어스볼트의 스터드 용접시 사용되는 어스볼트척{EARTH BOLT CHUCK FOR STUD WELDING OF STUD BOLT} EARTH BOLT CHUCK FOR STUD WELDING OF STUD BOLT}

본 발명은 어스볼트(EARTH BOLT)의 스터드 용접시 사용되는 어스볼트척에 관한 것이다The present invention relates to an earth bolt chuck used for stud welding of an earth bolt.

일반적으로 어스볼트를 용접건으로 스터드 용접 하는 기술은 자동차 기술 분야에 많이 적용되며 그 외 여러 기술 분야에도 사용되어 오고 있다In general, the technique of stud welding with an earth bolt using a welding gun is widely applied in the field of automobile technology and has been used in many other technical fields.

어스볼트를 스터드 용접 건을 이용하여 스터드 용접 방법은 다음과 같다Stud welding method using earth bolt stud welding gun is as follows.

도 3 에서 보듯이, 어스볼트(미도시)가 척어댑터(34)의 투입구(31)를 통하여 공급되면 피스톤로드(10)가 밀어주어 어스볼트가 어스볼트척(33) 선단부에 고정된다(여기서, 설명의 편의상, 용접건의 그림은 생략하였다. 도 3 의 구성은 용접 건에 일체로 구성되어 장착된다)As shown in FIG. 3, when the earth bolt (not shown) is supplied through the inlet 31 of the chuck adapter 34, the piston rod 10 is pushed to fix the earth bolt to the front end of the earth bolt chuck 33 (where For convenience of explanation, the illustration of the welding gun is omitted. The configuration of FIG. 3 is integrally formed and mounted to the welding gun)

이때 종래의 경우, 피스톤로드(10)의 작동으로 어스볼트를 고속으로 이송시키면, 미끄러운 어스볼트의 원통 외면을 잡아 관성을 가지고 전진하는 어스볼트를 정확히 잡아 어스볼트척(33) 선단 위치에 고정할 수 없었다At this time, in the conventional case, when the earth bolt is transported at a high speed by the operation of the piston rod 10, by grasping the cylindrical outer surface of the slippery earth bolt to accurately grasp the earth bolt to move forward with inertia to fix it to the position of the earth bolt chuck (33) Could not

그 이유는 아래와 같다The reason is as follows.

어스볼트척(33)은 절개부(35)가 형성되어 있어 어스볼트를 잡아 줄 때, 텐션 방식으로 고정한다. 어스볼트를 피스톤로드(10)의 전진으로 피딩시 고속으로 어스볼트를 이송시키면, 그 밀리는 관성에 의해 어스볼트척(33) 선단에서 제 위치에 고정되지 않고 튀어나오거나 탈락하는 경우가 발생한다The earth bolt chuck 33 has a cutout portion 35 formed therein to fix the earth bolt in a tensioning manner. When the earth bolts are fed at high speed when feeding the earth bolts forward of the piston rod 10, the pushing may protrude or fall out of the earth bolt chuck 33 without being fixed in position by the inertia.

종래의 경우, 이를 보완하고자 피스톤로드(10)를 2 번의 움직인다. 즉, 한번은 고속으로 어스볼트척(33)에 살짝 고정시키고 다시 후퇴하였다가 저속으로 전진하여 어스볼트를 척의 원통부와 접하도록 이송시켜준다In the conventional case, the piston rod 10 is moved two times to compensate for this. That is, once fastened slightly to the earth bolt chuck 33 at high speed, retreats again and moves forward at low speed to transport the earth bolt in contact with the cylindrical portion of the chuck.

이와 같이 종래에는 피스톤로드(10)의 2 번 작동으로 어스볼트를 어스볼트척에 장착하므로 그 고정 작업이 번거롭고 작업이 지체되는 단점이 있으며, 상기한 2 번의 피스톤로드(10) 작동에도 불구하고 어스볼트의 정확한 고정에 실패하는 경우가 발생하는 단점이 있다As described above, since the earth bolt is mounted on the earth bolt chuck by the operation of the piston rod 10 twice, the fixing work is cumbersome and the work is delayed, and despite the operation of the piston rod 10 above, the earth The disadvantage of failing to fix the bolt correctly

또한 어스볼트의 용접 후 리프팅시, 용점모재에 어스볼트가 접하였다가 고속으로 후진하면서 아크를 일으켜 용접을 하나, 용융된 쇳물이 접합성을 가지고 있으므로 리프트시 어스볼트척에서 정확히 고정하지 못함으로 슬립이 발생하고 리프트 갭이 발생하여 용접 품질이 크게 저하되어 볼트가 모재에 용접되지 못하고 탈락하는 경우가 발생한다. In addition, when lifting after welding of the earth bolt, the earth bolt is in contact with the molten base material and then retracted at high speed, causing arc to weld, but the molten metal has bonding property, so the slip is not fixed correctly at the earth bolt chuck during lift. And the lift gap is generated, the welding quality is greatly degraded, and the bolt is not welded to the base material and falls out.

