Abstract
본 고안은 밀링머신용 조립식 롱아버(Long Arbor)에 관한 것이다. 종래 밀링머신용 롱아버의 경우에는 헤드와 축이 상호일체로 가공되어 있어서, 밀링머신 가공중의 진동이나 충격으로 축이 휠 경우 헤드와 축전체를 교체해야 했었다. 이로 인하여 사용자에는 가중한 교체 부담을 갖게 된다.The present invention relates to a prefabricated Long Arbor for a milling machine. In the case of the conventional long arbor for a milling machine, the head and the shaft are integrally processed, and the head and the whole shaft had to be replaced when the shaft was wheeled due to vibration or impact during the milling machine. This causes a heavy replacement burden on the user.
이에 본 고안에서는 헤드(1)와 롱아버축(2)이 상호 분리결속되도록 한 것으로서 헤드(1)내의 축삽입설치공(1a)에 로킹엘레먼트(8)을 끼워넣고 롱아버축(2)을 끼운 후 잠금너트(3)의 브라켓트(1b)를 풀림방지볼트(7)로 단단히 조여붙이게 됨을 특징으로 하는 밀링머신용 조립식 롱아버.In the present invention, the head 1 and the long arbor shaft 2 are to be separated from each other, and the locking element 8 is inserted into the shaft insertion hole 1a in the head 1, and the long arbor shaft 2 is inserted. Prefabricated long arbor for the milling machine, characterized in that the bracket (1b) of the lock nut (3) is tightened tightly with a loosening prevention bolt (7).

본 고안은 밀링머신용 조립식 롱아버(Long Arbor)에 관한 것으로서, 특히 사용중 롱아버축이 휘어 센터가 잡히지 않을 때 롱아버축만 교체함으로서 부대원가를 대폭절감 하도록 하는데 그 목적이 있다.The present invention relates to a prefabricated long arbor for a milling machine, and in particular, its purpose is to significantly reduce the unit cost by replacing only the long arbor shaft when the long arbor shaft is not bent during use.
일반적으로 밀링머신의 밀링커터 작업시 롱아버축에 각종 밀링커터를 단단히 조여붙여 절삭작업을 수행하는데 있어서, 롱아버축과 헤드가 일체로 가공되여 있어서, 사용도중 롱아버축이 휘어 정도(precision)가 흐트러질 때 상기 롱아버축과 헤드가 일체구조로 된 롱아버(Long Arbor) 전체를 교체해야 되는 낭비를 초래하였었다.In general, in the milling cutter operation of the milling machine, various milling cutters are tightly fastened to the long arbor shaft, and the long arbor shaft and the head are integrally machined, so that the long arbor shaft is bent during use. When the long arbor shaft and the head was integrated, the long arbor (Long Arbor), which is integrally structured, had to be replaced.
일반적으로 롱아버축과 헤드의 가공원가 구성비를 보더라도 헤드의 가공원가비가 월등히 높기 때문에 절삭작업중 롱아버축(2)이 휘어, 정도(precision)가 흐트러진 경우 일체구조로 된 롱아버축과 헤드를 폐기해야 하는 낭비적인 요인이 있었다. 이에 본 고안은 상기의 점을 감안하여 안출한 것으로서, 이하 첨부된 도면에 의해서 본 고안의 구성 및 작용효과를 알아보면 다음과 같다.In general, even if the cost ratio of the long arbor shaft and the head is very high, the processing cost of the head is very high, so if the long arbor shaft 2 is bent during the cutting operation and the precision is disturbed, the long arbor shaft and the head of the integrated structure are discarded. There was a wasteful factor to do. The present invention is devised in view of the above point, when the configuration and operation effects of the present invention by the accompanying drawings as follows.
제1도면에서는 본 고안의 일실시 사용상태 참고사시도로서, 통상의 밀링머신(200)에 장착되여 사용되는 롱아버축(2)에 밀링커터(9)를 단단히 조여붙여 사용함을 도시한 참고사시도이다.1 is a reference perspective view of one embodiment of the present invention, a reference perspective view showing that the milling cutter 9 is firmly fastened to the long arbor shaft 2 used in a conventional milling machine 200. .
