Description

절삭톱의 진동방지장치{Tremor Prevention Device Of Cutting Saw}Tremor Prevention Device Of Cutting Saw

본 발명은 절삭톱의 진동방지장치에 관한 것으로, 보다 상세하게는 구동축과 연동하는 절삭톱의 구동구조를 변경하고 진동방지부재를 구비시킴으로써, 구동축이 공회전됨이 없이 회전력을 절삭톱에 정확하게 전달시켜 절삭을 보다 용이하게 하면서 절삭톱의 절삭깊이를 더욱 깊게 형성할 수 있는 것이다.The present invention relates to an anti-vibration device of a cutting saw, and more particularly, by changing the drive structure of the cutting saw interlocked with the drive shaft and providing a vibration preventing member, thereby accurately transmitting the rotational force to the cutting saw without idling the drive shaft. The cutting depth of the cutting saw can be formed deeper while making the cutting easier.

그리고, 상기 절삭톱의 진동이 현저히 감소되어 불안정한 절삭을 방지함으로써, 두께가 얇은 절삭톱과 다이몬드팁의 사용이 용이하고, 이에따라 절삭부하가 현저히 감소되어 절삭의 용이함을 한층 높일 수 있도록 한 것이다.In addition, the vibration of the cutting saw is significantly reduced to prevent unstable cutting, so that the use of a thin cutting saw and a diamond tip is easy, and accordingly, the cutting load is significantly reduced, thereby increasing the ease of cutting.

첨부된 예시도면 도 1 내지 도 3은 일반적으로 도로나 건물 또는 암석등을 절삭하고자 사용되는 절삭장치를 나타낸 것으로, 먼저 절삭장치(10) 하우징(12)의 상면에는 구동모터(14)가 설치되어 있고, 상기 하우징(12)의 일측면에는나선부(16)를 일끝부위에 일부 형성한 구동축(18)이 하우징(12)으로부터 노출되도록 갖추어져 있으며, 이 구동축(18)은 구동모터(14)와 연동하도록 도시되지 않은 체인 또는 밸트로 상호 연결되어 있다.1 to 3 show a cutting device generally used to cut a road, a building, or a rock. First, a driving motor 14 is installed on an upper surface of a housing 12 of a cutting device 10. In addition, one side of the housing 12 is provided with a drive shaft 18 having a part of the spiral portion 16 formed at one end thereof so as to be exposed from the housing 12, the drive shaft 18 and the drive motor 14 and Interconnected by chains or belts not shown to interlock.

또한, 상기 하우징(12)으로부터 노출되는 원형의 구동축(18)상에는 원주를 따라 다수개의 다이아몬드팁(20)을 용접한 절삭톱(22)이 억지끼움으로 끼워져 있고, 이 절삭톱(22)을 중심으로 양편의 구동축(18)에는 절삭톱(22)의 양측면에 각각 밀착되는 한쌍의 플랜지(24)가 상호 압지 고정되도록 볼트(26)로 체결되어 있다.Moreover, on the circular drive shaft 18 exposed from the said housing 12, the cutting saw 22 which welded the several diamond tip 20 along the circumference is inserted by interference fit, and this cutting saw 22 is centered. Thus, a pair of flanges 24 in close contact with both side surfaces of the cutting saw 22 are fastened to the drive shafts 18 on both sides by bolts 26 so as to be mutually press-fixed.

그리고, 상기 플랜지로(24)부터 노출되는 구동축(18)상에는 플랜지(24)를 비롯한 절삭톱(22)의 위치 이동을 방지하고자 고정판(28)이 결합.고정되어 있고, 상기 구동축(18)의 나선부(16)에는 구동축(18)상에 결합된 다수개의 부품이 이탈되지 않도록 너트(30)가 체결되어 있다.In addition, the fixing plate 28 is coupled and fixed on the drive shaft 18 exposed from the flange passage 24 to prevent the positional movement of the cutting saw 22 including the flange 24. The nut 30 is fastened to the spiral portion 16 so that a plurality of parts coupled to the drive shaft 18 are not separated.

