본 발명은 용접로봇을 이용한 자동차용 아암의 용접시 아암본체와 단관을 지지고정하는 용접용 지그에 관한 것이다.The present invention relates to a welding jig for supporting and fixing the arm body and the short pipe when welding the arm for a vehicle using a welding robot.

차종에 따라 형태를 달리하는 여러 종류의 자동차용 아암 중 도 5에서와 같이 대체로 반원형의 아암본체(2) 양단부에 단관(4)(6)이 용접형성되는 아암(A)의 경우 강도보강을 위하여 아암본체(2)가 갖는 단면형상에 따라 단관(4)(6)의 외주면에 걸쳐 대체로 "U"형의 긴 용접면을 갖게 되며 용접작업은 거의 대부분 용접불량을 최소화하고 또 생산성 향상을 위하여 용접로봇에 의존하고 있다.In the case of the arm (A) in which the end pipes (4) and (6) are welded to both ends of the semi-circular arm body (2), as shown in FIG. According to the cross-sectional shape of the arm main body 2, it has a long "U" shaped welding surface over the outer circumferential surface of the short pipes 4 and 6, and most of the welding operations are performed to minimize welding defects and improve productivity. Depends on the robot

현재 이용되고 있는 자동차 아암 용접용 지그는 용접로봇 전방에 지그를 설치하여 상기 지그가 갖는 베이스의 전면 상부에 아암 본체를 고정하는 걸림대와 클램프가 설치되고 그 하부양측에는 단관을 결합고정하는 결속핀이 에어실린더에 의해 좌우로 작동가능케 설치되어 작업자가 지그전방에서 아암본체와 단관을 공급해 주게 되면 그 후방에 갖는 용접로봇의 동작으로 용접이 이루어지도록 구성되어 있다.Currently used jig for arm welding uses a jig installed in front of the welding robot to fix the arm main body on the upper part of the base of the jig, and a clamping pin for coupling and fixing the short pipe on both lower sides thereof. It is installed so as to be operated left and right by the air cylinder, and when the worker supplies the arm main body and the short pipe from the front of the jig, the welding robot is configured to be made by the operation of the welding robot behind it.

그러나 이러한 구조의 지그는 용접로봇이 작업자의 간섭을 피하기 위하여 지그 후방에 설치되고 또 지그의 구조상 공급된 아암본체와 단관 사이에 갖는 전체 용접부위중 일부만 노출되므로 노출된 일부용접구간만 용접이 이루어질 수가 있을 뿐 가려진 나머지 용접구간은 용접이 이루어질 수가 없어 1차용접된 아암을 지그로부터 분리하여 나머지 비용접구간은 수동용접 내지는 별도의 지그와 용접로봇을 통 한 자동용접으로 용접작업을 완료해 주도록 하고 있다.However, the jig of this structure is installed behind the jig to avoid the operator's interference, and only part of the welded part exposed to the welding can be made because only a part of the entire welding part is exposed between the arm main body and the end pipe. Only the remaining welded sections cannot be welded, so the primary welded arm is separated from the jig, and the remaining non-welded sections are completed by manual welding or by automatic welding through a separate jig and welding robot. .

따라서 지그와 용접로봇에 의해 1차용접된 아암을 지그로부터 분리하여 수작업 내지는 별도의 지그와 용접로봇을 이용한 2차용접으로 용접작업이 완료되도록 하는데 시간과 인력이 추가소요되므로 현저한 생산성 저하를 가져오게 되고 또 수작업에 의존할 경우 용접불량발생율이 높을 뿐 아니라 생산성은 더욱 저하되며 별도의 지그와 용접로봇을 이용한 자동용접시에는 수작업에 비해 용접불량을 줄이고 또 용접시간을 단축할 수가 있으나 비싼 지그와 용접로봇을 설치해 주는데 따른 설치비용이 추가소요되는 등의 많은 문제점들이 지적되고 있는 것이다.Therefore, the arm welded by the jig and the welding robot is separated from the jig and the welding work is completed by manual welding or by secondary welding using a separate jig and the welding robot. If you depend on manual operation, not only the welding failure rate is high, but also the productivity is lowered. In case of automatic welding using a separate jig and welding robot, the welding defect can be reduced and the welding time can be shortened compared to manual operation. Many problems have been pointed out, such as additional installation costs for installing the robot.

