Description

가이드 레이저 장치를 구비한 휴대용 컷소Portable cut saw with guide laser device
본 발명은 컷소 전동공구에 관한 것으로, 더욱 상세하게는 파이프나 목재 등의 절단 대상물의 표면에 절단할 방향을 가이드 하는 라인 레이저를 조사함으로써 작업자가 정확하고 편리하게 원하는 각도로 절단 대상물을 절단할 수 있도록 하는 휴대용 컷소에 관한 것이다.The present invention relates to a cut-so power tool, and more particularly, by irradiating a line laser for guiding the cutting direction on the surface of a cutting object such as a pipe or wood, the operator can accurately and conveniently cut the cutting object at a desired angle. It is related to a portable cut saw.
휴대용 전동공구는 내장된 배터리 또는 외부에서 공급되는 전원에 의하여 작동되는 모터가 케이스 내부에 장착되고, 모터의 회전축으로부터 연장된 공구장착용 소켓에 드릴, 드라이버, 그라인더 또는 톱날 등의 각종 공구를 장착한 구조로 이루어진다.The portable power tool is equipped with a motor operated by a built-in battery or an externally supplied power source inside the case, and various tools such as a drill, a screwdriver, a grinder or a saw blade are mounted in a tool mounting socket extending from the rotating shaft of the motor. Made of structure.
휴대용 전동공구는 휴대가 간편하여 전원이 공급되는 곳이면 장소에 상관없이 드릴, 드라이버, 그라인더 또는 절삭 작업을 편리하게 수행할 수 있는 장점이 있다. 특히 충전식 배터리가 내장되어 있는 경우에는 전원이 공급되지 않는 곳이거나, 전원공급용 연장케이블을 설치하여 사용하기에는 작업공간의 구조가 복잡하거나 층별로 이동하며 작업해야 하기 때문에 작업성이 좋지 않은 곳에서도 쉽게 사용할 수 있기 때문에 최근에는 다양한 충전식 휴대용 전동공구가 소개되고 있다.Portable power tools are easy to carry and have the advantage of being able to conveniently perform drills, drivers, grinders or cutting operations wherever power is supplied. In particular, when a rechargeable battery is built in, it is not easy to operate in places where power is not supplied, or because the structure of the work space is complicated to install and use an extension cable for power supply, or work must be done by floor. Recently, various rechargeable portable power tools have been introduced.
이러한 휴대용 전동공구 중 전동식 톱인 컷소(cut saw)는 장착된 톱날을 모터로 직선 왕복운동시켜 파이프나 목재 등을 원하는 길이나 형태로 자르는 전동공구로 널리 사용되고 있다.Among these portable power tools, a cut saw, which is an electric saw, is widely used as a power tool for cutting a pipe or wood into a desired length or shape by linearly reciprocating a mounted saw blade with a motor.
그런데 컷소 중에서 휴대용 컷소는 손으로 직접 들고 절단 작업을 하는 소형 전동공구인데, 절단방향이 전적으로 작업자의 손놀림에 달려 있기 때문에 절단된 작업품의 품질에 편차가 생기기 쉽고 불량이 발생할 가능성 또한 높다.By the way, the portable cut-saw is a small power tool that is cut and held by hand, and the cutting direction is entirely dependent on the operator's hand.
이러한 휴대용 컷소의 절단품질을 향상시키기 위해서는 절단 대상물에 미리 선을 그어 표시를 하는 것이 좋지만 일일이 이런 재단 작업을 미리 준비하는 것은 상당히 번거로운 일이다.In order to improve the cutting quality of such a portable cut saw, it is recommended to mark the cutting object in advance, but it is cumbersome to prepare such cutting work in advance.