한편, 상기 절삭톱(22)의 상부 외측에는 구조물과의 절삭시에 발생되는 절삭가루와 다이아몬드팁(20)의 이탈로 인한 작업자를 보호하고자 절삭톱(22)을 내부에 수용하는 상태로 반원모양의 안전커버(32)가 씌워져 있으며, 이 안전커버(32)의 일측면은 하우징(12)과 용접되어 있다.On the other hand, the upper outer side of the cutting saw 22 has a semi-circular shape in a state that accommodates the cutting saw 22 inside to protect the operator due to the separation of the cutting chips and the diamond tip 20 generated during cutting with the structure The safety cover 32 is covered, and one side of the safety cover 32 is welded to the housing 12.

따라서, 작업자가 절삭장치(10)를 이용하여 암석이나 아스팔트와 같이 단단하고 강한 구조물을 작업설계에 맞게 절삭하면 되는데, 우선 절삭장치(10)의 구동모터(14)를 구동시키게 되면 도시되지않은 체인 또는 밸트에 의해 회전력이 구동축(18)에 전달되어 고속회전하게 된다.Therefore, the operator may cut a hard and strong structure such as rock or asphalt according to the work design by using the cutting device 10. First, when the driving motor 14 of the cutting device 10 is driven, a chain not shown is shown. Alternatively, the rotational force is transmitted to the drive shaft 18 by the belt to rotate at high speed.

그리고, 상기 구동축(18)이 고속회전하게 되면, 구동축(18)상에 억지끼워진 절삭톱(22)과 플랜지(24)가 연동하여 고속회전하게 되는데, 이때 구동축(18)의 회전력은 플랜지(24)에 전달되고, 이 플랜지(24)는 상호 압지력으로 면 밀착된 절삭톱(22)을 연동 회전시키게 되는 것이다.When the drive shaft 18 is rotated at a high speed, the cutting saw 22 and the flange 24 interposed on the drive shaft 18 are rotated at high speed, and the rotational force of the drive shaft 18 is the flange 24. ), The flange 24 is to interlock the cutting saw 22 in close contact with each other by the pressing force.

그러나, 상기와 같이 구성된 종래의 절삭장치(10)를 이용하여 절삭시, 절삭톱(22)과 다이아몬드팁(20)에서 형성되는 절삭부하로 인하여 심한 진동이 발생하면서 절삭이 불안정하게 이루어지는데, 이때 이와 같이 발생되는 절삭부하를 현저히 감소시키고자 절삭톱(22)과 다이아몬드팁(20)의 두께(T,T')를 각각 얇게 형성할 경우, 구조물과의 접촉면이 줄어들어 절삭부하를 감소시킬 수는 있으나, 두께가 얇아진 만큼 절삭톱(22)의 진동이 더욱 심하게 발생하게 되고, 따라서 이를 방지하기 위한 플랜지(24)의 외경이 상대적으로 커져야 됨으로써, 절삭깊이(L)가 현저히 줄어들어 작업성과 편의성이 저하되는 문제점이 있었다.However, when cutting using the conventional cutting device 10 configured as described above, due to the cutting load formed in the cutting saw 22 and the diamond tip 20, severe vibration occurs while cutting is unstable. In order to significantly reduce the cutting load generated as described above, when the thicknesses T and T 'of the cutting saw 22 and the diamond tip 20 are thinly formed, the contact surface with the structure can be reduced to reduce the cutting load. However, as the thickness is thinner, the vibration of the cutting saw 22 is more severely generated, and thus, the outer diameter of the flange 24 is to be relatively increased to prevent this, so that the cutting depth L is significantly reduced, thereby reducing workability and convenience. There was a problem.

한편, 상기 동일 외경(D)을 갖는 절삭톱(22)을 사용하면서 절삭깊이(L)를 길게 하기 위해 플랜지(24)의 외경을 작게 형성할 경우에는 상기 플랜지(24)의 외경이 줄어든 만큼 절삭깊이(L)를 그 이상 깊게 형성할 수는 있다.On the other hand, when the outer diameter of the flange 24 is made small in order to increase the cutting depth L while using the cutting saw 22 having the same outer diameter D, the outer diameter of the flange 24 is cut down. Depth L can be formed deeper.

