종래 속이 움푹 패인 형태의 벨마우스와 같은 벨마우스부재를 송풍기 측면에 고정하기 위해서는 그 연부를 따라 볼트공을 천공하고 있다.Conventionally, in order to fix a bell mouse member such as a bell mouse having a hollow shape on the side of the blower, a bolt hole is drilled along the edge thereof.

그런데 이와같은 볼트공의 천공작업은 작업자들이 일일이 구조물을 들고 천공기에 넣고 한개 펀칭후 다른 한개를 돌려주고 하는 과정을 수공으로 일일이 작업해야하는 번거로움이 있었다.However, the drilling of bolts like this has been a hassle that workers have to carry out the process of manually carrying the structure by putting the structure into the perforator and punching one and returning the other.

이와같은 수공적인 제조공정은 많은 작업인원이 동원되야 하므로 인건비 증가를 초래하며, 수가공으로 인해 제조기간이 길어지고, 일일이 수작업을 하므로 작업효율도 좋지 않았다.This manual manufacturing process has to increase labor costs because a large number of workers must be mobilized, the manufacturing period is long due to the process, and the work efficiency is not good because of manual work.

특히, 이와같은 천공장치에 있어서 최근에는 벨마우스부재가 벨마우스와 같이 원형의 형태를 갖는 경우 주로 회전되는 받침틀위에 놓여지도록 구성하나, 원형의 벨마우스부재를 원형받침틀위에 놓고 천공하는 경우 유동되는 문제점이 있다.In particular, in such a puncturing device, in recent years, when the bell mouse member has a circular shape, such as a bell mouse, it is configured to be placed on a supporting frame that is mainly rotated, but a problem that flows when a circular bell mouse member is placed on a circular support frame and perforated There is this.

이를 해결하기 위하여 종래에는 원형받침틀위에 가용접을 한 뒤 천공작업을 하여 왔다.In order to solve this problem, conventionally, the welding process is carried out after welding on a circular support frame.

그러나 천공이 완료된 벨마우스부재에 형성된 용접찌꺼기를 일일이 다시 수작업으로 제거해야 하는 문재점을 초래하였다.However, this resulted in a problem that the welding residue formed on the bell mouse member was completed by manual removal.

따라서 벨마우스와 같은 원형의 벨마우스부재의 천공시에는 상방에서 이를 지지하여주는 지지수단이 필요로 되는 것이다. Therefore, when drilling a circular bell mouse member such as a bell mouse is required to support it from above.

본 발명의 목적은 송풍기의 벨마우스와 같은 벨마우스부재의 연부에 원형으로 일주형성되는 체결공을 가공하는 천공장치의 벨마우스부재를 견고하게 상방에서 지지해주는 지지장치를 제공하는 데에 그 목적이 있다.An object of the present invention is to provide a support device for firmly supporting the bell mouse member of the punching device for processing a fastening hole formed in a circle around the edge of the bell mouse member, such as the bell mouse of the blower. have.

이와같이 구성된 본 발명의 작동을 첨부 도면 도 4b에서 도시하는 바에 의거설명하면 다음과 같다.The operation of the present invention configured as described above will be described with reference to FIG. 4B as follows.

상기 수개의 링형단턱들(272)이 다수 원형으로 형성된 회전체(270)위에 벨마우스형 벨마우스부재를 재치시키고, 그 위에서 벨마우스부재를 실린더(412)를 작동시켜 롯드(414)를 하강시켜 공회동되는 지지원판(440)을 벨마우스부재상방에서 가압지지한다. 지지원판(440)은 공회동되므로 상기한 받침틀(280)이 회전하더라도 벨마우스부재의 압착상태를 견고하게 유지시킨다. 이 상태에서 회전체(270)하방의 이동체(340)을 본체(100)측으로 이동시킨다. 이때 스크류바(320)는 회전함으로써 이동체(340)에 이동력을 가하고, 슬라이드바(332,334)는 이동체(340)양측을 받친 가운데 미끄럼이동되게 한다.The bell-shaped bell mouse member is placed on the rotating body 270 in which the several ring-shaped jaws 272 are formed in a plurality of circles, and the bell mouse member is operated by the cylinder 412 to lower the rod 414. The idle supporting support plate 440 is pressed and supported above the bell mouse member. Since the support disc 440 is co-rotated, the crimping state of the bell mouse member is firmly maintained even when the support frame 280 rotates. In this state, the moving body 340 below the rotating body 270 is moved to the main body 100 side. At this time, the screw bar 320 rotates to apply a moving force to the moving body 340, the slide bar (332, 334) is to be sliding in the middle of supporting both sides of the moving body (340).

