Abstract

본 고안은 풀을 자르거나 나무를 자를 때 사용하는 휴대용 기계톱에 관한 것으로, 더욱 상세하게는 절단을 위한 기계톱날을 안전하고 확실하게 고정하는 방법에 관한 것이다.The present invention relates to a portable chainsaw used for cutting grass or cutting wood, and more particularly, to a method for safely and securely fixing a saw blade for cutting.

이를 위하여 본 고안은 기계톱날에 회전운동을 전달하는 구동축에 삽입되면서 회전하는 것을 방지할 수 있는 회전방지용 홈을 형성한 탄성이 있는 스테인레스강판으로 된 원형의 판 두 개를 점용접으로 결합시켜 그 사이에 체인형상의 톱날을 삽입하는 구조로 고안하였다.To this end, the present invention combines two circular plates made of elastic stainless steel plates with spot welding to prevent rotation by being inserted into a drive shaft that transmits rotational movement to the saw blade. It is designed to insert the chain saw blade into the structure.

체인형상의 톱날은 탄성이 있는 스테인레스강판 두장을 겹쳐 점용접으로 접합시킨 안전 고정판에 끼워져 회전하기 때문에 강력한 마찰력으로 회전하면서 나무 등의 절단을 용이하게 하면서도, 금속이나 돌 등의 물체와 접촉하게 되면 기계톱날과 안전고정판이 마찰력 만으로 회전하기 때문에 그 사이에서 미끄러짐이 발생하여 일체형 톱날 사용할 때 일어나는 톱의 파손을 방지할 수 있어 안전한 작업이 가능하도록 고안된 것이다.The chain saw blade is rotated by the safety fixing plate which is overlapped with two sheets of elastic stainless steel sheets and bonded by spot welding. Therefore, it is easy to cut wood and rotates with strong friction force, and when it comes into contact with an object such as metal or stone, Since the saw blade and the safety fixing plate rotate only with friction force, slippage is generated between them, which prevents the saw from being broken when using the integrated saw blade, and is designed to enable safe operation.

Description

회전 기계톱날 안전 고정판{Safety multi-disc for Rotary machine saw blade}Safety multi-disc for Rotary machine saw blade

본 고안은 풀이나 나무를 자르기 위하여 사용하는 휴대용 기계톱에 있어서 작은나무의 절단이나 특히 과수원의 가지치기와 풀을 자르기 위하여 사용하는 소형 휴대용 기계톱을 안전하게 사용할 수 있도록 톱날을 고정하는 회전톱날 안전고정판에 관한 것이다.The present invention relates to a safety saw blade for fixing a saw blade to safely use a small chain saw for cutting a small tree, or in particular for pruning and cutting grass, in a portable chainsaw used to cut grass or trees. will be.

이하 첨부된 도면에 의해 설명하면 다음과 같다.When described with reference to the accompanying drawings as follows.

도 1은 기존에 일반적으로 사용중인 휴대용 기계톱의 일체형 톱날(10)을 나타낸 것이다.Figure 1 shows an integrated saw blade 10 of a portable machine saw that is commonly used in the past.

이 톱날은 작은나무나 풀 등을 자를 때 쓰는 휴대용 기계톱의 톱날로서 원형의 몸체에 일체로 톱날은 형성하여 놓았기 때문에 톱날이 고가이며 돌이나 금속 등에 톱날이 접촉할 경우에 톱날이 파손되기 쉽고 기계톱날이 고속으로 회전하기 때문에 파손될 경우 그에 따른 안전사고의 위험도 높다.This saw blade is a portable saw blade for cutting small trees and grasses. Since the saw blade is formed integrally with the circular body, the saw blade is expensive and the saw blade is easily broken when the saw blade contacts metal or metal Since the saw blade rotates at high speed, there is a high risk of safety accidents if it is broken.

본 고안은 상기와 같은 문제점을 해소하기 위해 회전운동을 전달하는 구동축에, 탄성이 있는 스테인레스강판 재질인 원형의 고정판 단품 두장을 겹쳐 점용접으로 접합하여 회전 기계톱날을 고정할 수 있는 구조를 형성한 원형의 안전고정판을 설치하는데 이때 안전고정판이 구동축의 회전운동을 확실히 전달하도록 회전방지용 홈을 안전고정판에 형성한다.In order to solve the above problems, the present invention superimposes two pieces of a circular fixed plate single piece made of a resilient stainless steel plate on a drive shaft that transmits rotational motion to form a structure capable of fixing a rotating machine saw blade by joining with spot welding. The circular safety fixing plate is installed, and the anti-rotation groove is formed in the safety fixing plate so that the safety fixing plate transmits the rotational movement of the drive shaft.

