Welding track obtaining method for shell cover side seam and welding method

Abstract

The invention provides a welding track obtaining method for a shell cover side seam and a welding method. The shell cover side seam refers to a welding seam at the joint of a shell cover and a shell, and a welding track is composed of four linear welding edges of the shell cover side seam and corner welding points on four corners; the position information of the linear welding edges and the corner welding points is determined according to the parameters and the characteristic angle of the shell cover side seam, the welding track is generated according to the position information, a straight line is welded to the linear welding edges of the welding track of the shell cover side seam, and linkage moving welding is conducted on the corner welding points of the corners in a point-by-point arc interpolation mode; and the corresponding welding tracks can be obtained according to the sizes of the shell cover side seams of different specifications, a welding machine is automatically controlled to complete welding, operation is easy, the requirement for operators is lowered, automatic programming is achieved, manual calculation is not needed, efficiency is high, the automatically generated welding tracks are more accurate and safer, equipment damage caused by calculation errors is avoided, and the welding tracks are high in recovery degree and closer to the actual welding side seam size.

Description

technical field [0001] The present application relates to the technical field of computer numerical control, and in particular, relates to a method for obtaining a welding trajectory of a shell cover side seam and a welding method. Background technique [0002] At present, the laser welding of the side seam of the battery case cover of the aluminum case in the industry is mainly controlled by numerical control instructions, and the source of the numerical control instructions is to manually write the welding trajectory code or use the manual teaching mode to collect the welding trajectory points one by one and then input them. [0003] However, the above method is inefficient in generating codes when welding shell side seams of different specifications and sizes, requires operators to have a high level of calculation and programming, and is prone to calculation errors caused by human factors. Contents of the invention [0004] The purpose of the embodiment of the present a...
