자동차 트레일링암과 스핀들 플레이트 용접용 클램핑장치{CLAMPING APPARATUS FOR WELDING OF AUTOMOBILE TRAILING ARM AND SPINDLE PLATE}CLAMPING APPARATUS FOR WELDING OF AUTOMOBILE TRAILING ARM AND SPINDLE PLATE}

본 발명은 자동차의 트레일링암에 스핀들 플레이트를 용접할시 스핀들 플레이트에 원하는 용접각을 부여해 주기 위한 스핀들 플레이트 클램핑장치에 관한 것이다.The present invention relates to a spindle plate clamping device for giving a desired welding angle to the spindle plate when welding the spindle plate to the trailing arm of the vehicle.

일반적으로 자동차 후륜현가장치는 토션빔 양측에 트레일링암이 용접고정되고 또 좌우트레일링암에는 각각 스핀들 플레이트가 용접고정되어 바퀴의 회전을 위한 스핀들은 스핀들 플레이트를 통하여 회전가능케 결합해 주도록 구성된다.In general, a vehicle rear wheel suspension device is welded and fixed on both sides of the torsion beam, and the spindle plate is welded and fixed to the left and right trailing arms, respectively, so that the spindle for rotation of the wheel is rotatably coupled through the spindle plate.

또한 스핀들 플레이트는 트레일링암으로부터 주어지는 용접각이 바퀴의 토인각을 결정하게 되므로 트레일링암에 용접고정할 시에는 바퀴에 부여하고자 하는 토인각에 따라 트레일링암으로부터 미리 주어진 용접각을 유지하도록 용접고정해 주는 것이 바람직하다.In addition, since the welding angle given from the trailing arm determines the toe angle of the wheel, the spindle plate is welded and fixed to maintain a predetermined welding angle from the trailing arm according to the toe angle to be given to the wheel when fixing to the trailing arm. It is preferable.

그러나 이제껏 트레일링암에 스핀들 플레이트를 용접고정할 시에는 단순히 눈대중으로 트레일링암의 용접면에 스핀들 플레이트를 긴밀히 접촉시켜서 용접이 이루어지도록 한 다음 트레일링암으로부터 부여해 주고자 하는 용접각(토인각)에 따라 스핀들 플레이트를 절삭가공하여 요구되는 용접각(토인각)이 주어지도록 하고 있다.However, when welding the spindle plate to the trailing arm so far, simply contact the spindle plate with the eye of the trailing arm in close contact with the welding plate so that the welding is performed, and then the spindle according to the welding angle (toe angle) to be given from the trailing arm. The plate is cut to give the required welding angle (torque angle).

따라서 매 용접작업시 눈대중으로 트레일링암과 스핀들 플레이트를 결합하여 용접고정한후 원하는 용접각에 따라 스핀들 플레이트를 절삭가공해 주도록 하기 위하여는 고가의 전용절삭가공기를 필요로 하게 되므로 이를 구입하여 운용하는데 많은 비용부담이 발생하게 될 뿐만 아니라 절삭가공작업후에는 각종 이물질들을 제거해 주기 위한 세척을 필요로 하는등 작업인력과 시간이 많이 소요되고 또 이로 인하여 현저한 생산성 저하를 가져오게 되는 등의 많은 문제점들이 있는 것이다.Therefore, in order to fix the welding of the spindle plate according to the desired welding angle after joining the trailing arm and the spindle plate to the eye during every welding operation, an expensive dedicated cutting machine is needed. Not only the burden is generated, but also after the cutting process requires a lot of work manpower and time, such as the need to wash to remove various foreign matters, and there are a number of problems, such as to bring a significant decrease in productivity.

본 발명의 목적은 자동차 후륜현가장치의 스핀들 플레이트와 트레일링암을 용접이음하는 과정에서 스핀들 플레이트가 트레일링암으로부터 요구되는 용접각을 갖도록 할 수가 있는 자동차 트레일링암과 스핀들 플레이트 용접용 클램핑장치를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a clamping device for automobile trailing arm and spindle plate welding, which can make the spindle plate have the required welding angle from the trailing arm in the process of welding the spindle plate and trailing arm of the vehicle rear wheel suspension. .

By advancing by the air cylinder 14, the welding plate is brought into contact with the welding surface of the trailing arm 30 clamped by a separate clamping device so that the welding is performed, so that the spindle plate 28 moves the trailing arm 30 during every welding operation. Since it is possible to weld at all times to maintain a given welding angle at all times, it is possible to significantly reduce overall costs compared to cutting and cleaning operations performed by a cutting machine in order to give a desired welding angle to a conventional spindle plate 28. Not only can this be done, but this can bring about significant productivity gains.
