본 고안은, 저항 용접기에 관한 것으로, 특히 가압 실린더를 안내하는 이코라이징(Equalizing)용 샤프트의 지지장치에 관한 것이다.The present invention relates to a resistance welding machine, and more particularly, to an apparatus for supporting an equalizing shaft for guiding a pressurized cylinder.

종래에는 한쌍의 지지부재에 제1, 제2의 전극을 서로 맞닿는 상태로 지지 시키어, 이 양 전극 사이에 피용접재의 겹친 부분을 끼어잡게 하여 용접하는 저항 용접기가 사용되고 있다.Conventionally, resistance welding machines are used in which a pair of supporting members are supported in a state in which the first and second electrodes are in contact with each other, and the welded portions are sandwiched between these electrodes by welding.

이 저항용접기에 있어서, 양 전극이 서로 근접 혹은 떨어지게끔, 한쪽의 전극을 고정한 지지부재를 가동아암으로 하고, 다른쪽의 전극을 고정한 지지부재를 고정아암으로 하고 있다.In this resistance welding machine, the supporting member on which one electrode is fixed is used as the movable arm, and the supporting member on which the other electrode is fixed is the fixing arm so that both electrodes are close to or separated from each other.

가동아암은 가압 실린더의 피스턴 로드에 고착되고, 다른쪽 고정아암은 그 가압 실린더의 실린더 케이스에 고착되어 있다.The movable arm is fixed to the piston rod of the pressure cylinder, and the other fixed arm is fixed to the cylinder case of the pressure cylinder.

그리고, 가압 실린더는, 아암 전체를 용접기 본체에 대하여 전진 혹은 후퇴를 할 수 있도록, 그 가압 실린더 케이스에 돌출되어 형성된 돌기편에 이코라이징용 샤프트가 끼어넣어져 있다. 이코라이징 샤프트는 한쌍의 "L"형 스테이(stay)에 의하여 용접기의 트랜스에 고정되어 있다.In the pressurizing cylinder, an ecorating shaft is inserted into a projection piece which protrudes from the pressurizing cylinder case so that the entire arm can be moved forward or backward with respect to the welder main body. The equalizing shaft is fixed to the transformer of the welder by a pair of "L" type stays.

그런데, 이런 종류의 저항용접기는, 그 설치장소가 통상, 다른 기구, 부품등이 다수 산재하고 있는 공장안에 있는 것이어서, 돌출 부분을 될 수 있는 대로 작게할 필요가 있다.By the way, this type of resistance welding machine is usually located in a factory scattered with a large number of different appliances, parts, etc., and therefore it is necessary to make the protruding portion as small as possible.

그렇지 않으면, 저항용접기를 이동시키는 경우에, 혹은 다른 기구, 부품등의 운반시에, 그 기구, 부품등이 돌출부분에 걸려서, 뜻하지 않은 사고사 일어날 수 있다.Otherwise, when the resistance welder is moved or when other instruments, parts, etc. are transported, the mechanisms, parts, etc. may be caught in the protruding portions, which may cause accidental accidents.

그리고, 종래의 저항용접기는, 이코라이징용 트랜스 측에서"L"형 스테이에 의하여 지지되어 있기 때문에 "L "형 스테이의 두께 만큼 및 "L" 형재를 고정하는 고정편의 두께만큼 돌출부분을 크게 하지 않으면 안되는 결점이 있었다.In addition, since the conventional resistance welding machine is supported by the "L" type stay on the side of the echo transformer, the protruding portion is not made larger by the thickness of the "L" type stay and the thickness of the fixing piece for fixing the "L" shape member. There was a defect that must be made.

본 고안은, 이와같은 문제점을 해결하기 위한 것으로서, 이코라이징용 샤프트의 트랜스로부터 돌출하는 높이를 작게하는 것과, 부품수를 줄이는 것을 목적으로 하고 있다.This invention aims at solving such a problem, and aims at reducing the height which protrudes from the transformer of an equalizing shaft, and reducing the number of components.

본 고안은, 상기 목적을 달성하기 위하여, 한쌍의 지지부재 앞끝단에 제1, 제2의 전극을 서로 맞닿는 상태로 지지시켜, 이 전극에 의하여 피용접재를 끼어 잡을 수 있게끔 상기 지지부재를 구동하는 가압 실린더를 가진 저항용접기에 있어서, 이 실린더 케이스에 형성한 돌기에 끼워 맞춤하는 이코라이징용 샤프트를, 트랜스의 양측판의 연장부에 설치한 것을 특징으로 한다.In order to achieve the above object, the present invention supports the first and second electrodes in contact with each other at the front end of the pair of supporting members, and drives the supporting members so that the welding member can be caught by the electrodes. A resistance welding machine having a pressurized cylinder, characterized in that an ecorating shaft fitted to a protrusion formed in the cylinder case is provided in an extension of both side plates of the transformer.

