Description

샤시 절단기Chassis cutter

본 발명은 샤시 절단기에 관한 것으로서 더욱 상세히 설명하면, 절단기의 승강 및 회전이 가능하여 피 절단물의 절단 깊이나 절단각도 등을 용이하게 조절할 수 있도록 한 샤시 절단기에 관한 것이다.The present invention relates to a chassis cutter, which will be described in more detail. The present invention relates to a chassis cutter capable of easily raising and rotating the cutter to easily adjust the cutting depth or cutting angle of the workpiece.

절단기는 각종 샤시나 형강 등을 일정길이로 절단하는 것으로서 종래의 일반적인 절단기는 예시도 1과 같이 전원을 이용하는 모우터(1)에 의해 회전톱날(2)이 회전되어 지지대(3) 상에 안치된 피 가공물을 가공하도록 되어 있었으며, 작업시에는 작업손잡이(4)를 앞으로 당김으로서 전후 이동봉(5)에 의해 전후 이동판(6)이 기대(7)상에서 전방으로 이동할 수 있도록 되어 있었다.The cutting machine is to cut various chassis, section steel, etc. to a certain length, the conventional general cutting machine is rotated by the motor (1) using a power source as shown in Figure 1 rotates the saw blade (2) is placed on the support (3) In order to process the workpiece, the front and rear moving plates 6 were moved forward on the base 7 by the front and rear moving rods 5 by pulling the work handle 4 forward during the work.

상기와 같은 종래의 절단기는 지지대에 안치된 피 가공물을 단순히 절단할 수만 있었으므로 피 가공물을 사선 방향으로 절단한다던지 일정 깊이로 절단하고자 할 때는 별도의 지지대나 받침대를 사용하여야 하므로 시간이 많이 소요되고 동일한 제품을 다수 절단 가공하고자 할 때는 작업도중에 작업환경이 바뀌어 동일한 제품 가공이 곤란한 결점이 있었다.The conventional cutter as described above was able to simply cut the workpiece placed in the support, so when cutting the workpiece diagonally or to cut to a certain depth, a separate support or pedestal should be used, which takes a lot of time. When trying to cut and cut many of the same products, the working environment changed during the work, which made it difficult to process the same products.

본 발명은 상기와 같은 종래의 절단기가 갖는 제반 결점을 해결하기 위한 것으로서 전후 이동판의 일측 하부에 각도 조정기를 설치하여 회전톱날의 각도를 변경시킬 수 있도록 하며, 힌지축을 중심으로 톱날의 높이를 변경시킬 수 있도록 하고 회전원판을 중심으로 절단기 전체가 회전되어 피 가공물의 절단 각도를 임의로 변화시킬 수 있도록 함에 목적이 있다.The present invention is to solve the above-mentioned shortcomings of the conventional cutter as described above to install an angle adjuster on one side lower portion of the front and rear moving plate to change the angle of the rotary saw blade, and change the height of the saw blade around the hinge axis The purpose of the present invention is to allow the cutting machine to be rotated around the rotating disc and to arbitrarily change the cutting angle of the workpiece.

상기와 같은 목적을 실현하기 위한 본 발명은 기대상에 전후 이동판을 설치하여 회전톱날을 전후로 이동시킬 수 있도록 한 것에 있어서, 힌지축을 중심으로 승강판이 승강되어 회전톱날을 승강시킬 수 있도록 하고, 각도 조정기에 의해 전후 이동판의 각도를 변경시켜 회전톱날의 각도(피 가공물의 상하 절단각도)를 변경시킬 수 있도록 하며, 회전원판을 중심으로 회전원판과 함께 절단기 전체가 회전되어 지지대와 회전톱날의 각도를 변화시키도록 함으로서 가공물의 좌우 절단각도를 임의로 변경시킬 수 있도록 한 것이다.The present invention for realizing the above object is to install the front and rear moving plate on the base to move the rotary saw blade forward and backward, the lifting plate is lifted around the hinge axis to allow the rotary saw blade to elevate, the angle By adjusting the angle of the front and rear moving plate by the adjuster, it is possible to change the angle of the saw blade (up and down cutting angle of the workpiece). It is to be able to arbitrarily change the left and right cutting angle of the workpiece by changing the.