이러한 불편함을 해소하고자 한국공개특허 제2014-0000535호의 "레이저 직선계가 설치된 전동공구"가 제안된 바 있는데, 이 전동공구는 회전톱 또는 전동톱의 톱날이 가리키는 톱날의 길이 방향과 동일한 직선상에 레이저빔을 조사하여 작업자가 이 레이저빔을 따라 절단하도록 가이드 함으로써 절단 대상물을 일직선으로 정확하게 자를 수 있도록 도움을 주는 것이다.In order to solve this inconvenience, Korean Patent Laid-Open Publication No. 2014-0000535 has proposed a power tool with a laser linear system installed on a straight line in the length direction of a saw blade indicated by a saw blade of a rotary saw or chainsaw. By irradiating the laser beam and guiding the worker to cut along the laser beam, it helps to cut the cutting object in a straight line.
위와 같은 종래의 컷소(전동톱)는 따로 선을 그어 재단하는 작업을 줄여줬다는 점에서 상당히 유용한 기술이지만, 단지 절단 대상물을 일직선으로 자를 수 있도록 도움을 줄뿐 이 직선이 원하는 방향, 예를 들면 파이프나 목재를 모서리에 대해 45°각도로 자르도록 유도할 수는 없다는 한계를 가진다. Conventional cut saws (power saws) are a very useful technique in that they reduce the work of cutting by cutting lines, but they only help to cut the cutting object in a straight line. The limitation is that the wood cannot be induced to cut at an angle of 45 ° to the edge.
따라서, 본 발명의 목적은 작업자가 휴대용 컷소로 절단 대상물을 일직선으로 정확히 자를 수 있도록 하는 것은 물론 원하는 방향(각도)으로 자를 수 있도록 하는 휴대용 컷소를 제공함에 있는 것이다.Accordingly, an object of the present invention is to provide a portable cut saw that allows the operator to cut the cutting object in a straight line with a portable cut saw as well as to cut in the desired direction (angle).
본 발명은 내장된 모터의 구동으로 직선 왕복운동을 톱날이 장착되는 컷소에 있어서, 상기 톱날 주변에 구비되고, 상기 톱날이 가리키는 톱날의 길이 방향과 동일한 직선상에 레이저빔을 조사하는 제1 라인 레이저; 및 상기 제1 라인 레이저가 조사하는 레이저빔에 대한 각도가 가변 조절되는 레이저빔을 조사하는 제2 라인 레이저;를 포함한다.The present invention relates to a cut saw in which a saw blade is mounted in a linear reciprocating motion by driving a built-in motor, the first line laser being provided around the saw blade and irradiating a laser beam on a straight line identical to the longitudinal direction of the saw blade indicated by the saw blade. ; And a second line laser that irradiates a laser beam in which an angle of the laser beam irradiated by the first line laser is variably adjusted.
본 발명의 실시형태에 따라서는, 상기 제2 라인 레이저가 조사하는 레이저빔은 상기 제1 라인 레이저가 조사하는 레이저빔에 대해 0∼90°각도의 범위에서 가변 조절될 수 있다.According to the embodiment of the present invention, the laser beam irradiated by the second line laser may be variably adjusted in the range of 0 to 90 ° with respect to the laser beam irradiated by the first line laser.
그리고, 상기 제2 라인 레이저가 조사하는 레이저빔의 각도를 조절하는 조작수단 및 상기 각도를 표시하는 표시수단을 구비하는 것이 바람직하다.In addition, it is preferable to include an operation means for adjusting the angle of the laser beam irradiated by the second line laser and a display means for displaying the angle.
또한, 상기 제1 라인 레이저가 조사하는 레이저빔과 상기 제2 라인 레이저가 조사하는 레이저빔은 그 색상이 서로 다르도록 구성될 수도 있다.In addition, the laser beam irradiated by the first line laser and the laser beam irradiated by the second line laser may be configured to have different colors.
