제4도에는 본 발명의 기계톱의 헤드부(10)의 상세단면도가 도시되어 있으며, 헤드부(10)는 직사각형으로 쇠톱 구동부(12)의 상,하 미끄럼부재(33,33')가 슬라이딩할 수 있도록 상하단에 2개의 축(13)을 고정하는 견부(14)를 지닌다. 미끄럼부재(33') 하방의 축(13)상에는 스프링(34)이 구비된다. 또 구동축(11)의 한단부에는 돌기축(30)과 돌기축에 관해 회전가능한 베어링(31)을 구비한 크랭크부(15)가 설치되고, 구동축(11)의 회전에 따라 크랭크부(15)가 회전하도록 되어 있다. 그리고, 쇠톱 구동부(12)의 후면에는 쇠톱 구동부의 길이 방향과 수직인 적절한 길이의 장홈(32)을 구비한 작동자(16)가 고착되고, 제6도에 도시된 바와같이 크랭크부(15)의 베어링(31)은 이 장홈(32)을 적절히 따르게 되어 있다. 따라서, 모터(2)의 구동에 의해 구동축(11)이 회전되고, 이 회전에 의해 크랭크부(15)의 베어링(31)이 작동자(16)의 장홈(32)을 따라 회전하므로 쇠톱 구동부(12)를 상하 운동시킨다.4 is a detailed cross-sectional view of the head portion 10 of the machine saw of the present invention, the head portion 10 is a rectangular shape, the upper and lower sliding members (33, 33 ') of the hacksaw drive unit 12 can slide. It has a shoulder 14 for fixing the two shafts 13 on the upper and lower ends. A spring 34 is provided on the shaft 13 below the sliding member 33 '. One end of the drive shaft 11 is provided with a crank portion 15 having a projection shaft 30 and a bearing 31 rotatable about the projection shaft, and the crank portion 15 as the drive shaft 11 rotates. Is supposed to rotate. Then, the operator 16 having the long groove 32 of the appropriate length perpendicular to the longitudinal direction of the hacksaw drive unit is fixed to the rear surface of the hacksaw drive unit 12, and the crank unit 15 as shown in FIG. Bearing 31 is to follow this long groove (32) appropriately. Accordingly, the drive shaft 11 is rotated by the driving of the motor 2, and the bearing 31 of the crank part 15 rotates along the long groove 32 of the operator 16 by this rotation. 12) up and down exercise.

구동축(11)은 허브(17)속에서 회전가능하게 삽입되어 있고, 허브(17)는 브라켓(18)에 의해서 기계톱의 베드(1) 위에 고정되어 있다. 한편 헤드부(10)는 헤드부(17)에 대해 회전가능하며 필요에 따라서 헤드부(10)를 임의의 각도로, 예를들어 30°로 회전하여 헤드부(10)의 후면에 설치된 홈(21)에 허브(17)를 관통하는 각도 고정 볼트(22)를 체결하여 고정시킬 수 있다. 한편, 쇠톱 구동부(12)는 쇠톱을 고정시킬 수 있는 지지부(19)를 지닌다.The drive shaft 11 is rotatably inserted in the hub 17, and the hub 17 is fixed on the bed 1 of the machine saw by the bracket 18. On the other hand, the head portion 10 is rotatable with respect to the head portion 17 and, if necessary, rotates the head portion 10 at an arbitrary angle, for example, 30 ° to provide a groove provided at the rear of the head portion 10 ( 21 may be fixed by fastening the angle fixing bolt 22 penetrating the hub 17. On the other hand, the hacksaw driver 12 has a support 19 for fixing the hacksaw.

다시 제1도를 참조하면, 본 발명의 기계톱의 클램핑부(20)가 베드(1)의 우측에 도시되는데 이것은 슬라이드 테이블(23) 및 회전 스위벨(Swivel)(24)위에 설치된다.Referring again to FIG. 1, the clamping portion 20 of the machine saw of the present invention is shown on the right side of the bed 1, which is mounted on a slide table 23 and a rotating swivel 24.

