Abstract

The invention relates to the technical field of novel welding gun automatic projection welding and spot welding structures, in particular to that one welding gun is adopted to complete automatic switching between a projection welding electrode and a spot welding electrode, and therefore a welding manner that one welding gun can compete automatic projection welding and spot welding is achieved. Automatic connection of a fastener becomes a technology trend of current automobile and home appliance application, and the structure solves the problems that according to a past projection welding part,spot welding connection with a large part plate is performed after a nut, a screw and a small part plate are independently subjected to manual projection welding, the welding efficiency is low, and the labor intensity is large. According to the main technical scheme and the technical key points of the structure, due to linkage that projection welding upper and lower electrode heads and spot welding upper and lower electrode cap structures are fast disassembled from and assembled on a side face automatic projection welding nut feeding structure and a welding production line, fast and automaticswitching between projection welding and spot welding is completed.

Description

technical field [0001] The invention relates to the technical field of a new welding torch automatic projection welding and spot welding structure. Specifically, the same welding torch adopts automatic replacement of the upper and lower electrodes of projection welding and spot welding to complete automatic switching between projection welding and spot welding. Cooperate with the nut automatic conveying structure to achieve the automatic welding mode of projection welding and spot welding. Background technique [0002] The automatic connection of fasteners is the current technical trend. From manual connection to fully automatic connection, it has advantages in reducing personnel, reducing labor intensity, improving the operator's environment, and forming a stream of production lines. [0003] In the current design of metal structural parts of automobiles and home appliances, direct projection welding of metal parts or nuts and screws to another part has begun to be used, es...
