The invention relates to the technical field of resistance
spot welding, in particular to a
cement telegraph pole reinforcement cage automatic binding and
welding integrated device based on PLC control. The device comprises a working
rotating disc rotationally connected with a mounting support, a
machining channel allowing the reinforcement cage to horizontally penetrate through is formed in the center of the working
rotating disc, a conductive wheel and a pressing
assembly are arranged on the same side of the working
rotating disc, and the conductive wheel, the pressing
assembly and the reinforcement cage form a closed conductive loop. When the
diameter of the produced reinforcement cage is small, the axial component force applied to the spiral bar by the cylindrical pressing wheel is guided by the inclined plane of the groove, and forced friction is reduced. When the
diameter of a produced reinforcement cage is large and the reset slope of the circular truncated cone pressing wheel presses a spiral bar, the acting direction of force is more deviated to the radial direction, the axial component force is reduced, and therefore the axial
friction force is reduced. When the reset slope on the periphery of the
round table roll
welding wheel is in contact with the spiral rib, an inclined
contact line along the
conical surface is formed.