본 발명의 휴대용 전동공구는 종래와 같이 톱날이 가리키는 톱날의 길이 방향과 동일한 직선상에 레이저빔을 조사하는 제1 라인 레이저를 구비하는 것은 물론 제1 라인 레이저의 레이저빔에 대해 각도가 가변되는 제2 라인 레이저의 레이저빔을 기준선으로 사용하도록 함으로써 종래의 휴대용 컷소에서는 불가능하였던 원하는 각도로 자르는 작업이 가능해진다.The portable power tool of the present invention includes a first line laser that irradiates a laser beam on a straight line that is the same as the saw blade's longitudinal direction, as well as a conventional variable angle with respect to the laser beam of the first line laser. By using the laser beam of the two-line laser as a reference line, it is possible to cut at a desired angle, which was not possible in the conventional portable cut saw.

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시형태에 대하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명의 실시형태를 설명함에 있어서 당업자라면 자명하게 이해할 수 있는 공지의 구성에 대한 설명은 본 발명의 요지를 흐리지 않도록 생략될 것이다. 또한 도면을 참조할 때에는 도면에 도시된 선들의 두께나 구성요소의 크기 등이 설명의 명료성과 편의상 과장되게 도시되어 있을 수 있음을 고려하여야 한다.In describing the embodiments of the present invention, descriptions of well-known configurations that will be obvious to those skilled in the art will be omitted so as not to obscure the subject matter of the present invention. In addition, when referring to the drawings it should be considered that the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.
도 1은 본 발명에 따른 휴대용 컷소(10)의 전체적인 구조를 도시한 도면인데, 이를 참조하여 본 발명을 상세히 설명한다.1 is a view showing the overall structure of a portable cut saw 10 according to the present invention, with reference to this will be described in detail the present invention.
본 발명은 내장된 모터의 구동으로 직선 왕복운동을 톱날(12)이 장착되는 컷소(10)에 관한 것인데, 특히 컷소(10)의 톱날(12) 방향을 가이드 하기 위한 두 개의 라인 레이저를 구비하고 있는 것에 특징이 있다. 여기서 라인 레이저란 레이저 광이 점이 아닌 선으로 나타나는 레이저를 말하는 것으로서, 측량분야에서 사용되는 수준기 등에 이미 널리 사용되고 있는 공지기술이므로 이에 대한 상세한 설명은 생략한다. 또한, 라인 레이저를 만들기 위한 레이저 다이오드나 구동 드라이버, 렌즈 등의 구성도 공지된 기술인바 이에 대한 설명도 본 발명의 요지를 흐리지 않기 위해 생략하기로 한다.The present invention relates to a cut saw 10 in which a saw blade 12 is mounted in a linear reciprocating motion by driving an embedded motor. In particular, the present invention includes two line lasers for guiding the saw blade 12 direction of the cut saw 10. There is a characteristic to being. Here, the line laser refers to a laser in which the laser light is represented by a line instead of a point, and since it is a well-known technique already widely used in a level level used in the field of surveying, detailed description thereof will be omitted. In addition, a configuration of a laser diode, a driving driver, a lens, etc. for making a line laser is also a well-known technique, and a description thereof will be omitted in order not to obscure the subject matter of the present invention.
먼저 본 발명에 구비되는 첫 번째 라인 레이저는 톱날(12) 주변에 구비되어 톱날(12)이 가리키는 톱날(12)의 길이 방향과 동일한 직선상에 레이저빔을 조사하는 제1 라인 레이저(100)다. 제1 라인 레이저(100)는 톱날(12)이 진행해야 할 가상의 절단방향을 가시화하기 위한 레이저로서, 작업자는 제1 라인 레이저(100)에서 조사되는 직선의 레이저빔을 따라 톱날(12)을 이동시킴으로써 자르는 선이 휘어지거나 비뚤어지지 않고 똑바로 진행하도록 가이드 해준다.First, the first line laser provided in the present invention is a first line laser 100 provided around the saw blade 12 to irradiate the laser beam on a straight line that is the same as the longitudinal direction of the saw blade 12 indicated by the saw blade 12. . The first line laser 100 is a laser for visualizing a virtual cutting direction to which the saw blade 12 should proceed, and the operator moves the saw blade 12 along a straight laser beam irradiated from the first line laser 100. By moving, the cutting line guides you straight ahead without bending or skewing.