본 고안을, 도면에 의하여 구체적으로 설명하면 다음과 같다.The present invention will be described in detail with reference to the drawings.

제 1 도는, 본 고안의 1 실시예를 특징으로 한다.1 is characterized by one embodiment of the present invention.

트랜스(1)는, 양측부가 측판(2)에 의하여 덮혀서, 이 양측판(2)은 보울트(3)에 의하여 고정되어 있다.Both sides of the transformer 1 are covered by the side plates 2, and the two side plates 2 are fixed by the bolts 3.

그리고 양 측판(2)은 각각 연장부(2')가 형성되어 있다.And both side plates 2 are formed with extension parts 2 ', respectively.

이 양 측판(2)의 연장부(2')에 가압 실린더 안내용인 이코라이징용 샤프트(4)를 설치한다.In the extension part 2 'of these both side plates 2, the equalizing shaft 4 for pressure cylinder guidance is provided.

이 이코라이징용 샤프트(4),는 가압 실린더(5)의 둘레벽에 형성된 돌기(5')에 형성된 구멍을 관통하고 있으며, 가압 실린더(5)의 후퇴시에는 좌측의 돌기(5')가 측판(2)의 좌측 연장부(2')에 맞닿게 됨으로써 가압 실린더(5)가 더이상 후퇴하지 않게 되는 것이다.This economizing shaft 4 penetrates the hole formed in the projection 5 'formed in the circumferential wall of the pressure cylinder 5, and when the pressure cylinder 5 is retracted, the left projection 5' By contacting the left extension 2 'of the side plate 2, the pressure cylinder 5 no longer retracts.

또한, 공작물의 변이 또는 전극의 마모등에 의한 타점위치의 변경을 자동적으로 수정하여 용접을 가능하도록 한것이다.In addition, it is possible to automatically correct the change of the spot position due to the change of the workpiece or the wear of the electrode to enable welding.

도면 제 3 도는, 가압 실린더(5)에 용접하여 일체로한 돌기(5')측에 베어링(140을 형성함으로서 이코라이징용 샤프트(4)에서 가압 실리더(5)가 미끄럼 작동이 자유롭게 되어있다.FIG. 3 shows that the pressure cylinder 5 slides freely on the economizing shaft 4 by forming a bearing 140 on the protrusion 5 'side which is welded to the pressure cylinder 5 and integrated. .

그러나, 이에 한정하지 않고, 이코라이징용 샤프트(4)를 가압 실린더(5)와 함께, 트랜스(1)에 대하여 미끄럼 작동이 자유롭게 설계를 하여도 좋은 것이다.However, the present invention is not limited thereto, and the sliding shaft 4 may be designed to be freely slid with respect to the transformer 1 together with the pressure cylinder 5.

가압 실린더(5)의 피스턴 로드(6)에는 가동아암으로 되는 한쪽의 지지부재(7)를 고착하고, 다른쪽, 가압 실린더(5)의 실린더 케이스에는 고정아암으로 되는 다른쪽의 지지부재(8)를 고착한다.One support member 7 serving as a movable arm is fixed to the piston rod 6 of the pressure cylinder 5, and the other support member 8 serving as a fixed arm is attached to the cylinder case of the pressure cylinder 5. )).

이들 한쌍의 지지부재(7), (8)에는, 앞끝단에 각각 제1, 제2의 전극(9), (10)이 고정되어 있다.The first and second electrodes 9 and 10 are fixed to the pair of supporting members 7 and 8 at the front ends, respectively.

제1, 제2전극(9), (10)에는 트랜스(1)로부터 소정의 전류가 도체(11),(11)를 통하여 공급된다.A predetermined current is supplied from the transformer 1 to the first and second electrodes 9 and 10 through the conductors 11 and 11.

피용접재(A)가 소정의 용접기에 대하여 일정위치에 위치하게 되면, 가동아암(7)을 후퇴위치로부터 피용접재(A)를 향하여 전진 시키어, 피용접재(A)를 제1, 제2의 전극(9), (10)사이에 끼어 잡아 용접을 행하게 된다.When the to-be-welded material A is located in the predetermined position with respect to a predetermined welding machine, the movable arm 7 is advanced from the retracted position toward the to-be-welded material A, and the to-be-welded material A is made into the 1st, 1st The electrode is caught between the electrodes 9 and 10 of 2 to perform welding.

