Description

대형 선박의 라다 설치용 이동식 테이퍼 홀 가공기{Portable tapered hole cutting machine for fastening rudder of a large ship}Portable tapered hole cutting machine for fastening rudder of a large ship}

본 발명은 대형 선박용 키를 조립하기 위해 테이퍼 홀의 내면을 고능률로 정밀하게 가공하는 이동식 장치에 관한 것이다.The present invention relates to a mobile device for high precision machining of the inner surface of a tapered hole for assembling a large marine key.

일반적으로 피가공물의 길이가 짧고, 무게가 가벼운 경우는 선반(Turning machine) 등에서 공구계를 경사 시키거나 또는 피가공물의 중심선과 회전 중심선을 편위 시키는 것으로 테이퍼 홀 가공을 달성하고 있다. 그러나 이러한 방법은 가공 정밀도와 공구의 마멸측면에서 좋지 못하고, 테이퍼의 양과 길이가 매우 작은 소형인 경우로만 제한된다. 특히 대형 선박용 키와 조타장치 연결 홀의 경우는 터닝머신에서 1차가공한 테이퍼 홀을 현장맞춤을 위해서, 작업자에 의한 핸드 그라인딩 공정(Hand grinding process)을 실시하고 있기 때문에 많은 시간과 비용을 소비하고 있다. 이러한 추가적인 핸드 그라인딩 공정은 제품의 가격을 상승시키고, 납기를 지연시키는 문제를 초래하고 있다. 따라서 대용량 테이퍼 홀의 가공이 가능하고, 정밀도가 우수하면서 현장에서 쉽게 적용할 수 있는 이동식 테이퍼 홀 가공기의 개발이 요구된다.In general, when the length of the workpiece is short and the weight is light, taper hole processing is achieved by tilting the tool system in a turning machine or by shifting the centerline and the rotation centerline of the workpiece. However, this method is not good in terms of machining precision and wear of the tool, and is limited to a small case where the amount and length of taper are very small. In particular, in the case of large ship keys and steering gear connecting holes, a hand grinding process is performed by the operator to fit the tapered holes first processed in the turning machine, which consumes a lot of time and money. . This additional hand grinding process raises the price of the product and causes the problem of delaying delivery time. Therefore, it is possible to process a large-capacity tapered hole, and the development of a mobile tapered hole machine that can be easily applied in the field while having excellent precision is required.

본 발명은 상기와 같은 문제점을 해소하기 위해서 이동식으로 대형 선박용 키와 조타장치 접속부의 테이퍼 홀을 정밀하게 가공할 수 있는 이동식 장치를 개발하여 기존의 터닝머신이나 보오링 머신 등에서는 가공이 불가능한 대형 공작물을 정밀하고 고능률로 가능할 수 있도록 하는데 본 발명의 목적이 있다.In order to solve the above problems, the present invention has developed a mobile device capable of precisely processing the taper hole of a large vessel key and steering gear connection by a mobile, and thus, a large workpiece that cannot be processed in a conventional turning machine or boring machine. It is an object of the present invention to enable the precise and high efficiency.

이를 위하여 본 발명은, 도 1에 나타낸 것과 같이 드럼형의 보오링 바(Drum type boring bar)가 밸트전동 및 차동기어열에 의해 회전운동을 하고, 보오링 바의 외면에 테이퍼 홀의 크기에 따라 3종류의 테이퍼 홀 가공용 해드를 설치할 수 있도록 하였다. 테이퍼 홀 가공용 헤드는 드럼형 보오링 바의 회전과 동일한 속도로 회전하면서, 무단변속이 가능한 교류 서보 모터(AC servomotor)와 리드스크류(Lead-screw)의 조합으로 경사면의 도브테일형 베드(Dove tail type bed)를 따라 직선이송운동이 제어된다. 테이퍼 홀 가공용 헤드에는 절삭공구를 장착하여 대형 홀의 내면을 고능률로 정밀하게 테이퍼 가공하는 것이 가능하다. 테이퍼 홀 가공에서는 이송운동의 정밀도가 매우 중요한 작업변수 이므로, 교류 서보 모터와 타이밍 벨트 시스템을 채용하여 정확한 이송량을 얻을 수 있도록 하였다.To this end, the present invention, as shown in Figure 1, drum type boring bar (Drum type boring bar) is rotated by the belt transmission and differential gear train, three types according to the size of the tapered hole on the outer surface of the boring bar The tapered hole machining head can be installed. The tapered hole processing head rotates at the same speed as the drum boring bar, and is a combination of an AC servomotor and a lead-screw capable of continuously variable speed. linear movement along the bed is controlled. The tapering hole machining head can be equipped with a cutting tool to precisely taper the inner surface of a large hole with high efficiency. In tapered hole machining, the accuracy of the feed motion is a very important work variable. Therefore, the AC servo motor and the timing belt system are adopted to obtain accurate feed amount.

