본 고안은 간편히 휴대하면서 사용할수 있고 구조가 매우 간단한 휴대용 전동태핑(Tapping)공구에 관한 것이다.The present invention relates to a portable electric tapping tool that is simple to carry and can be used.
종래에 사용되어온 일반적인 태핑머신은 드릴링머신과 거의 유사한 구조로 되어있다.The conventional tapping machine used in the prior art has a structure almost similar to that of a drilling machine.
즉, 종래의 태핑머신은 제3도와 같이 받침판(21)과 지지대(22), 지지대 상단에 고정된 구동박스(23), 구동박스 일측에 고정된 모터(24), 모터축에 고정된 구동풀리(25), 구동풀리와 벨트(27)에 의해 연결된 종동풀리(26), 종동풀리에 고정된 고정스핀들(28)과 이송스핀들(29), 이송스핀들의 하단부에 고정된 척(30)과 탭(31), 스위치(32)를 포함한 제어유니트(33)등으로 구성되어 있다.That is, the conventional tapping machine is a support plate 21 and the support 22, the drive box 23 fixed to the top of the support, the motor 24 fixed to one side of the drive box, the drive pulley fixed to the motor shaft as shown in FIG. (25), driven pulley (26) connected by drive pulley and belt (27), fixed spindles (28) and transfer spindles (29) fixed to the driven pulley, chuck (30) and tabs fixed to the lower ends of the transfer spindles And a control unit 33 including a switch 32.
따라서 스위치(32)를 온시키면 모터(24)가 회전함과 동시에 그 구동력이 풀리(25)(26)와 벨트(27)를 통해 고정스핀들(28)에 전달되어 고정스핀들(28)이 회전하게 되고 고정스핀들(28)이 회전하면 이송스핀들(29)이 고정스핀들과 같은 방향으로 회전하면서 하강하게 되므로 척(30)에 물린 탭(31)에 의하여 공작물의 태핑작업이 이루어진다.Accordingly, when the switch 32 is turned on, the motor 24 rotates and the driving force is transmitted to the fixed spindles 28 through the pulleys 25 and 26 and the belt 27 so that the fixed spindles 28 rotate. When the fixed spindles 28 rotate, the feed spindles 29 are lowered while rotating in the same direction as the fixed spindles, so that tapping of the workpiece is performed by the tab 31 bited by the chuck 30.
또 이송스핀들(29)이 제어유니트(33)에 미리 설정된 행정거리 만큼 하강하여 태핑작업이 완료되면 제어유니트에 의해 모터(24)가 자동적으로 역회전하게 되고 그 회전력이 고정스핀들(28)에 전달되어 이송스핀들(29)과 척(30)및 탭(31)은 태핑작업시의 반대방향으로 회전하면서 상승하게 된다.In addition, when the feeding spindle 29 is lowered by a predetermined stroke distance to the control unit 33 and the tapping operation is completed, the motor 24 is automatically reversed by the control unit, and the rotational force is transmitted to the fixed spindle 28. The feed spindle 29 and the chuck 30 and the tab 31 are raised while rotating in the opposite direction during the tapping operation.
그러나 상기한 바와 같은 종래의 태핑머신은 탁상형으로 고정시킨 상태에서 공작물을 가공하도록 되어 있기때문에 휴대가 불가능하고 받침판(21)과 탭(31)사이의 거리가 한정되어 일정크기 이상의 공작물은 가공할수 없는 불편함이 있다.However, the conventional tapping machine as described above is not portable because it is designed to process the workpiece in the fixed state of the table type, and the distance between the support plate 21 and the tab 31 is limited so that a workpiece of a certain size or more can be processed. There is no inconvenience.
또한 모터의 구동력이 풀리와 벨트에 의해 탭에 전달되는 구조 이어서 기계의 외형이 커지고 가격이 비싸지는 문제도 있다.In addition, since the driving force of the motor is transmitted to the tab by the pulley and the belt, there is also a problem that the appearance of the machine is large and expensive.
본 고안은 벨트와 풀리에 의해 동력을 전달하는 종래의 태핑 머신과는 달리 원추형의 고무로울러와 역시 원추형의 마찰차에 의해 모터의 동력을 스핀들에 정, 역방향으로 전달시킬수 있고 외형이 축소되어 휴대가 가능해질수 있는 전동태핑공구를 제공하기 위한 것인바, 이를 첨부된 도면 제1도에 의해 더욱 상세히 설명하면 다음과 같다.Unlike the conventional tapping machine that transmits power by belt and pulley, the present invention can transfer power of motor to spindle by forward and reverse direction by conical rubber roller and conical friction difference. It is to provide an electric tapping tool that can be enabled, described in more detail by the accompanying drawings, Figure 1 as follows.