본 발명은 이를 해결하기 위한 것으로, 어스볼트척 내부에 홈 가공을 하여 어스볼트를 스터드 용접시 고정성을 향상시키고 피딩시 안정적인 고정, 리프팅시 리프트 갭을 최소화 하기 위한 것이 본 발명의 목적이다.The present invention is to solve this, it is an object of the present invention to minimize the lift gap during lifting, stable fixing at the time of feeding, stable fixing during feeding, by grooving the inside of the earth bolt chuck.

상기한 본 발명의 목적을 달성하기 위한 본 발명의 주요 구성은, 어스볼트척(1)의 선단부 내경에 걸림홈(5)을 갖는 고정부(2)를 형성한 것을 특징으로 하며, 상기한 걸림홈(5)은 경사면(6)과 수직면(7)을 포함하는 것을 특징으로 하며, 상기한 걸림홈(5)에는 어스볼트(3)의 너트원통부(12)가 수용되게 이루어지는 것을 특징으로 하며, 상기한 어스볼트척(1)의 선단부는 그 후단부 보다 그 두께가 더 두껍게 이루어지는 것을 특징으로 하며, 상기한 어스볼트척(1)의 선단부 외경에는 홈(20)을 형성한 것을 특징으로 한다The main configuration of the present invention for achieving the above object of the present invention is characterized in that the fixing portion (2) having a locking groove (5) is formed in the inner diameter of the distal end of the earth bolt chuck (1), The groove (5) is characterized in that it comprises an inclined surface (6) and the vertical surface (7), the locking groove (5) is characterized in that the nut cylindrical portion 12 of the earth bolt (3) is accommodated The tip end of the earth bolt chuck 1 is characterized in that the thickness is made thicker than the rear end thereof, and the groove 20 is formed at the outer diameter of the tip end of the earth bolt chuck 1.

종래의 경우, 어스볼트의 용접 후 리프팅시 어스볼트척이 어스볼트를 물고 고속으로 후진할 경우, 어스볼트척의 텐션이 저하될 경우 어스볼트가 어스볼트척에서 정확히 고정되지 못함으로 슬립이 발생하여 리프트 갭이 발생하여 용접 불량으로 볼트가 모재에 용접되지 못하고 탈락되는 경우가 발생하나 본 발명에서는 걸 림홈(5)에서 어스볼트를 확실히 고정하므로 그러한 문제가 전혀 없다In the conventional case, when the earth bolt chuck bites the earth bolt and retracts at high speed during welding after the earth bolt is welded, when the tension of the earth bolt chuck is lowered, the earth bolt is not accurately fixed to the earth bolt chuck and slips and lifts. There is a case that the gap occurs and the bolt is not welded to the base material due to poor welding, but the fall occurs in the present invention, so the earth bolt is firmly fixed in the locking groove 5, there is no such problem.

본 발명에서는 어스볼트를 스터드 용접시 그 고정성을 최대화 할 수 있고 스터드볼트 피딩 및 리프팅시 탈락과 미끄럼을 방지하여, 안정적인 고정이 가능하고, 리프팅시 리프트 갭을 제거 내지 최소화 하여 용접 품질을 향상할 수 있다In the present invention, the fixing of the earth bolts can be maximized when stud welding, and the fall and slipping can be prevented during the feeding and lifting of the stud bolts, so that the stable fixing is possible, and the lifting gap is removed or minimized when lifting to improve the welding quality. Can

또한 본 발명에 의하면, 피스톤로드(10)의 한번의 작동으로 어스볼트를 어스볼트척에 고정하므로, 종래 2 왕복하는 불필요한 작동을 생략할 수 있어 작업이 신속하게 되어 작업성과 생산성을 크게 향상시킬 수 있다In addition, according to the present invention, since the earth bolt is fixed to the earth bolt chuck by one operation of the piston rod 10, it is possible to omit unnecessary operation to reciprocate two conventionally, so that the work is quick, and the workability and productivity can be greatly improved. have

또한 본 발명에 의하면, 걸림홈(5)에는 어스볼트(3)의 너트원통부(12)와 동일한 형태로 걸림홈(5)이 형성되어 있어서, 그 접촉면적을 넓게 만들어 용접시 발생할 수 있는 쇼트를 예방하고 그로 인해 어스볼트척의 수명을 연장시킬 수 있다In addition, according to the present invention, the locking groove 5 is formed in the same shape as the nut cylindrical portion 12 of the earth bolt (3), so that the contact area is widened to cause a short that can occur during welding Can be used to prolong the life of the earth bolt chuck.

