Description

스터드 용접용 스터드척{Stud chuck for stud welding}Stud chuck for stud welding

본 발명은 스터드 용접용 스터드척에 관한 것으로서 보다 구체적으로는 스터드 용접시에 스터드척의 내부를 통하여 용접부로 이동하는 스터드볼트에 의해 스터드척의 신축부가 확장되어 수명이 저하되는 것을 방지하고 스터드척과 척어댑터를 나사결합 함으로써 긴밀한 결합이 이루어 지게 하여 척어댑터에서 공급되는 전류가 스터드척에 균일하게 공급되도록 하여 스터드볼트의 용접부가 균일하고 견고하게 용착되어 우수한 품질의 제품을 제조할 수 있도록 한 것이다. The present invention relates to a stud chuck for stud welding. More specifically, the expansion and contraction of the stud chuck is prevented by the stud bolt moving to the welding portion through the interior of the stud chuck during stud welding, thereby preventing the lifespan from deteriorating and the stud chuck and the chuck adapter. By screwing together, the tight coupling is made so that the current supplied from the chuck adapter is uniformly supplied to the stud chuck so that the welding part of the stud bolt is uniformly and firmly welded to manufacture a good quality product.

일반적으로 스터드 용접은 환봉이나 볼트 등을 축방향으로 모재와 용접결합하는 것으로 스터드척에 스터드를 고정하여 모재와 접촉시키고 전기를 순간적으로 인가하여 스터드와 모재 사이에 강한 아크를 발생시켜 스터드의 단부와 모재를 용융시킴과 동시에 스터드를 가압함으로서 용융부가 용착되어 모재에 스터드를 결합하게 되는 것이다.In general, stud welding is to weld round rod or bolt to the base material in axial direction.The stud is fixed to the stud chuck to contact the base material and instantaneous application of electricity generates a strong arc between the stud and the base material. By melting the base material and pressurizing the stud, the molten part is welded to bond the stud to the base material.

한편 근래에는 스터드용접을 자동화하는 스터드 용접로봇의 사용이 보편화되 어 있다. Recently, the use of stud welding robots to automate stud welding has become commonplace.

상기에서와 같이 스터드 용접로봇의 사용하여 스터드 용접을 연속반복하기 위하여서는 스터드척이 장치되는 척어뎁터에 스터드볼트 공급장치를 구비하여 공급되는 스터드볼트가 스터드척의 내부를 통하여 용접부로 공급된다.In order to repeat the stud welding by using the stud welding robot as described above, the stud bolt supplied with the stud bolt supply device to the chuck adapter equipped with the stud chuck is supplied to the welding portion through the interior of the stud chuck.

따라서 스터드 용접척의 단부는 내측에서 공급되는 스터드볼트에 의해 확장 및 축소가 연속적으로 이루어 지게 된다.Therefore, the end of the stud welding chuck is continuously expanded and contracted by the stud bolt supplied from the inside.

즉 도 5의 (가)와 (나)에서와 같이 스터드 용접용 스터드척은 상부에 척어뎁터에 끼움되는 결합부와 하단에 지름이 축소되는 고정부로 구성되며 본체의 내부에 볼드관로를 형성하고 외주에 축방향으로 다수의 절개홈을 형성하여 고정부의 내경보다 큰 지름을 가진 스터드볼트가 스터드척의 내부를 통하여 모재에 공급되면 도 5의 (가)에서와 같이 절개홈의 의해 본체가 분할된 스터드척의 고정부가 벌어지게 되어 스터드볼트의 단부가 모재에 접촉하게 되고 스터드척의 고정부는 탄력에 의해 축소되어 스터드볼트의 상부를 밀착고정하게 되고 용접기에서 전기는 스터드척을 따라 스터드볼트에 공급됨으로 스터드볼트와 모재 사이에 아크를 발생시켜 스터드볼트와 모재가 용착되게 되는 것이다. That is, as shown in (a) and (b) of FIG. 5, the stud welding stud chuck is composed of a coupling part fitted to the chuck adapter at the top and a fixing part having a reduced diameter at the bottom thereof, and forming a bold pipe inside the main body. When the stud bolt having a diameter larger than the inner diameter of the fixing part is formed in the circumferential direction in the axial direction and is supplied to the base material through the inside of the stud chuck, the main body is divided by the incision groove as shown in FIG. The fixing part of the stud chuck is opened so that the end of the stud bolt is in contact with the base material. An arc is generated between the base metal and the stud bolt and the base metal to be welded.

