DEVICE FOR SURFACING OF WORNOUT SURFACES OF ARTICLES IN FORM OF SOLIDS OF REVOLUTION Russian patent published in 2007 - IPC B23K9/04 B23K37/47 

FIELD: mechanical engineering; welding.

SUBSTANCE: invention relates to device for surfacing of wornout surfaces of articles in form solids of revolution and it can be used for restoring support rolls, wheels of crawler vehicles, cranes and other parts of different diameters. It can be used for surfacing parts of diameter from 159 mm to 1000 mm and larger. Rotation drive 2 of device is made for alternating setting in one of two positions: for surfacing parts of big and small diameters. Distance between positions 4 and 5 of axis of shaft of drive 2 corresponds to difference in radii of parts of big and small diameter to be surfaced. Additional sliding bearings 7 are secured on bed frame 3 at distance corresponding to positions of drive 2. Crossmember can be secured in additional sliding bearings 7 being installed on axle and made up of two relatively fastened perpendicular beams. Small diameter parts are installed on additional rods and secured between beams. Distance between axis of crossmember and axes of additional rods is equal to distance between positions 4 and 5 of axis of shaft of drive 2. Surface parts are secured on rods by means of disk plug 11 with holes 12 attached to end faces of parts. Rods are made hollow and are closed from side of drive 2 by inner plugs 14. Holes are made in rods. Conical branch pipe 13 is arranged by conical part on rod with surfaced part, and it communicates with suction device 15 from opposite side.

EFFECT: increased capacity at surfacing, improved quality, manufacturability, reduced cost of surfacing, improved conditions of operation of personnel from point of view of ecology.
