등록특허공보 제417807호(2001. 9. 27. 출원, 2004. 1. 27. 등록, 이하 '종래기술'이라 함)Registered Patent No. 417807 (filed Sep. 27, 2001, Jan. 27, 2004, hereinafter referred to as 'prior art')

본 발명은 전동식 핸드리벳건에 관한 것으로, 더 구체적으로는 전원을 인가하는 트리거의 작동만으로 리벳접합이 가능하므로 작업자의 피로감을 줄일 수 있음은 물론, 리벳접합을 위한 구동모터의 구동방향이 한 방향으로 일관되게 이루어지도록 함으로써, 전기적인 부하(負荷) 등에 따른 내구성 저하를 방지할 수 있는 전동식 핸드리벳건에 관한 것이다.The present invention relates to an electric hand rivet gun, and more specifically, since riveting is possible only by the operation of a trigger for applying power, it is possible to reduce the fatigue of the operator, and the driving direction of the driving motor for the riveting is one direction. The present invention relates to an electric hand rivet gun that can prevent durability deterioration due to electrical load or the like by being made consistently.

일반적으로 리벳접합은 공작이 수월하고, 접합부의 강도도 강해서, 건축물이나 보일러, 다리, 선박, 가스탱크 및 보도교 등에 널리 사용된다. 리벳접합시 사용하는 리벳건 특히, 접합하고자 하는 판재에 뚫려 있는 구멍에 리벳을 꽂아 넣고, 머리 부분에 변형을 가하는 수동형 리벳건의 경우, 작업자가 손아귀 힘으로 가압해야 하는 구성으로, 작업이 진행될수록 작업자의 피로가 과중(過重) 될 수밖에 없 고, 피로에 따른 접합불량은 곧 리벳의 낭비로 이어지는 등의 문제점이 있었다.In general, rivet joints are easy to work with and the strength of the joints is strong, so they are widely used in buildings, boilers, bridges, ships, gas tanks and walkways. Rivet guns used for rivet joining In particular, a manual rivet gun that inserts a rivet into a hole drilled in a plate to be joined and deforms the head part, has to be pressurized with a hand grip, and as the work progresses, Fatigue was forced to be heavy (수 重), and there was a problem that the joint failure due to fatigue soon leads to waste of rivets.

이러한 문제점을 해결하기 위한 것으로, 상기한 종래기술의 문헌 정보에 기재된 자료에서와 같은 기술이 개시되어 있다. 상기한 종래기술은 작업성 개선을 위한 핸드리벳건의 자동 트리거장치에 관한 것으로, 대체적인 기술구성은 아래와 같다.In order to solve such a problem, the same technique as in the document described in the above-mentioned prior art document is disclosed. The prior art relates to an automatic trigger device of a hand rivet gun for improving workability, and an alternative technical configuration is as follows.

도 1에서 도시한 바와 같이, 종래기술에 따른 핸드리벳건의 자동 트리거장치는, 트리거스위치(1)가 구비된 총신(2)에 탈착 또는 장착 가능한 것으로, 센서하우징(3), 푸셔브래킷(4), 리턴스프링(5), 푸셔가이드(6) 및 조절나사(7) 등으로 구성된다.As shown in FIG. 1, the automatic trigger device of the hand rivet gun according to the related art is detachable or attachable to the barrel 2 provided with the trigger switch 1, and includes a sensor housing 3 and a pusher bracket 4. , Return spring (5), pusher guide (6) and adjusting screw (7).

상기 종래기술은 소정의 트리거스위치(1)가 구비된 핸드리벳건의 총신(2)에 센서하우징(3) 및 푸셔브래킷(4) 등으로 구성된 자동 트리거장치를 장착함으로써, 힘이 약한 여성 작업자들도 양질의 리벳접합이 가능한 등 작업성을 개선하는 일부 효과가 발휘된다. 그러나 특정 형태의 트리거스위치(1)가 없는 핸드리벳건에서는 무용지물일 수밖에 없다. 즉, 종래기술은 조절나사(7)와 연계되는 트리거스위치(1)에 의해 푸셔브래킷(4) 및 센서하우징(3)이 작동되는 것으로, 적용 가능한 대상이 특정 형태에 한정될 수밖에 없는 문제점을 안고 있다.The prior art is equipped with an automatic trigger device consisting of a sensor housing (3) and a pusher bracket (4) on the barrel (2) of the hand rivet gun equipped with a predetermined trigger switch (1), so that even women with weak force Some effects to improve workability, such as good quality rivet joining, can be achieved. However, in the hand rivet gun without a specific type of trigger switch (1) is obsolete.

