Automatic welding positioner

Abstract

The invention provides an automatic welding positioner. The automatic welding positioner includes a lower bracket, a lower rolling ring and an upper rolling ring and a lifting mechanism; the lower bracket is provided with a rolling ring supporting roller assembly and a rolling ring drive assembly; the rolling ring supporting roller assembly is provided with the lower rolling ring, the lower rolling ring and the upper rolling ring are connected through a rolling ring connecting arm to form a complete annular rolling ring, two side walls of the annular rolling ring are each provided with a rolling ring first complete ring component and a rolling ring second complete ring component with different diameters, the lifting mechanism is arranged on the lower bracket at one side of the rolling ring connecting arm, a plurality of rolling ring gear pins are arranged on the lower rolling ring and the upper rolling ring, and the rolling ring drive assembly is arranged on the lower bracket. The automatic welding positioner meets the requirements of large and heavy-duty welding position exchange, can be fast and accurate in positioning, automatic to rotate and simple in operation, and efficiently completes welding work.

Description

technical field [0001] The invention belongs to the field of welding tooling, in particular to a rolling ring positioner. Background technique [0002] In welding technology, welding positioners are often used in the welding of pipes or other large parts. The welding positioner can achieve high-quality welding of circular seam welding, but in actual welding work, there is a lack of support for heavy or large pipe fittings. Displacement fixture, which makes the welding gun around the welding seam when welding heavy, large pipes or other structural parts, the operation is complicated, and the mechanical arm for mechanical welding is higher, and it is easy to cause the welding axial deviation Therefore, in order to meet the working needs of welding and clamping, it is urgent to develop a positioner with simple operation, accurate displacement and strong practicability. Contents of the invention [0003] In view of this, the present invention aims to propose a rolling ring po...