하지만, 플랜지(24)의 외경이 작아진 만큼 절삭톱(22)과의 면 밀착되는 접촉면이 줄어들어 절삭톱(22)에서 발생되는 진동을 감소시킬 수 없고, 따라서 절삭톱(22)과 다이아몬드팁(20)의 두께(T,T')를 두껍게 형성하여야 하는 문제점이 있었다.However, as the outer diameter of the flange 24 decreases, the contact surface in close contact with the cutting saw 22 decreases, so that the vibration generated in the cutting saw 22 cannot be reduced, and thus the cutting saw 22 and the diamond tip ( 20) there was a problem in that the thickness (T, T ') should be formed thick.

또한, 상기 구동축(18)의 외면과 절삭톱(22)의 관통공(36) 내면은 상호 동일한 원주를 갖는 원형으로 결합되어 있어서, 절삭톱(22)에 절삭부하가 형성되면, 구동축(18)이 관통공(36)에서 공회전을 하면서 회전력 전달이 이루어지지 않아 절삭이 이루어지지 않게 되는 문제점이 있었다.In addition, the outer surface of the drive shaft 18 and the inner surface of the through hole 36 of the cutting saw 22 are coupled in a circular shape having the same circumference, so that when the cutting load is formed on the cutting saw 22, the driving shaft 18 There was a problem that the cutting is not made because the rotational force is not transmitted while idling in the through hole 36.

본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 절삭톱의 진동을 현저히 감소시켜 두께가 얇은 절삭톱 및 다이몬드팁의 사용이 가능하고, 이에따라 절삭부하가 급격히 감소되어 절삭의 용이함을 한층 높일 수 있음은 물론, 구동축의 공회전됨이 없이 회전력을 절삭톱에 정확히 전달하여 불안정한 절삭방지 및 절삭소음을 급격히 감소시키면서 절삭톱의 절삭깊이를 더욱 깊게 형성할 수 있도록 한 것이다.The present invention has been made to solve the above problems, it is possible to significantly reduce the vibration of the cutting saw to use a thin cutting saw and diamond tip, accordingly, the cutting load is sharply reduced to further increase the ease of cutting Of course, it is possible to accurately form the cutting depth of the cutting saw while reducing the unstable cutting prevention and cutting noise by accurately transmitting the rotational force to the cutting saw without idling the drive shaft.

상기와 같은 목적을 달성하기 위한 본 발명은 안전커버의 양측에 고정된 고정부재의 내부에 구동축에 결합된 절삭톱과 다이아몬드팁의 두께를 줄이기 위해 절삭톱의 양측면을 접촉하는 진동방지부재가 각각 갖추어진 구조로서, 절삭톱의 진동을 현저히 감소시켜 두께가 얇은 절삭톱 및 다이몬드팁의 사용이 가능하고, 이에따라 절삭부하가 급격히 감소되어 절삭의 용이함을 한층 높일 수 있음은 물론, 구동축의 공회전됨이 없이 회전력을 절삭톱에 정확히 전달하여 불안정한 절삭방지 및 절삭소음을 급격히 감소시키면서 절삭톱의 절삭깊이를 더욱 깊게 형성할 수 있는점에 특징이 있다.The present invention for achieving the above object is provided with a vibration preventing member in contact with both sides of the cutting saw to reduce the thickness of the cutting saw and the diamond tip coupled to the drive shaft inside the fixed member fixed to both sides of the safety cover, respectively. As the structure, the vibration of the cutting saw is significantly reduced to enable the use of thin cutting saws and diamond tips, and thus the cutting load is drastically reduced to further increase the ease of cutting and without idling the drive shaft. It is characterized in that the cutting depth of the cutting saw can be further deepened by accurately transmitting the rotational force to the cutting saw while drastically reducing unstable cutting and cutting noise.