본 발명은 상술한 종래기술이 갖는 문제점들을 감안하여 1차용접후 아암의 회전에 의한 비용접구간의 노출로 2차용접이 이루어질 수 있도록 하여 현저한 생산성 향상 및 2차용접을 위한 설치비용을 줄일 수 있도록 한 자동차 아암 용접용 지그를 제공하고자 한다.In view of the problems with the prior art described above, the present invention enables the secondary welding to be performed by exposing the cost contact zone by the rotation of the arm after the primary welding, thereby remarkably improving the productivity and reducing the installation cost for the secondary welding. It is intended to provide a jig for welding an automobile arm.

상기한 본 발명의 목적은 걸림대와 클램프를 통하여 아암본체를 결합하고 그 하부 양측에 갖는 좌우 결속핀에 단관을 결합고정한 상태에서 후방에 갖는 용접로봇에 의해 노출된 용접구간의 용접이 이루어지게 되면 아암본체를 가압고정하는 클램프의 언클램핑후 좌우결속핀의 샤프트가 갖는 피니언기어와 랙기어에 의한 아암의 회전으로 비용접구간이 노출되어 용접로봇에 의한 2차용접이 이루어질 수 있도록 한 자동차 아암 용접용 지그에 의해 달성된다.The above object of the present invention is to arm the arm through the coupling and the clamp and the welding of the welding section exposed by the welding robot having a rear in the fixed state coupled to the left and right binding pins on the lower both sides of the arm is made After unclamping clamp clamping the main body, arm welding by pinion gear and rack gear of left / right binding pin shaft exposes the non-contact section so that secondary welding by welding robot can be performed. Is achieved by jig.

도 1은 본 발명의 정면구성도로서, 본 발명은 프레임(8) 상부에 갖는 베이스(10)의 전면 상부에 아암본체(2)를 결합고정하는 걸림대(12)와 클램프(14)(16)가 설치되고 상기 걸림대(12)의 하부 양측에는 각각 클램프(18)와 스토퍼블록(20)의 도움으로 아암(A)의 단관(4)(6)을 결합고정하는 결속핀(22)(24)이 에어실린더(26)(28)에 의해 작동하도록 설치되고 상기 결속핀과 에어실린더 사이에 연결되어 결속핀과 함께 회전하는 샤프트(30)(32)에는 키와 키홈을 통하여 결합되는 피니언기어(34)(36)가 설치되고 상기 피니언기어(34)(36)는 각각 에어실린더(38)(40)에 의해 작동하는 랙기어(42)(44)와 치합되며 결속핀의 하부전방에는 아암본체(2)를 받쳐주는 받침대(46)가 고정설치된다.1 is a front configuration diagram of the present invention, the present invention is a hanger 12 and the clamp 14, 16 for fixing the arm body 2 to the upper portion of the front surface of the base 10 having the upper frame 8 Binding pins (22) and (24) are installed on both lower sides of the hanger (12) to couple and secure the short pipes (4) and (6) of the arm (A) with the help of the clamps (18) and the stopper block (20), respectively. The pinion gear 34 is installed to operate by the air cylinders 26 and 28 and is coupled between the binding pin and the air cylinder and rotates together with the binding pins via the key and the key groove. 36 is installed and the pinion gears 34 and 36 are engaged with the rack gears 42 and 44 operated by the air cylinders 38 and 40, respectively. 2) a support 46 supporting the fixed is installed.