또한 본 발명에서는 테이퍼 가공된 홀의 중심을 지나는 축에 수직인 평면의 가공(정면절삭)을 위한 정면 절삭장치(Facing attachment assembly)를 부착할 수 있도록 하였다. 이는 테이퍼 홀 가공전에 작업면의 선행가공 및 테이퍼 홀 가공후에 발생되는 버(Burr) 등을 제거하는데 매우 유용하다. 따라서 본 발명 장치를 이용하면 대형 테이퍼 홀 가공 및 테이퍼 홀에 수직인 평면의 복합가공이 가능하고, 현장에서 대형 홀의 가공 및 현장 맞춤조립을 위해 이동이 가능하도록 한 것이 특징이다.In addition, in the present invention, it is possible to attach a facing attachment assembly for the machining (frontal cutting) of the plane perpendicular to the axis passing through the center of the tapered hole. This is very useful for removing the burrs generated after the pre-machining of the working surface and the taper hole machining before the tapered hole machining. Therefore, the present invention is characterized in that the large tapered hole processing and the composite processing of the plane perpendicular to the tapered hole is possible, and the movement is possible for the processing of the large hole and the custom assembly in the field.

이와 같은 목적을 달성하기 위해서 본 발명은, 도 2에 나타낸 것과 같이 무단 변속이 가능한 교류서보모터(1)의 회전력을 정확하게 전달할 수 있도록 하기 위해서, 타이밍 밸트(2)를 이용하여 주이송축(3)에 전달하게 된다. 주이송축(3)의 회전력은 기어(4,5,6)에 의해서 두 개의 중간축(7,8)에 전달되고, 한개의 중간축(7)은 테이퍼 가공용 홀드(9,10,11)의 이송에 사용되고, 또 다른 중간축(8)은 정면절삭용 공구(12)의 이송에 이용된다. 도 4에 나타낸 것과 같이 테이퍼 가공용홀드(9,10,11)는 쉽게 탈·부착이 가능하고, 절삭공구(13)를 장착할 수 있어, 경사진 테이블(14)을 따라서 비스듬하게 설치된 리드스크류(15)의 이송운동과 경사테이블의 도브테일(16)의 안내를 받으며 이송이 가능해 진다. 이때 선박용 키홀에 사용되는 경사면(14)은 1/12와 1/15이므로 본 발명에서는 교환이 가능한 1/12와 1/15의 2개의 경사면(14)을 겸비하였다.In order to achieve the above object, the present invention, as shown in Figure 2, in order to be able to accurately transmit the rotational force of the AC servomotor (1) capable of continuously variable, the main feed shaft (3) using the timing belt (2) Will be delivered to The rotational force of the main feed shaft (3) is transmitted to the two intermediate shafts (7, 8) by the gears (4, 5, 6), and one intermediate shaft (7) of the tapered machining hold (9, 10, 11) Another intermediate shaft 8 is used for the transfer of the front cutting tool 12. As shown in FIG. 4, the tapered machining holders 9, 10, and 11 can be easily attached and detached, and the cutting tool 13 can be mounted thereon so that the lead screws are installed obliquely along the inclined table 14. The feeding movement of 15) and the guide of the dovetail 16 of the inclined table are enabled. At this time, since the inclined surface 14 used for the ship's keyhole is 1/12 and 1/15, in the present invention, the two inclined surfaces 14, 1/12 and 1/15, which can be exchanged, were combined.