첨부된 예시도면 도 4 내지 도 6은 본 발명에 따른 절삭톱의 진동방지장치를 나타낸 것으로, 먼저 절삭장치(10)의 하우징(12)에 갖추어지는 구동축(18)의 외면은 직선의 면이 접하는 각면(a)으로 형성되어 있고, 상기 구동축(18)상에 억지끼움되는 절삭톱(22)의 관통공(36) 내면 또한 상기 구동축(18)의 각면(a)과 대응하는 각면(b)으로 형성되어 있으며, 상기 절삭톱(22)의 양측으로 노출되는 구동축(18)상에는 패드(40)가 절삭톱(22)의 양측면에 밀착되도록 각각 결합되어 있다.4 to 6 show an anti-vibration device of a cutting saw according to the present invention. First, the outer surface of the drive shaft 18 provided in the housing 12 of the cutting device 10 is in contact with a straight surface. The inner surface of the through-hole 36 of the cutting saw 22, which is formed on the surface a and is forcibly fitted on the drive shaft 18, also corresponds to the surface b corresponding to the surface a of the drive shaft 18. The pad 40 is coupled to each side of the cutting saw 22 on the driving shaft 18 exposed to both sides of the cutting saw 22.

또한, 상기 패드(40)의 외측에는 구동축(18)으로부터 발생되는 진동이 절삭톱(22)의 전체로 전달되지 않도록 하기 위하여 재질이 동으로 이루어진 한쌍의 진동흡수부재(42)가 각각 끼워져 있다.In addition, a pair of vibration absorbing members 42 each made of copper is fitted to the outside of the pad 40 so that vibration generated from the drive shaft 18 is not transmitted to the entire cutting saw 22.

그리고, 상기 진동흡수부재(42)의 외측에는 패드(40)와 진동흡수부재(42)가 위치 이동되지 않도록 제 1,2고정판(44,46)이 끼워져 있고, 제 2고정판(46)의 외측으로 노출되는 나선부(16)에는 테핑와셔(48)와 스프링와셔(50) 그리고 구동축(18)상에 구비된 각 부품이 이탈되지 않도록 하기 위한 너트(30)가 순차적으로 체결.고정되어 있다.In addition, the first and second fixing plates 44 and 46 are fitted to the outside of the vibration absorbing member 42 so that the pad 40 and the vibration absorbing member 42 are not moved. The spiral portion 16 exposed to the tapped washer 48, the spring washer 50 and the nut 30 for fastening each component provided on the drive shaft 18 is fastened.

또한, 상기 절삭톱(22)의 상부 외측에는 작업자를 보호하고자 안전커버(32)가 씌워져 있는데, 이 안전커버(32)의 양측 내면에는 소정의 면적을 갖는 고정플레이트(52)가 렌치볼트(54)에 의해 각각 체결되어 있다.In addition, the upper outer side of the cutting saw 22 is covered with a safety cover 32 to protect the operator, the fixing plate 52 having a predetermined area on both inner surfaces of the safety cover 32, the wrench bolt 54 Are respectively fastened by

또한, 상기 고정플레이트(52)의 양측 일정위치에는 안전커버(32)의 외측에서 체결되는 렌치볼트(56)에 의해 고정부재(58)가 상호 대응하는 상태로 각각 고정되어 있고, 상기 고정부재(58)의 중앙 내부에는 절삭톱(22)의 양측면을 접촉하는 상태로 회전위치를 가이드하여 진동을 감소시키기 위한 한쌍의 진동방지부재(60)가 각각 갖추어져 있는데, 상기 진동방지부재(60)는 절삭톱(22)의 고속회전에 대한 간섭이 없도록 자유회전 가능한 베어링의 구조를 이루면서 동이나 고무의 재질로 형성된 롤링부(62)로 되어 있다.In addition, the fixing member 58 is fixed to each other at a predetermined position on both sides of the fixing plate 52 in a state in which the fixing members 58 correspond to each other by the wrench bolts 56 fastened from the outside of the safety cover 32, respectively. Inside the center of the 58 is provided with a pair of anti-vibration member 60 for reducing the vibration by guiding the rotational position in contact with both sides of the cutting saw 22, the anti-vibration member 60 is cut Rolling portion 62 formed of a copper or rubber material while forming a structure of a freely rotatable bearing so as not to interfere with the high-speed rotation of the saw 22.