즉, 작업자는 제1 라인 레이저(100)의 레이저빔을 따라 톱날(12)을 이동시키는 동시에 이미 잘라진 선과 레이저빔을 일치시킴으로써 절단선이 계속 일직선을 이루도록 하면서 작업을 하게 되고, 이에 따라 전체 절단선이 일직선을 이루도록 할 수 있는 것이다.That is, the worker works by moving the saw blade 12 along the laser beam of the first line laser 100 while simultaneously matching the already cut line with the laser beam so that the cutting line continues to be in a straight line. This can be done in a straight line.
그리고, 두 번째 라인 레이저는 제1 라인 레이저(100) 주변에 구비되고, 제1 라인 레이저(100)가 조사하는 레이저빔에 대한 각도가 가변 조절되는 레이저빔을 방출하는 제2 라인 레이저(200)이다. 제1 라인 레이저(100)는 톱날(12)의 길이 방향과 동일한 직선상에 레이저빔을 조사해야 하기 때문에 그 조사방향이 변하면 안 된다. 이에 비해 제2 라인 레이저(200)는 직선의 레이저빔의 방향이 제1 라인 레이저(100)의 고정된 조사방향에 대해 가변될 수 있는 것이다.The second line laser is provided around the first line laser 100, and the second line laser 200 emits a laser beam in which an angle with respect to the laser beam emitted by the first line laser 100 is variably adjusted. to be. Since the first line laser 100 must irradiate the laser beam on the same straight line as the longitudinal direction of the saw blade 12, the irradiation direction should not be changed. In contrast, the direction of the straight line laser beam of the second line laser 200 may vary with respect to the fixed irradiation direction of the first line laser 100.
여기서, 제2 라인 레이저(200)의 레이저빔은 톱날(12)의 진행방향을 지시하기 위한 것이 아니며, 절단 대상물에 대해 제1 라인 레이저(100)의 레이저빔을 원하는 각도로 설정하기 위한 기준선을 제공하기 위한 것이다.Here, the laser beam of the second line laser 200 is not intended to indicate the direction in which the saw blade 12 travels, and a reference line for setting the laser beam of the first line laser 100 at a desired angle with respect to the cutting object. It is to provide.
이는 도 2를 참조하면 좀더 명확히 이해될 수 있는데, 제2 라인 레이저(200)에서 조사된 레이저빔(제2 라인 레이저의 도면부호인 '200'으로 표시)을 절단 대상물의 모서리에 맞춤으로써 이를 기준선으로 삼고, 제2 라인 레이저(200)의 레이저빔에 대해 일정 각도를 형성하는 제1 라인 레이저(100)의 레이저빔(제1 라인 레이저의 도면부호인 '100'으로 표시)을 따라 톱날(12)로 똑바로 절단하면 제1/제2 라인 레이저(100,200)의 레이저빔 사이의 각도대로 절단 대상물이 잘라지게 된다. 즉, 제2 라인 레이저(200)의 레이저빔이 제1 라인 레이저(100)의 레이저빔에 대해 이루는 각도를 원하는 값으로 조절하면 그 조절된 각도대로 절단 대상물을 자를 수 있는 것이다. This can be more clearly understood with reference to FIG. 2, by adjusting the laser beam (indicated by '200', which is a symbol of the second line laser) irradiated from the second line laser 200 to a corner of the cutting object. And saw blade 12 along the laser beam (denoted by '100', which is the reference for the first line laser) of the first line laser 100, which forms an angle with respect to the laser beam of the second line laser 200. Cutting straight with) cuts the cutting object at an angle between the laser beams of the first and second line lasers 100 and 200. That is, if the angle formed by the laser beam of the second line laser 200 with respect to the laser beam of the first line laser 100 is adjusted to a desired value, the cutting object may be cut at the adjusted angle.
