DEVICE FOR RESISTANCE SLOT WELDING Russian patent published in 1997 - IPC

FIELD: welding equipment; may be used in machines of resistance spot welding with automated feed of welded material to welding zone, in particular, for welding articles of cabins and bodies of automobiles. SUBSTANCE: installed in base 4 with the help of hinges are three axles. One axle 5 is connected with rod 8 of drive 9 for moving of welding electrodes 1 and 2 to welding zone. The ends of two other axles 6 and 7 are located in recesses made in walls 11 and 12 of body 10. In this case, ends of one axle 6 are located in straight recesses 13, while ends of axle 7 are located in shaped recesses 14 with straight sections 15 parallel to straight recesses 13. Sections 16 are made on circumferences whose centers are located on axial lines of straight recesses 13. Radii of axial lines of sections 16 are equal to distance between centers of axles 6 and 7 whose ends are located in straight recesses 13 and shaped recesses 14. Axial lines of straight sections 15 of shaped recesses 14 and axial line of drive 9 for moving the welding electrodes 1 and 2 are located in the same plane with engagement of ends of axle 7. EFFECT: higher efficiency. 2 cl, 4 dwg
