본 고안은 후방 배기형 공기공구에 관한 것이다.The present invention relates to a rear exhaust air tool.

공기공구를 사용한 연삭작업이나 연마작업에 있어서의 연삭된 가루의 집진방식은, 개별집진과 집중집진으로 대별할 수 있으나, 집진로는 송기로의 분기관에 접속되어 있어서, 이 접속부에서 생기는 부압력(負壓力)으로 연삭부 근처의 부유 연삭분을 흡인하도록 한 구조로 되어 있다. 그래서, 송기로와 집진로를 모두 내장한 손잡이부를 보면, 이 송기로와 집진로는 제6도와 제7도에 표시한 바와 같이, 접속수단에 의해 송기관과 집진관이 접속되어 있어서 집진부가 소경집진관 접속방식을 채택하고 있으므로 제6도에 표시한 바와 같이 소경집진관(36)을 손잡이부(31)의 집진로(33)에 접속할 필요가 있고, 대경집진관 접속방식을 채택하고 있으면, 제7도에 표시한 바와 같이 대경 집집관을 손잡이부(1)에 접속할 필요가 있다. 또한 도면 중 32는 송기로, 37은 호오스연결구, 38은 송기호오스이다.The dust collecting method of the ground powder in the grinding work or the polishing work using the air tool can be roughly divided into the individual dust collection and the concentrated dust collection. However, the dust collection path is connected to the branch pipe to the air blower, so that the negative pressure generated at this connection part It has a structure which sucks the floating grinding powder in the vicinity of a grinding part by virtue of it. Therefore, when looking at the handle part incorporating both the air flow path and the dust collecting path, as shown in FIG. 6 and FIG. 7, the air supply pipe and the dust collecting pipe are connected by the connecting means, and the dust collecting part has a small diameter. Since the dust collecting pipe connection method is adopted, as shown in FIG. 6, when the small diameter dust collecting pipe 36 needs to be connected to the dust collecting path 33 of the handle part 31, and the large diameter collecting pipe connecting method is adopted, As shown in FIG. 7, it is necessary to connect the large diameter collector tube to the handle part 1. As shown in FIG. In the figure, 32 is an air supply, 37 is a hose connector, and 38 is an air supply hose.

그래서 이러한 연삭 공기공구의 사용자측에서 보면 집진부가 한정되게 되므로, 예를 들면 소경집진관 접속방식의 집진부를 구비하고 있는 사용자에 대해서는 제7도에 표시한 바와 같은 손잡이부를 가진 공기공구는 부적당한 것이 되고, 결국, 제조자, 판매자측은 손잡이부의 구조가 다른 2기종을 준비해 두지 않으면 안된다는 것이 그 실정이였다.Therefore, since the dust collecting part is limited when viewed from the user side of the grinding air tool, for example, an air tool having a handle part as shown in FIG. 7 becomes inadequate for a user equipped with a dust collecting part of a small diameter dust collecting pipe connection method. In the end, the manufacturer and the seller had to prepare two models with different handle parts.

본 고안은 집진방식이나 접속방식이 다르다는 이유로 2기종을 준비해야 한다는 비 경제적인 면을 해소시키는 것을 목적으로 하는 것으로서, 어댑터를 부착, 또는 제거하는 것 만으로, 두가지 집진부 접속방식에 공용할 수 있도록 한 것을 특징으로 하는 것이다.The present invention aims at eliminating the uneconomical aspect of having to prepare two models due to different dust collection methods and connection methods, and it is possible to share the two dust collector connection methods simply by attaching or removing an adapter. It is characterized by.

다음에 본 고안의 실시예를 도면에 의하여 설명하면, 1은 압축공기를 구동원(源)으로 하는 그라인더, 연삭기등으로 된 공기공구(도시하지 않음)의 본체에 연결한 손잡이부로서, 이 손잡이부에, 공기 공급원(도시하지 않음)에 접속하는 접속부, 예를 들면 호오스 연결구를 연결하는 나사구멍(4)을 단부 내면에 설치한 송기로(2)와, 공기공구의 본체측의 손잡이부 끝에 설치한 흡기개구(도시하지 않음)에 연통하게 한 흡기로(3)를 각각 설치하여, 이 손잡이부(1)의 후단 외주에는 접속부(1a)를 형성시켰다.Next, an embodiment of the present invention will be described with reference to the drawings, where 1 is a handle portion connected to a main body of an air tool (not shown) made of a grinder, a grinding machine, etc., which uses compressed air as a driving source. To the air supply unit (2) provided at the inner side of the end with a screw hole (4) connecting a connecting portion for connecting an air supply source (not shown), for example, a hose connector, to the end of the handle of the main body side of the air tool. The intake paths 3 which communicated with each intake opening (not shown) were provided, respectively, and the connection part 1a was formed in the outer periphery of the rear end of this handle part 1. As shown in FIG.