또한, 피용접재(A)가 소정의 위치에서 위치에서 벗어난 상태로 되면, 그벗어남에 상당하는 거리만큼 가압 실린더(5)를 전진 또는 후퇴 시키면서, 가동아암은 전자의 경우가 동일하게 구동하여 용접을 행하게 된다.In addition, when the to-be-welded material A comes out of the position from a predetermined position, the movable arm will drive and weld the same way as the former case, while advancing or retracting the pressurized cylinder 5 by the distance equivalent to the peeling off. Will be done.

이와같은 이코라이징용 샤프트 지지장치를, 도면 제 2 도에 도시된 종래의 지지장치와 비교하면, 본 고안은 그 구조가 간단하며, 또한 트랜스(1)로부터 가압 실린더(5)의 높이가 작아져 있는 것을 알수있다.Compared with the conventional support device shown in FIG. 2, the present invention has a simple structure and reduces the height of the pressurized cylinder 5 from the transformer 1. I can see that there is.

즉, 제 2 도에 도시된 종래의 지지장치에 있어서는, 이코라이징용 샤프트(4)가 "L"형 스테이(12)및 스테이 고정편(13)에 의하여 트랜스(1) 상면에 고정되어 있어 "L"형 스테이의 두께만큼 및 "L"형체를 고정하는 고정편의 두께만큼 돌출 부분을 크게 하여야만 했다.That is, in the conventional support device shown in Fig. 2, the economizing shaft 4 is fixed to the upper surface of the transformer 1 by the "L" type stay 12 and the stay fixing piece 13 ". The protruding portion had to be made large by the thickness of the L " stay and by the thickness of the fixing piece that fixed the “L” shape.

이것에 비교하여 본 고안의 실시예에 있어서는 이코라이징용 샤프트(4)가 트랜스의 측판(2)의 연장부(2')에 고정되어 있다.In comparison with this, in the embodiment of the present invention, the economizing shaft 4 is fixed to the extension 2 'of the side plate 2 of the transformer.

따라서, 본 고안에서는 별도의 스테이 및 그 고정편을 사용할 필요가 없고, 트랜스(1)의 양측을 덮는 측판(2)을 약간 연장한 것을 사용하는 것만으로 좋으며, 또한 가압 실린더(5)의 고정 높이도 스테이를 사용하지 않음으로 스테이의 두께 및 그 고정편의 두께만큼 낮게 할수가 있다.Therefore, in this invention, it is not necessary to use a separate stay and its fixing piece, it is only necessary to use the one which extends the side plate 2 which covers both sides of the transformer 1 slightly, and also the fixed height of the pressure cylinder 5 By not using a stay, the thickness of the stay and the thickness of the fixing piece can be as low as possible.

이상에서 상술한 바와같이, 본 고안에 있어서는 스테이 및 고정편을 사용하지 않고, 이코라이징용 샤프트(4)를 트랜스(1)의 양측에 착설한 측판(2)의 연장부(2')에 설치한 것이어서, 사용하는 부품 수가 적고 간단한 설계로 이코라이징용 샤프트(4)의 높이와, 나아가서는 가압 실린더(5)의 고정높이를 낮출 수가 있어서, 저항용접기의 취급에 있어, 돌출부분인 가압 실린더(5)의 주위에 형성되는 기구, 부품의 수도 적어지게 되어 작업성이 뛰어나게 된다.As described above, in the present invention, the economizing shaft 4 is installed on the extension portion 2 'of the side plate 2 mounted on both sides of the transformer 1 without using the stay and the fixing piece. As a result, the number of parts to be used is small and the design of the economizing shaft 4 and the height of the pressing cylinder 5 can be reduced by a simple design. The number of mechanisms and parts formed around 5) is reduced so that workability is excellent.

또한 측판(2) 자체가 트랜스(1)둘레벽에 비하여 강도적으로 강한 것이며, 조임공구에 의하여 양측판(2)이 트랜스(1)양측에 조여져 있어서 이코라이징용 샤프트(4)의 지지는 확실한 것이다.In addition, the side plate 2 itself is stronger in strength than the circumference of the transformer 1, and both sides of the plate 2 are fastened to both sides of the transformer 1 by a tightening tool, so that the support for the ecological shaft 4 is secured. will be.