이하, 본 발명을 첨부 도면과 함께 상술한다Hereinafter, the present invention will be described in detail with the accompanying drawings.

도 1 은 본 발명에 따른 어스볼트척(1)을 설명하기 위한 도면이다. 1 is a view for explaining the earth bolt chuck 1 according to the present invention.

도시한 바와 같이, 본 발명에 따른 어스볼트척(1)은 그 선단부에 어스볼트(3)를 잡아주기 위한 고정부(2)를 형성한다As shown, the earth bolt chuck 1 according to the present invention forms a fixing portion 2 for holding the earth bolt 3 at its distal end.

도 2 는 어스볼트척(1)에 대한 상세 단면도이다2 is a detailed cross-sectional view of the earth bolt chuck 1.

도시한 바와 같이, 어스볼트(3)를 잡아 주기 위한 고정부(2)는 그 선단쪽 내경에 걸림홈(5)을 형성한다. 이 걸림홈(5)은 고속으로 전진하는 어스볼트(3)를 그 선단부 위치에 정확히 고정시키는 스토퍼 역할을 한다As shown in the drawing, the fixing portion 2 for holding the earth bolts 3 forms a locking groove 5 in the inner diameter at the tip end thereof. The locking groove 5 serves as a stopper for accurately fixing the earth bolts 3 moving forward at a high speed at the tip position thereof.

걸림홈(5)는 경사면(6)과 수직면(7)이 형성된다. 선단 위치에 선단 방향으로 경사지게 만든 경사면(6)의 경사 각도는 바람직하기로는 약 30-40도 각도를 준다.The locking groove 5 has an inclined surface 6 and a vertical surface 7. The inclination angle of the inclined surface 6 which is inclined in the tip direction at the tip position preferably gives an angle of about 30-40 degrees.

경사 각도를 주는 이유는 어스볼트(3)가 어스볼트척(1)에서 분리가 용이하게 되게 하기 위한 것이다. 즉, 어스볼트의 용접 완료 후, 용접된 어스볼트(3)가 어스볼트척(1)에서 쉽게 분리되게 하기 위한 것이다The reason for giving the inclination angle is for the earth bolt 3 to be easily separated from the earth bolt chuck 1. That is, after welding of the earth bolts, the welded earth bolts 3 are to be easily separated from the earth bolt chuck 1.

경사면(6)의 우측으로는 즉, 걸림홈(5)에는 어스볼트(3)의 너트원통부(12)가 수용되게 한다. 이와 같이 하면, 어스볼트(3)의 너트원통부(12)와 동일한 형태로 걸림홈(5)이 형성되어 있어서, 그 접촉면적을 넓게 만들어 용접시 발생할 수 있는 쇼트를 예방하고 그로 인해 척의 수명을 연장시킬 수 있다To the right of the inclined surface 6, that is, the locking groove 5, the nut cylindrical portion 12 of the earth bolt (3) is accommodated. In this way, the locking groove 5 is formed in the same shape as the nut cylindrical portion 12 of the earth bolt 3, and the contact area is widened to prevent shorts that may occur during welding, thereby extending the life of the chuck. Can be extended

상기한 어스볼트척(1)의 선단부는 그 후단부 보다 그 두께가 더 두껍게 이루어진다. 어스볼트척(1)은 도 2 에 도시한 바와 같이, 내경 두께가 선단이 두껍고 후단이 얇다. 이렇게 만드는 이유는 어스볼트(3)가 후단부에서 선단부로 밀려 나올때는 쉽게 밀려 나오게 하고 선단부에서는 고정을 확실하게 할 수 있을 정도의 강한 탄성을 주기 위한 것이다The tip end of the earth bolt chuck 1 is made thicker than the rear end thereof. As shown in Fig. 2, the earth bolt chuck 1 has a thick inner end and a thin rear end. The reason for this is to make the earth bolt (3) push out easily when it is pushed from the rear end to the front end, and to give strong elasticity enough to secure the fixing at the front end.

또한 상기한 어스볼트척(1)의 선단부 외경에는 홈(20)을 형성하였는데 이것은 그 선단 부위가 지나치게 두꺼워지면 탄성적 고정이 너무 강력하여 지기 때문이다. 즉, 어스볼트(3)가 어스볼트척(1)에서 너무 강력하게 고정되면 어스볼트척((1)에 삽입 및 분리에 있어 작동이 원활하지 못하므로, 오히려 역효과가 발생하므로 바람직하지 못하다. In addition, the groove 20 is formed in the outer diameter of the distal end of the earth bolt chuck 1 because the elastic fixing becomes too strong when the distal end is too thick. That is, if the earth bolt (3) is fixed so strongly in the earth bolt chuck (1) is not preferable because the operation is not smooth in the insertion and removal of the earth bolt chuck (1), rather the adverse effect occurs.