본 발명은 상기에서와 같이 스터드 용접을 자동화하는 스터드 용접로봇에 사용되는 스터드척의 내구성을 증대시키고 스터드척에 공급되는 전기가 스터드척에 균일하게 공급될 수 있도록 하여 스터드볼트의 용접부가 균일한 용접이 이루어질 수 있게 한 것이다.The present invention is to increase the durability of the stud chuck used in the stud welding robot to automate the stud welding as described above and to ensure that the electricity supplied to the stud chuck can be uniformly supplied to the stud chuck welding of the stud bolt uniform welding It was made possible.

즉 종래의 스터드볼트 용접척은 상부에 형성되는 결합부가 척어댑터의 내측으로 압입하여 결합하게 되는데, 이를 반복하게 되면 척어댑터의 척결합부가 마모되어 척의 체결력이 약화 될 뿐만 아니라 결합되는 척 또한 척어댑더와 동일한 축선상에 결합되지 못하고 측면으로 휘어진 상태로 결합하게 되는데. 이는 척 및 어댑터의 결합부가 균일하게 밀착하지 못하여 일측에 이격부가 형성되어 통전되는 전기가 균일하게 척에 전달되지 못하게 되는 결점이 있었고 스터드척의 하단 고정부는 내측을 통하여 공급되는 스터드볼트에 확장과 축소가 반복되고 용접열기에 의해 탄성력이 저하됨으로써 사용시간이 증가함에 따라 고정부의 가압력이 점차 약화됨으로써 스터드척의 내구수명이 짧아지게 되는 원인이 되었다. That is, in the conventional stud bolt welding chuck, the coupling portion formed at the upper portion is pressed into the chuck adapter and coupled to the chuck adapter. If repeated, the chuck coupling portion of the chuck adapter is worn out, which weakens the fastening force of the chuck and the chuck is also coupled to the chuck adapter. It is not coupled to the same axis as the side is bent to the side be combined. This is a defect that the coupling part of the chuck and the adapter cannot be uniformly contacted, so that a space is formed at one side, and thus electricity is not evenly transmitted to the chuck, and the bottom fixing part of the stud chuck has expansion and contraction to the stud bolt supplied through the inside. As the use time increases due to repeated repetition and decrease in elastic force due to welding heat, the pressing force of the fixing part gradually decreases, which causes shortening of the durability life of the stud chuck.

관체형으로 형성되어 내측에 볼트관로(103)가 형성되고 외주에 수직방향으로 다수의 절개홈(101)이 형성되며 하부가 축소되는 고정부(102)와 상부에 척어댑터(4)에 결합되는 결합부(2)가 구성되는 종래의 스터드 용접용 스터드척에 있어서; Is formed in a tubular shape is formed in the bolt pipe passage 103 on the inside and a plurality of incision grooves 101 are formed in the vertical direction on the outer periphery and is coupled to the fixed portion 102 and the chuck adapter 4 on the bottom is reduced In the conventional stud welding stud chuck in which the coupling part 2 is comprised;