도 2에서처럼 본 발명은 총구(91)에 노우즈(10)가 구비되고, 총열(92) 속에 는 리벳의 핀을 붙잡아 인장력을 가하는 홀드부재(20)와, 이 홀드부재(20)에 의한 리벳 핀의 인장상태를 해지하기 위한 소정 형태의 해지수단(30)이 구비된 통상의 핸드리벳건 형태를 포함한다. 홀드부재(20)는 적어도 두 개로 형성된 조각체 형태로 이루어진다.2, the present invention is provided with a nose 10 in the muzzle 91, the holding member 20 to apply a tensile force by holding the pin of the rivet in the barrel 92, and the rivet pin by the holding member 20 It includes a conventional hand rivet gun form provided with a termination means 30 of a predetermined form to terminate the tension state of the. The holding member 20 is formed in the form of a sculpture formed of at least two.

특히, 본 발명은 전원을 인가하는 일종의 스위치에 해당하는 트리거(93)에 의해 작동되는 구동모터(40)를 구비하되, 이 구동모터(40)의 구동축 상에 소정 형태의 플라이휠(41)을 구비하고, 여기에 맞물려 회동하는 휠부재(60)도 구비된다. 이때, 휠부재(60)는 플라이휠(41)보다 사이즈를 크게 함으로써, 구동모터(40)의 해당 출력 대비 추진력을 크게 할 수 있는 형태가 좋다.In particular, the present invention includes a drive motor 40 operated by a trigger 93 corresponding to a kind of switch for applying power, and having a flywheel 41 of a predetermined type on a drive shaft of the drive motor 40. In addition, the wheel member 60 is also provided to engage and rotate. In this case, the wheel member 60 may have a larger size than the flywheel 41, so that the driving force of the wheel member 60 may be increased compared to the corresponding output of the driving motor 40.

그리고 총열(92)의 내주면에는 미끄러지면서 홀드부재(20)를 끌어당길 수 있도록 견인부재(50)를 구비하되, 휠부재(60)와 연계된 작동링크(70)와 힌지 형태로 결합되어 견인부재(50)의 전진 또는 후퇴가 가능한 형태로 구비된다. 즉, 한쪽 끝단은 휠부재(60)의 원주단과, 다른쪽 끝단은 견인부재(50)와 각각 힌지 형태로 체결된 작동링크(70)에 의해 휠부재(60)의 회전운동을 직선왕복운동으로 전환함으로써, 견인부재(50)는 소정 거리를 왕복하게 된다.In addition, the inner circumferential surface of the barrel 92 is provided with a traction member 50 so as to pull the holding member 20 while sliding, coupled to the operation link 70 and the hinge form associated with the wheel member 60 in the form of a traction member It is provided in the form which can move forward or backward of 50. That is, one end is the circumferential end of the wheel member 60, the other end is a linear reciprocating motion of the rotational movement of the wheel member 60 by the operation link 70 is fastened to the traction member 50 in the hinge form respectively By switching, the towing member 50 reciprocates a predetermined distance.

해지수단(30)은 총열(92) 내부의 탄성체(31) 즉, 인장 및 압축 가능한 코일 스프링에 의해 지지된 쐐기(32) 형태로, 홀드부재(20) 후단에 배치된다. 홀드부 재(20)는 전·후단부 각각 소정의 경사면 형태로 이루어지되, 전단부는 맞닿은 견인부재(50)와의 경계 기울기가 동일하게 형성되고, 후단부는 쐐기(32)와의 경계 기울기가 동일하게 형성된 형태가 좋다. 이와 같은 경계면의 기울기는 리벳의 핀을 압착 고정한 홀드부재(20)가 견인부재(50)에 의해 견인되면서 리벳 핀에 인장력을 가해 끊어졌을 때, 쐐기(32)와의 경계면을 타고 오르도록 함으로써, 절단된 리벳 핀에 대한 압착상태를 해지시키는 역할을 하게 된다.The release means 30 is disposed at the rear end of the holding member 20 in the form of a wedge 32 supported by an elastic body 31, that is, a coil spring that is tensionable and compressible within the barrel 92. Hold member 20 is formed in the form of a predetermined inclined surface of the front and rear, respectively, the front end is formed in the same boundary slope with the traction member 50 abut, the rear end is formed with the same slope inclination with the wedge 32 Good form The inclination of the boundary surface is cut by causing the holding member 20, which is press-fixed to the rivet pin, to be pulled by the traction member 50 and applied to the rivet pin to break, thereby climbing on the interface with the wedge 32. It acts to release the crimp on the rivet pin.

또, 총열(92) 후단에는 핀수거함(80)을 구비하되, 탈부착이 자유로운 형태에 의해 작업여건에 따라 작업자가 선택적으로 적용할 수 있도록 한다. 핀수거함(80)의 탈부착 형태는 도면에서처럼 나사식 체결방식으로도 좋고, 소정 형태의 걸림쇠에 의한 홈 결합방식 등 다양한 형태로 실시될 수 있다.In addition, the rear end of the barrel 92 is provided with a pin collection box (80), so that the operator can selectively apply according to the working conditions by the removable form. Detachable form of the pin collection box 80 may be a screw-type fastening method, as shown in the drawing, it may be implemented in various forms, such as a groove coupling method by a predetermined form of a latch.