5는 손잡이부(1)의 단부(端部)에 패킹(15)을 끼워서 볼트(6)(6)로서 붙이고 떼기를 자유롭게 부착한 어댑터로서, 이 어댑터(5)에는, 상기한 공기 공급원으로 접속하는 접속부, 예컨데 나사부(7)를 구비하고, 또한 상기한 송기로(2)와 합치하는 송기구(16)과, 소경집진관(11)을 연결하기 위한 접속통부(8)를 구비하며 또한 상기한 흡기로(3)와 합치하는 흡기공(17)을 갖고 있다.5 is an adapter in which the packing 15 is attached to the end of the handle 1 and attached as bolts 6 and 6, and the detachment is freely attached. The adapter 5 is connected to the air supply source described above. A connecting part (8) having a connecting portion (e.g., a screw portion 7), and an air supply mechanism (16) matching the above-described air passage (2), and a connecting cylinder (8) for connecting the small diameter dust collecting pipe (11). It has an intake hole 17 which coincides with one intake path 3.

9는 나사구멍(4) 또는 나사부(7)에 붙이고 떼기를 자유로 나사맞춤하는 호오스 연결구, 10은 송기호오소, 11은 소경집진관, 12는 대경호오스이다.9 is a hose connector which is attached to the screw hole 4 or the threaded portion 7, and is freely screwed off, 10 is a sending air hose, 11 is a small diameter dust collecting tube, and 12 is a large diameter hose.

도면 중에, 19는 보울트 구멍이다.In the figure, 19 is the bolt hole.

다음에 작용에 대하여 설명한다.Next, the operation will be described.

먼저, 집중집진장치(도시하지 않음)를 갖지 않는 공장에서 이 공구를 사용할 경우에는, 제1도, 제5도에 표시한 바와 같이, 어댑터(5)를 패킹 (15)을 끼워서 볼트(6)(6)로서 손잡이부(1)의 끝부분에 고착하고, 그 다음에 접속통부(8)에는 휴대용의 소경집진관(11)을 끼워서 부압발생장치(도시하지 않음)를 장착하고, 다시 후단을 압축기(도시하지 않음)에 접속시킨 송기호오스(10)의 선단에 부착한 호오스연결부(9)를 어댑터(5)의 나사부(7)에 죄여 붙인다.First, when using this tool in a factory that does not have a concentrated dust collector (not shown), as shown in FIG. 1 and FIG. 5, the adapter 5 is fitted with the packing 15, and the bolt 6 (6), to the end of the handle portion 1, and then, the connection cylinder 8 is fitted with a portable small diameter dust collecting tube 11 to attach a negative pressure generating device (not shown), and then the rear end is The hose connecting portion 9 attached to the tip of the air sending hose 10 connected to the compressor (not shown) is tightened to the screw portion 7 of the adapter 5.

이 상태에서 압축공기를 공기공구에 공급하여, 그라인더 등을 구동시켜서 연삭작업을 한다. 그리하여, 피연삭분을 함유한 배기는, 부압발생장치에 의한 부압에 의하여 흡기공(도시하지 않음)으로부터 손잡이부내를 통하고, 또한 어댑터(5)의 접속통부(8)를 거쳐서 소경집진관(11)내에 진입하여, 먼지를 집진한 후의 공기는 대기중에 배출된다. 이 경우, 공기공구는 압축기에 접속된 송기호오스(10)가 미치는 범위내에서 자유로히 이동하여 작업을 할 수가 있다.In this state, compressed air is supplied to an air tool, and the grinder or the like is driven to perform grinding work. Thus, the exhaust gas containing the grinding powder passes through the handle portion from the intake hole (not shown) by the negative pressure generated by the negative pressure generating device and through the connecting cylinder 8 of the adapter 5. 11) After entering and collecting dust, air is discharged to the atmosphere. In this case, the air tool can move freely and work within the range of the air supply hose 10 connected to the compressor.