제2도는 본 고안 롱아버(100)의 외관시시도로서, 원추형으로 된 헤드(1)와 롱아버축(2)이 풀림방지볼트(7)로 잠금너트(3)에 의해 조립되며 상기 롱아버축(2)에는 4조의 부싱(5,5a,5b,5c)이 축설치되며, 이 롱아버축(2) 끝단에도 고정텝(4)이 풀림방지볼트(7)로 고정된 것으로서, 이하 제3도 및 제4도에 도시된 롱아버(100)의 분해조립 사시도와 요부단면도에 의해 상세히 알아보면 축삽입설치공(1a)이 형성된 외주연이 브라켓트(1b)으로 된 헤드(1)와 상기 롱아버축(2)두를 일체로 결속함에 있어서, 상기 축삽입설치공(1a)내에 로킹엘레먼트(8)을 끼워 설치한 후 롱아버축(2)두를 축설치하여 로킹엘레먼트(8)의 두 요소가 롱아버축(2)을 단단히 조여지도록 잠금너트(3)을 끼워 풀림방지볼트(7)로 조여붙인 것이다. 상기와 같이 구성된 본 고안의 작용상 효과를 알아보면 다음과 같다.2 is an external appearance of the long arbor 100 of the present invention, in which the head 1 and the long arbor shaft 2, which are conical, are assembled by the lock nut 3 with the loosening prevention bolts 7 and the long arbors. Four sets of bushings (5, 5a, 5b, 5c) are installed in the shaft (2), and the fixing step (4) is fixed to the end of the long arbor shaft (2) by the loosening prevention bolt (7). When the detailed view of the long arbor 100 shown in Figures 4 and 4 by the exploded assembly perspective and main cross-sectional view, the head (1) and the long periphery of the outer periphery of the shaft insertion installation hole (1a) is formed of the bracket (1b) In uniting the two arbor shafts (2) integrally, the locking element (8) is inserted into the shaft insertion hole (1a) and then installed, and the two long arbor shafts (2) The fastening bolts (7) are fastened by inserting the lock nut (3) so that the elements tighten the long arbor shaft (2). Looking at the effect of the present invention configured as described above are as follows.
첨부도면 제4도에 각 도시된 바와 같이 헤드(1)의 축삽입설치공(1a) 외측연에 로킹엘레먼트(8)을 끼운 후 이 로킹엘레먼트(8)내에 롱아버축(2)을 통과한 것으로, 헤드(1)의 브라켓트(1b)에 잠금너트(3)의 로킹엘레먼트조임돌부(3a)가 상기 로킹엘레먼트(8)의 내접요소를 단단히 조여 헤드(1)의 축삽입설치공(1a) 외측연에 로킹엘레먼트(8)를 끼운 후, 이 로킹엘레먼트(8)내에 롱아버축(2)을 통과한 것으로, 헤드(1)의 브라켓트(1b)에 잠금너트(3)을 마주붙여 풀림방지볼트(7)로 단단히 조이면, 잠금너트(3)의 로킹엘레먼트조임돌부(3a)가 상기 로킹엘레먼트(8)의 내접요소를 단단히 조여 헤드(1)의 축삽입설치공(1a) 내벽에 단단히 조여져, 상기 잠금너트(3)와 헤드(1)의 두요소가 일체로 조립되는 것으로서, 분해는 제4도(b)와 같이 잠금너트(3)의 풀림방지볼트(7)을 각 해체하여 로킹엘레먼트(8)의 내접요소에 가해진 잠금너트(3)의 로킹엘레먼트조임돌부(3a)를 해체시켜 헤드(1)와 롱아버축(2)을 분리하는 것이다.As shown in FIG. 4, the locking element 8 is inserted into the outer edge of the shaft insertion hole 1a of the head 1, and then the long arbor shaft 2 passes through the locking element 8. The locking element fastening protrusion 3a of the locking nut 3 is tightened to the bracket 1b of the head 1 so that the internal element of the locking element 8 is tightly tightened, and the shaft insertion installation hole 1a of the head 1 is secured. The locking element 8 was inserted into the outer edge, and then passed through the long arbor shaft 2 in the locking element 8. The locking nut 3 was attached to the bracket 1b of the head 1 to prevent loosening. When the bolt 7 is tightened firmly, the locking element tightening protrusion 3a of the lock nut 3 tightens the internal element of the locking element 8 to the inner wall of the shaft insertion hole 1a of the head 1. The two components of the lock nut 3 and the head 1 are integrally assembled, and disassembly is performed by disassembling the loosening prevention bolts 7 of the lock nut 3 as shown in FIG. By dismantling the locking elements & fastening protrusion (3a) of the locknut (3) applied to the internal elements of the locking elements & (8) to separate the head 1 and a long arbor shaft (2).
상기와 같이 본 고안에서는 헤드(1)와 롱아버축(2)이 상호 자재로 이 결속·분리될 수 있기 때문에 밀링머신(200)에 결속되어 절삭작업을 수행하는 가운데 절삭물에 부딪힌 충격이나 진동으로 롱아버(100)의 정도(precision)가 흐트러질 경우 롱아버축(2)만을 교체사용하는 것이다. 따라서, 종래 헤드(1)와 롱아버축(2) 일체를 교체하는 것보다는 롱아버축(2)만을 교체함으로서, 약 15%의 원가만으로도 밀링머신의 롱아버축(2)을 교체할 수 있는 것으로서 그 사용상 효과가 매우 유용한 고안인 것이다.As described above, in the present invention, since the head 1 and the long arbor shaft 2 can be bound and separated by mutual materials, they are bound to the milling machine 200 to impact or vibrate against the workpiece while cutting. As long as the precision of the long arbor 100 is disturbed, only the long arbor shaft 2 is used. Therefore, by replacing only the long arbor shaft 2 rather than replacing the conventional head 1 and the long arbor shaft 2, the long arbor shaft 2 of the milling machine can be replaced with only about 15% of the cost. As a use effect is a very useful design.