제2 라인 레이저(200)의 각도를 조절하는 방법은 다양하게 만들어질 수 있는데, 예를 들면 제2 라인 레이저(200)의 광학계 내지는 렌즈 자체를 회전노브(하기의 조작수단에 해당)로 돌릴 수 있는 회전식으로 만들어서 각도를 변경할 수 있게 하고, 제2 라인 레이저(200)의 외주면을 따라 현재의 각도를 표시(하기의 표시수단에 해당)하여 수동으로 원하는 각도로 세팅할 수 있을 것이다.The method of adjusting the angle of the second line laser 200 may be made in various ways. For example, the optical system or the lens itself of the second line laser 200 may be rotated by a rotary knob (corresponding to the following operation means). It is possible to change the angle by making the rotary, and to display the current angle (corresponding to the display means below) along the outer circumferential surface of the second line laser 200 may be manually set to the desired angle.
이외에도, 제2 라인 레이저(200)의 레이저빔 각도를 조절하는 조작수단(210)을 스테핑 모터로 광학계를 회전시키는 전동식으로 만들고, 디지털 방식으로 각도를 표시하는 표시수단(220)을 구비하는 형태로 만드는 것도 가능하다.In addition, the control means 210 for adjusting the laser beam angle of the second line laser 200 is made electric by rotating the optical system with a stepping motor, and has a display means 220 for displaying the angle digitally. It is also possible to make.
한편, 도 1에서 설명되지 않은 도면부호 '230'은 제1/제2 라인 레이저(100,200)의 작동을 온/오프시키기 위한 레이저 작동버튼을 표시한 것이다.Meanwhile, reference numeral 230 not illustrated in FIG. 1 indicates a laser operation button for turning on / off the operation of the first and second line lasers 100 and 200.
본 발명의 실시형태에 따라서는, 제2 라인 레이저(200)가 조사하는 레이저빔이 제1 라인 레이저(100)가 조사하는 레이저빔에 대해 0∼90°각도의 범위에서 가변 조절되도록 만들 수 있다. 이는 90°를 넘어서는 각도는 절단 방향을 반대로 바꾸면 되기 때문이다. According to the exemplary embodiment of the present invention, the laser beam irradiated by the second line laser 200 may be adjusted in a range of 0 to 90 ° with respect to the laser beam irradiated by the first line laser 100. . This is because an angle exceeding 90 ° may be reversed in the cutting direction.
또한, 통상적으로 가장 많이 사용되는 각도인 0°, 30°, 45°, 60°, 90°의 다섯 각도로만 전환되도록 설정하여 놓는 것도 효과적일 수 있으며, 대안적으로 15°각도 간격으로 조절되도록 만드는 것도 바람직할 수 있다.In addition, it can be effective to set only five angles, 0 °, 30 °, 45 °, 60 °, and 90 °, which are the most commonly used angles. It may also be desirable.
그리고, 제1/제2 라인 레이저(100,200)가 조사하는 레이저빔의 색상은 동일하거나 또는 서로 다를 수 있는데, 특히 제1/제2 라인 레이저(100,200)가 조사하는 레이저빔의 색상을 서로 다르게, 예를 들면 제1 라인 레이저(100)는 적색이고 제2 라인 레이저(200)는 녹색으로 서로 다르게 구성함으로써 작업자가 혼동을 일으키지 않고 절단선을 지시하는 제1 라인 레이저(100)의 레이저빔을 정확하게 인식하고 집중할 수 있도록 하는 것도 바람직할 수 있다.The colors of the laser beams irradiated by the first and second line lasers 100 and 200 may be the same or different. In particular, the colors of the laser beams irradiated by the first and second line lasers 100 and 200 are different from each other. For example, the first line laser 100 is red and the second line laser 200 is configured differently in green so that the laser beam of the first line laser 100 instructing the cutting line without causing confusion for the operator can be accurately identified. It may be desirable to be able to recognize and focus.
