invention, there is an outstanding effect of improving quality and improving quality.
