RAILS LINING IN CONTACT BUTT WELDING MACHINE

摘要

FIELD: process engineering.SUBSTANCE: invention relates to contact butt welding. Manipulator with distance transducers fitted thereat is fed into rail ends abutting area to correct rail end clamped position with the help of servo gears by driving them vertically and horizontally. Said manipulator is made abut tightly on rolling surface and side face of one of the rails by electromagnets. Said one rail is taken to make a reference base. Used error signal represents the difference in spacing from reference base to rolling surface and from reference base to side rail faces measured by distance transducers.EFFECT: fast and stable alignment.1 dwg