한편 드럼형 보오링 바(17)의 회전운동은 절삭공구(13)의 이송과는 달리 일정한 회전속도를 유지하는 것이 필요하다. 따라서 범용 교류모터축(18)의 회전운동을 풀리(19,20)와 V-벨트(21) 및 기어(22,23)와 드럼형 보오링 바(17)의 외면에 설치된 기어(24)의 작용에 통해서 전달 할 수 있다. 이때 드럼형 보오링 바(17)의 회전력을 지지할 수 있도록 엥귤러롤러베어링(25)을 설치하였다. 이제 드럼형 보오링 바(17)의 회전운동과 테이퍼 가공용 홀드(9,10,11)가 경사면(14)을 따라서 이송운동 하는 것의 조합으로 원하는 테이퍼 홀의 내면을 가공할 수 있다. 이러한 구조를 통해서 본 발명은 충분한 강성과 정밀도를 확보할 수 있고, 가공 가능한 테이퍼 홀의 직경은560∼856까지 고능률로 정밀하게 절삭 가능하다. 또한 드럼형 보오링 바(17)는 테이퍼 홀을 가공하기 위해 미리 가공된 구멍에 삽입할 수 있어야 하기 때문에 도 5에 나타낸 것과 같이 드럼형 보오링 바(17)를 플런지(31)와 나사(32)를 이용해서 쉽게 분리 · 조립할 수 있도록 하였고, 이동시에는 아이볼트(33)를 이용하도록 하였다.On the other hand, the rotational movement of the drum-type boring bar 17 is required to maintain a constant rotational speed, unlike the transport of the cutting tool (13). Therefore, the rotational motion of the general-purpose AC motor shaft 18 of the gear 24 provided on the outer surface of the pulleys (19, 20) and the V-belt (21) and the gears (22, 23) and the drum type boring bar (17). Can be delivered through action. At this time, the roller roller bearing 25 was installed so as to support the rotational force of the drum-type boring bar 17. Now, the inner surface of the desired tapered hole can be machined by a combination of the rotational movement of the drum-type boring bar 17 and the tapered machining holds 9, 10, 11 moving along the inclined surface 14. Through this structure, the present invention can secure sufficient rigidity and precision, and the diameter of the tapered hole that can be machined is 560- It can cut precisely with high efficiency up to 856. In addition, since the drum-type boring bar 17 must be able to be inserted into a pre-machined hole in order to process a tapered hole, the drum-type boring bar 17 may be inserted into the plunge 31 and the screw ( 32) to be easily separated and assembled, and used to move the eye bolt (33).

또한 본 발명에서는 도 3에 나타낸 것과 같이 본 발명에서는 테이퍼 가공뿐만 아니라, 홀에 직각인 단면을 가공하는 정면절삭 장치(26)를 겸비하였다. 정면절삭 장치(26)는 교류 서보모터(1)의 회전운동을 중간축(8)과 기어(27,28)에 의해서 별도의 보조축(29)으로 전달되고, 이것이 정면절삭 장치(26)의 이송운동을 제어한다. 특히 정면절삭 가공직경의 변화에 따라서 정면절삭 공구홀드(30)의 위치를 조절할 수 있는 구조로 하였다. 이를 통해서 테이퍼 홀의 가공전에 가공물 표면의 선행가공과 테이퍼 홀 가공후 표면에 남게되는 버를 용이하게 가공할 수 있도록 하였다. 정면가공이 가능한 가공물의 직경범위는630∼1350까지 이다.In addition, in this invention, as shown in FIG. 3, in this invention, not only the taper process but the front cutting apparatus 26 which processes the cross section orthogonal to a hole was provided. The front cutting device 26 transmits the rotational motion of the AC servomotor 1 to the separate auxiliary shaft 29 by the intermediate shaft 8 and the gears 27 and 28, which is the front cutting device 26. Control the feed movement. In particular, the position of the front cutting tool holder 30 can be adjusted according to the change of the front cutting machining diameter. Through this, the pre-machining of the workpiece surface and the burr remaining on the surface after the taper hole processing can be easily processed before the taper hole processing. The diameter range of the workpiece that can be processed face 630- Is up to 1350.

본 발명의 결과로 대형 선박용 라다의 조립에 필요한 테이퍼 홀을 고능률로 정밀하게 가공할 수 있고, 테이퍼 홀에 직각인 면의 정면절삭이 가능해진다.As a result of the present invention, the tapered hole required for the assembly of the large ship ladder can be processed with high efficiency and precision, and the front face cutting of the surface perpendicular to the tapered hole can be performed.

이상에서 상술한 바와 같이 본 발명은, 대형 선박용 키와 조타장치를 연결하는 홀의 테이퍼 가공을 위한 것으로 종래의 방법으로는 1주일 이상 걸리던 가공 및 조립공정이 본 발명을 적용함으로써 3일 이내로 가능해 졌다. 이로서 생산성의 향상과 납기의 단축뿐만 아니라 대형 테이퍼 홀의 가공 신뢰성 확보가 가능해 졌다. 또한 본 발명을 이용하면 테이퍼 가공뿐만 아니라, 테이퍼 홀의 축에 수직인 단면을 가공하는 정면절삭이 가능하여, 테이퍼 홀의 가공전에 가공물의 선행가공이나, 테이퍼 홀 가공후 버 등의 가공을 위한 별도의 가공기가 필요치 않다.As described above, the present invention is for tapering a hole connecting a large ship's key and a steering device, and a machining and assembling process, which took more than one week in the conventional method, can be performed within three days by applying the present invention. This not only improves productivity and shortens delivery times, but also secures processing reliability for large tapered holes. In addition, the present invention enables not only taper processing, but also front face machining of the cross section perpendicular to the axis of the tapered hole, and thus a separate processing machine for the pre-processing of the workpiece before the tapered hole is processed, or the burr after the tapered hole processing. Is not necessary.