조임구(3)의 내측에 형성되는 고정공(301)의 일측에 개방홈(302)을 형성하고 개방홈(302)의 양단에 통공(303)을 형성하여 조임구(3)를 스터드척본체(1)에 끼움하여 형성하며 스터드척본체(1) 결합부(2)의 외주둘레에 나사부(202)를 형성하고 결합부(2)와 스터드척본체(1) 사이에 형성되는 돌출단(203)에 대칭하는 절개면을 가공하여 렌치고정부(201)를 형성한 구성으로 되어 Opening hole 302 is formed on one side of the fixing hole 301 formed inside the tightening hole 3 and through holes 303 are formed at both ends of the opening hole 302 to tighten the fastener 3 with the stud chuck main body. (1) is formed by fitting to the stud chuck body (1) protruding end (203) formed on the outer circumference of the coupling portion (2) formed between the coupling portion (2) and the stud chuck body (1) Wrench fixing part 201 is formed by processing the cutting surface symmetric to the

스터트척의 체결부(2)를 나사부(202)로 형성하여 척어댑터(4)와 나사결합하고 스터드척본체(1) 외측에 일측이 개방홈(302)이 형성된 조임구(3)를 부가하여 스터드척본체(1)의 탄성력을 지지할 수 있도록 한 것이다.The fastening part 3 of the stud chuck is formed by the screw part 202, and is screwed with the chuck adapter 4, and a fastener 3 having one side opening groove 302 is formed outside the stud chuck body 1. It is to be able to support the elastic force of the stud chuck body (1).

상기와 같이 되는 본 발명은 스터드척이 나사체결하여 척어댑터(4)와 결합함으로서 스터드척과 척어댑터(4)의 체결부의 면적을 확대하고 긴밀하게 결합하여 척어댑(4)에서 인가되는 전기가 균일한 량으로 스터드척의 둘레에 통전되어 용접되는 스터드볼트(7)의 용접이 균일하게 되어 우수한 품질의 제품을 생산할 수 있고 조임구(3)를 이용하여 고정부의 신축력을 조절할 수 있음으로 스터드척의 수명을 연장하여 생산성이 우수하고 생산원가를 절감할 수 있는 이점이 있다. In the present invention as described above, the stud chuck is screwed to engage with the chuck adapter (4) to expand the area of the fastening portion of the stud chuck and the chuck adapter (4), and closely coupled, so that the electricity applied from the chuck adapter (4) is uniform. The welding of the stud bolt (7), which is energized and welded around the stud chuck in a uniform amount, makes it possible to produce a good quality product, and the elasticity of the fixing part can be adjusted by using the fastener (3). By extending this, there is an advantage that the productivity is excellent and the production cost can be reduced.

이하 첨부된 도면에 의거하여 본 발명의 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

먼저 도 1은 본 발명의 사시도이고 도 2는 본 발명의 분해사시도가 도시되어 있다. 1 is a perspective view of the present invention and Figure 2 is an exploded perspective view of the present invention.

즉 본 발명은 관체형으로 형성되어 내측에 볼트관로(103)가 형성되고 외주에 수직방향으로 다수의 절개홈(101)이 형성되며 하부가 축소되는 고정부(102)와 상부에 척어댑터(4)에 결합되는 결합부(2)가 구성되는 종래의 스터드 용접용 스터드척에 있어서;That is, the present invention is formed in a tubular shape, the bolt pipe 103 is formed on the inside, and a plurality of incision grooves 101 are formed in the vertical direction on the outer circumference thereof, and the fixing portion 102 and the chuck adapter 4 on the lower portion thereof are reduced. In the stud chuck for the conventional stud welding that the engaging portion (2) coupled to the) is configured;

