TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial machinery, in particular to a position changing device for industrial welding. BACKGROUND

[0002] With the progress and development of science, welding technology has been more and more widely used. Welding, also known as fusion welding, is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics.

[0003] In the field of mechanical manufacturing or automobile manufacturing, welding is needed to weld mechanical parts or components into one body by an electric welding machine. Artificial electric welding or mechanical electric welding is generally used. In the prior art, a corresponding fixed clamp is generally used to clamp the workpiece for welding. Since the positions of the workpiece that need to be spot welded are distributed in various directions, after completing the welding work on one working surface of the workpiece, the workpiece needs to be released and then the workpiece needs to be turned over for continuous welding. This clamping and fixing method is relatively complicated to operate and requires a large amount of labor cost. SUMMARY