본 발명의 전동식 핸드리벳건은 도면에서 도시한 바와 같이 소정형태의 건전지를 장착할 수 있는 형태로도 좋으나, 콘센트 등과의 연결을 통해 전원을 인가하는 전원플러그가 일체로 구비된 형태 등으로도 얼마든지 적용 가능하다.The electric hand rivet gun of the present invention may have a shape in which a predetermined type of battery may be mounted as shown in the drawing, but the power hand rivet gun may be provided in a form in which the power plug is applied integrally through a connection with an outlet. Is applicable.

이하에서는 본 발명의 바람직한 실시형태에 따른 구성 간의 작동관계를 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings, the operating relationship between the configuration according to a preferred embodiment of the present invention.

도 3 내지 4에서 도시한 바와 같이, 본 발명의 전동식 핸드리벳건은 리벳 몸 통을 접합하고자 하는 판재에 뚫린 구멍에 삽입한 상태에서 작업자가 전원인가를 위한 트리거(93)를 당겨 주는 동작만으로 간편하게 리벳작업을 완료하게 된다. 더 구체적인 구성 간의 작동관계는 아래와 같다.As shown in Figures 3 to 4, the electric hand rivet gun of the present invention is simply by the operation of pulling the trigger 93 for the power supply in the state in which the rivet body is inserted into the hole drilled in the plate to be bonded The riveting is completed. The working relationship between more specific configurations is as follows.

먼저, 도 3에서처럼 리벳의 핀이 총구(91)의 노우즈(10)를 통해 삽입되면, 홀드부재(20)의 이빨 사이에 물려 압착 고정된다. 이러한 상태에서 해당 판재의 구멍에 리벳 몸통을 끼워 넣고, 트리거(93)를 작동시켜 전원을 인가한다.First, when the pin of the rivet is inserted through the nose 10 of the muzzle 91 as shown in Figure 3, it is clamped and fixed between the teeth of the holding member 20. In this state, the rivet body is inserted into the hole of the plate, and the trigger 93 is operated to apply power.

인가된 전원에 의해 구동모터(40)가 작동되면, 구동모터(40)의 플라이휠(41)에 맞물린 휠부재(60)가 회동되고, 이와 연계된 작동링크(70) 및 견인부재(50) 또한 작동하게 된다. 즉, 작동링크(70)에 의해 휠부재(60)의 회전운동이 직선왕복운동으로 전환되면서 견인부재(50)가 후퇴 및 전진을 반복하게 된다.When the drive motor 40 is operated by the applied power, the wheel member 60 engaged with the flywheel 41 of the drive motor 40 is rotated, and the operation link 70 and the traction member 50 associated with the drive motor 40 are also rotated. It works. That is, as the rotational movement of the wheel member 60 is converted into a linear reciprocating motion by the operation link 70, the traction member 50 repeats retreat and forward movement.

후퇴시 견인부재(50)는 홀드부재(20)와 해지수단(30)을 동시에 견인하게 된다. 이때, 홀드부재(20)은 리벳 핀에 인장력을 가하게 되고, 해지수단(30)의 쐐기(32)는 뒤로 물러나면서 코일 스프링 형태의 탄성체(31)를 압축시키게 된다. 탄성체(31)의 압축은 홀드부재(20)의 인장력에 의해 리벳 핀이 절단되면서 판재의 리벳접합이 완료되는 순간까지 이루어지며, 이후 탄성체(31)의 탄지력에 의해 쐐기(32)의 후퇴가 방지된다. 따라서 계속되는 견인부재(50)의 견인력은 홀드부재(20)에만 영향을 미쳐, 쐐기(32)와 접촉된 후단 경계면을 따라 홀드부재(20)를 슬라이딩시키면서, 홀드부재(20)의 각 조각편과 리벳 핀 간의 간격을 소정 폭만큼 이격시키게 된다. 즉, 홀드부재(20)에 의한 리벳 핀의 압착상태를 해지시키게 된다.At the time of retraction, the towing member 50 tow the holding member 20 and the release means 30 simultaneously. At this time, the holding member 20 exerts a tensile force on the rivet pin, and the wedge 32 of the termination means 30 is retracted to compress the elastic body 31 in the form of a coil spring. Compression of the elastic body 31 is performed until the rivet joining of the plate is completed by cutting the rivet pin by the tensile force of the holding member 20, after which the retreat of the wedge 32 by the holding force of the elastic body 31 Is prevented. Accordingly, the traction force of the towing member 50 continues to affect only the holding member 20, sliding each of the pieces of the holding member 20 and the rivet while sliding the holding member 20 along the rear end interface in contact with the wedge 32. The space between the pins is spaced apart by a predetermined width. That is, the crimping state of the rivet pin by the holding member 20 is released.