다음에, 집중집진장치를 가진 공장등에서 사용할 경우에는, 이 어댑터(5)는 불필요하게 되므로, 보울트(6)(6)를 풀어서 어댑터(5)를 손잡이부(1)의 단부에서 빼내어서, 송기호오스(10)의 선단에 부착한 호오스연결구(9)를 송기로(2)의 나사구멍(4)에 나사맞춤함과 동시에, 이 손잡이부(1)와 집중집진장치(도시하지 않음)에 연결된 대경 집진관을 대경호오스(12)로서 연결한다(제7도). 이 때문에 공기공구로서 연삭작업을 할 경우, 이 공구는 송기호오스(10)의 길이와 집진용의 대경호오스(12)의 길이의 범위내에서만 이동되므로, 작업성이 떨어진다. 또한 어댑터(5)는 패킹(15)를 끼워서 손잡이부(1)의 단부에 부착되어 있으므로, 송기로와 송기공, 및 흡기로와 흡기공과의 사이의 누설을 방지함과 동시에, 손잡이부와 어댑터와의 사이의 진동의 전달을 얼마만큼 흡수할 수가 있다.Next, when using in a factory having a concentrated dust collector or the like, this adapter 5 becomes unnecessary, so that the bolts 6 and 6 are loosened, and the adapter 5 is pulled out from the end of the handle portion 1, so that the The hose connector 9 attached to the tip of the oscillator 10 is screwed into the screw hole 4 of the air passage 2 and connected to the handle 1 and the dust collector (not shown). The large diameter dust collector is connected as the large diameter hose 12 (FIG. 7). For this reason, when the grinding work is carried out as an air tool, the tool is moved only within the range of the length of the air delivery hose 10 and the length of the large diameter hose 12 for dust collection, resulting in poor workability. In addition, since the adapter 5 is attached to the end of the handle portion 1 with the packing 15 inserted therein, the handle portion and the adapter are prevented while at the same time preventing leakage between the air passage and the air inlet, and the intake passage and the intake hole. It can absorb how much vibration transfers between and.

이상과 같이, 본 고안은, 공기공구의 손잡이부에 공기 공급원으로 접속하는 접속부를 구비한 송기로와, 공기공구의 흡기 개구에 통하는 흡기로를 설치하고, 또한 이 송기로 및 흡기로의 개구단부에는, 공기 공급원으로 접속하는 접속부를 구비한 송기공과 소경집진관의 접속통부를 구비한 흡기공을 가지며, 또한 상기한 송흡기공이 상기 송기로와 흡기로에 각기 연통 가능한 어댑터를 붙이고 떼기를 자유롭게 설치하고, 또 다시 상기 손잡이부 단부에는, 전자보다 대경의 집진관을 접속하기 위한 접속부를 형성한 구성이므로, 필요에 따라 이 어태치먼트를 붙이고 떼기만 하면 되고, 손잡이부가 소형이므로 사용하는 재료가 적어도 되어 코스트다운을 도모할 수 있는 동시에, 경량화도 도모할 수 있는 결과 조작성도 좋아지고, 개별식 또는 집중식 집진방식의 어느 타입으로도 사용할 수 있는 범용성을 갖고 있는 것이다.As described above, the present invention provides an air inlet having a connecting portion for connecting to the handle of the air tool as an air supply source, and an intake air passage through the intake opening of the air tool. Has an air intake hole having a connection portion connected to an air supply source and an air intake hole having a connection tube portion of a small diameter dust collecting tube, and the air intake hole has an adapter which can communicate with each of the air intake passage and the intake passage, and is freely installed In addition, since the connection part for connecting a larger diameter dust collecting tube than the former was formed in the said handle part edge part, it is only necessary to attach and remove this attachment as needed, and since the handle part is small, the material to be used is at least cost As well as down, weight reduction can be achieved, and the operability is improved, and individual or central dust collection room It has a general purpose that can be used with any type of expression.
