Automatic brazing material paving and spot welding system and control method thereof

Abstract

The invention relates to an automatic brazing material paving and spot welding system and a control method thereof. The automatic brazing material paving and spot welding system comprises an upright post (1), a movable beam (2), a spot welding machine head (3), a transverse slide table (4) and a rotary table (6) and is characterized in that one end of the movable beam (2) is connected with the spot welding machine head (3); the movable beam (2) is driven to move horizontally in the horizontal direction on the upright post (1) through a servo motor, and the movable beam (2) is driven to move in the vertical direction on the upright post (1) through another servo motor; the spot welding machine head (3) is driven to move horizontally on the transverse slide table (4) in the horizontal direction through a third servo motor; the rotary table (6) is provided with a fixture (7), a weld workpiece is fixed on the fixture (7), and the fixture (7) and the rotary table (6) are driven to rotate through a fourth servo motor; weld strips output from the spot welding machine head (3) cover ribs of the workpiece, and the weld strips are welded and fixed transversely or longitudinally.

Description

technical field [0001] The invention relates to the field of metal resistance welding, in particular to an automatic brazing material laying spot welding system and a control method thereof before vacuum brazing of stainless steel. Background technique [0002] For vacuum brazing with a large welding area, it is required to lay the brazing material on the welding surface before welding. At present, there is no equipment for laying solder automatically. The common method is to manually fix the solder spot welding on the welding surface. Due to the high requirements on the position and flatness of the solder, it is difficult to lay the solder on a curved surface with a large area. [0003] In order to achieve automatic laying of solder and improve the level of welding technology, our company has set up a project to develop an automatic spot welding system for this application. Contents of the invention [0004] The present invention designs an automatic brazing material la...