조임구(3)의 내측에 형성되는 고정공(301)의 일측에 개방홈(302)을 형성하고 개방홈(302)의 양단에 통공(303)을 형성되어 "C" 형으로 형성되는 조임구(3)를 스터드척본체(1)에 끼움하여 형성하며 스터드척본체(1) 결합부(2)의 외주둘레에 나사부(202)를 형성하고 결합부(2)와 스터드척본체(1) 사이에 형성되는 돌출단(203)에 대칭하는 절개면을 가공하여 렌치고정부(201)를 형성한 구성이다.Tightening port formed in the "C" shape by forming an open groove 302 on one side of the fixing hole 301 formed inside the fastener 3 and the through hole 303 at both ends of the open groove 302 (3) is formed by inserting the stud chuck body (1) and the threaded portion 202 is formed on the outer circumference of the stud chuck body (1) coupling portion (2) between the coupling portion (2) and the stud chuck body (1) Wrench fixing portion 201 is formed by processing the cut surface symmetrical to the protruding end 203 formed in the.

상기와 같이 되는 본 발명은 척어댑터(4)와 나사결합하여 스터드척본체(1)가 결합되는데. 돌출단(203)에 형성되는 렌치고정부(201)에 렌치를 고정하여 스터드척을 회전하여 결합하게 된다.The present invention as described above is coupled to the chuck adapter (4) and the stud chuck body (1) is coupled. The wrench is fixed to the wrench fixing part 201 formed in the protruding end 203 to rotate and stud the chuck.

한편 조임구(3)는 탄성에 의해 개방홈(302)이 확장 및 축소되며 개방홈(302)을 확장하여 스터드척본체(1)에 끼워 고정부(102)의 탄력성을 보조하게 된다.On the other hand, the fastener 3 is expanded and contracted by the elasticity of the opening groove 302 and expands the opening groove 302 to fit the stud chuck body 1 to assist the elasticity of the fixing portion 102.

스터드척은 하부에 위치하는 고정부(102)가 확장되어 내측의 스터드볼트(7)를 공급하게 되고 스터드볼트(7)가 공급이 완료되면 하단의 고정부(102)가 축소되어 스터드볼트(7)의 일부를 가압밀착하여 잡은 상태에서 전기를 인가하여 스터드볼 트를 모재에 용접하게 되나, 반복되는 확장과 축소로 인하여 스터드척이 노후되면 고정부(102)가 외측으로 휘어져 탄력성이 약해지게 되면 조임구(3)의 탄력성에 의해 스터드척의 고정부(102)가 축소될 수 있도록 하는 것으로 조임구(3)는 스터드척에 결합되는 위치를 달리하여 스터드척에 부가되는 탄력성을 조절하게 된다.In the stud chuck, the fixing part 102 positioned at the lower part is expanded to supply the inner stud bolt 7, and when the supply of the stud bolt 7 is completed, the fixing part 102 at the lower part is reduced to the stud bolt 7. When a part of the press is held in close contact with electricity, the stud bolt is welded to the base material, but when the stud chuck is aged due to repeated expansion and contraction, the fixing part 102 is bent to the outside and the elasticity becomes weak. By allowing the fixing part 102 of the stud chuck to be reduced by the elasticity of the tightening tool 3, the tightening tool 3 adjusts the elasticity added to the stud chuck by changing the position where it is coupled to the stud chuck.

즉 스터드척본체(1)에 결합되는 조임구(3)의 위치가 스터드척본체(1)의 상부에 위치할수록 조임구(3)에 의해 부가되는 스터드척의 조임력은 약해지는 것이며 하향할수록 조임구(3)가 스터드척의 확장력을 제한하게 되어 스터드척의 조임력이 강해지게 되는 것이다. 미설명부호 5는 실린더, 501은 실린더로드, 6은 스터드볼트공급장치, 601은 스터드볼트공급구이다.That is, as the position of the fastener 3 coupled to the stud chuck main body 1 is located at the top of the stud chuck main body 1, the tightening force of the stud chuck added by the fastener 3 becomes weaker, and the downwardly downward tightening force ( 3) limits the expansion force of the stud chuck, and the tightening force of the stud chuck becomes stronger. Reference numeral 5 denotes a cylinder, 501 a cylinder rod, 6 a stud bolt supply device, and 601 a stud bolt supply port.
