Description

Technical Field

[0001] This utility model relates to the field of heat exchange processing, and in particular to a welding and fixing device for the end cap of a heat exchanger that is welded by a robot. Background Technology

[0002] A heat exchanger (also known as a heat exchanger or heat exchange device) is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements; it is an industrial application of convective heat transfer and heat conduction. Heat exchanger end caps are installed at both ends of the shell and are an essential component of the heat exchanger. Existing arc-top type heat exchanger end caps still have some shortcomings in the welding and assembly process. For example, their internal limiting and positioning capabilities are poor during actual use, making it difficult to provide a good reference positioning effect during operation, thus easily affecting the manufacturing process.

[0003] The existing heat exchanger end cover welding and fixing device is unstable when used by operators, which can only fix the material to be welded, thus affecting the processing accuracy. The existing fixture structure is not suitable for robotic assembly line operation. Utility Model Content
