(54) УСТРОЙСТВО ДЛЯ КОНТАКТНОЙ МНОГОТОЧЕЧНОЙ СВАРКИ(54) DEVICE FOR CONTACT MULTIPLE WELDING

Изобретение относитс к технике получени неразъемных соединений металлов методами контактной точечной электросварки и может быть использовано в различных област х машиностроени , где примен етс контактна сварка при изготовлении особо тонкостенных пространственных конструкций.The invention relates to a technique for producing permanent metal compounds by methods of resistance spot welding and can be used in various fields of mechanical engineering, where contact welding is used in the manufacture of very thin-walled spatial structures.

Известно устройство дл контактной многоточечной сварки, содержащее основание, установленные с возможностью поворота электроды и привод сжати 1.A device for resistance multi-spot welding is known, comprising a base, rotatably mounted electrodes and a compression drive 1.

К недостаткам такой конструкции следует отнести сложные системы подвода тока к электродам, исключение возможности в получении минимального рассто ни между сварными точками и сложность в переналадке машин дл выполнени швов в труднодоступных местах, повтор юш,их конфигурацию нахлестки свариваемой детали.The disadvantages of this design include complex systems for supplying current to the electrodes, eliminating the possibility of obtaining the minimum distance between the welded points and the difficulty in retooling machines for making seams in hard-to-reach places, repeating them, and overlapping the welded part.

20 друга. Каждый из электродов в наборе может независимо от других перемещатьс относительно оси 2 в радиальном направлении .20 friend. Each of the electrodes in the set can, independently of the others, move relative to axis 2 in the radial direction.

Claims

Electrodes-plates 4 are assembled and shifted on axis 2 in such a way that the profile of their working part can correspond to any configuration of the overlap of the parts to be welded, and, consequently, the corresponding location of points in the weld. In order to evenly distribute the compression force P on the working parts of each electrode in the set, an elastic element 5 is used, which is installed between the compression drive and the plate set. The returnable radial rotation of the set of electrodes after the cessation of the force P is effected by the spring 6. The device operates as follows. Along the guides 7, the base 1 together with the set of electrode plates 4 is fed to the welding zone. The drive force P through the elastic element 5 is transmitted to each plate electrode while ensuring the same force when compressing parts 8 and 9 to current-carrying electrodes 10. The welding is performed by passing current from source 13 through the pads 11 by flexible conductors 12 to each insulated top plate ; and the lower sets 4. The welding current from the power source 13 is fed by one pole to the busbars 10 and the other pole to the pads 11. To increase the welding performance, several devices can work simultaneously on common or separate axes of rotation 2 and bases 1, the placement bar of each device is taken depending on the features of the parts and the size of the device itself. After welding one portion of the joint, the device or group of devices moves in the transverse direction to weld the adjacent sections. In case of wear of the working part of one or several electrode plates 4, the latter are easily restored or replaced with new ones. Thus, this device allows to weld points with a minimum distance between them, to increase the productivity and quality of welded joints. Claims. A device for contact multipoints. .-.
