5-shaft linkage numerical control bonding machine and welding process control method thereof

Abstract

The invention relates to a five-axis linkage numerical control welding machine and the welding technique control method thereof. The welding technique control method comprises the following steps: adopting CAD / CAM to build a welding workpiece model; planning and outputting the specific welding spot sequence data; and then carrying out a coordinate conversion and generating a G-code numerical control program file by applying a specific machine tool kinematical formula. The mechanical transmission system ensures the five-axis linkage according to the converted specific welding-spot data, so as to optimize the position between the welding gun and the welding spot while welding, ensure that the welding product has the advantages of good quality uniformity, high repeatability precision, good movement and power performance, etc.; the mechanical transmission system includes three linear movement guide rails X, Y and Z which drive the welding guns to work, and two rotating shafts which drive the welding guns to rotate, wherein the linear movement guide rails can ensure that the rotating shafts can move transversely in any position in the working space, and the two rotating shafts which drive the welding guns to rotate can ensure that the welding guns can perform a 360-degree rotation round the welding spot, therefore, the welding machine and the control method thereof have the advantages of large machine tool stroke, no dead area, high generality, high suitability, etc.

Description

technical field [0001] The invention relates to a welding machine, in particular to a five-axis linkage numerical control welding machine. [0002] The present invention also relates to a technological process, in particular to a technological process in which a computer program is used to realize the operation of a welding machine to weld workpieces. Background technique [0003] In the existing welding equipment, the torch head can only be translated in three-dimensional space, and the angle cannot be changed. Therefore, the position between the torch and the welding spot cannot always reach the optimal state during welding, which often causes welding Pores, slag inclusions and other phenomena will occur in the seam, which will affect the welding quality.

Problems solved by technology

[0003] In the existing welding equipment, the torch head can only be translated in three-dimensional space, and the angle cannot be changed. Therefore, the position between the torch and the welding spot cannot always reach the optimal state during welding, which often causes welding Pores, slag inclusions and other phenomena in the seam will affect the welding quality

[0004] In addition, the current welding machines generally use manual programming to compile the processing program, which can be realized when the weld seam shape of the workpiece is relatively simple, but with the increase of the complexity of the weld seam of the workpiece, the amount of mathematical calculation and the number of program segments also decrease. It will be greatly increased. At this time, it will be extremely difficult or even impossible to complete by relying solely on manual programming.
