본 고안은 자동차의 뒷바퀴에 조립되는 부품인 캐리어(carrier)의 선삭용 지그에 관한 것으로, 상세하게는 선반척에 고정되는 지그본체에 고정판을 고정시키되 그 사이에 캐리어를 고정 설치하여 캐리어의 내경 테이퍼홀과 외경을 동시에 가공할 수 있도록 캐리어를 선반척에 용이하게 고정할 수 있도록한 캐리어 가공 선삭용 지그에 관한 것이다.The present invention relates to a turning jig for a carrier (carrier), which is a component assembled on the rear wheel of a vehicle, and in detail, a fixing plate is fixed to a jig body fixed to a lathe chuck, and a carrier is fixed therebetween to taper the inner diameter of the carrier. The present invention relates to a jig for carrier machining turning which allows a carrier to be easily fixed to a lathe chuck so as to simultaneously process a hole and an outer diameter.

일반적으로 캐리어는 동력이 전달되는 바퀴와 현가장치 사이에 들어가는 부품으로 내측에는 스핀들을 조립할 수 있는 베어링이 들어가고, 외측은 브레이크 드럼과 조리되는 부품으로 선반에서 내, 외측이 모두 정밀하게 가공되어야 한다.In general, the carrier is a part that enters between the wheel and the suspension to which power is transmitted, and a bearing for assembling the spindle is included in the inside, and the outside is a brake drum and a cooked part.

그러나, 종래의 캐리어 가공 선삭용 지그는 첨부도면 제1도에 도시되는 바와 같이 밀링에서 캐리어(1)의 일측부(1a)를 작업하되, 이때 4곳의 홀(1b)을 포함하여 동시에 가공하고, 지그(2)를 이용하여 캐리어(1)의 타측부(1c)를 선반척(3)쪽을 향하게 하여 셋팅한후, 캐리어(1)의 내경 테이퍼홀(1d)을 가공하였다.However, the conventional jig for turning a carrier is to work one side (1a) of the carrier (1) in milling, as shown in Figure 1 of the accompanying drawings, and at the same time including four holes (1b) After setting the other side 1c of the carrier 1 toward the lathe chuck 3 using the jig 2, the inner diameter taper hole 1d of the carrier 1 was processed.

여기서 캐리어(1)는 4곳의 홀(1b)을 이용하여 지그(2)에 셋팅한다.Here, the carrier 1 is set to the jig 2 using four holes 1b.

따라서, 이러한 종래의 기술은 캐리어(1)의 내,외경을 각각 별도의 절삭기계에서 작업하여 가공하였기 때문에 동심도 일치하지 않아 불량 및 셋팅시간이 과다하게 소요되는 문제점이 있었다.Therefore, this conventional technique has a problem in that the inner and outer diameters of the carrier 1 are processed by separate cutting machines so that the concentricity does not coincide, resulting in excessive defects and excessive setting time.

본 고안은 상기에서와 같은 종래의 결점을 해소하기 위해 안출한 것으로써 이의 목적은 하나의 절삭기계에서 한번의 고정으로 작업이 이루어져 작업이 용이할 뿐만 아니라 동심도가 일치하여 불량의 원인을 제거하고 또한, 각 기계마다 새로이 셋팅해야만하는 번거러움과 셋팅시간을 극감시키는 캐리어 가공 선삭용 지그를 제공하는데 있다.The present invention has been devised to solve the above-mentioned drawbacks as described above, and its purpose is to work with one fixing on one cutting machine, making it easy to work and eliminating the cause of defects by matching concentricity. In order to reduce the hassle and setting time for each machine, it is necessary to provide a carrier machining jig.

While the pinhole is formed and the jig main body has fixed holes and tab holes formed on the concentric circles larger than the concentric circles of the pin hole, and the frame body having a predetermined thickness has pin holes like the jig main body, and the pins are fixed on the concentric circles such as the fixing holes. It is fixed by a screw and is formed by a carrier processing jig, characterized in that the center portion is formed with a through-hole to facilitate the taper hole processing of the carrier, the bolt is installed in the same position as the tap hole.

As shown in FIG. 2, the present invention is fixed to the jig main body 10 and the jig main body 10 including a body 10b integrally formed with a fixed part 10a fixed to the lathe chuck 20. The carrier 30 is installed between the jig main body 10 and the fixed plate 40 by the pin 41 is fixed to the fixed plate 40 is fitted.

이를 구체적으로 설명하면 상기 지그본체(10)는 선반척(20)에 용이하게 고정될 수 있도록 원통형의 고정부(10a)를 구비하며, 상기 고정부(10a)의 일측으로는 이와 일체로 형성된 돌출단부(15)를 구비하면서 중심에는 지름이 크고 고정부(10a)쪽으로 갈수록 점점 작게 형성된 통공을 갖으며, 돌출단부(15)의 양측부로는 캐리어(30)를 삽입할 수 있는 고정공간(16)이 대향되게 형성되고 이 고정공간(16)을 중심선으로하여 서로 대향되게 몸체(10b)로 이루어 구성된다.Specifically, the jig body 10 includes a cylindrical fixing part 10a so that the jig main body 10 can be easily fixed to the lathe chuck 20, and one side of the fixing part 10a protrudes integrally therewith. It has an end portion 15 has a large diameter in the center and has a through hole formed gradually toward the fixing portion 10a, the fixing space 16 for inserting the carrier 30 to both sides of the protruding end portion 15 The body 10b is formed to face each other and face each other with the fixed space 16 as a centerline.

