Abstract

The invention discloses a plasma welding robot. The plasma welding robot comprises rails, a welding car and a plasma power supply; the car is provided with a drive walking mechanism and a bracket thereof, welding gun angle and position adjusting mechanisms and a welding gun bracket; the walking mechanism controls motions in an X-axle rail direction and a Y-axle rail perpendicular direction; the angle adjusting mechanism is provided with an angle sensor for realizing the angle rotating adjustment of a R-axle welding gun; the welding gun position adjusting mechanism provides the position adjustment in Z-axle front and back directions and AVC-axle welding gun firepower line directions; a laser tracking sensor controls the position adjustment of ZX-axle laser points deviated from welding linesfront and back; three contact sensors are arranged on the car; two are used for judging curved surface positions to control the car to walk and to adjust the angle of the welding gun; and one is usedfor measuring local deformation of plates to realize automatic arc height adjustment. The plasma welding robot adopts quickly installed guide rails to realize automatic welding of all-position stainless steel corrugated plate joints through control of a six-axle linkage robot and a welding line laser automatic tracking system by a PLC.

Description

technical field [0001] The invention relates to a welding robot, in particular to a plasma welding robot. Background technique [0002] The main screen wall of the MarkⅢ film-type LNG ship cargo containment system is made of stainless steel plates (304L) with a thickness of 1.2 mm and criss-cross corrugations (304L). The welding is relatively complicated and the welding workload is huge. The production efficiency is low, and the welding quality is not easy to control. Therefore, a high-precision automatic welding robot is needed to meet the needs of automatic welding; the welding robot especially needs to meet the needs of quickly and flexibly changing the angle of the welding torch when the position of the welding torch’s firepower remains unchanged, so as to adapt to the complex shape of the stainless steel corrugated plate of the Mark III film LNG ship The best and reasonable welding torch angle is required for automatic welding to ensure stable and reliable solder joint...