상기에서 아암본체(2)를 결합고정하는 걸림대(12)와 클램프(14)(16) 중 걸림대(12)는 아암본체(2)가 갖는 형상에 따라 베이스(10)로부터 수개의 걸림봉이 돌출형성된 것이나 이외에 아암본체(2)가 결합될 수 있는 형태이면 모두 만족하며, 클램프(14)(16)는 베이스(10)에 핀으로 연결된 가압대와 상기 가압대를 작동하는 에어실린더로 구성되어 걸림대(12)에 결합된 아암본체(2)를 가압고정해 주게 된다.In the hanger 12 and the clamps 14 and 16 for coupling and fixing the arm body 2, the hanger 12 has a plurality of locking rods protruding from the base 10 according to the shape of the arm body 2. If the arm body (2) in addition to the form that can be coupled to all satisfies, the clamp 14, 16 is composed of a pressing rod connected to the base pin by a pin and an air cylinder for operating the pressing rod ( The arm main body 2 coupled to 12 is fixed by pressure.

또한 아암(A)의 단관(4)(6)을 결합고정하는 결속핀(22)(24)은 단관(4)(6)내에 여유있게 삽입될 수 있는 형태로서 에어실린더(26)(28)에 의해 좌우로 슬라이딩작동하며 그 외면에는 단관(4)(6)의 키홈(48)과의 결합을 위한 키(50)가 형성된다.In addition, the binding pins 22 and 24 for fastening and fastening the short pipes 4 and 6 of the arm A may be inserted into the short pipes 4 and 6 in an air cylinder 26 and 28. Sliding from side to side by the side and the outer surface is formed with a key 50 for coupling with the key groove 48 of the short pipe (4) (6).

상기 결속핀(22)(24)과 에어실린더(26)(28)를 연결하는 샤프트(30)(32)는 실린더브라켓(52)(54)내에 설치되는 피니언기어(34)(36)를 관통하여 결속핀과 함께 에어실린더(26)(28)의 실린더봉으로부터 회전가능케 연결설치되고 상기 피니언기어 (34)(36)와 치합되는 랙기어(42)(44)는 그 하부에 연결된 에어실린더(38)(40)의 작동으로 LM가이드를 따라 직선운동하도록 구성된다.The shafts 30 and 32 connecting the binding pins 22 and 24 and the air cylinders 26 and 28 pass through pinion gears 34 and 36 installed in the cylinder brackets 52 and 54. And the rack gears 42 and 44 rotatably connected to the pinion gears 34 and 36 are rotatably installed from the cylinder rods of the air cylinders 26 and 28 together with the binding pins. 38) 40 is configured to linearly move along the LM guide.

그러나 좌우결속핀에 의한 아암(A)의 회전은 1차용접후 이루어지게 되므로 어느 한 결속핀에만 랙과 피니언에 의한 회전력이 주어지도록 하더라도 무방하며 그 회전력 또한 랙과 피니언이 아닌 모터의 동력을 이용할 수도 있는바 본 발명은 결속핀에 회전력을 부여하여 1차용접된 아암을 일정각도 회전시켜 줄 수 있는 구조이면 모두 만족한다.However, since the arm (A) is rotated by the left and right binding pins after the primary welding, the rotational force of the rack and pinion may be given only to one of the binding pins. The present invention also satisfies all of the structures that can rotate the primary welded arm by a predetermined angle by applying a rotational force to the binding pin.

또한 일측 결속핀(22) 외측에 갖는 클램프(18)는 가압대와 상기 가압대를 작동하는 에어실린더로 구성되어 클램핑시 결속핀(22)에 결합된 단관(4)을 가압고정하며 타측 결속핀(24) 외측에 갖는 스토퍼블록(20)은 베이스(10)에 고정된 베어링블록으로부터 회전가능케 연결설치되어 결속핀(24)의 전진으로 상기 결속핀에 결합된 단관(6)과 접촉하여 가압고정이 이루어지게 되고 또 가압고정상태에서 회전이 이루어지게 되나 이외에 결속핀에 결합된 단관이 용접시 정위치를 유지할 수 있는 수단을 갖는 것이면 모두 만족한다.In addition, the clamp 18 having an outer side of the binding pin 22 is composed of a pressurizing rod and an air cylinder for operating the pressurizing rod to pressurize and fix the short pipe 4 coupled to the binding pin 22 when clamping, and the other binding pin. (24) The stopper block 20 having an outer side is rotatably connected from a bearing block fixed to the base 10 and is fixed in contact with the end pipe 6 coupled to the binding pin by the forward of the binding pin 24. If this is made and the rotation is made in the pressure-fixed state, but satisfies all if the end pipe coupled to the binding pin has a means for maintaining the position in welding.

