DEVICE FOR THE WELDING TORCH VIBRATIONS Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: device has housing 1, pointer 15, electromagnet 5 with rod 6, support 17, drive shaft 3 and nut 16 and disk 18 with a traction placed on drive shaft 3. The device is equipped with slide 10 and limit switches 7 and 8. The drive shaft has central hole 9 and grooves 11 and 12 communicating with it. Slide 13 connected with traction 27 with the aid of cantilever 14 is placed in central hole 9. Pointer 15 is set up on cantilever 14. It can interact with limit switches 7 and 8. Slide block 13 engaged with the thread of nut 16 is fixed on slide 10. Nut 16 is equipped with support 17 designed for interacting with rod 6 of electromagnet 5 mounted on housing 1. Advanced rod 6 of electromagnet 5 interacts with support 17 fixing nut 16 relative to housing 1. As a result slide block 13 rotating with drive shaft 13 begins to shift along the thread of nut 16 which results in the displacement of slide 10 in central hole 9 and hence to the change of the slope of dick 18 towards drive shaft 3. The device is used in the mechanized fusing with electrode vibrations. EFFECT: facilitated manufacture. 2 cl, 1 dwg