손잡이부(1a)가 일체로 형성된 하우징(1)의 내부에 모터(2)를 설치하여 모터축(3)에 원추형 고무로울러(4)를 고정하고 그 일측에는 정회전 원추마찰차(6)와 역회전 원추마찰차(7)가 고정된 스핀들(5)을 설치하여 원추형 고무로울러(4)와 각 원추마찰차(6)(7)사이에 위치되도록 함과 함께 스핀들(5)의 하단에 척(8)과 탭(9)을 고정하여 원추형 고무로울러가 각 원추마찰차에 선택적으로 접속함에 따라 스핀들이 정, 역방향으로 회전될수 있게 한것이다.The motor 2 is installed inside the housing 1 in which the handle portion 1a is integrally fixed to fix the conical rubber roller 4 to the motor shaft 3, and at one side thereof, a forward-rotating conical friction car 6 and The reverse rotation cone friction car 7 is installed with a fixed spindle 5 so as to be located between the conical rubber roller 4 and each cone friction car 6 and 7 and the chuck at the bottom of the spindle 5. (8) and tab (9) are fixed so that the spindle can be rotated forward and backward as the conical rubber roller is selectively connected to each conical friction car.
도면중 미설명 부호 10은 모터축을 지지하는 베어링, 11은 모터축에 고정된 냉각팬, 12는 스핀들을 지지하는 베어링, 13은 원추마찰차를 스핀들에 고정하기 위한 플랜지, 14는 전원스위치이다.In the drawings, reference numeral 10 denotes a bearing for supporting the motor shaft, 11 a cooling fan fixed to the motor shaft, 12 a bearing for supporting the spindle, 13 a flange for fixing the conical friction car to the spindle, and 14 a power switch.
이와 같이 구성된 본 고안의 전동태핑공구를 이용한 공작물의 태핑작동을 설명한다.It describes the tapping operation of the workpiece using the electric tapping tool of the present invention configured as described above.
먼저 스위치(14)를 모터(2)에 전원이 인가되어 모터축(3)과 냉각팬(11)및 원추형 고무로울러(4)가 회전을 하게 된다.First, power is applied to the motor 2 of the switch 14 so that the motor shaft 3, the cooling fan 11, and the conical rubber roller 4 rotate.
이러한 상태에서 손잡이부(1a)를 손으로 잡고 탭(9)을 공작물에 접속시킨후 하방으로 힘을 가해주면 탭(9)과 척(8)및 스핀들(5)이 상승하여 제1도와 같이 스핀들(5)에 고정된 정희전 원추마찰차(6)가 원추형 고무로울러(4)와 접속하게 되고 이에따라 모터축(3)의 구동력이 원추형 고무로울러(4)와 정회전 원추마찰차(6)를 통해 스핀들(5)에 정방향으로 전달되므로 척(8)과 탭(9)이 정방향으로 회전하여 공작물에 나사가공이 이루어진다.In this state, hold the handle 1a by hand, connect the tab 9 to the workpiece, and apply downward force. The tab 9, the chuck 8, and the spindle 5 are raised to form the spindle as shown in FIG. The jeonghuijeon conical friction car 6 fixed at (5) is connected to the conical rubber roller 4, and accordingly, the driving force of the motor shaft 3 is connected to the conical rubber roller 4 and the forward rotation conical friction car 6. Since it is transmitted to the spindle 5 in the forward direction, the chuck 8 and the tab 9 are rotated in the forward direction so that the workpiece is threaded.
또 태핑작업이 끝난후 공구를 상방으로 들어올리면 탭(9)이 공작물에 물려있기 때문에 공구가 들어올려 짐에 따라 제2도와 같이 원추형 고물로울러(4)가 스핀들(5)에 고정된 역회전 원추마찰차(7)에 접속하게되고 모터축(3)의 구동력이 역회전 원추마찰차(7)를 통해 스핀들(5)에 역방향으로 전달되므로 척(8)과 탭(9)이 역방향의 회전을 하면서 상승하여 공작물로부터 분리된다.In addition, if the tool is lifted upward after the tapping operation is finished, since the tab 9 is stuck to the workpiece, the reverse cone is fixed to the spindle 5 with the conical solid roller 4 as shown in FIG. 2 as the tool is lifted. It is connected to the friction wheel (7) and the driving force of the motor shaft (3) is transmitted to the spindle (5) in the reverse direction through the reverse rotational friction friction wheel (7), so that the chuck (8) and the tab (9) reverse rotation Ascends and separates from the workpiece.
이상에서와 같이 본 고안은 모터축에 고정된 원추형 고무로울러가 스핀들에 고정된 2개의 원추마찰차중 어느하나의 원추마찰차에 접속함에 따라 스핀들이 정, 역방향의 회전을 하게되어 있으므로 동력전달을 위한 풀리와 벨트등의 부품이 불필요하게 되고 이에따라 공구의 소형화가 가능하여 휴대용으로 사용할수 있게된다.As described above, according to the present invention, when the conical rubber roller fixed to the motor shaft is connected to one of the two conical friction cars fixed to the spindle, the spindle rotates in the forward and reverse directions so that power transmission is performed. Parts such as pulleys and belts are no longer needed, and accordingly, the tool can be miniaturized and can be used in a portable manner.
또 공구의 휴대가 용이해짐에 따라 공작물의 크기나 장소에 제한받지 않고 어느곳에서나 태핑작업을 할수 있게되며, 저렴한 가격에 공급할수 있게되는 효과가 있다.In addition, as the tool is easy to carry, the tapping operation can be performed anywhere without being limited to the size or location of the workpiece, and it is possible to supply at a low price.
