Method for position finding and welding of protective plate, small foot and longitudinal beam for aluminum-magnesium alloy tanker by adopting robot

Abstract

The invention relates to a method for finding the welding position during the welding process of a protective plate, a small foot and a longitudinal beam for an aluminum-magnesium alloy tanker by adopting a robot, in particular to a method for position finding and welding of a protective plate, a small foot and a longitudinal beam for an aluminum-magnesium alloy tanker by adopting a robot; the method comprises the following steps: the robot performs automatic moving of locus by utilizing the high voltage between a welding wire and a workpiece according to the specifications in the procedures, the actual position of the workpiece is measured, the derivation between the actual position and the measured position of the workpiece is calculated, and then the robot performs welding according to the corrected locus; and in the method, the welding points are measured during the welding process of the protective plate, the small foot and the longitudinal beam for the aluminum-magnesium alloy tanker by finding the position for the right angle, the small foot and the longitudinal beam of the workpiece through the robot, and then welding is carried out according to the determined points, so that the welding quality and the welding speed of the workpiece are both ensured.

Description

technical field [0001] The invention relates to a method for using a robot to find the welding position in the welding work of aluminum and magnesium alloy tank car guard plates, small feet and longitudinal beams, especially: the location and welding method of welding robots for aluminum and magnesium alloy tank car guard plates, small feet and longitudinal beams . Background technique [0002] At present, in the welding work of aluminum and magnesium alloy tank car guard plates, small feet, and longitudinal beams, although robots are used for welding operations, when welding guard plates, small feet, and longitudinal beams, because of the angle, the robot has no vision. Function, so manual welding work is still required, which not only affects the work progress, but the most important welding quality cannot be better guaranteed. Contents of the invention [0003] The purpose of the invention of the present invention is: to provide aluminum, magnesium alloy tank car guard...