한편, 고정부(10a)와 일체로된 몸체(10b)에는 핀홀(11)을 등간격으로 다수 형성하면서 핀홀(11)의 동심원상보다 큰 동심원상에는 고정홀(12)이 다수 구비하고 상기 고정홀(12)의 동심원상에 고정공간(16)과 직교되는 선상에 탭홀(13)을 형성한다.Meanwhile, a plurality of pinholes 11 are formed in the body 10b integrated with the fixing portion 10a at equal intervals, and a plurality of fixing holes 12 are provided on the concentric circles larger than the concentric circles of the pinholes 11 and the fixing holes. A tap hole 13 is formed on a line orthogonal to the fixed space 16 on the concentric circle of (12).

상기 고정판(40)은 지그본체(10)의 핀홀(11)과 같은 위치에 같은 수의 핀홀(44)과 고정홀(12)에 삽입되는 고정핀(41)이 설치되어 핀고정나사(42)에 의하여 고정되어 있으며, 상기 틀체(40a)의 중앙부에는 캐리어(30)의 테이퍼공 가공이 용이하도록 관통공(45)이 형성되어 있다. 미설명부호 31은 캐리어 본체이며 32는 이 캐리어 본체에 구비된 핀홀이다.The fixing plate 40 is provided with the same number of pinholes 44 and fixing pins 41 inserted into the fixing holes 12 at the same position as the pinholes 11 of the jig body 10. It is fixed by, the through hole 45 is formed in the center of the frame (40a) to facilitate the taper hole processing of the carrier (30). Reference numeral 31 is a carrier body and 32 is a pinhole provided in the carrier body.

이와같은 구조로 이루어진 본 고안인 캐리어 가공 선삭용 지그의 작용 효과를 설명하면 고정부(10a)를 선박척(20)에 척킹하여 지그본체(10)를 고정 설치한 다음 캐리어(30)를 지그본체(10)의 고정공간(16)에 삽입한다.When explaining the effect of the carrier jig for machining the present invention having such a structure described above chucking the fixed portion (10a) to the ship chuck 20, the jig main body 10 is fixedly installed and then the carrier 30 is jig main body It is inserted into the fixed space 16 of (10).

이때, 캐리어(30)에 천공된 핀홀(31)과 지그본체(10)에 천공된 핀홀(11) 및 고정판(40)의 핀홀(44)을 일치시킨 후 핀을 삽입하여 각각의 캐리어(30), 지그본체(10) 및 고정판(40)이 유동되지 않도록하고 그리고, 상기 고정판(40)에 설치된 고정핀(41)을 지그본체(10)에 구비된 고정홀(12)과 일치시킨 다음 핀고정나사(42)를 풀어 고정핀(41)을 고정홀에 삽입되도록하여 고정판(40)과 지그본체(10)의 간격을 맞춘다음 핀고정나사(42)를 조여 유동되지 않도록하며, 지그본체(10)에 형성된 탭홀(13)에 볼트(43)를 체결하여 고정시켜 선반척(20)이 작동되어 회전하더라도 유동되지 않도록 한다. 상기와 같이 셋팅이 완료되면 틀체(45)의 관통공을 통하여 내측 테이퍼홀을 가공하며 캐리어를 고정된 상태에서 외측면을 가공한다.At this time, the pinhole 31 perforated in the carrier 30 and the pinhole 11 perforated in the jig body 10 and the pinhole 44 of the fixing plate 40 are matched, and then a pin is inserted into each carrier 30. To prevent the jig body 10 and the fixing plate 40 from flowing, and matching the fixing pin 41 installed on the fixing plate 40 with the fixing hole 12 provided in the jig body 10, pin fixing is performed. Loosen the screw 42 so that the fixing pin 41 is inserted into the fixing hole so that the gap between the fixing plate 40 and the jig body 10 is adjusted, and then tighten the pin fixing screw 42 so as not to flow. The jig body 10 By fastening the bolt 43 to the tab hole 13 formed in the) to prevent the flow of the shelf chuck 20 is operated even if it rotates. When the setting is completed as described above, the inner tapered hole is processed through the through hole of the frame 45, and the outer surface is processed while the carrier is fixed.

이상에서 설명한 바와 같이 본 고안은 지그본체와 고정판을 이용하여 한 번의 셋팅으로 캐리어의 내경 테이퍼홀과 외경을 동시에 가공하여 양호한 동심도의 제품생산 및 공정수 절감으로 작업시간을 단축시킬 수 있는 매우 유용한 고안이다.As described above, the present invention is a very useful design that can shorten the working time by producing a good concentricity and reducing the number of processes by simultaneously processing the inner diameter taper hole and the outer diameter of the carrier by one setting using a jig body and a fixed plate. to be.