상기와 같이 구성된 본 발명은 작업자가 절삭장치를 이용하여 구조물을 절삭하고자 하는 경우, 첨부된 예시도면 도 1, 도 4 내지 도 6에 도시된 바와 같이 우선, 절삭장치(10)의 구동모터(14)를 구동시켜 구동모터(14)와 연동하는 구동축(18)이 회전하게 되면, 상기 구동축(18)에 끼워진 절삭톱(22)이 고속으로 회전하게 된다.According to the present invention configured as described above, when a worker intends to cut a structure by using a cutting device, as shown in the accompanying drawings, FIGS. 1 and 4 to 6, first, the driving motor 14 of the cutting device 10. When the drive shaft 18 interlocked with the drive motor 14 is rotated by driving), the cutting saw 22 fitted to the drive shaft 18 rotates at a high speed.

이때, 구동축(18)의 외면과 절삭톱(22)의 관통공(36)은 상호 공회전됨이 없도록 각각 각면(a),(b)으로 결합되어 있어서 상기 절삭톱(22)에 절삭부담이 크게 형성되더라도 구동축(18)이 절삭톱(22)의 관통공(36)에서 공회전됨이 없이 회전력을 절삭톱(22)에 정확히 전달시키게 되는 것이다.At this time, the outer surface of the drive shaft 18 and the through hole 36 of the cutting saw 22 are coupled to each of the surfaces (a) and (b) so as not to be mutually idle, so that the cutting burden on the cutting saw 22 is large. Even if it is formed, the drive shaft 18 is to accurately transmit the rotational force to the cutting saw 22 without idling in the through hole 36 of the cutting saw 22.

또한, 상기와 같이 구동축(18)이 절삭톱(22)의 관통공(36)에서 공회전이 방지되면, 종래와 같이 구동축(18)의 회전력을 절삭톱(22)에 전달시키기 위한 매개인 플랜지(24)를 제거할 수 있고, 이에따라 동일 외경(D)을 갖는 절삭톱(22)을 사용할 경우 플랜지(24)가 구비된 절삭깊이(L)는 물론, 플랜지(24)가 제거된 절삭깊이(L') 만큼 더 깊게 형성하여 작업자가 절삭에 대한 작업성과 편의성을 보다 향상시킬 수 있는 것이다.In addition, when the drive shaft 18 is prevented from idling in the through hole 36 of the cutting saw 22 as described above, the flange (which is a medium for transmitting the rotational force of the drive shaft 18 to the cutting saw 22 as in the prior art) 24 can be removed and accordingly, when using the cutting saw 22 having the same outer diameter D, the cutting depth L with the flange 24 as well as the cutting depth L with the flange 24 removed It can be formed as deep as') so that the operator can improve the workability and convenience for cutting.

한편, 구조물과의 절삭시에는 구동축(18)과 절삭톱(22)에서 심한진동 및 절삭소음이 발생되는데, 이때 절삭톱(22) 양측의 구동축(18)상에는 한쌍을 이루는 패드(40)와 진동흡수부재(42)가 각각 끼워져 있어서, 상기와 같이 발생되는 진동을 패드(40)와 재질이 동으로 이루어진 진동흡수부재(42)가 각각 흡수하게 된다.On the other hand, when cutting with the structure, severe vibration and noise are generated in the drive shaft 18 and the cutting saw 22, in which the pair of pads 40 and vibration on the drive shaft 18 on both sides of the cutting saw 22 Absorbing members 42 are fitted, respectively, the vibration absorbing member 42 is made of a copper material and the pad 40, the vibration generated as described above, respectively.

그리고, 상기 진동을 진동흡수부재(42)가 흡수하게 되면, 절삭톱(22)의 전체로 진동이 전달되는 것을 방지하게 되고, 이에따라 그에 수반되는 절삭소음이 감소되어 정숙한 절삭을 유도함은 물론, 보다 용이한 구조물의 절삭을 이룰 수 있는 것이다.In addition, when the vibration absorbing member 42 absorbs the vibration, the vibration is prevented from being transmitted to the entire cutting saw 22. Accordingly, the cutting noise accompanying the vibration is reduced to induce a quiet cutting. It will be easier to cut the structure.