이렇게 구동축에 고정된 안전고정판에 체인형상의 기계톱날을 삽입하면 탄성이 있는 스테인레스강판 재질의 안전고정판 양면이 강력한 마찰력을 일으켜 기계톱날을 잡아주게 되고 안전고정판이 회전하면서 마찰력으로 고정되어있는 체인형상의 톱날도 같이 회전하게되어 절단작업을 하게 된다.When the chain saw blade is inserted into the safety fixing plate fixed to the drive shaft, both sides of the safety fixing plate made of elastic stainless steel material generate strong friction force to hold the saw blade. The saw blade is also rotated together to cut.

절단작업중에 돌이나 금속물에 기계톱날이 접촉하게 되면 일시적으로 안전고정판과 기계톱날사이에서 미끄러짐이 발생하여 톱날의 파손도 막을 수 있으며 따라서 안전사고도 예방할 수 있다.If the saw blade comes into contact with stone or metal during the cutting operation, it may temporarily slip between the safety fixing plate and the saw blade, preventing damage to the saw blade and thus preventing safety accidents.

고안의 구성 및 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Referring to the configuration and operation of the subject innovation in detail based on the accompanying drawings as follows.

동력원으로부터 회전력을 전달하는 구동축에 고정할 구동축삽입 홈(21)의 양측에 회전방지용 홈(22)을 형성한 회전기계톱날 안전고정판 단품(20)을 두장 겹쳐서 일정한 피치원을 형성하는 위치에 다수의 점용접(31)으로 접합시킨다.A plurality of rotary machine saw blade safety fixing plate single parts 20 having anti-rotation grooves 22 formed on both sides of a drive shaft insertion groove 21 to be fixed to a drive shaft that transmits rotational force from a power source are formed in a plurality of positions at a position to form a constant pitch source. It is joined by spot welding (31).

이때 안정고정판(20)의 재질은 탄성이 있는 스테인레스강판을 사용한다.At this time, the material of the stable fixing plate 20 uses a stainless steel plate with elasticity.

점용접(31)으로 완성된 안전고정판 조립품(30)의 두판이 겹쳐지는 부분에 체인형상의 회전톱날(50)의 삽입부(51)를 원주상으로 타입하면 삽입부(51)와 안전고정판(30)사이의 마찰력으로 인하여 구동축에 연결된 안전고정판(30)이 회전하게 되면, 회전 기계톱날(50)도 마찰력으로 안전고정판(30)과 같이 회전하게 되어 원활하게 작업을 수행할 수 있다,When the insertion part 51 of the chain saw blade 50 is circumferentially formed at the portion where the two plates of the safety fixing plate assembly 30 completed by spot welding 31 overlap, the insertion part 51 and the safety fixing plate ( When the safety fixing plate 30 connected to the drive shaft is rotated due to the friction force between the 30, the rotary machine saw blade 50 is also rotated with the safety fixing plate 30 by friction force to perform the work smoothly,

이상에서 상술한 바와같이 본 고안은, 체인형상의 회전 기계톱날을 탄성이 있는 스테인레스 강판으로 형성된 안전고정판에 삽입하여 그때의 마찰력을 이용하여 고정시켜서 사용하도록 하였기 때문에 일체형 회전 기계톱날에 비하여 원가를 낮추는 것이 가능하고, 휴대용 회전 기계톱의 날부위에 적용함으로서 작업물 절단시 돌이나 금속물에 접촉하게 되는 경우라도 톱날의 파손을 막을 수 있어 안전사고를 예방할 수 있다.As described above, the present invention is designed to insert the chain-shaped rotating machine saw blade into the safety fixing plate formed of the elastic stainless steel plate and to fix it by using the friction force at that time, thereby lowering the cost compared to the integrated rotating machine saw blade. It is possible to apply to the blade portion of the portable rotary saw, it is possible to prevent the breakage of the saw blade even if it comes in contact with stones or metal objects when cutting the workpiece can prevent the safety accident.