제5도에는 클램핑부의 상세단면도가 도시되는데 슬라이드 테이블(23)은 핸들(25)의 회전에 의해서 헤드부로 전진한다. 슬라이드 테이블(23)에 고정된 회전 수위벨(24)은 그위에 설치된 클램핑부(20)가 헤드부(10)에 설치된 쇠톱과 일정각을 유지하도록 회전되고 고정된다. 클램핑부(20)는 작업물을 제5도의 X축 방향으로 고정시키는 바이스 형태이나 본 발명의 기계톱에서는 작업물을 정밀하게 전달할 수 있도록 브라켓(26)에서 연장된 돌출부(27)에 고정부(28)를 설치하여 작업물을 Y축 방향으로도 고정시키게 한다.5 is a detailed cross-sectional view of the clamping part, in which the slide table 23 is advanced to the head part by the rotation of the handle 25. The rotating water level bell 24 fixed to the slide table 23 is rotated and fixed so that the clamping portion 20 installed thereon maintains a constant angle with the hacksaw installed on the head portion 10. The clamping portion 20 is in the form of a vice to fix the workpiece in the X-axis direction of FIG. 5, but in the machine saw of the present invention, the fixing portion 28 is provided on the protrusion 27 extending from the bracket 26 so as to precisely transfer the workpiece. ) So that the workpiece is also fixed in the Y-axis direction.

본 발명의 기계톱을 작동시키려면 스위치(29)를 넣어 모터(2)에 전원을 넣으며 모터(2)가 구동되고 그 회전력이 모터(2)의 회전풀리(5) → 감속기(6)의 입력풀리(7) → 감속기(6)의 출력풀리(8) → 헤드부(10)의 구동축(11)의 구동풀리(9) → 구동축(11) → 크랭크부(15)의 베어링(31), 작동자(16)의 장홈(32)으로 연결되어 쇠톱 구동부(12)가 상하로 이동되고 쇠톱도 상하로 작동된다.In order to operate the chain saw of the present invention, the power is supplied to the motor 2 by inserting a switch 29, the motor 2 is driven and the rotational force of the rotation pulley 5 of the motor 2 → the input pulley of the reducer 6 (7) → output pulley (8) of reducer (6) → drive pulley (9) of drive shaft (11) of head (10) → drive shaft (11) → bearing (31) of crank section (15), operator Connected to the long groove 32 of 16, the hacksaw drive unit 12 is moved up and down, and the hacksaw is also operated up and down.

다음에는 클램핑부(20)에 고정된 작업물이 필요한 각도로 유지되어 슬라이드 테이블(23)에 의해서 쇠톱을 향하여 전진하면 작업물이 전달되기 시작한다. 한편, 작업물을 특정 각도로 절단시키기 위해서는 헤드부(10)를 임의 각도로 경사지게하여 헤드부(10)의 허브(17)를 중심으로 회전시켜 필요한 작업을 행할 수 있다. 이때에는 헤드부(10)의 후면에 설치된 홈(21)과 일정각도, 예를들면 30°떨어진 다른 홈에 허브(17)를 관통하는 각도 고정 볼트(22)를 이전하여 고정시키므로써 가능하다.Next, the workpiece fixed to the clamping portion 20 is maintained at the required angle and advances toward the hacksaw by the slide table 23 and the workpiece starts to be delivered. On the other hand, in order to cut the workpiece at a specific angle, the head portion 10 can be inclined at an arbitrary angle and rotated around the hub 17 of the head portion 10 to perform the necessary work. In this case, it is possible to transfer and fix the angle fixing bolt 22 penetrating the hub 17 to another groove at a predetermined angle, for example, 30 ° away from the groove 21 installed on the rear of the head portion 10.

상기와 같이 구성된 본 발명의 기계톱은 작업물의 형상에 관계없이 모든 강 및 비철금속의 박판을 180°내에서 임의 각도로 기계 전달할 수 있게하며 종래와 같이 수작업으로 가공했을때 보다 시간이 단축되고 가공면이 정밀하다. 또한, 본 발명의 기계톱은 경량이므로 이동이 용이하다.The machine saw of the present invention configured as described above enables the machine to transfer all steel and nonferrous metal sheets at any angle within 180 ° irrespective of the shape of the workpiece. Precise In addition, the machine saw of the present invention is lightweight and easy to move.

본 발명의 기계톱에 사용되는 공구인 쇠톱은 기존상품인 10인치 또는 12인치 쇠톱으로 시중에서 구입하여 사용하므로 쇠톱의 교체와 구매에도 편리하다. 더우기, 본 발명의 기계톱의 클램핑부는 유공압 장치를 설치하여 자동으로 작업물을 고정시키게 변형 가능하다.Hacksaw which is a tool used in the machine saw of the present invention is convenient to replace and purchase a hacksaw because it is purchased on the market as a conventional 10-inch or 12-inch hacksaw. Furthermore, the clamping part of the machine saw of the present invention can be modified to automatically fix the workpiece by installing a pneumatic device.