또한, 상기와 같이 절삭중에는 절삭부하가 증가할 수록 절삭톱(22)의 진동이 심하게 발생되는데, 이때 안전커버(32)의 양측면에는 절삭톱(22)의 양측면을 접촉하는 상태로 진동방지부재(60)가 각각 갖추어져 있는데, 상기 진동방지부재(60)는 절삭톱(22)의 고속회전에 간섭이 없도록하고자 베어링의 구조를 갖는 롤링부(62)로 이루어져 있다.In addition, as the cutting load increases as the cutting load increases as described above, vibration of the cutting saw 22 is severely generated. At this time, both sides of the safety cover 32 are in contact with both sides of the cutting saw 22. 60 is provided, respectively, the vibration preventing member 60 is composed of a rolling portion 62 having a structure of a bearing so as not to interfere with the high-speed rotation of the cutting saw 22.

상기 롤링부(62)는 절삭톱(22)의 고속회전과 접촉하는 상태로 연동하면서 회전위치를 가이드함으로써, 절삭톱(22)의 진동을 방지하고, 그에 따른 절삭능력을극대화시켜 보다 용이한 절삭을 이룰 수 있는 것이다.The rolling unit 62 guides the rotational position while interlocking in contact with the high-speed rotation of the cutting saw 22, thereby preventing vibration of the cutting saw 22 and maximizing the cutting capacity accordingly, thereby making cutting easier. Can be achieved.

또한, 상기 롤링부(62)에 의해 절삭톱(22)의 진동이 현저히 감소되면, 보다 두께(t,t')가 얇은 절삭톱(22)과 다이몬드팁(20)의 사용이 용이하고, 이에 따라 상기 두께(t,t')가 각각 줄어든 만큼 절삭부하가 현저히 감소되어 구조물의 용이한 절삭과 절삭능력을 한층 높일 수 있음은 물론, 상기 절삭톱(22)과 다이몬드팁(20)의 두께(t,t')가 각각 얇아진 만큼 제작상에 원가절감 및 단가를 낮출 수 있어 경제적인 것이다.In addition, when the vibration of the cutting saw 22 is significantly reduced by the rolling portion 62, the use of the cutting saw 22 and the diamond tip 20 having a thinner thickness (t, t ') is easy. As the thickness (t, t ') is reduced, the cutting load is significantly reduced, so that the cutting and cutting ability of the structure can be further increased, as well as the thickness of the cutting saw 22 and the diamond tip 20 As t and t ') become thinner, it is economical because it can reduce cost and unit cost in production.

위와 같이 본 발명은 구동축과 연동하는 절삭톱의 구동구조를 변경하여 구동축과 절삭톱에서 발생되는 진동을 현저히 감소시킴으로써, 보다 두께가 얇은 절삭톱과 다이아몬드팁의 사용이 용이하고, 이에따라 절삭부하가 현저히 감소되어 절삭의 용이함을 한층 높일 수 있음은 물론, 절삭소음을 현저히 줄일 수 있으며, 아울러 절삭톱에 절삭부하가 크게 형성되더라도 상호 공회전됨이 없이 회전력을 정확히 전달시키면서 절삭톱의 절삭깊이를 더욱 깊게 형성할 수 있는 효과가 있다.As described above, the present invention changes the drive structure of the cutting saw interlocking with the drive shaft to significantly reduce the vibration generated in the drive shaft and the cutting saw, thereby making it easier to use a thinner cutting saw and diamond tip, thereby significantly reducing the cutting load. It can be reduced to further increase the ease of cutting, and can significantly reduce the cutting noise. Furthermore, even if the cutting load is largely formed on the cutting saw, the cutting depth of the cutting saw can be formed deeper while accurately transmitting the rotational force without mutual idling. It can work.

그리고, 상기와 같이 보다 두께가 얇은 절삭톱과 다이아몬드팁을 사용이 용이함으로써, 절삭톱의 제작에 따른 원가절감 및 단가를 현저히 낮출 수 있어 경제적인 효과를 얻을 수 있는 것이다.In addition, by using a thinner cutting saw and a diamond tip as described above, it is possible to significantly reduce the cost and unit cost according to the production of the cutting saw to obtain an economic effect.