본 발명을 첨부된 예시도면과 함께 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.

본 발명은 회전톱날(2)이 설치된 전후 이동판(6)을 기대(7)상에서 전후로 이동시킬 수 있도록 된 것에 있어서, 모우터(1)와 회전톱날(2)을 승강판(8)에 설치하고 전후 이동판(6)상에서 승강판(8)을 힌지축(9)으로 결합하여 승강핸들(10)을 회전시켜 승강판(8)을 승강시키도록 하며, 전후 이동판(6)의 일측 하부에는 각도조정기(11)를 설치하여 웜기어(12)를 회전시킴으로서 전후 이동판(6)의 각도를 변경시킬 수 있도록 하고, 각도조정기(11)와 일체로 결합된 회전원판(13)을 기대(7) 상에서 회전시킬 수 있도록 한 것이다.In the present invention, it is possible to move the front and rear moving plate 6 provided with the rotary saw blade 2 back and forth on the base 7, and the motor 1 and the rotary saw blade 2 are installed on the elevating plate 8. Then, the elevating plate 8 is coupled to the hinge shaft 9 on the front and rear moving plate 6 to rotate the elevating handle 10 to elevate and elevate the elevating plate 8. In order to rotate the worm gear 12 by installing an angle adjuster 11 so that the angle of the front and rear moving plate 6 can be changed, and the rotation disc 13 integrally coupled with the angle adjuster 11 is expected (7 ) So that it can rotate on

승강핸들(10)은 나사봉 형태로 구성되어 시계방향 또는 반시계방향으로 돌리게 되면 너트형태로 되어 있는 결합부(14)에 의해 힌지축(9)을 중심으로 승강판(8)이 부채꼴 형태로 승강된다. 따라서 승강판(8)에 일체로 결합되어 있는 모우터(1) 및 회전톱날(2)도 하강 높이가 변경되므로 지지대(3) 상에 안치된 피 가공물의 절단깊이가 달라지게 된다.The lifting handle 10 is configured in the form of a screw rod, and when turned clockwise or counterclockwise, the lifting plate 8 has a fan shape centering on the hinge shaft 9 by a coupling portion 14 that is in the form of a nut. It is elevated. Therefore, since the lowering height of the motor 1 and the rotary saw blade 2 which are integrally coupled to the elevating plate 8 are changed, the cutting depth of the workpiece placed on the support 3 is changed.

각도 조정기(11)의 일측은 회전원판(13)에 보울트(15)로 결합되어 있으며, 조정기 핸들(16)을 회전시키면 웜기어(12)가 회전되고, 이에따라 웜기어 축(17)도 회전되는데, 상기 웜기어 축(17)의 회전각도만큼 전후 이동판(6)도 일체로 회전되어 결국 회전톱날(2)의 각도가 비스듬히 변경되는 것이다.One side of the angle adjuster 11 is coupled to the rotation disk 13 with the bolt 15, and when the adjuster handle 16 is rotated, the worm gear 12 is rotated, accordingly, the worm gear shaft 17 is also rotated, The front and rear moving plate 6 is also integrally rotated as much as the rotation angle of the worm gear shaft 17 so that the angle of the rotary saw blade 2 is changed obliquely.

웜기어 축(17)에는 키이(18)가 결합되어 헛돌음을 방지하고, 웜기어 축(17)의 일측에는 조임너트(19)를 고정봉(20)으로 조여서 작업시에 웜기어(12)의 떨림현상이나 풀림현상을 방지하도록 되어 있다.The key 18 is coupled to the worm gear shaft 17 to prevent loosening, and on one side of the worm gear shaft 17, the tightening nut 19 is tightened with the fixing rod 20 to shake the worm gear 12 during operation. Or to prevent loosening.

