본 고안은 예를 들어 덤프트럭의 적재함을 올리는 유압호이스트 실린더튜브의 보링장치에 관한 것이다.The present invention relates to, for example, a boring device for a hydraulic hoist cylinder tube for raising a dump truck loading box.
종래 이와 같은 실린더 튜브 가공장치로서 사용하고 있는 것은 제5도와 같이 파이프 내면이나 실린더 내면을 가공하는 방법과 같이 선반척에 실린더튜브 일단을 물리고 다른 한쪽은 회전될 수 있도록 방진구로서 물려서 잡아준 후 공구대의 바이트를 길게 연장하여 실린더 내면에 ㄱ자로 꺽어 삽입하여 튜브 내면을 1/2정도 가공한 후 물린 것을 모두 풀고 다시 반대로 물려 나머지를 가공하고 있으므로 실린더튜브 외면이 방진구와 마찰하여 회전함으로 회전 안내흠집이 발생되게 되고 2회 작업으로 인한 선반척의 세팅이 까다롭고 시간이 지연되며 정밀한 가공 또한 불가능한 것이다.Conventionally, such a cylinder tube processing apparatus is used to bite one end of the cylinder tube on a lathe chuck and to hold the other side as a dustproof opening so that the other side can be rotated as in the method of processing the inner surface of the pipe or the cylinder as shown in FIG. By extending the bite and inserting it into the cylinder with a letter B, the inner surface of the tube is processed about 1/2, and then all the bites are removed and the other bit is processed by the reverse bit. The lathe chuck setting is difficult, time-delayed and precise machining is impossible due to the two-time operation.
본 고안은 선반의 왕복대 위에 베이스플레이트를 부착하고 그 위에 각종 지그를 고정하여 실린더 튜브를 고정한 후 선반척과 연결된 척킹바, 유니버셜죠인트 및 보링바를 회전시켜 보링바에 설치한 바이트에 의해 실린더를 1회 작업으로 가공하게 함으로서 제품에 흠이 없고 세팅시간이 간단하고 시간이 단축되게 한 장치를 창출한 것이다.The present invention attaches the base plate to the shelf of the shelf and fixes various jigs on it to fix the cylinder tube, and then rotates the chucking bar, universal joint and boring bar connected to the lathe chuck to work the cylinder once by the bite installed on the boring bar. It is a device that makes the product free from scratches, the setting time is simple, and the time is shortened.
이하 고안의 요지를 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the gist of the present invention will be described in detail with reference to the accompanying drawings.
왕복대 베이스플레이트(1) 위에 클램프(2)와 후론트 스테리레스트(3)를 설치하고 그 뒤에는 블록(4), (4')를 설치하여 그 중간에 클램핑 픽스쳐(5)를 설치하며 선반척(6)에 척킹바(7)를 물려 놓고 보링바(10)를 기기외부에서 가공할 실린더튜브(13) 내에 끼워서 실린더튜브(13)는 클램핑 픽스쳐(5)에 위치 고정하고 보링바(10)는 선단에서 유니버셜죠인트(8)로 척킹바(7)에 연결하고 뒤쪽은 스테리레스트(11)에 축설시킨 구조이다.Install the clamp (2) and the front steric rest (3) on the carriage base plate (1), and then block (4) and (4 '), install the clamping fixture (5) in the middle of the shelf chuck. (6) and chucking bar (7) by inserting the boring bar (10) into the cylinder tube 13 to be machined outside the machine, the cylinder tube 13 is fixed to the clamping fixture (5) and the boring bar (10) to the tip In the universal joint (8) to the chucking bar (7) connected to the rear is sterilized in the structure (11).
미설명부호 12는 스포트, 14는 보조플레이트이다.Reference numeral 12 denotes a spot and 14 an auxiliary plate.
이와 같이 된 본 고안은 보링할 실린더튜브(13)를 기기 외부의 장소에서 미리 수공으로 보링바(10) 외부로 끼워 블록(4) 위에 얹어놓고 클램핑 픽스쳐(5)를 상하 승강시켜 실린더 튜브(13)를 보링바(10)의 바이트(9)의 회전중심과 맞춰 세팅한 수 선반척을 작동시켜 보링바(10)를 회전시키면 보링바(10)는 클램프(2)와 후론트스테디레스트(3) 및 리어레스트(11)에 의하여 정밀하게 회전하게 된다.According to the present invention, the cylinder tube 13 to be bored is inserted into the boring bar 10 by hand in a place outside the machine in advance and placed on the block 4 and the clamping fixture 5 is moved up and down to the cylinder tube 13. When the boring bar 10 is rotated by operating the turning lathe chuck set in accordance with the rotation center of the bite 9 of the boring bar 10, the boring bar 10 is clamped (2) and front steady rest (3) and rear rest ( 11) to rotate precisely.
이때 왕복대를 이동시키면서 가공을 행하게 되면 실린더 튜브(13)의 끝단까지 1회 작업으로서 내며 보링을 실시할 수 있는 것이다.At this time, if the machining is carried out while moving the carriage, it is possible to perform boring while giving out one operation to the end of the cylinder tube 13.
또한 제4도의 (a)와 같이 실린더튜브(13)의 외경이 블록(4)의 외경과 같을시는 직접 고정시켜 내부 가공을 하고 이보다 외경이 작은 실린더튜브(13)일 경우에는 블록(4)의 외경과 가공할 실린더 튜브(13)와의 크기에 대한 편차를 보조플레이트(14) 등을 블록(4)의 외면에 끼워 넣어 보링바(10)의 중심에 일치되도록 하여 가공하는 것으로서 각기 다른 외경을 갖는 실린더튜브를 가공할 수 있는 것이다.In addition, when the outer diameter of the cylinder tube 13 is the same as the outer diameter of the block 4 as shown in FIG. 4 (a), the internal processing is performed by directly fixing the block 4 in the case of the cylinder tube 13 having a smaller outer diameter. The outer plate and the size of the cylinder tube 13 to be machined by inserting the auxiliary plate 14 and the like into the outer surface of the block 4 so as to be coincident with the center of the boring bar 10 and having different outer diameters. The cylinder tube can be processed.
그러므로 본 고안은 종래 선반에서 실시하던 세팅이 2중성으로 인한 작업지연과 난이성 및 정밀도 저하를 배제함으로서 품질향상과 작업 능률화에 기여하는 효과가 있는 것이다.Therefore, the present invention has the effect of contributing to the improvement of quality and the efficiency of work by excluding the work delay, difficulty, and deterioration of precision due to the dual setting.
