본 고안은 원형기계톱에 관한 것으로서, 보다 구체적으로는 피절단물을 향하여 전동식으로 회전되는 원형톱날을 더블링크식으로 동작되도록 함으로서 원형톱날의 절단범위를 신장시켜 주어 비교적 크기가 큰 피절단물도 쉽게 절단할 수 있도록 한 것이다.The present invention relates to a circular machine saw, and more specifically, to operate the circular saw blade rotated toward the cutting object in a double link type to extend the cutting range of the circular saw blade to easily cut a relatively large cut object. It is to be done.
종래의 것은 제1도에 도시된 바와같이 전 동식원형톱날(100)이 베이스(101)의 후방에서 상방향으로 연장되는 고정아암(102)에 축(103)으로 단순히 지지된 것이기 때문에 절단범위가 축(103)을 기점으로 하여 만들어지는 궤적(t)에 의해 한정되어 일정범위내의 크기를 갖는 피절단물 밖에는 절단할 수 없었던 문제점이 있었다.In the related art, since the circular circular saw blade 100 is simply supported by the shaft 103 on the fixed arm 102 extending upward from the rear of the base 101, as shown in FIG. There was a problem that only a cut object having a size within a predetermined range limited by the trajectory t made from the axis 103 as a starting point could be cut.
본 고안의 목적은 원형톱날의 절단범위를 신장시켜서 크기가 비교적 큰 피가공물도 쉽게 절단할 수 있도록 된 원형기계톱을 제공하는데 있다.It is an object of the present invention to provide a circular sawing machine which can easily cut a workpiece having a relatively large size by extending the cutting range of the circular saw blade.
본 고안은 이와같은 목적을 달성하기 위하여 고정아암으로부터의 신장정도와 각도가 조절가능한 작동아암을 구비하여서 된 것인바, 본 고안을 이하 예시도면에 의하여 더욱 상세히 설명하면 다음과 같다.In order to achieve the above object, the present invention is provided with an operating arm having an adjustable extension angle and an angle from the fixed arm. The present invention is described in more detail by the following drawings.
본 고안은 제2도에 예시된 바와같이 원형톱날(1)이 커버(2)로 감싸여진체 하우징(3)에 내장되는 구동모터(4)에 의해 회전되도록 된 것에 있어서, 베이스(5)의 후방에서 상방향으로 연장되는 고정아암(6)과 작동아암(7)에 의해서 지지되어 있으며 베이스(5)의 양측에는 피절단물의 가이드(8)(8′)이 세워져 있고, 이 가이드(8)(8′)에는 조임용 나비볼트(9)(9′)를 포함하는 클램프(10)(10′)가 끼워져 있으며 베이스(5)의 중앙에는 통상의 각도조정핸들(11)이 마련되어 있다.The present invention is designed such that the circular saw blade 1 is rotated by a drive motor 4 embedded in the body housing 3 enclosed by the cover 2 as illustrated in FIG. It is supported by a fixed arm 6 and an operating arm 7 extending upward from the rear, and guides 8 and 8 'of the cutting object are erected on both sides of the base 5, and the guide 8 Clamps 10 and 10 'including the fastening butterfly bolts 9 and 9' are fitted in 8 ', and a normal angle adjusting handle 11 is provided in the center of the base 5.
고정아암(6)의 상,하단부에는 원형지지체(6-1)(6-2)가 마련되어 있으며, 이 고정아암(6)에는 작동아암(7)이 끼워져 있다. 작동아암(7)은 상기 고정아암(6)의 원형지지체(6-1)(6-2)내로 삽입될 수 있도록 된 원형지지체(7-1)(7-2)를 갖고 있으며, 이 원형지지체(7-1)(7-2)내에는 한쌍의 반원형 클러치(12)(12′)가 압축코일스프링(13)(13′)으로 탄석되어 있다.Circular supports 6-1 and 6-2 are provided at the upper and lower ends of the fixed arm 6, and the working arm 7 is fitted to the fixed arm 6. The working arm 7 has circular supports 7-1 and 7-2 which can be inserted into the circular supports 6-1 and 6-2 of the fixed arm 6, which are circular supports. In (7-1) (7-2), a pair of semi-circular clutches 12 (12 ') are charcoaled by compression coil springs 13 (13').
상기 고정아암(6)의 상단부에 있는 원형지지체(6-1)는 구체적으로 제5도에 상세히 표현된 바와같이 작동아암(7)을 90° 각도로 절곡시켜 줄 수 있도록 절반가량이 절개된 작동아암(7)의 각도조절수단을 이루고 있다.The circular support 6-1 at the upper end of the fixed arm 6 is cut in half to allow the operating arm 7 to be bent at a 90 ° angle, as shown in detail in FIG. The angle adjusting means of the arm 7 is achieved.
다시말해서 작동아암(7) 전체는 고정아암(6)으로부터 길이가 신장될 수 있도록 되어 있음과 아울러 한쪽끝이 고정아암(6)에 지지된 상태에서 각도 또한 조절될 수 있도록 된 것이다.In other words, the entire working arm 7 can be extended from the fixed arm 6 and the angle can be adjusted while one end is supported by the fixed arm 6.
이와 같이 구성된 본 고안은 제3도에 예시된 바와 같이 고정아암(6)내에 작동아암(7)이 완전한 삽입지지된 상태에는 보통크기의 피절단물을 절단할 수 있는 것이고, 피절단물의 크기가 클 경우에는 고정아암(6)으로부터 작동아암(7)을 제4도에 예시된 바와 같이 신장시켜 준 다음 제6도에 예시된 바와 같이 고정아암(6)의 상단부에 위치하는 원형지지체(6-1)를 중심으로 하여서 작동아암(7)을 절곡시키면서 큰 피절단물(W)을 절단하는 것이고, 피절단물(W)을 깊숙히 절단할 때는 제7도에 예시된 바와 같이 원형톱날(1)이 지지되는 헤드(h)를 후진시키면 작동아암(7)내의 클러치(12′)의 직경이 스프링(13)을 압축시키면서 작아지게 되어 원형지지체(7-2)를 벗어나면서 슬라이딩되는 것이므로 절단할 수 있게 된다. 이때의 동작상태는 제8도에 구체적으로 표현된 바와 같다.The present invention configured as described above is capable of cutting a medium-sized cutting object while the working arm 7 is fully inserted and supported in the fixed arm 6, as illustrated in FIG. If it is large, extend the working arm 7 from the fixed arm 6 as illustrated in FIG. 4 and then place a circular support 6-positioned at the upper end of the fixed arm 6 as illustrated in FIG. 1) is to cut the large cutting object (W) while bending the operating arm (7) around the center, the circular saw blade (1) as illustrated in FIG. When the supported head h is retracted, the diameter of the clutch 12 'in the operating arm 7 becomes smaller while compressing the spring 13, so that it is slid out of the circular support 7-2. Will be. The operation state at this time is as specifically expressed in FIG.
이와 같이 본 고안은 전동식 원형톱날이 축설된 헤드를 고정아암과 작동아암으로 절단범위를 신장시켜 줄 수 있기 때문에 보통크기의 피절단물은 물론 크기가 큰 피절단물도 절단해 낼 수 있는 것이다.As such, the present invention can extend the cutting range of the head having the electric circular saw blade built into the fixed arm and the working arm, thereby cutting not only a large-sized cut material but also a large cut material.