각도 조정기(11)에 의해 회전톱날(2)의 각도를 조정함으로서 피 가공물을 수직방향 또는 사선방향으로 절단할 수 있게 된다.By adjusting the angle of the rotary saw blade 2 by the angle adjuster 11, the workpiece can be cut in the vertical direction or the diagonal direction.

회전원판(13)에는 중앙의 원형천공부(21)에 연하여 톱날 가이드홈(22)이 형성되어 있고, 일측에 회전손잡이(23)가 형성되어 있으며, 하부에는 고정부(24)와 베어링(25)이 결합되어 임의로 회전시킬 수 있도록 되어 있다.The rotary disk 13 has a saw blade guide groove 22 formed in connection with the central circular drilling portion 21, the rotary knob 23 is formed on one side, the fixing portion 24 and the bearing ( 25) is combined to rotate arbitrarily.

따라서 회전 손잡이(23)를 잡고 회전원판(13)을 회전시키면 회전원판(13)과 함께 각도 조정기(11)와 전후 이동판(6) 및 승강판(8)등이 동시에 회전된다.Accordingly, when the rotary disc 13 is rotated by holding the rotary knob 23, the angle adjuster 11, the front and rear moving plate 6, the elevating plate 8, and the like are simultaneously rotated together with the rotary disc 13.

또한 회전원판(13)에는 원호형 요홈(26)과 눈금(27)이 형성되어 있고 원호형 요홈(26)에는 고정너트(28)가 관통되도록 하여 작업시에 회전원판(13)을 고정하도록 되어 있다.In addition, an arc-shaped groove 26 and a scale 27 are formed in the rotating disk 13, and a fixing nut 28 is penetrated through the arc-shaped groove 26 to fix the rotating disk 13 at the time of work. have.

지지대(3)는 중앙부위를 하방으로 절곡하여 원형천공부(12)를 관통한 후 고정부(24)에 결합하도록 되어 있다.The support 3 is bent downward to penetrate the central portion and penetrate the circular hole 12, and is then coupled to the fixed portion 24.

따라서 회전원판(13)을 돌리더라도 지지대(3)는 기대(7)와 함께 일정상태로 고정되어 있게 되는 것이다.Therefore, even if the rotary disk 13 is rotated, the support 3 is fixed in a constant state with the base 7.

회전원판(13)을 회전시켜 고정너트(28)로 고정한 후 피 가공물을 절단하게 되면 피 가공물에 대하여 회전톱날(2)이 좌우 방향으로 회전된 상태를 유지하게 되어 일정각도로 절단이 가능하게 된다.After rotating the rotating disc 13 and fixing the workpiece by fixing the fixing nut 28, the rotary saw blade 2 is rotated in the horizontal direction with respect to the workpiece to be cut at a predetermined angle. .

본 발명은 힌지축(9)을 중심으로 승강판(8)과 함께 회전톱날(2)을 승강 시킴으로서 피 가공물의 절단 깊이를 임의로 변경시킬 수 있고, 각도 조정기(11)에 의하여 전후 이동판(6) 및 승강판(8)의 각도를 웜기어 축(17)을 중심으로 변경시킬 수 있으며, 회전원판(13)을 회전시킬 수 있도록 함으로서 피 가공물의 좌우 절단각도를 변경시킬 수 있어서 빠른시간내에 정확한 가공을 할 수 있는 효과가 있다.The present invention can arbitrarily change the cutting depth of the workpiece by elevating the rotary saw blade (2) together with the elevating plate (8) around the hinge axis (9), and by the angle adjuster 11 back and forth moving plate (6) ) And the elevating plate 8 can be changed about the worm gear shaft 17, and the rotating disc 13 can be rotated to change the left and right cutting angles of the workpiece so that accurate machining can be performed quickly. There is an effect that can be done.