그리고 결속핀(22)(24)의 하부전방에 갖는 받침대(46)는 아암본체(2)를 안정감있게 받쳐줄 수 있는 형태로서 걸림대(12)에 결합된 아암본체(2)가 단관(4)(6)과의 1차용접후 결속핀(22)(24)을 축으로 한 회전시 약100~140° 회전각에서 받침이 이루어질 수 있는 위치에 형성되나 단관(4)(6)이 결속핀(22)(24)과 키와 키홈에 의해 결합되어 결속핀으로부터도 충분한 지지력을 얻게 되므로 받침대는 반드시 필요로 하는 것은 아니다.And the pedestal 46 having the lower front of the binding pins (22) and (24) is a form that can support the arm body (2) in a stable sense, the arm body (2) coupled to the hanger (12) is a short pipe (4) ( 6) After the primary welding with the binding pin (22, 24) is rotated about the axis is formed at a position where the support can be made at a rotation angle of about 100 ~ 140 °, but the single tube (4) (6) is the binding pin ( 22) (24) and the base are combined with the key and the keyway to obtain sufficient support from the binding pin, so the pedestal is not necessary.

본 발명은 작업자가 지그(B) 전방에서 걸림대(12)와 클램프(14)(16)을 통하여 아암본체(2)를 결합고정하고 전진한 일측 결속핀(22)과 후퇴한 타측 결속핀(24)에 단관(4)(6)을 공급하여 일측 결속핀(22)에 공급된 단관(4)은 클램프(18)의 작동으로 고정되게 하고 타측 결속핀(24)에 공급된 단관(6)은 에어실린더(28)에 의한 결속핀(24)의 전진으로 스토퍼블록(20)과 접촉하여 고정되게 한 상태에서 용접로봇(C)의 동작으로 전체용접구간 중 노출된 구간의 1차용접이 이루어지도록 하는 것은 종래와 같다.According to the present invention, the operator engages and secures the arm body 2 through the hanger 12 and the clamps 14 and 16 in front of the jig B, and the one side binding pin 22 which is advanced and the other side binding pin 24 which are retracted. The short pipe 4 supplied to the single binding pin 22 by supplying the short pipe 4 and 6 to the c) is fixed by the operation of the clamp 18, and the short pipe 6 supplied to the other binding pin 24 is The first welding of the exposed section of the entire welding section is performed by the operation of the welding robot C in a state in which it is fixed in contact with the stopper block 20 by advancing the binding pin 24 by the air cylinder 28. It is the same as before.

다만 이때 이용되는 단관(4)(6)은 제작시 그 내면에 키홈(48)이 형성되어 있어 결합시 결속핀(22)(24)과는 키(50)와 키홈(48)에 의한 결합이 이루어지게 된다.However, the short pipes 4 and 6 used at this time have a key groove 48 formed on the inner surface thereof during manufacture so that the coupling pins 22 and 24 are engaged by the key 50 and the key groove 48 when combined. Will be done.