본체(100)의 작업대(140)에 근접한 벨마우스부재의 높이를 조정하기 위하여 상기 이동체(340)위 수직이동판체(230)를 상하동함이 필요하다.In order to adjust the height of the bell mouse member adjacent to the work bench 140 of the main body 100, it is necessary to vertically move the vertical plate 230 on the movable body 340.

즉, 회전손잡이(262)를 정역 조절하면서 회전시켜 수직이동판체(230)의 높이를 맞추면 그 위에 설치된 구동모터(250)와 감속기(260)와 회동체(270)와 받침틀(280) 및 벨마우스부재가 수직방향의 높이가 상하 조정된다. 이때 작업대(140)위의 펀칭받침대(130)의 높이를 고려하여 높이가 결정된다.That is, by rotating the rotary knob 262 while adjusting the normal and reverse to match the height of the vertical movable plate 230, the drive motor 250 and the reducer 260 and the rotating body 270, the support frame 280 and the bell installed thereon The height of the mouse member in the vertical direction is adjusted up and down. At this time, the height is determined in consideration of the height of the punching support 130 on the worktable 140.

이와같이 펀칭용 벨마우스부재의 높이가 작업하기 위한 높이로 결정되면 수직펀칭용실린더(110)를 하강시켜 천공하기 위한 준비를 한다.As such, when the height of the punching bell mouse member is determined as the height for the work, the vertical punching cylinder 110 is lowered to prepare for drilling.

먼저 펀칭받침대(130)의 양측 장공(132)에 볼트머리가 아래로 가도록 볼트(부호생략)관통시킨 뒤 상부에서 너트(부호생략)를 느슨하게 체결한다. 양측 볼트머리를 작업대(140)의 전면에서 가이드흠(142)에 맞추어 밀어넣는다. 밀어넣어진 펀칭받침대(130)의 직상부에 수직펀칭용실린더(110)의 펀칭부(120)펀치(122)가 오도록 맞춘다. 이때 받침부(130)는 장공(132)을 통하여 너트를 풀어 좌우간격을 조정함과 동시에 전후간격을 조정한 뒤 꽉 조여 고정한다.First, bolts (not shown) penetrate the bolt heads to both side holes 132 of the punching support 130, and then loosely tighten nuts (not shown) from the top. Both bolt heads are pushed into the guide grooves 142 at the front of the work table 140. The punching part 120 of the vertical punching cylinder 110 is aligned so that the punch 122 comes in the upper portion of the punched support base 130 pushed in. At this time, the support unit 130 is fixed by tightening after adjusting the front and rear intervals at the same time to release the nut through the long hole 132 and at the same time.

이 상태에서 펀칭작업대(130)의 상면에 위치한 벨마우스부재의 연부를 따라 정해진 위치에 수직펀칭용실린더(110)를 하강시켜 체결공을 펀칭하는 것이다. 이어서 벨마우스부재의 다음 위치를 찾아 벨마우스부재를 소정각도 회전시켜 같은 작동을 반복하는 것이다.In this state, the vertical punching cylinder 110 is lowered at a predetermined position along the edge of the bell mouse member located on the upper surface of the punching work 130 to punch the fastening hole. Subsequently, the same operation is repeated by finding the next position of the bell mouse member and rotating the bell mouse member by a predetermined angle.

벨마우스부재의 각도 회동은 상술한 구동모터(250)와 감속기(252)의 구동에 따른다.The angle rotation of the bell mouse member depends on the driving of the driving motor 250 and the reduction gear 252 described above.

이상 설명한 바와같이 본 발명 벨마우스부재를 천공하기 위한 장치의 지지장치는 그동안 일일이 받침틀위에 벨마우스부재를 가용접함에 따른 마무리 가공의 불편함을 개선한 효과를 가지며, 수작업으로 회전시키면서 체결공을 가공하던 가공과정을 간소화하여 작업자 한사람의 간단한 기기조작으로 다수의 벨마우스부재의 체결공 천공작업이 간소화하게 되었다.As described above, the support device of the device for drilling the bell mouse member of the present invention has the effect of improving the inconvenience of finishing processing by welding the bell mouse member on the support frame during the day, and processes the fastening hole while rotating by hand By simplifying the machining process, a simple machine operation by each worker simplifies the drilling of fastening holes for a number of bell mouse members.
