종래의 너트체결용 공구는 제1도에 도시한 바와 같이, 일정길이를 갖는 수직봉(1)의 상단에 수평방향으로 핸들부(2)가 용접등의 수단에 의해 고정되어 있고, 상기 수직봉(1)의 하단에는 너트(도시안됨)를 소정위치에 체결 및 분해시킬 수 있도록 너트삽입용 다각홈(3)이 형성되어 있다.In the conventional nut fastening tool, as shown in FIG. 1, the handle portion 2 is fixed to the upper end of the vertical rod 1 having a predetermined length in a horizontal direction by means of welding or the like. At the lower end of (1), a polygonal groove 3 for nut insertion is formed so that the nut (not shown) can be fastened and disassembled at a predetermined position.
그러나, 이와 같이 구성된 종래의 너트체결용 공구는, 핸들(2)을 잡고 회전시키는 힘이 수직봉(1)의 하단으로 직접 전달되기 때문에 사람의 손이 닿지 않는 좁은 공간(예컨대, 탈수조내의 펄세이터조립공정등)내에서 소정위치에 너트를 체결시킬때 많은 힘을 전달할 수 없어 체결력이 기준치에 미달되는 등의 조립불량현상이 대량 발생됨과 동시에 작업능률을 저하시킨다는 문제점이 있었다.However, in the conventional nut fastening tool configured as described above, since the force for holding and rotating the handle 2 is transmitted directly to the lower end of the vertical rod 1, a narrow space (for example, a pulsar in a dehydration tank) which is out of reach of humans. When assembling the nut at a predetermined position in the data assembly process, etc.), there is a problem in that a large amount of assembly failures such as a fastening force that is less than the standard value is generated and the work efficiency is lowered at the same time.
따라서, 본 고안은 상기 문제점을 해결하기 위하여 이루어진 것으로, 본 고안의 목적은, 공구에 감속수단을 장착하여 적은 힘에 의해 너트를 견고히 체결조립되도록 하여서 너트의 조립불량현상을 방지함과 동시에 작업능률을 향상시킬 수 있는 너트체결용 공구를 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, and the object of the present invention is to install the deceleration means on the tool to fasten and assemble the nut firmly with a small force to prevent the assembly of the nut and at the same time work efficiency To provide a nut tightening tool that can improve the.
상기 목적을 달성하기 위하여 본 고안의 너트체결용 공구는, 너트체결용 공구에 있어서, 핸들과, 상기 핸들의 회전력을 전달받아 감속시키는 감속수단과, 상기 감속수단에 교체가능케 연결되어 너트를 체결 및 분해시키는 스패너부로 이루어진 것을 특징으로 한다.In order to achieve the above object, the nut fastening tool of the present invention comprises a nut fastening tool comprising: a handle, a deceleration means for receiving and reducing the rotational force of the handle, and a replaceable connection to the deceleration means for fastening a nut and It is characterized by consisting of a spanner portion to decompose.

즉, 상기 핸들(10)은 상기 감속수단(20)의 후술하는 구동축과 체결조립 또는 용접에 의해 연결조립되어 진다.That is, the handle 10 is connected and assembled by fastening assembly or welding with the drive shaft of the deceleration means 20 to be described later.
한편, 상기 감속수단(20)은 상기 핸들(10)의 회전력을 전달받아 연동되는 구동축(21)과, 상기 구동축(21)이 삽입되어 회전자유롭게 외관을 형성하는 상부커넥터(22)와, 상기 상부커넥터(22)의 하부에 장착되어 외관을 형성하는 하부커넥터(23)와, 상기 하부커넥터(23)의 외부 일측에 수평으로 고정결합된 보조손잡이부(24)와, 상기 하부커넥터(23)에 동축적으로 삽입되어 회전자유롭게 장착됨과 동시에 상기 구동축(21)의 하단과 감속부(25)를 매개로 연결되어 상기 스패너부(40)를 감속회전시키는 종동축(26)으로 이루어져 있다.On the other hand, the deceleration means 20 is the drive shaft 21 and the drive shaft 21 is interlocked by receiving the rotational force of the handle 10, the drive shaft 21 is inserted into the upper connector 22 to freely rotate the appearance and the upper A lower connector 23 mounted on a lower portion of the connector 22 to form an exterior, an auxiliary handle 24 fixed to the outer side of the lower connector 23 horizontally, and a lower connector 23. The shaft is inserted coaxially and freely mounted, and is connected to the lower end of the drive shaft 21 and the reduction unit 25 via a driven shaft 26 to decelerate and rotate the spanner part 40.
이때, 상기 감속부(25)는 상기 구동축(21)의 하단에 맞물려 회전되는 선기어(27)와, 상기 선기어(27)의 외측에 맞물진 다수개의 유성기어(28)와, 상기 유성기어(28)가 다수개의 축(29)을 매개로 감속회전되게 지지함과 동시에 상기 구동축(21)과 결합된 상부캐리어(30)와, 상기 유성기어(28)가 상기 축(29)을 매개로 감속회전되게 지지함과 동시에 상기 종동축(26)의 상단과 세레이션방식으로 결합된 하부캐리어(31)로 이루어져 있다.In this case, the reduction unit 25 is a sun gear 27 is rotated in engagement with the lower end of the drive shaft 21, a plurality of planetary gears 28 meshed to the outside of the sun gear 27, and the planetary gear 28 ) Is supported by the plurality of shafts 29 to be decelerated and rotated at the same time, the upper carrier 30 coupled with the drive shaft 21, and the planetary gears 28 are decelerated through the shaft 29 At the same time, the upper carrier of the driven shaft 26 and the lower carrier 31 is coupled in a serration manner.