따라서 아암(A)의 1차용접후 수동조작 내지는 제어기의 제어로 아암본체(2)를 가압고정하는 클램프(14)(16)가 후퇴케 하고 에어실린더(38)(40)를 통하여 랙기어(42)(44)를 전진작동시켜 주게 되면 이와 치합된 피니언기어(34)(36)가 회전하게 되고 상기 피니언기어(34)(36)와 키와 키홈을 통하여 결합되는 샤프트(30)(32)가 결속핀(22)(24)과 함께 회전하면서 단관(4)(6)을 통하여 결속핀(22)(24)과 키와 키홈에 의해 결합되는 1차용접된 아암(A)을 회전시켜 주게 된다.Therefore, after the primary welding of the arm A, the clamp 14 and 16 for pressing and fixing the arm main body 2 by the manual operation or the control of the controller retreat and the rack gear (through the air cylinder 38 and 40). 42) (44) to move forward and the pinion gear (34, 36) meshed with it is rotated and the shaft 30, 32 coupled to the pinion gear (34) 36 through the key and key groove Rotate the primary welded arm (A) coupled by the binding pins (22) and (24) and the key and the key groove through the short pipe (4) and (6) while rotating together with the binding pins (22) and (24). do.

이때 아암(A)은 걸림대(12)로부터 약100~140°회전각에서 아암본체(2)가 그 하부전방에 갖는 받침대(46)와 접촉하여 받침이 이루어지게 되고 또 전체 용접부위중 1차용접시 가려져 있던 비용접부위가 상향노출되므로 이후 용접로봇(C)의 동작으로 노출된 비용접부위를 2차용접하여 용접작업을 완료해 주면 된다.At this time, the arm A comes in contact with the pedestal 46 which the arm main body 2 has at its lower front at a rotation angle of about 100 to 140 ° from the hanger 12, and the first welding of the entire welding site. Since the hidden non-welded portion is exposed upward, the welding operation may be completed by performing secondary welding on the non-welded portion exposed by the operation of the welding robot (C).

아암의 용접 완료후에는 종전과 같이 에어실린더(26)(28)를 통한 결속핀 (22)(24)의 후퇴로 아암(A)이 지그(B)로부터 분리되어 회수되며 용접완료된 아암(A)의 분리후 아암본체(2)와 단관(4)(6)을 재공급하고 용접작업을 재개시켜 주는 것으로 연속작업이 이루어지게 된다.After the welding of the arm, the arm (A) is recovered from the jig (B) by retraction of the binding pins (22) and (24) through the air cylinders (26) and (28) as before. After the separation of the arm body (2) and the short pipe (4) (6) to re-supply and to resume the welding operation is a continuous operation is made.

이상에서와 같이 본 발명은 지그(B)가 갖는 걸림대(12)와 클램프(14)(16) 및 결속핀(22)(24)을 통한 아암본체(2)와 단관(4)(6)의 공급으로 요구되는 전체용접부위 중 노출된 일부용접부위의 1차용접이 이루어지도록 한 다음 랙과 피니언을 통하여 결속핀(22)(24)에 주어지는 회전력에 의한 1차용접된 아암(A)의 회전으로 나머지 용접부위가 노출되게 하여 2차용접으로 용접작업을 완료해 주도록 하므로서 종전 1차용접후 아암을 지그로부터 분리시켜서 수작업 내지는 별도의 지그와 용접로봇에 의해 2차용접이 이루어지도록 하는데 비해 용접시 필요한 시간과 인력을 줄일 수가 있어 현저한 생산성 향상을 가져올 수가 있고 또 2차용접을 위한 별도의 지그와 용접로봇을 설치운용하는데 따른 비용을 절감할 수가 있는 등의 효과를 기대할 수가 있는 것이다.As described above, according to the present invention, the arm body 2 and the short pipe 4 and 6 of the arm 12 and the clamp 14, 16 and the binding pins 22 and 24 of the jig B have the same. The primary welding of the exposed part of the entire welding area required by the supply is made, and then the rotation of the primary welded arm A by the rotational force given to the binding pins 22 and 24 through the rack and pinion. In order to complete the welding work by secondary welding by exposing the remaining welding parts, the secondary welding is performed by manual or separate jig and welding robot by separating the arm from the jig after the first welding. It can reduce the time and manpower required, which can lead to remarkable productivity improvement and reduce the cost of installing separate jig and welding robot for secondary welding.
