Abstract

The invention relates to an adjustment device of an adjustable roller frame, comprising a first silk pole and a second silk pole, wherein the first silk pole and the second silk pole are axially and fixedly connected through a connecting sleeve, a screw thread direction of the first silk pole is reverse to that of the second silk pole, a matched first screw nut is arranged on the first silk pole in a sleeved way, the outer end of the first silk pole is supported on a first bearing seat, a matched second screw nut is arranged on the second silk pole in the sleeved way, the outer end of the second silk pole is supported on a second bearing seat, and a hand wheel is installed at the outer end of the second silk pole. In the invention, two silk poles with reverse screw thread directions are adopted to drive the corresponding screw nut to move, thereby driving two rollers to move; the invention has the advantages of simple and reliable structure as well as convenient installation and maintenance; the invention can enable the two rollers to simultaneously move toward the middle part or both sides with accurate adjustment; the silk poles are supported on the bearing seats, are flexible to rotate and can simultaneously bear the tension and the thrust.

Description

technical field [0001] The invention relates to an adjustable roller frame for welding cylindrical workpieces, in particular to an adjusting device for the adjustable roller frame. Background technique [0002] The welding roller frame is an auxiliary equipment for welding cylinder workpieces. The adjustable welding roller frame can adjust the distance between the rollers according to the diameter of the cylinder. It can be used together with the operation frame and electric welding machine to realize the internal and external longitudinal welding of cylinder workpieces. Circular seam welding. With the development of the economy, the degree of automation of production equipment is getting higher and higher, and welding roller frames are widely used in the machinery industry. The use of welding rollers greatly improves the quality and appearance of welds. [0003] The existing adjustable roller frame manually adjusts the distance between the rollers, which is time-consuming...