또, 상기 다수개의 유성기어(28)는 그 외측이 상기 상부커넥터(22)의 내측에 형성된 내접기어부(32)와 맞물려 회전하게 된다.In addition, the plurality of planetary gears 28 is rotated by engaging the internal gear portion 32 formed on the inner side of the upper connector 22 on the outside thereof.
그리고, 상기 상부커넥터(22)와 구동축(21) 및 하부커넥터(23)와 종동축(26) 사이에는 구동축(21)과 종동축(26)의 회전을 원활히하도록 부싱(33)이 장착되어 있다.In addition, a bushing 33 is mounted between the upper connector 22 and the drive shaft 21 and the lower connector 23 and the driven shaft 26 so as to smoothly rotate the drive shaft 21 and the driven shaft 26. .
한편, 상기 스패너부(40)는 그 하부에 형성된 다각홈(41)의 여러종류에 따라 교환사용이 가능토록 상기 종동축(26)과 착탈되어 진다.On the other hand, the spanner portion 40 is attached to and detached from the driven shaft 26 to be interchangeable depending on the type of the polygonal groove 41 formed in the lower portion.
도면 중 미설명 부호 50은 탈수조, 51은 펄세이터, 52는 너트, 53은 동력전달수단, 54는 동력전달수단(53)의 회전축이다.In the drawings, reference numeral 50 denotes a dehydration tank, 51 a pulsator, 52 a nut, 53 a power transmission means, and 54 a rotation shaft of the power transmission means 53.
다음에는, 이와 같이 구성된 본 고안의 작용 및 효과를 설명한다.Next, the operation and effects of the present invention configured as described above will be described.
제3도와 같이 탈수조(50)내의 바닥으로 돌출된 동력전달수단(53)의 회전축(54)에 펄세이터(51)를 너트(52)를 매개로 체결조립하기 위하여 상기 너트(52)를 공구의 스패너부(40)에 형성된 다각홈(41)에 끼우고 핸들(10)을 회전시켜 구동축(21)을 회전시켜 주면, 이 구동축(21)은 그 하단에 장착된 선기어(27)를 동시 회전시켜줌과 동시에 이에 맞물려진 다수개의 유성기어(28)를 회전시켜 하부캐리어(31)를 회전시켜 주게 되고, 이 하부캐리어(31)는 상기유성기어(28)의 회전에 의한 감속작동에 의해 회전수가 감속되면서 적은 힘에 의해 큰 힘을 갖는 작용을 함에 따라 그 중앙에 세레이션방식으로 장착된 종동축(26)을 회전시켜 줌과 동시에 종동축(26)과 동시 회전되도록 그 하단에 착탈가능케 장착된 스패너부(40)를 회전시켜 주게 됨으로써 너트(52)는 동력전달수단(53)의 회전축(54)에서 용이하게 체결 또는 분해가 되어 진다.The nut 52 is tooled to fasten and assemble the pulsator 51 via the nut 52 to the rotary shaft 54 of the power transmission means 53 protruding to the bottom in the dewatering tank 50 as shown in FIG. 3. When the drive shaft 21 is rotated by inserting it into the polygonal groove 41 formed in the spanner portion 40 and rotating the handle 10, the drive shaft 21 simultaneously rotates the sun gear 27 mounted at the lower end thereof. At the same time, the lower carrier 31 is rotated by rotating the planetary gears 28 engaged with the planetary gears, and the lower carrier 31 is rotated by a deceleration operation by the rotation of the planetary gear 28. As it acts as a deceleration and has a large force by a small force, it rotates the driven shaft 26 mounted in a serration manner in the center thereof, and is detachably mounted at the bottom thereof so as to rotate simultaneously with the driven shaft 26. Rotating the spanner portion 40, the nut 52 is the power transmission means 53 Easily from the front barrel 54 to be fastened or is a degradation.
이때, 상기 공구는 조립작업위치가 불안전한 장소에서도 적은 힘에 의해 큰 힘으로 너트(52)를 견고히 체결조립할 수 있으므로 너트(52)의 체결력이 기준치에 미달되는 등의 조립불량현상을 미연에 방지할 수 있음과 동시에 작업능률을 향상시킬 수 있는 것이다.At this time, since the tool can be firmly fastened to the nut 52 with a large force even in a place where the assembly operation position is unstable, it is possible to prevent the assembly failure such that the fastening force of the nut 52 is less than the standard value. At the same time, work efficiency can be improved.
이상에서 설명한 바와 같이 본 고안의 너트체결용 공구는, 감속수단의 감속작용에 의해 핸들의 적은 힘이 스패너부에서는 큰 힘으로 회전동작되어 너트를 협소한 공간에서도 쉽고 견고히 체결조립할 수 있는 구조로 되어 있기 때문에 너트의 조립불량현상을 방지함과 동시에 작업능률을 향상시킬 수 있는 효과가 있다.As described above, the nut fastening tool of the present invention has a structure in which a small force of the handle is rotated by a large force in the spanner part by a deceleration action of the deceleration means so that the nut can be easily and firmly assembled in a narrow space. Therefore, it is possible to prevent the assembly of nuts and improve the work efficiency.
